I can able to show a customized listview with a bunch of textview on it as it's item but,I want to get the Name of the restauirants setOnItemClick on the List view.
e.g whenever I click Click on "Bar B Q","calcutta Food Court",it'll show me only "Bar B Q","calcutta Food Court" not other informations.
thnx in advance.Feel free to if u need anything.
"my application screen shot"
assume you've got method like getFoodJointname() in your Restaurent class, you can write the below in your onItemClick():
String hotelname = restaurentData.get(position).getFoodJointname();
makeAToast(hotelname);
this will work hopefully.
Restaurent rest= (Restaurent) foodJntListView.getSelectedItem();

I have one customdialog box which will appear on clicking the row of listview.And the data will display on customdialogbox from web service.Now ,if by mistake if i click twice, the customdialog box open twice.My custom dialog box is in Async class and i have call it on onPostexecute().
Every time i click on row of listview -it should called Async class in which customdialog box is there.
How to avoid to open it twice?
Please help.
I have checked some other condition but it is not working for me.
public void showCustomDialog() { // this is the dialog box i have created
// TODO Auto-generated method stub
final Dialog dialog = new Dialog(context);
final List<String> list=new ArrayList<String>();
list.add("Low");
list.add("Normal");
list.add("High");
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.customdialoguniversalappointment);

ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(context,
android.R.layout.simple_spinner_item, list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerappt.setAdapter(dataAdapter);
spinnerappt.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
int index = arg0.getSelectedItemPosition();
selected_item=arg0.getItemAtPosition(arg2).toString();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
System.out.println("APTCustomRequestResponse.runcustomuniversalappdata="+run_custom_universal_apptdata());
APTRequestCustomAdapter adap=new APTRequestCustomAdapter(context,run_custom_universal_apptdata());
listcustomuniversalappt.setAdapter(adap);
cancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.dismiss();
System.out.println("hello");
}
});
cancelappt.setOnClickListener(new OnClickListener() {

}
});
//confirm appt

// TODO Auto-generated method stub
if(APT_CustomRequestResponse.radiostring.equals("checked")){
showdialogforconfirmappointment();
}else{
Toast.makeText(context, "Please Select a Patient to book a Appointment",2000).show();
}
}
});
getsubject=subject.getText().toString();
if(!dialog.isShowing()||dialog==null){//here i am checking condition where it should appear or not
dialog.show();
System.out.println(isMatch);
}else{
dialog.dismiss();
}
}
and in onPost method i have called it:
public class APT_CustomRequestResponse extends AsyncTask<String,String,String>{
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
showCustomDialog();//here i am calling custom dialog box
#Override
protected String doInBackground(String... params) {
String hunt= GetAPT_RequestCustomdata();
return hunt;
}
}
}
This async class i am calling in other class where my actual listview is :
listview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
APT_CustomRequestResponse APT=new APT_CustomRequestResponse(MainActivity.this);
APT.execute();
Use below provided code for reference toward solving this issue.
// Keep this as member variable to the class
final Dialog dialog = new Dialog(context);
// your new method model
public void showCustomDialog() {
// Here check this
if(dialog != null && dialog.isShowing()){
// Decide if you want to display a new one, if yes then write below code first
dialog.dismiss();
dialog = null;
// Display a new dialog code here
}else{
// Dialog is no visible, diaply it here
}
}
Instead of try to avoid twice call of showCustomDialog() method try to avoid start AsyncTask again if task is already running on ListView row click. you can do this using AsyncTask.Status :
public boolean isfirsttimeclick=true;
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
APT_CustomRequestResponse APT=new APT_CustomRequestResponse(MainActivity.this);
if(isfirsttimeclick || APT.getStatus() == AsyncTask.Status.FINISHED){
APT.execute();
}else{
/// show message to user already running
}
}
You should not send a request to the server when item is clicked twice.
Either show a progress dialog in between while first request is sent that will prevent user from clicking at the list item again.
OR check in onItem click like #ρяσѕρєя K said just to add to that use following code define APT_CustomRequestResponse object outside of onItemClick and in your activity:
In activity:
APT_CustomRequestResponse APT=null;
onItemClick:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
if(MainActivity.this.APT==null||MainActivity.this.APT.getStatus() == AsyncTask.Status.FINISHED){
MainActivity.this.APT=new APT_CustomRequestResponse(MainActivity.this);
MainActivity.this.APT.execute();
}
}
EDIT
In you Async task create a boolean to know if execution is complete:
boolean finished=false;
And in post execute set it to true:
finished=true;
and finally do this in your onItemClick:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
if(MainActivity.this.APT==null||MainActivity.this.APT.finished){
MainActivity.this.APT=new APT_CustomRequestResponse(MainActivity.this);
MainActivity.this.APT.execute();
}
}
My need is to
create a dynamic spinner on a button click
select the spinner values and set the values into an edit text field.
For this I have created a dynamic spinner programatically. Put that code inside button click listener. Its working fine upto here.
but the setOnitemSelectedListener of the dynamic spinner is not at all working.. there are no errors in the Logcat... please help me..
------------ These are the methods inside onCreate ------------
Spinner spnOutHospitalList = new Spinner(Referance.this);
// list button on click event
btnList = (Button) findViewById(R.id.btn_list);
btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// function to create spinner dynamically
createDynamicSpinner();
}
});
// Out Hospital List Spinner on item click listener
spnOutHospitalList.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,int position, long arg3) {
// TODO Auto-generated method stub
outHospitalName = hospitalNameListArray.get(position);
outHospital.setText(outHospitalName);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
------------ These are the functions outside onCreate but inside the Activity------------
// to create spinner dynamically
private void createDynamicSpinner() {
// TODO Auto-generated method stub
spnOutHospitalList.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
loadOutHospitalListSpinner();
spnOutHospitalList.performClick();
}
// to load out hospital/ clinic data into spinner
private void loadOutHospitalListSpinner() {
// TODO Auto-generated method stub
try {
if (getFirstRun()) {
sampleDB = dbAdapter.getDatabase();
setRunned();
}
else {
sampleDB = dbAdapter.getWritableDatabase();
}
Cursor c1 = sampleDB.rawQuery("select DISTINCT EPR_OUT_HOSPITAL from EMR_PT_REFERNCE",null);
System.out.println("count is " + c1.getCount());
if (c1 != null && c1.getCount() != 0) {
hospitalNameListArray.clear();
if (c1.moveToFirst()) {
do {
hospitalNameListArray.add(c1.getString(c1.getColumnIndex("EPR_OUT_HOSPITAL")));
} while (c1.moveToNext());
}
}
c1.close();
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, hospitalNameListArray);
// dropdownlist
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spnOutHospitalList.setAdapter(dataAdapter);
}
catch (Exception e) {
// TODO: handle exception
System.out.println("CAT LIST ERROR IS: " + e.getMessage());
}
}
Try this
Write setOnItemSelectedListener inside createDynamicSpinner
private void createDynamicSpinner() {
//Remove this line from top in your code and add here
Spinner spnOutHospitalList = new Spinner(Referance.this);
spnOutHospitalList.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
//Pass Spinner Object to this function to load data in it!
loadOutHospitalListSpinner(spnOutHospitalList);
spnOutHospitalList.performClick();
spnOutHospitalList.setOnItemSelectedListener(new OnItemSelectedListener() {

outHospitalName = hospitalNameListArray.get(position);
outHospital.setText(outHospitalName);
}
#Override

You should probably use a Dialog instead of a Toast.
Dialog is designed for more interactive pop-ups, where-as a toast is really designed to display a quick text message.
I really don't think you should use a toast for this kind of user interface. If you look at the documentation it says:
A toast notification is a message that pops up on the surface of the window. It only fills the amount of space required for the message and the user's current activity remains visible and interactive. The notification automatically fades in and out, and does not accept interaction events.
Toast Notifications
What you want is probably a Dialog
I have listed a list with custom adapter to display different images in each list item and succeeded.
Now i need to add a onitemclick listener for that list.
Unable to access the id because the list id is - "#+id/android:list".
Unable to identify this id.
Any ideas please share.
You will get some more idea when you see this below link
Click here for the example i tried.
In the given example, the ListActivity is extended in CustomAdapterActivity.java
so its simple to get Click events of the list items by writing list item click listener
and to write onClickListener you need to do
like this in that class.
**
public class Test extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
ListView lv = getListView();
lv.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
}
}

I want it where when someone clicks an option in a Spinner, it opens another spinner with more options. Also, is there a way for an "Other" option to open an EditText where someone can input their selection if theirs isn't available in the Spinner?
Example:
Spinner 1 has these options:
iOS
Android
And if they select iOS, another spinner comes up immediately where the options are all the iPhone versions. (i.e., titled "Which iPhone do you have?")
And if they select Android, it does the same thing, but with Android devices.
AND if their phone isn't on the second spinner, they type the model of their phone in.
How could I do this if I have the first spinner already in my code?
P.S., if needed, I can post the code for the first spinner, though it's pretty standard.
Basically build your second spinner programmatically depending on which option they choose. I'd add "other" to each second spinner. If they choose "other" then you can display the text box.
I hope this will be useful to you.
Try this Code...
