android--手机震动--Vibrator

android.os.Vibrator代表这手机的振动器，是通过this.getSystemService(Service.VIBRATOR_SERVICE)获取的，然后通过用vibrate来实现震动，用cancel方法来取消震动。

1、获取震动器的实例

Vibrator vibrator = (Vibrator) this.getSystemService(Service.VIBRATOR_SERVICE);

2、设置震动时长，单位是ms

vibrator.vibrate(2500);

3、也可以设置有节奏的

vibrator.vibrate(new long[]{10, 10, 50, 50, 50}, -1);

注意：-1代表着震动不重复

4、使用振动器必须要在AndroidManifest.xml中指定权限

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

 

实例如下：

1、布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        >

        <ToggleButton
            android:id="@+id/tb1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="false"
            android:textOff="@string/vibrate"
            android:textOn="@string/cancel" />

        <TextView
            android:id="@+id/tv1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/vibrateoff"
            />
     </LinearLayout>
     <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        >

        <ToggleButton
            android:id="@+id/tb2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="false"
            android:textOff="@string/vibrate"
            android:textOn="@string/cancel" />

        <TextView
            android:id="@+id/tv2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/vibrateoff"
            />
     </LinearLayout>
</LinearLayout>

2、代码：

package com.phoneVibrate;

import android.app.Activity;
import android.app.Service;
import android.os.Bundle;
import android.os.Vibrator;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.TextView;
import android.widget.ToggleButton;

public class PhoneVibrateActivity extends Activity {
    Vibrator vibrator;
    TextView tv1;
    TextView tv2;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tv1 = (TextView) findViewById(R.id.tv1);
        tv2 = (TextView) findViewById(R.id.tv2);
        vibrator = (Vibrator) this.getSystemService(Service.VIBRATOR_SERVICE);
        ToggleButton tb1 = (ToggleButton) findViewById(R.id.tb1);
        tb1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
   @Override
   public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(isChecked){
     vibrator.vibrate(new long[]{10, 10, 50, 50, 50}, -1);
     tv1.setText(R.string.vibrateon);
    }else{
     vibrator.cancel();
     tv1.setText(R.string.vibrateoff);
    }
   }
  });
        ToggleButton tb2 = (ToggleButton) findViewById(R.id.tb2);
        tb2.setOnCheckedChangeListener(new OnCheckedChangeListener() {
   
   @Override
   public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(isChecked){
     vibrator.vibrate(2500);
     
     tv2.setText(R.string.vibrateon);
    }else{
     vibrator.cancel();
     tv2.setText(R.string.vibrateoff);
    }
   }
  });
    }
}

3、AndroidManifest.xml

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

    <uses-sdk android:minSdkVersion="15" />
 <uses-permission android:name="android.permission.VIBRATE"/>
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".PhoneVibrateActivity"
            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>

</manifest>
