java在显示DialogFragment活动时出错

Question

通过以下代码，我得到了这个错误：

error:';' expected dialogFragment.show((Activity) _context).getSupportFragmentManager(), "Dialog"));

@Override
public View getChildView(int groupPosition, final int childPosition,
                         boolean isLastChild, View convertView, ViewGroup parent) {

    final String childText = (String) getChild(groupPosition, childPosition);

    if (convertView == null) {
        LayoutInflater infalInflater = (LayoutInflater) this._context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.list_item, null);
    }

    TextView txtListChild = (TextView) convertView.findViewById(R.id.lblListItem);
    Button btnListChild = (Button) convertView.findViewById(R.id.btn);
    btnListChild.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            CustomDialogClass dialogFragment = new CustomDialogClass();
            dialogFragment.show((Activity) _context).getSupportFragmentManager(), "Dialog"));
        }
    });

    txtListChild.setText(childText);
    return convertView;
}

改变对话片段。显示（（活动）_上下文）。getSupportFragmentManager（），“对话框”）； 使分裂。显示（（活动）_上下文。getSupportFragmentManager（），“对话框”）
