Invalid layout param

Question

I'm getting the following errors and can't work out what the problem is.

• Invalid layout param in a relativelayout: layout_centerHorizontal
• Invalid layout param in a relativelayout: layout_alignParentTop

The code that has these errors is:

<textview android:id="@+id/textView"
          android:layout_alignParentTop="true"
          android:layout_centerHorizontal="true"
          android:layout_gravity="center"
          android:layout_height="wrap_content"
          android:layout_width="wrap_content"
          android:text="@string/welcome"
          android:textColor="#000000">

Thanks.

EDIT: The whole layout file code-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:android1="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:orientation="vertical" >

Answer 1

This XML is not even well-formed, lots of elements have a starting tag, and no end tag. For example, instead of <TextView> you should write <TextView></TextView>, or, better, <TextView/>. Fix that, and check the errors again.

Answer 2

1. you have no closing tag for Relative Layout (add </RelativeLayout> at the end)
2. Your Views are in a complete mess, try to clean format your code and you will see following:

``

 <TextView ...>
        <EditText ...>
            <Button ...>
            </Button>
            <Button ...>
                <TextView ....>
                     <TextView ...>
                           <EditText ...>
                                 <TextView ...>
                                 </TextView>
                           </EditText>
                     </TextView>
                </TextView>
            </Button>
            <Button ...>

You are trying to warp textviews inside edittexts and buttons and so forth... that wont work. try following:

<TextView ... />
<EditText ... />
