本文實(shí)例講述了Android實(shí)現(xiàn)調(diào)用震動(dòng)的方法。分享給大家供大家參考，具體如下：

調(diào)用Android系統(tǒng)的震動(dòng)，只需要一個(gè)類 那就是Vibrator ,這個(gè)類在hard包中，一看系統(tǒng)級(jí)的服務(wù)，又要通過manifest.xml文件設(shè)置權(quán)限了

<?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>

下面還是一起學(xué)習(xí)一下SDK吧

Class that operates the vibrator on the device.
If your process exits, any vibration you started with will stop.

//Vibrator類用來操作設(shè)備上的震動(dòng)，如果你的線程退出了，那么啟動(dòng)的震動(dòng)也會(huì)停止

public void vibrate (long[] pattern, int repeat)
Since: API Level 1

Vibrate with a given pattern.  //根據(jù)給定的節(jié)奏震動(dòng)

Pass in an array of ints that are the durations for which to turn on or off the vibrator in milliseconds. The first value indicates the number of milliseconds to wait before turning the vibrator on. The next value indicates the number of milliseconds for which to keep the vibrator on before turning it off. Subsequent values alternate between durations in milliseconds to turn the vibrator off or to turn the vibrator on.

//傳遞一個(gè)整型數(shù)組作為關(guān)閉和開啟震動(dòng)的持續(xù)時(shí)間，以毫秒為單位。第一個(gè)值表示等待震動(dòng)開啟的毫秒數(shù)，下一個(gè)值表示保持震動(dòng)的毫秒數(shù)，這個(gè)序列值交替表示震動(dòng)關(guān)閉和開啟的毫秒數(shù)

To cause the pattern to repeat, pass the index into the pattern array at which to start the repeat, or -1 to disable repeating.
//為了重復(fù)的按設(shè)定的節(jié)奏震動(dòng)，傳遞index參數(shù)表示重復(fù)次數(shù)，用-1表示不重復(fù)。

Parameters
pattern     an array of longs of times for which to turn the vibrator on or off.
repeat     the index into pattern at which to repeat, or -1 if you don't want to repeat.

還包含一個(gè)方法叫做cancel，用來取消震動(dòng)

看一段演示的代碼：

/*
 * @author octobershiner
 * SE.HIT
 * 一個(gè)使用android手機(jī)震動(dòng)的demo
 * */
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);
    /*
     * 想設(shè)置震動(dòng)大小可以通過改變pattern來設(shè)定，如果開啟時(shí)間太短，震動(dòng)效果可能感覺不到
     * */
    vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
    long [] pattern = {100,400,100,400}; // 停止 開啟 停止 開啟
    vibrator.vibrate(pattern,2); //重復(fù)兩次上面的pattern 如果只想震動(dòng)一次，index設(shè)為-1
  }
  public void onStop(){
    super.onStop();
    vibrator.cancel();
  }
}

希望本文所述對(duì)大家Android程序設(shè)計(jì)有所幫助。
