I have two list in android. One of them is title and the other is ID. I showed the title list in listView. Each title has it's own id. I want to get the id of the each title that I checked. how can I get the id of each title?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_remark);
context = getApplicationContext();
sh = new SchemaHelper(context);
// -- Display mode of the ListView
ListView listview= getListView();
// listview.setChoiceMode(listview.CHOICE_MODE_NONE);
// listview.setChoiceMode(listview.CHOICE_MODE_SINGLE);
listview.setChoiceMode(listview.CHOICE_MODE_MULTIPLE);
//-- text filtering
listview.setTextFilterEnabled(true);
final List<String> textList= new ArrayList<String>();
final List<String> idList= new ArrayList<String>();
Cursor c= sh.getAllRemark();
for(int i=0; c.moveToNext();i++){
String caption= c.getString(c.getColumnIndex(P_RemarkTable.REM_CAPTION.toString()));
String id= c.getString(c.getColumnIndex(P_RemarkTable.REM_ID.toString()));
textList.add(caption);
idList.add(id);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_checked, textList);
listview.setAdapter(adapter);
listview.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener(){
// idList.get(i).toString()
public void onItemClickListener(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getApplicationContext(),idList.get(i).toString() , Toast.LENGTH_SHORT).show();
// barrierID=Integer.parseInt(idList.get(i));
}
public void onItemChecked(AdapterView<?> adapterView, View view, int i, long l){
Toast.makeText(getApplicationContext(), idList.get(i).toString(), Toast.LENGTH_SHORT).show();
}
public void onListItemClick(AdapterView<?> adapterView, View view, int i, long l){
// super.onListItemClick(adapterView, view, i, l);
Toast.makeText(getApplicationContext(),idList.get(i).toString(), Toast.LENGTH_SHORT).show();
}
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getApplicationContext(), idList.get(i).toString(), Toast.LENGTH_SHORT).show();
// barrierID=Integer.parseInt(idList.get(i));
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
// do nothing
}
});
}
}
}
Non of this method works.
What should I do?

I was looking to filter a listView by an editText.
My ListView is populate by an ArrayString, and when I filter it everything goes right. But I have a problem to recognize the element clicked. When I filter the listView and I click on the item filtered I want to have the number of the row in the original arrayString in order to make an Intent. Whit my code when I click the item in the filtered arrayString the row is 0 and it's not correct. If I search "Anche Se Pesa" I want to return the row 2 like the position in the original ArrayString.
<string-array name="titoli">
<item>An Val Dondona</item>
<item>Anche Mio Padre</item>
<item>Anche Se Pesa</item>
<item>Andremo In Francia</item>
<item>Aprite Le Porte</item>
<item>Arda Berghem</item>
<item>Ascoltate Amici Cari</item>
<item>Ave, O Vergine</item>
<item>Aver na Figlia Sola Soletta</item>
<item>Ancora sti quatro</item>
<item>Andouma Prou</item>
</string-array>
Here Is the code
public class activity_titoli extends AppCompatActivity {
Button btt_backHome;
ListView lV_titoli;
EditText eT_search;
private ArrayAdapter<CharSequence> adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_titoli);
btt_backHome = (Button) findViewById(R.id.btt_backHome);
lV_titoli = (ListView) findViewById(R.id.lV_titoli);
eT_search = (EditText) findViewById(R.id.eT_search);
adapter = ArrayAdapter.createFromResource(this, R.array.titoli, android.R.layout.simple_list_item_1);
lV_titoli.setAdapter(adapter);
final Intent to_Home = new Intent (this , Activity_Main.class);
eT_search.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
#Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
(activity_titoli.this).adapter.getFilter().filter(arg0);
}
});
btt_backHome.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(to_Home);
}
});
lV_titoli.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Log.e("Element: " , Integer.toString(i));
}
});
}
}
Try this code :
lV_titoli.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Resources res = getResources();
List<CharSequence> list = Arrays.asList(res.getStringArray(R.array.titoli));
Log.e("Element: " , Integer.toString(list.indexOf(adapter.filgetItem(i))));
}
});
Hope this helps
I want to set text from selected item from spinner to textview, But when i tried to do application craches. Can any one help me .
public class MainActivity extends AppCompatActivity {
TextView txt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txt=(TextView) findViewById(R.id.txt1) ;
ArrayList<ItemData> list=new ArrayList<>();
list.add(new ItemData("Cash",R.drawable.paymentcashnew));
list.add(new ItemData("Paytm",R.drawable.paymentpaytmnew));
Spinner sp=(Spinner)findViewById(R.id.select_cash);
String result = sp.getSelectedItem().toString();
txt.setText(result);
SpinnerAdapter adapter=new SpinnerAdapter(this,
R.layout.spinner,R.id.txt,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp.setAdapter(adapter);
}
}
sp.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String result = sp.getSelectedItem().toString();
txt.setText(result);
}
});
This may help Frnd.
spinner has no "getSelectedItem". https://developer.android.com/reference/android/widget/Spinner.html https://developer.android.com/guide/topics/ui/controls/spinner.html
and here's how you get the text-value of the selected row: https://stackoverflow.com/a/15545909/3022387
spin.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String imc_met=spin.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
Implement spinner.setOnItemClickListener and then find text inside that method like this.
spinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String result = sp.getSelectedItem().toString();
txt.setText(result);
}
});
You can't get selected Item before setting adapter.Try this below code
public class MainActivity extends AppCompatActivity {
final TextView txt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txt=(TextView) findViewById(R.id.txt1) ;
ArrayList<ItemData> list=new ArrayList<>();
list.add(new ItemData("Cash",R.drawable.paymentcashnew));
list.add(new ItemData("Paytm",R.drawable.paymentpaytmnew));
Spinner sp=(Spinner)findViewById(R.id.select_cash);
SpinnerAdapter adapter=new SpinnerAdapter(this,
R.layout.spinner,R.id.txt,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp.setAdapter(adapter);
sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Object item = parent.getItemAtPosition(position);
String result = sp.getSelectedItem().toString();
txt.setText(result);
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
}
I have a spinner with ten numbers 0-10 and I if someone picks a number I want him not to be able to pick the same value again. So inside ItemSelected I do the following with no result
#Override
public void onItemSelected(AdapterView<?> adapter, View v, int position, long id) {
// On selecting a spinner item
if (position > 0 && position!=tempPosition)
{
TeamSpinnerNumber = adapter.getItemAtPosition(position).toString();
tempPosition = position
}
}
Check this i worked out for you may it help you.
public class MainActivity extends AppCompatActivity {
ArrayList<String> mStrings;
ArrayAdapter<String> mStringArrayAdapter;
Spinner mSpinner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSpinner = (Spinner) findViewById(R.id.spinner);
mStrings = new ArrayList<String>() {{
add("None");
add("one");
add("two");
add("three");
}};
mStringArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mStrings);
mSpinner.setAdapter(mStringArrayAdapter);
mSpinner.setSelection(0);
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String string = parent.getItemAtPosition(position).toString();
if (!string.equals("None"))
removeThisFromSpinner(string);
mSpinner.setSelection(0);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
private void removeThisFromSpinner(String s) {
mStrings.remove(s);
mStringArrayAdapter.notifyDataSetChanged();
}
}
try this, hope it helps :
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.i(TAG, "onItemSelected: "+position);
//checking the position of the selected spinner item, if the previous position is not the same then do something here
if(position>0 && position!=myPosition){
}
myPosition = position;
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
and don't forget to add global variable to the class :
int myPosition = 999; // the non existed position make it global variable
I guess this is simple.
I want to toast the text in the rows when I click on it. And here is my code:
public class AndroidSQLite extends Activity { private SQLiteAdapter
mySQLiteAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView listContent = (ListView)findViewById(R.id.contentlist);
mySQLiteAdapter = new SQLiteAdapter(this);
mySQLiteAdapter = new SQLiteAdapter(this);
mySQLiteAdapter.openToRead();
Cursor cursor = mySQLiteAdapter.queueAll();
startManagingCursor(cursor);
String[] from = new String[]{SQLiteAdapter.KEY_NOME};
int[] to = new int[]{R.id.text};
SimpleCursorAdapter cursorAdapter =
new SimpleCursorAdapter(this, R.layout.row, cursor, from, to);
listContent.setAdapter(cursorAdapter);
mySQLiteAdapter.close();
}
}
Thank You!
just write down
listContent.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View arg1,
int position, long id) {
Log.i("get ItemIDPosition",
"" + adapter.getItemIdAtPosition(position));
Log.i("get ItemATPosition", "" + adapter.getItemAtPosition(position));
}
});
You can use
listContent.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
}
});
Like this:
listContent.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String item = ...;
Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();
}
});
Try this code for Item click
listContent.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String text = <Get Your from database is here in this string>;
Toast.makeText(getBaseContext(), text, Toast.LENGTH_LONG).show();
}
});
Use onitemclick evetn and not onclick.
listview.setOnItemClickListener(...);
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
arg2 is the index in the list.
I have a Listview in my project for which i want to find out the string value of the selected item in the listview.
Here is a simple Examlple.
#Override
protected void onListItemClick(ListView l, View v, int position, long thisID)
{
super.onListItemClick(l, v, position, thisID);
// Get the item that was clicked
Object o = this.getListAdapter().getItem(position);
String keyword = o.toString();
}
From your Activity
public class ExampleActivity extends Activity {
String str_arr[] = {"A", "B", "C"};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView listView = (ListView) findViewById(R.id.listView1);
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, str_arr));
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position,
long id) {
// TODO Auto-generated method stub
Object o = adapter.getItemAtPosition(position);
String str_text = o.toString();
Intent intent = new Intent(ExampleActivity.this, NewExample.class);
intent.putExtra("StrValue", str_text);
startActivity(intent);
}
});
}
}
