Question

我从webservice获取一些细节，我需要动态显示这些细节与左侧相关的复选框（使用java代码）。我已经正确地将所有细节映射到Hashmap Arraylist，接下来该做什么就是显示警报箱的所有细节，在我的代码中定义。我尝试了很多。任何人都可以帮助我任何帮助都会非常值得.......

selectButton.setOnClickListener(new View.OnClickListener() {


                            private Builder mDialog;

                            @Override
                            public void onClick(View v)  {

                                Log.e(tag,"alertbox for onclickworked");
                                Context c =getParent();
                                this.mDialog = new AlertDialog.Builder(c);

                                alertDialog = mDialog.create();
                                // Setting Dialog Title
                                 alertDialog.setTitle("Intrested In");


                                 new Serviceclass().execute();




                        // Setting Icon to Dialog
                        alertDialog.setIcon(R.drawable.gate_logo);


                        alertDialog.show();

HERE I NEED TO WRITE THE CODE
                                     }

                             }

提前谢谢.....

您有Web请求，可以在对话框中显示和显示记录。在这里我建议你。

1.使用DialogFragments.
2.内部片段制作一个列表视图，根据您的设计创建自定义适配器。
3.在片段内部创建Web请求。
4。为方便起见，您可以阅读本教程Android DialogFragment and ListView
