Android center view in FrameLayout doesn't work

We can align a view in center of the FrameLayout by setting the layout_gravity of the child view.

In XML:

android:layout_gravity="center"

In Java code:

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.CENTER;

Note: use FrameLayout.LayoutParams not the others existing LayoutParams


I'd suggest a RelativeLayout instead of a FrameLayout.

Assuming that you want to have the TextView always below the ImageView I'd use following layout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerInParent="true"
        android:src="@drawable/icon"
        android:visibility="visible"/>
    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_below="@id/imageview"
        android:gravity="center"
        android:text="@string/hello"/>
</RelativeLayout>

Note that if you set the visibility of an element to gone then the space that element would consume is gone whereas when you use invisible instead the space it'd consume will be preserved.

If you want to have the TextView on top of the ImageView then simply leave out the android:layout_alignParentTop or set it to false and on the TextView leave out the android:layout_below="@id/imageview" attribute. Like this.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="false"
        android:layout_centerInParent="true"
        android:src="@drawable/icon"
        android:visibility="visible"/>
    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:gravity="center"
        android:text="@string/hello"/>
</RelativeLayout>

I hope this is what you were looking for.


Just follow this order

You can center any number of child in a FrameLayout.

<FrameLayout
    >
    <child1
        ....
        android:layout_gravity="center"
        .....
        />
    <Child2
        ....
        android:layout_gravity="center"
        />
</FrameLayout>

So the key is

adding android:layout_gravity="center"in the child views.

For example:

I centered a CustomView and a TextView on a FrameLayout like this

Code:

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
    <com.airbnb.lottie.LottieAnimationView
        android:layout_width="180dp"
        android:layout_height="180dp"
        android:layout_gravity="center"
        app:lottie_fileName="red_scan.json"
        app:lottie_autoPlay="true"
        app:lottie_loop="true" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:textColor="#ffffff"
        android:textSize="10dp"
        android:textStyle="bold"
        android:padding="10dp"
        android:text="Networks Available: 1\n click to see all"
        android:gravity="center" />
</FrameLayout>

Result:
