clipChildren is not working even though set to false?

Question

In my application I am trying to move images using animation. When I try to animate the image is cutting even though I use clipChildren false in every xml block

    <RelativeLayout
        android:id="@+id/baselayout"
        android:layout_width="match_parent"
        android:layout_height="120dp"
        android:layout_alignParentRight="true"
        android:layout_below="@+id/imageView1"
        android:clipChildren="false"
        android:clipToPadding="false" >

Answer 1

One of the parents of your RelativeLayout might be clipping children (sometimes compatibility libraries add a mystery ViewGroup such as NoSaveStateFrameLayout for example). I've used something like this in the past with success to disable clip on all parents of a view:

public void disableClipOnParents(View v) {
    if (v.getParent() == null) {
        return;
    }

    if (v instanceof ViewGroup) {
        ((ViewGroup) v).setClipChildren(false);
    }

    if (v.getParent() instanceof View) {
        disableClipOnParents((View) v.getParent());
    }
}

I know its late, but this is the simplest complete answer:

just put on every layout :

    android:clipChildren="false"
    android:clipToPadding="false"

Note @roflharrison mentioned: this won't work in the cases where the operating system wraps/injects your view in ViewGroup's that's aren't in your layout

The final reason is "RelativeLayout". So to solve it, don't use RelativeLayout as your Larger-than-parent control's parent. FrameLayout instead, like:

<!-- it's ok as grand parent -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:clipChildren="false">

    <!-- parent must not be a RelativeLayout -->
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="38dp"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="9dp">

        <!-- Your Larger-than-parent View -->
        <View
            android:layout_width="56dp"
            android:layout_height="138dp"
            android:layout_gravity="center"
            android:background="@android:color/black" />

    </FrameLayout>

</RelativeLayout>

The idea of @roflharrison is quite good, however, the codes has some problem: Here we disable clipChildren recursively, but when we reached the root view, it's v.getParents() would be null, the method returns immediately, and its ClipChildren attribute won't be disabled.

What's more, for the following line:

if (v.getParent() instanceof View)

?? Shouldn't the parent of the view be a ViewGroup? And shouldn't we disable ViewGroup's clip attributes, not View's? So I change the code to the following, and it worked quite well:

public void disableClipOnParents(View v) {
    if (v == null) {
        return;
    }
    if (v instanceof ViewGroup) {
        ((ViewGroup) v).setClipChildren(false);
    }
    disableClipOnParents((View) v.getParent());
}
