How to set transparent background for image button, text edit, etc on android project.

When you want to change layout like that, somepeople add some code on file.java, but I have simple trick to change background of image button or EditText to transparant, it easy...you can add it's code android:background="#00ffffff" to your file.xml example:

Before:
<EditText
        android:id="@+id/I1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_x="1dp"
        android:layout_y="86dp"
        android:ems="10"
        android:gravity="center"
        android:hint="Input First Number"
        android:numeric="integer"
        android:textColorHint="#FAFAD2"
        android:textColor="#FAFAD2" />

After:
<EditText
        android:id="@+id/I1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_x="1dp"
        android:layout_y="86dp"
        android:background="#00ffffff"
        android:ems="10"
        android:gravity="center"
        android:hint="Input First Number"
        android:numeric="integer"
        android:textColorHint="#FAFAD2"
        android:textColor="#FAFAD2" />

save and run your project, and see the magic :D
okay...#keep coding, and be a programmer....
