How to apply shape and selector simultaneously for Button?

Question

I have applied a shape for a button like:

Answer 1

Detailed to the point answer

Create a color resource in

res/values/colors.xml

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


    <item name="yellow" type="color">#F7B500</item>
    <item name="yellow_dark" type="color">#AC7E00</item>

    <integer-array name="androidcolors">
        <item>@color/yellow</item>
        <item>@color/yellow_dark</item>
    </integer-array>

</resources>

Create a drawable at

res/drawable/bg_yellow_round.xml

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

    <solid android:color="@color/yellow" />

    <stroke
        android:width="2dp"
        android:color="@color/yellow" />

    <corners
        android:bottomLeftRadius="20dp"
        android:bottomRightRadius="20dp"
        android:topLeftRadius="20dp"
        android:topRightRadius="20dp" />

</shape>

Create another drawable, you want for transition at same place and name it

res/drawable/bg_yellow_dark_round.xml

<solid android:color="@color/yellow_dark" />

<stroke
    android:width="2dp"
    android:color="@color/yellow_dark" />

<corners
    android:bottomLeftRadius="20dp"
    android:bottomRightRadius="20dp"
    android:topLeftRadius="20dp"
    android:topRightRadius="20dp" />

Now create a color state list at

res/color/btn_selector_yellow.xml

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

    <item android:drawable="@color/yellow" android:state_focused="true" android:state_pressed="false"/>
    <item android:drawable="@drawable/bg_yellow_dark_round" android:state_pressed="true"/>
    <item android:drawable="@drawable/bg_yellow_round"/>

</selector>

Now set it to your button as following

<Button
                android:id="@+id/button1"
                android:layout_width="248dp"
                android:layout_height="44dp"
                android:layout_gravity="center_horizontal"
                android:layout_marginBottom="10dp"
                android:layout_marginTop="20dp"
                android:background="@color/btn_selector_yellow"
                android:text="AZ_ is so cool" />

Now this will do transition from

to

.

Answer 2

Well I know it's way too late But here is a solved example

 <TextView
            android:id="@+id/txt_out_going_calls"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="04dp"
            android:layout_weight="1"
            android:background="@drawable/header_text_view_selector"
            android:gravity="center"
            android:text="@string/outgoing_calls_tab_button_text"
            android:textColor="@color/home_text_color" />

and my header_text_view_selector

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

        <shape xmlns:android="http://schemas.android.com/apk/res/android">
            <solid android:color="@color/home_fragment_tab_color_selected"/>
            <corners android:radius="25dip" />
            <padding android:bottom="08dip" android:left="9dip" android:right="9dip" android:top="08dip" />
        </shape>
    </item>
    <item android:state_selected="false">

        <shape>
            <solid android:color="@color/home_fragment_tab_color_simple"/>
            <corners android:radius="25dip" />
            <padding android:bottom="08dip" android:left="9dip" android:right="9dip" android:top="08dip" />
        </shape>
    </item>
</selector>

So basically i m creating a rounded textview with selector. Here i m handling only state_selected and not_selected. Hope it helps

This is my way, and it works!

<item android:state_pressed="true">

    <shape android:shape="oval">


        <gradient android:centerX=".6"
            android:centerY=".40"
            android:endColor="@color/colorPrimary"
            android:gradientRadius="20"
            android:startColor="@color/colorPrimary"
            android:type="radial" />

        <stroke android:width="1dp"
            android:color="#FFFFFF" />

        <size android:width="55dp"
            android:height="55dp" />

    </shape>
</item>

<item android:state_focused="false">
    <shape android:shape="oval">


        <gradient android:centerX=".6"
            android:centerY=".40"
            android:endColor="@android:color/transparent"
            android:gradientRadius="20"
            android:startColor="@android:color/transparent"
            android:type="radial" />

        <stroke android:width="1dp"
            android:color="#FFFFFF" />

        <size android:width="55dp"
            android:height="55dp" />

    </shape>
</item>

Answer 4

use this way:

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

   <item android:state_pressed="true" >
       <shape>.......</shape>
   </item>
   ..........
   ..........
</selector>

Answer 5

You can also create a shape that is using a selector inside. If your shape is just changing its color in different states, this is a lot cleaner.

color/color_selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/blue_dark" android:state_pressed="true" />
    <item android:color="@color/blue_light" />
</selector>

drawable/shape.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/color_selector" />
    <corners android:bottomLeftRadius="6dip" android:bottomRightRadius="6dp" />
    <padding android:bottom="0dip" android:left="0dip" android:right="0dip" android:top="0dip" />
</shape>

Answer 6

Use your shape name as you use any image and use it selector as you use image. Try out you will not face any problem. Is that what you were asking?
