Possible duplicate here, sorry in that case...
I can't get my head around how to add a custom style to my DialogFragment. At the moment I have a class
public final class SelectFragment extends DialogFragment {
which I call from different parts of my app. E.g from my "CreateInvoice" class like this:
private void showFragment(int selectedIndex) {
SelectFragment fragment = SelectFragment.newInstance(selectedIndex, getOnOptionSelectListener());
fragment.setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme_Holo_Light_Dialog);
fragment.show(getActivity().getSupportFragmentManager(), "");
}
What I want to do is to change the fragment.setStyle to a custom one, for example with my own color scheme as color on the border, background etc.. And I would really appreciate if someone could walk me through it since it's the first time I've worked with fragments. :-)
Thanks!
The way I would do it is to simply write your own layout for your dialog, then load it up when you show the fragment
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
View v = inflater.inflate(R.layout.custom_dialog_layout, null, false);
builder.setView(v)
// Add action buttons
.setPositiveButton(R.string.save_note, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
// do stuff
}
})
.setNegativeButton(R.string.note_cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do stuff
}
});

Ok so I am trying change my background of my dialog box from white to a dark blue. However when I long press on one of the grid elements the dialog box looks like this:
I am trying to make it look something like this (this is a photoshop):
Here is snipet of my XML code for the edit dialog
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
android:background="#color/customBG">
Java code for custom dialog
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.edit_game_dialog,null);
editTitle = view.findViewById(R.id.editTitle);
editTitle.setText(currentTitle);
imageView = view.findViewById(R.id.item_image_dialog);
imageView.setImageResource(currentImage);
changeImageBt = view.findViewById(R.id.change_image);
changeImageBt.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
}
});
builder.setView(view).setTitle("Edit game")
.setPositiveButton("Apply Changes", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialogInterface, int i)
{
String title = editTitle.getText().toString();
int image = R.drawable.blank; //PLACE HOLDER CODE
editGameDialogListener.applyChanges(pos,title,image);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialogInterface, int i)
{
}
});
return builder.create();
}
I think you should use Dialog instead of AlertDialog.
Alert Dialog has its own Title and Button.
With Dialog you will have the benefit of defining your Title and Buttons.
Create a Layout as your design needs and set it in Dialog.
class ABC(context: Context) : Dialog(context) {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.your_custom_layout)
}
}
When you create your dialog, you can pass theme as a second param
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.MyDialogTheme);
and set the custom theme to override anything you need. For background color something like this should work:
<style name="MyDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:background">#color/customBG</item>
</style>
In my app I have an ElementListFragment of items represented by a code object Element. I've data-bound these elements to the list and they display the correct information.
However, to continue filling in the information in each item I put a button on each element that shows a Dialog with additional fields.
But when the Dialog opens the fields are all blank (where one at least ought to be filled) and any fields I fill don't save the data (and don't effect changes on the list).
Appart from the values not being bound (displayed or written), the application works fine. I've essentially tried multiple variations of the sugestions in this question. Here is the code:
public class ElementDialogFragment extends DialogFragment {
private Element mElement;
private Dialog dialog;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View v = inflater.inflate(R.layout.dialog_element, null);
final DialogSkillelementBinding binding = DialogElementBinding.inflate(LayoutInflater.from(getContext()));
builder.setView(v)
// Add action buttons
.setPositiveButton(R.string.save, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
//this was just an attempt to make it work
binding.executePendingBindings();
dialog.dismiss();
}
});
TextView Title = v.findViewById(R.id.skill_e_dialog_title);
Title.setText(ResourceLocator.getSkillName(mElement.getSkill()));
dialog = builder.create();
dialog.setContentView(binding.getRoot());
binding.setElement(mElement);
binding.executePendingBindings();
return dialog;
}
}
When debuging I've confirmed that mElement is correctly attributed, however it's also bound to the list shown beneath the dialog. The title is also displayed correctly.
Is there a problem double-binding an object?
Are some of the steps on the function maybe out of order?
Is the DialogBuilder somehow incompatible with databinding?
You should set LyfecycleOwner for your binding class for data updating.
binding.setLifecycleOwner(requireActivity())
I have implemented form in my dialog, and when positive button is clicked I create new object to ma database. I've created global variable for EditText's but still not work. Where I want get text value from them I always get empty string.
here is code:
EditText name, desc;
#Override
#NonNull
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
view = inflater.inflate(R.layout.new_dialog, null);
name = (EditText) view.findViewById(R.id.workout_name);
desc = (EditText) view.findViewById(R.id.workout_description);
builder.setView(inflater.inflate(R.layout.new_dialog, null)).setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
MyDbHelper helper = new MyDbHelper (getActivity());
MyObj w = new MyObj ();
w.setName(name.getText().toString(););
w.setDescription(desc.getText().toString());
w.setLevel(1);
long id = helper.createWorkout(w);
Toast.makeText(getActivity(), id+"", Toast.LENGTH_LONG).show();
callback.onPositiveButtonClick();
}
}).setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
callback.onNegativeButtonClick();
}
});
return builder.create();
}
Any ideas please?
I stumbled upon the same issue. You can get the views inflated in the dialog using getDialog() provided by the onClick.
((EditText) getDialog().findViewById(R.id.your_editText_ID)).getText().toString()
In below code, you are inflating new_dialog layout and your name and desc EditTexts belong to this layout.
view = inflater.inflate(R.layout.new_dialog, null);
name = (EditText) view.findViewById(R.id.workout_name);
desc = (EditText) view.findViewById(R.id.workout_description);
But when you are setting the layout of the dialog you are setting new_workout_dialog. your name and desc do not belong to this layout.
builder.setView(inflater.inflate(R.layout.new_workout_dialog, null))
Furthermore, even if you used new_dialog while setting the builders view, name and desc would still be irrelevant. Because you are completely creating a new view inside setView method.
Use the view variable as following:
builder.setView(view, null))
Hi guys I have a custom alert dialog I created. In the builder I set cancelable to false yet it still disappears when I press the back button, any ideas?
This is the code for the dialog:
public final class HemisphereDialogFragment extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View customTitle = inflater.inflate(R.layout.hemisphere_dialog_custom_title, null);
builder.setCustomTitle(customTitle);
String[] entries = new String[2];
entries[0] = getResources().getString(R.string.northern_hemisphere);
entries[1] = getResources().getString(R.string.southern_hemisphere);
builder.setItems(entries, new DialogInterface.OnClickListener() {
//The 'which' argument contains the index position of the selected item
public void onClick(DialogInterface dialog, int which) {
if( which == 0 ) {
GlobalVariables.getShared().setIsInNorthernHemisphere(true);
} else if( which == 1 ) {
GlobalVariables.getShared().setIsInNorthernHemisphere(false);
}
ToolbarActivity.outfitsFragment.hemisphereSelected();
GlobalVariables.getShared().setHasAskedForHemisphere(true);
}
});
builder.setCancelable(false);
//Create the AlertDialog object and return it
return builder.create();
}
And this is how it's displayed:
new HemisphereDialogFragment().show(getSupportFragmentManager(), "hemisphereDialog");
Another small side question, is there a way to change the text size for the items in the dialog?
You set your alert dialog cancelable to false, but your fragment is still set to cancelable, you need to add setCancelable(false) to your fragment as well.
You should call setCancellable(false) in the Dialog fragment itself not the AlertDialog.Builder.
I have this .xml file with countries and their countrycodes in them. This is how it looks like:
<?xml version="1.0" encoding="UTF-8"?>
<landen>
<land>
<naam>Afghanistan</naam>
<code>AF</code>
</land>
<land>
<naam>Albani�</naam>
<code>AL</code>
</land>
<land>
<naam>Algerije</naam>
<code>DZ</code>
</land>
<land>
</landen>
Now I want people to choose one country out of an list. I though an AlertDialog would be nice to display everything.
The way i get the values out of my xml-file is like this:
protected ArrayList<Land> getLanden() {
ArrayList<Land> lijst = new ArrayList<Land>();
try {
DocumentBuilder builder =DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(getAssets().open("landenlijst.xml"));
NodeList nl = doc.getElementsByTagName("land");
for (int i=0;i<nl.getLength();i++) {
Node node = nl.item(i);
Land land = new Land();
land.land = Xml.innerHtml(Xml.getChildByTagName(node, "naam"));
land.landcode = Xml.innerHtml(Xml.getChildByTagName(node, "code"));
lijst.add(land);
}
Log.d("Gabug","Klaar met parsen");
Log.d("Gabug","Landen: " + lijst);
} catch (Exception e) {
e.printStackTrace();
}
return lijst;
}
And I use this to make my AlertDialog:
public void KiesLandMenu(){
ArrayList<Land> alleLanden = getLanden();
final CharSequence[] items = alleLanden.toArray(new CharSequence[alleLanden.size()]);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Kies land");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
switch (item){
case 0:
break;
case 1:
break;
case 2:
break;
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
I don't know if this works as DDMS returns some bytecode or something when i Log it. And after that it Force Closes because of ArrayStoreException..
Now my question is; is this the best way to do this? if yes, how can I fix the ArrayStoreException? If no, what are better ways to let my user choose a country (a whole new view maybe)?
Furthermore, how can I register what country someone tapped?
EDIT:
I slightly changed the sample code below and I get an NullPointerException now..
public void KiesLandMenu(){
ArrayAdapter<Land> arrAdapter;
ArrayList<Land> alleLanden = getLanden();
arrAdapter = new ArrayAdapter<Land>(this, android.R.layout.simple_list_item_single_choice, alleLanden);
ListView list = (ListView)findViewById(R.layout.lijstview);
list.setAdapter(arrAdapter);
list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> list, View view, int position,
long id) {
Log.e("item clicked", String.valueOf(position));
}
});
}
The NullPointerException is at list.setAdapter(arrAdapter);
Make a layout with a ListView, then set that layout in your onCreate. To make the list, you can do something like:
public class RunTestProject extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); //whatever you want your layout to be
}
// getLanden() implementation goes here
public void KiesLandMenu(){
ArrayList<Land> alleLanden = getLanden();
arrAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_single_choice, alleLanden);
Dialog dialog = new Dialog(this);
dialog.setTitle("Kies land");
dialog.setContentView(R.layout.withList); // The dialog layout
ListView list = (ListView) dialog.findViewById(android.R.id.list); //note that it's not simply findViewById
list.setAdapter(arrAdapter);
list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> list, View view, int position,
long id) {
Log.e("item clicked", String.valueOf(position));
}
});
dialog.show();
}
}
When the user chooses on an item, you can see in the log that the item's position in the array is shown.
Your layout file can be something like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"
/>
</LinearLayout>
You could probably extend AlertDialog and give it a ListView as a view. Then bind the ListView to an ListAdapter which uses your ArrayList.
Edit:
ListView lv = new ListView(context);
ArrayAdapter aa = new ListAdapter(context, viewid, lijst);
lv.setAdapter(aa);
AlertDialog ad = new AlertDialog(context);
ad.setView(lv);
There is a bit more work than that though. You need to specify viewid which is the View representing each item in the ListView.
The sdk reference is very good you know.
new AlertDialog.Builder(this)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.alert_dialog_single_choice)
.setSingleChoiceItems(<ListAdapter> or CharaSequnce[] , 0, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked on a radio button do some stuff */
}
})
.setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked Yes so do some stuff */
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked No so do some stuff */
}
})
.create();
Note :
Please see This link to Api for Bold text mentioned below
.setSingleChoiceItems(CharacterSequnce[] , 0, new DialogInterface.OnClickListener()....
Hope this helps . Thanks :)
