I have a requirement where the view needs to be at the center of bottom and adjust the height based on its content. So created constraint layout inside root constraint layout to acheive this. But now I am facing a problem with animation. I am not able to apply constraintSet.
<androidx.constraintlayout.widget.ConstraintLayout>
<androidx.constraintlayout.widget.ConstraintLayout
android:id="@+id/error_layout"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="12dp"
android:layout_marginEnd="12dp"
android:layout_marginBottom="40dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
<View
android:id="@+id/error_view"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:background="@drawable/display_result"
android:padding="24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="@+id/error_try_again"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="12dp"
android:background="@drawable/primary_button"
android:paddingLeft="12dp"
android:paddingRight="12dp"
android:text="@string/try_again"
android:textAlignment="center"
app:layout_constraintLeft_toLeftOf="@+id/error_view"
app:layout_constraintRight_toRightOf="@+id/error_view"
app:layout_constraintTop_toBottomOf="@+id/error_msg" />
<TextView
android:id="@+id/error_msg"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="@string/error_msg"
android:textAlignment="center"
app:layout_constraintTop_toBottomOf="@+id/empty_space_1"
app:layout_constraintLeft_toLeftOf="@+id/error_view"
app:layout_constraintRight_toRightOf="@+id/error_view"
/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
- If I need to go with
constraintSethow to restructure my layout (without nested groups)? - Is there any other way we can achieve like
sceneormotion layout. I am not sure about this implementation. But I feel likeconstraintSetis much straight forward to use.
from How to animate the nested view on constraint layout?
