我正在开发一个应用程序，它从Web服务获取一些数据并显示在列表视图中。我已经实现了一个由BaseAdapter扩展的自定义适配器。在getView()方法中，我也对原始进行了膨胀..这些都是完美的。
我的问题是我已经实现了代码，当用户单击列表项时显示一个对话框，但现在我想显示另一个对话框，其中有一个自定义列表（当点击是按钮时）。我还想在listview中显示一些数据。 [我有一个填充了我想要的数据的ArrayList]。我在我的适配器类中编写代码。任何人都可以告诉我如何做到这一点？
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() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
final int x = (int) getItemId(position);
/*Intent zoom=new Intent(mContext, Profile.class);
zoom.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
zoom.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(zoom);*/
// get the intent from the hashmap check if there is similar date and time.
//then store them in a list or array.
String getDate = (String) date.getText();
String getStartTime = startTime.getText().toString();
String getEndTime = endTime.getText().toString();
dialogshow(getDate,getStartTime,getEndTime);
}
});
vi.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String getFname = firstname.getText().toString();
Toast.makeText(parent.getContext(), "view clicked: "+getFname , Toast.LENGTH_SHORT).show();
//get the id of the view
//check the id of the request
//call the web service acording to the id
Intent zoom=new Intent(parent.getContext(), Profile.class);
parent.getContext().startActivity(zoom);
}
});
return vi;
}

你是在正确的轨道上，这是我用来动态显示一个带有项目列表的对话框。
作为参考，此处提出了类似的问题：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
}
希望这可以解决你的问题。

为了您的关注，我希望您知道创建自定义列表视图。
使用包含带有自定义列表视图的自定义对话框的下述代码。我希望你可以通过你的
执行适配器和模型部分 final Dialog new_dialog = new Dialog(getParent());
new_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
new_dialog.setContentView(R.layout.customize_dialog_list_view);
new_dialog.setCancelable(false);
cuc = new CommanUtilityClass();
SharedPreferences sp = getSharedPreferences("provider",0);
String services = sp.getString("services","");
Log.i("Servicesss",bAllServices);
TextView service = (TextView) new_dialog.findViewById(R.id.cdlv_service_provider);
TextView hour = (TextView) new_dialog.findViewById(R.id.cdlv_working_hours);
TextView appointment_time = (TextView) new_dialog.findViewById(R.id.cdlv_appoint_time);
TextView appointment_date = (TextView) new_dialog.findViewById(R.id.cdlv_appoint_date);
String[] ampm = myTiming[which].split(":");
Log.d("xxxooo", ampm[0]);
appointment_time.setText(Html.fromHtml("<b>Appointment time :</b>" + myTimingToShow[which].split("/")[0]));
appointment_date.setText(Html.fromHtml("<b>Appointment date :</b>" + selected));
service.setText(Html.fromHtml("<b>Service provider :</b>"+ cuc.toTheUpperCase(bsp_name)));
hour.setText(Html.fromHtml("<b>Working hours :</b>"+ cuc.toTheUpperCase(bsp_availability)));
lv = (ListView) new_dialog.findViewById(R.id.cdlv_list);
CustomDialogArrayAdapter cdaa = new CustomDialogArrayAdapter(getApplicationContext(),m_ArrayList);
lv.setAdapter(cdaa);
new_dialog.show();
ImageButton btn_cdlv_cancel = (ImageButton) new_dialog.findViewById(R.id.cdlv_cancel);
btn_cdlv_cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

}
});
