（Android）listview分隔符已删除，但单击后仍显示蓝线

Question

I have a listview in a LinearLayout, and i have removed its divider in xml, like this:

   <LinearLayout 
        android:layout_width="match_parent"
        android:layout_height="140dp"
        android:orientation="vertical"
        android:background="@drawable/main_content">
        <ListView 
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:cacheColorHint="@null"
            android:divider="@null"
            android:dividerHeight="0dp"/>
     </LinearLayout>

The problem is, everytime when i click an item, a blue line will show up above the item just like a divider exists there. Then if i click somewhere else, the line goes away. How can i stop this from happening?

Answer 1

use list Selector property as below:

android:listSelector="#00000000"

you can set it to null as well. i have set it to transparent.

Answer 2

Add these two lines inside your listview

android:drawSelectorOnTop="false"
android:listSelector="@android:color/transparent"

and delete

android:cacheColorHint="@null"
android:divider="@null"
android:dividerHeight="0dp"

Answer 3

use

<ListView 
android:layout_width="match_parent"
android:layout_height="match_parent"
android:drawSelectorOnTop="false"
android:listSelector="@android:color/transparent"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"/>
