android 4.4中与RecyclerView的对齐问题

I am implementing a RecyclerView in my application and it is working. But i am facing a problem with the list item alignment in Recyclerview.

我正在我的应用程序中实现RecyclerView,它正在工作。但我在Recyclerview中遇到列表项对齐问题。

actually my list item have a image view and a text view. i need some space between the each list item. like this

实际上我的列表项有一个图像视图和一个文本视图。我需要在每个列表项之间留出一些空间。像这样

With this Relative layout i am able to get my expected result. But for spacing between the items i used the RecyclerView.ItemDecoration

通过这种相对布局,我能够得到我期望的结果。但是对于我使用RecyclerView.ItemDecoration的项目之间的间距

Here is my list_view.xml

这是我的list_view.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="match_parent"
    android:background="#65FF0000"
    android:padding="10dip" >

    <ImageView
        android:id="@+id/item_icon"
        android:layout_width="70dip"
        android:layout_height="70dip"
        android:layout_centerVertical="true" />

    <TextView
        android:id="@+id/item_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_marginLeft="10dip"
        android:layout_toRightOf="@+id/item_icon"
        android:gravity="left"
        android:textSize="24sp" />

</RelativeLayout> 

insted of using the RecyclerView.ItemDecoration i tried the in the below way but it is not worked.Here is my list_item.xml code

我使用了RecyclerView.ItemDecoration但是我尝试了以下方式,但它没有用。这是我的list_item.xml代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#90FF0000"
        android:orientation="horizontal"
        android:weightSum="1" >

        <ImageView
            android:id="@+id/item_icon"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="0.4"
            android:src="@drawable/ic_launcher" />

        <TextView
            android:id="@+id/item_title"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight="0.6"
            android:text="TextView"
            android:textColor="@android:color/darker_gray"
            android:textSize="24dp" />
    </LinearLayout>

    <TextView
        android:id="@+id/textView1"
        android:layout_width="match_parent"
        android:layout_height="5dp"
        android:text=""
        android:textColor="#90FFFFFF" />

</LinearLayout>  

But i am getting the view like below

但我得到的观点如下

Where exactly i am making the mistake.. Thanks in advance

Well finally, I got the solution for my question.

最后,我得到了我的问题的解决方案。

In my RecyclerView adapter previously i used the below type of approach to create the list items

在我之前的RecyclerView适配器中,我使用以下类型的方法来创建列表项

 public MyAdapter.ViewHolder onCreateViewHolder( ViewGroup parent,
            int viewType )
    {
         // create a new view
        itemLayoutView = LayoutInflater.from( parent.getContext() ).inflate( R.layout.list_row_serch,
                                                                             null );

        // create ViewHolder
        ViewHolder viewHolder = new ViewHolder( itemLayoutView );

        return viewHolder;
    }

After changing it as like below it is working fine. even if it a Releative/Linear layout

更改后如下所示它工作正常。即使它是一个Releative / Linear布局

  public MyAdapter.ViewHolder onCreateViewHolder( ViewGroup parent,
            int viewType )
    {

        itemLayoutView = LayoutInflater.from( parent.getContext() ).inflate( R.layout.list_row_serch,
                                                                             parent,
                                                                             false );

        // create ViewHolder
        ViewHolder viewHolder = new ViewHolder( itemLayoutView );

        return viewHolder;
    }

So as I understand from your question you want your RecyclerView's items to look like this:

因此,我从您的问题中了解到,您希望RecyclerView的项目如下所示:

Here is a simple layout which will create this look (using RelativeLayout):

这是一个简单的布局,它将创建这个外观(使用RelativeLayout):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="match_parent"
                android:padding="10dip">

    <ImageView
        android:id="@+id/user_avatar"
        android:layout_width="70dip"
        android:layout_height="70dip"
        android:layout_centerVertical="true"/>

    <TextView
        android:id="@+id/username"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_marginLeft="10dip"
        android:layout_toRightOf="@+id/user_avatar"
        android:gravity="left"/>

</RelativeLayout>

and here is the version using LinearLayout :

这是使用LinearLayout的版本:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="horizontal"
              android:padding="10dip">

    <ImageView
        android:id="@+id/user_avatar"
        android:layout_width="70dip"
        android:layout_height="70dip"
        android:layout_gravity="center_vertical"/>

    <TextView
        android:id="@+id/username"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dip"
        android:layout_gravity="center_vertical"
        android:gravity="left"/>

</LinearLayout>

If you want space between two RecyclerView items no need to add another TextView just include padding to your main container in list_item.xml

如果您想在两个RecyclerView项目之间留出空间,则无需添加另一个TextView,只需在list_item.xml中包含填充到主容器中

#3

You will need to make the list item fill the whole width of its parent.

您需要使列表项填充其父级的整个宽度。

As below:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    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:background="#90FF0000"
        android:orientation="horizontal">

        <ImageView
            android:layout_weight="1"
            android:id="@+id/item_icon"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" />

        <TextView
            android:layout_weight="1"
            android:id="@+id/item_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="TextView"
            android:textColor="@android:color/darker_gray"
            android:textSize="24dp" />

        <TextView
            android:layout_weight="1"
            android:id="@+id/textView1"
            android:layout_width="match_parent"
            android:layout_height="5dp"
            android:text=""
            android:textColor="#90FFFFFF" />
    </LinearLayout>

</LinearLayout>
