Checked the Checkboxes that is already checked - android

I have one EditText (edModelColor). when user click on edModelColor(EditText) then the custom dialog will be called.Custom dialog consist of RecylerView and searchview and one custom row for each item. Custom row contains ImageView(icon), TextView (colorNames) and checkbox for selection. When user click on any checkbox I passed the colorName and its position in adapter into method checkAndRemove. this method will add or remove the color name according to its adapter position and the colorNames will added into edModelColor(EditText). its working fine but the problem is that once the user click on edModelColor(EditText) again, I want to checked those checkboxes which are already checked inside CustomDialogbox.I have seen some articles online but I could not understand what they meant.
bodyColorDialog:
private void bodyColorDialog() {
TextView txtClose;
TextView tvCancel;
Button btnOk;
bodyColorDialog.setContentView(R.layout.ed_body_color_dialog);

Toast.makeText(context, "name = " + name, Toast.LENGTH_SHORT).show();
//this mthod will check if selected checkbox value is already present or not.
// It present then remove ( means user unchecked box) and if value is not there means user has selected checkbox
checkAndRemove(position,name);

Toast.makeText(context, "added", Toast.LENGTH_SHORT).show();
}
}
preview:
Conculusion: I want to check these checkboxes values when user click again on edBodyColor dialog..

I as can see, you are initializing the ArrayList of colors every time you are showing the dialog, that's why, you start always at initial state.
Instead, you should initialized the ArrayList inside onCreate() and reuse it every time to maintain the previous state.

how can get spinner values when I used if else then pass value to setonClick?

how can get spinner values when I used if else then pass value to setonClick?
in my code, I used this methods to set spinner values
DatabaseReference chk_sub = FirebaseDatabase.getInstance()......
chk_sub.addValueEventListener(new ValueEventListener() {
if(xxxxxx){
List<String> sub = new ArrayList<>();
sub.add(0, getApplicationContext().getResources().getString(R.string.choose_sub));
sub.add("USA");
sub.add("CA");
ArrayAdapter<String> dataSpinnerAdapter;
dataSpinnerAdapter = new ArrayAdapter(getApplication(), android.R.layout.simple_spinner_item, sub);
dataSpinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(dataSpinnerAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if(parent.getItemAtPosition(position).equals(getApplicationContext().getResources().getString(R.string.choose_sub))){
//do nothing
} else {
spinner_item = parent.getItemAtPosition(position).toString();
//Toast.makeText(parent.getContext(),"Selected : "+item, Toast.LENGTH_SHORT).show();
}
}
}
and I hope I can get spinner sub value because I need to judge
post.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if( -- how can get spinner value in here? --){
//
}else {
Toast.makeText(getApplication(), getApplicationContext().getResources().getString(R.string.must_upload), Toast.LENGTH_SHORT).show();
}
}
});
If you just want selected spinner item to be used in if(condition=spinner value) on click event of post i.e., post.onClick(), just get the spinner selected item
your code will look like this
post.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(spinner.getSelectedItem().equals("your compare value")){
// do whatever you want
}else {
Toast.makeText(getApplication(), getApplicationContext().getResources().getString(R.string.must_upload), Toast.LENGTH_SHORT).show();
}
}
});

why is my onclick is messing up the code?

I have a button submit_house inside a navdraw that gets a onclick listener inside a different button's (add_house) onclick listener. submit_house is the button that ends the onclick of add_house and after that it gets a new onclick. yet for some reason the first submit_house onclick does not work ( the log command there really doesn't register). why is that?
code in main.java:
building_onclick = new View.OnClickListener() {
#Override
public void onClick(final View v) {
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
#Override
public void onMapClick(LatLng point) {

// this line clears the arraylist
arrayList.clear();
// next thing you have to do is check if your adapter has changed
adapter.notifyDataSetChanged();

.position(latLng)
.icon(BitmapDescriptorFactory.fromResource(R.drawable.building15x15)));
marker.setTag(building.getMarkerId());
building.emptyBuilding();
submit_house.setVisibility(View.INVISIBLE);
add_house.setVisibility(View.VISIBLE);
submit_house.setOnClickListener(null);
}
});
}
});
}
};
Implement your activity with View.OnClickListener interface.
It will implement a method with name onClick().
Now add this line in onCreate() method : submit_house.setOnClickListener(this);
And you can perform your work in onClick() as
public void onClick(View v)
{
if(v.id==R.id.submit_house)
{
//
}
}
But you cannot perform two different functions on a single button. For that
you have to use internal variable to identify the case.

Change the background color of selected item in recyclerview

I have a recyclerview where i want to change the color of the selected item and re change it on unselected. I have used an string arraylist and an interface for that here is interface code in adapter -
public interface Callback{
void onItemClicked(String i_name, boolean longClick);
}
Here is onclick and onlongclick code-
#Override
public void onClick(View view) {
String[] tag = ((String) view.getTag()).split(":");
String i_name = tag[1];
Toast.makeText(context, ""+i_name, Toast.LENGTH_SHORT).show();
if(callback != null)
{
callback.onItemClicked(i_name,false);
}
}
#Override
public boolean onLongClick(View view) {
String[] tag = ((String) view.getTag()).split(":");
String i_name = tag[1];
if(callback != null)
{
callback.onItemClicked(i_name,false);
}
return false;
}
Here is the toggleselected code -
public void toggleSelected(String i_name)
{
final boolean newState = !selectedList.contains(i_name);
if(newState)
{
// i want to give background color to i_name
selectedList.add(i_name);
Toast.makeText(context, "selected list1- "+selectedList, Toast.LENGTH_SHORT).show();
}
else
{
selectedList.remove((String) i_name);
Toast.makeText(context, "selected list2- "+selectedList, Toast.LENGTH_SHORT).show();
}
notifyDataSetChanged();
}
here is onItemClicked code from fragment -
#Override
public void onItemClicked(String i_name, boolean longClick) {
if(longClick)
{
((MyCategoryAdaptercheckbox) MyAdapter).toggleSelected(i_name);
}
else
{
((MyCategoryAdaptercheckbox) MyAdapter).toggleSelected(i_name);
}
}
This is the code from onbindviewholder where i am settingthe tag -
getMyCategoryAdapter1 = category_name.get(i);
viewHolder.view.setActivated(selectedList.contains(i));
viewHolder.view.setTag("items:" + getMyCategoryAdapter1.getC_name());
viewHolder.view.setOnClickListener(this);
viewHolder.view.setOnLongClickListener(this);
I want to give background color to i_name on toggleselected() method.HOw can i do this.Please help.Thanks in advance.
Basic idea for selecting and disselecting items in a recyclerview.
Maintain a tag in your model for selected and unselected.
for e.x
boolean isSelected;
when you populate the data make all values in your list for isSelected false bydefault.
Then in your long press set the value of isSelected to true for that position only in your arraylist and call notifyDataSetChanged.
and in your onbindviewholder check
if(yourModel.isSelected){
// show the row selected
}else {
// show the row unselected
}
I hope you get the idea.

How to set the values which is inside the another message object as list

I have Event Message object(EventMO)..In this i have event id,name,place,date,time.....I have another one called Event Reminder days message object...In this i have type id,is selected....I used Event Reminder Days mo as list inside the EventMO....
This is my EventMO
private long eventId;
private long ringeeUserId;
private String text;
private String place;
private String eventDate;
private String startTime;
private String endTime;
private int isDelete;
private List<EventReminderDaysMO> eventReminderDaysMOs;
public List<EventReminderDaysMO> getEventReminderDaysMOs() {
return eventReminderDaysMOs;
}
public void setEventReminderDaysMOs(List<EventReminderDaysMO> eventReminderDaysMOs) {
this.eventReminderDaysMOs = eventReminderDaysMOs;
}
}
This is my event Reminder days MO
private long eventReminderDaysId;
private String eventReminderDate;
private int isSelected;
private int isMessageSent;
private int typeId;
This is my Check box code...Here i need to set type id as one for this check box....i cant directly use event reminder days MO..Because i need to pass inside EventMO as list to backend.....So how to set the value to type id,which is inside the Event MO
checkBox_aWeekBefore.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
if (((CheckBox) v).isChecked()) {
final int response = 2;
//Here only i have a problem
//eventMO.setTypeId(response); ---i cant use this...it wont be allowed
new AsyncTask<Void, Void, String>() {
protected String doInBackground(Void... arg0) {
return eventDelegates.addEvent(eventMO,context);
}
}.execute(null, null, null);
Toast.makeText(OccasionActivity.this,
"Checked", Toast.LENGTH_LONG).show();
}}
});
Using OnCheckedChangeListener(), might solve your query. For further breakdown, follow the code snippet:
Implement the OnCheckedChangeListener, as follows:
class YourClass implements OnCheckedChangeListener{/.../}
Enable the listeners to each Checkbox, as follows:
cb1.setOnCheckedChangeListener(this);
cb2.setOnCheckedChangeListener(this);
cb3.setOnCheckedChangeListener(this);
cb4.setOnCheckedChangeListener(this);
Override the onCheckedChanged method, to listen to the changes in checkbox's state:
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
buttonView.getId(); //To get id of the checkbox
}
Hope that helps.
It is not a correct way to get checkBox result, you need to add OnCheckedChangeLisenter in the place of OnItemClick.. I am giving you sample code for it....
CheckBox chk1;
CheckBox chk2;
CheckBox chk3;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
chk1 = (CheckBox) findViewById(R.id.chk1);
chk2 = (CheckBox) findViewById(R.id.chk2);
chk3 = (CheckBox) findViewById(R.id.chk3);
chk1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b == true) {
Toast.makeText(getApplicationContext(), "On Event Day Selected", Toast.LENGTH_LONG).show();
}
}
});
chk2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b == true) {
Toast.makeText(getApplicationContext(), "2 day before selected", Toast.LENGTH_LONG).show();
}
}
});
chk3.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b == true) {
Toast.makeText(getApplicationContext(), "7 day before Selected", Toast.LENGTH_LONG).show();
}
}
});
}
}
Update:----
just Check condition that Your checkbox is selected or not... if check box is selected then pass the method you want pass...
for example
chk1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b == true) {
request=2;
MOevent.setTypeId(request);
}
}
});
As you have coded for clicking on individual section, you can also get id inside this by using following code and also put it in your database.
#Override
public void onClick(View v) {
int checkBoxId = v.getId();
}

Deleting last item from spinner deletes the entire list

I am trying to use a spinner control that will enable the user to delete any list element.
I have an 'add' button to add elements to the list, and a 'delete' button that removes the currently-displayed item from the list.
It works as expected except when the user deletes the last item in the list. At that point, all of the list's items are deleted.
My code is as follows:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// grab our UI elements so we can manipulate them (for the Spinner)
// or add listeners to them (in the case of the buttons)
m_myDynamicSpinner = (Spinner)findViewById(R.id.dynamicSpinner);
m_addItemText = (EditText)findViewById(R.id.newSpinnerItemText);
Button addButton = (Button)findViewById(R.id.AddBtn);
Button clearButton = (Button)findViewById(R.id.ClearBtn);
// create an arrayAdapter an assign it to the spinner
m_adapterForSpinner = new ArrayAdapter(this, android.R.layout.simple_spinner_item);
((ArrayAdapter)m_adapterForSpinner).setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
m_myDynamicSpinner.setAdapter(m_adapterForSpinner);
// add listener for addButton
addButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
addNewSpinnerItem();
}
});
clearButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
clearSpinnerItems();
}
});
}
// add listener for addButton
private void addNewSpinnerItem() {
if (m_addItemText.getText().length() == 0) {
Toast.makeText(getApplicationContext(), "The textView is empty", Toast.LENGTH_LONG).show();
} else {
CharSequence textHolder = "" + m_addItemText.getText();
((ArrayAdapter) m_adapterForSpinner).add(textHolder);
}
m_addItemText.setText("");
}
private void clearSpinnerItems() {
m_myDynamicSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
Object t = m_adapterForSpinner.getItem(pos);
((ArrayAdapter) m_adapterForSpinner).remove((CharSequence) t);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO
}
});
}
Does anyone have any ideas or suggestions on how to make this work?
The problem with your code is that the deletion is inside the onItemSelected callback, which gets called every time you are deleting an entry, thus deleting recursively until you effectively do not have any more entries to select. If you add a log inside that method:
Log.d("Spinner", "Count: " + m_adapterForSpinner.getCount());
you will see what I mean. I'm sure you can come up with more elegant code, but a quick and dirty hack is to set up a boolean flag to stop the recursion after the first deletion. See the snippet below and add the commented lines to your own code:
public class SpinnerTest extends Activity {
Spinner m_myDynamicSpinner;
EditText m_addItemText;
ArrayAdapter m_adapterForSpinner;
public static boolean cleared = false; // <--- set up a static boolean here
#Override
public void onCreate(Bundle savedInstanceState) {
// all your code unchanged
clearButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
cleared=false; // <--- nope, we did not clear the value yet
clearSpinnerItems();
}
});
}
// code unchanged
private void clearSpinnerItems() {
m_myDynamicSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
Object t = m_adapterForSpinner.getItem(pos);
Log.d("Spinner", "Count: " + m_adapterForSpinner.getCount());
if (!cleared) // <--- did I do it already?
((ArrayAdapter) m_adapterForSpinner).remove((CharSequence) t);
Log.d("Spinner", "Count: " + m_adapterForSpinner.getCount());
cleared=true; // I did it!
}
// code unchanged
i cann't understand your question.any way you can get the position of the selected item by using getSelectedItemPosition() method.
