You can use LinearLayout
with weight
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/activity_landing"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.50"
android:text="1" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.25"
android:text="2" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.25"
android:text="3" />
</LinearLayout>
Or
You can use PercentRelativeLayout
