App Image

有什么问题?

:在上图中,您可以看到浮动图标或视图未正确对齐的第3项,如您在其他项目中看到的那样。

:每次打开此屏幕时,某些项目的锚点视图都无法正确对齐。

我做了什么?

我使用GridLayout管理器实现了Recycler。

//setting Grid layout
        GridLayoutManager gridLayoutManager = new GridLayoutManager(context, ROW_COUNT, LinearLayoutManager.VERTICAL, false);
        mRecyclerView.setLayoutManager(gridLayoutManager);

和自定义适配器。

项目布局:

尝试将代码修改为:

<de.hdodenhof.circleimageview.CircleImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:layout_marginLeft="16dp"
    android:src="@drawable/user_profile_image_dummy"
    app:civ_border_color="@color/white"
    app:civ_border_width="2dp"
    app:layout_anchor="@id/service_description"
    app:layout_anchorGravity="bottom|start"

    />

包含app:layout_anchorGravity="bottom|start"
