Fragment set recyclerView columns number:

sortRecyclerView.setHasFixedSize(true);
        RecyclerView.LayoutManager rvLayoutManager = new GridLayoutManager(getActivity(), 2);
        sortRecyclerView.setLayoutManager(rvLayoutManager);

这里布局内容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>

此处在recyclerView中的项目布局:

<?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:

rv

我需要接下来:

  1. 在左侧和右侧设置20dp
  2. 在2列之间设置10 dp

你可以设置这样的东西:   - 对于1&#39; st ImageView:

android:paddingLeft="10dp"
android:paddingRight="5dp"
  • 用于2&#image ImageView:

    机器人:paddingLeft =&#34; 5DP&#34;

    机器人:paddingRight =&#34; 10dp&#34;

答案 1 :(得分:0)

添加到左侧的那个:

android:marginRight="5dp"

android:marginLeft="20dp"

添加到右边的那个:

android:marginLeft="5dp"

android:marginRight="20dp"
