Am new to android and i have successfully manged to show data from mysql database in a list and set an alert dialog for when an item is clicked.The Alert dialog has to take in a comment about the item clicked and send it to the mysql database but am stuck at making the connection.
Here is my code
public void showList(){
try {
JSONObject jsonObj = new JSONObject(myJSON);
peoples = jsonObj.getJSONArray(TAG_RESULTS);
for(int i=0;i<peoples.length();i++){
JSONObject c = peoples.getJSONObject(i);
String id = c.getString(TAG_ID);
String fname = c.getString(TAG_FNAME);
String lname = c.getString(TAG_LNAME);
String idnum = c.getString(TAG_IDNUM);
HashMap<String,String> persons = new HashMap<String,String>();
persons.put(TAG_ID,id);
persons.put(TAG_FNAME,fname);
persons.put(TAG_LNAME,lname);
persons.put(TAG_IDNUM,idnum);
personList.add(persons);
}
final ListAdapter adapter = new SimpleAdapter(
SearchActivity.this, personList, R.layout.list_activity,
new String[]{TAG_ID,TAG_FNAME,TAG_LNAME,TAG_IDNUM},
new int[]{R.id.id, R.id.textViewFname, R.id.textViewLname,R.id.textViewIdnum}
);
list.setAdapter(adapter);
//alert dialog
//Create onclick listener class
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
/* Alert Dialog Code Start*/
AlertDialog.Builder alert = new AlertDialog.Builder(context);
alert.setTitle("Alert id: "+TAG_IDNUM); //Set Alert dialog title here
alert.setMessage("Enter Your Comment here"); //Message here
// Set an EditText view to get user input
final EditText input = new EditText(context);
alert.setView(input);
alert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// convert the input to a string and show in a toast.
String srt = input.getEditableText().toString();
Toast.makeText(SearchActivity.this,"Commenting Added", Toast.LENGTH_LONG).show();
} // End of onClick(DialogInterface dialog, int whichButton)
}); //End of alert.setPositiveButton
alert.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
Toast.makeText(SearchActivity.this,"Commenting cancled",Toast.LENGTH_LONG).show();
dialog.cancel();
}
}); //End of alert.setNegativeButton
AlertDialog alertDialog = alert.create();
alertDialog.show();
/* Alert Dialog Code End*/
// End of onClick(View v)
}
});}
catch (JSONException e){}
}
So i managed to come up with the following but the variables am sending to the php file don't seem to be getting there.
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
/* Alert Dialog Code Start*/
AlertDialog.Builder alert = new AlertDialog.Builder(context);
final String id_number =((TextView)view.findViewById(R.id.textViewIdnum)).getText().toString();
alert.setTitle("Alert id: "+id_number); //Set Alert dialog title here
alert.setMessage("Enter Your Comment here"); //Message here
// Set an EditText view to get user input
final EditText input = new EditText(context);
alert.setView(input);
alert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// convert the input to a string and show in a toast.
String reason = input.getEditableText().toString();
Toast.makeText(SearchActivity.this,"Commenting...", Toast.LENGTH_LONG).show();
final String reason_key = input.getText().toString().trim();
//final String id_number_key = textview;
StringRequest stringRequest = new StringRequest(Request.Method.POST, Config.RESULT_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(SearchActivity.this,response,Toast.LENGTH_LONG).show();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(SearchActivity.this,error.toString(),Toast.LENGTH_LONG).show();
}
});
Map<String,String> params = new HashMap<String, String>();
params.put(TAG_IDNUM,id_number);
params.put(reason_key,reason);
RequestQueue requestQueue = Volley.newRequestQueue(SearchActivity.this);
requestQueue.add(stringRequest);
} // End of onClick(DialogInterface dialog, int whichButton)
}); //End of alert.setPositiveButton
alert.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
Toast.makeText(SearchActivity.this,"Commenting cancled",Toast.LENGTH_LONG).show();
dialog.cancel();
}
}); //End of alert.setNegativeButton
AlertDialog alertDialog = alert.create();
alertDialog.show();
/* Alert Dialog Code End*/
// End of onClick(View v)
}
});}
catch (JSONException e){}

How do I set the max of how many characters can be entered. So now the user can enter a lot in the alertdialog While it should have the max. it's not like XML. That would have been easier, any tips for this alert dialog?
private void RequestNewGroup()
{
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this, R.style.AlertDialog);
builder.setTitle("Enter Group Name ");
final EditText groupNameField = new EditText(MainActivity.this);
groupNameField.setHint("");
builder.setView(groupNameField);
builder.setPositiveButton("Create", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i)
{
String groupName = groupNameField.getText().toString();
if (TextUtils.isEmpty(groupName))
{
Toast.makeText(MainActivity.this, "Please write Group Name...", Toast.LENGTH_SHORT).show();
}
else
{
CreateNewGroup(groupName);
}
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i)
{
dialogInterface.cancel();
}
});
builder.show();
}
You need to add a InputFilter to your EditText
final EditText groupNameField = new EditText(MainActivity.this);
groupNameField.setHint("");
// ### -> max length
groupNameField.setFilters(new InputFilter[]{ new InputFilter.LengthFilter(###) });
I have a button that open a dialog for change a number. The button is in activity, and generate a new class names dialogs, for storage different dialogs.
Dialog consigna: Dialogs.class
public String consigna(){
AlertDialog.Builder alert = new AlertDialog.Builder(ctxt);
alert.setTitle("Nueva temperatura");
alert.setMessage("Agrega una nueva temperatura");
final EditText input = new EditText(ctxt);
input.setInputType(InputType.TYPE_CLASS_NUMBER);
input.setRawInputType(InputType.TYPE_CLASS_NUMBER);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
data = input.getText().toString();
}
});
alert.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Put actions for CANCEL button here, or leave in blank
}
});
alert.show();
return data;
}
on click button: MainActivity
//I need change these two values:
final public double temperatura = 200.3;
String newData;
...
public void onClick(View v) {
switch (v.getId()){
case R.id.tempConsigna:
dialog = new Dialogs(MainActivity.this);
String data = dialog.consigna();
newData = data;
break;
...//other cases...
The issue is in newData = data; I doesn't have a data, because the dialog not are closed. The dialog work in other thread,no?
How to change newData var with the dialog result? It is posible into a dialogs class?
You need a callback method implemented via an interface:
public String consigna(final OnConfirm confirm){
final String[] data = new String[1];
AlertDialog.Builder alert = new AlertDialog.Builder(activity);
alert.setTitle("Nueva temperatura");
alert.setMessage("Agrega una nueva temperatura");
final EditText input = new EditText(activity);
input.setInputType(InputType.TYPE_CLASS_NUMBER);
input.setRawInputType(InputType.TYPE_CLASS_NUMBER);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
data[0] = input.getText().toString();
confirm.onConfirm(data[0]);
}
});
alert.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Put actions for CANCEL button here, or leave in blank
}
});
alert.show();
return data[0];
}
public interface OnConfirm {
void onConfirm(String s);
}
And in your Main Activity
Dialogs dialog = new Dialogs(MainActivity.this);
dialog.consigna(new Dialogs.OnConfirm() {
#Override
public void onConfirm(String s) {
Log.d("data", s);
}
});
It will not return result as you want but after click on dialog ok button then access data variable. no need to return.
I have an Alert Dialog inside a Fragment:
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(),
com.yanay.yanay.apps.odds.R.style.AppCompatAlertDialogStyle);
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.dialog_numberpicker, null));
View view = inflater.inflate(R.layout.dialog_numberpicker, null);
final EditText editText = (EditText) view.findViewById(R.id.numberpicked);
if (editText.getText().toString() != null){
numberpicked = editText.getText().toString();
Log.d("Text Picked", numberpicked);}
Boolean reverse = true;
String title = "";
String dialogMessage = "";
String buttonTitle = "";
if (!didStart && replies == 0) {
buttonTitle = "Choose Odds";
dialogMessage = ping.getBody() + " Challenged You! Odds you: " + ping.getNum() + ". Choose out of:";
title = "New Challenge";
message = numberpicked;
}
builder.setTitle(title);
builder.setMessage(dialogMessage);
builder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.dismiss();
}
});
Log.d("DidStart", didStart.toString());
Log.d("Replies", replies.toString());
if (replies < 3) {
builder.setPositiveButton(buttonTitle,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Pinger pinger = mPingerAdapter.getItem(position);
// pingSomeone(pinger);
final Context context = getActivity();
EditText choosenNumber = (EditText) getView().findViewById(R.id.numberpicked);
Bundle data = new Bundle();
data.putString(PingerKeys.ACTION, GcmAction.PING_CLIENT);
String from = ping.getFrom();
data.putString(PingerKeys.TO, ping.getFrom());
//PingerKeys.NUM = "3333";
data.putString(PingerKeys.NUM, message);
Log.d("LOOK HERE ####", message);
data.putString(PingerKeys.SENDER,
mDefaultSharedPreferences.getString(RegistrationConstants.TOKEN, "Test"));
try {
GoogleCloudMessaging.getInstance(context)
.send(FriendlyPingUtil.getServerUrl(getActivity()),
String.valueOf("6969"), data);
AnalyticsHelper.send(context, TrackingEvent.PING_SENT);
} catch (IOException e) {
Log.w(TAG, "Could not ping client.", e);

}
});}
builder.show();
replies = replies + 1;

Number Picked is always null. How can I get the value of the text entered into the edit text. The dialog layout is just a linear layout with an edit text inside.
Here is the way to get the EditText value from Dialog
LayoutInflater layoutInflater = LayoutInflater.from(YourActivity.this);
View rootView = layoutInflater.inflate(R.layout.input_dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(YourActivity.this);
alertDialogBuilder.setView(rootView);
final EditText yourEditText= (EditText) rootView .findViewById(R.id.edittext);
alertDialogBuilder.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// get the `EditText` value
Toast.makeText(YourActivity.this,"EditText value" + yourEditText.getText(),Toast.LENG_SHORT).show();
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
I try to display a RatingBar in a AlertDialog (It is regularly called from a Handler).
My problem is that I can't change the number of stars. I know there is a lot of answers ot there, but always passing through the xml, which I don't want.
Can anyone help ?
public void taskRatingPopup() {
final AlertDialog.Builder popDialog = new AlertDialog.Builder(this);
final RatingBar rating = new RatingBar(this);
rating.setMax(5);
rating.setNumStars(5);
rating.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
popDialog.setIcon(android.R.drawable.btn_star_big_on);
popDialog.setTitle("BlaBla");
popDialog.setView(rating);
// Button OK
popDialog.setPositiveButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
writeRatingFile(rating.getProgress());
//Remove the dialog
dialog.dismiss();
}
})
// Button Cancel
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
popDialog.create();
popDialog.show();
}
Thanks a lot for any help !
//code block
public void itemRatingPopup() {
final AlertDialog.Builder popDialog = new AlertDialog.Builder(
mainScreen);
final RatingBar rating = new RatingBar(mainScreen);
rating.setNumStars(5);
rating.setStepSize(0.1f);
rating.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
LinearLayout parent = new LinearLayout(mainScreen);
parent.setGravity(Gravity.CENTER);
parent.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
parent.addView(rating);
// popDialog.setIcon(android.R.drawable.btn_star_big_on);
popDialog.setTitle(mainScreen.getResources().getString(
R.string.user_ratings));
popDialog.setView(parent);
// Button OK
popDialog.setPositiveButton(R.string.submit,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String fanid = StorageManager.getInstance()
.getSharedPrefs(mainScreen)
.getString(AppConstants.PREFS_FAN_ID, "0");
if (fanid != null) {
new SubmitUserRatingAsyncTask("Item", ""
+ item.getId(), fanid, rating.getRating())
.execute();
}
dialog.dismiss();
}
}).setNegativeButton(R.string.cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
popDialog.create();
popDialog.show();
}
your dialog UI will not show exactly 5 stars, it will may show any number of start because you have assign RatingBar as a root view of Dialog, for reference see the above code:
you can change rating programatically by below code:
float myRating=0f;
rating.setRating(myRating)
For adding the no. of Stars in your Rating bar,
just get the that number and use this tag.
rb_rate.setNumStars(<no.of stars,integer value>);
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);
