2 ListView 之每一个 item 的布局 item_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="45dp"
android:orientation="horizontal"
tools:ignore="HardcodedText,NestedWeights"
>
<ImageView
android:id="@+id/image"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="4"
android:contentDescription="头像"
android:src="@drawable/ic_menu_send"
/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="24"

</LinearLayout>
3 ListView 之 item 颜色选择器 on_item_selected.xml （放在 drawable 文件夹里）
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="false" android:drawable="@android:color/black"/>
