Android RoboGuice使用指南(18) Inject Resources

Roboguice 對訪問res 目錄下各種資源drawable, arrary, string 等也提供 了注入支援。可以通過@InjectResource 很方便的應用所需資源。

本例修 改Android ApiDemos樣本解析(48)：Content->Resources->Resources 使 用Inject Resource方法來訪問資源。

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);                }               }
