Show DialogBox in loop in android - android

I am trying to show dialog boxes with contents from the database .The fetched data from the database may contain more than 1 data.So I have to show dialog in for loop.But the dialog shows only for the first row in the database.Here is the code
cursor = sqldb.query(Database_Handler.dbdectab, null,"((" + Database_Handler.gendtime + "<='" + after_1hr + "' and " + Database_Handler.gendtime + ">='" + before_1hr + "') and ("
+ Database_Handler.calused + "='Gregorian' or " + Database_Handler.calused + "='both')) ", null, null, null, null);
notif_count = cursor.getCount();
//dec_name_ctr_builder = new StringBuilder("");
if(notif_count>0)
{
dialog1 = new Dialog(this);
cursor.moveToFirst();
do
{
dec_name =cursor.getString(cursor.getColumnIndex(Database_Handler.decname));
dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog1.setContentView(R.layout.custom_dialog_alert);
TextView tv_alert = (TextView)dialog1.findViewById(R.id.txt_alert);
tv_alert.setText( dec_name );
Button yes = (Button) dialog1.findViewById(R.id.btn_yes);
Button no = (Button) dialog1.findViewById(R.id.btn_no);
yes.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(donateurl));
startActivity(intent);
dialog1.dismiss();
cursor.close();
sqldb.close();
finish();
}
});
no.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
dialog1.dismiss();
cursor.close();
sqldb.close();
finish();
}
});
dialog1.show();
}while(cursor.moveToNext());


Android dialog boxes are not modal (which is to say, they don't block the background processes).Hence your work is done asycnhronuosly and according to :
Romain guy
We've designed Android to prevent developers from writing synchronous dialogs so you don't really have much of a choice.
SO you can not block the while loop execution in between using Dialog.


Karan_Rana is right. The simplest solution for your answer would be storing the results somewhere else and displaying a new dialog each time some data is left and user clicks on a previous dialogs button.


I know this is a bit late, but I had a similar problem once. I used recursion to loop a dialog box. My situation was unique as I needed to detect an internet connection during app startup. So, this approach may not work for you. But I was able to implement the solution without for loops and blocking the main UI thread. Because I was on a splash screen, there was no other UI I needed to contend so I would simple call the dialog box again until the user chooses to "Quit".
I had a splash screen that would only continue to the landing activity of the app if a network connection was detected.
Sample code below to demonstrate the concept. Note that there are custom methods, but you should get the idea to call the prompt again from within onClick method.
protected void onCreate(Bundle savedInstanceState) {
if (isNetworkAvailable()) {
launchApp();
} else {
retryPrompt();
}
}
private void retryPrompt() {
if (isNetworkAvailable()) {
launchApp();
} else {
final ConfirmDialog dialog = new ConfirmDialog.CustomAlertBuilder(this,
"Internet Connection",
"Internet Connection not detected. Please check your connection.",
"Retry").
setNegBtnLabel("Quit").
setCustomCallback(new CustomDialogCallback() {
#Override
public void onClickPositiveBtn(DialogInterface dialogInterface, int which) {
// go around again.
retryPrompt(); // <<== Call method recursively
}
#Override
public void onClickNegativeBtn(DialogInterface dialogInterface, int which) {
// abort app.
finish();
}
}).build();
dialog.show();
}
}

How do i get android to wait for text input?

checkbutton.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View v){
questionbox.setText("What is 2 + 2");
if(answerbox.getText().equals("4")){
questionbox.setText("good job");
}
else {
questionbox.setText("nope");
}
}
);
*Every time I run the program it automatically checks without waiting on user input, how would I be able to make it wait/allow the user to input some text before testing the user input *

Move questionbox.setText("What is 2 + 2"); to outside of checkbox setOnClickListener
questionbox.setText("What is 2 + 2");
checkbutton.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View v){
if(answerbox.getText().equals("4")){
questionbox.setText("good job");
}
else {
questionbox.setText("nope");
}
}
);
Then when you run the app first user can see the question content
After that, user can enter the answer
Then user tap on check button and you will test the result

Add a value to a list everytime the user answers correctly

I have a code written where a user has to answer a question true or false. What I want to do is everytime when a user answers correctly I add +1 to my arraylist. And then at the end of the game I display the number of answered questions. I tried to do it my way, however I get an error.
Here is how I create my list:
final ArrayList<Integer> points = new ArrayList<Integer>();
This is the button if the user presses True(For better understanding: When a user presses true a pop up window opens with the answer correct or false and the correct answer of the question. When the user clicks on the closepopup button an if method runs and checks if he pressed the right button and if its not the last question. If not, it shows the next question and adds the +1 to the list):
mYes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
initiatePopupWindow();
if(type.get(count[0])){
((TextView)pwindo.getContentView().findViewById(R.id.popupTekstasTiesaArNe)).setText("Correct!");
} else {
((TextView)pwindo.getContentView().findViewById(R.id.popupTekstasTiesaArNe)).setText("False!");
}
//Show the first answer on first button click.
((TextView)pwindo.getContentView().findViewById(R.id.popupTekstas)).setText(questions.get((count[0]) % questions.size()).answer);
// When PopUp button closes open the next question with the if/else conditions.
btnClosePopup.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//if the question is true show next question/ else close app
if (type.get(count[0])) {
points.add(1); // if the answer is correct add +1 to the list.
if(questions.size()-1 == count[0]) // if you count[0] is init to 0
{
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("WInner");
builder.setMessage("You won, play again?");
builder.setCancelable(false);
builder.setPositiveButton(android.R.string.yes,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// just close dialog
dialog.cancel();
}
});
builder.setNegativeButton(android.R.string.no,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
finish();
mResult.setText(points.size());// here I try to print the number of answered questions.
}
});
// Create dialog from builder
AlertDialog alert = builder.create();
// Show dialog
alert.show();
count[0]=0;
}
else if(questions.size()-1 < count[0])
try {
throw new Exception("Invalid ");
} catch (Exception e) {
e.printStackTrace();
}
else
count[0]++;
mQuestion.setText(questions.get(count[0]).question); // you dont need calculate the module anymore
pwindo.dismiss();
} else {
count[0]++;
mQuestion.setText(questions.get(count[0]).question); // you dont need calculate the module anymore
pwindo.dismiss();
}
}
});
}
});
EDITED!!!
I figured out why SetText shows a blank textview. I want to show the answered question count in activity before the questions. I have a menuActivity>LevelselectActivity>GameActivity. In game activity I add to the list values. How to post them in LevelselectActivity? Should I use shared preferences? I have no idea now..

How to transfer parameters value from dialog box to activity in android?

I have an activity (Main) and I inserted a button in it.
When button the user press it, a dialog box with 2 Radio boxes appear. I want to set "1" or "0" value to "ntv", based on which radiobutton is selected, and then use "ntv" value in Main activity, but it seems that this doesnot transfer "ntv" value to Main activity, what is wrong with my code?
final CharSequence[] chan = {"Minutes", "Seconds"};
builder = new AlertDialog.Builder(Main.this);
builder.setTitle("Please Select:");
builder.setSingleChoiceItems(chan, 0, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if(chan[item]=="Minutes")
{
Toast.makeText(getApplicationContext(), "Minutes", Toast.LENGTH_SHORT).show();
ntv="1";
}
else if (chan[item]=="Seconds")
{
Toast.makeText(getApplicationContext(), "Seconds", Toast.LENGTH_SHORT).show();
ntv="0";
}
}
});
AlertDialog alert = builder.create();
alert.show();
I defined "ntv" as string and this is part of code when "ntv" is compared to check if it is "0" or "1"
ImageView set1= (ImageView) findViewById(R.id.set1);
ImageView set2= (ImageView) findViewById(R.id.set2);
if (ntv.equals("0")) {
set1.setVisibility(View.INVISIBLE);
}
if (ntv.equals("1")) {
set2.setVisibility(View.INVISIBLE);
}
and because neither (set1) nor (set2) doesnot go invisible I realize that "ntv" have no value.

This all looks OK (except the suggestion to use equals() instead of == for the string compares, although, as you say, it does work (it just isn't good practice).
The only thing I can think of (without seeing all the code) is that the scope of variable ntv is wrong. Have you declared the variable inside a method? It needs to be defined as an instance variable in your class (ie: not within a method).

you should be doing .equals on the string comparison NOT ==
It is unlikely that your if statements will trigger because of this.
if(chan[item].equals("Minutes"))
{
Toast.makeText(getApplicationContext(), "Minutes", Toast.LENGTH_SHORT).show();
ntv="1";
}
else if (chan[item].equals("Seconds"))
{
Toast.makeText(getApplicationContext(), "Seconds", Toast.LENGTH_SHORT).show();
ntv="0";
}

it's not clear the complete code you use and how you call the code that change visibility. Below an example
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AlertDialog.Builder builder;
final CharSequence[] chan = {"Minutes", "Seconds"};
builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Please Select:");
builder.setSingleChoiceItems(chan, 0, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if(chan[item].equals("Minutes")) {
showToast("Minutes");
} else if (chan[item].equals("Seconds")) {
showToast("Seconds");
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
private void showToast(String s){
Toast.makeText(getApplicationContext(), s, Toast.LENGTH_SHORT).show();
}
instead of showToast function you can use a your function to change visibility

Improve this question
Is there a best practice approach to prompt Android users to rate your application? Considering they could acquire it from Amazon.com or Google Marketplace what is the best route to handle this in a way that allows users to vote?

For Google Marketplace, take a look at this neat code snippet. I'm sure you can modify it to launch the Amazon Appstore instead or in addition to.
EDIT: Looks like the site changed their URL structure so I've updated the link above so it works now. Here is an old copy at the Wayback Machine in case their site goes down again. I will paste the main contents of the post below as an additional backup but you still might want to visit the link to read the comments and get any updates.
This code prompts engaged users to rate your app in the Android market (inspired by iOS Appirater). It requires a certain number of launches of the app and days since the installation before the rating dialog appears.
Adjust APP_TITLE and APP_PNAME to your needs. You should also tweak DAYS_UNTIL_PROMPT and LAUNCHES_UNTIL_PROMPT.
To test it and to tweak the dialog appearance, you can call AppRater.showRateDialog(this, null) from your Activity. Normal use is to invoke AppRater.app_launched(this) each time your activity is invoked (eg. from within the onCreate method). If all conditions are met, the dialog appears.
public class AppRater {
private final static String APP_TITLE = "YOUR-APP-NAME";
private final static String APP_PNAME = "YOUR-PACKAGE-NAME";
private final static int DAYS_UNTIL_PROMPT = 3;
private final static int LAUNCHES_UNTIL_PROMPT = 7;
public static void app_launched(Context mContext) {
SharedPreferences prefs = mContext.getSharedPreferences("apprater", 0);
if (prefs.getBoolean("dontshowagain", false)) { return ; }
SharedPreferences.Editor editor = prefs.edit();
// Increment launch counter
long launch_count = prefs.getLong("launch_count", 0) + 1;
editor.putLong("launch_count", launch_count);
// Get date of first launch
Long date_firstLaunch = prefs.getLong("date_firstlaunch", 0);
if (date_firstLaunch == 0) {
date_firstLaunch = System.currentTimeMillis();
editor.putLong("date_firstlaunch", date_firstLaunch);
}
// Wait at least n days before opening dialog
if (launch_count >= LAUNCHES_UNTIL_PROMPT) {
if (System.currentTimeMillis() >= date_firstLaunch +
(DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000)) {
showRateDialog(mContext, editor);
}
}
editor.commit();
}
public static void showRateDialog(final Context mContext, final SharedPreferences.Editor editor) {
final Dialog dialog = new Dialog(mContext);
dialog.setTitle("Rate " + APP_TITLE);
LinearLayout ll = new LinearLayout(mContext);
ll.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(mContext);
tv.setText("If you enjoy using " + APP_TITLE + ", please take a moment to rate it. Thanks for your support!");
tv.setWidth(240);
tv.setPadding(4, 0, 4, 10);
ll.addView(tv);
Button b1 = new Button(mContext);
b1.setText("Rate " + APP_TITLE);
b1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mContext.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME)));
dialog.dismiss();
}
});
ll.addView(b1);
Button b2 = new Button(mContext);
b2.setText("Remind me later");
b2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
dialog.dismiss();
}
});
ll.addView(b2);
Button b3 = new Button(mContext);
b3.setText("No, thanks");
b3.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (editor != null) {
editor.putBoolean("dontshowagain", true);
editor.commit();
}
dialog.dismiss();
}
});
ll.addView(b3);
dialog.setContentView(ll);
dialog.show();
}
}

Uri uri = Uri.parse("market://details?id=" + context.getPackageName());
Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
try {
context.startActivity(goToMarket);
} catch (ActivityNotFoundException e) {
UtilityClass.showAlertDialog(context, ERROR, "Couldn't launch the Google Playstore app", null, 0);
}

You could also use RateMeMaybe: https://github.com/Kopfgeldjaeger/RateMeMaybe
It gives you quite some options to configure (minimum of days/launches until first prompt, minimum of days/launches until each next prompt if user chooses "not now", dialog title, message etc.). It is also easy to use.
Example usage from README:
RateMeMaybe rmm = new RateMeMaybe(this);
rmm.setPromptMinimums(10, 14, 10, 30);
rmm.setDialogMessage("You really seem to like this app, "
+"since you have already used it %totalLaunchCount% times! "
+"It would be great if you took a moment to rate it.");
rmm.setDialogTitle("Rate this app");
rmm.setPositiveBtn("Yeeha!");
rmm.run();
Edit: If you want to only show the prompt manually, you can also just use the RateMeMaybeFragment
if (mActivity.getSupportFragmentManager().findFragmentByTag(
"rmmFragment") != null) {
// the dialog is already shown to the user
return;
}
RateMeMaybeFragment frag = new RateMeMaybeFragment();
frag.setData(getIcon(), getDialogTitle(), getDialogMessage(),
getPositiveBtn(), getNeutralBtn(), getNegativeBtn(), this);
frag.show(mActivity.getSupportFragmentManager(), "rmmFragment");
getIcon() can be replaced with 0 if you don't want to use one; the rest of the getX calls can be replaced with Strings
Changing the code to open the Amazon Marketplace should be easy

Maybe set up a Facebook link to a fan page with "like" options and so forth? An icon with a small label on the main menu would nicely sufficient and not as annoying, if at all, as a pop up reminder.

Just write these two lines of code under your "Rank this Apps" button and it will take you to the Google store where you have uploaded your app.
String myUrl ="https://play.google.com/store/apps/details?id=smartsilencer";
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(myUrl)));

I think, redirecting users to your app's web page is the only solution here.

Play store policy says that if we notify users to perform some action in our app, then we must also let users cancel the operation if the user doesn’t want to perform that action. So if we ask users to update the app or rate the app on the Play store with Yes(Now), then we must also give an option for No(Later, Not Now), etc.
rateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
r.showDefaultDialog();
}
});
where r is a class which contain showDefaultDialog method
public void showDefaultDialog() {
//Log.d(TAG, "Create default dialog.");
String title = "Enjoying Live Share Tips?";
String loveit = "Love it";
String likeit = "Like it";
String hateit = "Hate it";
new AlertDialog.Builder(hostActivity)
.setTitle(title)
.setIcon(R.drawable.ic_launcher)
//.setMessage(message)
.setPositiveButton(hateit, this)
.setNegativeButton(loveit, this)
.setNeutralButton(likeit, this)
.setOnCancelListener(this)
.setCancelable(true)
.create().show();
}
To download a full example[androidAone]:http://androidaone.com/11-2014/notify-users-rate-app-playstore/

for simple solution try this library
https://github.com/kobakei/Android-RateThisApp
you can also change its configuration like criteria to show dialog , title , message

In any event :eg button
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData
(Uri.parse("market://details?id="+context.getPackageName()));
startActivity(intent);

Can any body explain this code from Hello Android book

I cannot understand this code in page number 68-69 in Hello Android book. Some methods used in the code are new to me. Can anybody elaborate and explain the code.
private static final String TAG = "Sudoku" ;
private void openNewGameDialog() {
new AlertDialog.Builder(this)
.setTitle(R.string.new_game_title)
.setItems(R.array.difficulty, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialoginterface,int i) {
startGame(i);
}
})
.show();
}
private void startGame(int i) {
Log.d(TAG, "clicked on " + i);
// Start game here...
}

All it does is when you call openNewGameDialog() it will create an alertdialog with an assigned title and list of options from a resource file ("R.array.difficulty" is an integer value ultimately pointing to a string-array declared in the file /res/values/arrays.xml). An AlertDialog is a simple to create way of getting input from the user. It can also be used for output, but many prefer Toast for that task. The
.show() at the end of it brings the dialog to the foreground.
When the items are added in that call they are assigned an onClick listener which when an item is clicked it sends the index of that item to startGame. In that function it only sends a message including the index to the logcat debug system.
