本文介紹了如何將自定義列表視圖設置為對話框的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！

問題描述

我正在開發一個應用程序，該應用程序從 Web 服務獲取一些數據并顯示在列表視圖中.我已經實現了一個由 BaseAdapter 擴展的自定義適配器.在 getView() 方法中，我也對原始數據進行了充氣.這些都工作得很好.

I am developing a application which fetches some data from a web service and displays in a list view. I have implemented a custom adapter which is extended by BaseAdapter. In the getView() method I inflate the raw also.. Those are working perfectly.

我的問題是我已經實現了代碼以在用戶單擊列表項時顯示一個對話框，但現在我想顯示另一個對話框，其中包含一個自定義列表(單擊是"按鈕時).我還想在該列表視圖中顯示一些數據.[我有一個 ArrayList 填充了我想要的數據].我正在我的適配器類中編寫代碼.誰能給我一些想法怎么做?

My problem is I have implemented code to show a dialog box when user click on an list item, but now I want to show another dialog box which has a custom list inside it (when Yes button clicked). I also want to show some data in that listview. [I have a ArrayList filled with the data that I wanted] . I'm writing the code inside my adapter class. Can anyone give me some idea how to do it ?

這是我的代碼:

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();
                    }
                });
