wie Wert im Bearbeiten von Text aus erweiterbaren recycelbar

Question

zu bekommen, wie Wert im Bearbeiten von Text aus erweiterbar recycelbar in Android zu bekommen, und ich verwenden, um diesen "com.thoughtbot: expandablerecyclerview: 1.0" Bibliothek in Android Studio. Kann nicht korrekten Wert erweiterbar recycelbar

public class MasterAdapter extends ExpandableRecyclerViewAdapter<ParentView, ChildView> { 

    private List<? extends ExpandableGroup> list; 
    private Activity activity; 
    private Button button; 

    public MasterAdapter(Activity activity, List<? extends ExpandableGroup> list) { 
     super(list); 
     this.activity = activity; 
     this.list = list; 
     button = (Button) activity.findViewById(R.id.btnOk); 
    } 

    @Override 
    public ParentView onCreateGroupViewHolder(ViewGroup parent, int viewType) { 

     View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.parent_view, parent, false); 
     ParentView parentView = new ParentView(view); 
     return parentView; 
    } 

    @Override 
    public ChildView onCreateChildViewHolder(ViewGroup parent, int viewType) { 
     View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.child_view, parent, false); 
     ChildView childView = new ChildView(view); 
     return childView; 
    } 

    @Override 
    public void onBindChildViewHolder(final ChildView holder, int flatPosition, ExpandableGroup group, int childIndex) { 
     DataValue dataValue = ((MainData) group).getItems().get(childIndex); 
     holder.Bind(dataValue); 
// 
     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
//    String editTextData = ((EditText) view).getText().toString().trim(); 
       String editTextData = holder.editText.getText().toString().trim(); 

       if (holder.editText!=null) { 
//     Toast.makeText(activity, editTextData, Toast.LENGTH_LONG).show(); 
        Toast.makeText(activity, editTextData, Toast.LENGTH_LONG).show(); 
       } 
      } 
     }); 
    } 

    @Override 
    public void onBindGroupViewHolder(ParentView holder, int flatPosition, ExpandableGroup group) { 
     holder.getTitle(group); 
    } 
} 

ParentView.class

public class ParentView extends GroupViewHolder { 

    TextView textView; 

    public ParentView(View view) { 
     super(view); 
     textView = (TextView) view.findViewById(R.id.parentName); 
    } 

    public void getTitle(final ExpandableGroup group) { 
     textView.setText(group.getTitle()); 
    } 
} 

ChildView.class

public class ChildView extends ChildViewHolder { 

    EditText editText; 
    String string; 

    public ChildView(View view) { 
     super(view); 
     editText = (EditText) view.findViewById(R.id.childtName); 

    } 
    public void Bind(DataValue dataValue) { 
     editText.setText(dataValue.getName()); 

    } 

} 

DataValue.class

erhalten

public class DataValue implements Parcelable { 

    private String title; 
    private String name; 

    public DataValue(String title, String name) { 
     this.title = title; 
     this.name = name; 
    } 

    public DataValue(String name) { 
     this.name = name; 
    } 

    public String getTitle() { 
     return title; 
    } 

    public void setTitle(String title) { 
     this.title = title; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    @Override 
    public int describeContents() { 
     return 0; 
    } 

    @Override 
    public void writeToParcel(Parcel parcel, int i) { 

    } 

MAINDATA

public class MainData extends ExpandableGroup<DataValue> { 

    public MainData(String title, List<DataValue> items) { 
     super(title, items); 
    } 
} 

Answer 1

Ich glaube, Sie Schnittstelle, wenn der Benutzer Klick auf den Button zu handhaben können und Eingabetext erhalten.

Schritt 1: Definieren Schnittstelle

public interface GetInputListener{ 

public void getInput(String message); 

} 

Schritt 2: Verwenden Sie Schnittstelle auf der Adapterklasse:

public class MasterAdapter extends ExpandableRecyclerViewAdapter<ParentView, ChildView> { 

    private List<? extends ExpandableGroup> list; 
    private Activity activity; 
    private Button button; 
    private GetInputListener getInputListener; 

    public MasterAdapter(Activity activity, List<? extends ExpandableGroup> list, GetInputListener listener) { 
     super(list); 
     this.activity = activity; 
     this.list = list; 
     button = (Button) activity.findViewById(R.id.btnOk); 
     this.getInputListener = listener; 
    } 

    @Override 
    public ParentView onCreateGroupViewHolder(ViewGroup parent, int viewType) { 

     View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.parent_view, parent, false); 
     ParentView parentView = new ParentView(view); 
     return parentView; 
    } 

    @Override 
    public ChildView onCreateChildViewHolder(ViewGroup parent, int viewType) { 
     View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.child_view, parent, false); 
     ChildView childView = new ChildView(view); 
     return childView; 
    } 

    @Override 
    public void onBindChildViewHolder(final ChildView holder, int flatPosition, ExpandableGroup group, int childIndex) { 
     DataValue dataValue = ((MainData) group).getItems().get(childIndex); 
     holder.Bind(dataValue); 

     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       //String editTextData = ((EditText) view).getText().toString().trim(); 
       String editTextData = holder.editText.getText().toString().trim(); 

       if (holder.editText!=null) { 
        listener.getInput(editTextData); 
       } 
      } 
     }); 
    } 

    @Override 
    public void onBindGroupViewHolder(ParentView holder, int flatPosition, ExpandableGroup group) { 
     holder.getTitle(group); 
    } 
} 

Schritt 3: Verwenden Sie Adapter und Eingang Hörer für diesen Adapter. In der Callback-Methode getInput() können Sie eine Eingabe von editiertext erhalten.

@Override 
public void getInput(String message){ 

} 

Ich denke, es wird Ihnen helfen.
