Question

Hey I am trying to make a notification for my file uploading notification. This is my XML: but it keeps giving me the error: Circular dependencies cannot exist in RelativeLayout. What am I doing wrong? I dont see anything wrong with it? I was also trying to make it look similar to the browser downloader

<?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="fill_parent"
    android:padding="5dp">

    <RelativeLayout 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:id="@+id/left"
        android:layout_toLeftOf="@+id/right">

        <ImageView 
            android:id="@+id/status_icon"
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:layout_alignParentTop="true" 
        />

        <TextView 
            android:id="@+id/progress_text" 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" 
            android:layout_below="@+id/status_icon"
            android:text="0%"
        />


    </RelativeLayout>

    <RelativeLayout 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:id="@+id/right"
        android:layout_toRightOf="@+id/left">

        <TextView

            android:layout_width="fill_parent"
            android:layout_height="wrap_content" 
            android:layout_alignParentTop="true"

        <ProgressBar

            android:indeterminate="false" 
            android:indeterminateOnly="false" 
        />
    </RelativeLayout>
</RelativeLayout>

Answer 1

RelativeLayout “left” is trying to lay itself out based on the location of RelativeLayout “right”. This cannot be done, because as the exception says, it’s circular. How can you park a car based on the parking of another car if that car is still moving?

Based on your xml file, I recommend you use LinearLayouts. There really isn’t anything that you are doing here that can’t be solved with two LL’s and the parent RelativeLayout.
