Customizing my alertbox using inflater doesn't work

I am a beginner to Android Studio. I am working on my android quiz application for our school activity. The code shown below is what i have to check if my answer in my true or false question is correct. I want to display a custom AlertBox, but it doesn't work.The app stops and goes back its previous activity. I tried to change it to the default alertbox. It works fine, but if I add inflater it doesn't work. What is wrong with my code?
public void checkAnswer(View view) {
// Get pushed button.
Button answerBtn = (Button) findViewById(view.getId());
String btnText = answerBtn.getText().toString();
TextView title = (TextView) view.findViewById(R.id.title);
ImageButton imageButton = (ImageButton)
view.findViewById(R.id.image);
TextView laman = (TextView) view.findViewById(R.id.laman);
if (btnText.equals(rightAnswer)) {
// Correct!
startService(new Intent(roxasquiz.this, tamamusic.class));
imageButton.setImageResource(R.drawable.check);
title.setText("Magaling!");
laman.setText("Tama ang iyong sagot! ");
rightAnswerCount++;
} else {
// Wrong...
startService(new Intent(roxasquiz.this, malimusic.class));
title.setText("Magsanay pa!");
laman.setText("Mali ang iyong sagot! ");
imageButton.setImageResource(R.drawable.wrong);
}
// Create Dialog.
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = getLayoutInflater();
View v = inflater.inflate(R.layout.custom_layout, (ViewGroup) view, false);
builder.setPositiveButton("OK", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
if (quizCount == QUIZ_COUNT) {
// Show Result.
Intent intent = new Intent(getApplicationContext(), roxasresult.class);
intent.putExtra("RIGHT_ANSWER_COUNT", rightAnswerCount);
startActivity(intent);
} else {
quizCount++;
showNextQuiz();
}
}
});
builder.setView(v);
builder.setCancelable(false);
builder.show();
}
Here is the code that is written before the codes above.

Why my dismiss() method not able close Customize Alert dialog

I am developing a android app where I have created Customize alert dialog. I declare Globally alert dialog and and AlertDialog.builder as follow. Now I am calling three method f1(), f2(),f3(), in button click.
btn_my_order.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
f1();
f2();
f3();
return false;
}
});
I Declared orderDialog and builde globally as follow :-
private AlertDialog orderDialog = null;
AlertDialog.Builder builder;
My f1() block is as follow :-
F1{
builder = new AlertDialog.Builder(MainScreen.this);
mContext = getApplicationContext();
/**
* by the help of inflater my ordre is showing in list view
*/
inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
orderDialogLayout = inflater.inflate(R.layout.my_order_list,(ViewGroup)findViewById(R.id.order_list_root));
orderList = (ListView) orderDialogLayout.findViewById(R.id.order_list);
ibOrderDelete = (ImageButton)orderDialogLayout.findViewById(R.id.deleteOrder);
tvPrice = (TextView) orderDialogLayout.findViewById(R.id.order_list_total);
tvTaxes = (TextView) orderDialogLayout.findViewById(R.id.order_list_taxes);
tvTotal = (TextView) orderDialogLayout.findViewById(R.id.order_list_grand_total);
Button bclose = (Button) orderDialogLayout.findViewById(R.id.close);
Button bPlaceOrder = (Button) orderDialogLayout.findViewById(R.id.my_order_placeorder);
bclose.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
orderDialog.dismiss();
System.out.println(" click on close button");
}
});
/**
* click of place order to kitchen
*/
bPlaceOrder.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
System.out.println("Place order click");
palceMyOrdertoServer();
new SendOrderFromTable().execute();
System.out.println("place order to server is called");
String msg = "Your Order is Successfully placed to Kitcken";
Message msgObject = new Message();
msgObject.what = 1;
msgObject.obj = msg;
addMenuItemHandler.sendMessage(msgObject);
orderDialog.dismiss();
}
});}
My f2() is for some Cursor work with data base
F2{
// many stuff to be here populate data from cursor and bind it with adapter
// no any issue in this mehod
}
Now finally I am calling f3()
F3{
builder.setView(orderDialogLayout);
orderDialog = builder.create();
orderDialog.show();
}
Now i am going to explain all my problem f1() method is for initialization f2() is for populate data and f3() to show customize alert dialog . Why my
orderDialog.dismiss();
is not working for me.Even though i am able to see my logcat with message
"Click on close button"
That means execution is going on dismiss() method then why customize alert dialog didn't close at click. Thanks in advance to all

You should add final in your orderDialog private variable.

Android AlertDialog wait for result in calling activity

I am trying to use an AlertDialog in my app to select the quantity of an item. The problem is that the activity that calls the AlertDialog doesn't wait for it to update the item before it adds it to the SQLite Database and change intents.
At the moment, the QuantitySelector (AlertDialog) appears, then disappears straight away and changes the MealActivity class (which is just a ListView that reads from the database) through the intent change with an update to the database with quantity 0.
I need the Activity to wait for the AlertDialog to close before it updates the database.
What would be the correct way of implementing this?
Here is some code for you:
QuantitySelector (which runs the alertdialog):
public class QuantitySelector{
protected static final int RESULT_OK = 0;
private Context _context;
private DatabaseHandler db;
private HashMap<String, Double> measures;
private Item item;
private View v;
private EditText quan;
private NumberPicker pick;
private int value;
private Quantity quantity;
/**
* Function calls the quantity selector AlertDialog
* #param _c: The application context
* #param item: The item to be added to consumption
* #return The quantity that is consumed
*/
public void select(Context _c, Item item, Quantity quantity){
this._context = _c;
this.item = item;
this.quantity = quantity;
db = new DatabaseHandler(_context);
//Get the measures to display
createData();
//Set up the custom view
LayoutInflater inflater = LayoutInflater.from(_context);
v = inflater.inflate(R.layout.quantity_selector, null);
//Set up the input fields
quan = (EditText) v.findViewById(R.id.quantityNumber);
pick = (NumberPicker) v.findViewById(R.id.numberPicker1);
//Set up the custom measures into pick
pick.setMaxValue(measures.size()-1);
pick.setDisplayedValues(measures.keySet().toArray(new String[0]));
//Start the alert dialog
runDialog();
}
public void createData(){
measures = new HashMap<String, Double>();
//Get the measurements from the database
if(item!=null){
measures.putAll(db.getMeasures(item));
}
//Add grams as the default measurement
if(!measures.keySet().contains("grams")){
//Add grams as a standard measure
measures.put("grams", 1.0);
}
}
public void runDialog(){
AlertDialog dialog = new AlertDialog.Builder(_context).setTitle("Select Quantity")
.setView(v)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Change the consumption to the new quantity
if(!quan.getText().toString().matches("")){
value = Integer.parseInt(quan.getText().toString());
//Check if conversion from other units is needed
String s[] = pick.getDisplayedValues();
String a = s[pick.getValue()];
//Convert the chosen measure back to grams
if(!a.equals("grams")){
for(String m : measures.keySet()){
if(m==a){
value = (int) (value * measures.get(m));
}
}
}
}
quantity.setQuantity(value);
dialog.dismiss();
}
})
.setNegativeButton("Cancel", null).create();
dialog.show();
}
}
The method from favouritesAdapter (which calls the alertdialog):
add.setOnClickListener(new OnClickListener(){
public void onClick(View arg0) {
QuantitySelector q = new QuantitySelector();
Quantity quan = new Quantity();
q.select(_context, db.getItem(p.getID()), quan);
db.addConsumption(p.getID(), p.getFavouriteShortName(), quan.getQuantity(), "FAVOURITE");
Intent intent = new Intent(_context,MealActivity.class);
_context.startActivity(intent);
}
});
All help is appreciated :)

Use Async task and update data in doInBackGround and in onPostExecute method Show Dialog.

The way you want to go about this is to actually start the next intent when the person presses the positive button. In short, you need to be starting your next Activity in the OnClickListener that is attached to your positive button of your AlertDialog.
public void runDialog(){
AlertDialog dialog = new AlertDialog.Builder(_context).setTitle("Select Quantity")
.setView(v)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Change the consumption to the new quantity
if(!quan.getText().toString().matches("")){
value = Integer.parseInt(quan.getText().toString());
//Check if conversion from other units is needed
String s[] = pick.getDisplayedValues();
String a = s[pick.getValue()];
//Convert the chosen measure back to grams
if(!a.equals("grams")){
for(String m : measures.keySet()){
if(m==a){
value = (int) (value * measures.get(m));
}
}
}
}
quantity.setQuantity(value);
dialog.dismiss();
//The only catch now is passing through your _context
Intent intent = new Intent(_context,MealActivity.class);
_context.startActivity(intent);
}
})
.setNegativeButton("Cancel", null).create();
dialog.show();
}

Actually your problem is you are calling the start activity for MealACtivity before destroying the alert dialogue so can update your code as follows:
Update your method which calls the alertdialogue by this code:
add.setOnClickListener(new OnClickListener(){
public void onClick(View arg0) {
QuantitySelector q = new QuantitySelector();
Quantity quan = new Quantity();
q.select(_context, db.getItem(p.getID()), quan);
db.addConsumption(p.getID(), p.getFavouriteShortName(), quan.getQuantity(), "FAVOURITE");
/* Intent intent = new Intent(_context,MealActivity.class);
_context.startActivity(intent);*/
}
});
and update your Quantity Selector class with the following :
public class QuantitySelector{
protected static final int RESULT_OK = 0;
private Context _context;
private DatabaseHandler db;
private HashMap<String, Double> measures;
private Item item;
private View v;
private EditText quan;
private NumberPicker pick;
private int value;
private Quantity quantity;
/**
* Function calls the quantity selector AlertDialog
* #param _c: The application context
* #param item: The item to be added to consumption
* #return The quantity that is consumed
*/
public void select(Context _c, Item item, Quantity quantity){
this._context = _c;
this.item = item;
this.quantity = quantity;
db = new DatabaseHandler(_context);
//Get the measures to display
createData();
//Set up the custom view
LayoutInflater inflater = LayoutInflater.from(_context);
v = inflater.inflate(R.layout.quantity_selector, null);
//Set up the input fields
quan = (EditText) v.findViewById(R.id.quantityNumber);
pick = (NumberPicker) v.findViewById(R.id.numberPicker1);
//Set up the custom measures into pick
pick.setMaxValue(measures.size()-1);
pick.setDisplayedValues(measures.keySet().toArray(new String[0]));
//Start the alert dialog
runDialog();
}
public void createData(){
measures = new HashMap<String, Double>();
//Get the measurements from the database
if(item!=null){
measures.putAll(db.getMeasures(item));
}
//Add grams as the default measurement
if(!measures.keySet().contains("grams")){
//Add grams as a standard measure
measures.put("grams", 1.0);
}
}
public void runDialog(){
AlertDialog dialog = new AlertDialog.Builder(_context).setTitle("Select Quantity")
.setView(v)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Change the consumption to the new quantity
if(!quan.getText().toString().matches("")){
value = Integer.parseInt(quan.getText().toString());
//Check if conversion from other units is needed
String s[] = pick.getDisplayedValues();
String a = s[pick.getValue()];
//Convert the chosen measure back to grams
if(!a.equals("grams")){
for(String m : measures.keySet()){
if(m==a){
value = (int) (value * measures.get(m));
}
}
}
}
quantity.setQuantity(value);
Intent intent = new Intent(_context,MealActivity.class);
_context.startActivity(intent);
dialog.dismiss();
}
})
.setNegativeButton("Cancel", null).create();
dialog.show();
}

Dismiss() not working for Customize AlertDialog

I am developing a android App which is totally based on request and response from servlet.I have populate some data in customize Alert-dialog Where i using two thing one is cross button that will delete item from list in alert-dialog and update view of alert dialog , second thing is close button that will suppose to dismiss this alert-dialog. I am showing full coding of my alert-dialog. I calling alert dialog on button click by all these method.
intiliazeOrderListDialog();
showOrderListDialog();
My decleration is as follow
public AlertDialog detailsDialog, orderDialog;
AlertDialog.Builder builder;
Now i am going to post my intiliazeOrderListDialog() block.
public void intiliazeOrderListDialog() {
builder = new AlertDialog.Builder(MainScreen.this);
mContext = getApplicationContext();
inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
orderDialogLayout = inflater.inflate(R.layout.my_order_list,(ViewGroup)findViewById(R.id.order_list_root));
orderList = (ListView) orderDialogLayout.findViewById(R.id.order_list);
ibOrderDelete = (ImageButton)orderDialogLayout.findViewById(R.id.deleteOrder);
tvPrice = (TextView) orderDialogLayout.findViewById(R.id.order_list_total);
tvTaxes = (TextView) orderDialogLayout.findViewById(R.id.order_list_taxes);
tvTotal = (TextView) orderDialogLayout.findViewById(R.id.order_list_grand_total);
Button bclose = (Button) orderDialogLayout.findViewById(R.id.close);
Button bPlaceOrder = (Button) orderDialogLayout.findViewById(R.id.my_order_placeorder);
bclose.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
orderDialog.dismiss();
System.out.println(" click on closowse");
}
});
bPlaceOrder.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
System.out.println("Place order click");
palceMyOrdertoServer();
new SendOrderFromTable().execute();
System.out.println("place order to server is called");
String msg = "Your Order is Successfully placed to Kitcken";
Message msgObject = new Message();
msgObject.what = 1;
msgObject.obj = msg;
addMenuItemHandler.sendMessage(msgObject);
orderDialog.dismiss();
}
});
}
and at last i am going to post showOrderListDialog(); block
public void showOrderListDialog() {
builder.setView(orderDialogLayout);
orderDialog = builder.create();
orderDialog.show();
}
I know i have posted too many codes but its conveniences for those who want to help me . I have a very simple problem why my
orderDialog.dismiss();
is not working for me.? Thanks in advance to all .

Finally i solve my own issue . "Self help is best help ;;".
It was issue of calling method in setOnClickListener.
I just call it,
android:clickable="true"
android:onClick="clickHandler"
if (v.getId() == R.id.myOrder) {
System.out.println("Click my Order");
System.out.println("OrderListAdapter.totalCount ="
+ OrderListAdapter.totalCount);
// select COUNT(*) from CDs;
int jcount = 0;
jcount = countjournals();
System.out.println("jcount = " + jcount);
// Count implementation at my Order
if (jcount < 1) {
alertShow();
} else {
intiliazeOrderListDialog();
showOrderListDialog();
}
// startActivity(new Intent(RestaurantHome.this,
// MyOrderList.class));
}

User input alertdialog not opening after button click in BluetoothChat

Hi I'm an android newbie and I've been stuck for a week on this. Any help would be appreciated! I've done a lot of research and can't figure out what is wrong. I've successfully run the bluetoothchat sample code on two phones and successfully communicated via bluetooth. I've also successfully written and run a standalone app that, after a button click on the main activity, opens a custom alertdialog which accepts user input, and passes the input back to the main activity. But when I write the alertdialog code into the BluetoothChat code, nothing happens when I click the button. I've tried to step through the debugger with the phone but with no luck. It doesn't seem to step to the code containing the button click. There are no errors showing. Why won't the alertdialog pop up on button click? Here's the BluetoothChat.java code I've modified :
public class BluetoothChat extends Activity implements OnClickListener{
final Context context = this;
private Button rButton;
View rScreen;
private EditText mAlertDialog;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(D) Log.e(TAG, "+++ ON CREATE +++");
// Set up the window layout
setContentView(R.layout.main);
// Get local Bluetooth adapter
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
// If the adapter is null, then Bluetooth is not supported
if (mBluetoothAdapter == null) {
Toast.makeText(this, "Bluetooth is not available", Toast.LENGTH_LONG).show();
finish();
return;
}
//components from main.xml
//When button is clicked, the alert dialog is pulled up
rButton = (Button)findViewById(R.id.buttonr);
mAlertDialog = (EditText)findViewById(R.id.edittextresultm);
//add button listener
rButton.setOnClickListener(new OnClickListener() {
//#Override
public void onClick_register(View view) {
String title = "title";
String buttonOk = "OK";
String buttonCancel = "Cancel";
String madd, name;
//get review.xml view
LayoutInflater li = LayoutInflater.from(context);
View rView = li.inflate(R.layout.review, null);
//AlertDialog dialog;
AlertDialog.Builder adRegister = new AlertDialog.Builder(context);
//set review.xml to adRegister builder
adRegister.setView(rView);
//set title
adRegister.setTitle(title);
//Set EditText views to get user input
final EditText mField = (EditText)rView.findViewById(R.id.editTextm);
final EditText nField = (EditText)rView.findViewById(R.id.editTextn);
//set dialog message
adRegister.setMessage("Message")
.setCancelable(false)
.setPositiveButton(buttonOk, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String madd = mField.getText().toString();
String name = nField.getText().toString();
//get user input and set it to result on main activity
mAlertDialog.setText(mField.getText());
}
})
.setNegativeButton(buttonCancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
//if this button is clicked, close current activity
dialog.cancel();
}
});
//Create alert dialog
AlertDialog alertDialog = adRegister.create();
//dialog= adRegister.create();
//show it
adRegister.show();
//dialog.show();
}
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
});
}
}

Write your inputDialog code in OnClick Method.
Enjoy!!
