xUtils之view注入--Android

關于xUtils的使用有各種各樣的說明和文章，今天主要結合自己的項目總結一下view注入的方面。

添加xUtils庫後

@ViewInject(R.id.textView)

TextView textView;

//@ViewInject(vale=R.id.textView, parentId=R.id.parentView)

//TextView textView;

1.在Activity中注入：

@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    ViewUtils.inject(this); //注入view和事件

    ...

    textView.setText("some text...");

    ...

}

2.在Fragment中注入：

@Override

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

    View view = inflater.inflate(R.layout.bitmap_fragment, container, false); // 加載fragment布局

    ViewUtils.inject(this, view); //注入view和事件

    ...

}

3.在PreferenceFragment中注入：

public void onActivityCreated(Bundle savedInstanceState) {

    super.onActivityCreated(savedInstanceState);

    ViewUtils.inject(this, getPreferenceScreen()); //注入view和事件

    ...

}

4.在Adapter中注入

public class MxnGridViewAdapter extends BaseAdapter {

class ViewHolder {

@ViewInject(R.id.home_grid_image)

public ImageView image;

@ViewInject(R.id.home_grid_text)

public TextView title;

}

       ...

       @Override

public View getView(int position, View convertView, ViewGroup parent) {

ViewHolder viewHolder;

if (convertView == null) {

convertView = inflater.inflate(R.layout.fhome_grid_item, null);

viewHolder = new ViewHolder();

ViewUtils.inject(viewHolder,convertView);

convertView.setTag(viewHolder);

} else {

viewHolder = (ViewHolder) convertView.getTag();

}

viewHolder.title.setText(titles[position]);

viewHolder.image.setImageResource(images[position]);

return convertView;

}
