LinearLayout put child at the right side
My way (using a RelativeLayout):
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView
android:id="@+id/productPriceTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Rs 3579.0"
/>
<Button
android:id="@+id/buyNowButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Buy Now"
/>
</RelativeLayout>
See how I explicitly align the TextView to the Parent's left side and the Button to the Parent's right side
You can then center the TextView vertically in the RelativeLayout, by setting:
android:layout_centerVertical="true"
in the TextView itself
Newr OS versions may prefer this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView
android:id="@+id/productPriceTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:text="Rs 3579.0"
/>
<Button
android:id="@+id/buyNowButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:text="Buy Now"
/>
</RelativeLayout>
Try below xml:
<?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="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/productPriceTextView1"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:text="Rs 3579.0"
/>
<Button
android:id="@+id/buyNowButton1"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="Buy Now" />
</LinearLayout>
There is a cleaner way to do this, using LinearLayout : just give the left element a width of 0 and a weight of 1, and set the right one's width on wrap_content. And that's it!
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/productPriceTextView1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Rs 3579.0"
/>
<Button
android:id="@+id/buyNowButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Buy Now" />
</LinearLayout>
