Android: How to place an animated image inside an EditText that we can show and hide.

Answer 1

With the work that you've already done, I think the easiest answer would be to change your LinearLayout to a RelativeLayout, so that you can set alignParentRight on the ImageView and add paddingRight as needed.

Another option is to create a custom view component: http://developer.android.com/guide/topics/ui/custom-components.html

Answer 2

I'd probably use a FrameLayout and do something like this:

<FrameLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    >
    <EditText
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="Some text..."
        />
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right|center_vertical"
        android:src="@drawable/...."
        />
</FrameLayout>

Notice the "layout_gravity" on the ImageView...
