Question

So I have an xml layout im using and it has two main elements, a framelayout that houses a camera preview, and a imageview. The image view is supposed to be visible over the framelayout and it is until the camerapreview is turned on then it gets pushed behind it. What am i doing wrong?

I’ve done a lot of testing removing elements from the layout and rebuilding and i cant seem to fix the cause of the error, i believe the cause must be somewhere in the code.

I think is supposed to get push behind it because is a RelativeLayout. I think you should use a LinearLayout. Also the attribute android:layout_weight="1" is an invalid parameter in RelativeLayout.

You can try and force the image view to align top:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="390dip" 
    android:layout_marginTop="25dip">        

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="300dip"
        android:layout_height="305dip"
        android:background="#00000000"
        android:layout_alignParentTop="true"
        android:src="@drawable/try_3"
        android:visibility="visible" 
        android:layout_marginLeft="10dip"/>

    <FrameLayout
        android:id="@+id/previewframe1"
        android:layout_width="320dip"
        android:layout_height="310dip"
        android:layout_alignParentTop="true"
         >
    </FrameLayout>

</RelativeLayout>

Hope that helps.
