匿名android.view.View.OnLongClickListener

Question

Hbutton.setOnClickListener(
    new Button.OnLongClickListener(){
        public boolean onLongClick(View v){
            TextView Htext = (TextView) findViewById(R.id.Htext);
            Htext.setText("Hunny");
            return true;
        }
    }
);

这段代码有什么问题？？它会给出一个错误

(anonymous android.view.View.OnLongClickListener)

Answer 1

您必须设置onLongClickListener：

Hbutton.setOnLongClickListener(
        new Button.OnLongClickListener(){
             public boolean onLongClick(View v){
                TextView Htext = (TextView) findViewById(R.id.Htext);
                Htext.setText("Hunny");
                return true;
            }
        }

);

Answer 2

试试这种方式，

Button Hbutton = (Button) findViewById(R.id.YOUR_BUTTON_ID);

Hbutton.setOnLongClickListener(new View.OnLongClickListener() {

        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub

            //do your stuff here

            return true;
        }
    });
