I am making a simple planner app, with one xml and one activity. Here is MainActivity, where basically I take editText input, turn it into a listView item with button onClick, and save it. The only probmlem is my alert dialog for when you want to delete an item has an error - it won't recognize the word "position". I feel like it's just some dumb typo..? Thank you.

adapter.add(dataSet);
adapter.notifyDataSetChanged();
}
}`
Try this way :
ArrayAdapter<String> adapter = (ArrayAdapter<String>)getListView().getAdapter();
adapter.remove(adapter.getItem(info.position));
adapter.notifyDataSetChanged();
May be, this needed.... adapter.notifyDataSetChanged(); when remove..
alertDialogBuilder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
adapter.remove(adapter.getItem(position));
adapter.notifyDataSetChanged();
}
});
The position variable needs to be final if you want to access it there.
Do it as follows:
final int p = position; // just before setPositiveButton
alertDialogBuilder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
adapter.remove(adapter.getItem(p));
}
});

You can use textwatcher for this , it will change your name String every time when text is changing in EditText field.
et1.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable s) {
name = edtName.getText().toString();
//it will change your name String every time when text is changing in EditText fiels
}
});
Hope this is what you want.
Its rather simple. On vb.net is just this... c# is only slightly different.
Dim b As New Button
b.text = "New Button"
b.Location = New Point(0, 0)
AddHandler b.Click, AddressOf handle_click
Private Sub handle_click(sender As Object, e As EventArgs)
'code here to react to the buttons click.
End Sub

Controls in Java
I am trying to make a drop down menu that changes the text of a text view to "Player Selected: " and then a player selected from the drop down menu. However when i test the app on android, i can click a spinner item but it doesn't register anything. The textview doesn't change, and it doesn't log anything as if it wasn't registering the click listener at all. Here's my code
package com.example.buddyfizzturtles.stattracker;
import android.app.Dialog;
import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.Toast;
import java.util.*;
import android.widget.AdapterView.OnItemSelectedListener;
public class MainActivity extends AppCompatActivity {
EditText input;
Button showBtn;
TextView showPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Players p = new Players();
// Pop-Up Dialog
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Enter Name");
builder.setIcon(R.drawable.basketball);
builder.setMessage("Enter a name for your player");
input = new EditText(this);
builder.setView(input);
//Set Positive Button
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
String text = input.getText().toString();
Player x = new Player(text);
p.addPlayer(x);
Toast.makeText(MainActivity.this, "Added " + text + " to your player list", Toast.LENGTH_SHORT).show();
}
});
//Set Negative Button
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
//Create Builder
final AlertDialog ad = builder.create();
//Button
showBtn = (Button) findViewById(R.id.addPlayerButton);
showBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ad.show();
}
});
//Spinner Items
Spinner dropNames = (Spinner) findViewById(R.id.choosePlayer);
dropNames.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
Log.d("CLICKED:", "Successful Click");
showPlayer = (TextView) findViewById(R.id.showPlayer);
showPlayer.setText("Player Selected: " + );
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
// your code here
}
});
ArrayAdapter<Player> adapter = new ArrayAdapter<Player>(this, android.R.layout.simple_spinner_item, p.returnList());
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dropNames.setAdapter(adapter);
}
}
You can try this. Let's see if it resolves
Spinner spinner=(Spinner)findViewById(R.id.spinner);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
Log.d("CLICKED:", "Successful Click");
showPlayer = (TextView) findViewById(R.id.showPlayer);
showPlayer.setText("Player Selected: " + );
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
Hope this helps
If the spinner is loading data, then I think this will help you (It's good to define showPlayer outside the listener).
Spinner dropNames = (Spinner) findViewById(R.id.choosePlayer);
TextView showPlayer = (TextView) findViewById(R.id.showPlayer);
dropNames.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(
AdapterView<?> parent, View view, int position, long id) {
showPlayer.setText("Player Selected: " + String.valueOf(dropNames.getSelectedItem());
}
#Override
public void onNothingSelected(AdapterView<?> parent)
{
}
});

#Override

final EditText tt = (EditText)findViewById(R.id.editText);
final ListView lv = (ListView)findViewById(R.id.listView1);
Button br = (Button)findViewById(R.id.button);
add1 = tt.getText().toString();
adapter=new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,listss);
lv.setAdapter(adapter);
listss.add(add1);
adapter.notifyDataSetChanged();
br.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View ss = LayoutInflater.from(MainActivity.this).inflate(R.layout.textt,null);
final AlertDialog.Builder builderDialog = new AlertDialog.Builder(MainActivity.this);
builderDialog.setView(ss)
.setPositiveButton("Print", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
listss.add(add1);
adapter.notifyDataSetChanged();
}
}).setNegativeButton("Cancel", null)
.setCancelable(false);
AlertDialog alert = builderDialog.create();
alert.show();
}
});
}
}
Try this code below (for getting edittext data):
br.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View ss = LayoutInflater.from(MainActivity.this).inflate(R.layout.textt,null);
final AlertDialog.Builder builderDialog = new AlertDialog.Builder(MainActivity.this);
builderDialog.setView(ss)
.setPositiveButton("Print", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
EditText et = (EditText) ss.findViewById(E.id.editText);
listss.add(et.getText().toString());
adapter.notifyDataSetChanged();
}
}).setNegativeButton("Cancel", null)
.setCancelable(false);
AlertDialog alert = builderDialog.create();
alert.show();
}
});
Here is the method in which i call on Button button.setOnClickListener
public void saveNote(View view){
final Dialog dialog = new Dialog(MainActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.add_new_note_layout);
mTitle = (EditText)dialog.findViewById(R.id.titleID);
mMessage = (EditText)dialog.findViewById(R.id.messageID);
save = (Button)dialog.findViewById(R.id.saveBtn);
setFilePathll();
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int titleLength = mTitle.getText().length();
if(titleLength != 0){
String title = mTitle.getText().toString();
String msg = mMessage.getText().toString();
helper.addNote(title, mFilePath, msg);
dialog.dismiss();
}
else
{
Toast.makeText(MainActivity.this,"Empty Message is not valid",Toast.LENGTH_LONG).show();
}
}
});
dialog.show();
}
Here helper.addNote(title, mFilePath, msg); is the method which i declared in the database helper class to insert data.
you Should use RecyclerView for what you want instead of using 'ListView'
There is an error in 'return view' at listview.setOnItemLongClickListener method. The error says cannot return a value from a method with void result type. I am trying to create an alert dialog where it will notify the user whether it wants to delete.

You are trying to return a View from your Activity's onCreate() method.
#Override
protected void onCreate(Bundle savedInstanceState) {
LayoutInflater inflater = LayoutInflater.from(Record.this);
View view = inflater.inflate(R.layout.activity_record, null);
//...
return view;
}
As you can see, onCreate() in an Activity has a void return type, meaning you shouldn't be returning anything in this method.
From the looks of your code, you are attempting to use this layout as the Activity's layout, but you are confusing the View inflation code with that used in a Fragment's onCreateView() method, which does indeed require you to return a View.
In an Activity, you need to call setContentView() to set the layout. You can either set the layout using the resource ID via setContentView(R.layout.activity_record), or if you want to inflate the View yourself you can call setContentView(view).
The call return view is actually located in onCreate. The function onCreate is declared to return nothing (void). Therefore, you cannot return an instance of View. You just have to remove that line or replace it with return; Also, onItemLongClick must return a boolean. So you can't move return view there either.
I have a ListView which has more rows in it. Inside of rows I have two LinearLayouts (deleteItem and editItem) which has setOnClickListener on them. When I'm trying to click on deleteItem or editItem it works only at the second touch, i don't know why.. I've read some answers on stackoverflow but I couldn't find one answer to fix my problem..

Your problem might be caused by the way your program executes. You first thread your adapter initialization, and then your main thread starts attaching onclick listeners before your adapter initialization finishes. This means your listview will have a click listener but not the items in the adapter, and when you click the listview once
new GetMyCurrencyResults().execute(new MyCurrencyConnector());
this fires off in your DeleteCurrencyTask and sets the adapter again. To fix this try putting setOnClick initializaion in the post execute of your
private class GetMyCurrencyResults extends AsyncTask<MyCurrencyConnector,Void,JSONArray>{
I believe I realized why the event of deleteItem and editItem is called only on second click, because deleteItem and editItem clickListeners are atached only when getAllMyCurrencyListView.setOnItemClickListener (when I click on row) is called not when the code is loaded. So I guess I have to find another way to make these events
