Question

我知道这个问题已经回答了很多次，但是某些设备上的全屏显示存在问题。

示例：

（很明显，导航栏是自动隐藏的。）

存在此问题的设备的纵横比为21：9（Motorola One Vision Android 9）。

带VLC的全屏显示

对于所有仿真器（并在S9 +，J5-6-7，Android TV中进行测试...），它都能完美运行：

在大多数设备（无论是电视，平板电脑还是任何设备）中，全屏模式都能完美体现。

我正在使用Android的VLC库。

XML代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/player_root"
    android:layout_width="fill_parent"

    android:keepScreenOn="true"

    <!--
     the double FrameLayout is necessary here to do cropping on the bottom right
     (which requires the surface not be centered), while keeping the result centered
    -->

AndroidManifest：

            android:theme="@style/PlayerVLC"

            tools:ignore="InnerclassSeparator" />

样式主题：

<style name="PlayerVLC" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->

        <item name="android:statusBarColor" tools:targetApi="lollipop">@color/transparent</item>
        <item name="android:navigationBarColor" tools:targetApi="lollipop">@color/transparent</item>

    </style>

用于全屏显示的代码：

private void hideSystemUI() {
        // Enables regular immersive mode.
        // For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE.
        // Or for "sticky immersive," replace it with SYSTEM_UI_FLAG_IMMERSIVE_STICKY
        View decorView = getWindow().getDecorView();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            decorView.setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_IMMERSIVE
                            // Set the content to appear under the system bars so that the
                            // content doesn't resize when the system bars hide and show.
                            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            // Hide the nav bar and status bar
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN);
        }
        v.setVisibility(View.INVISIBLE);
    }

    // Shows the system bars by removing all the flags
    // except for the ones that make the content appear under the system bars.
    private void showSystemUI() {

        View decorView = getWindow().getDecorView();
        decorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

        v.setVisibility(View.VISIBLE);


    }

我也使用了这些标志，但是在setContentView (R.layout.playervlc);之前/之后仍然无法使用。

        Window w = getWindow();
        w.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

如何使用视频进行全屏活动？
