No Android development experience of friends, the realization of transparency is a certain difficulty, I see the Wheat College Android development video above three ways to achieve transparency, these three methods are very good, hey, you copy down to share to everyone.
1. Set Alpha
View v = Findviewbyid (r.id.content);/to the ID of the layout you want to set the transparent background
V.getbackground (). Setalpha (100);//0~255 Transparency Value
2, with ARGB to control
Translucent <button android:background= "#e0000000"/>
Transparent <button android:background= "#00000000"/>
3, with the Android system comes with the transparency effect
Android:background= "@android: Color/transparent"
For example, the Set button
<button android:background= "@android: Color/transparent"
android:text= "@+id/button01"
Android:id= "@+id/button01"
Android:layout_width= "Wrap_content"
android:layout_height= "Wrap_content"
Android:textcolor= "#ffffff"/>
