android xml tag strings combine

how to connect two strings?

<TextView android:text="@string/app_name.@string/app_version" android:layout_height="wrap_content" android:layout_width="fill_parent"开发者_C百科 android:gravity="center" android:layout_alignParentLeft="true" android:id="@+id/Welcome" android:textSize="34px"></TextView>

android:text="@string/app_name.@string/app_version"

the emulator directly printed "@string/app_name.@string/app_version" instead of the string it supposed to be something like "APP 1.2"

you can't do that, if you want to use two strings in your TextView, you'd have to set the text programmatically:

TextView tv = (TextView)findViewById(R.id.welcome);
tv.setText(getString(R.string.app_name) + getString(R.string.app_version));
