Question

我在列表视图中有一个编辑文本。 Listview是使用Base Adapter创建的，并使用Holders加载编辑文本。

当我cal holder.edtText.hasFocus（）时，它总是返回false。我在ListView属性中缺少的任何东西？

public View getView(final int position, View convertView, final   
    ViewGroup parent) 
    {                                 
    if (convertView == null) 
    {                     
    LayoutInflater inflater = LayoutInflater.from(getContext());                          

    convertView = inflater.inflate(R.layout.screen, parent, false);                       
    holder = new Adapter.ViewHolder(convertView);                     
    convertView.setTag(holder);                 
    }
    else 
    {                     
    holder = (Adapter.ViewHolder) convertView.getTag();           
    }                                                   
    holder.edt.setCursorVisible(holder.edt.hasFocus());                 
    holder.edt.setEnabled(true);                                  
    holder.edt.setTag(R.string.view, “some object”);
                 
    if (position == 10) 
    {                     
    holder.edt.requestFocus();                 
    }
             holder.edt.setFilters(new Filter());                          
    holder.edt.addTextChangedListener(new Watcher());                          
    holder.edt.setText(“text”);                                                                             
    holder.edt.setSelection(text.length);               
    holder.edt.setSelectAllOnFocus(true);                      
    return convertView;
             }

    public class ViewHolder extends RecyclerView.ViewHolder 
    {                 
     public EditText edit;                          
     public ViewHolder(View itemView) 
     {                 
      super(itemView);         
      edt = (EditText) itemView.findViewById(R.id.edt);             
    }
             }

Answer 1

尝试添加

android:descendantFocusability="afterDescendants"

到你的listView

尝试这样做，

static boolean b= true;
if(b == true){
   et.requestFocus();
   b= false;
}
