Question

I want to change all EditText UI In android. For example I want to change On Focus, On Blur and … style. How can I do it? Actually I read some snippet, but I don’t understand what they do!

Answer 1

1- create selector for different state

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_window_focused="false" android:state_enabled="true" android:drawable="@drawable/textfield_default" />
  <item android:state_window_focused="false" android:state_enabled="false" android:drawable="@drawable/textfield_disabled" />
  <item android:state_pressed="true" android:drawable="@drawable/textfield_pressed" />
  <item android:state_enabled="true" android:state_focused="true" android:drawable="@drawable/textfield_selected" />
  <item android:state_enabled="true" android:drawable="@drawable/textfield_default" />
  <item android:state_focused="true" android:drawable="@drawable/textfield_disabled_selected" />
  <item android:drawable="@drawable/textfield_disabled" />
</selector>

2- To apply the customize drawable xml use the android:backgroung attibute of the EditText

android:background="@drawable/yourXml"
