启动屏幕解锁Android应用程序

问题描述

我想建立一个锁屏更换申请。有什么办法来创建一个监听器/服务，将推出我的应用程序，只要用户唤醒/解锁屏幕？

I want to build a lock screen replacement application. Is there any way to create a listener/service that would launch my app whenever the user wakes up/unlocks the screen?

推荐答案

见的，您需要使用DeviceAdminReceiver对于disableing默认的Andr​​oid屏幕锁。

See source code of mylockforandroid and you will need use DeviceAdminReceiver for disableing default android screenlock.

用于启动活动时，用户解锁屏幕注册一个 Intent.ACTION_SCREEN_ON 和 Intent.ACTION_SCREEN_OFF 为：

for starting your activity when user unlock screen register an Intent.ACTION_SCREEN_ON and Intent.ACTION_SCREEN_OFF as:

在manifast.xml添加此code寄存器ScreenReceiver为：

add this code in manifast.xml register ScreenReceiver as:

<receiver android:name=".ScreenReceiver">
 <intent-filter>
 <action android:name="android.intent.action.SCREEN_OFF"/>
 <action android:name="android.intent.action.SCREEN_ON"/>
 </intent-filter>
 </receiver>

和添加ScreenReceiver.java为：

and add an ScreenReceiver.java as:

 public class ScreenReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
         if (intent.getAction().equals(Intent.ACTION_SCREEN_ON))
         {
            Intent intent = new Intent();
            intent.setClass(context, ScreenLockActivity.class);
            startActivity(intent);
         }
    }
}
