如何通过java给gridview之间的空间 [英] How to give space between gridview in through java

问题描述

如何在GridView项目之间完美对齐，我已经添加了使用java的gridview，并且它的基础适配器已设置为添加了图像和textview。 > Xml代码：

 < android.support.v7.widget.CardView 
 android：layout_width =180dp 
 android：layout_height =200dp
 android：layout_margin =5dp
 android：orientation =vertical
 app：cardCornerRadius =5dp
 app： cardElevation = 5DP > 
 
< LinearLayout 
 android：layout_width =match_parent
 android：layout_height =match_parent
 android：orientation =vertical> 
 
< LinearLayout 
 android：layout_width =match_parent
 android：layout_height =match_parent
 android：layout_weight =1
 android：取向= 垂直 > 
 
< ImageView 
 android：id =@ + id / ImageWomenItem
 android：layout_width =match_parent
 android：layout_height =match_parent
 android：clickable =true
 android：scaleType =fitXY
 android：src =@ drawable / womenone/> 
< / LinearLayout> 
 
 $ b< TextView 
 android：id =@ + id / itemName
 android：layout_width =wrap_content
 android：layout_height = wrap_content
 android：text =Red Top
 android：textColor =＃8e8d8d
 android：textSize =15dp/> 
 
< / LinearLayout> 
 
< /android.support.v7.widget.CardView> 
  

这是Activity代码，我在其中声明了recylerview并将其设置为适配器

Java代码：

  recyclerView =（RecyclerView）view.findViewById（R.id.recyclerViewClothes） ; 
 recyclerView.setHasFixedSize（true）; 
 mLayoutManager = new GridLayoutManager（getActivity（），2）; 
 recyclerView.setLayoutManager（mLayoutManager）; 
 
 mAdapter = new GridAdapter（）; 
 recyclerView.setAdapter（mAdapter）; 
  

解决方案

为适配器xml的根布局添加填充。

 < LinearLayout 
 android：layout_width =match_parent
 android：layout_height =match_parent
 android：orientation =vertical
 android：padding =8dp> 
 
< android.support.v7.widget.CardView 
 app：cardCornerRadius =5dp
 app：cardElevation =5dp
 android：layout_width = 180dp
 android：layout_height =200dp
 android：layout_margin =5dp
 android：orientation =vertical> ....... 
< /android.support.v7.widget.CardView> 
 
< / LinearLayout> 
  

How do i get perfect aligning between the gridView items, i have added the gridview using java and it's base adapter is set in which i added the image and textview.

Xml Code:

    <android.support.v7.widget.CardView 
        android:layout_width="180dp"
        android:layout_height="200dp"
        android:layout_margin="5dp"
        android:orientation="vertical"
        app:cardCornerRadius="5dp"
        app:cardElevation="5dp">

 <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_weight="1"
                android:orientation="vertical">

                <ImageView
                    android:id="@+id/ImageWomenItem"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:clickable="true"
                    android:scaleType="fitXY"
                    android:src="@drawable/womenone" />
            </LinearLayout>


                <TextView
                    android:id="@+id/itemName"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="Red Top"
                    android:textColor="#8e8d8d"
                    android:textSize="15dp" />

        </LinearLayout>

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

This is Activity code in which i declared the recylerview and set it's adapter

Java code:

recyclerView = (RecyclerView) view.findViewById(R.id.recyclerViewClothes);
        recyclerView.setHasFixedSize(true);
             mLayoutManager = new GridLayoutManager(getActivity(), 2);
        recyclerView.setLayoutManager(mLayoutManager);

        mAdapter = new GridAdapter();
        recyclerView.setAdapter(mAdapter);

解决方案

Add padding to your root layout of adapter xml.

<LinearLayout     
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="8dp">

<android.support.v7.widget.CardView
    app:cardCornerRadius="5dp"
    app:cardElevation="5dp"
    android:layout_width="180dp"
    android:layout_height="200dp"
    android:layout_margin="5dp"
    android:orientation="vertical">.......
</android.support.v7.widget.CardView>

 </LinearLayout>
