I am new to Android development and I am having a hard time wrapping my head around the android listviews. I pretty much went through entire google search and tried every "possible" solution, but without really getting the listview, I am having a hard time solving this problem.
I want to disable particular button when I click the complete_btn in listview item.
Right now, the complete_btn.setOnClickListener in the else {} part is giving me the null pointer exception (it's fine in the if(converView == null) part). If I remove the code, everything works fine, but even simply commenting out everything in the listener does not work.
I want to eventually disable the button if Yes is clicked in the Alert dialog that pops up when the button is pressed! Could someone please help me with this??

I am stuck with a simple problem of getting text from editText.
fab1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AlertDialog.Builder placeLLDialog= new AlertDialog.Builder(PlacesActivity.this);
LayoutInflater inflater = getLayoutInflater();
final View view = inflater.inflate(R.layout.place_add_dialog, null);
placeLLDialog.setView(R.layout.place_add_dialog);
final EditText place = view.findViewById(R.id.placeName);
final EditText lati = view.findViewById(R.id.placeLati);
final EditText longi = view.findViewById(R.id.placeLongi);
placeLLDialog.setTitle("Add Place with Latitude and Longitude")
.setPositiveButton("Add", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Log.e(TAG, "Helloooo" + place.getText().toString());
if(!place.getText().toString().equals("") &&
!lati.getText().toString().equals("") &&
!longi.getText().toString().equals("")) {
Log.e(TAG, "Hello" + place.getText().toString());
final Places places = new Places(place.getText().toString(),
lati.getText().toString(), longi.getText().toString());
mPlacesViewModel.insert(places);
}
closeFABMenu();
}
})
.setNegativeButton("Cancel", null)
.show();
}
When I am doing this, I am not getting the value of place, lati and longi,
i.e. "place.getText().toString()" is empty.
Can anybody kindly help me with this strange problem?
You are inflating the view here:
final View view = inflater.inflate(R.layout.place_add_dialog, null);
but you are not using it just one line after:
placeLLDialog.setView(R.layout.place_add_dialog);
So you should be setting:
placeLLDialog.setView(view);
fab1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AlertDialog.Builder placeLLDialog = new AlertDialog.Builder(PlacesActivity.this);
LayoutInflater inflater = getLayoutInflater();
final View view = inflater.inflate(R.layout.place_add_dialog,null);
placeLLDialog.setView(view);
final EditText place=(EditText)view.findViewById(R.id.placeName);
final EditText lati = (EditText)view.findViewById(R.id.placeLati);
final EditText longi = (EditText)view.findViewById(R.id.placeLongi);
placeLLDialog.setTitle("Add Place with Latitude and Longitude")
.setPositiveButton("Add", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Log.e(TAG, "Helloooo" + place.getText().toString());
if(!place.getText().toString().equals("") && !lati.getText().toString().equals("") && !longi.getText().toString().equals("")) {
Log.e(TAG, "Hello" + place.getText().toString());
final Places places = new Places(place.getText().toString(),lati.getText().toString(), longi.getText().toString());
mPlacesViewModel.insert(places);
}
closeFABMenu();
}
})
.setNegativeButton("Cancel", null)
.show();
}
});
I am working on an app in android studio.
My app has a listview, whiche has Edittext , textview and checkbox in its row.
my proplem is when I have more than five items in my listvew, the listview lost focus, for example: when I press on checkbox on the 6th item , the textview shows me the name from the first item.
I wish I could explain my proplem very well.

I think the error is the way your arrayPeople List is being populated, if you say the sixth item gets you the first you can try reversing the order with
Collections.reverse(arrayPeople);
you can place this line of code below your holder.cbm.setOnClickListener on your adapter
Hope it helps.

You can't add values in getView. let's do it in activity
This line will not set, holder.t1.setText(NewItem);
If I move it to the parent onClick, with a hardcoded string (for testing) it does.
Keep in mind, this is inside a getView method of an ArrayAdapter. I am trying to setText to ListView rows.
Edit:
EXPANDED, COMPLETE getView() -- AS REQUESTED
(Did not have time to edit, will later, sorry!)

From what you've said in the above comments, this is the intended function. Since,
Except, the dialog does dismiss, I get the toast and the task runs correctly.
This is coded into your onClick() here:
bInsert.setOnClickListener(new OnClickListener() {
#SuppressWarnings("unchecked")
public void onClick(View v) {
NewItem = etEdit.getText().toString();
if (NewItem.equals("")) {
Toast.makeText(getContext(),
"Please add something first.",
Toast.LENGTH_SHORT).show();
} else {
holder.t1.setText(NewItem);
passing.add(NewItem);
dialog.dismiss();
new EditCommentTask().execute(passing);
}
}
});
Specifically, this is executing:
if (NewItem.equals("")) {
Toast.makeText(getContext(),
"Please add something first.",
Toast.LENGTH_SHORT).show();
}
so I am assuming your problem is with NewItem, I never see where you actually initialize it, but I am assuming it .equals("") since this is executing. Try throwing a Log.d or println() just below the line NewItem = etEdit.getText().toString(); to see what the value of NewItem is at this point.
I read many more realted to this problem but not getting more idea. After this, i am trying to post, here in this picture I have 3 items on list, I have 2 item click. So I want to delete these two checked item. But i am the newbie for android, So could not get more idea behind this.
Code
public class CountryList extends Activity implements OnClickListener,
OnItemClickListener {
private static class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return tempCountry.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.bookmarks_list_item,
null);
holder = new ViewHolder();
holder.text1 = (TextView) convertView
.findViewById(R.id.country);
holder.checkBox = (CheckedTextView) convertView
.findViewById(android.R.id.checkbox);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txtcnt.setText(country[position]);
return convertView;
}
static class ViewHolder {
TextView txtcnt;
CheckBox checkBox;
}}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bokmarksjoks);
try {
db = (new DatabaseHelper(this)).getWritableDatabase();
} catch (IOException e) {
e.printStackTrace();
}
lv = (ListView) findViewById(R.id.list);
btn_delete = (Button) findViewById(R.id.delete);
btn_delete.setOnClickListener(this);
checkbox = (CheckBox) findViewById(R.id.checkbox);
txtname= (TextView) findViewById(R.id.body);
String name= pref.getString("name", "");
country= name.split(",");
lv.setAdapter(new EfficientAdapter(this));
lv.setItemsCanFocus(false);
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
lv.setOnItemClickListener(this);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.delete:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder .setMessage("Are you Sure want to delete checked country ?")
.setCancelable(false)
.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
// how to remove country
}
})
.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.setTitle("Delete Country");
alert.show();
case R.id.checkbox:
//What is the procedue in this section
default:
break;
}
}
public void onItemClick(AdapterView<?> pareant, View view, int position,
long id) {
try {
// I have trying this but could not proper output or only errors
SparseBooleanArray sp = lv.getCheckedItemPositions();
/*String str = "";
for (int i = 0; i < sp.size(); i++) {
str += country[sp.keyAt(i)] + ",";
}*/
} catch (Exception e) {
e.printStackTrace();
}}}
This is the only three country, actually, I have more then hundreds countries.
Delete items from tempCountry and then call adapter.notifyDataSetChanged().
Have a button on list and let it onclick feature in xml
like to get postion first
public void OnClickButton(View V){
final int postion = listView.getPositionForView(V);
System.out.println("postion selected is : "+postion);
Delete(postion);
}
public void Delete(int position){
if (adapter.getCount() > 0) {
//Log.d("largest no is",""+largestitemno);
//deleting the latest added by subtracting one 1
comment = (GenrricStoring) adapter.getItem(position);
//Log.d("Deleting item is: ",""+comment);
dbconnection.deleteComment(comment);
List<GenrricStoring> values = dbconnection.getAllComments();
//updating the content on the screen
this.adapter = new UserItemAdapter(this, android.R.layout.simple_list_item_1, values);
listView.setAdapter(adapter);
}
else
{
int duration = Toast.LENGTH_SHORT;
//for showing nothing is left in the list
Toast toast = Toast.makeText(getApplicationContext(),"Db is empty", duration);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
}
