Button的五种点击事件

1.内部类方式

class MyOnClickListener implements View.OnClickListener{


    /**
     * Called when a view has been clicked.
     *
     * @param v The view that was clicked.
     */
    @Override
    public void onClick(View v) {

    }
}

        MyOnClickListener l = new MyOnClickListener();
        bt.setOnClickListener(l);

 

 

2.匿名内部类方式

Button bt = (Button) findViewById(R.id.button);

//设置监听器,采用匿名内部类方式
bt.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //获取输入电话号码字符串
        String number = et.getText().toString().trim();
        Log.e("dail","click");
        Log.e("dail",number);
        //打电话
        dailPhone(number);
    }
});

3.外部类方式

package market.phone;

import android.view.View;

/**
 * Created by Administrator on 2017/6/13.
 */

public class POnClickListener implements View.OnClickListener {
    /**
     * Called when a view has been clicked.
     *
     * @param v The view that was clicked.
     */
    @Override
    public void onClick(View v) {
        
    }
}

 bt.setOnClickListener(new POnClickListener());

 

4.xml方式

    //xml配置的按钮点击后要执行的方法
    public void click(View v){

    }

5.本类实现监听接口，实现多个按钮的点击响应
