Android butterknife注解框架

欢迎大家访问我的博客http://blog.csdn.net/mikejaps，专注于android ios app 开发

首先提下ButterKnifey已经更新到版本7.0.1了，现在注解已经不叫@InjectView了，而叫@Bind，感觉更贴合语义。同时注册的方式也从

ButterKnife.inject(this);

变成了

ButterKnife.bind(this);

关于7.0.1的ButterKnife的各种用法和功能，可以参考ButterKnife的github上的主页：

//activity中使用

public class MainActivity extends Activity {

@InjectView(R.id.tv_test)
TextView tvTest;
@OnClick(R.id.submit)
public void sayHi(Button button) {
button.setText("Hello!");
}																   																   @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.inject(this);
tvTest.setText("test");
}

@OnClick(R.id.tv_test)
public void sayHi() {
tvTest.setText("Hello!");
}
}

// fragment中使用

public class FancyFragment extends Fragment {

@InjectView(R.id.button1) Button button1;

@InjectView(R.id.button2) Button button2;

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

View view = inflater.inflate(R.layout.fancy_fragment, container, false);

ButterKnife.inject(this, view);

// TODO Use "injected" views...

return view;

}

@Override void onDestroyView() {

super.onDestroyView();

ButterKnife.reset(this);

}

}

//adpter中使用

public class MyAdapter extends BaseAdapter {

@Override public View getView(int position, View view, ViewGroup parent) {

ViewHolder holder;

if (view != null) {

holder = (ViewHolder) view.getTag();

} else {

view = inflater.inflate(R.layout.whatever, parent, false);

holder = new ViewHolder(view);

view.setTag(holder);

}

holder.name.setText("John Doe");

// etc..
return convertView;

}

static class ViewHolder {

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

@InjectView(R.id.job_title) TextView jobTitle;

public ViewHolder(View view) {

ButterKnife.inject(this, view);

}

}

}
