[android-developers] removing items from listview and array list problem
I have this code i am used to pass an array list to another page and
show it as a listview. When the list shows up, i want to be able to
check an item and remove it at button click which will modify the
array.
public class Oppout extends Activity {
int selectedPosition;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.oppout);
final ListView lv2 = (ListView) findViewById
(R.id.custom_list_view);
lv2.setClickable(true);
lv2.setAdapter(new ArrayAdapterString(Oppout.this,
android.R.layout.simple_list_item_checked,
Entername.playerList));
lv2.setOnItemClickListener
(
new AdapterView.OnItemClickListener()
{
public void onItemClick(AdapterView adapterView,
View
view,int arg2, long arg3)
{
int selectedPosition =
adapterView.getSelectedItemPosition();
Toast.makeText(getBaseContext(), mu+
selectedPosition,
Toast.LENGTH_SHORT).show();
}
}
);
Button next = (Button) findViewById(R.id.button1);
next.setOnClickListener(new
View.OnClickListener() {
public void onClick(View view) {
//on click call the adapterview and
delete string at selected
position..this is my problem,
//i just don't know how to do it
int selectedPosition =
adapterView.getSelectedItemPosition();
adapterView.remove(player.SelectedPosition);
Intent myIntent = new Intent
(view.getContext(),
Callacab.class);
startActivityForResult(myIntent, 0);

Your variable player is never set to the text after clicking your button.

[android-developers] Re: EditText input into array
This is my new updated code, it prints out blank input in the
array...so why is it not storing my user input?
public class Screen2 extends Activity {
EditText txt1;
String player;
ArrayListString playerList = new ArrayListString();
/** Called when the activity is first created. **/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.screen2);
// edittext1 or textview1
txt1 = (EditText) findViewById(R.id.editText1);
player = txt1.getText().toString();
//add more items button
Button more = (Button) findViewById(R.id.button1);
more.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view){
if (txt1.getText().toString().length() !=0){
playerList.add(player);
}
System.out.println(playerList.toString());
}
});

That's still quite ambiguous. Read the link I gave you, then please try
again, with more detail. Explain what you are doing. Pretend we have no
knowledge of your problem since, you know, we don't.

// ---CheckBox 3---
final CheckBox checkBox3 = (CheckBox)
findViewById(R.id.checkBox3);
// ---CheckBox 4---
final CheckBox checkBox4 = (CheckBox)
findViewById(R.id.checkBox4);
Button next = (Button) findViewById(R.id.button1);
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if (checkBox.isChecked())
count++;
if (checkBox.isPressed())
count--;
if (checkBox2.isChecked())
count++;
if (checkBox2.isPressed())
count--;
if (checkBox3.isChecked())
count++;
if (checkBox3.isPressed())
count--;
if (checkBox4.isChecked())
count++;
if (checkBox4.isPressed())
count--;
