Android 9.0系统中提供了3种layoutInDisplayCutoutMode属性来允许应用自主决定该如何对刘海屏设备进行适配。

LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT：这是一种默认的属性，在不进行明确指定的情况下，系统会自动使用这种属性。这种属性允许应用程序的内容在竖屏模式下自动延伸到刘海区域，而在横屏模式下则不会延伸到刘海区域。

LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES：这种属性表示，不管手机处于横屏还是竖屏模式，都会允许应用程序的内容延伸到刘海区域。

LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER：这种属性表示，永远不允许应用程序的内容延伸到刘海区域。

1、先创建一个values-v28文件夹，并在其中创建一个styles.xml文件，然后在指定Activity的主题下加入如下配置即可：

<style name="ActivityTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowLayoutInDisplayCutoutMode">
        shortEdges <!-- 可选项 default, shortEdges, never -->
    </item>
</style>

2、Activity代码如下：

public class FullScreenActivity extends AppCompatActivity {
    private TextView text;
    private LinearLayout rootLayout;

    @Override
    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.activity_full_screen);
        text = findViewById(R.id.text);
        rootLayout = findViewById(R.id.root);

        View decorView = getWindow().getDecorView();
        int option = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(option);
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.hide();
        }
        if (Build.VERSION.SDK_INT >= 28) {
            WindowManager.LayoutParams params = getWindow().getAttributes();
            params.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
            getWindow().setAttributes(params);
        }

        //设置控件的安全区域
        if (Build.VERSION.SDK_INT >= 28) {
            rootLayout.setOnApplyWindowInsetsListener(new View.OnApplyWindowInsetsListener() {
                @Override
                public WindowInsets onApplyWindowInsets(View view, WindowInsets windowInsets) {
                    DisplayCutout displayCutout = windowInsets.getDisplayCutout();
                    if (displayCutout != null) {
                        int left = displayCutout.getSafeInsetLeft();
                        int top = displayCutout.getSafeInsetTop();
                        int right = displayCutout.getSafeInsetRight();
                        int bottom = displayCutout.getSafeInsetBottom();

                        LinearLayout.LayoutParams topParams = (LinearLayout.LayoutParams) text.getLayoutParams();
                        topParams.setMargins(left, top, right, bottom);
                        text.setLayoutParams(topParams);
                    }
                    return windowInsets.consumeSystemWindowInsets();
                }
            });
        }
    }

    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        if (hasFocus && Build.VERSION.SDK_INT >= 19) {
            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
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        }
    }
}

3、布局文件如下：

<?xml version="1.0" encoding="utf-8"?>
<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.jinlanmeng.demo.ui.FullScreenActivity"
    android:background="@color/colorAccent"
    android:orientation="vertical"
    android:id="@+id/root">
    <TextView
        android:id="@+id/text"
        android:textSize="50sp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="全屏喔"
        android:background="@color/cardview_dark_background"/>

</LinearLayout>
