android实现手机震动

1.在AndroidManifest.xml中添加震动权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="uni.vibrator"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".VibratorDemoActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

</application>
<uses-permission android:name="android.permission.VIBRATE" />
</manifest>

2.实现震动

package uni.vibrator;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.os.Vibrator;

public class VibratorDemoActivity extends Activity {
private Vibrator vibrator;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

/*
* 想设置震动大小可以通过改变pattern来设定，如果开启时间太短，震动效果可能感觉不到
* */
vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
long [] pattern = {100,400,100,400}; // 停止 开启 停止 开启
vibrator.vibrate(pattern,2); //重复两次上面的pattern 如果只想震动一次，index设为-1

/*

如：只想震动一次，时间为200ms，可写为

long [] pattern = {0,200}; // 停止 开启
vibrator.vibrate(pattern,-1); //重复两次上面的pattern 如果只想震动一次，index设-1

*/
}

public void onStop(){
super.onStop();
vibrator.cancel(); //停止震动
}
}
