Как я могу поставить OnClickListener на фон?

Question

* Привет, у меня есть приложение для фонарика, но я не могу запустить его, idk, почему, я думаю, что это OnClickListener в фоновом режиме. Возможно, это неправильно, или idk, я новичок, извините D: Logcat: enter link description here (Ничего важного, я думаю) У меня есть другой FlashLight и фон OnClickListener - разница между этими приложениями .. Но .. Как я могу добавить, что, когда я нажимаю кнопку LAYOUT или BACKGROUND (то же самое), включите флеш? : |

Вот код: *

public class MainActivity extends Activity { 




public boolean onKeyDown(int keyCode, KeyEvent event) { 
    if (keyCode == KeyEvent.KEYCODE_BACK) { 
     exitByBackKey(); 

     //moveTaskToBack(false); 

     return true; 
    } 
    return super.onKeyDown(keyCode, event); 
} 

protected void exitByBackKey() { 

    AlertDialog alertbox = new AlertDialog.Builder(this) 
    .setMessage("Do you want to Exit?") 
    .setPositiveButton("Yes", new DialogInterface.OnClickListener() { 

     // do something when the button is clicked 
     public void onClick(DialogInterface arg0, int arg1) { 

      finish(); 
      //close(); 


     } 
    }) 

    .setNeutralButton("Rate us!", new DialogInterface.OnClickListener() { 

     // do something when the button is clicked 
     public void onClick(DialogInterface arg0, int arg1) { 

      { 
       Uri uri = Uri.parse("market://details?id=" + getPackageName()); 
       Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri); 
       try { 
        startActivity(goToMarket); 
       } catch (ActivityNotFoundException e) { 
        Toast.makeText(getApplicationContext(), "Couldn´t launch Google Play", 
          Toast.LENGTH_LONG).show(); 
       } 
      } 


     } 
    }) 

    .setNegativeButton("No", new DialogInterface.OnClickListener() { 

     // do something when the button is clicked 
     public void onClick(DialogInterface arg0, int arg1) { 
         }

Answer 1

Внутри вашего onCreate, вы можете иметь компоновщика onClickListener на вашем внешней макета следующим образом:

RelativeLayout layout=(RelativeLayout)findViewById(R.id.yourRelativeLayout); 
layout.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v){ 
    } 
}); 

Возможно, вам понадобится добавить android:clickable = true от xml или setClickable(true) от кода.
