How to pass data from return activity to dialog in previous activity?

Visitor Details
I have a dialog in Visitor Activity. When I click on the icon, it will redirect to Camera Activity. Then when click Confirm button in Camera Activity, it will send the intent back to previous Activity which is Visitor Activity. The problem is how should I pass the intent result from Camera Activity back to the dialog in Visitor Activity. The intent data should be placed in the Pass No Edit Text. I'm using material dialog without any Fragment that attached to that dialog. It all placed in Visitor Activity. Can someone please help me? Thank you!
private void checkin()
{
final MaterialDialog dialog = new MaterialDialog.Builder(VisitorDetailActivity.this)
.customView(R.layout.sample,false)
.build();
View view = dialog.getCustomView();
final EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
final EditText etVehicleNo = (EditText) view.findViewById(R.id.etVehicleNo);
final ImageView ivScanCode = (ImageView) view.findViewById(R.id.ivScanCode);
final TextView tvCancel = (TextView) view.findViewById(R.id.tvCancel);
final TextView tvSubmit = (TextView) view.findViewById(R.id.tvSubmit);
etVehicleNo.setText(model.getFldVehicleNo());
if(barCode != null)
{
etPassNo.setText(barCode);
}
ivScanCode.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//Toast.makeText(VisitorDetailActivity.this, "Bar code scanner", Toast.LENGTH_SHORT).show();
Intent i = new Intent(VisitorDetailActivity.this, ScanCodeActivity.class);
startActivityForResult(i,97);
}
});
tvCancel.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
dialog.dismiss();
}
});
tvSubmit.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
if(etPassNo.getText().toString().trim().isEmpty())
{
Toast.makeText(VisitorDetailActivity.this, "Pass No is required", Toast.LENGTH_SHORT).show();
return;
}
if(selImage == null)
{
proceedCheckin(etPassNo.getText().toString(), etVehicleNo.getText().toString());
}
else
{
proceedCheckinImage(etPassNo.getText().toString(), etVehicleNo.getText().toString());
}
}
});
dialog.show();
}
#Override

{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 98 && resultCode == RESULT_OK)
{
selImage = data.getStringExtra("photo");
Glide.with(VisitorDetailActivity.this).load(selImage).into(iDrivingLicense);
}

First you need to take the view object globally out of that checkIn methoed
View view;
view = dialog.getCustomView();
final EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
Now under your onActivityResult method, as i can see you already getting the barcode there, so just initiate the EditText object again on that same simply set the data in it.
barCode = data.getStringExtra("barCode");
EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
etPassNo.setText(barCode);
Let me know if that works.

you can do it using interface
public interface OnBarcodeSelect{
void onBarcodeSelected(String barcode);}
OnBarcodeSelect onBarcodeSelect;
private void checkin()
{
final MaterialDialog dialog = new MaterialDialog.Builder(VisitorDetailActivity.this)
.customView(R.layout.sample,false)
.build();
View view = dialog.getCustomView();
final EditText etPassNo = (EditText) view.findViewById(R.id.etPassNo);
final EditText etVehicleNo = (EditText) view.findViewById(R.id.etVehicleNo);
final ImageView ivScanCode = (ImageView) view.findViewById(R.id.ivScanCode);
final TextView tvCancel = (TextView) view.findViewById(R.id.tvCancel);
final TextView tvSubmit = (TextView) view.findViewById(R.id.tvSubmit);
etVehicleNo.setText(model.getFldVehicleNo());
if(barCode != null)
{
etPassNo.setText(barCode);
}
ivScanCode.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//Toast.makeText(VisitorDetailActivity.this, "Bar code scanner", Toast.LENGTH_SHORT).show();
Intent i = new Intent(VisitorDetailActivity.this, ScanCodeActivity.class);
onBarcodeSelect = new OnBarcodeSelect() {
#Override
public void onBarcodeSelected(String barcode) {
//handle barcode here
etPassNo.setText(barcode);
}
}
startActivityForResult(i,97);
}
});
tvCancel.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
dialog.dismiss();
}
});
tvSubmit.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
if(etPassNo.getText().toString().trim().isEmpty())
{
Toast.makeText(VisitorDetailActivity.this, "Pass No is required", Toast.LENGTH_SHORT).show();
return;
}
if(selImage == null)
{
proceedCheckin(etPassNo.getText().toString(), etVehicleNo.getText().toString());
}
else
{
proceedCheckinImage(etPassNo.getText().toString(), etVehicleNo.getText().toString());
}
}
});
dialog.show();
}
#Override

status bar goes black while showing bottom sheet dialog

how do I prevention the status bar from loosing it's color while a bottom sheet is showing up?
I use a bottom sheet view with custom layout.
tried modify the style of the dialog but still no luck
here is my code
if (position == 1) {
View modalbottomsheet = getActivity().getLayoutInflater().inflate(R.layout.others_sheet, null);
dialog = new BottomSheetDialog(getActivity());
dialog.setContentView(modalbottomsheet);
dialog.setCanceledOnTouchOutside(true);
dialog.setCancelable(true);
dialog.show();
contact_num = (EditText) modalbottomsheet.findViewById(editText);
choose_contact = (Button) modalbottomsheet.findViewById(choose);
choose_contact.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (v.getId() == choose_contact.getId()) {
Intent intent = new Intent(Intent.ACTION_PICK,
ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, REQUEST_CODE);
}
}
});
hidetext = (EditText) modalbottomsheet.findViewById(R.id.hidetext);
recharge_btn = (Button) modalbottomsheet.findViewById(R.id.rechargeothers_btn);
recharge_btn.setOnClickListener(new View.OnClickListener() {

});
}

Error while transfer data from 2nd activity

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();
}
});

Sending data from child activity to the main one

After trying lot of things found here, nothing worked.
To make it simple :
I have a main activity with a button.
I have a "child" activity with 2 text fields and a button.
When I click the main activity button, the child activity opens (it works). Then I put some text to the two text fields and when I click the button I want the data from the text fields to be transfered to the main activity, and I can't get this working.
Here is my main activity code
public class MainMenu extends AppCompatActivity {
Button btnAddBib;
public final static int REQUEST_CODE_B = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
btnAddBib = (Button)findViewById(R.id.btnAddBib);
btnAddBib.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(v.getContext(), MainActivity.class);
startActivityForResult(myIntent,REQUEST_CODE_B);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode) {
case REQUEST_CODE_B:
String Qte = data.getStringExtra("qte");
String Time = data.getStringExtra("time");
if (Qte != null && !Qte.isEmpty() && Time != null && !Time.isEmpty()) {
final SQLiteDatabase dbBib;
dbBib = openOrCreateDatabase("bibi", Context.MODE_PRIVATE, null);
dbBib.execSQL("CREATE TABLE IF NOT EXISTS bibi(time VARCHAR, qte VARCHAR);");
dbBib.execSQL("INSERT INTO bibi VALUES ('" + Time + "','" +
Qte + "')");
Toast.makeText(getApplicationContext(), "Bibi bien enregistré",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Fail get extraData",
Toast.LENGTH_LONG).show();
}
break;
}
}
And the child activity code :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ajouter_bibi);
btnValideBib = (Button)findViewById(R.id.btnValideBib);
btnValideBib.setBackgroundResource(R.drawable.logo_biberon);
txtTime = (EditText)findViewById(R.id.txtTime);
txtQte = (EditText)findViewById(R.id.txtQte);
Calendar c = Calendar.getInstance();
int hh = c.get(Calendar.HOUR_OF_DAY);
int mm = c.get(Calendar.MINUTE);
txtTime.setText(hh + ":" + mm);
btnValideBib.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent backIntent = new Intent();
backIntent.putExtra("qte", txtQte.getText());
backIntent.putExtra("time", txtTime.getText());
setResult(RESULT_OK, backIntent);
finish();
}
});
The problem :
In the main activity, when I want to get back my Extra Strings I have null fields.
String Qte = data.getStringExtra("qte");
String Time = data.getStringExtra("time");
What is wrong with it ?
Thanks!

Change the code :
backIntent.putExtra("qte", txtQte.getText());
backIntent.putExtra("time", txtTime.getText());
to below code:
backIntent.putExtra("qte", txtQte.getText().toString()); //append .toString() method
backIntent.putExtra("time", txtTime.getText().toString());

Replace the original image on a new image in android application

In this MainActivity java class on Android Application Project I can't replace the original image given by the system with the one different selected from the photo gallery of smartphone.
When I select the one different photo I have always the original image.
public class MainActivity extends Activity implements OnClickListener {
Button uploadButton, btnselectpic;
ImageView imageview;
private ProgressDialog dialog = null;
private String imagepath = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
uploadButton = (Button) findViewById(R.id.uploadButton);
btnselectpic = (Button) findViewById(R.id.btnselectpic);
imageview = (ImageView) findViewById(R.id.imageview);
btnselectpic.setOnClickListener(this);
uploadButton.setOnClickListener(this);
#Override
public void onClick(View arg0) {
if (arg0 == btnselectpic) {
selectImage();
} else if (arg0 == uploadButton) {
dialog = ProgressDialog.show(MainActivity.this, "",
"Uploading file...", true);
messageText.setText("uploading started.....");
new Thread(new Runnable() {
public void run() {
}
}).start();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && requestCode == 2 && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
imagepath = getPath(selectedImageUri);
Bitmap bitmap = BitmapFactory.decodeFile(imagepath);
imageview.setImageBitmap(bitmap);
messageText.setText("Uploading file path:" + imagepath);
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri, projection, null, null,
null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
private void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery",
"Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo")) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment
.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
} else if (options[item].equals("Choose from Gallery")) {
Intent intent = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}

The problem is that your onActivityResult() will never do anything.
You start this method off with:
if (requestCode == 1 && requestCode == 2 && resultCode == RESULT_OK) {
// ...
}
requestCode cannot be both 1 and 2, so this conditional will always be false.
You are likely looking for something more like this:
if ((requestCode == 1 && resultCode == RESULT_OK) ||
(requestCode == 2 && resultCode == RESULT_OK)) {
// ...
}
