I have a custom dialog with one editText view and two buttons ok and cancel. I have a custom list view displaying some rows of data fetched from database. When the user clicks on the row of the list view, custom dialog box is shown to the user to edit the selected row. What i want to do is to be able to pass the object binded with the selected row to the dialog box so that i could display the data being edited.
Here is my activity class:
public class TestDatabaseActivity extends ListActivity {
private CommentsDataSource datasource;
private CommentAdapter adt;
static final int CUSTOM_DIALOG_ID = 0;
private TextView dialog_editComment;
private EditText dialog_txtEditComment;
private Button dialog_btnOk, dialog_btnCancel;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
datasource = new CommentsDataSource(TestDatabaseActivity.this);
datasource.open();
getList();
}
private void getList()
{
List<Comment> values = datasource.getAllComments();
adt=new CommentAdapter(TestDatabaseActivity.this,R.layout.comment_row,values);
setListAdapter(adt);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
CommentAdapter adapter= (CommentAdapter) getListAdapter();
final Comment cmt = adapter.mListComment.get(position);
System.out.println(cmt.getId()+cmt.getComment());
//cmt is the object which i want to pass to my dialog
showDialog(CUSTOM_DIALOG_ID);
}
private Button.OnClickListener customDialog_UpdateOnClickListener = new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
//save the value and update list
}
};
private Button.OnClickListener customDialog_DismissOnClickListener
= new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
dismissDialog(CUSTOM_DIALOG_ID);
}
};
@Override
protected Dialog onCreateDialog(int id) {
// TODO Auto-generated method stub
Dialog dialog = null;;
switch(id) {
case CUSTOM_DIALOG_ID:
dialog = new Dialog(TestDatabaseActivity.this);
dialog.setContentView(R.layout.comment_edit_dialog);
dialog.setTitle("Edit");
dialog_editComment = (TextView)dialog.findViewById(R.id.editComment);
dialog_txtEditComment = (EditText)dialog.findViewById(R.id.txtComment);
dialog_btnOk = (Button)dialog.findViewById(R.id.btnOk);
dialog_btnCancel = (Button)dialog.findViewById(R.id.btnCancel);
dialog_btnOk.setOnClickListener(customDialog_UpdateOnClickListener);
dialog_btnCancel.setOnClickListener(customDialog_DismissOnClickListener);
break;
}
return dialog;
}
}
