This code is working fine on my phone galaxy note 2(custom rom of note 4.. Android 4.4.4).By fine I mean I can type in edittext and popupwidow shows up after 3rd text(because of condition I have put) and I can select an option from the popupwindow. When I try to run the code on any other phone like galaxy grand then callback to ItemsDropdownOnItemClickListener is not registered and I can only scroll the popupwindow and keep on typing in edittext but cannot select any of the options in the popupwindow. If I set popupWindowItems.setFocusable(false) to true i.e popupWindowItems.setFocusable(true), and then as soon as I type 3rd letter in edittext,edittext looses focus and popwindow gains it. Now I can select anything.. But now I cannot continue to type in edittext.I have to manually select edittext and type.
Now I want that after tying 3rd word in edittext a popupwindow should appear(which currently is appearing) and edittext doesn't loose focus(so that i can continue typing).. Further if I select anything from popupwindow ,ItemsDropdownOnItemClickListener should be called which is currently being not called in other phones when popupWindowItems.setFocusable(false);
I am doing this to load data from sqlite database and show in popupwindow once the user types 3rd word. Any suggestion is recommended
Edit: Problem solved. Now using AutoComplete TextView

//HistoryAdapt

you are getting this error because you have never intialized the object of your adapter class
HistoryAdapt in requires a context and and list to pass into it ,as defined in your constructor

This may be because Listitems is still referencing to null object. Have you called HistoryAdapt(context,items) constructor before calling
HistoryItems l_myLastItem= (HistoryItems) myLastItem.getLastElement(0);
?

Do as Haresh Chhelana said
public HistoryItems getLastElement(){
return items.get(items.size()-1);
}
the reason you are getting null pointer exception is because your list has not been initialized so it is referencing null. To get rid of this error you should first initialize your ArrayList then populate it as
//### SET LAST ELEMENT INTO TEXTVIEW
m_myListItem = new ArrayList();
//then add some data to arrayList for eg:
for (i=1;i<=10;i++){
m_myListItem.add(new HistoryItem().setTitle("title " + i));
}
myLastItem=new HistoryAdapt(mContext, m_myListItem ); //this should be m_myListItem not m_myLastItem
m_myLastItem= myLastItem.getLastElement();// m_myLastItem should be of type HistoryItem as HistoryItem m_myLastItem not List<HistoryItems> m_myLastItem
mSignal.setText(m_myLastItem.getTitle());
P.S. please have a look at your variable naming convention

No need to pass last item index instead directly get index from adapter list size.
public HistoryItems getLastElement(){
return items.get(items.size()-1);
}

thank you..

You cannot put OnClickListeners on the contents of an info window. The info window itself is not displaying your layout, but rather a Bitmap generated from the layout. This is covered in the documentation:
As mentioned in the previous section on info windows, an info window is not a live View, rather the view is rendered as an image onto the map. As a result, any listeners you set on the view are disregarded and you cannot distinguish between click events on various parts of the view. You are advised not to place interactive components — such as buttons, checkboxes, or text inputs — within your custom info window.
You can use setOnInfoWindowClickListener() to find out when the info window itself is tapped.

As explained in other answers what you want to achieve is not supported directly by Google Maps Android API v2, but...
you can do what you need by putting yourself in front of MapFragment or MapView, handle MotionEvents to make your OnClickListeners be called.
See this answer for a nice (but hackish) how-to: https://stackoverflow.com/a/15040761/2183804

yes you cannot add listener on the view of info window. One thing you can do , onInfoWindowClick show alert menu and give the user some options.
mMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker arg0) {
final CharSequence[] items = { "message", "call"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Call");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if (item == 0) {
sendMessage();
} else {
makeCall();
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
Or you can try something like this..
I am not sure whether its work or not.

getParcelableArrayListExtra issue. Program crashing

I'm trying to pass an arraylist of objects to a new activity, I followed a tutorial and it looks as if I've done everything right but my program kept crashing. I've commented out the majority of the code to isolate the line that seems to be causing the crash and its the getParcelableArrayListExtra bit that seems to be the problem. Can anyone help?
New Activity:
public class DatabaseSearch extends ListActivity{
DBAdapter db = new DBAdapter(this);
ArrayList<String> listrecipes = new ArrayList<String>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.databasesearch);
Intent i = getIntent();
if (i != null) {
ArrayList<mydata> data = i.getParcelableArrayListExtra ("com.example.MyPantry.array");
}
}
}
Bit of code from the old activity--
I don't know if it matters but the new activity is being called within a dialog box
#Override
protected Dialog onCreateDialog(int id)
{
switch(id) {
case 0:
return new AlertDialog.Builder(this)
.setIcon(R.drawable.icon)
.setTitle("List all recipes that match over:")
.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
// TODO Auto-generated method stub
switch (item)
{
case 0:
percentageselected = 25;
break;
case 1:
percentageselected = 50;
break;
case 2:
percentageselected = 75;
break;
case 3:
percentageselected = 100;
break;
default:
break;
}
}
})
.setPositiveButton("OK", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton)
{
if (percentageselected == 0)
{
Toast.makeText(getBaseContext(), "Please make a selection", Toast.LENGTH_SHORT).show();
}
else
{
Intent intent = new Intent(getBaseContext(), DatabaseSearch.class);
intent.putParcelableArrayListExtra("com.example.MyPantry.array", array);
startActivity(intent);
}
}
})
.setNegativeButton("Cancel", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton)
{
dialog.dismiss();
}
})
.create();
}
return null;
}
My objects inside the array I want to pass--
public class mydata implements Parcelable {
private int recipeID;
private int ingredientID;
private String check = "unchecked";
private int percentage = 0;
#Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
#Override
public void writeToParcel(Parcel data, int flags) {
// TODO Auto-generated method stub
data.writeInt(recipeID);
data.writeInt(ingredientID);
data.writeString(check);
data.writeInt(percentage);
}
//Other functions
}
Lastly I have this class that the tutorial instructed me to make...
public class MyCreator implements Parcelable.Creator<mydata> {
#Override
public mydata createFromParcel(Parcel source) {
// TODO Auto-generated method stub
return new mydata(source);
}
#Override
public mydata[] newArray(int arg0) {
// TODO Auto-generated method stub
return new mydata[arg0];
}
}
So I know it's quite a bit to look at but I'm just trying to be thorough. The problem starts to occur inside the if statement in the new activity.

When just passing data between intents, you can just mark your classes as Serializable (by implementing the Serializable marker interface) and add them directly to the intent as extras without having to do all this work with parcelable (parcelable is really only needed when binding to services).
It's hard to say why you're getting the error without seeing a stack trace or the constructor for mydata that populates the class using the Parcel.

It is possible to start a Intent from ItemizedOverlay class? (mapview item)

I have a mapview, with itemizedoverlays, exactly like in the example of android developers guide: http://developer.android.com/resources/tutorials/views/hello-mapview.html
on the itemizedoverlay, i have a personalized dialog, with a button. all fine until here, but now i have problems trying to add the functionality to the button. I need that the button start's a new activity, but i can't achieve that.... ¿why? because on this line: i = new Intent (NyItemizedOverlay.class, Locate.class); i have the current Intent class as first parameter, and the target intent class at second parameter.
MyItemizedOverlay is not a Intent class... it's ItemizedOverlay extension, then it doesn't compile when i try to launch the intent, i am trying to pass a normal class as first argument, and it needs an intent class. I have to put the launcher class, but the launcher class is not an intent :S
If i try to put another intent class on the first argument, i got this error: No enclosing instance of the type AllActivity is accessible in scope .... (AllActivity is a public activity class of my app)
How i can solve this?
full code here:
public class MyItemizedOverlay extends ItemizedOverlay {
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
private ArrayList<String> permissions = new ArrayList<String>();
private Context mContext;
public MyItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
}
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
public int size() {
return mOverlays.size();
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
public void addOverlay(OverlayItem overlay,String permission) {
mOverlays.add(overlay);
permissions.add(permission);
populate();
}

The Intent javadoc clearly show that the first arg has to be a Context (extended by activity) and the second one the class of the activity you're trying to launch. In your case, you'll need to do :
Intent intent = new Intent(mContext, AllActivity.class);
mContext.startActivity(intent);

generally, Intent gets in one of its constructor Context as first parameter and an Activity class as the second one. So, do the following:
Intent intent = new Intent(mContext, AllActivity.class);
mContext.startActivity(intent);

To an intent constructor it should pass A Context of the application package implementing this class, check this. it is not the intent.
It must be some Activity, say MyClass that using your MyItemizedOverlay class. Best thing to do is declare a static Context say myContext there and declare its value as myContext = MyClass.this; in onCreate. Then you can declare intent like this
new Intent (MyClass.myContext , Locate.class);
