在父代或祖先中找不到onClick_leave（View）的方法

Question

我有三個textviews in Activity並確認哪個textview被按下，我正在使用下面的方法並相應地設置了微調器的值，但活動並未識別此方法。 我嘗試了很多方法，但沒有收到錯誤。需要幫忙 當我textview應用點擊獲取墜毀，日誌顯示此錯誤

java.lang.IllegalStateException：在 Android的父母或祖先上下文找不到方法 onClick_leave（查看）：onclick屬性定義在視圖類 android.support.v7.widget.AppCompatTextView ID爲 'PL'

這裏是我的代碼：

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

您應該使用setOnClickListener。

註冊一個回調，當點擊這個視圖時被調用。如果這個 視圖不可點擊，它將變爲可點擊。

 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 
     } 
    }
