I am getting layout inflater error while using android:textSize="?android:attr/textAppearanceLarge" in my xml -

my application crashing if using android:textsize="?android:attr/textappearancelarge" in xml . don't want give hard coded text size because have create create xml different screen sizes or have manage text size @ run time.

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical" >     <edittext         android:id="@+id/title"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:hint="@string/title"         android:textsize="?android:attr/textappearancelarge" />     <linearlayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="horizontal" >         <button             android:id="@+id/saveondialog"             android:layout_width="0dp"             android:layout_height="wrap_content"             android:layout_weight="0.5"             android:text="@string/save"             style="?android:attr/buttonbarbuttonstyle"             android:textsize="?android:attr/textappearancelarge" />         <button             android:id="@+id/cancelondialog"             android:layout_width="0dp"             android:layout_height="wrap_content"             android:layout_weight="0.5"             android:text="@string/cancel"             style="?android:attr/buttonbarbuttonstyle"             android:textsize="?android:attr/textappearancelarge" />     </linearlayout> </linearlayout>

use android:textappearance="?android:attr/textappearancemedium"

instead of

android:textsize="?android:attr/textappearancemedium"
