FrameLayout, how to move item under other item

Question

I create a layout with button, this button have logic and i dont want to integrate it.

So i think like:

When i have button, i need to add a char $, so i create a frameLayout and add here a TextView, i do this, but my TextView is under button, so i didnt see this TextView,

Here is my code:

  <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true">

        <Button
            android:id="@+id/button_cash"
            android:layout_width="80dp"
            android:layout_height="wrap_content"
            android:background="@drawable/button_radius"
            android:paddingRight="12dp"
            android:text="@string/_5000"
            android:textColor="@color/white"
            android:textSize="14sp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="right"
            android:layout_marginRight="14dp"
            android:layout_marginTop="15dp"
            android:text="@string/dollar_$"
            android:textColor="@color/white"
            android:textSize="14sp" />
    </FrameLayout>

And my question is, how to move item under other item in FrameLayout? Thanks for advice

Answer 1

This is probably due to the elevation parameter. By default a Button has a non-zero value of elevation while TextView's elevation is 0dp.

Try manipulating elevation (either increase elevation for TextView or decrease elevation for Button) to match your exact case.

I suggest you apply both:

app:elevation="<your_value_in_dp>"    
android:elevation="<your_value_in_dp>"
