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();
}
public MyItemizedOverlay(Drawable defaultMarker, Context context) {
//super(defaultMarker);
super(boundCenterBottom(defaultMarker));
mContext = context;
}
public void clear()
{
mOverlays.clear();
permissions.clear();//lista de permisos de cada usuario, ya que hay dos campos, el email (snippet) y el permission, una lista.
}
protected boolean onTap(int index) {
try{
OverlayItem item = mOverlays.get(index);
if (permissions.size()==0)
{
AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
dialog.setTitle(item.getTitle());
dialog.setMessage(item.getSnippet());
dialog.show();
}
else
{
//set up dialog
Dialog dialog = new Dialog(mContext);
dialog.setContentView(R.layout.personal_dialog);
dialog.setTitle(item.getTitle());
dialog.setCancelable(true);
//there are a lot of settings, for dialog, check them all out!
//set up text
TextView DialogEmail = (TextView) dialog.findViewById(R.id.DialogEmail);
TextView DialogPermission = (TextView) dialog.findViewById(R.id.DialogPermission);
DialogEmail.setText(item.getSnippet());
DialogPermission.setText(permissions.get(index));
final String userName=item.getTitle();
final String email=item.getSnippet();
final int cont=index;
//set up button
Button button = (Button) dialog.findViewById(R.id.DialogButton);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//do something
Bundle bundle = new Bundle(); //bundle is like the letter
bundle.putString ("user",userName ); //arg1 is the keyword of the txt, arg2 is the txt
bundle.putString ("email", email);
bundle.putString ("permission", permissions.get(cont));
Intent i=null;
i = new Intent (MyItemizedOverlay.class, Locate.class);
i.putExtras(bundle);
startActivity(i);
}
});
//now that the dialog is set up, it's time to show it
dialog.show();
}
}catch(Exception e){}
return true;
}
}
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);
