in android manifest declare activity named basketball_tutorial_home_page here:
<activity android:name=".basketball_tutorial_home_page" android:label="basketball tutorials" android:parentactivityname=".mainactivity"> </activity> while didn't specify name of basketball tutorial's activity class is, i'm going assume followed standards , activity class name uppercamelcase (something basketballtutorial), whereas layout xml file snake_case (something basketball_tutorial_home_page.xml).
if case, problem not using right name in manifest. android:name attribute needs refer java class, not layout xml file. attribute should more android:name=".basketballtutorial".
additionally, looks have odd attributes in basketball tutorial xml, may causing error seeing in logcat.
- you using
android:theme="@style/textappearance.appcompat.body2", overriding entire theme buttons. want override text appearance usingandroid:textappearance="@style/textappearance.appcompat.body2". overriding whole theme result in odd attributes android:inputtypeisn't needed buttons- since can't input text button, setting input type won't anything.- when using
android:layout_weight, should set eitherandroid:layout_heightorandroid:layout_width0dpspecify whether want width or height stretch.
