What is the better way to handle mutiple intents in android?

What is the better way to handle mutiple intents in android? - java

We come across the following code or something similar in Android or Java many times. This code seems like containing repetitions and this is not a good practice at all. There must be some better way to do this. is there any shorter code to achieve this?
Intent intent=null;
switch (v.getId()) {
case R.id.details:
intent = new Intent(this, DetailsActivity.class);
break;
case R.id.apply:
intent = new Intent(this, ApplyActivity.class);
break;
case R.id.edit:
intent = new Intent(this, EditActivity.class);
break;
case R.id.upload:
intent = new Intent(this, UploadActivity.class);
break;
case R.id.call:
intent = new Intent(this, CallActivity.class);
break;
}
startActivity(intent);

Make a table of ids to activity classes in a static initializer or constructor:
HashMap<Integer, Class<?>> map = new HashMap<>();
map.put(R.id.foo, Foo.class); // repeat for each id/class pair
Then use the map instead of a switch:
startActivity(new Intent(this), map.get(v.getId()));

As I commented use setClass method instead. Do like this.
Set your Activity classname to button tag and get this tag on button click.
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:tag="YourActivityName"
/>
Java Code
String classname = (String) textView.getTag();
intent.setClassName(getPackageName().toString(), classname)
startActivity(intent);

Yes Ofcourse. This is not a good practise at all. Try to achieve generalization.
Below is what I put into practice.
Just a think, Why I would write the code again, when it is already written..!!
Thinking that way,
Put all the common code in to a common class
Extend that class
Use its members
Create a class, say BaseAppCompatActivity.java as below:
public abstract class BaseAppCompatActivity extends AppCompatActivity {
private ProgressDialog mProgressDialog;
private Toolbar mToolbar;
private TabLayout mTabLayout;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutResourceId());
initiateViews();
}
protected abstract int getLayoutResourceId();
protected abstract void initiateViews();
public void setHasToolBar() {
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
}
public Toolbar getToolBar() {
return mToolbar;
}
public void setHasTabLayout() {
mTabLayout = (TabLayout) findViewById(R.id.tabLayout);
}
public TabLayout getTabLayout() {
return mTabLayout;
}
public void showProgressDialog() {
showProgressDialog("Please Wait ...");
}
public void showProgressDialog(String message) {
// progress bar not null and is visible, so set the title
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.setMessage(message);
}
// create new progress bar
else {
mProgressDialog = ProgressDialog.show(this, "Loading", message, true, false);
}
}
public void hideProgressDialog() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.dismiss();
}
}
public void showAlertDialog(String message) {
AlertDialog alertDialog = new AlertDialog.Builder(this)
.setNeutralButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.dismiss();
}
})
.create();
alertDialog.setMessage(message);
alertDialog.show();
}
public void showToast(String message) {
Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
}
public void logInformation(Class tag, String description) {
Log.i(tag.getName(), description);
}
public void logError(Class tag, String description) {
Log.e(tag.getName(), description);
}
public void logDebug(Class tag, String description) {
Log.d(tag.getName(), description);
}
public void launchActivity(Class<? extends Activity> cls, Bundle bundle, int code) {
Intent intent = new Intent();
if (bundle != null)
intent.putExtras(bundle);
intent.setClass(activity, cls);
if (code == -1)
startActivity(intent);
else
startActivityForResult(intent, code);
}
public void loadFragment(Class fragmentClass, boolean addToBackStack) {
Fragment fragment = null;
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
if (fragment != null) {
if (addToBackStack) {
getSupportFragmentManager()
.beginTransaction()
.addToBackStack(fragmentClass.getSimpleName())
.replace(R.id.frameLayout, fragment, fragmentClass.getSimpleName())
.commit();
} else {
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.frameLayout, fragment, fragmentClass.getSimpleName())
.commit();
}
}
}
}
And after that, extend all your activities to this BaseAppCompatActivity class.
Then, in your code in activity is cut down to just
launchActivity(Activity2.class, null, -1);

You can set tag equal your activity :
<Button
android:id="#+id/btn1"
android:tag="DetailsActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dnt want this text" />
<Button
android:id="#+id/btn2"
android:tag="ApplyActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dnt want this text" />
<Button
android:id="#+id/btn3"
android:tag="EditActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dnt want this text" />
<Button
android:id="#+id/btn4"
android:tag="EditActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dnt want this text" />
<Button
android:id="#+id/btn5"
android:tag="DetailsActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dnt want this text" />
<Button
android:id="#+id/btn6"
android:tag="CallActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dnt want this text" />
Java code this : Your package name :com.example.pkg1
Intent intent = new Intent();
intent.setClassName("com.example.pkg1", "com.example.pkg1."+v.getTag() );
startActivity(intent);

How can I change the TextView's content by swiping horizontally?

I have an audiobook app that I'm currently working on. If the book has audio, the controller will be shown. If not, it'll only show the text. I want to switch the chapters just by swiping at the text. I'm currently using a RelativeLayout and the text is wrapped in a ScrollView. I read that I should use ViewPager. But I was wondering if I could just keep using the RelativeLayout and ScrollView.

Thank you in advance !

You can detect gestures on any View by attaching an onTouchListener to it.
In your case however, you are trying to detect swiping gestures, therefore the best solution is to create a gesture detector class by extending an onTouchListener like in this tutorial (step 4):
https://www.tutorialspoint.com/how-to-handle-right-to-left-and-left-to-right-swipe-gestures-on-android
After doing this, you can easily attach the swipe-detector class to any of your views as:
textView.setOnTouchListener(new OnSwipeTouchListener(MainActivity.this) {
#Override
public void onSwipeLeft() {
super.onSwipeLeft();
// do something
}
#Override
public void onSwipeRight() {
super.onSwipeRight();
// do something
}
});

Have you tried to add and OnSwipeTouchListener like here https://stackoverflow.com/a/12938787/4330467?
Relativelayout should not be the issue

How to save all data inputed in fragments into database on click of completed using material stepper library

I am using this library - https://github.com/stepstone-tech/android-material-stepper to build a step by step registration system where users will fill each field one by one before finally saving users data into the database using a php script via JSON.
I have 2 problems.
1. After filling the data, I dont kow how to save the data that has been inputed into the database.
2 How to validate each data been inputed individually onClick of 'NEXT' button. (Although, number 1 is much more important for now, but if someome could help me out with both, GREAT!.)
I have done this with the use of just one activity and it works fine.
One of the fragment. 6 of them (They are all similar)
public class EmailRegisterFragment extends Fragment implements Step {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_email_register, container, false);
//initialize your UI
return v;
}
#Override
public VerificationError verifyStep() {
//return null if the user can go to the next step, create a new VerificationError instance otherwise
return null;
}
#Override
public void onSelected() {
//update UI when selected
}
#Override
public void onError(#NonNull VerificationError error) {
//handle error inside of the fragment, e.g. show error on EditText
}
}
One of the fragementLayout (They are all similar)

How do use this same logic for the fragments??

this might be late but i think it would help to others. So for sure you can validate/Insert or whatever you want to do with your inputs on Next button click before going to next step, This is how you can do it in Kotlin
// To be somewhere inside your Step
override fun verifyStep(): VerificationError? {
if (validateStep()){
return null
}
else
VerificationError("Any error message")
}
Now here validateStep will be a function that returns True or false depending upon your needs. Here is a simple example of a validateStep() function. Here you can do anything like insertion or validation etc.
private fun validateStep(): Boolean {
var isValid = true
val name = binding.etCustomerName.text.toString()
val email = binding.etCustomerEmail.text.toString()
if (name.isEmpty()) {
isValid = false
}
if (email.isEmpty()) {
isValid = false
} else if (!Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
isValid = false
}
return isValid
}
Do let me know if it helps anyone. Happy coding :)

Share multiple messages with same intent chooser in my app

I have this code
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
sharingIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
else
sharingIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_DOCUMENT);
String activityTitle = cellsList.get(position).getTitle();
sharingIntent.putExtra(Intent.EXTRA_SUBJECT, activityTitle);
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri);
sharingIntent.setType("image/*");
sharingIntent.setPackage("com.whatsapp");
sharingIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
sharingIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
Intent chooser = Intent.createChooser(sharingIntent,getResources().getString(R.string.share_using));
getActivity().startActivity(chooser);
And I want to share another message that contain text and image to the same chooser app.
Do u have any idea on how to solve the problem?

You can use a ShareActionProvider. In the following sample, I'm using one tied to a MenuItem in the Toolbar, but it's also possible to use them with e.g. a Button.
main_menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/menu_item_share"
app:showAsAction="ifRoom"
android:title="Share"
app:actionProviderClass=
"android.support.v7.widget.ShareActionProvider" />
</menu>
activity_main.xml
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.sharing.datasender.MainActivity">
<TextView
android:id="#+id/view2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center_vertical"
android:text="Send data once more"
/>
</FrameLayout>
MainActivity.java
public class MainActivity extends AppCompatActivity
{
private ShareActionProvider shareActionProvider;
private Intent shareIntent;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
View view = findViewById(R.id.view2);
view.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
sendDataOnceMore();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.main_menu, menu);
MenuItem item = menu.findItem(R.id.menu_item_share);
shareActionProvider = (ShareActionProvider)MenuItemCompat.getActionProvider(item);
setShareIntent(getShareIntent());
shareActionProvider.setOnShareTargetSelectedListener(new ShareActionProvider.OnShareTargetSelectedListener()
{
#Override
public boolean onShareTargetSelected(ShareActionProvider shareActionProvider, Intent intent)
{
ComponentName component = intent.getComponent();
shareIntent = intent;
String className = null;
if (component != null)
{
className = component.getClassName();
}
Log.d("TEST", "onShareTargetSelected: *" + className + "*");
return false;
}
});
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
int id = item.getItemId();
switch (id)
{
case R.id.menu_item_share:
Intent intent = getShareIntent();
setShareIntent(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
private Intent getShareIntent()
{
Intent sharingIntent = new Intent();
sharingIntent.setAction(Intent.ACTION_SEND);
sharingIntent.putExtra(Intent.EXTRA_SUBJECT, "This is my text to send.");
Uri uri = Uri.parse(IMAGE_PATH);
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri);
sharingIntent.setType("image/*");
sharingIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
sharingIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
return sharingIntent;
}
private void sendDataOnceMore()
{
if (shareIntent != null)
{
Intent sendIntent = new Intent();
try
{
sendIntent.fillIn(shareIntent, Intent.FILL_IN_COMPONENT + Intent.FILL_IN_ACTION + Intent.FILL_IN_CATEGORIES + Intent.FILL_IN_PACKAGE);
sendIntent.putExtra(Intent.EXTRA_TEXT, "And another thing...");
sendIntent.setType("text/plain");
sendIntent.setAction(Intent.ACTION_SEND);
startActivity(sendIntent);
}
catch (Exception e)
{
e.printStackTrace();
Toast.makeText(this, "Boooom!", Toast.LENGTH_LONG).show();
return;
}
}
else
{
Toast.makeText(this, "No Go :(", Toast.LENGTH_LONG).show();
return;
}
}
// Call in onCreateOptionsMenu() or the MenuItem will not be clickable!
// Call later to update the share Intent
private void setShareIntent(Intent shareIntent)
{
if (shareActionProvider != null)
{
shareActionProvider.setShareIntent(shareIntent);
}
}
}
Remember to make sure that sendIntent.resolveActivity() != null if you're using this much later - the other app may have been uninstalled in the meantime!

I would avoid saving the token in the shared preferences and rather try to perform a Silent Sign In as described here: http://android-developers.blogspot.de/2015/12/api-updates-for-sign-in-with-google.html
This has the advantage to let you verify if the user is still logged in and eventually let you prompt him to request to re-login.
here some code (basically adapted from the example in the link):
public void silentLogin() {
OptionalPendingResult<GoogleSignInResult> pendingResult = Auth.GoogleSignInApi.silentSignIn(googleApiClient);
if (pendingResult != null) {
handleGooglePendingResult(pendingResult);
} else {
//no result from silent login. Possibly display the login page again
}
}
private void handleGooglePendingResult(OptionalPendingResult<GoogleSignInResult> pendingResult) {
if (pendingResult.isDone()) {
// There's immediate result available.
GoogleSignInResult signInResult = pendingResult.get();
onSilentSignInCompleted(signInResult);
} else {
// There's no immediate result ready, waits for the async callback.
pendingResult.setResultCallback(new ResultCallback<GoogleSignInResult>() {
#Override
public void onResult(#NonNull GoogleSignInResult signInResult) {
onSilentSignInCompleted(signInResult, callback);
}
});
}
}
private void onSilentSignInCompleted(GoogleSignInResult signInResult) {
GoogleSignInAccount signInAccount = signInResult.getSignInAccount();
if (signInAccount != null) {
// you have a valid sign in account. Skip the login.
} else {
// you don't have a valid sign in account. Eventually display the login page again
}
}

You can try this:
After user login success then you can save id token to SharedPreferences by call method getIdToken() of GoogleSignInAccount. And when user reopen you can check id token is exiting then ignore login screen.
private void getSignInResult(GoogleSignInResult result) {
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
String id_token = acct.getIdToken(); //add this code here to save it by use SharedPreferences
TextView user_name= (TextView)findViewById(R.id.userName);
TextView email_id= (TextView)findViewById(R.id.emailId);
user_name.setText("UserName: "+ acct.getDisplayName());
email_id.setText("Email Id: " + acct.getEmail());
updateUI(true);
progress_dialog.dismiss();
} else {
// Signed out, show unauthenticated UI.
updateUI(false);
}
}
//save user login state id_token
private void saveLoginState(String id_token){
SharedPreferences sharedpreferences = getSharedPreferences("YOUR_PREFERENCE_NAME", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString("GG_LOGED", id_token);
editor.commit();
}

After the user login you can use this code to store the data in SharedPreference
SharedPreferences sharedPreferences = getSharedPreferences("APP", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("isLogin", true);
editor.putString("name", //Name);
editor.putString("e_mail",//Email);
editor.putString("ID", //ID);
editor.commit();
And in the splash screen you can do like this
boolean isLoggedIn = sharedPreferences.getBoolean("isLogin", false);
Here isLoggedIn is the value whether the user is logged in or not status. You need to handle this in SplashScreen and proceed according to that.

(EditText)Android Contact list getting phone number

I'm new to Android development. I have used ;
I type the number in the EditText, Now i want to get the contact number from my contact list. can someone pls help me to fix this?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText pnumber= (EditText) findViewById(R.id.editTextPnumber);
final EditText gsms= (EditText) findViewById(R.id.editTextSMS);
Button sendsms= (Button) findViewById(R.id.buttonSend);
sendsms.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String gPhone= pnumber.getText().toString();
String gSMS= gsms.getText().toString();
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(gPhone, null, gSMS, null, null);
Toast.makeText(getApplicationContext(), "SMS Sent ! ", Toast.LENGTH_LONG).show();
finish();
} catch (Exception e) {
// TODO: handle exception
Toast.makeText(getApplicationContext(), "PLS Enter Again ! ", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});

This is a simple trick. I hope you would be able to fix this to your code easily.
You can put a button (SMS) to its setOnClickListener you can use this.
public void onClick(View v) {
// TODO Auto-generated method stub
try {
Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.putExtra("sms_body", "default content");
sendIntent.setType("vnd.android-dir/mms-sms");
startActivity(sendIntent);
} catch (Exception e) {
// TODO: handle exception
Toast.makeText(getApplicationContext(),
"PLS Enter Again ! ", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});

If you means that you want wrap input number with matched contact name from your contacts on the device?
For that you want
1) ContactProvider http://developer.android.com/guide/topics/providers/contacts-provider.html
2) AutoComplete http://developer.android.com/guide/topics/ui/controls/text.html#AutoComplete
3) If you want no one number, you could youse some chips. (EditText, Spanned) https://github.com/nichtemna/ChipsEditText#mychipsedittext, https://github.com/kpbird/chips-edittext-library

// try this way here i gave sample or demo code you modify as per your requirement.

What is the better way to handle mutiple intents in android? - java

Make a table of ids to activity classes in a static initializer or constructor: HashMap<Integer, Class<?>> map = new HashMap<>(); map.put(R.id.foo, Foo.class); // repeat for each id/class pair Then use the map instead of a switch: startActivity(new Intent(this), map.get(v.getId()));
