Android RoboGuice 使用指南(18):Inject Resources

Roboguice 对访问res 目录下各种资源drawable, arrary, string 等也提供了注入支持。可以通过@InjectResource 很方便的应用所需资源。

本例修改Android ApiDemos示例解析(48)：Content->Resources->Resources 使用Inject Resource方法来访问资源。

public class InjectResourceDemo extends RoboActivity {
 
 @InjectView (R.id.styled_text) TextView styled_text;
 @InjectView (R.id.plain_text) TextView plain_text;
 @InjectView (R.id.res1) TextView res1;
 @Inject Resources res;
 @InjectResource(R.string.styled_text) String str;
 
 @Override
 public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.injectresource);
 
 //Use res to get the string resources
 CharSequence cs=res.getText(R.string.styled_text);
 // Note the use of
 // CharSequence instead of String
 // so we don't lose the style info.
 styled_text.setText(cs);
 
 // Use the same resource, but convert it to
 // a string, which causes it
 // to lose the style information.
 plain_text.setText(str);
 res1.setText(cs);
 
 }
 
}
