Note: Its build using ConstraintLayout. The sample is an alternative for nested layouts. Build to remove nested structure and create a flat xml layout, which eventually improves performance
Below example in created using ConstraintLayout
since percent support library is deprecated from API level 26.0.0.
This sample uses ConstraintLayout
to build xml UI. Helps to avoid the overhead of Nested layouts and thereby improving performance.
Really awesome!!!
Steps:
Add below into build.gradle
compile 'com.android.support.constraint:constraint-layout:1.1.0-beta3'
Add layout_constraintHeight_percent
and layout_constraintWidth_percent
to specify the percentage range.
Finally add layout_constraintWidth_default="percent"
and layout_constraintHeight_default="percent"
. Thats it !!!.
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/fifty_thirty"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#ffff8800"
android:gravity="center"
android:text="@string/fifty_fifty_text"
android:textColor="@android:color/white"
app:layout_constraintHeight_default="percent"
app:layout_constraintHeight_percent="0.5"
android:textSize="25sp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_default="percent"
app:layout_constraintWidth_percent="0.5" />
<TextView
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#ffff5566"
android:gravity="center"
android:text="@string/fifty_fifty_text"
android:textColor="@android:color/white"
android:textSize="25sp"
app:layout_constraintHeight_default="percent"
app:layout_constraintHeight_percent="0.5"
app:layout_constraintLeft_toRightOf="@id/fifty_thirty"
app:layout_constraintTop_toBottomOf="@id/fifty_thirty"
app:layout_constraintWidth_default="percent"
app:layout_constraintWidth_percent="0.5" />
</android.support.constraint.ConstraintLayout>
Bingo we are done !!!
