Question

I have a dialog in an Android app that I don’t want the user to be able to cancel. Using .setCancelable(false) disables the back button, but pressing the search button still cancels the dialog. I saw this question which told me that I should include

public boolean onSearchRequested() {
    return false;
}

But I’m still able to cancel the dialog with the search button. Here’s my code:

public class TestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
        public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        showDialog(0);
    }

    public boolean onSearchRequested() {
        return false;
    }

    protected Dialog onCreateDialog(int id) {
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage("Message")
               .setCancelable(false)
               .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                       // nothing
                   }
               });
         return builder.create();
    }
}

@Benh You need this code to set for your Key Listener for Dialog

   builder.setOnKeyListener(keylistener);

Add Below code in your Activity Class

  OnKeyListener keylistener=new DialogInterface.OnKeyListener() {
    @Override
    public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_SEARCH && event.getRepeatCount() == 0) {
            return true; //we stop begin cancel of dialog or Progressbar
        }
        return false; 
    }
}; 

try this above thing in your dialog hope that will work for you.
