method setOnKeyListener的问题

      写练习的时候,碰到了一个问题:The method setOnKeyListener(View.OnKeyListener) in the type View is not applicable for the arguments (new OnKeyListener(){})

      源代码如下:

myEdit02.setOnKeyListener(new OnKeyListener() {@Overridepublic boolean onKey(View v, int keyCode, KeyEvent event) {myEdit02.setText("");return false;}});

      出现了上述错误,这里修改代码为:

myEdit02.setOnKeyListener(new EditText.OnKeyListener() {@Overridepublic boolean onKey(View v, int keyCode, KeyEvent event) {myEdit02.setText("");return false;}});
