所以，我想开发一个自定义锁屏

So I am trying to develop a custom lockscreen

但我的广播接收器，将不会触发

but my broadcastreceiver won't fire

我的清单：

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="schemas.android/apk/res/android" package="org.alexander.fuchs.lockscreen" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" /> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".app" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name=".myreceiver"> <intent-filter> <action android:name="android.intent.action.SCREEN_OFF"/> <action android:name="android.intent.action.SCREEN_ON"/> <action android:name="android.intent.action.BOOT_COMPLETED"/> </intent-filter> </receiver> </application> </manifest>

我的接收器：

public class myreceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Log.d("receiver","works"); Toast.makeText(context,"works",Toast.LENGTH_LONG).show(); Intent in=new Intent(context,app.class); context.startActivity(in); } }

接收者应该告诉我，它被激发：D但是疗法不在logcat的任何日志

the receiver should show me that it is fired :D but ther aren't any logs in logcat

推荐答案

很好，在屏幕关闭，在屏幕上，这不可能是清单里，但只在运行时。看到这一点：thinkandroid.word$p$pss/2010/01/24/handling-screen-off-and-screen-on-intents/

well , for the screen off and screen on , this cannot be inside the manifest , but only at runtime . see this: thinkandroid.wordpress/2010/01/24/handling-screen-off-and-screen-on-intents/

在启动时，它必须在清单中，所以别的东西是错的it.check类的路径。这肯定是问题的原因。

for the bootup , it must be in the manifest , so something else is wrong with it.check the path of the class. this is surely the cause of the problem.
