问题
i am trying to change the color of text inside a button.
So for example i have a button which is filled with white and the text is blue. When i click on the button i want these two colors to swap (text inside the button becomes white and the button blue).
I have tried something like this:
<item style="@style/ButtonText_Menue_Clicked" android:drawable="@drawable/button_menue_default" android:state_focused="true"></item>
<item style="@style/ButtonText_Menue" android:drawable="@drawable/button_menue_default" ></item>
but it actually does nothing. Is there any way to do what i want, or do i have to do some stuff in the onclik event (but then there is the problem how to set the colors back when the "click is gone" )
回答1:
Create a selector
resource in res/color
for the text color and a button selector
in res/drawable
as below...
text_color.xml
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:color="#800000" />
<item
android:state_pressed="false"
android:color="#4C5" />
</selector>
button_color.xml
<?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="rectangle">
<solid android:color="#4C5"/>
</shape>
</item>
<item
android:state_pressed="false">
<shape android:shape="rectangle" >
<solid android:color="#800000"/>
</shape>
</item>
</selector>
Add the button to the layout
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:textColor="@color/text_color"
android:background="@drawable/button_color"/>
