I'm trying to have my AlertDialog with a custom list view but can't seem to get it to show or run without error.
private void buildDialog(){
int selectedItem = -1; //somehow get your previously selected choice
LayoutInflater inflater = ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE));
View customView = inflater.inflate(R.layout.listview, null, false);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(customView);
builder.setTitle("Select Weapon").setCancelable(true);
builder.setSingleChoiceItems(inventory, selectedItem, "Desc", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which)
{
ListView lv = ((AlertDialog) dialog).getListView();
itemId = lv.getAdapter().getItemId(which);
new changeEQ().execute();
}
});
dialog = builder.create();
}
This is my AlertDialog but can't figure out what to add to get my custom layouts, listview & listrow to be used. I've looked around at guides online but nothing they show seems to work for me. IE I must be doing something wrong.
EDIT: changed code to include answer but has no change on what is showed on screen. No errors yet no change in look.
If you have a custom layout that you want to pass to your AlertDialog try:
LayoutInflater inflater = ((LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE));
View customView = inflater.inflate(R.layout.custom_dialog, null, false);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(customView);
If you want to define listeners try:
ListView list = (ListView) customView.findViewById(R.id.listView1);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Do as you please
}
});

LayoutInflater inflater = getLayoutInflater();
View convertView = (View) inflater.inflate(R.layout.custom, null);
alertDialog.setView(convertView);
alertDialog.setTitle("Select City");
ListView lv = (ListView) convertView.findViewById(R.id.listView1);
ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,citiesInSpinner);
lv.setAdapter(adapter);
/* alertDialog.setItems(citiesInSpinner, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {

Simply use
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
City city = citiesInSpinner.get(position)
//get your id -> city.Id
}
});
Hello guys i would like to display more than one item horizontally in a single list. This items are picked from the dialog box that has two button ok and cancel. When you click okay it should pick the values from the edit text and a string value from the dialog and display in the list horizontally.
Array List Adapter
public class VehicleListAdapter extends ArrayAdapter<String> {
private Context context;
private List<String> vehicle_no;
public VehicleListAdapter(Context context, int resource, List<String> objects) {
super(context, resource, objects);
this.context = context;
this.vehicle_no = objects;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//get the vehicle number we are displaying
String my_vehicle = vehicle_no.get(position);
//get the inflater and inflate the XML layout for each item
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.vehicle_num_layout, null);
TextView txt_vehicle_num = (TextView) view.findViewById(R.id.txt_vehicle_num);
txt_vehicle_num.setText(my_vehicle);
return view;
}
}
Activity with the list
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// get prompts.xml view
LayoutInflater li = LayoutInflater.from(context);
View promptsView = li.inflate(R.layout.prompts, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set prompts.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialogUserInput);
// set dialog message
alertDialogBuilder
.setCancelable(false)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// get user input and set it to result
// edit text
if(userInput.getText().toString().trim().length()==0) {
userInput.setError("Vehicle Number Required");
focus.start();
String stime = focus.getText().toString();
}
else {
result.setText(userInput.getText());
ListView list = (ListView) findViewById(R.id.list);
vehicle_list.add(userInput.getText().toString().trim());
VehicleListAdapter listAdapter = new VehicleListAdapter(StartWatch.this, 0, vehicle_list);
list.setAdapter(listAdapter);
}
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
});
First of all, why you are creating new listview every time when user hit ok of dialog. Remove this line ListView list = (ListView) findViewById(R.id.list); from dialog positive button click.
Add line as shown below after your code in positive button click
VehicleListAdapter listAdapter = new VehicleListAdapter(StartWatch.this, 0, vehicle_list);
list.setAdapter(listAdapter);
listAdapter.notifyDataSetChanged(); // Add this line to tell adapter that data has been changed
Im trying to get the content of the editText, but idont know how to do it. Please help me in this.(Im using the method showDialog)
protected Dialog onCreateDialog(int id, Bundle args)
{
AlertDialog.Builder builder2 = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
builder2.setView(inflater.inflate(R.layout.dialog_search_teacher,null));
final EditText price,city;
price=(EditText)findViewById(R.id.price_search);
city=(EditText)findViewById(R.id.city_search);
builder2.setPositiveButton("Serach", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
serach(city.getText().toString(),price.getText().toString());
}
});
builder2.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
AlertDialog alert2 = builder2.create();
return(alert2);}
If you need to get the text from the EditText you have to do this:
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_search_teacher, null);
city=(EditText)view.findViewById(R.id.city_search);
and then, on the onclick() method you have to retrieve the text:
city.getText().toString();
but if you want to pass the string to the parent class you have to do an interface like this:
http://developer.android.com/training/basics/fragments/communicating.html
You have to find editText id like this
price=(EditText)builder2.findViewById(R.id.price_search);
You should declaration your editText under the dialog method like,
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_search_teacher, null);
city=(EditText)view.findViewById(R.id.city_search);
After that, while doing onClick listener for postive button, you can get the content of editText using
city.getText().toString();
Hope this will help you.
i am displaying a custom dialog for user input on top of my list view activity layout. But when i try to refer the edit text in onCreateDialog() method, its always coming as blank. Below is my code, appreciate if someone can point out where i am doing wrong -
public class QuestionDialog extends DialogFragment
{
public Dialog onCreateDialog(Bundle savedInstanceState)
{
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
// Inflate and set the layout for the dialog
final View v =inflater.inflate(R.layout.ques_dialog,null);
builder.setView(inflater.inflate(R.layout.ques_dialog, null))
.setTitle("Title Message!")
.setCancelable(true)
.setPositiveButton("GO", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int whichButton)
{
EditText et1 = (EditText)v.findViewById(R.id.et1);
// here not able to get the data from edit text
String s1 = et1.getText().toString().trim();
Log.d("debug","data -"+s1+" and length"+s1.length());
.... rest code goes here
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int whichButton)
{
..rest code goes here
}
});
return builder.create();
}
}
That is happening because of this lines:
final View v =inflater.inflate(R.layout.ques_dialog,null);
builder.setView(inflater.inflate(R.layout.ques_dialog, null))
You first inflate the v View and then set as the content of the dialog a newly inflated view(so in the end you end up looking for a view which isn't the actual content of the dialog). Use this:
final View v =inflater.inflate(R.layout.ques_dialog,null);
builder.setView(v);
I have ListActivity , onClick of each item a Custom Dialog appears.Custom Dialog contains spinner and EditText Now i am not able to get the value of EditText, while debug value of EditText is coming as blank or "".
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
positionList=position;
HashMap<String,Object>temp =(HashMap<String ,Object>)list.get(position);
LayoutInflater inflater = (LayoutInflater) CommonScreen6.this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.answer_screen,null);
AlertDialog.Builder alertDialog=new AlertDialog.Builder(CommonScreen6.this);
alertDialog.setTitle("Select Option");
alertDialog.setView(layout);
Spinner answerList=(Spinner)layout.findViewById(R.id.spinnerAnswerList);
ArrayAdapter<String> adapterAnswerType = new ArrayAdapter<String> (CommonScreen6.this, android.R.layout.simple_spinner_item,(ArrayList<String>)temp.get(Constants.answerDesc));
adapterAnswerType.setDropDownViewResource(android.R.layout.select_dialog_singlechoice);
answerList.setAdapter(adapterAnswerType);
answerList.setOnItemSelectedListener(this);
ArrayList<String> answerDescList=(ArrayList<String>)temp.get(Constants.answerDesc);
answerList.setSelection(answerDescList.indexOf(temp.get(Constants.defaultAnswerDesc)));
alertDialog.setPositiveButton("Submit",new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
LayoutInflater inflater = (LayoutInflater) CommonScreen6.this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.answer_screen,null);
EditText editText=(EditText)layout.findViewById(R.id.remark);
String remark=editText.getText().toString();
HashMap<String,Object>temp =(HashMap<String ,Object>)list.get(positionList);
temp.put(Constants.remark, remark);
adapter.notifyDataSetChanged();
}
});
}
The reason that you are not getting any values is because you are reinflating the layout just before you read the values, thus resetting values to the defaults.
I suppose that you would like to findViewById on the v argument that was given to the onListItemClick method, instead of reinflating the layout.
That is, instead of
LayoutInflater inflater = (LayoutInflater) CommonScreen6.this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.answer_screen,null);
EditText editText=(EditText)layout.findViewById(R.id.remark);
try something like
EditText editText=(EditText)v.findViewById(R.id.remark);
You might need to make the v variable final, in order for this to work.
I hope this helps.
