Android: how to use selector?

Question

I have a problem of using selector that it does not work as what I expect. I wanna click on it then it gives me reaction and I select it(By long click but I probably do it t

Answer 1

What are you expecting? A reaction only when it's clicked?

Try removing removing:

android:state_selected="true" 

Edit: This should be your selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/my_drawable" android:state_selected="true"></item>
    <item android:drawable="@drawable/my_drawable" android:state_pressed="true"></item>
    <item android:drawable="@drawable/my_drawable"></item>

</selector>

What is the behaviour that you are experiencing?

Edit:

<LinearLayout 
     android:layout_weight="9"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:orientation="vertical"
     android:background="@drawable/selector_row"
     android:duplicateParentState=true>

I don't know if it actually solves the problem

Answer 2

Thank you to all brothers trying hard to answer me. I have got the answer....just simply by setting android:clickable="true" at LinearLayout. Ha, it's silly.....

I remember dude who provide relating information but I ignored... sorry to him.

Create an XML file and place it in the drawable folder. Open it and write the following code:

<selector
    xmlns:android="http://schemas.android.com/apk/res/android"
    >
    <item 
        android:drawable="YOUR IMAGE OR COLOR"

         android:state_pressed="true"/>
    <item
        android:drawable="YOUR IMAGE OR COLOR"

          android:state_selected="true"/>
    <item
        android:drawable="YOUR IMAGE OR COLOR"

           android:state_focused="true"/>

</selector>

Then in your main XML file, place android:background="@drawable/selector.xml"
