In my code i am using sms manager for sending sms which are the thing getting from my listview,it has to send sms,but after clicking the ok button,nothing is work, dialog dismiss only working,not sms manager is not working.
smsManager.sendTextMessage("phoneNo", null, "sms message", null, null);
"phoneNo" in this place specify the number for which you want to send sms
ok what is that selected data does that contain the phone numbers or the some text data that needs to be sent as a message. see "phoneNo" is string what you are passing. In your phone in place of number if you type phoneNo how will it send to which number will it send. that 1st parameter is the phone number to which you want to send sms. if you are selecting the phone number from the list get that to a variable and put that variable in place of "phoneNo"
if you want to enter the number when the alert is shown then here is the code
private void showAlertView(String str) {
final EditText input = new EditText(YOURACTIVITYNAME.this);
AlertDialog alert = new AlertDialog.Builder(YOURACTIVITYNAME.this)
if (TextUtils.isEmpty(str)) {
alert.setTitle("Not Selected");

I have an activity with multiple EditText, after entered data and click button SAVE for save them in Database(Mysql) it open Fragment which have ListView populated with this data from database.
PROBLEM:
ListView isn't showing new data that I have entered in activity!!!, even the new data is added im my ArrayList correctly.
But when I start this Fragment for the second time it shows the Listview with new data correctly.

in my Adapter
public void addAll(ArrayList<SymbMoneItems> result) {

Thanks for any help.
Setting data using "=" doesn't actually have any change on dataset for adapter.
Change your addAll() method like below:
public void addAll(ArrayList<SymbMoneItems> result) {
this.listSymb.clear();
this.listSymb.addAll(result);
this.notifyDataSetChanged();
}
Hey every one has i am create rename application in android ,I will set a Edit-text box in set error message using without toast using Alert Dialog box
Sample Code :
AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
alert.setTitle(R.string.rename_title);
folderManager = new FolderManager(getActivity());
folderManager.open();
Cursor c = folderManager.queryAll(itemPos);
if (c.moveToFirst()) {
do {
Newnamefolder = c.getString(1);
} while (c.moveToNext());
}
// Set an EditText view to get user input
final EditText input = new EditText(getActivity());
input.setText(Newnamefolder);
alert.setView(input);
alert.setPositiveButton(R.string.rename_position_button, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton)
{
Newnamefolder = input.getText().toString();
String Mesage_one = getResources().getString(R.string.folder_already_exit);
String Mesage_two = getResources().getString(R.string.types_minimum_eight_charcter);
String Mesage_three = getResources().getString(R.string.folder_empty);
String Matchnamerename = folderManager.getmatchfoldername(Newnamefolder);
if(Newnamefolder.equals(Matchnamerename))
{
input.setError(Mesage_one);
}
else if(Newnamefolder.length()>12)
{
input.setError(Mesage_two);
}
else if(Newnamefolder.equals(""))
{
input.setError(Mesage_three);
}
else
{
int newfolder = folderManager.update(itemPos,Newnamefolder);
reload();
}
}
});
alert.show();
But the problem once in click the OK button Don't show error message to exit the Alert Dialog box...
give me any solution ... Friends ?
You can extend Dialog and create your own dialog
public class CustomDialog extends Dialog implements View.OnClickListener {
private boolean success = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_dialog);
Button positive = (Button) findViewById(R.id.button_positive);
Button negative = (Button) findViewById(R.id.button_negative);
EditText field = (EditText) findViewById(R.id.field);
positive.setOnClickListener(this);
negative.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch(v.getId()) {
case R.id.button_positive:
onPositiveButtonClicked();
break;
case R.id.button_negative:
//onNegativeButtonClicked();
break;
}
}
private void onPositiveButtonClicked() {
if(verifyForm()) {
success = true;
dismiss();
}
}
public boolean isSuccess() {
return success;
}
private boolean verifyForm() {
boolean valid = true;
/* verify each field and setError() if not valid */
if(!TextUtils.isEmpty(field.getText())) { //or any other condition
valid = false;
field.setError("error message");
}
return valid;
}
}
You can show your CustomDialog like this
final CustomDialog customDialog = new CustomDialog();
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
if(customDialog.isSuccess()) {
//update your folder manager
}
}
}
customDialog.show();

This code is working fine on my phone galaxy note 2(custom rom of note 4.. Android 4.4.4).By fine I mean I can type in edittext and popupwidow shows up after 3rd text(because of condition I have put) and I can select an option from the popupwindow. When I try to run the code on any other phone like galaxy grand then callback to ItemsDropdownOnItemClickListener is not registered and I can only scroll the popupwindow and keep on typing in edittext but cannot select any of the options in the popupwindow. If I set popupWindowItems.setFocusable(false) to true i.e popupWindowItems.setFocusable(true), and then as soon as I type 3rd letter in edittext,edittext looses focus and popwindow gains it. Now I can select anything.. But now I cannot continue to type in edittext.I have to manually select edittext and type.
Now I want that after tying 3rd word in edittext a popupwindow should appear(which currently is appearing) and edittext doesn't loose focus(so that i can continue typing).. Further if I select anything from popupwindow ,ItemsDropdownOnItemClickListener should be called which is currently being not called in other phones when popupWindowItems.setFocusable(false);
I am doing this to load data from sqlite database and show in popupwindow once the user types 3rd word. Any suggestion is recommended
Edit: Problem solved. Now using AutoComplete TextView
I'm new to android development having some problems. I created a list view that is based on the user input. User has to enter a category in a dialog box and then it's added into the list. Works like a charm. The question is how do I retain those categories once the user exits from an app and starts it again ? When the user starts the app, the list is blank. Do I have to create a preference screen or something to save what the user types ? Here is my code:
public class MainActivity extends Activity {
final Context context = this;
ArrayAdapter<String> arrayAdapter;
ArrayList<String> listItems = new ArrayList<String>();
ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lv = (ListView)findViewById(R.id.listView1);
arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, listItems);
lv.setAdapter(arrayAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.menu_add_cat:
LayoutInflater li = LayoutInflater.from(context);
View promptAdd = li.inflate(R.layout.prompt_add, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
//set prompts.xml to alertDialogBuilder
alertDialogBuilder.setView(promptAdd);
final EditText etAddCat = (EditText)promptAdd.findViewById(R.id.etDialogInput);
//set a dialog message
alertDialogBuilder.setPositiveButton("Done", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
/*
* add a cat here
*/
String input = etAddCat.getText().toString();
if(null != input && input.length() > 0){
listItems.add(input);
arrayAdapter.notifyDataSetChanged();
}else{
Toast.makeText(getApplicationContext(), "Please enter a new category", Toast.LENGTH_LONG).show();
}
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
break;
}
//return super.onOptionsItemSelected(item);
return true;
}
}// end of MainActivity
You can save it in SQLite DB, use CursorAdapter for your list view.
If the amount of data you want to save is relatively small you can use SharedPreferences to save the String data in your onClick method.
#Override
public void onClick(DialogInterface dialog, int which) {
String input = etAddCat.getText().toString();
if(null != input && input.length() > 0){
listItems.add(input);
// Add all string data to List<String> listItem
listItem.add(input);
arrayAdapter.notifyDataSetChanged();
}else{
Toast.makeText(getApplicationContext(), "Please enter a new category", Toast.LENGTH_LONG).show();
}
}
When the user leaves your activity, use the onStop() callback method to save your List<Strings> and store it through SharedPreferences.
#Override
private void onStop() {
super.onStop();
SharedPreferences.Editor editor = mSharedPreferences.edit();
editor.putString(getResources().getString(R.string.list_of_strings), new HashSet<String>(listItem));
editor.commit;
}
Using the onStart() callback, initialize your List and SharedPreferences. When the user navigates to your activity, your list will be reinitialized when it was saved via onStop().
Finally, iterate through your list, add your items to your ArrayList', create yourArrayAdapter` and set it to your list.
#Override
private onStart(){
super.onStart();
SharedPreferences mSharedPreferences;
mSharedPreferences = this.getApplicationContext().getSharedPreferences("MyPreferences", 0);
List<String> listItems = new ArrayList<String>(mSharedPreferences.getStringSet("ListOfStrings", null));
ListIterator li = listItem.listIterator(0);
while (li.hasNext()) {
newStatusList.add((String)li.next());
}
arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, listItems);
lv.setAdapter(arrayAdapter);
}
Hi I was wondering how I can get my Search Activity to return a result back to the Activity that started it.
I currently have a Search Dialog implemented (meaning the search Activity starts once the Search button on the phone is clicked).
Here is my code for the Search activity which is a list view.
public class ItemFinder extends ListActivity {
public static final int REQUEST_CODE = 1; // get it?
Vector<String> upcCodes;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search);
upcCodes = new Vector<String>();
ListView lv = (ListView) findViewById(android.R.id.list);
lv.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
String upc = upcCodes.elementAt(position);
setResult(RESULT_OK);
}
});
// Get the intent, verify the action and get the query
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
ProgressDialog dialog = ProgressDialog.show(ItemFinder.this, "Searching",
"Searching. Please wait...", true);
performSearch(query);
dialog.hide();
dialog.dismiss();
}
}
public void performSearch(String query){
String result = new SmartShopClient().SearchItems(query);
List<String> dataList = new ArrayList<String>();
String _parsedResult[] = result.split("\\n");
for( int i = 0; i<_parsedResult.length; i++){
String _splitData[] = _parsedResult[i].split("\\|");
String itemName = _splitData[0];
String itemUPC = _splitData[1];
dataList.add(itemName);
upcCodes.add(itemUPC);
}
ArrayAdapter<String> arr = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, dataList);
this.setListAdapter(arr);
}
}
So the search is working all fine and dandy, but I want it so when I click one of the results in the ListView, for it to return data back to the main activity with some data, say the name of the clicked searched result.
Thanks.
What you want to do is launch the search using startActivityForResult. See an explanation here.
This way, you can pass your search results back to the activity which launched it.
That would happen in your setOnItemClickListener method, where you could launch an explicit intent naming the desired activity with extra data.
Edit : I'm not quite sure of how startActivityForResult() would be implemented since we're talking about the search activity of the application, meaning it's launched by the Android search specific module ; that's why i suggested the above solution.
I ended up doing this:
public boolean onSearchRequested() {
askSearchQuery();
return true;
}
public void sendSearchRequest(String query){
Intent mIntent = new Intent(this, ItemFinder.class);
mIntent.setAction(Intent.ACTION_SEARCH);
mIntent.putExtra(SearchManager.QUERY, query);
startActivityForResult(mIntent, ItemFinder.REQUEST_CODE);
}
public void askSearchQuery() {
final EditText input = new EditText(SmartShop.this);
AlertDialog.Builder adb = new AlertDialog.Builder(SmartShop.this);
adb.setTitle("Search Items");
adb.setMessage("Please input the name of the item you are looking for.");
adb.setView(input);
adb.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
Editable upc = input.getText();
sendSearchRequest(upc.toString());
dialog.cancel();
}
});
adb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
adb.create().show();
}
And then I hooked the
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
