View.setOnClickListener

  • interface View.OnClickListener
    • メソッド:abstract void onClick(View v)
    final Button button = (Button) findViewById(R.id.button_id);
         button.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Perform action on click
             }
         });

XMLレイアウトでの定義 (android:onClick)

  • However, instead of applying an OnClickListener to the button in your activity, you can assign a method to your button in the XML layout, using the android:onClick attribute. For example: 
     <Button
     android:layout_height="wrap_content"
     android:layout_width="wrap_content"
     android:text="@string/self_destruct"
     android:onClick="selfDestruct" />
  • In order for this to work, the method must be public and accept a View as its only parameter. For example: 
     public void selfDestruct(View view) {
     // Kabloey
 }
