MainActivity

 

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.example.administrator.myapplication.MainActivity"    android:weightSum="1">    <Button        android:id="@+id/btn_hasVibrator"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="監測手機是否有震動器" />    <Button        android:id="@+id/btn_short"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="短震動" />    <Button        android:id="@+id/btn_long"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="長震動" />    <Button        android:id="@+id/btn_rhythm"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="節奏震動" />    <Button        android:id="@+id/btn_cancle"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="取消震動" /></LinearLayout>

一、獲得系統的Vibrator

 

 

        myVibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE);        mContext = MainActivity.this;

 

二、判斷並設定頻率不同的震動器

 

abstract void cancel()：關閉或者停止震動器

abstract boolean hasVibrator()：判斷硬體是否有震動器

void vibrate(long milliseconds)：控制手機震動為milliseconds毫秒

void vibrate(long[] pattern,int repeat):指定手機以pattern指定的模式震動

第一個參數：new int[200,400,600,800],在200,400,600,800這個時間交替啟動與關閉震動器
第二個參數：重複次數,如果是-1的只震動一次,如果是0的話則一直震動

 

 public void onClick(View v) {        switch (v.getId()) {            case R.id.btn_hasVibrator:                Toast.makeText(mContext, myVibrator.hasVibrator() ? "當前裝置有震動器" : "當前裝置無震動器",                        Toast.LENGTH_SHORT).show();                break;            case R.id.btn_short:                myVibrator.cancel();                myVibrator.vibrate(new long[]{100, 200, 100, 200}, 0);                Toast.makeText(mContext, "短震動", Toast.LENGTH_SHORT).show();                break;            case R.id.btn_long:                myVibrator.cancel();                myVibrator.vibrate(new long[]{100, 100, 100, 1000}, 0);                Toast.makeText(mContext, "長震動", Toast.LENGTH_SHORT).show();                break;            case R.id.btn_rhythm:                myVibrator.cancel();                myVibrator.vibrate(new long[]{500, 100, 500, 100, 500, 100}, 0);                Toast.makeText(mContext, "節奏震動", Toast.LENGTH_SHORT).show();                break;            case R.id.btn_cancle:                myVibrator.cancel();                Toast.makeText(mContext, "取消震動", Toast.LENGTH_SHORT).show();        }    }

 

三、開啟系統許可權

 

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