安卓app实现全面屏显示

主要修改类文件MainActivity.java

重写类方法onCreate

适配全面屏显示，消除letterbox黑边

  • 在onCreate方法下编写以下内容，设置app显示布局模式layoutInDisplayCutoutMode,官方详细描述:https://developer.android.com/develop/ui/views/layout/display-cutout?hl=zh-cn#handle

        super.onCreate(savedInstanceState);
  
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
  
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            getWindow().getAttributes().layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS;
        }

    @RequiresApi(api = Build.VERSION_CODES.R)
private void hideSystemUI() {
        // 获取当前窗口的装饰视图
        View decorView = getWindow().getDecorView();
  
        // 获取 WindowInsetsController
        WindowInsetsController insetsController = decorView.getWindowInsetsController();
        if (insetsController != null) {
            // 设置系统 UI 行为: 可以通过滑动调出系统UI，短暂显示系统UI
            insetsController.setSystemBarsBehavior(WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);
  
            // 隐藏手势条
            insetsController.hide((WindowInsets.Type.systemGestures()));
  
            // 隐藏系统栏：状态栏、导航栏
            insetsController.hide((WindowInsets.Type.systemBars()));
              
        }
