Verify.java

package com.example.myapp.appfirst; 

import android.app.Activity; 
import android.content.Context; 
import android.widget.Button; 
import android.view.View.OnClickListener; 
import android.view.View; 
import android.widget.EditText; 
. 
. 
. 

public class Verify extends Activity{ 
    public Button bt; 
    public EditText digits; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_verify); 
     this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); //App with fullscreen 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     bt = (Button) findViewById(R.id.verification); 
     digits = (EditText) findViewById(R.id.otp); 
      getdata(); //This function sends otp to the phone and sets countdown timer for OTP verification 
     Log.d("oncreate","Now going to buttonVerify()"); 
     buttonVerify(); 
    } 

    public void buttonVerify() { 
     Log.d("Button","Entered into buttonVerify"); 
     bt.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Log.d("Button clicked","yaah!!"); 
       Toast.makeText(getBaseContext(),"It's working",Toast.LENGTH_SHORT).show(); 
. 
. 
. 
} 
     }); 
    } 
. 
. 
. 

Le message Logcat "Bouton cliquée/yaah !!" n'a jamais été affiché et le message toast dans la méthode onClick n'est jamais affiché. Le bouton ne clique pas du tout. J'ai parcouru tous les codes et questions sur stackoverflow et je ne sais pas ce qui ne va pas avec mon code alors que dans d'autres applications que j'ai créées plus tôt, le même code fonctionnait parfaitement.

Answer 1

peut vous this.requestWindowFeature(Window.FEATURE_NO_TITLE); ci-dessus à la ligne setContentView(R.layout.test);
