（安卓）【學習記錄】安卓隱藏頂部狀態欄

public class GuiUtils {
    public static void hideStatusBar(AppCompatActivity activity1){
        WindowManager.LayoutParams lp2 = activity1.getWindow().getAttributes();
        //LayoutParams.FLAG_FULLSCREEN 強制屏幕狀態條欄彈出
        lp2.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
        activity1.getWindow().setAttributes(lp2);
        //不允許窗口擴展到屏幕之外
        activity1.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

        activity1.setContentView(R.layout.activity_main);
    }
}

構造靜態函數，傳入activity即可
