Android 切换ListViews可见性会导致滚动问题
我尝试在一个地方设置两个ListView，一次只能看到其中一个。（这是使用setVisibility（View.GONE）以编程方式设置的） 在第二个ListView可见并消失后，第一个ListView不会滚动。我做了一些测试，发现第二个ListView的onScrollListener总是捕获事件。 你知道我如何设置它吗？可见ListView的onScrollListener总是捕获事件？ 我已经尝试了requestFocus（），但它不起作用 下面是代码中的一些代码：Android 切换ListViews可见性会导致滚动问题,android,listview,scroll,visibility,Android,Listview,Scroll,Visibility,我尝试在一个地方设置两个ListView，一次只能看到其中一个。（这是使用setVisibility（View.GONE）以编程方式设置的） 在第二个ListView可见并消失后，第一个ListView不会滚动。我做了一些测试，发现第二个ListView的onScrollListener总是捕获事件。 你知道我如何设置它吗？可见ListView的onScrollListener总是捕获事件？ 我已经尝试了requestFocus（），但它不起作用 下面是代码中的一些代码： public void

我设法解决了这个问题。我不知道为什么在能见度改变的情况下会有奇怪的行为，所以毕竟我做了一个变通。 在代码中，以前存在可见性改变，现在我从父级中删除不应该出现在屏幕上的布局，并添加应该可见的布局。现在，两个列表视图都可以完美地工作。我认为它比可见性设置慢一点，但它可以工作。 必须始终在屏幕上显示两个标题（移动服务标题和家庭服务标题），这就是以编程方式设置布局参数的原因 切换功能：
public void toggle_services(View v){
LinearLayout.LayoutParams bigWieght=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, 11f);
LinearLayout.LayoutParams smallWieght=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, 1f);
if(isHomeVisible){
AnimationHelper.slide_up(this, home_services_detail);
homeServicesLinearLayout.removeView(home_services_detail);
homeServicesLinearLayout.setLayoutParams(bigWieght);
mobileServicesLinearLayout.addView(mobile_services_detail);
AnimationHelper.slide_down(this, mobile_services_detail);
mobileServicesLinearLayout.setLayoutParams(smallWieght);
} else {
AnimationHelper.slide_up(this, mobile_services_detail);
mobileServicesLinearLayout.removeView(mobile_services_detail);
mobileServicesLinearLayout.setLayoutParams(bigWieght);
homeServicesLinearLayout.addView(home_services_detail);
AnimationHelper.slide_down(this, home_services_detail);
homeServicesLinearLayout.setLayoutParams(smallWieght);
}
isHomeVisible=!isHomeVisible;
