Android activity Binary XML file line : You must supply a layout_width attribute

Question

I've read about it already, but still it's here.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
tools:context=".TaskEditActivity" >

So, the exception java.lang.RuntimeException: Binary XML file line #34: You must supply a layout_width attribute.

Attribute is there, schema too... Solution?

Answer 1

Also i recommend check your dimens. You may have layout width in dimens, you go to it and you have value like "150" not "150dp" (missing dp) also cause this (that was my case)

Answer 2

I had a dimension for a given width but it wasn't present in the default dimens.xml

res/    values-w320dp/           dimens.xml -> ring_radius=5dp    values/           dimens.xml -> missing ring_radius 

Answer 3

It's clear. Child elements missed layout_width attribute.
