Android: textColor of disabled button in selector not showing?

问题

I am trying to make a button with a selector my button can have the following states:

Enabled/Disabled
Pressed/Not Pressed

According to the states mentioned above. I need to manipulate the button's:

Text color
background image

The button starts off my being disabled so it should have the disabled textColor and the disabled button background. But I can see the default textColor (specified in style) and NO background image!

Here is my selector button_selector.xml

<?xml version="1.0" encoding="utf-8"?>

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

    <item android:state_pressed="false"
        android:state_enabled="false"
        android:textColor="#9D9FA2"
        android:drawable="@drawable/button" />    

    <item android:state_pressed="true"
        android:state_enabled="true"
        android:drawable="@drawable/button_pressed"/>

    <item android:state_pressed="true"
        android:state_enabled="false"
        android:textColor="#9D9FA2"
        android:drawable="@drawable/button"/>

    <item android:state_pressed="false"
        android:state_enabled="true"
        android:drawable="@drawable/button"/>    

</selector>

And here is my button declaration in the my layout.xml

    <Button android:id="@+id/reserve_button"
        android:text="@string/reserve_button"
        android:layout_width="120dp"
        android:layout_height="40dp"
        android:layout_marginTop="10dp"
        android:layout_marginLeft="20dp"
        android:paddingRight="15dp"
        android:layout_gravity="left"
        style="@style/buttonStyle"
        android:background="@drawable/button_selector" />

And finally this is my style (where my default textColor is set)

<?xml version="1.0" encoding="utf-8"?>

 <resources>

     <style name="buttonStyle">
      <item name="android:textStyle">bold</item>
      <item name="android:textColor">#282780</item>
      <item name="android:textSize">18sp</item>
     </style>

</resources>

Please help!

You need to also create a ColorStateList for text colors identifying different states.

Do the following:

Create another XML file in res\color named something like text_color.xml.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <!-- disabled state -->
  <item android:state_enabled="false" android:color="#9D9FA2" /> 
  <item android:color="#000"/>
</selector>

In your style.xml, put a reference to that text_color.xml file as follows:

<style name="buttonStyle" parent="@android:style/Widget.Button">
  <item name="android:textStyle">bold</item>
  <item name="android:textColor">@color/text_color</item>
  <item name="android:textSize">18sp</item>
</style>

This should resolve your issue.

1.Create a color folder in /res/ folder and in color folder create on xml:

text_color_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <!-- disabled state --> 
<item android:state_enabled="false" android:color="#776678" /> 
 <item android:color="#ffffff"/>
</selector>

2.Now Create a xml layout:-

 <Button

        android:id="@+id/button_search"

        android:layout_width="652dp"

        android:layout_height="48dp"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:layout_marginTop="18dp"

        android:background="@android:color/transparent"

        android:text="Hello Bhaskar"

        android:textColor="@color/text_color_selector"/>

The most easy solution is to set color filter to the background image of and button as I saw here

You can do as follow:

if ('need to set button disable')
    button.getBackground().setColorFilter(Color.GRAY, PorterDuff.Mode.MULTIPLY);
else
    button.getBackground().setColorFilter(null);

Hope I helped someone...

<Button android:id="@+id/reserve_button"
        android:text="@string/reserve_button"
        android:layout_width="120dp"
        android:layout_height="40dp"
        android:layout_marginTop="10dp"
        android:layout_marginLeft="20dp"
        android:paddingRight="15dp"
        android:layout_gravity="left"
        style="@style/buttonStyle"
        android:background="@drawable/button_selector" />

I cannot see diabling of your button in your layout xml. add this to your button layout.

android:enabled="false"

so your Button layout will be,

<Button android:id="@+id/reserve_button"
        android:text="@string/reserve_button"
        android:layout_width="120dp"
        android:layout_height="40dp"
        android:layout_marginTop="10dp"
        android:layout_marginLeft="20dp"
        android:enabled="false"
        android:paddingRight="15dp"
        android:layout_gravity="left"
        style="@style/buttonStyle"
        android:background="@drawable/button_selector" />

You can create a color list

file location:

res/color/filename.xml

The filename will be used as the resource ID.

resource reference:

In Java: R.color.filename

In XML: @[package:]color/filename

syntax:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:color="hex_color"
        android:state_pressed=["true" | "false"]
        android:state_focused=["true" | "false"]
        android:state_selected=["true" | "false"]
        android:state_checkable=["true" | "false"]
        android:state_checked=["true" | "false"]
        android:state_enabled=["true" | "false"]
        android:state_window_focused=["true" | "false"] />
</selector>

Example:

XML file saved at res/color/button_text.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
          android:color="#ffff0000"/> <!-- pressed -->
    <item android:state_focused="true"
          android:color="#ff0000ff"/> <!-- focused -->
    <item android:color="#ff000000"/> <!-- default -->
</selector>

This layout XML will apply the color list to a View:

<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/button_text"
    android:textColor="@color/button_text" />
