Methode onClick_leave (View) in einem Eltern- oder Vorfahren

Question

Ich habe drei textviews in Activity und zu erkennen, welche textview gedrückt wird, verwende ich unten Methode und Einstellung spinner Wert entsprechend, aber Aktivität erkennt diese Methode nicht. Ich habe viele Möglichkeiten ausprobiert, aber nicht den Fehler bekommen. wird abgestürzt braucht Hilfe, wenn ich auf textview Anwendung klicken und

java.lang.IllegalStateException zeigt diesen Fehler protokollieren: Konnte nicht Methode onClick_leave (View) in einem Elternteil oder einem Vorfahren Kontext für Android finden: onClick definiert Attribut auf Ansichtsklasse android.support.v7.widget.AppCompatTextView mit id 'pl'

Hier ist mein Code:

public void onClick_leave(View v) { 
     if (v.getId() == R.id.cl) { 
      Intent intent = new Intent(getActivity(), ApplyLeave.class); 
      int leave = 0; 
      intent.putExtra("leave", leave); 
      startActivity(intent); 


     } else if (v.getId() == R.id.pl) { 
      Intent intent = new Intent(getActivity(), ApplyLeave.class); 
      int leave = 1; 
      intent.putExtra("leave", leave); 
      startActivity(intent); 


     } else if (v.getId() == R.id.sl) { 
      Intent intent = new Intent(getActivity(), ApplyLeave.class); 
      int leave = 2; 
      intent.putExtra("leave", leave); 

      startActivity(intent); 
     } else if (v.getId() == R.id.edit_menu) { 
      Intent intent = new Intent(getActivity(), ApplyLeave.class); 
      startActivity(intent); 

     } 
    }

Answer 1

sollten Sie setOnClickListener verwenden.

Registrieren Sie einen Rückruf, der aufgerufen werden soll, wenn auf diese Ansicht geklickt wird. Wenn diese Ansicht nicht anklickbar ist, wird sie anklickbar.

 firstButtonOBJ = (Button) findViewById(R.id.buttonOne); //Global 
     firstButtonOBJ.setOnClickListener(this); 
     secondButtonOBJ = (Button) findViewById(R.id.buttonTwo); 
     secondButtonOBJ.setOnClickListener(this); 


    // onClick is called when a view has been clicked. 
    @Override 
    public void onClick(View v) 
    { 
    // Parameter v stands for the view that was clicked. 

     // getId() returns this view's identifier. 
     if(v.getId() == R.id.buttonOne) 
     { 
      // Your Work 
     } 
     else if(v.getId() == R.id.buttonTwo) 
     { 
      // Your Work 
     } 
    }
