How To Add Changing Number Of EditText Objects in AlertDialog

I'm Developing a game so I want to get player name using an AlertDialog. But I don't Know certain number of players, it's Variable between 2 to 16!
I've added an spinner to ask about the NumberOfPlayers and a Button to Show AlertDialog then I tried to add certain number of EditText Using for loop. It doesn't have error but when I run application on phone, I just have Ok and Cancel Buttons. I couldn't resolve problem and become appreciate if someone help me.
This is My AlertDialog
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Opponents:");
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
final EditText[] input = new EditText[NumberOfPlayers];
for (int aux=0;aux==NumberOfPlayers;aux++) {
input[aux].setInputType(InputType.TYPE_CLASS_TEXT);
layout.addView(input[aux]);
}
builder.setView(layout); // this is a set method, not add
// Set up the buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
for (int aux=0;aux==NumberOfPlayers;aux++){
//PlayersTXT[aux].setText(input[aux].getText().toString());
}
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
builder.show();

Just change your code with below one and you will get dynamic edittext in alert dialog:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Opponents:");
LinearLayout layout = new LinearLayout(this);
layout.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
layout.setOrientation(LinearLayout.VERTICAL);
final EditText[] input = new EditText[NumberOfPlayers];
for (int aux=0;aux<NumberOfPlayers;aux++) {
input[aux] = new EditText(MainActivity.this);
input[aux].setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
input[aux].setInputType(InputType.TYPE_CLASS_TEXT);
layout.addView(input[aux]);
}
builder.setView(layout); // this is a set method, not add
// Set up the buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
for (int aux=0;aux==NumberOfPlayers;aux++){
//PlayersTXT[aux].setText(input[aux].getText().toString());
}
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
builder.show();
Let me highlight problems in your code are:
you are using "aux==NumberOfPlayers" in "for loop" which is wrong. it should be "aux < NumberOfPlayers"
you are not initializing edittext in "for loop" such as "input[aux] = new EditText(MainActivity.this);"
you are not giving height and width for both linear layout as well edittext after initializing such as ".setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));"

must call removeView() on the child's parent first

I'm creating a chat application and facing a problem while creating a group (Recycler View's List item) and to inflate it over the fragment container.
Actually, two kind of views are being inflated. One is the root View that will be inflated in a fragment container and second is inflated as another custom layout for Dialog ask for input group name.
FAB is implemented as a click event to launch Dialog to input channel name. First time when i click a FAB, dialog appears ask for channel name to create group. After passing, an input group is created and Channel/Group (Recycler View's List item) is created and inflated over the container. But second time when I click on FAB, to repeat the process, to create another group/channel, the app crashes and error is encountered on logcat.
"The specified child already has a parent. You must call removeView() on the child's parent first".
I don't have too much knowledge about fragments and don't know what does that error means. Please help to resolve this error.
Thanks

How to hide the specific row, When I click delete the specify row in listview

I can hide the specific row, but i come back to the listview activity it will show again the specific row that I hide. Here is my code in below:
listView.setLongClickable(true);
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, final View v, final int position, long id) {
//Do your tasks here
textViewID = (TextView) v.findViewById(R.id.text_customerid);
custid = textViewID.getText().toString();
AlertDialog.Builder alert = new AlertDialog.Builder(
TableRecordActivity.this);
alert.setTitle("Alert!!");
alert.setMessage("Are you sure to delete record");
alert.setPositiveButton("YES", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//databaseHelper = new DatabaseHelper(getApplicationContext());
//sqLiteDatabase=databaseHelper.getReadableDatabase();
//databaseHelper.deleteCustomerInformation(custid,sqLiteDatabase);
LinearLayout parentLayout = (LinearLayout) v.findViewById(R.id.linearLayout);
parentLayout.setVisibility(View.GONE);
//Intent intent = new Intent(getApplication(),TableRecordActivity.class);
//intent.putExtra("user_id2",user_id2);
//intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
//startActivity(intent);
Toast.makeText(getApplicationContext(),"Customer deleted",Toast.LENGTH_LONG).show();
dialog.dismiss();
}
});
alert.setNegativeButton("NO", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alert.show();
return true;
}
});

You need to delete the element in the List who is linked to the adapter.
yourArrayList.remove(position);

You already get the position of the item you clicked on, here :
public boolean onItemLongClick(AdapterView<?> parent, final View v, final int position, long id) {
}
Now remove the item from the data-source (ArrayList?):
list.remove( position );
And refresh the list:
adapter.notifyDataSetChanged();

you need to notify the list view using notifyDataSetChanged() method. Since you got the position in the setOnItemLongClickListener() with the help of that you can remove that particular object from the list (or) array, then you need to update the list in the adapter and notify the adapter. Hopefully this Link is helpful.
In the above link explains removing the data on longClick and sending the updated data to the adapter and notifying the list is clearly explained.

Google Map flickers under alert dialog due to being compressed

I have implemented a dialog box on my marker info box click listener and the code logic is working fine, but when I show the dialog box the map is pushed up and flickers in the back ground. I tried it on a Pixel emulator as well as Galaxy S8 and both show the map as flickering behind the alert dialog box.
Here is the image and you can not really see it flickering but the text is distorted and flickering. It looks like its being compressed between the keyboard and top. The word ...calculating is on the bottom of the screen with no dialog so not sure why its at the top.
Any help would be appreciated. I did check for similar questions and what I think I am after is the keyboard simply overlaying the image not pushing it up.
googleMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker marker) {
showEditTextDialog();
}
});
public void showEditTextDialog()
{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater layoutInflater = LayoutInflater.from(this);
final View dialogView = layoutInflater.inflate(R.layout.mymap_marker_alert_dialog, null);
final EditText editText = (EditText) dialogView.findViewById(R.id.alert_dialog_editText);
// Keyboard
final InputMethodManager imm = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
// Auto show keyboard
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean isFocused) {
if (isFocused)
{
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}
}
});
builder.setView(dialogView)
.setPositiveButton("Okay", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
String regNum = editText.getText().toString();
Log.d("STACKOVERFLOW", "Registration number: " + regNum);
// Hide keyboard
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// Hide keyboard
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
dialog.cancel();
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
}

SO it was the Adview that was trying to show in the compress screen area above the keyboard. I had to find a way to remove the adview while the keyboard was visible and then return it again on the keyboard was dismissed. In my case I had to ensure to re-enable the adview in the Alert Dialog onclick methods and the full solution is as follows:
Set up your LinearLayout and note the #id for both the LinearLayout and adView.
<TextView
android:id="#+id/mydistanceToMarker"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentStart="true"
android:gravity="fill"
android:text="Tap to change map type."
android:textAlignment="center"
android:textSize="36sp"
android:textColor="#color/colorBlack"
android:textStyle="bold" />
<com.google.android.gms.ads.AdView
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="#+id/myAdMapView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
ads:adUnitId="#string/UNIT_ID"
ads:adSize="BANNER"/>
</LinearLayout>
Connect the variable to the LinearLayout
private LinearLayout parentLinearLayout;
and
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_map);
parentLinearLayout = (LinearLayout) findViewById(R.id.mydistanceLayout);
NOTE: I have a few LinearLayout layers in my xml file so this #id is for the LinearLayout that just contains the adView that I need to remove and re-add when needed, NOT the top level LinearLayout.
In my progarm logic that is not included and irrelevant, I call the Alert Dialog method
public void showEditTextDialog()
{
parentLinearLayout.removeView((View) adMapView);
Here I remove the add at the start of the Alert Dialog and since I force the keyboard to show immediately and I need the ad not to be visible.
Now at the OK and Cancel responses in the Alert Dialog I add the view back.
builder.setView(dialogView).setPositiveButton("Okay", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
parentLinearLayout.addView((View) adMapView);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) { imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
dialog.cancel();
parentLinearLayout.addView((View) adMapView);
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
And this fixed the issue. Not sure if it was the best solution and happy to edit or fix the solution if there is a better way, but it solved my issue. Hope it helps someone in the same situation.

Cannot set EditText? Issue From dialog in a fragment - Strange - Android Java

I've come across an issue which I've never had before. I have a Fragment containing a button. This button (ViewBookingButton) shows a popup dialog. When the dialog opens I would like to set a string in an EditText (AllBooking). Unfortunately it crashes and shows NullPointerExecption. What is going wrong? Here is my code:
ViewBookingButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
AlertDialog.Builder ViewBookingHelpBuilder = new AlertDialog.Builder(getActivity());
ViewBookingHelpBuilder.setTitle("view booking:");
LayoutInflater inflater = getActivity().getLayoutInflater();
View DialogLayout = inflater.inflate(R.layout.view_booking, null);
ViewBookingHelpBuilder.setView(DialogLayout);
TextView AllBooking = (TextView)view.findViewById(R.id.AllBooking);
AllBooking.setText("Hello World");//WHEN I REMOVE THIS THE DIALOG WORKS
ViewBookingHelpBuilder.setPositiveButton("Done", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which)
{
}
});
AlertDialog helpDialog = ViewBookingHelpBuilder.create();
helpDialog.show();
}
});

Change this
TextView AllBooking = (TextView)view.findViewById(R.id.AllBooking);
to
TextView AllBooking = (TextView)DialogLayout.findViewById(R.id.AllBooking);
TextView belongs to the inflated layout and `findViewById looks for the view in the current view hierarchy.
