在android应用程序上工作时，我想从我的textview中传递一个值，这个值在listview的一行中，并将它放在一个片段中。我听说convertview.gettag和settag方法put我不知道该怎么处理。
我的代码：
public class EvaluationsFragment extends CustomFragment implements View.OnClickListener, AdapterView.OnItemSelectedListener {
private Patient mPatient;
private View myView;
private Context context;
private Button btnAjoutEvaluation;
private ListView evaluations_historic_liste;
private List<Evaluation>mEvaluation;
private EvaluationDto mEvaluationDto;
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState){
myView = inflater.inflate(R.layout.fragment_evaluations, container,false);
return myView;
}
@Override
public void onActivityCreated(Bundle savedInstanceState){
super.onActivityCreated(savedInstanceState);
init();
}
private void init(){
evaluations_historic_liste = (ListView)myView.findViewById(R.id.evaluations_historic_liste);
btnAjoutEvaluation = (Button)myView.findViewById(R.id.evaluations_add__btn);
btnAjoutEvaluation.setOnClickListener(this);
TypeEvaluation mNouveauTypeEvaluation;
mPatient =((DossierActivity)mRootActivity).mPatient;
mEvaluationDto = new EvaluationDto(mRootActivity.getApplicationContext());
evaluations_historic_liste.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
EvaluationAdapter.EvaluationItem item = (EvaluationAdapter.EvaluationItem)view.getTag();
openDetailEvaluation(item);
}
});
mEvaluationDto.open();
try{
mEvaluation = mEvaluationDto.getEvaluationsByPatientId(mPatient.getId());
}catch (SQLException e) {
Log.e(Constants.APP_LOG_TAG, e.getMessage());
ACRA.getErrorReporter().handleException(e);
} finally{
mEvaluationDto.close();
}
if(mEvaluation != null && mEvaluation.size() >0){
evaluations_historic_liste.setAdapter(new EvaluationAdapter(mRootActivity,mEvaluation));
}else {
evaluations_historic_liste.setVisibility(View.GONE);
}
}
@Override
public void onClick(View v) {
switch(v.getId()){
case (R.id.evaluations_add__btn):
openNewEvaluation();
break;
}
}
public void openNewEvaluation(){
Fragment fragment = new EvaluationNouvelleFragment();
android.support.v4.app.FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.content_frame, new EvaluationNouvelleFragment());
fragmentTransaction.commit();
}
public void openDetailEvaluation(EvaluationAdapter.EvaluationItem item){
EvaluationAdapter evaluationAdapter = new EvaluationAdapter();
EvaluationDetailHistoriqueFragment detail = new EvaluationDetailHistoriqueFragment();
Bundle args = new Bundle();
args.putString(EvaluationDetailHistoriqueFragment.DATA_RECEIVE, /*HERE I NEED TO PUT item_evaluation_nom.setText()*/ );

最佳答案
你做得很好，你需要一个Bundle来做这个。
首先创建一个String，在这里您可以保留holder.item_evaluation_nom.getText();
例如，您可以这样做：
String itemEvaluation = holder.item_evaluation_nom.getText();
这是正确的
BundleEvaluationDetailHistoriqueFragment detail = new EvaluationDetailHistoriqueFragment();
Bundle bundle = new Bundle();
bundle.putString("text", itemEvaluation);
detail.setArguments(bundle);
然后要检索此文件，请执行以下操作：
Bundle bundle = this.getArguments();
if (bundle != null) {
String itemEvaluation = bundle.getString("text", "");
}
希望有帮助。

您需要在
Adapter列表中添加一个evaluations_historic_liste。你可以这样做：
evaluations_historic_liste.setAdapter（新的evaluationAdapter（getActivity（），meValuation））；
mEvaluation是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, int position, long id){
String itemEvaluation = (String) ((TextView)view.findViewById(R.id.item_evaluation_nom)).getText();
//or
String itemEvaluation=(evaluation_historic_liste.getItemAtPosition(position).toString());
}
}
