Question

我有一个大约3000行的xml布局，作为问卷类型的应用程序的布局。问卷的每一页都在不同的线性布局中，我使用View.GONE或View.VISIBLE在代码中设置线性布局的可见性。这样，用户可以浏览页面，而无需每次都加载新的intents。

然而，当我快速浏览应用程序时（只需按下一步 button浏览屏幕），一些应该是View.GONE的元素显示并重叠 VISIBLE 项目。这只发生在其中包含列表视图的线性布局中。对于所有其他页面。

我可以快速浏览它们，但只有View.GONE元素中包含列表视图的那些元素有时会在我导航太快时显示出来。我怎样才能解决这个问题？如果您想要代码，请告诉我...但是xml非常大。

这是我的xml代码示例，我在xml中有3000行重复...

然后这是我在代码中显示和隐藏线性布局的示例，重复24个左按钮和24个右按钮：

        {

            package_normal_area_details.setVisibility(View.GONE);

            package_normal_collecter_details.setVisibility(View.GONE);
            package_normal_additional_information.setVisibility(View.GONE);

             package_normal_owner_details.setVisibility(View.VISIBLE);
             package_normal_owner_details.bringToFront();
        }
    });

    right24.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View v)
        {
            if(Session.signatureIsCaptured)
            {
            package_normal_welcomescreen.setVisibility(View.GONE);

            package_normal_additional_information.bringToFront();
            }
            else
            {
                Toast.makeText(Screen_Package_Normal.this, "Authorized Signature Required", Toast.LENGTH_LONG).show();
            }

        }

    });

我有不同类型的listviews和适配器，内置自定义和android。我认为问题不在于适配器，因为它可以很好地显示列表视图，甚至在列表视图填充之前就会出现问题...

Answer 1

我有一个临时修复，不知道这是多么正确这是一个答案，但这解决了我的问题......我将其应用于我的整个布局，并在我隐藏和显示布局时添加动画，从而减慢它们向下一点，删除重叠的元素。

这是我添加到我的布局中的内容：

android：animateLayoutChanges =“true”

设置可见性时，XML listview会重叠元素
