Android using Linear layout maxWidth, not work with fill_parent

Question

When using fill_parent, maxWidth has no effect.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"               android:layout_width="fill_parent"               android:layout_height="match_parent"               android:orientation="vertical">     <LinearLayout android:layout_width="fill_parent"                   android:layout_height="match_parent"                   android:orientation="vertical">         <EditText android:layout_width="match_parent"                   android:layout_height="wrap_content"                   android:maxWidth="50dip"/>     </LinearLayout>     </LinearLayout> 

Answer 1

The attribute maxWidth has no effect on a width of match_parent (or the deprecated fill_parent), they are mutually exclusive. You need to use wrap_content.

Also any layout that only has one child can probably be removed, for instance you can simplify you current layout to:

<?xml version="1.0" encoding="utf-8"?> <EditText xmlns:android="http://schemas.android.com/apk/res/android"           android:layout_width="wrap_content"           android:layout_height="wrap_content"           android:maxWidth="50dip"/>
