Circular dependencies for XML

Question

I am a new android developer. When I run my app, I got this error :"rendering Problems Exception raised during rendering: Circular dependencies cannot exist in RelativeLayout (Details)" Can anyone help me with my XML code? Why I got Circular dependencies error?

Answer 1

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_marginTop="30dp"
    android:id="@+id/radioButtons"
    android:layout_marginLeft="50dp"
    android:layout_centerInParent="true">


</RelativeLayout>

You have android:layout_alignParentLeft="true" and android:layout_centerInParent="true" together and they are conflicting each other

Did you want android:layout_centerHorizontal="true" instead?

Also, based on the name of that RelativeLayout, it looks like you wanted to put radio buttons in that layout. so you might want to do

...
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginTop="30dp"
android:id="@+id/radioButtons"
android:layout_marginLeft="50dp"
android:layout_centerHorizontal="true">

    <Button
        android:typeface ="sans"
        android:background="@drawable/roundcornor_button"
        android:layout_width="300dp"
        android:textAllCaps="false"
        android:layout_height="wrap_content"
        android:text="Submit"
        android:textColor="@color/black"
        android:id="@+id/submitButton"
        android:backgroundTint="@color/gold"

        android:layout_centerHorizontal="true"
        android:layout_marginBottom="56dp" />

    <RadioGroup
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/radioGroup"
        android:layout_marginBottom="67dp"
        android:layout_above="@+id/submitButton"
        android:layout_alignLeft="@+id/radioButtons"
        android:layout_alignStart="@+id/radioButtons">

        <RadioButton
            android:layout_width="wrap_content"

            android:id="@+id/fivePercent"

            android:checked="false"
            android:textColor="@color/white"
            android:buttonTint="@color/white" />

        <RadioButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@id/somewhat"
            android:text="Somewhat"
            android:textSize="25dp"
            android:layout_below="@+id/fivePercent"
            android:layout_marginTop="35dp"
            android:textColor="@color/white"
            android:buttonTint="@color/white"/>

        <RadioButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/tenPercent"

            android:buttonTint="@color/white"/>

    </RadioGroup>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Are"
        android:textSize="33dp"
        android:textColor="@color/white"
        android:gravity="center"
        android:id="@+id/question"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="84dp"
        android:fontFamily="sans-serif-light" />

</RelativeLayout>

On the other note, you can only use

android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"

that you used for <View> WITHIN RelativeLayout
