使用方法：

1. @InjectView

---

@InjectView可以简化组件的查找注册，包括android自带的组件和自定义组件。在使用@InjectView之前，我们会这样写代码

          public class MainActivity extends Activity {

                ImageView imageView;

                @Override
                protected void onCreate(Bundle savedInstanceState) {
                  super.onCreate(savedInstanceState);

                  setContentView(R.layout.activity_main);
                  imageView = (ImageView) findViewById(R.id.imageview);
                }
           }

在使用@InjectView之后，会这样写代码

          public class MainActivity extends Activity {

                @InjectView(R.id.imageView)
                ImageView imageView;

                @Override
                protected void onCreate(Bundle savedInstanceState) {
                   super.onCreate(savedInstanceState);

                   setContentView(R.layout.activity_main);
                   Injector.injectInto(this);
                }
          }

目前，@InjectView可用于Activity、Dialog、Fragment中。在Activity和Dialog用法相似，在Fragment中用法有一点区别。

          public class DemoFragment extends Fragment {

                   @InjectView(R.id.title)
                   TextView titleView;

                   @InjectView(R.id.imageview)
                   ImageView imageView;

                   @Override
                   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
                          View v = inflater.inflate(R.layout.fragment_demo, container, false);

                          Injector.injectInto(this,v); // 和Activity使用的区别之处在这里

                          initViews();
                          initData();

                          return v;
                   }

                  ......
           }

2. @InjectViews

---

          public class MainActivity extends Activity {

                @InjectViews(ids={R.id.imageView1,R.id.imageView2})
                ImageView[] imageviews;

                @Override
                protected void onCreate(Bundle savedInstanceState) {
                   super.onCreate(savedInstanceState);

                   setContentView(R.layout.activity_main);
                   Injector.injectInto(this);
                }
          }

3. @InjectExtra

---

         /**
          * MainActivity传递数据给SecondActivity
          * Intent i = new Intent(MainActivity.this,SecondActivity.class);                                               
          * i.putExtra("test", "saf");
          * i.putExtra("test_object", hello);
          * startActivity(i);
          * 在SecondActivity可以使用@InjectExtra注解
          *
          * @author Tony Shen
          *
          */
         public class SecondActivity extends Activity{

               @InjectExtra(key="test")
               String testStr;

               @InjectExtra(key="test_object")
               Hello hello;

               protected void onCreate(Bundle savedInstanceState) {
                   super.onCreate(savedInstanceState);

                   Injector.injectInto(this);
                   Log.i("++++++++++++","testStr="+testStr);
                   Log.i("++++++++++++","hello="+SAFUtil.printObject(hello)); // 该方法用于打印对象
              }
          }

4. @OnClick

---

@OnClick 可以在Activity、Fragment、Dialog、View中使用，也支持多个组件绑定同一个方法。

     public class AddCommentFragment extends BaseFragment {

         @Override
         public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

             View v = inflater.inflate(R.layout.fragment_add_comment, container, false);

             Injector.injectInto(this, v);

             initView();

             return v;
        }

	    @OnClick(id={R.id.left_menu,R.id.btn_comment_cancel})
	    void clickLeftMenu() {
		    popBackStack();
	    }

	    @OnClick(id=R.id.btn_comment_send)
	    void clickCommentSend() {
            if (StringHelper.isBlank(commentEdit.getText().toString())) {
               ToastUtil.showShort(mContext, R.string.the_comment_need_more_character);
            } else {
               AsyncTaskExecutor.executeAsyncTask(new AddCommentTask(showDialog(mContext)));
            }
	    }

	    ....
    }
