“锁定屏幕”，带有自定义安全密码

I have looked through lots of similar questions, and I have found out that it is not possible to make a Lock Screen as the standard android lockers. The thing that is possible is to make an app that disables the LockScreen and uses a different "lock" instead of the standard one. I am thinking about making a custom lockscreen with a different type of lock. What I do not know is possible is:

我已经查看了很多类似的问题,我发现不可能将锁屏作为标准的android锁柜。可能的做法是创建一个禁用LockScreen的应用程序,并使用不同的“锁定”而不是标准的“锁定”。我正在考虑使用不同类型的锁来制作自定义锁屏。我不知道的可能是:

Are there any ways of useing a .xml layout for a lockscreen

是否有任何方法可以为锁屏使用.xml布局

Can I then write it like a normal app

我可以像普通的应用程序一样编写它

I do not want referances to existing apps on the market.

我不想要对市场上现有的应用程序进行反馈。

I believe you are right because i did not find a way to replace the original lockscreen either. As you said, we can disable the original and fake another one.

我相信你是对的,因为我也找不到替换原来的锁屏的方法。如你所说,我们可以禁用原件并伪造另一个。

I have a concept and you can find this page helpful too: http://chandan-tech.blogspot.com/2010/10/handling-screen-lock-unlock-in-android.html

我有一个概念,你也可以找到这个页面:http://chandan-tech.blogspot.com/2010/10/handling-screen-lock-unlock-in-android.html

You disable the original, add a listener to ACTION_SCREEN_ON, and once it is triggered, display your fake lockscreen, and from now you can write it like a normal app and i believe xml layout is totally practical.

您禁用了原始内容,为ACTION_SCREEN_ON添加了一个侦听器,一旦触发它,就会显示您的假锁屏,从现在开始您可以像普通应用程序一样编写它,我相信xml布局是完全实用的。

To actually implement it , a service should also be made and has to run with system startup. In your activity you should also disable notification bar and buttons .

要实际实现它,还应该创建一个服务,并且必须在系统启动时运行。在您的活动中,您还应该禁用通知栏和按钮。

You can try overriding KeyguardManager

您可以尝试重写KeyguardManager

KeyguardManager.KeyguardLock key;
KeyguardManager km=(KeyguardManager)getSystemService(KEYGUARD_SERVICE);
//depreciated
key=km.newKeyguardLock("IN");

You must insert this in a service.Go as something like:

您必须将其插入服务中。如下所示:

public class LockService extends Service{
BroadcastReceiver receiver;
@override
@SuppressWarnings("deprecation")
public void onCreate(){
KeyguardManager.KeyguardLock key;
KeyguardManager km=(KeyguardManager)getSystemService(KEYGUARD_SERVICE);
//depreciated
key=km.newKeyguardLock("IN");
IntentFilter filter=new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
filter.addAction(Intent.ACTION_BOOT_COMPLETED);
receiver=new LockscreenReceiver();
registerReceiver(receiver,filter);
super.onCreate();
}

And then on LockscreenReceiver, you must implement this action:

然后在LockscreenReceiver上,您必须实现此操作:

public class LockscreenReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context,Intent intent){
String action=intent.getAction();
//if the screen was recently enabled, do this:
//If the screen was just turned on or it just booted up, start your Lock Activity
        if(action.equals(Intent.ACTION_SCREEN_OFF) || action.equals(Intent.ACTION_BOOT_COMPLETED))
        {
            Intent i = new Intent(context, MainActivity.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
}
}

afterwards, you must register or call service in MainActivity

之后,您必须在MainActivity中注册或致电服务

startService(new Intent(this,LockscreenService.class));
