问题
Is it possible to make Radio Buttons in Android, where there are image representation to a button instead of a regular buttons? I want it to look something like that:
The cyan in the middle represents the selected button.
How can I do it?
回答1:
The RadioButton class has a buttonDrawable member, derived from CompoundButton.
There are multiple ways you can change this drawable.
From java:
myRadioButton.setButtonDrawable(resourceId or Drawable);
From xml:
<RadioButton
android:button="@drawable/yourdrawable"
...
/>
If you just want the checked/unchecked state look differently, then
- Add a new selector xml by rightclicking your res folder -> New -> Android xml -> select Drawable in the upper dropdown -> choose selector (in eclipse)
- To setup this selector, please take a look at this link
- From now on you can set your freshly created selector to any of your checkboxes/radiobuttons by using its id.
