Editable ListView Items
I want to edit my items ListView
. eg; I have an item ListView
that I clicked on this item and add string value
using edit text
after that, I click on that item again and add a new one string value
next to the previous one string value
and again again again. When I click this item, I want to edit this list. How do I do it?
Java Source Package:
public class MainActivity extends Activity {
TextView tvDers;
EditText etDers, etDersSaati;
EditText etNot;
LinearLayout LayoutDers;
ArrayAdapter<String> adapter;
ListView list;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btnDersEkle = (Button) findViewById(R.id.btnDersEkle);
list = (ListView) findViewById(R.id.listView1);
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1);
etDers = new EditText(MainActivity.this);
//Dialog
AlertDialog.Builder build = new AlertDialog.Builder(MainActivity.this);
build.setTitle("Ders Ekle");
build.setView(etDers);
build.setPositiveButton("Tamam", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
adapter.add(etDers.getText().toString());
}
});
list.setAdapter(adapter);
final AlertDialog alertDers = build.create();
btnDersEkle.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
alertDers.show();
}
});
}
}

Storing the values of elements in the Collection order. Install this collection to the adapter. Add and remove these values after the call notifyDataSetChanged
for the adapter.
Try it.
listView.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
String item = (String) parent.getItemAtPosition(int position);
item += "YourText";
ArrayAdapter adapter = (ArrayAdapter ) parent.getAdapter();
adapter.insert(item, position);
}
Sorry, but now I cannot verify this code. Therefore, I cannot say for sure that this is correct. Try different options and you will get it.
UPDATE In the clickListener dialog, you can try this:
@Override
public void onClick(DialogInterface dialog, int which) {
ArrayAdapter adapter = (ArrayAdapter ) listView.getAdapter();
String item = (String) listView.getSelectedItem();
item += "YourText";
adapter.insert(item, position);
}
