Android 实现点击震动效果

1 添加震动权限，在AndroidManifest.xml文件中添加:  <uses-permission android:name="android.permission.VIBRATE" />

2 代码

package com.test.ht;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.os.Vibrator;
import android.view.View;
import android.view.View.OnClickListener;

public class MainActivity extends ActionBarActivity implements OnClickListener {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    findViewById(R.id.button1).setOnClickListener(this);
    vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);  
  
  }

  Vibrator vibrator;

  @Override
  public void onClick(View v) {
    //震动30毫秒
    vibrator.vibrate(30);
  }

}
