android - 如何将自定义 ListView 设置为对话框

Question

我正在开发一个应用程序，它从网络服务中获取一些数据并显示在 ListView 中。我已经实现了一个由 BaseAdapter 扩展的自定义适配器。在 getView() 方法中，我也对原始文件进行充气。这些工作正常。

我的问题是我已经实现了当用户单击列表项时显示对话框的代码，但现在我想显示另一个对话框，其中有一个自定义列表(当单击"is"按钮时)。我还想在该 ListView 中显示一些数据。 [我有一个 ArrayList，里面装满了我想要的数据]。我正在我的适配器类中编写代码。任何人都可以告诉我如何去做吗？

这是我的代码:

public class NewsRowAdapter extends BaseAdapter  {


private Context mContext;
private Activity activity;
private static LayoutInflater inflater=null;
private ArrayList<HashMap<String, String>> data;
int resource;
    //String response;
    //Context context;
    //Initialize adapter
    public NewsRowAdapter(Context ctx,Activity act, int resource,ArrayList<HashMap<String, String>> d) {
        super();
        this.resource=resource;
        this.data = d;
        this.activity = act;
        this.mContext = ctx;
        inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    }


    public void dialogshow(final String Date,final String Start,final String End){

        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(activity);
        alertDialogBuilder.setTitle("Confirm your Action!");

        // set dialog message
        alertDialogBuilder
            .setMessage("Click yes to exit!")
            .setCancelable(false)
            .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int id) {
                    // if this button is clicked, close
                    // current activity
                    //MainActivity.this.finish();

                //  Toast.makeText(mContext, "Yes clicked", Toast.LENGTH_LONG).show();

                    //check similer records

                //  ShortList sh = new ShortList();

                //  ArrayList<HashMap<String, String>> duplicateList; 
                //  duplicateList=sh.getDuplicated(Date, Start, End);


                    //if duplicates > 1 then show the popup list
            //      if(duplicateList.size()>1){
                    AlertDialog.Builder alertDialogBuilder2 = new AlertDialog.Builder(activity);

                    LayoutInflater infl = activity.getLayoutInflater();




                    //View vi = infl.inflate(id, root)





                    alertDialogBuilder2.setView(infl.inflate(R.layout.dialog_row, null))
                    .setPositiveButton("Accept", new DialogInterface.OnClickListener() {

                                @Override
                                public void onClick(DialogInterface dialog, int which) {
                                    // TODO Auto-generated method stub
                                    Toast.makeText(mContext, "Accepted", Toast.LENGTH_LONG).show();
                                }
                            })
                            .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

                                @Override
                                public void onClick(DialogInterface dialog, int which) {
                                    // TODO Auto-generated method stub
                                    dialog.dismiss();
                                }
                            });

                    alertDialogBuilder2.show();


                //  }



                }
              })
              .setNegativeButton("No",new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,int id) {
                        // if this button is clicked, just close
                        // the dialog box and do nothing
                        dialog.cancel();
                    }
                });
        alertDialogBuilder.show();

    }



@Override
public View getView(final int position, View convertView, final ViewGroup parent) {


    View vi = convertView;
    if(convertView==null)
        vi = inflater.inflate(R.layout.row,null);


        final TextView firstname = (TextView) vi.findViewById(R.id.fname);
        final TextView lastname = (TextView) vi.findViewById(R.id.lname);
        final TextView startTime = (TextView) vi.findViewById(R.id.stime);
        final TextView endTime = (TextView) vi.findViewById(R.id.etime);
        final TextView date = (TextView) vi.findViewById(R.id.blank);
        final ImageView img = (ImageView) vi.findViewById(R.id.list_image);


        HashMap<String, String> song = new HashMap<String, String>();
        song =data.get(position);

        firstname.setText(song.get(MainActivity.TAG_PROP_FNAME));
        lastname.setText(song.get(MainActivity.TAG_PROP_LNAME));
        startTime.setText(song.get(MainActivity.TAG_STIME));
        endTime.setText(song.get(MainActivity.TAG_ETIME));
        date.setText(song.get(MainActivity.TAG_DATE));
        //imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL), img);

        Button accept = (Button) vi.findViewById(R.id.button1);
        accept.setOnClickListener(new OnClickListener() {

                // get the intent from the hashmap check if there is similar date and time.

            }
        });

        return vi;


}

你在正确的轨道上，这是我用来动态显示其中包含项目列表的对话框的方法。

作为引用，这里提出了一个类似的问题:Android custom list dialog

    //String[] list_data; Preloaded with a String array

    final CharSequence[] items = new CharSequence[list_data.length];

            for (int i = 0; i < list_data.length; i++) {
               items[i] = list_data[i];
            }

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Select the data you want");
    builder.setItems(items, new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            //Get the id of the item
            diag_callback();

        }

    });

    AlertDialog alert = builder.create();
    alert.show();

}

public void diag_callback() {
    //Do someting when the user has made his selection
}

希望这能解决您的问题。
