android 手机震动Vibrator类用法demo



package com.example.ch10_vibratortest;

import android.app.Activity;
import android.app.Service;
import android.os.Bundle;
import android.os.Vibrator;
import android.view.MotionEvent;
import android.widget.Toast;

public class MainActivity extends Activity {

   private Vibrator vibrator;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // 获取系统的Vibrator服务
        vibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE);
    }

    // 重写onTouchEvent方法，当用户触碰触摸屏时触发该方法
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        Toast.makeText(this, "手机振动", 5000).show();
        // 控制手机震动2秒
        vibrator.vibrate(2000);
        return super.onTouchEvent(event);
    }

}

android工程AndroidManifest.xml文件需要增加

 <!-- 授予程序访问振动器的权限 -->
 <uses-permission android:name="android.permission.VIBRATE"/>
