I have a custom ListView with BaseAdapter. In this custom ListView when a user clicks on any particular text, it speaks the text but the problem is that when any user clicks on the back button how to stop this text from the BaseAdapter. I know how to stop from an Activity but don't know how to stop from BaseAdapter when the user presses back button. Here is my code:

The main problem is that your TextToSpeech object belongs to your BaseAdapter when it should belong to the parent activity.
Instead of housing it in the adapter and calling speak on it every time the user clicks an item, I would instead house it in the parent activity and use an "interface callback" that sends a message to the parent when the user clicks an item, sending back the string to speak. This callback relationship works the exact same way as the TextToSpeech.OnInitListener callback that you're already using.
Once the TTS belongs to the parent activity, you can use the activity lifecycle functions to control the shutdown of the TTS like normal.
If you study and understand the following, you should be able to merge it into your code and get a working solution:
Make these changes to your custom BaseAdapter:
// Remove the TextToSpeech object from this class.
public class MyBaseAdapter {
// add this interface definition to your adapter
public interface SpeechClickSubscriber {
void stringNeedsToBeSpoken(String verse);
}
// add this property (the subscriber)
private SpeechClickSubscriber speechClickSubscriber;
// *add* this functionality to your adapter's existing constructor
MyBaseAdapter(SpeechClickSubscriber parent) {
speechClickSubscriber = parent;
}
//...
// change this section of code in your getView() method
speakverse.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick (View v){
// change this...
// singleverse(verselist.get(position).toString());
// to this:
speechClickSubscriber.stringNeedsToBeSpoken(verselist.get(position).toString());
}
});
// ...
}
Make these changes to your MainActivity (or whatever your parent activity is):
// add the SpeechClickSubscriber implementation
public class MainActivity extends AppCompatActivity implements MyBaseAdapter.SpeechClickSubscriber, TextToSpeech.OnInitListener {
MyBaseAdapter adapter;
TextToSpeech textToSpeech;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// using app context is better and less error prone.
textToSpeech = new TextToSpeech(getApplicationContext(), this);
}
// *add* this method to this activity (this is the answer to your question)
#Override
protected void onStop() {
super.onStop();
stopTTS();
}
// use this method as your "onStart()" method...
// this will help prevent any user input processing until the tts is initialized.
private void start_Activity_Because_TTS_Has_Initialized() {
adapter = new MyBaseAdapter(this);
}
// *MOVE* this method from your base adapter to this (parent) activity:
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = textToSpeech.setLanguage(Locale.US);
// tts.setPitch(5); // set pitch level
// tts.setSpeechRate(2); // set speech speed rate
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Language is not supported");
} else {
}
} else {
Log.e("TTS", "Initilization Failed");
}
}
// *move* and *rename* this method from your adapter to the parent activity:
// from:
/*
private void singleverse(String text) {
DefaultSettings.speed(context);
textToSpeech.setPitch(DefaultSettings.pitchvalue);

I am completely new to Android Studio and just learned Object-oriented programming. My project requires me to build something on open-source code. I added a new menu item to a menu and want to start another activity once the user clicks the menu item with id: plot. I followed a recipe on the internet but got an error with it. It said 'method call expected' which means Terminal Fragment may be a method. I got confused, as I thought it is a class(an activity). Could anyone give me instructions to start an activity (turn to the next page with a different activity) in this case? What will be the simplest way to do this? Much Appreciated.
I added this in onOptionsItemSelected(MenuItem item).
if (id == R.id.plot){
Intent intent = new Intent(TerminalFragment.this, MainActivity2.class);
startActivity(intent);

Here, TerminalFragment is a fragment, not an activity. And so, instead of using TerminalFragment.this in new Intent(), you should use getActivity().
So, the final code would look something like this:
Intent intent = new Intent(getActivity(), MainActivity2.class);
startActivity(intent);
You can also check this: Intent from Fragment to Activity
I am using sqlite for database. When i add data in ListView. Data added correctly. But when i close app then updated list lost data which i added before. With code Statically added data shows but using app when create reminder then data added successfully in ListView. But when i restart app new data lost after restart app I mean creating reminder delete automatically after restart app.
Even I delete reminders which added by code after restart app all deleted reminders showing in ListView again. But Dynamically added data not show.
Please help me to solve this problem.

I have one recycle list view .In this I have one button .on click list view item button shows.On button click I hit one api to perform action .After performing action ,at the bottom of list automatically one item get repeat. when ever I perform api hit action same time items add at the bottom of list .Like as I perform api hit action 4 times then every time one-one item get add at the bottom of list .

the FolderActivity runs on top of the MainActivty but the voice recognition in MainActivity is still active and I want the voice itself do some manipulation in the FolderActivity
Here's a few suggestions:
Have FolderActivity register a BroadcastReceiver as a listener for a certain Intent. When MainActivity wants to do something in FolderActivity, it can send a broadcast Intent which will be seen by the BroadcastReceiver in FolderActivity, which can then call the appropriate method in the `Activity.
When MainActivity wants to do something in FolderActivity, it can launch FolderActivity again using an Intent with flag Intent.FLAG_ACTIVITY_SINGLE_TOP and some "extra" that describes what FolderActivity should do. In FolderActivity override onNewIntent(), read the passed Intent parameter and use it to determine what method to call in FolderActivity. Because the Activity was launched withIntent.FLAG_ACTIVITY_SINGLE_TOP, Android won't create a new instance of the Activity, it will just callonNewIntent()` on the existing instance.
Have FolderActivity set a public static variable of type Activity to a reference to itself in onCreate(). MainActivity can then call a method on FolderActivity by doing something like FolderActivity.activityReference.doSomething()
Method 3 is not the preferred method, since you need to make sure that you set the public static variable to null in FolderActivity.onDestroy() and there are other concerns (timing issues, memory leaks, etc.) that need to be dealt with properly.
NOTE: You probably don't want to call onOptionsItemSelected() directly. This method is called by the Android framework when an options item is selected by the user. You should call directly the method that actually does something, not this framework callback method.

The issue is, I have tried to log the results of the EditText, however I never see that in the logs. What is going on here? I can't work out why I'm never seeing "Text value is " + queryText in the logs.
The problem is you initialize the String value queryText in the event of the screen being created (onCreate()) and not when you actually type in values (after screen creation & dynamic activity on the screen).
This is why the following would work
#Override
public void onClick(View view) {
queryText = (queryEditText.getText().toString());
Log.i(LogConstants.LOG, "Text value is " + queryText);
if (queryText.equals("")) {
Toast.makeText(context, "You did not enter a query", Toast.LENGTH_SHORT).show();
} else {
new SearchAsyncTask().execute();
}
}
Change
Log.i(LogConstants.LOG, "Text value is " + queryText);
to
Log.i(LogConstants.LOG, "Text value is " + queryEditText.getText().toString());
Move
queryText = (queryEditText.getText().toString());
inside the onClick
queryButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
queryText = (queryEditText.getText().toString());
Log.i(LogConstants.LOG, "Text value is " + queryText);
if ("".equals(queryText)) {
Toast.makeText(context, "You did not enter a query", Toast.LENGTH_SHORT).show();
} else {
new SearchAsyncTask().execute();
}
}
});
