我正在开发一个应用程序，该应用程序从 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，我也对原始数据进行了充气.这些都工作得很好.
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.
我的问题是我已经实现了代码以在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，其中包含一个自定义列表(单击是"按钮时).我还想在该列表视图中显示一些数据.[我有一个 ArrayList 填充了我想要的数据].我正在我的适配器类中编写代码.谁能给我一些想法怎么做?
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 ?
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;
}
你在正确的轨道上，这是我用来动态显示一个包含项目列表的对话框.
You are on the right track, Here is what i used to dynamically display a Dialog with a list of items in it.
这里提出了一个类似的问题作为参考:Android 自定义列表对话框
For reference a similar Question was asked here : 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.
Hope this sorts out your problem.
