android – 如何将listview行中textview的值放入片段

概述在 Android应用程序上运行’我想从我的textview中传递值,该值位于listview的行中并将其放入片段中.我听说有关convertView.gettag和settag方法的说法,我不知道如何处理. 我的代码： public class EvaluationsFragment extends CustomFragment implements View.OnClickListener, 在 Android应用程序上运行’我想从我的textvIEw中传递值,该值位于ListvIEw的行中并将其放入片段中.我听说有关convertVIEw.gettag和settag方法的说法,我不知道如何处理.

解决方法 你做得很好,你需要一个捆绑来做到这一点.

首先创建一个String,您可以在其中保留值

holder.item_evaluation_nom.getText();

然后例如你这样做：

String itemEvaluation = holder.item_evaluation_nom.getText();

这是正确的捆绑包

EvaluationDetailHistoriqueFragment detail = new EvaluationDetailHistoriqueFragment();Bundle bundle = new Bundle();bundle.putString("text",itemEvaluation);detail.setArguments(bundle);

然后要检索这个,你这样做：

Bundle bundle = this.getArguments();if (bundle != null) {   String itemEvaluation = bundle.getString("text","");}

希望能帮助到你.

编辑

您需要将一个适配器添加到evaluateations_historic_Liste列表中.

你可以这样做：

evaluations_historic_Liste.setAdapter(new EvaluationAdapter(getActivity(),mEvaluation));

mEvaluation是您必须在其上放置数据的List.

然后在ListVIEw中添加：

evaluation_historic_Liste.setonItemClickListener(new OnItemClickListener() {public voID onItemClick(AdapterVIEw<?> adapter,VIEw v,long ID){   String itemEvaluation = (String) ((TextVIEw)vIEw.findVIEwByID(R.ID.item_evaluation_nom)).getText();  //or String itemEvaluation=(evaluation_historic_Liste.getItemAtposition(position).toString()); }}
