如何在列表视图中获取可编辑的编辑文本

-4

我已经创建了自定义列表视图。在其布局中创建了一个编辑文本。但我无法编辑这个编辑文本。如何在列表视图中获取可编辑的编辑文本

list.setAdapter(new yourAdapter(NewActivity.this, new String[] { "test1", 
      "test2","test3" }));

和我yourAdapter类是

class yourAdapter extends BaseAdapter { 

Context context; 
String[] data; 
private static LayoutInflater inflater = null; 

public yourAdapter(Context context, String[] data) { 
    // TODO Auto-generated constructor stub 
    this.context = context; 
    this.data = data; 
    inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
} 

@Override 
public int getCount() { 
    // TODO Auto-generated method stub 
    return data.length; 
} 

@Override 
public Object getItem(int position) { 
    // TODO Auto-generated method stub 
    return data[position]; 
} 

@Override 
public long getItemId(int position) { 
    // TODO Auto-generated method stub 
    return position; 
} 



@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 
    View vi = convertView; 
    if (vi == null) 
     for(int i =0; i<=getCount();i++){ 
      if(data[position].equals("grouped")){ 
       vi = inflater.inflate(R.layout.multipleselect, null); 
      } 
      else if(data[position].equals("kuchbhi")) 
       vi = inflater.inflate(R.layout.yes_or_no, null); 
      else { 
       vi = inflater.inflate(R.layout.write_answer, null); 
       //edit_text 
       EditText edit_text = (EditText) vi.findViewById(R.id.edit_text); 
      } 


     } 

    /* TextView text = (TextView) vi.findViewById(R.id.text); 
    text.setText(data[position]);*/ 
    return vi; 
}

}

我不能edit_text编辑。当我点击编辑文本键盘打开，但没有显示内部编辑文本。

上面的代码应该会崩溃棉花糖。您需要使用新的权限系统。 –

棉花糖手动请求权限。毫无疑问，您必须已经在清单文件中添加了位置权限，但现在您还需要添加一些代码以手动请求权限。你可以使用这个库 https://github.com/Karumi/Dexter
