Question

我正在尝试构建一个基本的警报应用程序，在用户输入时振动。我刚开始使用Android，所以它只是一个基本的应用程序。

我使用的概念是使用当前millisecs的差异和输入时间的毫秒作为notification.vibrate方法的延迟。但是，振动不会发生在进入时间。

它甚至没有发生在我试过的其他延迟上。我不知道问题是什么。我做了一个简单的通知振动程序一段时间后，它运行得很好。任何帮助表示赞赏。但是这个应用程序只是在单击Button。

时关闭

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
public void onClick(View v)
{
 alarm();
}

protected void alarm()
{
 EditText min = (EditText)findViewById(R.id.et1);
 EditText hour = (EditText)findViewById(R.id.et3);
 EditText sec = (EditText)findViewById(R.id.et2);
 long delay =  Integer.valueOf(min.toString())*60       +Integer.valueOf(sec.toString())+Integer.valueOf(hour.toString())*3600;
 NotificationManager nm =  (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
Intent i = new Intent(this, alarm2.class); //New intent to launch the other activity that would be launched when the user clicks on the notification!
 i.putExtra("id", 2);
 PendingIntent p = PendingIntent.getActivity(this, 0, i, 0);//pendingintent p will be launched when the user clicks on notification which is in turn connected to intent i! 
 Notification notif = new Notification(R.drawable.notif, "Alarm !",  System.currentTimeMillis());
    notif.setLatestEventInfo(this, "User ALARM !", "Get up Lazy  !", p);
 notif.vibrate= new long[]{delay*1000 ,500,250,500};
 nm.notify(2, notif);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
     getMenuInflater().inflate(R.menu.main, menu);
     return true;
}

}

Alarm2是第二个完成终止通知任务的类。

这是Manifest文件！

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

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.VIBRATE"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.alarm.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
     <activity
        android:name=".alarm2"
        android:label="alarm 2" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
   </application>

 </manifest>

您可以尝试使用通知构建器

private static NotificationCompat.Builder buildNotificationCommon(Context _context, .....) {
            NotificationCompat.Builder builder = new NotificationCompat.Builder(_context)
            .setWhen(System.currentTimeMillis()).......;
     //Vibration
        builder.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 });

     //LED
        builder.setLights(Color.RED, 3000, 3000);

     //Ton
        builder.setSound(Uri.parse("uri://sadfasdfasdf.mp3"));

    return builder;
   }

您也可以尝试使用vibrator

 import android.os.Vibrator;
 ...
 Vibrator v = (Vibrator) this.context.getSystemService(Context.VIBRATOR_SERVICE);
 // Vibrate for 500 milliseconds
 v.vibrate(500);

如果这些都不起作用，那么您的手机可能没有启用振动或者某种程度上已经损坏
