Android的手机震动

实现手机震动

1.在AndroidManifest.xml中添加震动权限

<?xmlversion="1.0"encoding="utf-8"?>
<manifestxmlns:android="http://schemas.android.com/apk/res/android"
package="uni.vibrator"
android:versionCode="1"
android:versionName="1.0">
<uses-sdkandroid:minSdkVersion="8"/>

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

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

2.实现震动

packageuni.vibrator;

importandroid.app.Activity;
importandroid.content.Context;
importandroid.os.Bundle;
importandroid.os.Vibrator;

publicclassVibratorDemoActivityextendsActivity{
privateVibratorvibrator;
/**Calledwhentheactivityisfirstcreated.*/
@Override
publicvoidonCreate(BundlesavedInstanceState){
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

*/
}

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