超级简单的ButterKnife使用技巧

简单明了，步骤如下：

1、框架的导入

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">eclipse：官网下载jar包，复制到lib文件夹</span>

Android Studio： File->Project Structure->Dependencies->Library dependency 搜索butterknife即可

2、使用情景

①、Activity和View的绑定

class BaseActivity extends Activity {
  @BindView(R.id.title) TextView title;
  @BindView(R.id.subtitle) TextView subtitle;
  @BindView(R.id.footer) TextView footer;

  @Override public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple_activity);
    ButterKnife.bind(this);
    // TODO Use fields...
  }

  @Overrid public void onDestory(){

<span style="white-space:pre">	</span>super.onDestory();

<span style="white-space:pre">	</span>ButterKnife.unBind(this);<span style="white-space:pre">	</span>
   }

 }

②Fragment的绑定

public abstract class BaseFragment extends Fragment {
    protected View mRootView;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        mRootView =inflater.inflate(getContentViewId(),container,false);
        ButterKnife.bind(this,mRootView);//绑定framgent
                return mRootView;
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        ButterKnife.unbind(this);//解绑
    }
}

③Adapter中的绑定

public class TestAdapter extends BaseAdapter {
    private List<String> list;
    private Context context;


    public TestAdapter(Context context, List<String> list) {
        this.list = list;
        this.context = context;
    }


    @Override
    public int getCount() {
        return list==null ? 0 : list.size();
    }


    @Override
    public Object getItem(int position) {
        return list.get(position);
    }


    @Override
    public long getItemId(int position) {
        return position;
    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.layout_list_item, null);
            holder = new ViewHolder(convertView);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.textview.setText("item=====" + position);
        return convertView;
    }


    static class ViewHolder {
        @Bind(R.id.hello_world)
        TextView textview;


        public ViewHolder(View view) {
            ButterKnife.bind(this, view);
        }
    }
}

④点击事件绑定

参数的指定可选

@OnClick(R.id.submit)
public void submit(View view) {
  // TODO submit data to server...
}

<pre name="code" class="java" style="font-size: 18px; line-height: 26px;">@OnClick(R.id.submit)
public void submit() {
  // TODO submit data to server...
}

定义一个特定类型，它将自动转换

@OnClick(R.id.submit)
public void sayHi(Button button) {
  button.setText("Hello!");
}

多个view绑定一个onClick事件

@OnClick({ R.id.view1, R.id.view2, R.id.view3 })
    public void click(View view) {
<span style="white-space:pre">	</span>
}

总的来说常用的功能如上，由于之前用过Xutils3.0做注解，感觉和ButterKnife差不多，具体区别以后再体会。希望有大神看到本篇博文可以评论指教一番
