StaggeredGridLayoutManager:添加边距使布局项被推到侧面 [英] StaggeredGridLayoutManager: Adding Margin makes the layout items pushed to the side

问题描述

所以，我正在做一个小项目，我想在文件中添加StaggeredGridLayoutManager.如果我不在布局中添加itemDecorator并且不添加margin或padding，则可以使用.一旦添加边距，它就会将列表推到一侧.我正在附上屏幕截图以澄清问题.

So, I'm working on a small project and I wanted to add StaggeredGridLayoutManagerto the file. While it works if I don't add an itemDecorator and no margin or padding in my layouts. As soon as I add margins it pushes the list to one side. I'm attaching a screenshot to clarify the issue.

这是我的代码:

recyclerView.setHasFixedSize(true);
    StaggeredGridLayoutManager gridLayoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
    recyclerView.addItemDecoration(new EqualSpaceItemDecoration(8));
    recyclerView.setLayoutManager(gridLayoutManager);
    recyclerView.setAdapter(adapter);

以及该项目的布局文件

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical">
  <android.support.v7.widget.CardView
    android:id="@+id/wallpaper_item_card"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:cardBackgroundColor="@color/cardview_light_background"
    app:cardCornerRadius="4dp"
    app:cardElevation="4dp"
    app:cardPreventCornerOverlap="false">

    <ImageView
      android:id="@+id/wallpaper_item_image"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>

  </android.support.v7.widget.CardView>
</LinearLayout>

我已经环顾了一段时间，但找不到解决该问题的方法.任何帮助表示赞赏.谢谢.

I've looked around for some time and am not able to find something that fixes the issues. Any help is appreciated. Thanks.

推荐答案

我不知道您是否已经找到解决方案，但我会留下评论，以防其他人看到问题.

I don't know if you've already found the solution, but I'll leave the comment in case anyone else sees the question.

我能够通过以下操作解决此问题:

I was able to solve this problem by doing the following:

layoutManager.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_NONE);

示例:

StaggeredGridLayoutManager layoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);          
layoutManager.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_NONE);
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(layoutManager);
