帶有EditText和SwipeDismissListViewTouchListener的ListView

Question

我創建了一個ListView，每行都有一個EditText。 ListView還允許用戶使用https://github.com/romannurik/Android-SwipeToDismiss中的SwipeDismissListViewTouchListener.java通過水平滑動來刪除列表中的項目。

這兩種功能都能正常工作，除非用戶試圖通過EditText上發生的初始ACTION_DOWN事件執行滑動手勢。看起來EditText在傳遞給SwipeDismissListViewTouchListener之前正在使用ACTION_DOWN事件，該事件需要ACTION_DOWN事件來初始化手勢。

問：

我怎樣才能獲得SwipeDismissListViewTouchListener當輕掃手勢上的EditText開始工作？

SampleListFragment.java：

import android.app.Activity; 
import android.app.ListFragment; 
import android.content.Context; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup;

import java.util.ArrayList; 

public class SampleListFragment extends ListFragment { 

    protected AddGroupAdapter adapter; 
    protected ListView lv; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     adapter = new AddGroupAdapter(getActivity()); 
     setListAdapter(adapter); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.fragment_sample, container, false); 
     return view; 
    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     lv = getListView(); 
     SwipeDismissListViewTouchListener listener = 
       new SwipeDismissListViewTouchListener(
         lv, 
         new SwipeDismissListViewTouchListener.DismissCallbacks() { 
          @Override 
          public boolean canDismiss(int position) { 
           return true; 
          } 

          @Override 
          public void onDismiss(ListView listView, int[] reverseSortedPositions) { 
           for (int position : reverseSortedPositions) { 
            adapter.removeRecord(position);

           adapter.notifyDataSetChanged(); 
          } 
         }); 
     lv.setOnTouchListener(listener); 
     lv.setOnScrollListener(listener.makeScrollListener()); 

     super.onActivityCreated(savedInstanceState); 
    }

      for (int i = 0; i < 10; i++) { 
       data.add("Sample Text " + String.valueOf(i)); 
      } 
      notifyDataSetChanged(); 
     }

      data.remove(position);

     @Override

      ViewHolder holder; 
      if (convertView == null) { 
       holder = new ViewHolder(); 
       convertView = mInflater.inflate(R.layout.row, null); 
       holder.edit = (EditText) convertView.findViewById(R.id.edit_text); 
       convertView.setTag(holder); 
      } else { 
       holder = (ViewHolder) convertView.getTag(); 
      } 

      holder.edit.setText(data.get(position)); 
      holder.edit.setId(position); 
      holder.edit.setOnFocusChangeListener(new View.OnFocusChangeListener() { 
       @Override 
       public void onFocusChange(View view, boolean hasFocus) { 
        if (!hasFocus) { 
         final int position = view.getId(); 
         final EditText edit = (EditText) view; 
         if (edit.getText() != null && !edit.getText().toString().isEmpty()) 
          if (position < getCount()) 
           data.set(position, edit.getText().toString()); 
        } 
       } 
      }); 

      return convertView;

    static class ViewHolder { 
     EditText edit;

</LinearLayout> 

Answer 1

嘗試添加以下內容到LinearLayout我n個row.xml：

android:descendantFocusability="blocksDescendants"

因此很明顯，一個EditText是棘手比按鈕有一個列表視圖中。也許這個答案可以讓你在正確的方向，如果你必須有你的：https://stackoverflow.com/a/2680077/362298
