Set cursor position using setSelection on AutoCompleteTextView which is dynamically generated

I am working on a project which uses a TableLayout, and the user can add a new row to the table layout. Each new row is inflated as a new view and then the view is added to the table layout. One of the controls within the row is an AutoCompleteTextView.
The user can start typing into the AutCompleteTextView and then select one of the items in the suggestion list, when the user selects the item, the selected item is added to the text box as expected, but I want to then set the cursor position as the user can then change the value of the text. For example, the selected item might be sometext() but they can amend the text after selecting it to become sometext(25), so I am trying to set the position of the cursor within the brackets.
This is working fine for one AutoCompleteTextView in the layout but I can't figure out how to do it when its dynamically generated.
I'm finding the AutoCompleteTextView from the inflated layout and creating a set on item click listener, and using the view parameter in the OnItemClick function to ensure I am using the correct view that triggered the event handler, but on the setSelection I am getting an exception java.lang.ClassCastException: android.support.v7.widget.AppCompatTextView cannot be cast to android.widget.AutoCompleteTextView
Below is the code I am using:
private void addRow()
{
TableRow row = (TableRow)LayoutInflater.from(this).inflate(R.layout.create_table_column_row, createTable, false);
txtColumnName = row.findViewById(R.id.txtColumnName);
txtDataType = row.findViewById(R.id.txtDataType);
txtDataType.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
txtDataType.showDropDown();
}
});
txtDataType.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
String selectedItem = parent.getItemAtPosition(position).toString();
//Check if the string has a ( and if so, set the cursor to be just after it so the user can enter the size
int bracketPos = selectedItem.indexOf("(");
if (bracketPos > 0)
{
//Crashes on this line
((AutoCompleteTextView)view).setSelection(bracketPos+1);
}
}
});
List<String> datatypes = Arrays.asList(getResources().getStringArray(R.array.table_datatypes));
datatypeAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, datatypes);
txtDataType.setAdapter(datatypeAdapter);
rowViews.add(row);
createTable.addView(row);
}
I tried casting the view to AppCompatTextView but then this doesn't have the setSelection() method.

The view in onItemClick() is the AppCompatTextView that is clicked in the drop down box for the AutoCompleteTextView. That is why you can't cast it.
Since you have multiple AutoCompleteTextViews, use a focus change listener to capture which AutoCompleteTextView is being addressed by the user. You can then use that value to set the position of the cursor.
private AutoCompleteTextView textView;
private AutoCompleteTextView mAuto;
textView.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
mAuto = (AutoCompleteTextView) v;
}
});
textView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d("MainActivity", "<<<<onItemClicked");
int bracketPos = textView.getText().toString().indexOf("(");
if (bracketPos > 0) {
mAuto.setSelection(bracketPos + 1);
}
}
});
I believe that the AutoCompleteTextView is already populated when this method is called, so you could just search for ( within that field.
Here is a slightly different way. After
txtDataType = row.findViewById(R.id.txtDataType);
add
txtDataType.setOnClickListener(new View.OnClickListener() {
private AutoCompleteTextView mAutoView;
#Override
public void onClick(View v) {
mAutoView = (AutoCompleteTextView) v;
mAutoView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d("MainActivity", "<<<<onItemClicked");
int bracketPos = mAutoView.getText().toString().indexOf("(");
if (bracketPos > 0) {
mAutoView.setSelection(bracketPos + 1);
}
}
});
}
});
You can delete your other listeners.

calling remove from custom adapter always removes last item

I have implemented a custom adapter and listItemView. The adapter sets an onlclick listener to a button that is on the listItemView. The onclick listener simply calls a private method I have in the adapter and passes it the position of the item to be removed. I know the position is correct because the database removes the proper item. I have found similar questions but have not been able to adapt the answers to work for me. Ideas and thoughts are greatly appreciated. Thanks.
Here is the full adapter class
public class FoodListAdapter extends ArrayAdapter<FoodListItem> {
//private
private int type;
public FoodListAdapter(Context context, ArrayList<FoodListItem> _objects) {
super(context, 0, _objects);
type = 0;
}
public FoodListAdapter(Context context, ArrayList<FoodListItem> _objects, int _type) {
super(context, 0, _objects);
type = _type;
}
#Override
public View getView(int position, View reusableView, ViewGroup parent)
{
//Cast the reusable view to a listAdpaterItemView
FoodListItemView listItemView = (FoodListItemView) reusableView;
//Check if the listAdapterItem is null
if(listItemView == null)
{
//If it is null, then create a view.
listItemView = FoodListItemView.inflate(parent, this, type);
}
if (type == 2)
{
Button deleteButton = (Button) listItemView.findViewById(R.id.listItemViewDeleteBTN);
deleteButton.setTag(new Integer(position));
}
//Now we need to set the view to display the data.
listItemView.setData(getItem(position));
return listItemView;
}
}
Here is a portion of my code used in fragment. Note that I have a private variable decalred in the class for listAdapter, though I don't think I need that.
private void displayListForDate(Calendar _date)
{
//get the list view
ListView listView = (ListView) getView().findViewById(1);
//Clear the listview by removing the listadapter and setting it to null.
//listView.setAdapter(null);
//First we must get the items.
Global global = (Global) getActivity().getApplicationContext();
DietSQLiteHelper database = global.getDatabase();
//Create a list to hold the items we ate. This list will then be added to the listView.
final ArrayList<FoodListItem> consumedList;
//Add the items to the array.
consumedList = database.getConsumed(_date.getTimeInMillis());
//Create an adapter to be used by the listView
listAdapter = new FoodListAdapter(getActivity().getBaseContext(), consumedList, 2);
//Add the adapter to the listView.
listView.setAdapter(listAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
consumedList.remove(position);
listAdapter.notifyDataSetChanged();
}
});
}

If you didn't implement "equals" method of FoodListItem, try to implements it.

I would suggest,
that you just update the underlying data, in your case its ArrayList<FoodItems>.
In your Adapter make this simple method and change :
private List<FoodListItem> myList = new ArrayList<FoodListItem>();
public FoodListAdapter(Context context, List<FoodListItem> myList) {
super(context, 0, myList);
type = 0;
this.myList = myList;
}
public FoodListAdapter(Context context, List<FoodListItem> myList, int _type) {
super(context, 0, myList);
type = _type;
this.myList = myList;
}
// Also update your getView() method to use myList!
#Override
public View getView(int position, View reusableView, ViewGroup parent)
{
...
listItemView.setData(myList.get(position));
public void removeItem(int positio){
if(myList != null){
myList.remove(position);
}
}
And then in class, you are creating the adapter (Activity/Fragment), just call the method.
// Update the underlying ArrayAdapter
adapter.removeItem(position);
// Notify the adapter, the data has changed
adapter.notifyDataSetChanged();
Also, you shouldnt open connection to your SQLiteDatabase on UI thread, because you are blocking it. You never know, how fast is the reading from disk going to be. If it takes too long, user can think, that your application froze and therefore, he leaves, which you dont want. I would suggest to use AsyncTask, you will find a lot of examples.

I went through and cleaned up my code and it now works, here is the working code. I really don't know exactly the difference other than I updated the IDs that I was using to assign and get views. If anyone can explain the cause for the issue I was having I would appreciate it.
Here is the snippet from my fragment where I create the list view and assign an adapter.
private void displayListForDate(Calendar _date)
{
//get the list view
ListView listView = (ListView) getView().findViewById(R.id.listView);
//Clear the listview by removing the listadapter and setting it to null.
//listView.setAdapter(null);
//First we must get the items.
Global global = (Global) getActivity().getApplicationContext();
DietSQLiteHelper database = global.getDatabase();
//Create a list to hold the items we ate. This list will then be added to the listView.
ArrayList<FoodListItem> consumedList;
//Add the items to the array.
consumedList = database.getConsumed(_date.getTimeInMillis());
//Create an adapter to be used by the listView
listAdapter = new FoodListAdapter(getActivity().getBaseContext(), consumedList, 2);
//Add the adapter to the listView.
listView.setAdapter(listAdapter);
}
and here is my adapter class.
public class FoodListAdapter extends ArrayAdapter<FoodListItem>
{
//private
private int type;
public FoodListAdapter(Context context, ArrayList<FoodListItem> _objects) {
super(context, 0, _objects);
type = 0;
}
public FoodListAdapter(Context context, ArrayList<FoodListItem> _objects, int _type) {
super(context, 0, _objects);
type = _type;
}
#Override
public View getView(int position, View reusableView, ViewGroup parent)
{
//Cast the reusable view to a listAdpaterItemView
FoodListItemView listItemView = (FoodListItemView) reusableView;
//Check if the listAdapterItem is null
if(listItemView == null)
{
//If it is null, then create a view.
listItemView = FoodListItemView.inflate(parent, type);
}
if (type == 2)
{
Button deleteButton = (Button) listItemView.findViewById(R.id.listItemViewDeleteBTN);
deleteButton.setTag(new Integer(position));
deleteButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Integer tag = (Integer) view.getTag();
deleteItem(tag.intValue());
}
});
}
//Now we need to set the view to display the data.
listItemView.setData(getItem(position));
return listItemView;
}
private void deleteItem(int position)
{
FoodListItem item = getItem(position);
Global global = (Global) getContext().getApplicationContext();
DietSQLiteHelper database = global.getDatabase();
database.removeConsumed(item.getID());
remove(getItem(position));
}
}

Custom SimpleCursorAdapter - refresh, update DB

My issue today is related to a custom SimpleCursorAdapter I've implemented. Here are my activities onCreate() and the custom SimpleCursorAdapter :
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
customSharedPreference = getSharedPreferences("myCustomSharedPrefs", Activity.MODE_PRIVATE);
editor = customSharedPreference.edit();
setContentView(R.layout.activity_1);
op = new OperationsClass(getApplicationContext());
op.open();
Cursor cursor = op.getList();
startManagingCursor(cursor);
String[] columns = new String[] { "AAA", "BBB", "CCC"};
int[] to = new int[] { R.id.entry_aaa,R.id.entry_bbb, R.id.entry_ccc};
MyCursorAdapter mAdapter = new MyCursorAdapter(this, R.layout.custom_entry, cursor, columns, to);
this.setListAdapter(mAdapter);
op.close();
}
OperationsClass manages a database and the getList() function returns a cursor of the entries.
public class MyCursorAdapter extends SimpleCursorAdapter{
private Context context;
private MyCursorAdapter here = this;
private int layout;
public MyCursorAdapter (Context context, int layout, Cursor c, String[] from, int[] to) {
super(context, layout, c, from, to);
this.context = context;
this.layout = layout;
}
#Override
public View newView(final Context context, Cursor cursor, ViewGroup parent) {
Cursor c = getCursor();
final LayoutInflater inflater = LayoutInflater.from(context);
View v = inflater.inflate(layout, parent, false);
int col1 = c.getColumnIndex("aaa");
String name1 = c.getString(col1 );
int col2 = c.getColumnIndex("bbb");
String name2 = c.getString(col2 );
int col3 = c.getColumnIndex("ccc");
int name3 = c.getInt(col3 );
final TextView text1 = (TextView) v.findViewById(R.id.entry_aaa);
final TextView text2 = (TextView) v.findViewById(R.id.entry_bbb);
final TextView text3 = (TextView) v.findViewById(R.id.entry_ccc);
text1.setText(name);
text2.setText(name2);
if (name3 == 0)
text3.setText("Not checked");
else {
text3.setText("Checked");
text3.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
text3.setText("Not checked");
// Here I would like to update my DB using
// OperationsClass and the SharedPrefs,
// and refresh the ListView with the new
// text value.
}
});
}
}
return v;
}
#Override
public void bindView(View v, final Context context, Cursor c) {
// Same operations as higher
}
}
Basically what I want to achieve is to refresh the ListView when the users clicks on the third column, which means its value changes (has been clicked or has not been). In the same time I wish to update the DB and the SharedPreferences(I could create a new object of both classes and recover from the application context, but that seems pretty heavy).
I also wish to know if there is a way to trigger one of the implemented methods in one activity when an AlertDialog has been opened (in the same app, I actually want to add an element to my database through an AlertDialog and make the Activity that popped it up retrieve a new cursor and refresh its List).

"Basically what I want to achieve is"
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
// if (the id of selected view matches what you want) {
boolean checked;
if (text3.getText().toString() == "checked") {
boolean checked = true;
} else {
boolean checked = false;
}
op.updateRead(id, checked);
refreshCursorAdapter();
setSharedPrefs();
// }
"to refresh the ListView when the users clicks on the 3rd column, which means its value changes (has been clicked or has not been)."
private void refreshCursorAdapter() {
Cursor cursor = op.getList();
mAdapter.changeCursor(cursor);
}
"In the same time I wish to update the DB"
private boolean updateRead(long rowId, boolean checked) {
ContentValues args = new ContentValues();
if (checked) {
args.put("read", "1");
} else {
args.put("read", "0");
}
return db.update(DB_TABLE, args, "_id =" + rowId, null) > 0;
}
"and the SharedPrefereces"
private void setSharedPrefs() {
SharedPreferences settings = getSharedPreferences("MYPREFS", 0);
SharedPreferences.Editor editor = settings.edit();
if (checked) {
editor.putBoolean("read", false);
} else {
editor.putBoolean("read", true);
}
editor.commit();
}
"I also wish to know if there is a way to trigger one of the implemented methods in one activity when an AlertDialog has been opened"
Quite honestly i don't understand what the mystique behind this one is. The process would involve copying and pasting the same code else to some other event.

Basically what I want to achieve is to refresh the ListView when the
users clicks on the 3rd column, which means its value changes (has
been clicked or has not been). In the same time I wish to update the
DB and the SharedPrefereces (I could create a new object of both
classes and recover from the application context, but that seems
pretty heavy).
First of all, you shouldn't be implementing that logic in the newView method because that method will not be called for every row due to the recycling. The newView should be used only to build a new row view and nothing more. Use the bindView method for any row logic.
Regarding the code in the onClick method I don't see where do you have problems. Update the database based on your logic and then query again the database for a Cursor with the new data and then use swapCursor() to update the adapter with the new values. This should work but it's not the recommended way mainly because you're doing every database operation on the main UI thread. Don't use the startManagingCursor method because this method runs the queries on the main UI thread, instead have a look at implementing a Loader in your activity to load data off the main UI thread. With a Loader you'll update the database values and then simply restart the Loader to update the list.
I also wish to know if there is a way to trigger one of the
implemented methods in one activity when an AlertDialog has been
opened (in the same app, I actually want to add an element to my
database through an AlertDialog and make the Activity that poped it up
retrieve a new cursor and refresh its List).
You're not saying anything about how you show that AlertDialog. If you want to update the list after you add the new element then use the listeners for the AlertDialog's buttons and the same code as above.

Android Spinners in ListView, do I have to use a ViewHolder?

I have an issue with Spinners in a ListView. I have a ListView with a CheckBox, a label, and two Spinners. The Spinner are populated from SQLite and that is working fine. I am not using the ViewHolder method because so far when the ListView row is clicked the CheckBoxes are checked or unchecked and the change is immediately saved to the database. When the row is checked the Spinners are made visible but are not visible when the row is not checked.
So the issue that I haven't managed to find a solution for is that I have no idea how to get the actual Spinner or even get the ListItem row that the clicked Spinner is on. The Activity extends ListActivity. Anyone know a way I can do this without using a ViewHolder or do I have to use a ViewHolder?
Here is the code that declares and populates the ListView:
mSsCursor = mDbHelper.fetchAllSsPlaylistSs(mPlId);
startManagingCursor(mSsCursor);
String[] from = new String[]{"pl_selected", BTDbAdapter.KEY_NAME, BTDbAdapter.KEY_NAME2};
int[] to = new int[]{R.id.pl_selected, R.id.name, R.id.name2};
mAllSs = new SimpleCursorAdapter(this, R.layout.pl_edit_ss_row, mSsCursor, from, to);
mAllSs.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
//custom handling of setting the value
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
if(columnIndex == 3) {
ViewGroup row = (ViewGroup)view.getParent().getParent();
mSId = cursor.getInt(0);
if (cursor.getInt(3) > 0) {
mCheckBox = (CheckBox) row.findViewById(R.id.pl_selected);
mCheckBox.setChecked(true);
mTSpin = (Spinner) row.findViewById(R.id.pl_t_spin);
mMSpin = (Spinner) row.findViewById(R.id.pl_m_spin);
mtvT = (TextView) row.findViewById(R.id.pl_t);
mtvM = (TextView) row.findViewById(R.id.pl_m);
mTSpin.setVisibility(View.VISIBLE);
mtvT.setVisibility(View.VISIBLE);
mMSpin.setVisibility(View.VISIBLE);
mtvM.setVisibility(View.VISIBLE);
//set the values in the t spinner
PopulateTSpinner(cursor.getInt(4));
//set the values in the m spinner
PopulateMSpinner(cursor.getInt(5));
}
else {
mCheckBox = (CheckBox) row.findViewById(R.id.pl_selected);
mCheckBox.setChecked(false);
mTSpin = (Spinner) row.findViewById(R.id.pl_t_spin);
mMSpin = (Spinner) row.findViewById(R.id.pl_m_spin);
mtvT = (TextView) row.findViewById(R.id.pl_t);
mtvM = (TextView) row.findViewById(R.id.pl_m);
mTSpin.setVisibility(View.GONE);
mtvT.setVisibility(View.GONE);
mMSpin.setVisibility(View.GONE);
mtvM.setVisibility(View.GONE);
}
return true;
}
return false;
}
});
setListAdapter(mAllSs);
Thanks.

I don't know if I understood your question: If your app flow is:
show a list of data(CheckBox + TextView(Spinners hidden)) ->
user clicks a row(the Spinners appear for that row with(individual) data) ->
user selects something in those Spinners->
save that selection in the database
then I think you should go with a custom adapter and take care yourself of the row creation + data binding(I don't see how you would set a listener for the Spinners). Below is a small example on how you might do this(although probably not a pretty way of doing it):
public class CustomAdapter extends SimpleCursorAdapter {
private LayoutInflater mInflater;
public CustomAdapter(Context context, int layout, Cursor c,
String[] from, int[] to) {
super(context, layout, c, from, to);
mInflater = LayoutInflater.from(context);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
ViewHolder holder = (ViewHolder) view.getTag(); // the holder
// pattern
// set the text for the TextView in your row
holder.name
.setText(cursor.getString(cursor.getColumnIndex("name")));
// status of the CheckBox from the database
int status = cursor.getInt(cursor.getColumnIndex("pl_selected"));
// set the CheckBox status
holder.ckb.setChecked((status > 0) ? true : false);
// get the id of this particular row, we'll use this later in the
// Spinner's listeners
long theId = cursor.getLong(cursor.getColumnIndex("_id"));
// see if it is time to show the Spinners
if (status > 0) {
// it is time to show the Spinners. Here you would do stuff
// like: setting up the Spinner's adapters + setting the
// listener
// I used a Spinner with entries set in the xml layout(so my
// selection result is a String)
holder.spin1.setVisibility(View.VISIBLE);
holder.spin2.setVisibility(View.VISIBLE);
// set theId as a tag so you know which Spinner was acted on
holder.spin1.setTag(new Long(theId));
holder.spin1
.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {
Long realRowId = (Long) parent.getTag();
// I don't know
ContentValues cv = new ContentValues();
// the column where I saved the spinner selected
// item is called "saved_item"
cv.put("saved_item", (String) parent
.getItemAtPosition(position));
// mDb is my SQLiteDatabase instance
mDb.update("tbl", cv, "_id = ?",
new String[] { String
.valueOf(realRowId) });
// I don't know how you saved the data, the
// above is just an example
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
// also implement the second Spinner like the first one
} else {
// required to prevent a recycled View from causing damage
holder.spin1.setVisibility(View.GONE);
holder.spin2.setVisibility(View.GONE);
}
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View v = mInflater.inflate(R.layout.adapters_listspinner_row,
parent, false);
ViewHolder holder = new ViewHolder();
holder.spin1 = (Spinner) v.findViewById(R.id.spinner1);
holder.spin1.setFocusable(false);
holder.spin2 = (Spinner) v.findViewById(R.id.spinner2);
holder.spin2.setFocusable(false);
holder.name = (TextView) v.findViewById(R.id.textView1);
holder.ckb = (CheckBox) v.findViewById(R.id.checkBox1);
holder.ckb.setFocusable(false);
v.setTag(holder);
return v;
}
class ViewHolder {
Spinner spin1, spin2;
TextView name;
CheckBox ckb;
}
}
Also, the required onListItemcClick method:
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// manage the CheckBox state
CheckBox ckb = (CheckBox) v.findViewById(R.id.checkBox1);
ckb.setChecked(!ckb.isChecked());
ContentValues cv = new ContentValues();
cv.put("pl_selected", ckb.isChecked() ? 1 : 0);
mDb.update("tbl", cv, "_id = ?",
new String[] { String.valueOf(id) });
// requery the database so the changes are seen by the adapter, this is horrible!
Cursor re = mDb.query("tbl", null, null, null, null, null, null);
mAllSs.changeCursor(re);
}
As an advice, maybe you could modify the layout of your app and move the Spinners out of the ListView row.

How to get the row position in a listview when a button is clicked inside it

This is my code where im fetching the values from database a displaying them in their respective fields i have designed a customlist where i have 5 textviews and 3 buttons
My problem is how to make those buttons clickable and i want that row information in the next activity.
cursor = db.rawQuery("SELECT * FROM JOB_LIST_DISPLAY_TABLE",null);
adapter = new SimpleCursorAdapter(this,R.layout.customlist,cursor,
new String[] {"JOB_TITLE","JOB_START_DATE","JOB_END_DATE","JOB_STATE","JOB_SPECIALITY","JOBPERMANENT",},
new int[] {R.id.Title,R.id.StartDate,R.id.EndDate,R.id.State,R.id.Speciality,R.id.JobType});
listview.setAdapter(adapter);
Each Row in a listview consists these elements
Screen looks like below
TextView1
Textview2
Textview3
Textview4
Textview5
Button1 Button2 button3

list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
});
where position is row number

If I have not misunderstood you have to implement
onListItemClick that have as parameter
position The position of the view in the list
then you can you
youradapter.getItem(position)
see the doc at:
getItem(int)

listview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.d("list item position","="+position);
/* If you want this position in next activity then put it in bundle extra and start the activity,ten fetch it from bundle in the next activity*/
}
});

In order to catch events from the List items, you're going to have to create a custom Adapter. Within the adapter you'll populate the data in the controls yourself. You can also register for events with those controls. To tell which row the control is from, you'll need to set the tag on the controls with either the row # or cursor value. You can then get that back from the control when an event is triggered.
Here is an example of a custom adapter. It might point you in the right direction:
public class MyAdapter extends ResourceCursorAdapter {
private static final class ViewHolder {
public TextView mControl1;
public TextView mControl2;
}
private int mData1Col;
private int mData2Col;
public MyAdapter(Context context, Cursor cursor) {
super(context, R.layout.history_entry, cursor, true);
// Store cursor column indexes for efficiency.
if ( null != cursor ) {
mData1Col = cursor.getColumnIndex(DATA1);
mData2Col = cursor.getColumnIndex(DATA2);
}
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
// This method creates new views as needed. Most controls only create
// views they need to fill the visible display area, then they re-use them.
// Let the parent create the view we specified at construction.
View view = super.newView(context, cursor, parent);
// For efficiency, use a view holder to reference the child views.
// These find operations can be expensive so do it just once.
ViewHolder vh = new ViewHolder();
vh.mTitle = (TextView) view.findViewById(R.id.control1);
vh.mAt = (TextView) view.findViewById(R.id.control2);
view.setTag(vh);
return (view);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
// This methods binds the specified cursor data with the provided view.
// Use the ViewHolder to find the controls we need and populate them.
ViewHolder vh = (ViewHolder) view.getTag();
// Populate the controls with the current cursor.
// Register to receive events from the controls.
// Set the tag on your controls with the cursor position so you
// have that info when the item is selected.
}
#Override
public Cursor swapCursor(Cursor newCursor) {
// Store column indexes for efficiency.
if (null != newCursor) {
mData1Col = newCursor.getColumnIndex(DATA1);
mData2Col = newCursor.getColumnIndex(DATA2);
} else {
mTitleCol = 0;
mResolvedAtCol = 0;
}
return (super.swapCursor(newCursor));
}
}
