Question

将immersive mode与viewPager视图一起使用时 - ＆gt; fullscreen_content 未调整为全屏。

但是在Android工作室提供的模板中使用相同的代码它可以正常工作。

我最好的猜测是它与android:fitsSystemWindows="true"有关。

如果您看到下面的屏幕截图，则绿色是使用android:fitsSystemWindows="true"的视图的背景，并且浅色用作整个活动的背景以进行调试。

解决方案是什么？还有其他方法吗？

实施沉浸式的XML活动

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context=".Camera.CameraActivity">

    <FrameLayout
        android:fitsSystemWindows="true"
        android:background="@color/colorAccent"
        android:id="@+id/fullscreen_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".Camera.CameraActivity">

        <com.brotherpowers.audiojournal.View.AJViewPager
            android:id="@+id/container"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

        <com.viewpagerindicator.CirclePageIndicator
            android:id="@+id/viewpager_indicator"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:padding="@dimen/spacing.8"
            app:fillColor="@color/viewpager_active"
            app:pageColor="@color/viewpager_inactive"
            app:strokeColor="@android:color/transparent"/>

    </RelativeLayout>

</FrameLayout>

JAVA活动显示/隐藏全屏

private final Handler uiHandler = new Handler();
    private boolean fullScreen;

    private void hide() {
        // Hide UI first
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.hide();
        }
        fullScreen = true;

        // Schedule a runnable to remove the status and navigation bar after a delay
        uiHandler.removeCallbacks(showRunnable);
        uiHandler.postDelayed(hideRunnable, 100);
    }


    private void show() {
        // Show the system bar
        _contentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
        fullScreen = false;

        // Schedule a runnable to display UI elements after a delay
        uiHandler.removeCallbacks(hideRunnable);
        uiHandler.postDelayed(showRunnable, 100);
    }

    private final Runnable showRunnable = () -> {
        // Delayed display of UI elements
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.show();
        }
        _contentView.requestLayout();
    };

    private final Runnable hideRunnable = () -> {
        // removal of status and navigation bar
        _contentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
                | View.SYSTEM_UI_FLAG_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

        _contentView.requestLayout();
    };

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);

        final int flags = 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;

        SystemUiHelper uiHelper =  new SystemUiHelper(this, SystemUiHelper.LEVEL_IMMERSIVE ,flags);
        uiHelper.hide();



}
