In my app one video is playing after some second one alert dialog show the dialog contain question and answer student read the question and select the answer until my thread want to wait. Here i successfully get the video timing. I want to do pause the thread until alert dialog close.
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
running = true;
final int duration = mVideoView.getDuration();
new Thread(new Runnable() {
boolean myRunning;
public void run() {
synchronized (mSync) {
myRunning = mSync.running;
}
do {
textView.post(new Runnable() {
public void run() {
int time = Math.round(mVideoView.getCurrentPosition() / 1000);
textView.setText(time + "");
if (time == 5) {
running = false;
mVideoView.pause();
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Page02.this);
alertDialogBuilder.setMessage("Are you sure,You wanted to make decision");
alertDialogBuilder.setPositiveButton("yes",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface arg0, int arg1) {
onResume();
mVideoView.start();
arg0.dismiss();
}
});
alertDialogBuilder.setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}
}
});
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
if (!running) break;
}
while (mVideoView.getCurrentPosition() < duration);
}
}).start();
}
});
}
#Override
protected void onPause() {
super.onPause();
synchronized (mSync) {
running = false;// you can not set it here because
// it is possible for the thread to read it and exit the loop before he posts your message
mSync.mustBePost = true;
mSync.message = "Main Activity is going to pause";
}
}
#Override
protected void onResume() {
super.onResume();
threadNameCounter++;
synchronized (mSync) {
running = true;

Firebase Invalid Email Error in Android

I am always getting an error while trying to register a user to firebase in my android app.
"The email specified is invalid"
I noticed this happens on JellyBean devices and I don't know what the problem is, whether it is from the API or something else.
My code snippet is given below:
private void registerUser() {
// Sign Up
mRef.createUser(mAccount.name, mPassword, new Firebase.ResultHandler() {
#Override
public void onSuccess() {
loginUser(true);
}
#Override
public void onError(FirebaseError firebaseError) {
// Sign Up failed
if (firebaseError.getCode() == FirebaseError.NETWORK_ERROR) {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setMessage(R.string.connection_error_message)
.setTitle(R.string.error_title)
.setPositiveButton("Try again", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
checkUserExistence();
}
}).setCancelable(false);
AlertDialog dialog = builder.create();
dialog.show();
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setMessage(firebaseError.getMessage())
.setTitle(R.string.error_title)
.setPositiveButton("Try again", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
registerUser();
}
}).setCancelable(false);
AlertDialog dialog = builder.create();
dialog.show();
}
}
});
}

alert dialog box having list of item

In my android application, when i click on text view, i want to display an alert dialog box which contain list of items. How is it possible. kindly guide.
i code it as:
cus_name_txt = (TextView)findViewById(R.id.cus_name_txta);
cus_name_txt.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Onclick_click1(cus_name_txt);
// TODO Auto-generated method stub
}
});
contact_no_txt = (TextView)findViewById(R.id.contact_no_txta);
attend_by_txtbx = (EditText)findViewById(R.id.attend_by_txt);
attend_by_txtbx.setText(My_Task.attend_by_txt);
ticket_no_txt = (TextView)findViewById(R.id.ticket_no_txta);
task_detail_txt = (TextView)findViewById(R.id.task_detail_txt);
How can i get the alert box of list of items by clicking on textView. Please guide. I'll be thankful to u

If you want to show the progressBar Before loading of the List in alert dialog, then use AsyncTask for that.
e.g.:
private class LoadingTask extends AsyncTask<String, Void, String> {
#Override
protected void onPreExecute(){
super.onPreExecute();
progressDialog.show();
}
#Override
protected String doInBackground(String... str) {
String response = "";
// Call Web Service here and return response
response = API.getDealsByCategory(str[0], str[1]);
// e.g.: above is my WebService Function which returns response in string
return response;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
System.out.println("result is: "+result);
new Thread(new Runnable() {
#Override
public void run() {
progressDialog.dismiss();
}
}).start();
// SHOW THE ALERT DIALOG HERE.....
}
}
Call AsyncTask as like below :
LoadingTask task = new LoadingTask();
task.execute("YOUR_PARAMETER","YOUR_PARAMETER");
//==============================
Just put below code in the Post Excution of the AsyncTask and you will get what you want.
final CharSequence[] items = {"","50","100","150","200","250","300","350","400","450","500","550","600","650","700","750","800","850","900","1000"};
AlertDialog.Builder builder = new AlertDialog.Builder(getParent());
builder.setTitle("Select Country");
//builder.setI
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
//Toast.makeText(getApplicationContext(), con.get(item).getCountrName(), Toast.LENGTH_SHORT).show();
selectDistanceTV.setText(items[item]);
System.out.println("Item is: "+items[item]);
/*CONTRY_ID = con.get(item).getCountryId();
stateET.requestFocus();*/
}
});
AlertDialog alert = builder.create();
alert.show();
Hope it will help you.
If you need more help on how to use AsyncTask then see here:Vogella
Comment me for any query.
Enjoy Coding... :)

Put following code in onClick of textView:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select Color Mode");
ListView modeList = new ListView(this);
String[] stringArray = new String[] { "Bright Mode", "Normal Mode" };
ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, stringArray);
modeList.setAdapter(modeAdapter);
builder.setView(modeList);
final Dialog dialog = builder.create();
dialog.show();
Or
Dialog dialog = new Dialog(**Your Context**);
dialog.setContentView(R.layout.**Your Layout File**);
dialog.show();
In this layout file you can make your layout as per your requirements. When you want to use ListView from your Dialog Layout file then you have to write
ListView listView = (ListView)**dialog**.findViewById(R.id.**Your ListView Id**)

You can pass list of items in an String Array and display it in AlertBox..
For Example:
private void SingleChoice() {
String[] selectFruit = new String[] {"Apple","orange","mango"};
Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Single your Choice");
builder.setItems(selectFruit, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this,
selectFruit[which] + " Selected", Toast.LENGTH_LONG)
.show();
dialog.dismiss();
}
});
builder.setNegativeButton("cancel",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show();
}

button.setOnClickListener(new OnClickListener()
{
public void onClick(View arg0)
{
new AlertDialog.Builder(MainActivity.this)
.setSingleChoiceItems(arrClientName,0, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
name.setText(arrClientName[which]);
}
})
.setPositiveButton("Ok", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int id)
{
}
})
.show();
}
});

Application alarm causing a weird error until I press the back button

I have an alarm in my application that notifies me every 10 minutes. It works fine but each time when the alarm notifies me, my application name will show as a box in the middle of the screen, and I can't press anything until I press the back button. It's really weird!
Here is my code:
// Alert Code
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Confirmation");
alertDialog.setMessage("Are you sure you want to send this report?");
run(gotDataS);
// Timer Code
pendingIntent = PendingIntent.getService(CreateNewForm_3.this, 0,
new Intent(NewForm_3.this, MyAlarmService.class), 0);
Send.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
alertDialog.setButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
Toast.makeText(NewForm_3.this, "Sent", 0)
.show();
long firstTime = SystemClock.elapsedRealtime();
am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
firstTime + 10 * 1000, 30 * 1000, pendingIntent);
// firstTime Will be the current_time + ( 10 * 60 * 1000) =)
// 10* 1000 will be (10 * 60 * 1000)
new Handler().postDelayed(new Runnable() {
public void run() {
bCancel.performClick();
}
}, (30 * 1000));
// ( 30 * 1000) will be firstTime + ( 2- duration)
Intent toRecentCases = new Intent(CreateNewForm_3.this,
LMPActivity.class);
startActivity(toRecentCases);
}
});
alertDialog.setButton2("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
// Here you can add functions
}
});
alertDialog.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog.show();
}
});
bCancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
am.cancel(pendingIntent);
}
});
//For Notification -3-
final AlertDialog alertDialog3 = new AlertDialog.Builder(this).create();
alertDialog3.setTitle("Confirmation");
alertDialog3.setMessage("Are you sure you want to quite?");
// Press cancel button it will move user to actvity p
Cancelb.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
alertDialog3.setButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
Intent toRecentCases = new Intent(NewForm_3.this,
LMPActivity.class);
startActivity(toRecentCases);
}
});
alertDialog3.setButton2("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
// Doing nothing!
}
});
alertDialog3.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog3.show();
}
});
}
This is Showing Dialog Activity
public class ShowingDialog extends Activity {
boolean b;
String CancelMsg;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
//For Notification -1-
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Confirmation");
alertDialog.setMessage("Do you really want it?");
// For Notification -2-
final AlertDialog alertDialog2 = new AlertDialog.Builder(this).create();
alertDialog2.setTitle("Confirmation");
alertDialog2.setMessage("Are you sure you want it?");
alertDialog.setButton("yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent intent= new Intent(ShowingDialog.this,MyPage.class);
startActivity(intent);
;
}
});
alertDialog.setButton2("no",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
alertDialog2.setButton("yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Here you can add functions
// Sending a Message to server that the plaintiff found the case
// For Sending SMS with cancel Request
// Getting Case_ID + putting it inside CancelMsg
CancelMsg = "Case_ID cancel";
if (!b) {
try {
sendSMS("5556", CancelMsg);
Toast.makeText(ShowingDialog.this, "Sent", Toast.LENGTH_LONG)
.show();
} catch (Exception e) {
// TODO Auto-generated catch block
Toast.makeText(ShowingDialog.this, e.getMessage(),
Toast.LENGTH_LONG).show();
}
}
}
});
alertDialog2.setButton2("no", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Here you can add functions
// Do nothing
}
});
alertDialog2.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog2.show();
}
});
alertDialog.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog.show();
}
public void sendSMS(String number, String msg) throws Exception {
if (!b) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(number, null, msg, null, null);
}
b = true;
}
}
In Manifest :
<activity
android:name=".ShowingDialog"
android:theme="#android:style/Theme.Dialog" />

It doesn't appear that you're overloading the back statement, so when you hit the back button you're traveling back up your Back Stack. The Android documentation has more information on this:
Tasks and Back Stack

Adding a Cancel Button to a CustomAlertDialog

I am just a themer, not a programmer, any help/guidance is appreciated.
I am trying to add a Cancel button to this code:
public class gobuuf extends Activity {
/** Called when the activity is first created. */
class CustomAlertDialog extends AlertDialog {
public CustomAlertDialog(Context context) {
super(context);
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
boolean ret = super.onKeyDown(keyCode, event);
finish();
return ret;
}
public void setCancel(int buttonNegative, String string, Object object) {
// TODO Auto-generated method stub
}
}
private CustomAlertDialog mDialog;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if (isExistSkin("com.gau.go.launcherex")) {
startGOLauncher("com.gau.go.launcherex");
finish();
return;
}
mDialog = new CustomAlertDialog(this);
mDialog.setTitle(R.string.dialogtitle);
mDialog.setMessage(getResources().getString(R.string.dialogcontent));
mDialog.setCancel(DialogInterface.BUTTON_NEGATIVE, getResources().getString(R.string.dialognothanks), null);
mDialog.setButton(DialogInterface.BUTTON_POSITIVE, getResources().getString(R.string.dialogok),
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
String marketuriString = "market://search?q=pname:com.gau.go.launcherex";
Intent EMarketintent = new Intent(Intent.ACTION_VIEW, Uri.parse(marketuriString));
EMarketintent.setPackage("com.android.vending");
EMarketintent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(marketuriString));
try {
startActivity(EMarketintent);
} catch (ActivityNotFoundException e) {
String link = "http://61.145.124.93/soft/3GHeart/com.gau.go.launcherex.apk";
Uri browserUri = Uri.parse(link);
Intent browserIntent = new Intent(Intent.ACTION_VIEW, browserUri);
browserIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
startActivity(browserIntent);
} catch (ActivityNotFoundException e2) {
// TODO: handle exception
e2.printStackTrace();
}
} catch (Exception e3) {
// TODO: handle exception
e3.printStackTrace();
}
finish();
}
});
mDialog.show();
}
#Override
protected void onDestroy() {
super.onDestroy();
android.os.Process.killProcess(android.os.Process.myPid());
}
private boolean isExistSkin(String packageName) {
try {
createPackageContext(packageName,
Context.CONTEXT_IGNORE_SECURITY);
} catch (NameNotFoundException e) {
return false;
}
return true;
}
private void startGOLauncher(String packageName){
PackageManager packageMgr = this.getPackageManager();
Intent launchIntent = packageMgr.getLaunchIntentForPackage(packageName);
if (null != launchIntent){
try
{
this.startActivity(launchIntent);
}
catch(ActivityNotFoundException e)
{
}
}
}
}
I have added the corresponding string, but don't know what else to do: add an onclicklistener, I know I need some kind of action coded somewhere finish(); or .cancel something. Thanks for any help, again.
I should say, I've been playing around with this bit you see:
mDialog.setCancel(DialogInterface.BUTTON_NEGATIVE,getResources().getString(R.string.dialognothanks), null);

I am not sure if this is exactly what you are looking for, but you can do something like this... this one just closes the dialog.
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
For a very good tutorial on creating dialogs, I would recommend using : http://developer.android.com/guide/topics/ui/dialogs.html. This should be very helpful.

It's now working and performing how I wanted it to by doing this:
1) I removed:
public void setCancel(int buttonNegative, String string, Object object) {
// TODO Auto-generated method stub
}
and
mDialog.setCancel(DialogInterface.BUTTON_NEGATIVE, getResources().getString(R.string.dialognothanks), null);
2) and added:
mDialog.setButton(DialogInterface.BUTTON_NEGATIVE, getResources().getString(R.string.dialognothanks),
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
mDialog.cancel();
finish();
}
});
just before the
mDialog.show();
Trial and Error FTW. Maybe I should learn Java and Android from the ground up to save me the time later.
Now I have to learn how to make the Cancel button not only finish(); but also start another activity.

I figured out how to start an activity by following the answer on this page:
Android: How to start an Activity from an alert dialog
So my code now looks like:
mDialog.setButton(DialogInterface.BUTTON_NEGATIVE, getResources().getString(R.string.dialognothanks),
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Intent i = new Intent(getBaseContext(), AboutActivityOverview.class);
startActivity(i);
}
});
