android之手机震动Vibrate

package cn.com.chenzheng_java; import android.app.Activity; import android.media.AudioManager; import android.os.Bundle; import android.os.Vibrator; import android.view.View; import android.widget.Toast; import android.widget.ToggleButton; public class VibrateActivity extends Activity { private ToggleButton button ; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.vibrate); button = (ToggleButton) findViewById(R.id.toggleButton1); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Boolean flag = button.isChecked(); if(flag){ // 获取Vibrate对象 Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE); // vibrator.vibrate(3000); // 设置Vibrate的震动周期 vibrator.vibrate(new long[]{1000,2000,3000,4000}, 0); Toast.makeText(VibrateActivity.this, "震动了", Toast.LENGTH_LONG).show(); } else{ } } }); } }

 

android.os.Vibrate代表着手机的振动器。用法很简单，通过getSystemService()方法获取示例，然后调用vibrate方法便可以实现震动。

要使用该振动器必须在AndroidManifest.xml中指定权限<uses-permission android:name="android.permission.VIBRATE"></uses-permission>
