android layout creation issue
android, android-layout, java
Solution
There is no real usage to have just a LinearLayout inside a RelativeLayout. So one of them is useless as this is redundant.
edit
This warning is triggered, when a Layout has only one child that is also a Layout. In this case one of both can be removed without any problems. It is recommended to remove these redundant layouts as they reduce the overall performance of the UI.
Problem
Am new to android development. I had created one android app and for that following is my main.xml ``` <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/bg" xmlns:android="http://schemas.android.com/apk/res/android"> <LinearLayout android:id="@+id/grid_layout_1" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" > <Button android:id="@+id/btnLogin" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/login_btn_text"/> <Button android:id="@+id/btnRegister" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/reg_btn_text"/> </LinearLayout> </RelativeLayout> ``` Am getting the following warning : ``` This LinearLayout layout or its RelativeLayout parent is possibly useless; transfer the background attribute to the other view ``` Can anyone tell the reason for this warning and a solution to the issue.?
