Remember checkbox within a dialog

Remember checkbox within a dialog - java

I try to remember the checkbox within a dialogue but in comparison remember == false the variable remember still has not changed its value. In the loop is iterated as many times as the size of lelements_tmp before call showDialogSameFile() so neither can I use the variable remember within the loop. How can I do it? Thanks in advance.
private boolean remember = false;
// in the program
// add files to List lelements_tmp
while (i < lelements_tmp.size()) {
File fto = new File(lelements_tmp.get(i).getFile());
String to = null;
try {
to = fto.getCanonicalPath();
} catch (IOException e) {
e.printStackTrace();
}
if (fto.exists()) {
showDialogSameFile(fto, to, i);
i++;
continue;
}
thread(i);
i++;
}
private void showDialogSameFile(File f, String to, final int i) {
TextView title = null;
if (f.isDirectory())
title = this.getTitle("The directory " + to + " already exists. Do you want to replace the contents?");
else if (f.isFile())
title = this.getTitle("The file " + to + " already exists. Do you want to replace it?");
String[] item = {"Apply to all"};
AlertDialog ad = new AlertDialog.Builder(context)
.setCustomTitle(title)
.setMultiChoiceItems(item, null,
new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int indexSelected, boolean isChecked) {
if (isChecked)
remember = true;
}
})
.setPositiveButton("Aceptar",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
thread(i);
}
})
.setNegativeButton("Cancelar",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
})
.create();
if (remember == false)
ad.show();
}

I've had to refactor the code a bit, but basically with this work. It's necessary to call to the method from non-UI thread. Based on this response https://stackoverflow.com/a/11369224/5089855

Making own Alert dialogs extending AppCompatDialogFragment

I am trying to make my own Alert dialogs using "utility" class that extends AppCompatDialogFragment. But when I try to set my own messages, they didn't change, but the default ones of the class I created continue to appear.
For example in my AlertDialogConnection class I made Override of onCreateDialog, but in my activity, while I perform http request, I can't make my own texts.
My own class that extends AppCompatDialogFragment
public class AlertDialogConnection extends AppCompatDialogFragment {
private Builder builder;
private String title;
private String text;
public AlertDialogConnection(){
this.builder = null;
this.text = "";
this.title = "";
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
if((this.title == "") || (this.text == "") || (this.builder == null)){
this.builder = new Builder(getActivity());
this.builder.setTitle("Error");
this.builder.setMessage("Default Error: Error! try later");
this.builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
System.exit(0);
}
});
}else {
this.builder = new Builder(getActivity());
this.builder.setTitle(this.title);
this.builder.setMessage(this.text);
this.builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
System.exit(0);
}
});
}
return builder.create();
}
public void setTitle(String title){
this.title = title;
}
public void setText(String text){
this.text = text;
}
}
Some code using that class
in this class, in case of error I continue to see the default error of the class AlertDialogConnection, instead of my serverError title and text.
private AlertDialogConnection serverError = new AlertdialogConnection();
private void requestData(String url) throws MalformedURLException {
Request request = new Request.Builder().url(url).build();
final Intent intent = new Intent(this, ModelResultData.class);
httpClient.connectTimeoutMillis(); //server timeout
httpClient.writeTimeoutMillis();
httpClient.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
Log.d("HTTP-Error", "HTTP request error!");
AlertDialogConnection errorDialog = new AlertDialogConnection();
errorDialog.setTitle("server error!");
errorDialog.setText("server messaging error, try later");
errorDialog.show(getSupportFragmentManager(), "messaging error!");
//Toast.makeText(getApplicationContext(), "results not found", Toast.LENGTH_LONG).show();
}
#Override
public void onResponse(#NotNull Call call, Response response) throws IOException {
if(response.isSuccessful()){
/* HTTP-code: 200 */
final String body = response.body().string();
ModelSearchActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
intent.putExtra("ACTIVITY_SOURCE", "ModelSearchActivity");
intent.putExtra("json_data", body);
startActivity(intent);
}
});
}else{
//System.out.println(response.code());
//if (response.code() == 403) {
//Toast.makeText(getApplicationContext(), "results not found", Toast.LENGTH_LONG).show();
//} else if (response.code() == 500) {
/* Http-code: 500 */
Log.d("HTTP-Error", "server error!");
serverError.setTitle("server error!");
serverError.setText("server error, try later");
serverError.show(getSupportFragmentManager(), "server error!");
//}
}
}
});
}
I have tried making comparisons with response code, but nothing change.

The default value (in the constructor) you've set for builder is null.
This causes it to always get through the if condition since builder == null would return true. Try something along the following lines,
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
this.builder = new Builder(getActivity());
if(this.title.isEmpty() || this.text.isEmpty()){
this.builder.setTitle("Error");
this.builder.setMessage("Default Error: Error! try later");
this.builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
System.exit(0);
}
});
}else {
this.builder.setTitle(this.title);
this.builder.setMessage(this.text);
this.builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
System.exit(0);
}
});
}
return builder.create();
}

You don't need to have a separate utility for creating your own alert dialogue you can simply create a view and use the setView method to show that view in your app. See the snippet below
private void showDialog()
{
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
View view = getLayoutInflater().inflate(R.layout.sortdialog,null);//Replace it
alertDialogBuilder.setView(view);
alertDialog = alertDialogBuilder.create();
alertDialog.show();
}
This will allow you to create custom alert dialog boxes using the layout which you have created

How to clear app cache on exit pressed button?

I just want to clear app cache on exit when pressed, tried many answers out there but got errors and didn't work, so here is my code:
if (Config.ENABLE_EXIT_DIALOG) {
AlertDialog.Builder dialog = new AlertDialog.Builder(MainActivity.this);
dialog.setIcon(R.mipmap.ic_launcher);
dialog.setTitle(R.string.app_name);
dialog.setMessage(R.string.dialog_close_msg);
dialog.setPositiveButton(R.string.dialog_option_yes, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
MainActivity.this.finish();
}
});
dialog.setNegativeButton(R.string.dialog_option_rate_us, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
final String appName = getPackageName();
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appName)));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appName)));
}
MainActivity.this.finish();
}
});
dialog.setNeutralButton(R.string.dialog_option_more, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(getString(R.string.play_more_apps))));
MainActivity.this.finish();
}
});
dialog.show();
} else {
super.onBackPressed();
}

got solved, i think it's old way but it's working fine found it here
i actually used his question code at the end of the my mainActivity file and it worked like a charm, though i guess it's an old way but it's ok.
and here is the code
#Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
clearApplicationData();
}
public void clearApplicationData() {
File cache = getCacheDir();
File appDir = new File(cache.getParent());
if (appDir.exists()) {
String[] children = appDir.list();
for (String s : children) {
if (!s.equals("lib")) {
deleteDir(new File(appDir, s));
Log.i("EEEEEERRRRRRROOOOOOORRRR", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************");
}
}
}
}
public static boolean deleteDir(File dir) {
if (dir != null && dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children[i]));
if (!success) {
return false;
}
}
}
return dir.delete();
}

Android billing consuming items

I am trying to have an consumable item for my app.
i currently use this code:
private void BuyManager() {
mHelper.flagEndAsync();
mHelper.launchPurchaseFlow(this, "jm.admin", 1011, new IabHelper.OnIabPurchaseFinishedListener() {
#Override
public void onIabPurchaseFinished(IabResult result, Purchase info) {
AlertDialog.Builder succces = new AlertDialog.Builder(MainActivity.this);
int proccesed = 1;
try {
proccesed=mservice.consumePurchase(3,getPackageName(), "inapp:"+getPackageName()+":jm.admin");
} catch (RemoteException e) {
e.printStackTrace();
}
String succs = "nee";
if (proccesed==0){
succs = "ja";
}
succces.setMessage("We checken uw aankoop Aankoop gegevens: " + result + " Aankoop succesvol: "+succs);
succces.setPositiveButton("Oke", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
succces.show();
if (result.isSuccess()) {
AlertDialog.Builder succces2 = new AlertDialog.Builder(MainActivity.this);
succces2.setMessage("Uw aankoop is voltooid");
succces2.setPositiveButton("Oke", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
succces2.show();
}
}
});
}
but when i buy the item it not consumed at all and it haves the code 7 response (item already bought).
Whats wrong with my code?

How to use return value of a method in a another class in android

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);

Dialog only first option works

I'm trying to make a SingleChoiceItems dialog activated from a listview onItemLongCLick which has 3 options via radiobuttons 1.View Profile 2.Send Message 3.Delete Friends and from the way I have it set up,only the first option toast works on all 3 options.
How would I make it that options 2 and 3 does their actions instead of doing option 1's actions?
Here is the code to my dialog,
#Override
public Dialog onCreateDialog(int id) {
String[] items = { "View Profile", "Send Message", "Remove Friend" };
final DBAdapter db = new DBAdapter(this);
db.open();
switch (id) {
case 0:
return new AlertDialog.Builder(this)
.setIcon(R.drawable.icon)
.setTitle("Select a option")
.setSingleChoiceItems(items, id,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int which) {
int choice = 0;
// TODO Auto-generated method stub
mChoice = choice;
}
})
.setPositiveButton("OK", new OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int choice) {
// TODO Auto-generated method stub
if (mChoice == 0) {
Toast.makeText(getBaseContext(), "Test 1",
Toast.LENGTH_SHORT).show();
} else if (mChoice == 1) {
Toast.makeText(getBaseContext(), "Test2",
Toast.LENGTH_SHORT).show();
} else if (mChoice == 2) {
TextView friends = (TextView) findViewById(R.id.textview_friends);
String deletedfriend = friends.getText()
.toString();
db.DeleteFriends(deletedfriend);
Toast.makeText(getBaseContext(),
"Friend Removed", Toast.LENGTH_SHORT)
.show();
}
}
}
)
.setNegativeButton("Cancel", new OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int choice) {
}
})
.create();
}
return null;
}

Remove choice = 0;
.setSingleChoiceItems(items, id,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int which) {
mChoice = which;
}
})
