I have a listview in which when you select a row, it's checkbox becomes checked / unchecked. However, I have a onItemLongClick that displays a dialog.
Problem is when I long-click a row in the listview, it becomes checked and I don't want that to happen, I just need it to display a dialog. This is confusing me because the onItemClick is also called when I use onItemLongClick.
Here's the code for onItemClick:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#RequiresApi(api = Build.VERSION_CODES.N)
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
CheckBox checkBox = (CheckBox)view.findViewById(R.id.checkmark);
TextView tv3 = (TextView)view.findViewById(R.id.tx_amount);
String shitts = listView.getItemAtPosition(position).toString();
HashMap<String, String> data = new HashMap<>();
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
try {
checkBox.setChecked(!checkBox.isChecked());
String[] a = shitts.split(", ");
String[] sep = a[0].split("=");
String betamount = sep[1];
String[] sepx = a[2].split("=");
String betnumber = sepx[1];
String showbetnumber = betnumber.replaceAll("[;/:*?\"<>|&{}']","");
if(checkBox.isChecked()){
hash.put(showbetnumber,tv3.getText().toString());
}else {
tv3.setText(betamount);
checked.removeAll(Collections.singletonList(position));
hash.remove(showbetnumber,tv3.getText().toString());
}
}catch (Exception e){
}
}
});
and here's the code for onItemLongClick
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
TextView txAmt = view.findViewById(R.id.tx_amount);
AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);
alert.setTitle("Enter Amount:");
final EditText input = new EditText(MainActivity.this);
input.setInputType(InputType.TYPE_CLASS_NUMBER);
input.setRawInputType(Configuration.KEYBOARD_12KEY);
alert.setView(input);
alert.setPositiveButton("enter", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String x = input.getText().toString();
txAmt.setText(x);
}
});
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 false;
}
});
Any help is appreciated!
Create a boolean isLongClick and set it to false.
onItemLongClick(), set isLongClick to true.
On your dialog, set isLongClick to false again when any button is clicked or if the dialog was dismissed.
Finally, wrap all your code inside onItemClick() in:
if (!isLongClick) {
// onItemClick() code
}

I have ArrayList of object (citiesInSpinner) each object have two value(Id, Name)
I have already get it in alert dialog
I use this function to alert dialog:
public void test()
{
FillSpinner();
AlertDialog.Builder alertDialog = new AlertDialog.Builder(SearchFligtsActivity.this);
LayoutInflater inflater = getLayoutInflater();
View convertView = (View) inflater.inflate(R.layout.custom, null);
alertDialog.setView(convertView);
alertDialog.setTitle("Select City");
ListView lv = (ListView) convertView.findViewById(R.id.listView1);
ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,citiesInSpinner);
lv.setAdapter(adapter);
/* alertDialog.setItems(citiesInSpinner, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
/////
}
});*/
alertDialog.show();
/**/
}
now I want to make something to get the ((ID)) of item (I mean the Id of City)
I tried to do that but I failed...
any help Please !!
and thank you
Simply use
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
City city = citiesInSpinner.get(position)
//get your id -> city.Id
}
});
When the user clicks the item of list View a alert Dialog box will be displayed to the user with options like "view","delete" or "update"
the list view item. Clicking on the list view item for the first time displays the alert Dialog with options but when i click another list View item or the same list View item the second time the app crashes.Thanks in advance.
Error :java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

This is simple way to display list inside alert dialog, where in arraylist just add string whatever you have to display inside alert dialog list.
It is exactly what you need
public class MainActivity extends Activity implements OnClickListener {
private Button mDoneButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDoneButton = (Button) findViewById(R.id.done_button);
mDoneButton.setOnClickListener(this);
}
#Override
public void onClick(View v) {
final CharSequence[] items = {
"Rajesh", "Mahesh", "Vijayakumar"
};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Make your selection");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
// Do something with the selection
mDoneButton.setText(items[item]);
}
});
AlertDialog alert = builder.create();
alert.show();
}
}

I want to put a string in a EditText in a AlertDialog,which is in a onItemClick Listener with a ListVIew.Here is the part of code
dialogbuilder= new AlertDialog.Builder(this)
.setTitle(R.string.title_connect_dialog)
.setView(getLayoutInflater().inflate(R.layout.dialog_connect,null))
.setPositiveButton("Connect", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
})
.setNegativeButton("Cancel",new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
})
.create();
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View view = inflater.inflate(R.layout.dialog_connect, null);
edit1 = (EditText)view.findViewById(R.id.devicename);
edit2 = (EditText)view.findViewById(R.id.deviceadd);
private AdapterView.OnItemClickListener mDeviceClickListener = new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> adapterView, View v, int arg2, long arg3) {
String info = ((TextView) v).getText().toString();
name = info.substring(0,info.length() - 18);
address = info.substring(info.length() - 17);
dialogbuilder.show();
edit1.setText(name);
edit2.setText(address);
}
};
When I run the project,there is nothing in the EditText!It does not work!But there is no exception or error.I tried only set text in the XML file can work.I replaced EditText with TextView ,but is not work too.
Are there something wrong in logical?Thank you for reading.
Use as view instance for accessing Views form Dialog layout which you are passing in setView method of AlertDialog.Builder change:
.setView(getLayoutInflater().inflate(R.layout.dialog_connect,null))
to
.setView(view)
EDIT:
or instead of inflate layout again to access views you should use dialogbuilder instance to initialize EditText as:
edit1 = (EditText)dialogbuilder.findViewById(R.id.devicename);
edit2 = (EditText)dialogbuilder.findViewById(R.id.deviceadd);
You are showing the Dialog before setting the text
dialogbuilder.show();
edit1.setText(name);
edit2.setText(address);
Try changing that around
edit1.setText(name);
edit2.setText(address);
dialogbuilder.show();
I have a ListView with each row consisting of a textview and a checkbox.
The user is allowed to click on each TextView, and once he does a DialogBox is presented to him where he is expected to either choose Yes or No.
When he chooses No, the CheckBox next to the TextView the user clicked needs to be ticked automatically.
The problem that I am facing is that no matter which TextBox the user chooses, the last CheckBox of the list gets ticked all the time, and not the one next to the chosen TextView.
After debugging I noticed that this is happening because the getView() method of the adapter class stops on the last row, thus the last row always gets selected. I tried setting up tags for each row so that I can than tick the checkbox accordingly but then neither Checkboxes get ticked.
I would appreciate any help on this matter.
....
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
.....
holder.text.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(final View v)
{
final AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setTitle("Materials");
builder.setMessage("Did you require any materials to fix this error?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
String clickedError;
clickedError = holder.text.getText().toString();
Intent intent = new Intent(mContext, Material.class);
intent.putStringArrayListExtra("materialList", materialList);
intent.putExtra("clickedError", clickedError);
intent.putExtra("repairID", repairID);
((Activity)mContext).startActivityForResult(intent, 1);
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
//holder.chk.setChecked(true); // This ticks the last checkbox of the list.
if(holder.chk.getTag() == v.getTag())
{
holder.chk.setChecked(true);
}
}
});
builder.show();
}
});
Try passing the checkbox for the row into your on click listener:
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
.....
holder.text.setOnClickListener(new MyClickListener(holder.chk);
}
private class MyClickListener implements OnClickListener
{
Checkbox checkbox = null;
public MyClickListener(final Checkbox checkbox)
{
this.checkbox = checkbox;
}
#Override
public void onClick(final View v)
{
final AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setTitle("Materials");
builder.setMessage("Did you require any materials to fix this error?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
String clickedError;
clickedError = holder.text.getText().toString();
Intent intent = new Intent(mContext, Material.class);
intent.putStringArrayListExtra("materialList", materialList);
intent.putExtra("clickedError", clickedError);
intent.putExtra("repairID", repairID);
((Activity)mContext).startActivityForResult(intent, 1);
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
//checkbox.setChecked(true); // This ticks the last checkbox of the list.
if(checkbox.getTag() == v.getTag())
{
checkbox.setChecked(true);
}
}
});
builder.show();
}
});
CheckBox extends TextView. Use CheckBox.setText(CharSequence | int) to set text into CheckBox and remove the TextView (that will not solve your check problem, of course). Regarding your problem - it's because most AdapterView's re-use Views. Store the checked item information somewhere and in getView call setChecked(checkedItems.get(pos)).
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
.....
holder.chk.setChecked(checkedItems.get(position))
.....
builder.setNegativeButton("No", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
//holder.chk.setChecked(true); // This ticks the last checkbox of the list.
if(holder.chk.getTag() == v.getTag())
{
holder.chk.setChecked(true);
checkedItems.put(position, true);
}
}
});
}
Where checkedItems is a SparseBooleanArray
I have my ListActivity that when you tap on an item, it pops up a Dialog that ask the user for user and password. How can I get the selected position from the dialog?
Here's how I initialize the ListActivity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ListView listView = getListView();
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
showDialog(DIALOG_USER_PASSWORD);
}
});
}
The Dialog I pop up is a simple AlertDialog with 2 EditText which I inflate from an xml file
protected Dialog onCreateDialog(int id) {
switch (id) {
...
case DIALOG_USER_PASSWORD:
LayoutInflater factory = LayoutInflater.from(this);
final View dialogView = factory.inflate(R.layout.alert_dialog_text_entry, null);
return new AlertDialog.Builder(MyListActivity.this)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.ask_user_password)
.setView(dialogView)
.setPositiveButton(R.string.ok_text, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String userName = ((EditText) findViewById(R.id.username_edit_alert_dialog))
.getText().toString();
String password = ((EditText) findViewById(R.id.password_edit_alert_dialog))
.getText().toString();
Credentials cred = new CredentialsL1(userName, password);
/* HERE IS WHERE i NEED THE SELECTED ITEM
mId IS THE OBJECT ASSOCIATED TO THE SELECTED POSITION */
mService.connect(mId, cred);
}
})
// Cancel button
.setNegativeButton(R.string.cancel_text,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
})
.create();
}
return null;
}
The only I've come up with is creating a new field "mId" and setting it when the user taps and using it when the user taps OK in the Dialog. Any more elegant idea?
Thanks
private int selectedPosition;
...
protected void onCreate(Bundle savedInstanceState) {
....
// inside the item listener...
selectedPosition = position;
showDialog(DIALOG_USER_PASSWORD);
/* HERE IS WHERE i NEED THE SELECTED ITEM
mId IS THE OBJECT ASSOCIATED TO THE SELECTED POSITION */
// just use selectedPosition var
Any more elegant idea?
It seems that you use a normal ListView (not a checkbox one)... so, it's fine to do it this way.
