【问题描述】:
片段集recyclerView列数:
sortRecyclerView.setHasFixedSize(true);
RecyclerView.LayoutManager rvLayoutManager = new GridLayoutManager(getActivity(), 2);
sortRecyclerView.setLayoutManager(rvLayoutManager);
这里布局那个内容recyclerView:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/sortRecyclerView"
android:layout_width="0dp"
android:layout_height="0dp"
android:scrollbars="vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
recyclerView中这里的item布局:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:background="@color/place_holder_color">
<ImageView
android:id="@+id/imageViewPhoto"
android:layout_width="@dimen/preview_image_height"
android:layout_height="@dimen/preview_image_height"
android:scaleType="centerCrop"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
结果如下:
我需要下一个:
- 左右两侧设置20dp
- 在 2 列之间设置 10 dp
