先写布局：

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    tools:context=".MainActivity">

<android.support.v7.widget.RecyclerView
    android:id="@+id/RecyclerView_id"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</LinearLayout>

 adpter_item_layout.xml:

<?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">

    <LinearLayout

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/ImageView_id"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:src="@mipmap/ic_launcher_round"/>

        <TextView
            android:id="@+id/TextView_id"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="标题"/>
    </LinearLayout>

</LinearLayout>

 加权限导依赖：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.bwie.dome1">
    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".v.MyActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
