使用 for activity:
ViewHelperhelper=newViewHelper(MainActivity.this);helper.id(R.id.text_view).text("helloworld");helper.id(R.id.button).clicked(newView.OnClickListener(){@OverridepublicvoidonClick(Viewv){}});helper.id(R.id.image_view).image("http://www.xxxxx.com/xxx.png"); 使用 for view:
Viewview=LayoutInflater.from(getContext()).inflate(R.layout.view,null);ViewHelperhelper=newViewHelper(view);helper.id(R.id.text_view).text("helloworld");helper.id(R.id.button).clicked(newView.OnClickListener(){@OverridepublicvoidonClick(Viewv){}});helper.id(R.id.image_view).image("http://www.xxxxx.com/xxx.png"); ViewHelper.java 源码
publicclassViewHelper{privateViewroot;privateViewview;privateActivityact;publicViewHelper(Viewview){this.root=view;this.view=view;}publicViewHelper(Activityactivity){this.act=activity;}publicViewHelperid(intid){this.view=findView(id);returnthis;}privateViewfindView(intid){Viewresult=null;if(root!=null){result=root.findViewById(id);}elseif(act!=null){result=act.findViewById(id);}returnresult;}publicViewHelpertext(CharSequencetext){if(viewinstanceofTextView){TextViewtv=(TextView)view;tv.setText(text);}returnthis;}publicViewHelperclicked(View.OnClickListenerlistener){if(view!=null){view.setOnClickListener(listener);}returnthis;}publicViewHelperimage(Stringuri){returnimage(uri,null);}publicViewHelperimage(Stringuri,DisplayImageOptionsoptions){if(viewinstanceofImageView){ImageViewiv=(ImageView)view;ImageLoaderimageLoader=ImageLoader.getInstance();imageLoader.displayImage(uri,iv,options);}returnthis;}} 更多相关文章
