Android全屏显示刘海屏适配

状态栏全屏适配

通过代码实现全屏：

import android.os.Build;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;

import androidx.fragment.app.FragmentActivity;

public class FullScreenUtil {
    /**
     * 全屏布局，不显示状态栏，适配刘海屏
     */
    public static void fullScreen(FragmentActivity activity) {
        Window window = activity.getWindow();
        window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
        //允许window 的内容可以上移到刘海屏状态栏
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            WindowManager.LayoutParams lp = window.getAttributes();
            lp.layoutInDisplayCutoutMode =
                    WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
            window.setAttributes(lp);
        }
    }
}

通过设置主题theme实现全屏
