Disable button with button selector

问题

I have a button selector that changes the button image when it is pressed. I have also set an image for when the button is disabled. I try and disable the button programmatically but the disabled button image is not appearing. Is my button_selector correct?

<item android:drawable="@drawable/red_btn_bg_disabled" android:state_enabled="false"/> <!-- disabled -->

<item android:drawable="@drawable/red_btn_bg_pressed" android:state_pressed="true"/> <!-- pressed -->
<item android:drawable="@drawable/red_btn_bg_pressed" android:state_focused="true"/> <!-- focused -->

<item android:drawable="@drawable/red_btn_bg"/> <!-- default -->

I am using mButton.setEnabled(false) in my code to disable the button

try this one and i uploaded one sample project for you for more help check the project

selector.xml

   <selector xmlns:android="http://schemas.android.com/apk/res/android">

        <item android:drawable="@drawable/btn_disable" android:state_enabled="false"/>
        <item android:drawable="@drawable/btn_pressed" android:state_pressed="true"/>
        <item android:drawable="@drawable/btn_normal"/>

    </selector>

and use this selector in button as following

<Button
         android:id="@+id/button1"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_alignLeft="@+id/button1"
         android:layout_below="@+id/button1"
         android:layout_marginTop="30dp"
         android:background="@drawable/selector"
         android:enabled="false"
         android:text="Disable Button" />

Try this.

<item android:drawable="@drawable/red_btn_bg_pressed" android:state_pressed="true"/> <!-- pressed -->

<item android:drawable="@drawable/red_btn_bg_disabled" android:state_enabled="false"/> <!-- disabled -->

<item android:drawable="@drawable/red_btn_bg"/> <!-- default -->
