问题 I'm trying to create a grid layout containing buttons but by default there is a space between these buttons and I don't need that. The .xml file looks like this: <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center"> <HorizontalScrollView android:id="@+id/HorizontalScrollView" android:layout_width="wrap_content" android:layout_height=

问题 I am trying to use a loop to set the action for each button when clicked (since most of the buttons will just return their text value), however I am getting an error stating "variable 'i' is accessed from within inner class, needs to be declared final".
