} I don't know about this error. Is there any property i am missing in xml? I am new to android development Thanks in advance.

Answer 1

I observed that if i saperate the class then its working fine. But if its inner class its not working and giving me that error. Why its happening like that I don't know. does anyone know how can I do it with inner class?

Answer 2

I got the solution here - enter link description here

I put it in class property-

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight=".35" 
        class = "com.xyz.FeatureTop">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@android:color/white"
            android:gravity="center"
            android:text="Hello Feature Top"
            android:textColor="@android:color/black" />
    </LinearLayout>

Answer 3

Instead of

<com.xyz.Middle
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight=".35" >
{...}
</com.xyz.Middle>

try this (this is the syntax for inner classes) if your Xyz class in in package com.xyz:

<com.xyz.Xyz$Middle
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight=".35" >
{...}
</com.xyz.Middle>

And do the same for com.xyz.FeatureBottom and etc.
