变魔术的RoboGuice

site: http://code.google.com/p/roboguice/

RoboGuice is a framework that brings the simplicity and ease of Dependency Injection to Android, using Google's own Guice library.

打个比方，RoboGuice就是苦力的干活，它的能力就是帮你代劳编程中的各种琐事，比如：

使用前：
clas AndroidWay extends Activity {
TextView name;
ImageView thumbnail;
LocationManager loc;
Drawable icon;
String myName;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
name = (TextView) findViewById(R.id.name);
thumbnail = (ImageView) findViewById(R.id.thumbnail);
loc = (LocationManager) getSystemService(Activity.LOCATION_SERVICE);
icon = getResources().getDrawable(R.drawable.icon);
myName = getString(R.string.app_name);
name.setText( "Hello, " + myName );
}
}

使用后：
class RoboWay extends RoboActivity {
@InjectView(R.id.name) TextView name;
@InjectView(R.id.thumbnail) ImageView thumbnail;
@InjectResource(R.drawable.icon) Drawable icon;
@InjectResource(R.string.app_name) String myName;
@Inject LocationManager loc;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
name.setText( "Hello, " + myName );
}
}
