之前介绍了xUtils3.0的导入和权限配置，现在再来逐一介绍xUtils3的4大模块：注解模块，网络模块，图片加载模块，数据库模块。
注解模块
xml布局注解： 1，Activity中的xml布局加载：
@ContentView(R.layout.activity_main)//加载的xml文件
public class ActivityTest extends Activity {@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
x.view().inject(this);
//注解绑定
}
}2， Fragment中的xml布局加载：
@ContentView(R.layout.activity_main)//加载的xml文件
public class FragmentTest extends Fragment {@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return x.view().inject(this, inflater, container);
//绑定fragment注解
}
}3，ViewHolder的注解加载：
public class AdapterTest extends BaseAdapter {
private Context context;
private Holder holder;
public ActivityTest(Context context){
this.context = context;
}...@Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null){
convertView=View.inflate(context,R.layout.item, null);
holder=new Holder();
x.view().inject(holder,convertView);
//注解绑定
convertView.setTag(holder);
}
else{
holder=(Holder) convertView.getTag();
}return convertView;
}
private class Holder{
@ViewInject(R.id.item_name)private TextView tv_name;
//id声明
@ViewInject(R.id.item_image)private ImageView iv_image;
}}【xUtils3.0使用介绍（注解模块）】以上几种的布局文件的绑定都是大同小异，来来去去都是x.view().inject(）的用法
响应事件注解：
/**
*等同于@Event(value=https://www.it610.com/article/{R.id.id_but1,R.id.id_but2},type=View.OnClickListener.class)
*/
@Event(value={R.id.id_but1,R.id.id_but2}) //type默认为OnClickListener
private void getEvent(View view){//必须用private进行修饰,否则无效
switch(view.getId()){
case R.id.id_but1:
break;
case R.id.id_but2:
break;
}
}
