Android依赖注入:Google Guice on Android的使用及相关资源
本文转自:http://blog.csdn.net/sangming/article/details/8878104
RoboGuice 使用谷歌自己的Guice库,给Android带来了简单和易用的依赖注入。如果你使用过Spring或Guice的话,你可能已经知道这种编程方式是多么的便捷。
RoboGuice 允许使用annotation 的方式来描述id于View之间的关系,其余的工作由roboGuice库来完成。比如:
- class 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 );
- }
- }
如果使用roboguice 来写:
- 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 );
- }
- }
注意:activity必须继承自RoboActivity
