How do I replace my popupmenu code with ListPopupWindow?

How do I replace my popupmenu code with ListPopupWindow? - android

Currently , I am programatically creating a popupmenu which displays a list of floors and a title. However, changing the background color of just the title and adding a close button to title is turning out to be a nightmare.
I want to replace this popupmenu with a list popup window so I can add an XML file with background attribute for the title with a black color as the background and a close button on the right and white background for items in the menu. Is there a way I can achieve this with list popup window? Here's my code for that:
private void floorMenu(ImageView btnFloorMenu){
MapData data = new MapDao(MyPlugin.mapId);
final List<Floor> flList = dao.getFloors();
// set popupMenu
final PopupMenu floorsPm = new PopupMenu(MapViewActivity.this,btnFloorMenu);
MenuItem titleItem = floorsPm.getMenu().add(Menu.NONE, Menu.NONE, Menu.NONE, "Floors");
int i = 1;
for(Floor fl : flList)
{
floorsPm.getMenu().add(Menu.NONE, i,i, fl.getName());
if(i>3)
break;
i++;
}
// add popup listener
floorsPm.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
// onClick
#Override
public boolean onMenuItemClick(MenuItem item){
// get floorname
int flOrder = item.getOrder();
if(flOrder == Menu.NONE )
return true;
flOrder--;
final String floorId = flList.get(flOrder).getMapId();
// set camera to floor
runOnUiThread(new Runnable() {
#Override
public void run() {
floorsPm.dismiss();
mapFragment.getMapManager().setCameraLayer(floorId, false);
Log.d(TAG, "post cameraLayer set");
changedSteps = true;
pauseNav();
}
});
return true;
}
});
floorsPm.show();
}

Here is my example to create show a ListPopupWindow
First, create layout item_list_popup_window for each item of ListPopupWindow
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#e4e4e4"
android:paddingTop="1dp"
android:orientation="horizontal">
<TextView
android:id="#+id/text_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1" />
<Button
android:id="#+id/button_delete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Delete" />
</LinearLayout>
Second, create an Adapter for your ListPopupWindow like
public class ListPopupWindowAdapter extends BaseAdapter{
private Activity mActivity;
private List<String> mDataSource = new ArrayList<>();
private LayoutInflater layoutInflater;
private OnClickDeleteButtonListener clickDeleteButtonListener;
ListPopupWindowAdapter(Activity activity, List<String> dataSource, #NonNull OnClickDeleteButtonListener clickDeleteButtonListener){
this.mActivity = activity;
this.mDataSource = dataSource;
layoutInflater = mActivity.getLayoutInflater();
this.clickDeleteButtonListener = clickDeleteButtonListener;
}
#Override
public int getCount() {
return mDataSource.size();
}
#Override
public String getItem(int position) {
return mDataSource.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if(convertView == null){
holder = new ViewHolder();
convertView = layoutInflater.inflate(R.layout.item_list_popup_window, null);
holder.tvTitle = (TextView) convertView.findViewById(R.id.text_title);
holder.btnDelete = (Button) convertView.findViewById(R.id.button_delete);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
// bind data
holder.tvTitle.setText(getItem(position));
holder.btnDelete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
clickDeleteButtonListener.onClickDeleteButton(position);
}
});
return convertView;
}
public class ViewHolder{
private TextView tvTitle;
private Button btnDelete;
}
// interface to return callback to activity
public interface OnClickDeleteButtonListener{
void onClickDeleteButton(int position);
}
}
Third, You create a function for create and show ListPopupWindow
private void showListPopupWindow(View anchorView) {
final ListPopupWindow listPopupWindow = new ListPopupWindow(this);
listPopupWindow.setWidth(600);
List<String> sampleData = new ArrayList<>();
sampleData.add("A");
sampleData.add("B");
sampleData.add("CCCCCCCCCCCCCC");
sampleData.add("D");
sampleData.add("EEEEEEEEE");
listPopupWindow.setAnchorView(anchorView);
ListPopupWindowAdapter listPopupWindowAdapter = new ListPopupWindowAdapter(this, sampleData, new ListPopupWindowAdapter.OnClickDeleteButtonListener() {
#Override
public void onClickDeleteButton(int position) {
Toast.makeText(MainActivity.this, "Click delete " + position, Toast.LENGTH_SHORT).show();
listPopupWindow.dismiss();
}
});
listPopupWindow.setAdapter(listPopupWindowAdapter);
listPopupWindow.show();
}
Finally, you can show the ListPopupWindow by
showListPopupWindow(v);
for example, if you want to show it when click button
anyButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showListPopupWindow(v);
}
});
Full Demo is here

Please Try this code, Maybe you wont like this
private void floorMenu(ImageView btnFloorMenu){
final Dialog customDialog = new Dialog(this);
customDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
customDialog.setContentView(R.layout.item_dialog_coustom_design);
TextView clickItem = (TextView)customDialog.findViewById(R.id.item_click);
TextView clickItem1 = (TextView)customDialog.findViewById(R.id.item_click1);
TextView clickItem2 = (TextView)customDialog.findViewById(R.id.item_click2);
Button btnClose = (Button)customDialog.findViewById(R.id.btn_close);
clickItem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
// wright your Button Action
}
});
clickItem1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
// wright your Button Action
}
});
clickItem2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
// wright your Button Action
}
});
btnClose.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
customDialog.dismiss();
}
});
customDialog.show();
}
Create Linearlayout layout_width="280dp" layout_height="wrap_content"
android:orientation="vertical" file name item_dialog_coustom_design.xml then put this code
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Title"
android:background="#000"
android:textColor="#fff"
android:padding="12dp"
android:textSize="20sp"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp"
android:background="#fff"
android:padding="10dp"
android:text="Your Item"
android:id="#+id/item_click"
android:textSize="16sp" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp"
android:background="#fff"
android:padding="10dp"
android:text="Your Item"
android:id="#+id/item_click1"
android:textSize="16sp" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp"
android:background="#fff"
android:padding="10dp"
android:text="Your Item"
android:id="#+id/item_click2"
android:textSize="16sp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:paddingRight="10dp"
android:paddingBottom="10dp"
android:background="#fff"
android:gravity="right">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btn_close"
android:text="Close"/>
</LinearLayout>

Wrong behavior when click on item in recyclerView to change its color?

I'm trying to change the background color of the clicked item in RecyclerView from the adapter and it works, but the problem is when I click on position 1 it changes the color of position 1 and 7, and when I click on position 2 it changes the color of position 2 and 8 and so on ...
public class RecyclerViewAdapter extends
RecyclerView.Adapter<RecyclerViewAdapter.viewHolder> {
private ArrayList<String> name = new ArrayList<>();
private Context context;
boolean added = false;
public RecyclerViewAdapter(ArrayList<String> name, Context context) {
this.name = name;
this.context = context;
}
#Override
public viewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_horizontal_listview, parent, false);
return new viewHolder(view);
}
#Override
public void onBindViewHolder(final viewHolder holder, final int position) {
holder.cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
final Dialog dialog = new Dialog(view.getContext());
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.add_item_dialog_small);
Window window = dialog.getWindow();
window.setLayout(500, 450);
Button addToList = (Button) dialog.findViewById(R.id.addToList);
addToList.setOnClickListener(new View.OnClickListener() {
#SuppressLint("ResourceAsColor")
#Override
public void onClick(View v) {
holder.cardView.setBackgroundColor(R.color.layer4);
dialog.dismiss();
}
});
dialog.show();
}
});
}
Edit:
here is the cardView :
<android.support.v7.widget.CardView

In case of implementing options (such as favorite icon, checkbox, highlight or ...) to each row of a recyclerview, i think the best way is to create an object with your arbitrary parameter. for example for favorite a boolean parameter is best choice.
In your case you should create an object with a string and a boolean parameter with their setters and getters like below:
public class mObject {
private String name;
private boolean clicked;
// setters and getters
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isClicked() {
return clicked;
}
public void setClicked(boolean clicked) {
this.clicked = clicked;
}
}
and then set your data in a list of this object then pass it to the adapter.
In onBindViewHolder, first check click value, if is true change the color. then in onClick method do both change the boolean value and background color and finally use notifyDataSetChanged(); for updating view.
Your adapter onBindViewHolder should looks like below:
#Override
public void onBindViewHolder(RecyclerView.ViewHolder view,final int position) {
final MVH holder = (MVH) view;
holder.tv.setText(name.get(position).getName());
if (name.get(position).isClicked()){
holder.tv.setBackgroundColor(context.getResources().getColor(R.color.colorPrimary));
} else {
holder.tv.setBackgroundColor(context.getResources().getColor(R.color.colorAccent));
}
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
final Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.add_item_dialog_small);
Window window = dialog.getWindow();
window.setLayout(500, 450);
Button addToList = (Button) dialog.findViewById(R.id.addToList);
addToList.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (name.get(position).isClicked()){
name.get(position).setClicked(false);
holder.tv.setBackgroundColor(context.getResources().getColor(R.color.colorPrimary));
} else {
name.get(position).setClicked(true);
holder.tv.setBackgroundColor(context.getResources().getColor(R.color.colorAccent));
}
dialog.dismiss();
notifyDataSetChanged();
}
});
dialog.show();
}
});
}

You can simplyfy your code using lambdas, that's for sure.
This:
addToList.setOnClickListener(new View.OnClickListener() {
#SuppressLint("ResourceAsColor")
#Override
public void onClick(View v) {
holder.cardView.setBackgroundColor(R.color.layer4);
}
dialog.dismiss();
}
});
You can change to:
addToList.setOnClickListener((View v) -> {
holder.cardView.setBackgroundColor(R.color.layer4);
}
dialog.dismiss();
}
});

store var positionClicked in your adapter so it will be
onClick{positionClicked = position)
and then in your onBindViewHolder put
if(positionClicked==position){
//change color of element here//
}

I face this problem also. What you can do is set the background colour before click in onBindViewHolder method.
#Override
public void onBindViewHolder(final viewHolder holder, final int position) {
holder.cardView.setBackgroundColor(R.color.defaultBackgroundColour);

Android - SetOnItemClickListener doesn't work

I know here we have a lot of questions like mine, but I don't know why none works for me.
My objective: I have an AlertDialog with a ListView with a check box in each row, I can select some of the items, and I wish to make an ArrayList with the elements selected.
For that reason, I'm calling the SetOnclickListener, I put a Log inside the method, but does nothing.
I tried with focusable and clickable almost everywhere, but my Log doesn't appear.
Here My alert Dialog
private void callAdditionalDialog() {
LayoutInflater layoutInflater = LayoutInflater.from(ConfigProductActivity.this);
final View additionalView = layoutInflater.inflate(R.layout.dialog_additional, null);
additionalView.setFocusable(true);
// set the custom dialog components - text, buttons, accountants
TextView titleDialog = (TextView) additionalView.findViewById(R.id.title_additional);
titleDialog.setTypeface(boldFont);
Button buttonAccept = (Button) additionalView.findViewById(R.id.button_accept);
buttonAccept.setTypeface(boldFont);
Button buttonCancel = (Button) additionalView.findViewById(R.id.button_cancel);
buttonCancel.setTypeface(boldFont);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(ConfigProductActivity.this);
alertDialogBuilder.setView(additionalView);
final AlertDialog alertD = alertDialogBuilder.create();
alertD.setCanceledOnTouchOutside(false);
//Fill object of additional
final ListView additionalListView = (ListView) additionalView.findViewById(R.id.list_additional);
TextView additionalNotFound = (TextView) additionalView.findViewById(R.id.additional_not_found);
if (!withoutModifiers){
additionalAdapter = new AdditionalAdapter(ConfigProductActivity.this, additionalList);
additionalListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
additionalListView.setAdapter(additionalAdapter);
final ArrayList<ModifierEntity> modifierList = new ArrayList<ModifierEntity>();
additionalListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,
View view, int position, long id) {
Object modifier = additionalListView.getAdapter().getItem(position).toString();
Log.d(TAG, "SOMETHIIIIING");
}
});
}
else{
additionalListView.setVisibility(View.GONE);
additionalNotFound.setVisibility(View.VISIBLE);
additionalNotFound.setTypeface(font);
buttonCancel.setVisibility(View.GONE);
}
//End of fill object of additional
buttonCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
buttonAccept.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//additional.setText(additionalAdapter.getCount());
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
alertD.show();
}
Here my adapter:
public class AdditionalAdapter extends ArrayAdapter {
private static String TAG = AdditionalAdapter.class.getName();
private List<ModifierEntity> originalData = null;
private ConfigProductActivity activity;
private Typeface font;
private Typeface boldFont;
private static ModifierEntity modifier;
public AdditionalAdapter (ConfigProductActivity activity, List<ModifierEntity> listArray){
super(activity, R.layout.additional_item);
this.activity = activity;
this.originalData = listArray ;
font = Typeface.createFromAsset(activity.getAssets(),"HelveticaNeueThn.ttf");
boldFont = Typeface.createFromAsset(activity.getAssets(), "avgardm.ttf");
}
public static class Row
{
public TextView labelName;
public TextView labelPrice;
public CheckBox check;
}
#Override
public int getCount() {
return originalData.size();
}
#Override
public ModifierEntity getItem(int position) {
return originalData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final int colorFont = activity.getResources().getColor(R.color.brown_tataki);
final Row holder;
View rowView = convertView;
// reuse views
if (convertView == null) {
holder = new Row();
LayoutInflater inflater = LayoutInflater.from(activity);
rowView = inflater.inflate(R.layout.additional_item, null);
rowView.setClickable(true);
//rowView.setFocusable(false);
// configure view holder
holder.labelName = (TextView) rowView.findViewById(R.id.additional_name);
holder.labelPrice = (TextView) rowView.findViewById(R.id.additional_price);
holder.check = (CheckBox) rowView.findViewById(R.id.additional_check);
rowView.setTag(holder);
}
else {
holder = (Row) convertView.getTag();
// rowView.setClickable(true);
}
final ModifierEntity itm = originalData.get(position);
holder.labelName.setText(itm.getModifier_name());
holder.labelName.setTypeface(font);
holder.labelName.setTextColor(colorFont);
holder.labelPrice.setText(GlobalParameters.CURRENCY.concat(String.valueOf(itm.getModifier_cost())));
holder.labelPrice.setTypeface(boldFont);
holder.labelPrice.setTextColor(colorFont);
return rowView;
}
}

Using interfaces I can solve my problem, this link provided me the solution, and bassically consist in create an interface and implement in my activity.
Like this:
1.- Interface
public interface MyListener {
void folderClicked();
}
2.- Implements the interface in the activity
public class ActivityA extends Activity implements MyListener
3.- You will have to auto override the method folderClicked it will look like this:
#Override
protected void folderClicked() {
// Do your stuff here.
}
4.- Send the activity listener to the adapter with constructor like this:
MyAdpater adapter = new MyAdpater(ActivityA.this);
5.- Your adapter class your code should be like this:
public class TimeLineAdapter extends BaseAdapter {
private MyListener mListener;
public TimeLineAdapter(MyListener listener) {
super();
mListener = listener;
}
holder.iconImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mListener.onFolderClicked()
//code to do stuff when the image is clicked
}

Button click event with Custom List view

I have two button at bottom i.e after listview ends.
I am using a custom listview which display list items with alternate colors.
how to set setOnClickListener for both button at bottom?
public class PieMainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mRes = getResources();
new Random(new Date().getTime());
solbtn = (Button)findViewById(R.id.solution);
String recive ;
Bundle b = getIntent().getExtras();
final int piewrong=b.getInt("piewrong");
final int pieright=b.getInt("pieright");
final int pieunclick=b.getInt("pieunclick");
setContentView(R.layout.piechart_result);
recive = pieright+"/20";
mPie.setUnit(recive);
data1 = new ArrayList<String>();
fillData() ;
listtotal =getIntent().getStringArrayListExtra("listtotal");
timeuse =getIntent().getStringArrayListExtra("timeused");
adapter1 = new ListAdapter(this, data1, listtotal,timeuse);
ListView lvMain = (ListView) findViewById(R.id.list);
lvMain.setAdapter(adapter1);
lvMain.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
int questionno = position+1;
Bundle b = new Bundle();
b.putInt("questionno",questionno);
b.putInt("piewrong",piewrong);
b.putInt("pieright",pieright);
b.putInt("pieunclick",pieunclick);
Intent in=new Intent(PieMainActivity.this,Solution.class);
in.putStringArrayListExtra("listtotal", (ArrayList<String>) listtotal);
in.putStringArrayListExtra("timeused", (ArrayList<String>) timeuse);
in.putExtras(b);
startActivity(in);
finish();
}
});
}
void fillData() {
for (int i = 1; i <= 20; i++) {
data1.add("Question " + i);
}
}
void fillcmp() {
for (int i = 1; i <= 20; i++) {
cmp.add("cmp " + i);
}
}
}

So these buttons are not part of your ListView? Well, than in your onCreate do something like:
solbtn = (Button)findViewById(R.id.solution);
solbth.setOnClickListener( toolbar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
yourMethod();
}
});
And the same goes for the second button.
Or you can make your Activity implement View.OnClickListener, after doing this you can set your click listeners like this:
//this two lines in your OnCreate
button1.setOnClickListener(this);
button2.setOnClickListener(this);
//somewhere later in the code
#Override
public void onClick(View v) {
//do something
}

Just add the clickListeners in your onCrete() method:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
solbtn = (Button) findViewById(R.id.home);
homebtn = (Button) findViewById(R.id.solution);
solbtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for solution button
}
});
homebtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for home button
}
});
.....
}

Spinner value disappear after layout visibility is changed + specific flows

I have a custom list view with layout contain two layouts, called upper and bottom.
upper layout contain spinner, set and remove buttons.
bottom layout contain text view and back button.
By default bottom layout is in GONE state and when the user clicks on set button upper layout is GONE and bottom is VISIBLE (clicking on back button in bottom layout will return upper bottom back).
my problem is spinner value is disappear after specific flows:
Flow 1:
Add two items
Click on SET button on the first item
Remove the second item
Click on 'Back' button on the first item
Flow 2:
Click on SET
Rotate screen
Click on Back
Just to be clear, spinner values are exist and if drop it down you'll found the names (and I have android:configChanges="keyboardHidden|orientation|screenSize" in my manifest).
So, why spinner value is disappear after those flows ?
Here is my code:
Names.java
public class Names
{
private String name;
private int nameIndex;
private Boolean isNameOnTop;
public Names()
{
name = "";
isNameOnTop = true;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNameIndex() {
return nameIndex;
}
public void setNameIndex(int nameIndex) {
this.nameIndex = nameIndex;
}

return isNameOnTop;

this.isNameOnTop = isNameOnTop;
}
}

In your ListviewAdapter, change:
// back
holder.btn_back.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
holder.relativeLayout_Upper.setVisibility(View.VISIBLE);
holder.relativeLayout_Bottom.setVisibility(View.GONE);
getItem(holder.index).setIsNameOnTop(true);
}
});
to:
// back
holder.btn_back.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
holder.relativeLayout_Upper.setVisibility(View.VISIBLE);
holder.relativeLayout_Bottom.setVisibility(View.GONE);
getItem(holder.index).setIsNameOnTop(true);
notifyDataSetChanged();
// OR you can use this
// holder.spNames.requestLayout();
}
});

Whenever you click on "Add" in the method onOptionsItemSelected() you add an object new names() into the list, and in the Names class, the value of attribute name is set to ""
I guess that's why you getting an empty item in the spinner.

ViewHolder messing Views

I have implemented both a ViewHolder and a convertView in my listView.
My listView is populated by a custom adapter, with a list of bookings.
When I click on an item, an invisible layout slides in from right to left, to display buttons.
I can dismiss this overlaying layout by clicking on a dismiss button so that it gets hidden again.
On this overlaying layout, I have a delete Button, which enables me to delete the item.
So far so good.
When I erase an item the item disappears as expected, the adapter is then reloaded.
The item below takes the position of the deleted item, but remains invisible.
I know it is here, because I can still click on the item to trigger the overlaying View.
So the ovelaying view is visible but not the item. I have no idea why this is happening.
I suspect the ViewHolder to be responsible of this behaviour, but I can't find a solution.
Thank you for your help.

Your problem comes from re-using the convertView.
When the previous item got a click the OnClickListener fired and in there the visibility for the item was set to GONE. Later on this same view got recycled and passed to getView() as the convertView. Because you are re-using it without resetting any changes that were made you are now working with a View for a new item that is not in a known state. You should make sure you undo any changes before using a convertView.
The quick fix is to not re-use the convertView that is passed into getView(). So, in your code where you check if you can re-use the convertView:
if(convertView == null)
Sabotage that check just to see if things start working:
if(true)
If that does the trick you will probably want to fix it properly.
In the else clause of the above check, you are getting the item holder from the tag. Also undo any changes that your OnClickListeners could have made. You want to start with a View for a new item in a known state. You should initialize it explicitly. For example:
if(convertView == null) {
// ... snipped all the initialization ...
} else {
holder = (ViewHolder)convertView.getTag();
convertView.setVisibility(View.VISIBLE);
}
Update
I have never used a 'heterogenous' adapter so I can't really answer why "the convertView is reusing the overlay View instead of my item's root View." The Android developer documentation for Adapter.getView() says about the convertView argument:
The old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. Heterogeneous lists can specify their number of view types, so that this View is always of the right type (see getViewTypeCount() and getItemViewType(int)).
The emphasized bit says that you cannot depend on the system to pass you a convertView of the right type, while the last sentence says the opposite (as I read it).
Basically, I don't know why it's not working. I guess in the test where you check if you must inflate a new view yourself
if(convertView == null)
you should also check if it is the right kind of view:
if(convertView == null || getItemViewTypeFromView(convertView) != type)
Where getItemViewTypeFromView() is something like this:
private int getItemViewTypeFromView(View view) {
switch (view.getId()) {
case R.id.item_layout_root:
return TYPE_ITEM;
case R.id.placeholder_layout_root:
return TYPE_PLACEHOLDER;
default:
throw new UnsupportedOperationException();
}
}
In the item and placeholder layouts, give the root elements an id so you distinguish between them. So something like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/item_layout_root"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="5dp"
android:paddingLeft="5dp"
android:paddingRight="5dp" >
... snipped the elements that make up the body of the layout ...
</RelativeLayout>
I haven't tried the above, so I hope it works for you.
Good luck!
