This is the result I am getting. I press this dish twice and its shown only once. It should be shown twice the same dish name. Please Guide.
The code is really long to follow on here. But speaking generally, do you save each dish with different key-value pair? Maybe think about such solution. OR you could store the dishes in an array, which can be stored in Shared prefs, and once you want to see your dishes, just read out the Array List and display the items inside it.
You store the String into an Array, whenever you want to do it in your code. It's just like mArrayList.add("String"); and then you can update yuor SharedPrefs the same you already do, just check the URL on how to store ArrayList to SharedPrefs. Would be a cleaner solution in my view.
Here you can see how to store ArrayList in SharedPreferences:
Save ArrayList to SharedPreferences
And the once you want to display the items from ArrayList, you pull ArrayList from SharedPrefs and display them in AlertDialog ListView.
And here it is explained how to display Array Items in AlertDialog:
How can I display a list view in an Android Alert Dialog?
I want to change the dialog of exit app with twi choices choice 1 = "rate" and choice 2 = "exit" now i can only show exit or stay dialog but i want to convert it to what i described here is the code :
#Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setMessage("Are you sure you want to exit?")
.setCancelable(false)
.setNeutralButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
PicSelect.this.finish();
}
})
.setNegativeButton("No", null)
.show();
}
and this the class code `

for (int i= 0; i < ids.length; i++){
ids[i] = Integer.toString(i+1);
}
imageAdapter=new Itemadapter(getApplicationContext(), R.layout.photo_item,ids,"CATIMAGE");
photoGrid.setAdapter(imageAdapter);

finaly if anyone know how to style the text thank you for your help
.setNegativeButton("Rate App", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent i = new Intent(android.content.Intent.ACTION_VIEW);
i.setData(Uri.parse("market://details?id=[your package name]"));
startActivity(i);
}
})
This will give you a negative option that says Rate App that when clicked opens the market to your app.
Improve your app with this snippet in onBackPressed():
if(isTaskRoot()) {
if (this.lastBackPressTime < System.currentTimeMillis() - 2000) {
toast = Toast.makeText(this, getString(R.string.hinweisBeendeApp), Toast.LENGTH_SHORT);
toast.show();
this.lastBackPressTime = System.currentTimeMillis();
} else {
if (toast != null) {
toast.cancel();
}
super.onBackPressed();
}
}else {
super.onBackPressed();
}
Ok so I recently completed an android app - my first one :D! - and because it is a paid app Google tells me I have to add the licensing stuff. That's fine and dandy, except I've been getting mind f*cked by it for the past five hours. Finally think I understand it a little and got it going, but in testing it in my emulator I come up with two issues:
I'm using the google API for 4.1, as instructed by their handy how-to on the developer console, but nomatter what I always end up coming up with my Connection Error dialog. Code here:
public void dontAllow(int reason) {
if(isFinishing()){
return;
}
displayResults("Access Denied");
if(reason==Policy.RETRY){
showDialog(DIALOG_RETRY);
}else{
showDialog(DIALOG_ERROR);
}
}
public void applicationError(int errorCode) {
dontAllow(0);
}
public void displayResults(String result){
}
And cooresponding dialog being called:
protected Dialog onCreateDialog(int id){
switch(id){
case DIALOG_RETRY:
Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Connection Error: Retry?");
builder.setCancelable(true);
builder.setPositiveButton("Retry", new RetryOnClickListener());
builder.setNegativeButton("Cancel", new CancelOnClickListener());
AlertDialog dialog = builder.create();
dialog.show();
break;
case DIALOG_ERROR:
Builder builder1 = new AlertDialog.Builder(this);
builder1.setMessage("Would you like to purchase Landscape ID! ?");
builder1.setCancelable(true);
builder1.setPositiveButton("Yes!", new BuyOnClickListener());
builder1.setNegativeButton("No.", new CancelOnClickListener());
AlertDialog dialog1 = builder1.create();
dialog1.show();
break;
}
return super.onCreateDialog(id);
}
private final class RetryOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {
checker.checkAccess(checkerCB);
}
}
private final class CancelOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {

finish();
}
}
private final class BuyOnClickListener implements

public void onClick(DialogInterface dialog, int which) {
Intent open = new Intent(Intent.ACTION_VIEW);
open.setData(Uri.parse("market://details? id=com.mustaroenterprise.landscapeid"));
startActivity(open);
}
}
My first question: How come it isn't connecting to the server as it should be? I've constructed my testing apratus as instructed by their tutorial. I've gone over it three times!
Second question: When I do launch the app on the emulator, the Connection Error dialog shows up fine. I hit retry, and it works. I hit Cancel, and it kills the app. However, if I simply click anywhere else in the window, outside the dialog, it closes the dialog and the app works normally. That kindof defeats the whole purpose, eh? How do I make that... not so?
Just in case I'm an idiot and the error lies elsewhere, here's the whole class:

For your second question, I would set setCanceledOnTouchOutside to false like so:

builder.setPositiveButton("Retry", new RetryOnClickListener());
builder.setNegativeButton("Cancel", new CancelOnClickListener());
AlertDialog dialog = builder.create();
//Add this
dialog.setCanceledOnTouchOutside(false);
dialog.show();
I'm still new to Java and in Android programming so I'm a bit confused in some programming methods. I just want to ask, how do I use return value of method match_eye() in another class ?. I just want to use mmres.minVal and mmres.maxVal values in a another class (FdActivity) and display these values in my activity class.can anyone show me the code to do this :) thanks

As far as I understand you have Activity where you want to show two values which you want to get from another class. You can't return two values from one function that's why I suggest you to create your own Object which will hold these values and you can return your custom object from match_eye() for example and get your values from your Activity. Here is example code:
MyCustomObject.java
public MyObject{
private int mFirstValue;
private int mSecondValue;
// public constructor
public MyObject(int firstValue, int secondValue){
this.mFirstValue = firstValue;
this.mSecondValue = secondValue;
}
// first value getter
public int getFirstValue(){
return mFirstValue;
}
// second value getter;
public int getSecondValue(){
return mSecondValue;
}
}
and in your match_eye() you can do something similar to this:
public MyObject match_eye(Rect area, Mat mTemplate,int type){
//do your calculations here ...
int firstValue = 0; // get first value
int secondValue = 0; // get second value
return new MyObject(firstValue, secondValue);
}
and in your Activity you just need to call :
MyObject mCurrentObject = FdView.match_eye(/*params*/); // static call as example
if(mCurrentObject != null){
int myFirstValue = mCurrentObject.getFirstValue();
int mySecondValue = mCurrentObject.getSecondValue();
// Show these values in your Activity.
}
Take object of that class in which you defined your method into your second activity and use like below code:
testing t1 = new testing();
double returnval = t1.match_eye(yourarea, youmTemplate,yourtype);
System.out.println(returnval);
For sending value using Intent:
Intent i = new Intent(context,MainActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("var", returnval)
context.startActivity(i);
i can't seem to figure out why my app/code is crashing in this section. Any help would be appreciated. I think the problem lies on the creation of an AlertDialog in the else if statement.
Basically, this method is called on first launch of the application and asks the user to choose between two options: OCPS and Other. When OCPS is chosen, a SharedPreference is set. When other is selected, an AlertDialog with text box should pop up, allowing the user to input their own local URL, which is then saved to the SharedPreference.
Full code is available here: https://github.com/danielblakes/progressbook/
code follows:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
boolean firstrun = getSharedPreferences(
"com.danielblakes.progressbook", MODE_PRIVATE).getBoolean(
"firstrun", true);
if (firstrun) {
new AlertDialog.Builder(this).setTitle("First Run").show();
pickDistrict(this);
getSharedPreferences("com.danielblakes.progressbook", MODE_PRIVATE)
.edit().putBoolean("firstrun", false).commit();
}
else {
String saved_district = getSharedPreferences(
"com.danielblakes.progressbook", MODE_PRIVATE).getString(
"district", null);
startupWebView(saved_district);
}
}
public Dialog pickDistrict(final Context context) {
AlertDialog.Builder districtalert = new AlertDialog.Builder(context);
districtalert
.setTitle(R.string.choose_district)
.setItems(R.array.districts,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int i) {
if (i == 0) {
String district_site = "https://parentaccess.ocps.net/General/District.aspx?From=Global";
startupWebView(district_site);
getSharedPreferences(
"com.danielblakes.progressbook",
MODE_PRIVATE)
.edit()
.putString("district",
district_site).commit();
} else if (i == 1) {
AlertDialog.Builder customdistrict = new AlertDialog.Builder(context);
customdistrict
.setTitle(
R.string.custom_district_title)
.setMessage(
R.string.custom_district_message);
final EditText input = new EditText(
getParent());
customdistrict.setView(input);
customdistrict
.setPositiveButton(
"Ok",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
String custom_url = input
.getText()
.toString();
getSharedPreferences(
"com.danielblakes.progressbook",
MODE_PRIVATE)
.edit()
.putString(
"district",
custom_url)
.commit();
}
});
customdistrict
.setNegativeButton(
"Cancel",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
return;
}
}).show();
}
}
}).show();
return districtalert.create();
}
}
Change
AlertDialog.Builder customdistrict = new AlertDialog.Builder(this);
to
AlertDialog.Builder customdistrict = new AlertDialog.Builder(context);
also,
final EditText input = new EditText(getParent());
needed to be changed to
final EditText input = new EditText(context);
