如何同时应用形状和选择器的按钮？

小开

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?

最佳答案

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>

shape.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/star_off"/>
<corners android:radius="5dp"/>
<padding android:left="0dp" android:top="0dp" android:right="0dp" android:bottom="0dp" />
</shape>

selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="@android:integer/config_mediumAnimTime">


<item android:drawable="@color/tab_focused" android:state_focused="true" android:state_pressed="false"/>
<item android:drawable="@color/tab_pressed" android:state_pressed="true"/>

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 light yellow

to

dark yellow .

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>

My example is a circle button with state_pressed. code bellow:

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




<item android:state_pressed="true">
<shape android:shape="oval">
<solid android:color="@color/light_primary_color" />
</shape>


</item>
<item>
<shape android:shape="oval">
<solid android:color="@color/accent_color" />
</shape>
</item>


</selector>

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>

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

To be more reusable, you can set states on single properties. Avoid duplicating your shapes

<selector
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item>
<shape android:shape="rectangle" >
<corners android:radius="5dp"/>
<solid
android:state_enabled="false"
android:color="@color/transparent"
/>
<solid
android:state_enabled="true"
android:color="@color/background"
/>
<stroke
android:width="@dimen/dividerHeight"
android:color="@color/dividerLight"
/>
</shape>
</item>
</selector>

I was able to set background programmatically once disabled using this method.
