Question

我的应用有两个片段，可以作为标签进行转换。第一个片段使用自定义列表适配器显示列表视图中的项目列表。单击列表中的项目时，我想显示一个对话框来输入一些数据。这是应用程序的快照

以下是设置第一个片段的代码

private void setFragOne1() {
    String sql = "select admin_email, admin_name, admin_img, admin_contact, admin_status from links";
    cr  = sdb.rawQuery(sql, null);
    try{
        linksList = new ArrayList<>();
        while(cr.moveToNext()) {
            admin_email = cr.getString(0);
            admin_name = cr.getString(1);
            admin_img = cr.getString(2);
            admin_contact = cr.getString(3);
            admin_status = Integer.parseInt(cr.getString(4));
            linksList.add(new f1_row_model(admin_email, admin_name, admin_img, admin_contact, admin_status));
        }
        //last item for add new link
        linksList.add(new f1_row_model("","Click here to add link","","",-1));
        f1adapter = new f1_row_adapter(linksList, getContext());
        lv_all_links.setAdapter(f1adapter);

    }catch (Exception e){
        Log.e("SFO1", e.toString());
    }
}

以下是我的适配器中单击列表视图时调用的代码

protected void show_subscribe_form() {
    try {
        LayoutInflater inflater = (LayoutInflater) 
mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
        View layout;
        layout = inflater.inflate(R.layout.subscribe, (ViewGroup) 
findViewById(R.id.root), false);

        ed_subscription_email = (EditText) 
layout.findViewById(R.id.edEmail);
        ed_note = (EditText) layout.findViewById(R.id.edNote);

        //Building dialog
        AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
        builder.setView(layout);
        builder.setCancelable(false);
        builder.setTitle("Enter the Email Address to Link to");
        builder.setIcon(ContextCompat.getDrawable(mContext, 
R.drawable.linkto));
        builder.setPositiveButton("Subscribe", new 
DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        });
        builder.setNegativeButton("Cancel", new 
DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

        AlertDialog dialog = builder.create();
        dialog.show();
    }catch(Exception e){
        Toast.makeText(mContext, "ssf " + e.toString(), 
Toast.LENGTH_SHORT).show();
        Log.e("ssf",e.toString());
    }
}

我在这一行收到错误

layout = inflater.inflate(R.layout.subscribe, (ViewGroup) 
findViewById(R.id.root), false);

并且错误是“无法解析方法findViewById（int）”

我做错了什么，这里？

尝试更改

layout = inflater.inflate(R.layout.subscribe, (ViewGroup) 
findViewById(R.id.root), false);

要

layout = inflater.inflate(R.layout.subscribe,null);

从片段内的cutom列表适配器创建alertdialog
