I have an application in which multiple activities are shown in a certain order, which can change based on events in the current activity. I have a "master" activity which manages which activities are shown. Each ativity is started with startActivityForResult() with a requestCode unique to that activity.
When the activity finsishes, I set the resultCode to a value which will have meaning to the master activity. In the master activity's onActivityResult method, I have a switch (requestCode), which will tell me which activity has returned, and in each case block I work with the resultCode to determine which activity to start next.
The problem I'm having, is that at times, seemingly randomly, the application behaves quite erratically, showing activities out of sequence.
I've been unable to replicate the issue while debugging, so all the information I have looks good, but the end users are constantly complaining about the erratic behaviour.
How can I test to see where the problem is?
The code from the master activity's onActivityResult:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case Settings.SCREEN_UPDATE:
ShowActivity(LoginActivity.class, Settings.SCREEN_LOGIN);
break;
case Settings.SCREEN_LOGIN:
if (resultCode == RESULT_OK) {
Settings.CurrentReport = new Report();
Settings.CurrentReport.setUserId(data.getIntExtra("userId", -1));
selectStore();
} else {
finish();
}
break;
case Settings.SCREEN_PRODUCT: // Coming back from the product selection screen
if (resultCode == RESULT_OK) {
ShowActivity(ActionActivity.class, Settings.SCREEN_ACTION);
} else if (resultCode == RESULT_CANCELED){
ShowActivity(OptionsActivity.class, Settings.SCREEN_OPTIONS);
}
break;
case Settings.SCREEN_ACTION: // Coming back from the action screen, regardless of result, show options screen.
ShowActivity(OptionsActivity.class, Settings.SCREEN_OPTIONS);
break;
case Settings.SCREEN_OPTIONS: // All choices return result_ok. Check the "mode" extra
String mode = data.getStringExtra("mode");
processOption(mode);
break;
case Settings.SCREEN_SESSION:
if (resultCode == RESULT_CANCELED) {
ShowActivity(OptionsActivity.class, Settings.SCREEN_OPTIONS);
} else if (resultCode == RESULT_OK ){
ShowActivity(ActionActivity.class, Settings.SCREEN_ACTION);
}
break;
} // switch (requestCode)
} // protected void onActivityResult(int requestCode, int resultCode, Intent data) {
private void processOption(String mode) {
if (mode.equals("select")) {
ShowActivity(ProductActivity.class, Settings.SCREEN_PRODUCT);
} else if (mode.equals("repeat")) {
Settings.CurrentReport.repeatItem();
ShowActivity(ActionActivity.class, Settings.SCREEN_ACTION);
} else if (mode.equals("session")) {
ShowActivity(SessionActivity.class, Settings.SCREEN_SESSION);
} else { // mode equals "end"
confirmFinish();
}
}
private void ShowActivity(Class cls, int requestCode) {
Intent activity = new Intent(this, cls);
startActivityForResult(activity, requestCode);
}
Then, the code from one of the other activities handling the finish() event:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.options);
Button btn;
btn = (Button)findViewById(R.id.btnSelect);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = getIntent();
intent.putExtra("mode", "select");
setResult(RESULT_OK, intent);
finish();
}
});
btn = (Button)findViewById(R.id.btnRepeat);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = getIntent();
intent.putExtra("mode", "repeat");
setResult(RESULT_OK, intent);
finish();
}
});
btn.setEnabled(Settings.CurrentReport.hasPreviousItem());
btn = (Button)findViewById(R.id.btnSession);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = getIntent();
intent.putExtra("mode", "session");
setResult(RESULT_OK, intent);
finish();
}
});
btn = (Button)findViewById(R.id.btnEnd);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = getIntent();
intent.putExtra("mode", "end");
setResult(RESULT_OK, intent);
finish();
}
});
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
Intent i = getIntent();
i.putExtra("mode", "end");
setResult(RESULT_OK, i);
finish();
break;
}
return super.onKeyDown(keyCode, event);
}
Im just guessing, but maybe Intent intent = getIntent(); is causing the problems. You could try to replace it with Intent intent = new Intent();
getIntent() returns the intent that started the current activity and shouldn't be used as a result.

My app has a RecyclerView in the MainActivity with an onClickListener which sends an intent to a DetailActivity. The DetailActivity has a button to go back without doing anything and a button to send an intent to the `Activity.
I already checked other posts in here like How to pass intent with extras to an already running activity and others, but no one results.
Here is a version that I tried:
MainActivity:
#Override
protected void onNewIntent(Intent intent) {
int codPedido = getIntent().getIntExtra("CodPedido",1);
//Toast to test if it's working
Toast.makeText(getApplicationContext(), String.valueOf(codPedido), Toast.LENGTH_SHORT).show();
}
OnClick of RecyclerViewAdapter:
Intent intent = new Intent(context, DetailActivity.class);
intent.putExtra("CodigoPedido", pedidos.get(i).getCodPedido());
intent.putExtra("Local", pedidos.get(i).getLocal());
intent.putExtra("Dia",pedidos.get(i).getDia());
intent.putExtra("Periodo", pedidos.get(i).getPeriodo());
intent.putExtra("urgente", pedidos.get(i).isUrgente());
intent.putExtra("requisitante",pedidos.get(i).getRequisitante());
intent.putExtra("observacoes", pedidos.get(i).getObservacoes());
DetailActivity:
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.action_confirm) {
Intent intent = new Intent(DetailActivity.this, MainActivity.class);
intent.putExtra("CodPedido", codPedido);
startActivityForResult(intent, 1);
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
Edit:
This is what I tried now:
viewHolder.clRow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MainActivity mActivity = new MainActivity();
Intent intent = new Intent(context, DetailActivity.class);
intent.putExtra("CodigoPedido", pedidos.get(i).getCodPedido());
intent.putExtra("Local", pedidos.get(i).getLocal());
intent.putExtra("Dia",pedidos.get(i).getDia());
intent.putExtra("Periodo", pedidos.get(i).getPeriodo());
intent.putExtra("urgente", pedidos.get(i).isUrgente());
intent.putExtra("requisitante",pedidos.get(i).getRequisitante());
intent.putExtra("observacoes", pedidos.get(i).getObservacoes());
mActivity.startActivityForResult(intent, 1);
}
});
and it gives method 'android.app.ActivityThread$ApplicationThread android.app.ActivityThread.getApplicationThread()' on a null object reference
What I was doing before was using the context which is here in the constructor
public RvPedidosAdapter(List<Pedido> pedidos, Context context) {
this.pedidos = pedidos;
this.context = context;
}
like this:
viewHolder.clRow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(context, DetailActivity.class);
intent.putExtra("CodigoPedido", pedidos.get(i).getCodPedido());
intent.putExtra("Local", pedidos.get(i).getLocal());
intent.putExtra("Dia",pedidos.get(i).getDia());
intent.putExtra("Periodo", pedidos.get(i).getPeriodo());
intent.putExtra("urgente", pedidos.get(i).isUrgente());
intent.putExtra("requisitante",pedidos.get(i).getRequisitante());
intent.putExtra("observacoes", pedidos.get(i).getObservacoes());
context.startActivity(intent);
}
});
On Your code please pass startActivityForResult() with intent param with result code and get the result on MainActivity in onActivityResult();
Intent intent = new Intent(context, DetailActivity.class);
intent.putExtra("CodigoPedido", pedidos.get(i).getCodPedido());
intent.putExtra("Local", pedidos.get(i).getLocal());
intent.putExtra("Dia",pedidos.get(i).getDia());
intent.putExtra("Periodo", pedidos.get(i).getPeriodo());
intent.putExtra("urgente", pedidos.get(i).isUrgente());
intent.putExtra("requisitante",pedidos.get(i).getRequisitante());
intent.putExtra("observacoes", pedidos.get(i).getObservacoes());
startActivityForResult(intent, 1);
On your second activity please use this code.
Intent intent = new Intent(DetailActivity.this, MainActivity.class);
intent.putExtra("CodPedido", codPedido);
setResult(RESULT_OK, intent);
finish();
and move to your MainActivity.class to get the result data in onActivityResult() method like this.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_OK){
(data.getIntExtra("CodPedido");
}
}
you can use
startActivityForResult(Intent intent,int requestcode);
I have 3 classes: MainActivity, HighScoreActivity, and GameScreenActivity. I want to go to the GameScreenActivity via MainActivity, and then when the game has finished, pass the score to the HighScoreActivity. Everything gets passed to the GameScreenActivity successfully, but it doesn't go to the onActivityResult in HighScoreActivity.
I believe it's because of the MainActivity having the startActivityForResult, so the GameScreenActivity's finishQuiz() is expecting to return its data to the MainActivity. How would I pass the GameScreenActivity's data to the HighScoreActivity?
MainActivity()
MainActivity(){
...
private void startQuiz() {
String difficulty = spinnerDifficulty.getSelectedItem().toString();
Intent intent = new Intent(getBaseContext(), GameScreenActivity.class);
intent.putExtra(EXTRA_DIFFICULTY, difficulty);
startActivityForResult(intent, REQUEST_CODE_QUIZ);
}
}
GameScreenActivity()
GameScreenActivity(){
...
private void finishQuiz(){
Intent resultIntent = new Intent(getBaseContext(),
HighScoreActivity.class);
resultIntent.putExtra(EXTRA_SCORE, score);
resultIntent.putExtra(EXTRA_DIFFICULTY, difficulty);
setResult(RESULT_OK, resultIntent);
startActivity(resultIntent);
}
}
HighScoreActivity()
HighScoreActivity(){
...
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE_QUIZ){
if (resultCode == RESULT_OK) {
int score = data.getIntExtra(GameScreenActivity.EXTRA_SCORE, 0);
String difficulty = data.getStringExtra(GameScreenActivity.EXTRA_DIFFICULTY);
if (score > highScore10) {
updateHighscore(score, difficulty);
}
}
}
}
}
-------------------------------------------------------------
Trying with the Broadcast method:
GameScreenActivity() with broadcasting methods
GameScreenActivity(){
...
private void finishQuiz(){
Log.d("sender", "Broadcasting message");
Intent intent = new Intent("scoreEvent");
intent.putExtra(EXTRA_DIFFICULTY, difficulty);
intent.putExtra(EXTRA_SCORE, score);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
sendBroadcast(intent);
Intent goToHighScores = new Intent(getBaseContext(), HighScoreActivity.class);
startActivity(goToHighScores);
}
}
HighScoreActivity() with broadcasting methods
HighScoreActivity(){
...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_high_score);
LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
new IntentFilter("scoreEvent"));
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE_QUIZ){
if (resultCode == RESULT_OK) {
int score = data.getIntExtra(GameScreenActivity.EXTRA_SCORE, 0);
String difficulty = data.getStringExtra(GameScreenActivity.EXTRA_DIFFICULTY);
if (score > highScore10) {
updateHighscore(score, difficulty);
}
}
}
}
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String message = intent.getStringExtra("message");
Log.d("receiver", "Got message: " + message);
}
};
#Override
protected void onDestroy() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
super.onDestroy();
}
}
Considering HighScoreActivity is running,
You can utilize LocalBroadcastManager to register local broadcastReceiver in HighScoreActivity with IntentFilter. Also, don't forget to unregister in onDestroy()
Now, instead of setResult do sendBroadcast() from GameScreenActivity
Hope this helps. Happy coding!
My android app has three buttons On click all the button do the same work,
And the code is so long I don't want to copy the code 3 time.
So, how can I do this using a method?
This the code of one button
public void onClick(View v) {
switch (v.getId()) {
case R.id.Btn1:
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1); //Gallery acessing
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
super.setContentView(R.layout.activity_view);
selectedImage = (ImageView) findViewById(R.id.selectedImage); //Onresult redarct to anothr activity
}
Uri photoUri = data.getData();
if (photoUri != null) {
try {
currentImage = MediaStore.Images.Media.getBitmap(this.getContentResolver(), photoUri);
selectedImage.setImageBitmap(currentImage);
} catch (Exception e) {
e.printStackTrace();
Intent myIntent = new Intent(this, ViewActivity.class);
startActivity(myIntent); //switch activity
}
}}
}
You can try the below code. I have created a public method doSomething() which is called on each button click so it performs the same function whenever it is called.
public void onClick(View v) {
switch (v.getId()) {
case R.id.Btn1:
doSomething();
break;
case R.id.Btn2:
doSomething();
break;
}
}
public void doSomething(){
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1); //Gallery acessing
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
super.setContentView(R.layout.activity_view);
selectedImage = (ImageView) findViewById(R.id.selectedImage); //Onresult redarct to anothr activity
}
Uri photoUri = data.getData();
if (photoUri != null) {
try {
currentImage = MediaStore.Images.Media.getBitmap(this.getContentResolver(), photoUri);
selectedImage.setImageBitmap(currentImage);
} catch (Exception e) {
e.printStackTrace();
Intent myIntent = new Intent(this, ViewActivity.class);
startActivity(myIntent); //switch activity
}
}}
}
private View.OnClickListener myClickListener = new View.OnClickListener(){
public void onClick(View view){
//do all the work here
}
}
then set it in you Views
view1.setOnClickListener(myClickListener);
view2.setOnClickListener(myClickListener);
//... etc
You can Use performClick of first button in other views click.
Button button1 = findViewById(R.id.Btn1)
case R.id.Btn2:
button1.performClick()
I have 2 Activity.
FirstActivity with 1 textView and 1 button, and
MainActivity with 4 checkBoxes, 1 textView and 1 button.
First Activity is the first activity which app show to user.
Layouts of my activities
On the FirstActivity i want to check how many checboxes are checked in the textView.
On the MainActivity all working fine, we can select checkboxes and textView show how many is checked. Adittionaly, state of checkboxes and state of textView is save into SharedPreference.
Now i describe my problem, i dont know how to show currently numbers of checked boxes in 1st activity in my app after launch.
I tried to use onActivityResult but i think i do this wrong, and this my button2 with double intent must be also wrong.
What i should fix here and how ?
I paste here code of my 2 Activities:
FirstActivity :
public class FirstActivity extends AppCompatActivity {
private static final String SHARED_PREFS_NAME = "abc";
private Button b1;
private TextView tv2;
private int number;
public static final int REQUEST_CODE = 100;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
b1 = (Button)findViewById(R.id.b1);
tv2 = (TextView)findViewById(R.id.tv2) ;
b1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent intent = new Intent(FirstActivity.this, MainActivity.class);
startActivityForResult(intent, REQUEST_CODE);
}
});
SharedPreferences preferences = getSharedPreferences(SHARED_PREFS_NAME, MODE_PRIVATE);
number = preferences.getInt("NUMBER", 0);
tv2.setText(""+number);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_CODE) {
int number = data.getExtras().getInt("number");
tv2.setText(""+number);
number = getIntent().getExtras().getInt("number");
saveNumberToSharedPrefs(number);
}
}
}
private void saveNumberToSharedPrefs(int num){
SharedPreferences preferences = getSharedPreferences(SHARED_PREFS_NAME, MODE_PRIVATE); //Create and store this instance in onCreate method of activity, or use it like this.
preferences.edit().putInt("NUMBER", num).apply(); // Use constant value for key
}
}
MainActivity :
public class MainActivity extends AppCompatActivity implements CompoundButton.OnCheckedChangeListener {
private int numberOfTrue;
private TextView tv1;
private CheckBox cb1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CheckBox cb2,cb3,cb4;
Button b2;
b2 = (Button)findViewById(R.id.b2);
tv1 = (TextView)findViewById(R.id.tv1);
cb1 = (CheckBox)findViewById(R.id.cb1);
cb1.setChecked(getFromSP("cb1"));
cb1.setOnCheckedChangeListener(this);
cb2 = (CheckBox)findViewById(R.id.cb2);
cb2.setChecked(getFromSP("cb2"));
cb2.setOnCheckedChangeListener(this);
cb3 = (CheckBox)findViewById(R.id.cb3);
cb3.setChecked(getFromSP("cb3"));
cb3.setOnCheckedChangeListener(this);
cb4 = (CheckBox)findViewById(R.id.cb4);
cb4.setChecked(getFromSP("cb4"));
cb4.setOnCheckedChangeListener(this);
loadVariable();
b2.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent output = new Intent();
output.putExtra("number", numberOfTrue);
setResult(Activity.RESULT_OK, output);
finish();
}
});
}
private boolean getFromSP(String key){
SharedPreferences preferences = getApplicationContext().getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);
return preferences.getBoolean(key, false);
}
private void saveInSp(String key,boolean value) {
SharedPreferences preferences = getApplicationContext().getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putBoolean(key, value);
editor.commit();
}
private void saveVariable(int numberOfTrue){
SharedPreferences sharedPref = this.getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt("key2", numberOfTrue);
editor.commit();
}
private void loadVariable(){
SharedPreferences sharedPref = this.getPreferences(Context.MODE_PRIVATE);
int number = sharedPref.getInt("key2", 0);
tv1.setText(""+number);
numberOfTrue=number;
}
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
switch(buttonView.getId()){
case R.id.cb1:
saveInSp("cb1",isChecked);
if (isChecked == true){
numberOfTrue++;
}
else
{
numberOfTrue--;
}
break;
case R.id.cb2:
saveInSp("cb2",isChecked);
if (isChecked == true){
numberOfTrue++;
}
else
{
numberOfTrue--;
}
break;
case R.id.cb3:
saveInSp("cb3",isChecked);
if (isChecked == true){
numberOfTrue++;
}
else
{
numberOfTrue--;
}
break;
case R.id.cb4:
saveInSp("cb4",isChecked);
if (isChecked == true){
numberOfTrue++;
}
else
{
numberOfTrue--;
}
break;
}
saveVariable(numberOfTrue);
loadVariable();
}
}
This one if definitely wrong.
Intent intent = new Intent(MainActivity.this, FirstActivity.class);
intent.putExtra("number", numberOfTrue);
startActivityForResult(intent,1);
Intent output = new Intent();
output.putExtra("number", numberOfTrue);
setResult(Activity.RESULT_OK, output);
finish();
You need to left only second part of code. Like this:
Intent output = new Intent();
output.putExtra("number", numberOfTrue);
setResult(Activity.RESULT_OK, output);
finish();
And start your MainActivity like this:
Intent intent = new Intent(FirstActivity.this, MainActivity.class);
startActivityForResult(intent, REQUEST_CODE); // This change is important.
And then do this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK && data != null) {
number = getIntent().getExtras().getInt("number");
}
}
This way you'll receive number from MainActivity when it'll be closed. But if you want to read this value on FirstActivity start (without going to MainActivity, you need to store checked number in shared preferences and then get value in onCreate() method of FirstActivity.
Write into SharedPreferences in onActivityResult to insure that only "saved" checks will be saved.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK && data != null) {
number = getIntent().getExtras().getInt("number");
saveNumberToSharedPrefs(number);
}
}
private void saveNumberToSharedPrefs(int num){
SharedPreferences preferences = getSharedPreferences(SHARED_PREFS_NAME, MODE_PRIVATE); //Create and store this instance in onCreate method of activity, or use it like this.
preferences.edit().putInt("NUMBER", num).apply(); // Use constant value for key
}
And then you can load your checked number in onCreate method of FirstActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
....
SharedPreferences preferences = getSharedPreferences(SHARED_PREFS_NAME, MODE_PRIVATE);
number = preferences.getInt("NUMBER", 0);
}
Update
Here you'r trying to get number from intent in onActivityResult. That's wrong, this way you'll always have number = 0 (default value). On activity result doesn't fill data into intent. All your data is in data variable passed in method.
number = getIntent().getExtras().getInt("number");
saveNumberToSharedPrefs(number);
You need to leave only this:
if (requestCode == REQUEST_CODE) { //also you need to check if result is RESULT_OK
number = data.getExtras().getInt("number");
tv2.setText(""+number);
saveNumberToSharedPrefs(number);
}
FirstActivity
Store values :
Intent intent = new Intent(getBaseContext(), Activity.class);
intent.putExtra("ID", sessionId);
startActivity(intent);
SecondActivity
Fetching Values:
String s = getIntent().getStringExtra("ID");
public static final int REQUEST_CODE = 100;
change on FirstActivity.java
b1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent intent = new Intent(FirstActivity.this, MainActivity.class);
startActivityForResult(intent, REQUEST_CODE);
}
});
add onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_CODE) {
Log.d("TAG","------"+data.getExtras().getInt("number"));
int number = data.getExtras().getInt("number");
tv2.setText(""+number);
}
}
}
change on MainActivity.java
b2.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Log.d("TAG","------"+numberOfTrue);
Intent output = new Intent();
output.putExtra("number", numberOfTrue);
setResult(Activity.RESULT_OK, output);
finish();
}
});
I have a 2 activity A and B .
In activity A I start activity B . On activity B I want to do photo and go back to activity A and do next step.
In activity A I have :
Intent intent1 = new Intent(this, CameraActivity.class);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent1, REQUEST_CAMERA);
In activity B I have
buttonClick.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
camera.autoFocus(new Camera.AutoFocusCallback() {
#Override
public void onAutoFocus(boolean success, Camera camera) {
camera.takePicture(shutterCallback, rawCallback, jpegCallback);
startActivity();
}
});
}
});
private void startActivity(){
Intent output = new Intent();
output.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
setResult(REQUEST_CAMERA, output);
finish();
}
And on Activity A I have :
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_FILE) {
onSelectFromGalleryResult(data);
} else if (requestCode == REQUEST_CAMERA) {
onCaptureImageResult(data);
}
}
}
I don't know how on Activity B put fileUri and start good method on activity A
PictureCallback jpegCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
new ImageTask().execute(data);
clearCamera();
}
};
Intent output = new Intent();
output.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
setResult(RESULT_OK, output);//change this
finish();
