I have this app, that I created a custom dialog for. I must of goofed something up cause while the .show call on the dialog does indeed bring it up, it looks like a whole new fragment and it is not floating but instead replacing the ui with its contents. I did see in their help for DialogFragment:
http://hi-android.info/docs/reference/android/app/DialogFragment.html#Lifecycle
that one can embed a dialog as a regular fragment or not. Though I am not doing anything to do this so I cannot figure out why its acting like an embedded fragment and not floating. After thinking on it, is it the way I defined my XML definition? The dialogfragment example above didn't really give a definition for the xml layout, so maybe that is where my issue is? (Even added the gravity to the xml file, still no dice)
My xml definition for this Dialog is here:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:textSize="20sp"
android:text = "Location:"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left"/>
<Spinner
android:id="@+id/location_spinner"
android:layout_width = "450sp"
android:layout_height="wrap_content"/>
<!-- fill out the data on the package total cost etc -->
</LinearLayout>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button android:id="@+id/location_dlg_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Okay"/>
<Button android:id="@+id/location_dlg_cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Cancel"/>
<Button android:id="@+id/location_dlg_new"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Create new..."/>
</LinearLayout>
</LinearLayout>
Like I said displays just fine, the code for the fragment:
package com.viciousbytes.studiotab.subactivities.dialogfragments;
import ... ...
public class LocationPicker extends DialogFragment {
ArrayList<Location> mLocations;
public static LocationPicker newInstance()
{
LocationPicker loc = new LocationPicker();
return loc;
}
private void setLocations(ArrayList<Location> loc)
{
mLocations=loc;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Pick a style based on the num.
int style = DialogFragment.STYLE_NORMAL, theme = android.R.style.Theme;
setStyle(style, theme);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.location_dialog, container, false);
Spinner spinner = (Spinner)v.findViewById(R.id.location_spinner);
ArrayAdapter<Location> adapter = new ArrayAdapter<Location>(v.getContext(), android.R.layout.simple_spinner_item, mLocations);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
if(mLocations==null)
spinner.setPrompt("No Locations");
else
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new LocationSelectedListener());
// Watch for button clicks.
Button newBtn = (Button)v.findViewById(R.id.location_dlg_new);
newBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
//create new start that activity...
}
});
// Cancel do nothing dismissthis
Button cancelBtn = (Button)v.findViewById(R.id.location_dlg_cancel);
cancelBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
//create new start that activity...
}
});
// okay button means set listener with the selected location.
Button okBtn = (Button)v.findViewById(R.id.location_dlg_ok);
okBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
//create new start that activity...
}
});
return v;
}
}
It is called from a fragment itself? though does that matter? because I am calling a TimePIckerDialog and a DatePickerDialog and those work fine, but my calling code from my other fragment is:
void showLocationDialog() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment prev = getFragmentManager().findFragmentByTag("locpicker");
if (prev != null) {
ft.remove(prev);
}
ft.addToBackStack(null);
// Create and show the dialog.
DialogFragment newFragment = LocationPicker.newInstance();
newFragment.show(ft, "locpicker");
}
