活动不会在全屏幕显示 [英] Activity doesn't show in full screen

问题描述

我定义我的项目新的活动，我有全屏一些麻烦。

I defined a new Activity on my project and I have some trouble with fullScreen.

我在清单文件中是这样定义的：

I defined in the manifest file like this:

<activity android:name=".Test"
     android:launchMode="singleInstance" android:screenOrientation="portrait"
     android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
     .............
>

如果我开始的活动从其他活动中，我得到了想要的全屏幕。问题是，当我开始这项活动从一个BroadcastReceiver - 我需要打开一个BroadcastReceiver这样的事情在这个活动：

If I start the activity from another activity, I got the desired full screen. The problem is when I start this activity from a BroadcastReceiver - I need to open this activity inside a BroadcastReceiver something like this:

public void onReceive(Context context, Intent intent) {
     Intent test = new Intent(context, Test.class);
     test.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
     context.startActivity(test);
}

我想这样过：

I tried like this too:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.test);
}

和无全屏如果该活动从我BroadcastReciever开始。

and no full screen if the activity starts from my BroadcastReciever.

为什么我没有得到充分的屏幕上这个案子？还有就是创建后的活动和可见的任何方式要求全屏？

Why I don't get full screen on this case? There is any way to request full screen after the Activity is created and visible?

推荐答案

我喜欢这个问题。有一种方法，我忽略了问题文本添加 - 我不认为这是相关的。因为我想这个活动来拦截（不反应），home键preSS，基于这个原因，我重写onAttachedToWindow（）方法是这样的：

I fond the issue. There is a method I omitted to add in question text - I didn't thought it's relevant. Because I want this activity to intercept (do not react) home button press, and for this reason I override onAttachedToWindow() method like this:

public void onAttachedToWindow() {
    getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
}

和这里是问题。有些时候，因为这个，我的活动并没有得到充分的画面。为了解决这个问题，我不知道这是不是最好的方式，我加了一个延迟到这一code，像这样的：

And here is the issue. Some times, because of this, my activity didn't get full screen. To fix this, I don't know if this is the best way, I added a delay to this code, like this:

public void onAttachedToWindow() {
    handler.sendEmptyMessageDelayed(100,100);
    super.onAttachedToWindow();
}

和处理程序：

public boolean handleMessage(Message msg) {
    getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
}

这解决了我的问题。我希望帮助别人！

and this solved my issue. I hope this help someone!
