I am trying to view specific icons based on the selected radio button using an if statement.
I didn't want to use a listener since I'm clicking a submit button anyway.
I have 3 buttons: Party, Accident and Other.
When running my code my Log message shows that I always get "other" (else clause) as a checked value, even when it is not.
I have tried so many different ways from many different threads on Stack Overflow but I'm afraid I might be doing something else wrong.
Here is the code:
private void addMarkerToMap() {
AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
View view = getLayoutInflater().inflate(R.layout.dialoglayout, null);
streetname = (EditText) view.findViewById(R.id.streetname_input);
title = (EditText) view.findViewById(R.id.title_input);
description = (EditText) view.findViewById(R.id.description_input);
radioGroup = (RadioGroup) view.findViewById(R.id.radioGroup);
final int selectedID = radioGroup.getCheckedRadioButtonId();
radioButton = (RadioButton) view.findViewById(selectedID);
Button addButton = (Button) view.findViewById(R.id.add_button);
Button cancelButton = (Button) view.findViewById(R.id.cancel_button);
builder.setView(view);
final AlertDialog dialog = builder.create();
dialog.show();
addButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addMarker(streetname, title, description);
}
});
cancelButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
}
private void addMarker(EditText streetname, EditText title, EditText description) {
String streetnameText = streetname.getText().toString();
String titleText = title.getText().toString();
String descriptionText = description.getText().toString();
String radioText = radioButton.getText().toString();
BitmapDescriptor icon; //= BitmapDescriptorFactory.fromResource(R.drawable.standard); //has to have a standard value
//Log.d("id", "id" + ID);
Log.d("radioText", "text: " + radioText);
if(streetnameText.isEmpty() || titleText.isEmpty() || descriptionText.isEmpty()) {
Toast.makeText(this, "One of the textboxes is empty. Please fill in all textboxes", Toast.LENGTH_LONG).show();
} else {
if(radioText.equals("Accident")){
icon = BitmapDescriptorFactory.fromResource(R.drawable.accident);
}
else if(radioText.equals("Party")){
icon = BitmapDescriptorFactory.fromResource(R.drawable.party);
}
else {
icon = BitmapDescriptorFactory.fromResource(R.drawable.standard);
}
MarkerOptions markerOptions = new MarkerOptions().position(latlngGlobal)
.title(titleText)
.snippet(descriptionText)
.icon(icon);
//TODO add new marker
mMarker = mGoogleMap.addMarker(markerOptions);
// TODO Get location for marker, add to database
}
}
I have also tried using this instead but it's the same result (gives ID of "other"):
if(ID == R.id.accident_radio){
icon = BitmapDescriptorFactory.fromResource(R.drawable.accident);
}
else if(ID == R.id.party_radio){
icon = BitmapDescriptorFactory.fromResource(R.drawable.party);
}
else {
Log.d("id", "id" + ID);
icon = BitmapDescriptorFactory.fromResource(R.drawable.standard);
}
You declared radioButton as the selected radio button in the group at that specific time only, you don't do any new declarations for it before calling addMarker(...) so it will always be the same.
Instead of:
String radioText = radioButton.getText().toString();
Try something like this (but make it nicer):
String radioText = ((RadioButton) view.findViewById(((RadioGroup) view.findViewById(R.id.radioGroup)).getCheckedRadioButtonId())).getText().toString();

I'm trying to build a layout that has a textView that has a number, an editText that has a hint for the entered item and a button, and when i press on the button i'll get the entered text and put it inside a variable and then decrease the number that is inside the text view until it is 0
here's the piece of my code:
job = "";
adjective = "";
this.changeMyEditText(2, "job");
job = this.getMyText();
this.changeMyEditText(1, "adjective");
adjective = this.getMyText();
scan.close();
and here's the changeMyEditText function:
public void changeMyEditText(int num, String type) {
TextView numOfEnteredWords = (TextView) findViewById(R.id.numOfEnteredWords);
EditText enteredWord = (EditText) findViewById(R.id.enteredWord);
numOfEnteredWords.setText(num + " word(s) left");
enteredWord.setHint(type);
}
and the getMyText method:
public String getMyText() {
EditText enteredWord = (EditText) findViewById(R.id.enteredWord);
return enteredWord.getText().toString();
}
On button's click listener event, you can decrease textViewNumber -1.
and can check on every button's click if number = 0 then do whatever you want to do.
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (textViewNumber != 0) {
textViewNumber--; //I guess if you want to change number by -1
} else {
// Your action on textviewNumber become 0
}
}
});
problem: I set point breaks at the following code:
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_NAME, workoutName);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_DAYS, workoutDays);
, both showed up as null when I ran the app in debug mode. workoutName contains a simple String that is passed to a new activity, whereas workoutDays constains an array of String.
the full code is provided below:
public class CreateWorkoutActivity extends Activity {
public final String TAG = this.getClass().getSimpleName();
protected String[] workoutDays = new String[7];
protected String workoutName;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_workout);
Button mNextButton = (Button) findViewById(R.id.next_button1);
CheckBox satBox = (CheckBox) findViewById(R.id.sat_checkbox);
CheckBox sunBox = (CheckBox) findViewById(R.id.sun_checkbox);
CheckBox monBox = (CheckBox) findViewById(R.id.mon_checkbox);
CheckBox tuesBox = (CheckBox) findViewById(R.id.tues_checkbox);
CheckBox wedBox = (CheckBox) findViewById(R.id.wed_checkbox);
CheckBox thursBox = (CheckBox) findViewById(R.id.thurs_checkbox);
CheckBox friBox = (CheckBox) findViewById(R.id.fri_checkbox);
final EditText mWorkoutName = (EditText) findViewById(R.id.workout_name1);
workoutName = mWorkoutName.getText().toString();
Log.i(TAG, workoutName);
if (satBox.isChecked()) {
workoutDays[0] = new String(satBox.getText().toString());
}
if (sunBox.isChecked()) {
workoutDays[1] = new String(sunBox.getText().toString());
}
if (monBox.isChecked()) {
workoutDays[2] = new String(monBox.getText().toString());
}
if (tuesBox.isChecked()) {
workoutDays[3] = new String(tuesBox.getText().toString());
}
if (wedBox.isChecked()) {
workoutDays[4] = wedBox.getText().toString();
}
if (thursBox.isChecked()) {
workoutDays[5] = satBox.getText().toString();
}
if (friBox.isChecked()) {
workoutDays[6] = friBox.getText().toString();
Log.i(TAG, workoutDays[6]);
}
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i(TAG, workoutDays.toString());
Intent intent = new Intent(CreateWorkoutActivity.this, WorkoutRoutinesActivity.class);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_NAME, workoutName);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_DAYS, workoutDays);
Log.i(TAG, workoutDays.toString());
startActivity(intent);
}
});
}
The problem is not in the intent, but in the way you obtain workoutName (this is the null value). You create the activity, set up final EditText mWorkoutName = (EditText) findViewById(R.id.workout_name1); and then immediately ask for the input value through workoutName = mWorkoutName.getText().toString();, but at this time the user still hasn't entered anything. You should put that second line in the listener below (so its activated only after the user presses mNextButton. It's a good idea to put some check after it and send a message to user that they need to fill in that field (if it is indeed necessary).
Looks like the values for workoutName and workoutDays are not filled in initially when the view is created. You should move retrieving the value from the text fields to your onClickListener function.
you checking the CheckBox and EditText in onCreate, absolutely the EditText will be empty and all CheckBox it not checked
I'm making a quiz app. User has to finish the phrase shown on display and write the name of the car in the edittext, after pushing on button, if the answer right, edittext become green, if doesn't, become red. If all answers right (green), intent move on next activity.
I have some difficulties with if statement edit text become red even the answer was right. Also how to make INTENT to move on next activity if all right, if not it doesn't move?
public class MainActivity extends AppCompatActivity {
EditText et_one_one, et_one_two, et_one_three;
Button buttonCheck;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_one_one = (EditText) findViewById(R.id.et_one_one);
et_one_two = (EditText) findViewById(R.id.et_one_two);
et_one_three = (EditText) findViewById(R.id.et_one_three);
final String t1 = et_one_one.getText().toString();
final String t2 = et_one_two.getText().toString();
final String t3 = et_one_three.getText().toString();
buttonCheck = (Button) findViewById(R.id.buttonCheck);
buttonCheck.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (t1.equals("maserati")){
et_one_one.setBackgroundColor(Color.GREEN);
}
else {
et_one_one.setBackgroundColor(Color.RED);
}
if (t2.equals("mercedes")){
et_one_two.setBackgroundColor(Color.GREEN);
}
else{
et_one_two.setBackgroundColor(Color.RED);
}
if (t3.equals("bmw")){
et_one_three.setBackgroundColor(Color.GREEN);
}
else{
et_one_three.setBackgroundColor(Color.RED);
}
}
});
}
}
You're changing the color of just the et_one_one each time in your if else statements. Shouldn't it be for different edittexts?
buttonCheck.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean allAnswersCorrect = true;
String t1 = et_one_one.getText().toString();
String t2 = et_one_two.getText().toString();
String t3 = et_one_three.getText().toString();
if (t1.equals("maserati")){
et_one_one.setBackgroundColor(Color.GREEN);
}
else {
allAnswersCorrect = false;
et_one_one.setBackgroundColor(Color.RED);
}
if (t2.equals("mercedes")){
et_one_two.setBackgroundColor(Color.GREEN);
}
else{
allAnswersCorrect = false;
et_one_two.setBackgroundColor(Color.RED);
}
if (t3.equals("bmw")){
et_one_three.setBackgroundColor(Color.GREEN);
}
else{
allAnswersCorrect = false;
et_one_three.setBackgroundColor(Color.RED);
}
if(allAnswersCorrect){
Intent intent = new Intent(YourActivity.this, YourSecondActivity.class);
startActivity(intent);
}
}
});
Maintain a allAnswersCorrect boolean to check whether your answers are correct or not. If all are correct the move to your next activity.
You should use t2.equals("maserati"), and it will be ok.
I have an activity with a button, when the user clicks on the button, an AlertDialog appear with 2 EditText where you put email and password to login.
When I try to get the text from the EditText i always get only empty strings.
The layout login_alert is the layout of the AlertDialog.
Here the code:
View view = getLayoutInflater().inflate(R.layout.login_alert, null, false);
String email = ((EditText) view.findViewById(R.id.emailEditText)).getText().toString();
String password = ((EditText) view.findViewById(R.id.passwordEditText)).getText().toString();
System.out.println("DEBUG: "+email+", "+password); // Empty strings
EDIT:
Activity code:
public class MainActivity extends FragmentActivity {
public static final String mAPP_ID = "...";
public static final String USER_DB_URL = "...";
AssetsExtracter mTask;
private MainFragment mainFragment;
private List<User> usersList = new ArrayList<User>();

PROBLEM SOLVED, SOLUTION:
In the onCreate() I inflate the alert_dialog layout in a View variable. I made that View variable global (before onCreate()) and then in onLabLoginButtonClick() I don't inflate the view again, but I use that global instantiated in the onCreate(). hope its clear. thank you all!
You getText just after initialization. Untill you have text in xml you won't get the text. In onclick of alertdialog button get the text.
Declare
EdiText ed1,ed2; // before onCreate if in activity and onCraeteView in fragment
as a instance variable
View view = getLayoutInflater().inflate(R.layout.login_alert, null, false);
ed1= (EditText) view.findViewById(R.id.emailEditText))
ed2 = (EditText) view.findViewById(R.id.emailEditText);
then on Alert dialog Button click
String email = ed1.getText().toString();
String password= ed2.getText().toString()
you must get the text when you click on login button of alert dialog box
the above mentioned code you get text when you show alert dialog it always return always empty string you should follow the following procedure
first you make a custom alert box layout having two edit text and one button
user write text to edittext for login and give password and then click login button
when you call login button click listener you can get text of edittext easyly
You are trying to get the text immediately after you inflated the view. Try doing it when the user clicks the done button instead.
Before onCreate add:
EditText email;
EditText pass;
Add this in your onCreate
etEmail (EditText) view.findViewById(R.id.emailEditText);
etPass (EditText) view.findViewById(R.id.emailEditText);
Then add this to when your button is clicked
String email = etEmail.getText().toString();
String pass = etEmail.getText().toString();
Just ensure that the editText.getText.toString() method is inside the OnClick() method, eg:
TextView submit = enquiryFragment.findViewById(R.id.query_submit_button);
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v){
query_type = query_type_editText.getText().toString();
query_text = query_editText.getText().toString();
if (query_text.length()!=0 && query_type.length()!=0) {
postQuery(query_type, query_text, store_id);
// Log.e("query_type ",query_type );
}else{
Toast.makeText(getContext(), "Enter something !", Toast.LENGTH_SHORT).show();
}
}
});
Alternatively add a TextChangedListener to you textview to change the change the string every time the textboxtext changes.
A textwatcher is also possible
you should get the text when you click on save or done button.
If you get this text on click of alert dialog button, you may end up taking it multiple times.
I am developing a android App which is totally based on request and response from servlet.I have populate some data in customize Alert-dialog Where i using two thing one is cross button that will delete item from list in alert-dialog and update view of alert dialog , second thing is close button that will suppose to dismiss this alert-dialog. I am showing full coding of my alert-dialog. I calling alert dialog on button click by all these method.
intiliazeOrderListDialog();
showOrderListDialog();
My decleration is as follow
public AlertDialog detailsDialog, orderDialog;
AlertDialog.Builder builder;
Now i am going to post my intiliazeOrderListDialog() block.
public void intiliazeOrderListDialog() {
builder = new AlertDialog.Builder(MainScreen.this);
mContext = getApplicationContext();
inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
orderDialogLayout = inflater.inflate(R.layout.my_order_list,(ViewGroup)findViewById(R.id.order_list_root));
orderList = (ListView) orderDialogLayout.findViewById(R.id.order_list);
ibOrderDelete = (ImageButton)orderDialogLayout.findViewById(R.id.deleteOrder);
tvPrice = (TextView) orderDialogLayout.findViewById(R.id.order_list_total);
tvTaxes = (TextView) orderDialogLayout.findViewById(R.id.order_list_taxes);
tvTotal = (TextView) orderDialogLayout.findViewById(R.id.order_list_grand_total);
Button bclose = (Button) orderDialogLayout.findViewById(R.id.close);
Button bPlaceOrder = (Button) orderDialogLayout.findViewById(R.id.my_order_placeorder);
bclose.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
orderDialog.dismiss();
System.out.println(" click on closowse");
}
});
bPlaceOrder.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
System.out.println("Place order click");
palceMyOrdertoServer();
new SendOrderFromTable().execute();
System.out.println("place order to server is called");
String msg = "Your Order is Successfully placed to Kitcken";
Message msgObject = new Message();
msgObject.what = 1;
msgObject.obj = msg;
addMenuItemHandler.sendMessage(msgObject);
orderDialog.dismiss();
}
});
}
and at last i am going to post showOrderListDialog(); block
public void showOrderListDialog() {
builder.setView(orderDialogLayout);
orderDialog = builder.create();
orderDialog.show();
}
I know i have posted too many codes but its conveniences for those who want to help me . I have a very simple problem why my
orderDialog.dismiss();
is not working for me.? Thanks in advance to all .
Finally i solve my own issue . "Self help is best help ;;".
It was issue of calling method in setOnClickListener.
I just call it,
android:clickable="true"
android:onClick="clickHandler"
if (v.getId() == R.id.myOrder) {
System.out.println("Click my Order");
System.out.println("OrderListAdapter.totalCount ="
+ OrderListAdapter.totalCount);
// select COUNT(*) from CDs;
int jcount = 0;
jcount = countjournals();
System.out.println("jcount = " + jcount);
// Count implementation at my Order
if (jcount < 1) {
alertShow();
} else {
intiliazeOrderListDialog();
showOrderListDialog();
}
// startActivity(new Intent(RestaurantHome.this,
// MyOrderList.class));
}
