为Checkbox for Android更改已选中和未选中的图标

Question

Instead of having a check mark for the icon, I want a custom star (I have checked and unchecked icons). Can this be done through a property? Or must I declare a custom widget that derives from Checkbox?

Answer 1

Kind of a mix:

Set it in your layout file :-

 <CheckBox android:layout_width="wrap_content"
           android:layout_height="wrap_content" 
           android:text="new checkbox"
           android:background="@drawable/checkbox_background" 
           android:button="@drawable/checkbox" />

where the @drawable/checkbox will look like:

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

<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_checked="true" android:state_focused="true"
  android:drawable="@drawable/checkbox_on_background_focus_yellow" />
 <item android:state_checked="false" android:state_focused="true"
  android:drawable="@drawable/checkbox_off_background_focus_yellow" />
 <item android:state_checked="false"
  android:drawable="@drawable/checkbox_off_background" />
 <item android:state_checked="true"
  android:drawable="@drawable/checkbox_on_background" />
</selector>

Answer 2

这是android:button="@drawable/selector_checkbox"让它工作

Answer 3

I realize this is an old question, and the OP is talking about using custom gx that aren't necessary 'checkbox'-looking, but there is a fantastic resource for generating custom colored assets here: http://kobroor.pl/

Just give it the relevant details and it spits out graphics, complete with xml resources, that you can just drop right in.

Answer 4

One alternative would be to use a drawable/textview instead of a checkbox and manipulate it accordingly. I have used this method to have my own checked and unchecked images for a task application.
