Android 在线程结束前，禁止控件被点击

private boolean banClick;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
		
	new Thread(new Runnable() {
            @Override
            public void run() {
                banClick = true;
                getLocalImage2();// 耗时工作
                banClick = false;
            }
        }).start();
		
	tv_get_title.setOnClickListener(v -> {
            if (isFastClick() || banClick) return;
            showMediaFolderWindows(v);
        });
    }
