Set style on TableRow in Android

阅读更多关于 Set style on TableRow in Android

问题 Using the Android SDK, there doesn't seem to be any way to set the style on a table row. I want to do the equivalent of: <TableRow style='@style/TableRow_classic' > in code. I would like something like: TableRow row = new TableRow(this); row.setStyle(R.style.TableRow_classic); Does anyone know how to find this? 回答1: The best solution I've found to accomplish this is to create a "partial" layout representing the table row, with a style defined: <?xml version="1.0" encoding="utf-8"?> <TableRow

Android Layout - when to use app: vs android:?

阅读更多关于 Android Layout - when to use app: vs android:?

I've been writing some Android apps but I don't really understand when to use app: and when to use android: .

It'd be great if someone could point me in the right direction. Thanks! You are talking about custom namespace.In android we can create custom views in additional to already available views. As per in Google developer docs.. To add a built-in View to your user interface, you specify it in an XML element
