To create a linear layout in which each child uses the same amount of space on the screen, set the android:layout_height of each view to "0dp" (for a vertical layout) or the android:layout_width of each view to "0dp" (for a horizontal layout). Then set the android:layout_weight of each view to "1" .
To center align LinearLayout, assign android:gravity attribute of this LinearLayout with the value “center”. Let us create an Android application with LinearLayout containing two Button widgets as children. We shall center align these children using gravity attribute.
If in linearlayout your orientation vertical, you can put the textview in the "horizontal center" by android:layout_gravity="center" . For centering textview vertically you need to set layout_height of textview to match_parent and set android:gravity to "center".
You can set the android:layout_weight='1' and both buttons will share the screen equally(side by side) or if you want the extra space between them, you can place a button each in a linear layout and set the android:layout_gravity to left and right for each.
Try to add empty View inside horizontal LinearLayout before element that you want to see right, e.g.:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
Do not change the gravity of the LinearLayout to "right" if you don't want everything to be to the right.
Try:
fill_parent
right
Code:
<TextView
android:text="TextView"
android:id="@+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right">
</TextView>
As a supplement to alcsan's answer, you can use Space since API 14 (Android 4.0 ICE_CREAM_SANDWICH), document here.
Space is a lightweight View subclass that may be used to create gaps between components in general purpose layouts.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<Space
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:gravity="right" />
</LinearLayout>
For apps that supporting API levels under 14, there is an android.support.v4.widget.Space since Android Support Library r22.1.0.
With Linear Layout
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/select_car_book_tabbar"
android:gravity="right" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:src="@drawable/my_booking_icon" />
</LinearLayout>
with FrameLayout
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/select_car_book_tabbar">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|right"
android:src="@drawable/my_booking_icon" />
</FrameLayout>
with RelativeLayout
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/select_car_book_tabbar">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerInParent="true"
android:src="@drawable/my_booking_icon" />
</RelativeLayout>
setting the view's layout_weight="1" would do the trick.!
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" />
<RadioButton
android:id="@+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
