Android: How to fill RelativeLayout to full width of screen?

android, android-layout, layout, xml

Solution

Replace this:

   android:layout_width="wrap_content"
   android:layout_height="wrap_content"

With

   android:layout_width="match_parent"
   android:layout_height="wrap_content"

into your `LinearLayout` or Remove all the Padding from main `RelativeLayout`

Problem

I am creating an Android app which has a main RelativeLayout and some LinearLayout within it. Now i have this problem. When dragging items to the editor, e.g. a LinearLayout, it doesn't fit to the full width of the screen. How can I make this possible? This is my XML: ``` <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" android:fillViewport="true" android:gravity="fill" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <LinearLayout android:id="@+id/itemDetailLayout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:orientation="vertical" android:fillViewport="true" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <ImageView android:id="@+id/itemImage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:minHeight="40dp" android:minWidth="40dp" android:src="@drawable/ic_launcher" /> <TextView android:id="@+id/itemName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="20dp" android:text="Name" android:textAppearance="?android:attr/textAppearanceMedium" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="match_parent" android:orientation="vertical" android:fillViewport="true" > <TextView android:id="@+id/itemRecentHigh" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Recent High" /> <TextView android:id="@+id/itemRecentLow" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Recent Low" /> <TextView android:id="@+id/itemAverage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Average" /> </LinearLayout> </LinearLayout> <LinearLayout android:id="@+id/listViewLayout" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@+id/itemDetailLayout" android:layout_marginTop="10dp" android:fillViewport="true" android:gravity="fill_horizontal" android:orientation="vertical" > <ListView android:id="@+id/searchListView" android:layout_width="match_parent" android:layout_height="fill_parent" android:fillViewport="true" > </ListView> </LinearLayout> ``` Added a screenshot for more info. Added blue background to have some contrast.
