Question

我在一个表（行）布局中有一个recylcerView，在NestedScrollView中，所有这些都将layout_width属性设置为match_parent。我遇到的问题是recyclelerView的滚动没有工作，但是当试图完成滚动（使用NestedScrollView）时，我发现这不是真正的问题。问题是我的水平recylcerView的宽度，扩展了设备的宽度。我只知道它，因为我的recyclerView上方的行没有显示正确的文本。

下图显示了RV和上面的textRow的行为 screenshot

左边的图像：在这里你可以看到上面文本行中的文字丢失了＆＃34; h word＆＃34;
标有2的图像：这是预期的输出。

我只实现了所期望的＆＃34;正确的＆＃34; size，如果我将recyclerview的layout_width设置为＆＃34; 200dp＆＃34;。但我不想要一个固定的尺寸（由于不同的设备）。

我尝试使用以下代码动态设置RV的layout_width但未成功：

LinearLayoutManager llm = new LinearLayoutManager(this.getContext(), LinearLayoutManager.HORIZONTAL, false);
    mRecyclerViewAttachments.setLayoutManager(llm);
    ViewGroup.LayoutParams params = mRecyclerViewAttachments.getLayoutParams();
    int newWidth = (int) (params.width * 0.9);
    mRecyclerViewAttachments.setLayoutParams(params);

任何人都可以帮我解决这个问题吗？下面是对话框的完整布局xml（RV最后出现）：

Answer 1

你的树应该是这样的

<NestedScrollView>

  <LinearLayout  orientation = vertical>

     <EditText>

     <TextView>

     <Recyclerview>

  </LinearLayout>

</NestedScrollView>

RecyclerView的宽度超过DeviceWidth并销毁TableLayout
