xamarin.android - How can I resolve "No resource identifier found" for attributes in my Android project? -
i'm trying implement simple gridlayout in xamarin studio, outlined in example:
<gridlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:columncount="4" android:orientation="horizontal" > <button android:layout_column="3" android:text="/" /> <button android:text="1" /> <button android:text="2" /> <button android:text="3" /> <button android:text="*" /> <button android:text="4" /> <button android:text="5" /> <button android:text="6" /> <button android:text="-" /> <button android:text="7" /> <button android:text="8" /> <button android:text="9" /> <button android:layout_gravity="fill" android:layout_rowspan="3" android:text="+" /> <button android:layout_columnspan="2" android:layout_gravity="fill" android:text="0" /> <button android:text="00" /> <button android:layout_columnspan="3" android:layout_gravity="fill" android:text="=" /> </gridlayout> but won't build. i'm getting following errors:
error: no resource identifier found attribute 'columncount' in package 'android' (androidapplication1) error: no resource identifier found attribute 'layout_rowspan' in package 'android' (androidapplication1) error: no resource identifier found attribute 'layout_columnspan' in package 'android' (androidapplication1) error: no resource identifier found attribute 'layout_columnspan' in package 'android' (androidapplication1)
what need change make work?
try add explicitly dependency support:gridlayout-v7, have dependency support:preference-v7.
if using gradle, should looks in build.gradle (module app) : compile 'com.android.support:gridlayout-v7:23.0.+'
