Android實現(xiàn)調(diào)用震動的方法

這篇文章主要介紹了Android實現(xiàn)調(diào)用震動的方法,實例分析了Android中Vibrator類的調(diào)用與使用技巧,具有一定參考借鑒價值,需要的朋友可以參考下

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

調(diào)用Android系統(tǒng)的震動,只需要一個類 那就是Vibrator ,這個類在hard包中,一看系統(tǒng)級的服務(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,如果你的線程退出了,那么啟動的震動也會停止

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

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.

//傳遞一個整型數(shù)組作為關(guān)閉和開啟震動的持續(xù)時間,以毫秒為單位。第一個值表示等待震動開啟的毫秒數(shù),下一個值表示保持震動的毫秒數(shù),這個序列值交替表示震動關(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,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.

還包含一個方法叫做cancel,用來取消震動

看一段演示的代碼:

/*
 * @author octobershiner
 * SE.HIT
 * 一個使用android手機震動的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)置震動大小可以通過改變pattern來設(shè)定,如果開啟時間太短,震動效果可能感覺不到
     * */
    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 如果只想震動一次,index設(shè)為-1
  }
  public void onStop(){
    super.onStop();
    vibrator.cancel();
  }
}

希望本文所述對大家Android程序設(shè)計有所幫助。
