我需要创建一个带有两个按钮的警报对话框作为视图。我创建了它，但问题是在单击其中一个视图时执行的操作后我无法关闭它。这意味着在第一个按钮中
这就是我要找的
我的覆盖类
public class AddItemizedOverlay extends ItemizedOverlay<OverlayItem> {
private ArrayList<OverlayItem> mapOverlays = new ArrayList<OverlayItem>();
DatabaseHandler db;
private Context context;
double lat;
double lon;
// Alert Dialog Manager
AlertDialogManager alert = new AlertDialogManager();
public AddItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
}
public AddItemizedOverlay(Drawable defaultMarker, Context context) {
this(defaultMarker);
this.context = context;
}
@Override
public boolean onTouchEvent(MotionEvent event, MapView mapView)
{
if (event.getAction() == 1) {
GeoPoint geopoint = mapView.getProjection().fromPixels(
(int) event.getX(),
(int) event.getY());
db = new DatabaseHandler(context);
// latitude & longtitude (double)
lat = geopoint.getLatitudeE6() / 1E6;
lon = geopoint.getLongitudeE6() / 1E6;
}
return false;
}
@Override
protected OverlayItem createItem(int i) {
return mapOverlays.get(i);
}
@Override
public int size() {
return mapOverlays.size();
}
@Override
protected boolean onTap(int index) {
OverlayItem item = mapOverlays.get(index);
final String title= item.getTitle();
final String snippet= item.getSnippet();
if(title.equalsIgnoreCase("Your Location")){
alert.showpickAlertDialog1(context, title, snippet);
}
else if(title.equalsIgnoreCase("0")||title.equalsIgnoreCase("2")||title.equalsIgnoreCase("3")){
String lati = String.valueOf(lat);
String longi = String.valueOf(lon);
alert.showpickAlertDialog2(context, lati, longi, snippet);
}
else if(title.equalsIgnoreCase("1")||title.equalsIgnoreCase("4")||title.equalsIgnoreCase("5")||title.equalsIgnoreCase("6")){
}
return true;
}
public void addOverlay(OverlayItem overlay) {
mapOverlays.add(overlay);
}
public void populateNow(){
this.populate();
}
}
自定义的 AlertDialogManager 类
public class AlertDialogManager {
private Context context;
DatabaseHandler db = new DatabaseHandler(context);
public void showAlertDialog(Context context, String title, String message,
Boolean status) {
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
// Setting Dialog Title
alertDialog.setTitle(title);
// Setting Dialog Message
alertDialog.setMessage(message);
if(status != null)
// Setting alert dialog icon
alertDialog.setIcon((status) ? R.drawable.success : R.drawable.fail);
// Setting OK Button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
System.exit(0);
}
});
// Showing Alert Message
alertDialog.show();
}
public void showpickAlertDialog2(final Context context, final String lat, final String lon,final String snippet) {
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
LinearLayout layout = new LinearLayout(context);
layout.setOrientation(LinearLayout.VERTICAL);
final Button park_button = new Button(context);
park_button.setHint("Park here");
// park_button.setBackgroundResource();
layout.addView(park_button);
park_button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
System.out.println("parkbutton:Clicked");
// Delete DB Values
int count = db.getDatasCount();
for(int i = 0;i<count;i++){
db.deleteValues(i);
}
//latitude & longtitude (string)
String latitude = lat;
String longtitude = lon;
Log.d("Insert: ", "Inserting ..");
db.addData(new Datas(latitude, longtitude));
// Toast.makeText(context, "Lat: " + lat + ", Lon: "+lon, Toast.LENGTH_SHORT).show();
// Reading DB Data
Log.d("Reading: ", "Reading all Values...");
List<Datas> datas = db.getAllDatas();
for (Datas dat : datas) {
String log = "Id: "+dat.getID()+" ,Latitude: " + dat.getlat() + " ,Longtitude: " + dat.getlon();
// Writing DB data to log
Log.d("DB Data: ", log);
}
park_button.setEnabled(false);
}
});
Button know_more_button = new Button(context);
know_more_button.setHint("Know more");
// park_button.setBackgroundResource();
layout.addView(know_more_button);
know_more_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
SharedPreferences prefs = context.getSharedPreferences("myprefs", 0);
SharedPreferences.Editor editor =prefs.edit();
editor.putString("KEY_REFERENCE", snippet);
editor.commit();
Intent intent = new Intent(context, SinglePlaceActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
});
alertDialog.setView(layout);
alertDialog.setButton("Back", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
// Showing Alert Message
alertDialog.show();
}
public void showpickAlertDialog1(Context context, String title, String message) {
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
alertDialog.setTitle(title);
alertDialog.setMessage(message);
alertDialog.setButton("Back", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
// Showing Alert Message
alertDialog.show();
}
}
