【问题讨论】：

将列表视图高度设置为 wrap_content。希望这会对你有所帮助。
不，保持不变:-(
您是否在代码中显示了列表视图，您是否还在向其附加适配器？
你需要在ListView周围创建一个不延伸到Activity全尺寸的容器
将RelativeLayout设为父布局，并仅在SwipeToRefreshLayout中包含ListView。

标签： android swiperefreshlayout

【解决方案1】：

你可以使用滚动视图

<ScrollView
  android:layout_width="match_parent"
  android:layout_height="match_parent">
    // layout content
</ScrollView>

更多详情请参考link

希望这会有所帮助。

【讨论】：

ScrollView 应该永远与 ListView 一起使用。这是在 Android 文档中。
@criket_007 你能帮我找到答案吗？
是的，不是使用 listView，但您可以在 listView 布局下方放置一个滚动视图并尝试，但您可能需要更改 listView 的高度。

【解决方案2】：

替换这个

<ListView
    android:id="@+id/post"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@null"   
    android:visibility="gone" />

与

<ListView
    android:id="@+id/post"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@null"
    android:layout_above="@+id/udyopro_post"      
    android:visibility="gone" />

也替换掉这个

<RelativeLayout
    android:layout_below="@+id/post"
    android:id="@+id/udyopro_post"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="gone">

有了这个

<RelativeLayout
    android:layout_alignParentBottom="true"
    android:id="@+id/udyopro_post"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="gone">

清理你的项目然后运行你的项目，如果你得到错误然后发布完整的错误
