AlertDialog with LinearLayout should not dismiss on button click

I only want my AlertDialog to be dismissed when certain conditions are met (when name and surname given are valid) - else it should always be on top of the parent view. My code is this:
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
final TextView instructions = new TextView(this);
instructions.setText(R.string.alert_enter_data);
final EditText name = new EditText(this);
name.setHint(R.string.name);
final EditText surname = new EditText(this);
surname.setHint(R.string.surname);
LinearLayout ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.addView(instructions);
ll.addView(name);
ll.addView(surname);
alert.setView(ll);
alert.setNeutralButton(R.string.enter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String name_txt = name.getText().toString();
String surname_txt = surname.getText().toString();
if ((name_txt.length() > 1) && (surname_txt.length() > 1)) {
dialog.dismiss();
}
}
});
final AlertDialog alert_dialog = alert.create();
alert_dialog.setCanceledOnTouchOutside(false);
alert_dialog.show();
With this code the AlertDialog disappears when the button is pressed, regardless of the input text. I then tried this:
alert_dialog.setOnShowListener(new DialogInterface.OnShowListener() {
#Override
public void onShow(DialogInterface dialog) {
Button b = alert.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String name_txt = name.getText().toString();
String surname_txt = surname.getText().toString();
String email_txt = email.getText().toString();
String cellphone_txt = cellphone.getText().toString();
String postcode_txt = postcode.getText().toString();
if ((name_txt.length() > 1) && (surname_txt.length() > 1) && (email_txt.length() > 4)) {
if (debug_mode) {Log.i(TAG,"clause 1");}
String data_to_upload = name_txt + ", " + surname_txt + ", " + email_txt + ", "+ cellphone_txt + ", " + postcode_txt + "\n";
// upload_to_github(data_to_upload);
alert_dialog.dismiss();
}
}
});
}
});
But this way I get not Button at all. The Alert Dialog only contains the EditText fields.

alert.setNeutralButton(R.string.enter, new DialogInterface.OnClickListener() {
and
Button b = alert.getButton(AlertDialog.BUTTON_POSITIVE);
both are different buttons.
try
Button b = alert.getButton(AlertDialog.BUTTON_NEUTRAL);

Inserting Data into database from input alert dialog box

Its a game in which at the end activity the score is displayed But before that the input alert box is displayed where user need to add their name,and that name and score should go to the database. score is getting stored but not the name. how to get name from input alert dialog box and set it on db.insertScore(Score,Name).how am i suppose to add input value of alert dialog box to extra.getString(""); there is getter & setter method.here is my code
Bundle extra = getIntent().getExtras();
if (extra != null)
{
showInputDialog();
final String Name=extra.getString("");
final int Score = extra.getInt("SCORE");
final int totalQuestion = extra.getInt("TOTAL");
int correctAnswer = extra.getInt("CORRECT");
txtTotalScore.setText(String.format("SCORE : %d", Score));
txtTotalQuestion.setText(String.format("PASSED : %d/%d", correctAnswer, totalQuestion));
progressBarResult.setMax(totalQuestion);
progressBarResult.setProgress(correctAnswer);
db.insertScore(Score, Name);
}
}
protected void showInputDialog() {
// get prompts.xml view
LayoutInflater layoutInflater = LayoutInflater.from(Done.this);
View promptView = layoutInflater.inflate(R.layout.dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Done.this);
alertDialogBuilder.setView(promptView);
final EditText editText = (EditText) promptView.findViewById(R.id.edittext);
// setup a dialog window
alertDialogBuilder.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String Name = editText.getText().toString();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}

try this
protected void showInputDialog() {
// get prompts.xml view
LayoutInflater layoutInflater = LayoutInflater.from(Done.this);
View promptView = layoutInflater.inflate(R.layout.dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Done.this);
alertDialogBuilder.setView(promptView);
final EditText editText = (EditText) promptView.findViewById(R.id.edittext);
// setup a dialog window
alertDialogBuilder.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String Name = editText.getText().toString();
//call a function which do in background and have a connection with database
new setname(Name);
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}
private void setname(final String name){
#Override
protected String doInBackground(String... params){
Data = new HashMap<String, String>();
Data.put("name", name);
try {
JSONObject json = Connection.UrlConnection("http://url", Data);
int succ = json.getInt("success");
if (succ == 0) {
s = "false";
} else {
s = "true";
}
} catch (Exception e) {
}
return s;
}
}
}
Also write a php file which code insert to db

Make the Name variable global and don't use the following line :
String Name;
Bundle extra = getIntent().getExtras();
if (extra != null)
{
showInputDialog();
final int Score = extra.getInt("SCORE");
final int totalQuestion = extra.getInt("TOTAL");
int correctAnswer = extra.getInt("CORRECT");
txtTotalScore.setText(String.format("SCORE : %d", Score));
txtTotalQuestion.setText(String.format("PASSED : %d/%d", correctAnswer, totalQuestion));
progressBarResult.setMax(totalQuestion);
progressBarResult.setProgress(correctAnswer);
db.insertScore(Score, Name);
}
}
protected void showInputDialog() {
// get prompts.xml view
LayoutInflater layoutInflater = LayoutInflater.from(Done.this);
View promptView = layoutInflater.inflate(R.layout.dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Done.this);
alertDialogBuilder.setView(promptView);
final EditText editText = (EditText) promptView.findViewById(R.id.edittext);
// setup a dialog window
alertDialogBuilder.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Name = editText.getText().toString();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}

How to get selected value from alert dialog?

I'm using alert dialog to show some records.those records are comming from db and display in Alertdialog.when user click on item i want to get item name to Log.this is my code.it show item as [test] but i want it showing as test
ArrayList arrayList and String [] categoryStrings initialized on top
List<Video> vd=Video.findWithQuery(Video.class, "select * from Video");
if (vd.size()>0) {
for (Video v : vd) {
arrayList.add(v.getTitle());
}
final List<String> list = Arrays.asList(arrayList.toString());
categoryStrings=new String[list.size()];
categoryStrings=list.toArray(categoryStrings);
AlertDialog.Builder alert = new AlertDialog.Builder(Editmedia.this);
alert.setTitle("Media List");
alert.setCancelable(false);
final int selected = 0; // or whatever you want
alert.setSingleChoiceItems(categoryStrings, selected, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
//onclick
String categoryString = categoryStrings[item];
Log.d("sel", " " + item+" "+categoryString);
edit();
}
});
alert.show();
log value showing
0 [test] i want it as test
Log

Try this, it should help
String categoryString = categoryStrings[item];
categoryString = categoryString.replaceAll("[\\p{Ps}\\p{Pe}]","");
Log.d("sel", " " +" "+categoryString);
[EDIT]
String categoryString = categoryStrings[item];
categoryString = categoryString.replace("[","");
categoryString = categoryString.replace("]","");
Log.d("sel", " " +" "+categoryString);

Try this:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Media List");
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1);
arrayAdapter.clear();
for (int i = 0; i < list.size(); i++) {
Log.i(LOG_TAG, list.get(i));
arrayAdapter.add(list.get(i));
}
builder.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getApplicationContext(), list.get(which),
Toast.LENGTH_LONG).show();
}
});
builder.setPositiveButton("Cancel",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show();

how to update listview in Popup window in Android

I have one TextView with title All Post.I'm displaying the popup window click on TextView and populate list view with two items in popup window.And trying to implement this - whenever click on list view item that item will be display in TextView and previous TextView title All Post will be add in listview in the place of clickable item.But my listview is not update on dismiss the popup window.
Here is my code of popup window.
String[] values = new String[] { "All Post", "My Post", "R-Post"};
ArrayList<String> filter_PostType = new ArrayList<String>();
str_LastSelectionValue = sharedPreferences.getString("filter_post_title", "");
if(str_LastSelectionValue.equals("NoVal"))
{
editor.putString("filter_post_title","All Post");
editor.commit();
}
else
{
str_LastSelectionValue = sharedPreferences.getString("filter_post_title", "");
}
textSearch.setText(str_LastSelectionValue);
Log.e("", " textSearch.getText().toString().trim() = " +
textSearch.getText().toString().trim());
textSearch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
popup_searchview = new PopupWindow(CustomActionActivity.this);
View layout = getLayoutInflater().inflate(R.layout.allpostsearch_popup, null);
popup_searchview.setContentView(layout);
popup_searchview.setHeight(220);
popup_searchview.setWidth(250);
popup_searchview.setOutsideTouchable(true);
popup_searchview.setFocusable(true);
popup_searchview.setBackgroundDrawable(new BitmapDrawable());
popup_searchview.showAsDropDown(v);
filter_list = (ListView) layout.findViewById(R.id.filter_ListView);
arr = new ArrayList<String>(Arrays.asList(values));
filter_PostType.clear();
for (int i = 0; i < arr.size(); i++) {
String str_PostType = arr.get(i);
if (!str_PostType.equals(str_LastSelectionValue)) {
filter_PostType.add(str_PostType);
}
}
filterPost_adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.filter_popup_list_item, R.id.text_filter_title, filter_PostType);
filter_list.setAdapter(filterPost_adapter);
filter_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String selectedFromList = (filter_list.getItemAtPosition(position).toString());
editor.putString("filter_post_title", selectedFromList);
editor.commit();
textSearch.setText(selectedFromList);
popup_searchview.dismiss();
removeItemFromList(position);
filterPost_adapter.notifyDataSetChanged();
arr = new ArrayList<String>(Arrays.asList(values));
filter_PostType.clear();
for (int i = 0; i < arr.size(); i++)
{
String str_PostType = arr.get(i);
if (!str_PostType.equals(textSearch.getText().toString().trim()))
{
filter_PostType.add(str_PostType);
int filterSize = filter_PostType.size();
Log.e(" UnMatched ", " In ListItem Click filterSize = " + filterSize);
}
}
filterPost_adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.filter_popup_list_item, R.id.text_filter_title, filter_PostType);
filter_list.setAdapter(filterPost_adapter);
}
});
}
});

Use something like this:
String[] values = new String[] { "All Post", "My Post", "R-Post"};
ArrayList<String> filter_PostType = new ArrayList<String>();
str_LastSelectionValue = sharedPreferences.getString("filter_post_title", "NoVal");
if(str_LastSelectionValue.equals("NoVal"))
{
editor.putString("filter_post_title","All Post");
editor.commit();
}
else
{
str_LastSelectionValue = sharedPreferences.getString("filter_post_title", "");
}
textSearch.setText(str_LastSelectionValue);
Log.e("", " textSearch.getText().toString().trim() = " +
textSearch.getText().toString().trim());
textSearch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
str_LastSelectionValue = sharedPreferences.getString("filter_post_title", "");
popup_searchview = new PopupWindow(CustomActionActivity.this);
View layout = getLayoutInflater().inflate(R.layout.allpostsearch_popup, null);
popup_searchview.setContentView(layout);
popup_searchview.setHeight(220);
popup_searchview.setWidth(250);
popup_searchview.setOutsideTouchable(true);
popup_searchview.setFocusable(true);
popup_searchview.setBackgroundDrawable(new BitmapDrawable());
popup_searchview.showAsDropDown(v);
filter_list = (ListView) layout.findViewById(R.id.filter_ListView);
if(!filter_PostType.isEmpty())
filter_PostType.clear();
for (int i = 0; i < values.length; i++) {
if (!values[i].equals(str_LastSelectionValue)) {
filter_PostType.add(values[i]);
}
}
filterPost_adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.filter_popup_list_item, R.id.text_filter_title, filter_PostType);
filter_list.setAdapter(filterPost_adapter);
filter_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String selectedFromList = (filter_list.getItemAtPosition(position).toString());
editor.putString("filter_post_title", selectedFromList);
editor.commit();
str_LastSelectionValue=selectedFromList;
textSearch.setText(selectedFromList);
popup_searchview.dismiss();
}
});
}
});
}
You don't need to change your adapter after user selects something because the next time user clicks the textview, you are making a new popup window with a new adapter.
If there is anything you don't understand, leave a comment.
Hope this helps :)

Custom List item change background in Android

Hi I am using custom listview and my list item contains checkbox. When updating the listview with the existing values the background is changed, so it is working fine.But when i clicks the check button, at that time the background will not changing after loading some where again then the background is changed . My question is at the time of check the item the background need to change immediately.
This is my adapter class.
public class GuestListAdapter extends BaseAdapter implements OnClickListener {

I just want to change the background of the checked item immediatly without updating the list again.

I think you need to tell the BaseAdapter to refresh the data when your OnCheckedChanged Listener is called.
GuestListAdapter.this.notifyDataSetChanged()
