进入沉浸式全屏模式时，状态栏为白色 [英] Status Bar is white when entering immersive full screen mode

问题描述

我根据

我的问题是选择了取消沉浸式按钮，然后再次选择浸泡。尽管应用程序处于沉浸式模式，但状态栏处却是白色

这是我的隐藏和显示功能

  private void hideSystemUI（）{
 //设置IMMERSIVE标志。 
 //将内容设置为显示在系统栏下方，以便在隐藏和显示系统栏时不会调整内容
 //的大小。 
视图mDecorView = getWindow（）。getDecorView（）; 
 mDecorView.setSystemUiVisibility（
 View.SYSTEM_UI_FLAG_LAYOUT_STABLE 
 | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
 | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 
 | View.SYSTEM_UI_FLN_VIEWN b | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY）； 
} 
 
 private void showSystemUI（）{
 View mDecorView = getWindow（）。getDecorView（）; 
 mDecorView.setSystemUiVisibility（
 View.SYSTEM_UI_FLAG_LAYOUT_STABLE 
 | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
 | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN）; 
} 
  

和我的 activity_main.xml 是

 < FrameLayout xmlns：android = http://schemas.android.com/apk/res/android  
 android：layout_width = match_parent 
 android：layout_height = match_parent> 
 
< LinearLayout xmlns：android = http://schemas.android.com/apk/res/android 
 xmlns：app = http://schemas.android.com / apk / res-auto 
 xmlns：tools = http://schemas.android.com/tools 
 android：layout_width = match_parent 
 android：layout_height = match_parent 
 tools：context = com.example.aungmyolwin.immsersivedelete.MainActivity> 
 
<按钮
 android：id = @ + id / btn_immersive 
 android：layout_width = wrap_content 
 android：layout_height = wrap_content 
 android：text =使人身临其境 /> 
 
<按钮
 android：id = @ + id / btn_cancel_immersive 
 android：layout_width = wrap_content 
 android：layout_height = wrap_content 
 android：text = can沉浸式 /> 
 
<按钮
 android：id = @ + id / btn_show_dialog 
 android：layout_width = wrap_content 
 android：layout_height = wrap_content 
 android：text =显示对话框 /> 
 
< / LinearLayout> 
< / FrameLayout> 
  

解决方案

我暂时解决了这个问题。在进入全屏模式后执行 requestLayout

这是我的代码

  getWindow（）。addFlags（WindowManager.LayoutParams.FLAG_FULLSCREEN）; 
 getWindow（）。clearFlags（WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN）; 
 
 findViewById（android.R.id.content）.requestLayout（）; 
视图mDecorView = getWindow（）。getDecorView（）; 
 
 mDecorView.setSystemUiVisibility（
 View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
 | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 
 | View.SYSTEM_UI_FLAG_HIDE_UI_NAVIGATION 
 | ViewSYS。 SYSTEM_UI_FLAG_IMMERSIVE_STICKY）; 
  

I make a simple projet about immersive full screen mode according to Using Immersive Full-Screen Mode

But first of all it perfect fine when I select Make Immersive button, app is entering immersion fullscreen mode.

My problem is after selecting the Cancel Immersive button, and select Make Immsersive again. Although app is immersive mode, in the place of status bar is being white

Here is my hide and show functions

private void hideSystemUI() {
        // Set the IMMERSIVE flag.
        // Set the content to appear under the system bars so that the content
        // doesn't resize when the system bars hide and show.
        View mDecorView = getWindow().getDecorView();
        mDecorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
    }

    private void showSystemUI() {
        View mDecorView = getWindow().getDecorView();
        mDecorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                         |View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
    }

and my activity_main.xml is

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="com.example.aungmyolwin.immsersivedelete.MainActivity">

        <Button
            android:id="@+id/btn_immersive"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="make immersive" />

        <Button
            android:id="@+id/btn_cancel_immersive"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="cancle immersive" />

        <Button
            android:id="@+id/btn_show_dialog"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="show dialog" />

    </LinearLayout>
</FrameLayout>

解决方案

I solved this for temporary. Doing requestLayout after making fullscreen mode

Here is my codes

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

findViewById(android.R.id.content).requestLayout();
View mDecorView = getWindow().getDecorView();

                mDecorView.setSystemUiVisibility(
                        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                                | View.SYSTEM_UI_FLAG_FULLSCREEN
                                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
