Properly closing custom dialog - android

I'd like to easily display custom-style popups across the whole application.
For that in my Utils class I created this static method:
public static Dialog showStyledPopup(Context context, String sHeader, String sMessage,
String sBtn0Text, View.OnClickListener onClick0,
String sBtn1Text, View.OnClickListener onClick1,
String sBtn2Text, View.OnClickListener onClick2)
{
Dialog dialog = new Dialog(context, R.style.dialog_style_no_bg);
dialog.setContentView(R.layout.popup);
dialog.setCancelable(false);
TextView txtHeader = (TextView)dialog.findViewById(R.id.txt_popup_header);
if (null == sHeader)
{
txtHeader.setVisibility(View.GONE);
}
else
{
txtHeader.setText(sHeader);
txtHeader.setTypeface(App.fontHeader);
}
TextView txtMessage = (TextView)dialog.findViewById(R.id.txt_popup_message);
txtMessage.setText(sMessage);
txtMessage.setTypeface(App.fontCommon);
Button btn0 = (Button)dialog.findViewById(R.id.btn_popup_0);
btn0.setVisibility(View.VISIBLE);
btn0.setText(sBtn0Text);
btn0.setTypeface(App.fontCommon);
btn0.setOnClickListener(onClick0);
if (null != onClick1)
{
Button btn1 = (Button)dialog.findViewById(R.id.btn_popup_1);
btn1.setVisibility(View.VISIBLE);
btn1.setText(sBtn1Text);
btn1.setTypeface(App.fontCommon);
btn1.setOnClickListener(onClick1);
}
if (null != onClick2)
{
Button btn2 = (Button)dialog.findViewById(R.id.btn_popup_2);
btn2.setVisibility(View.VISIBLE);
btn2.setText(sBtn2Text);
btn2.setTypeface(App.fontCommon);
btn2.setOnClickListener(onClick2);
}
dialog.show();
return dialog;
}
popup.xml:
<?xml version="1.0" encoding="utf-8"?>

</style>
The caller is supposed to pass the View.OnClickListeners.
To be able to close the dialog, the caller must have Dialog dialog field which is then used in the OnClickListener to dismiss the dialog, e.g.:
this.dialog = Utils.showStyledPopup(this, null, getString(R.string.STR_ENABLE_SOUND_AND_MUSIC_Q),
getString(R.string.STR_YES), new View.OnClickListener()
{
#Override
public void onClick(View v)
{
doToggleSound();
doToggleMusic();
dialog.dismiss();
dialog = null;
}
}, getString(R.string.STR_NO), new View.OnClickListener()
{
#Override
public void onClick(View v)
{
dialog.dismiss();
dialog = null;
}
});
The problem is that for some reason in rare cases the dialog field gets reset while the popup is still shown. I can't reproduce this, but got a few crash reports because of this in the field.
Has someone tried to do the same?
The activity has it's orientation fixes to landscape, so onCreate should never get called in-between to reset dialog variable.
I don't like the idea of storing the reference to the dialog, but there is just no way to use a final variable in this case, because it gets a value after it should be passed to the OnClickListener.
My question is similar to Android close custom dialog but the problem there is also not solved, at least as I want it (as 1 method in Utils).
I've seen onCreate() being called on DellStreak device at weird times, so this might be just some device-specific issue (PMP5080BRU)

The solution would be to declare Dialog dialog as class field, declare it at class level.
EDIT
Try this solution too. Have the dialog as class field in the Utils class. Do not return the dialog object from the method, instead use it to initialize the dialog variable. The use a getter method (or try accessing directly though not recommended) of dialog variable. This is kinda dirty solution, but it might work for you too.

android alertdialog theme inconsistency error

I have an alert dialog which popups when you click a button in my app. The code is pretty simple and can be seen below:
final String[] options = {"Bar Graph", "Pie Chart", "Text Summary"};
AlertDialog.Builder builder = new AlertDialog.Builder(myActivity.this);
builder.setTitle("Choose a summary");
builder.setIcon(R.drawable.summaryicon);
builder.setItems(options, ... );
See below an image of what it looks like. This is good.
However, strangely sometimes when I build my app on the emulator the theme of the alert dialog changes and looks like this instead:
I cannot imagine what would be causing this random change in a seemingly unpredictable way.
I have tried using this line to set the theme manually, but it seems to have no effect.
ContextThemeWrapper themedContext = new ContextThemeWrapper( AnalysisActivity.this, android.R.style.ThemeOverlay_Material_Dialog_Alert );
AlertDialog.Builder builder = new AlertDialog.Builder(themedContext);
...
I am confused and looking for a way to set the theme manually or ensure it doesn't change from the default.
I can't entirely tell if the rest of my app also experiences the same theme change because most has all been overridden by custom code, but I don't believe it is changing. Any ideas would be welcome.
Note: this alternate theme looks like an older theme so perhaps there is some version issue?
try this code...
step-1: create layout file of your alert dialog(this layout is your designed alertDialog)
step-2: and use this code
public void displayAlertDialog() {
LayoutInflater factory = LayoutInflater.from(this);
final View alertDialogView = factory.inflate(R.layout.alert_dialog, null);
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setView(alertDialogView);
alertDialogView.findViewById(R.id.bar_graph).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your business logic
alertDialog.dismiss();
}
});
alertDialogView.findViewById(R.id.pie_chart).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your business logic
alertDialog.dismiss();
}
});
alertDialogView.findViewById(R.id.text_summary).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your business logic
alertDialog.dismiss();
}
});
alertDialog.show();
}
Along with Dinesh Sarma's answer the code I have now implemented to create the alertdialog activity can be seen here.
It creates a layout that looks like this:
Use this layout code in a file called alert_dialog.xml:

DialogPreference in Full Screen Width

I created a custom dialog preference in my Android application, but I can not figure out how to get the dialog which is displayed to span the complete width of the display.
image of dialog with too much space on left and right side
I found many proposed solutions to get a normal Dialog in full screen mode
Android get full width for custom Dialog
https://gist.github.com/koocbor/88db64192638bff09aa4
http://blog.jimbaca.com/force-dialog-to-take-up-full-screen-width/
But setting the attributes via getWindow does not work:
#Override
public Dialog getDialog() {
Dialog dialog = super.getDialog();
dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
// or
// dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
return dialog;
}
And applying a full screen theme to my dialogs root element didn't do the job neither:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
[...]
android:theme="#style/FullscreenTheme">
Moreover I'm not able to access the onCreate Method (at least I don't know how) of the Dialog, to set the style there.
Did anyone had the same problem and figured out a solution for this very specific issue?

Edit:
Actually I only want the dialog to span over the full width of the screen, not the height. If I would use a additional PreferenceFragment (as the DialogPreference is already embedded in a PreferenceFragment ) the "Dialog" (aka Fragment) would take the complete width and height (i guess).
I already implemented a solution without a DialogPrefrence, that works but is not exactly elegant
using just a normal EditTextPreference
adding an onPreferenceClickListener to this preference in my SettingsFragment Code
the ClickListener displays a simple Dialog
Example:
Preference preference = findPreference(EXAMPLE_PREFRENCE);
if (preference != null) {
preference.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
#Override
public boolean onPreferenceClick(Preference preference) {
// showDialog();
}
});
But as I have a lot of preferences which will display dialogs the code for the dialog creation and display bloads the SettingsFragment and makes it nearly unreadable. Therefore I thought it would be a nice solution to put the responsibility of displaying the dialog and handling the preference values to the Preference and the XML layout.
Unfortunately I got stuck with the "full width issue" mentioned above.
Note: fixed the code of getDialog as I tested different versions (also in combination with the xml theme set)
Finally I did find a solution for this problem:
Fetch the AlertDialog of the Preference in showDialog method
#Override
protected void showDialog(Bundle state) {
super.showDialog(state);
CustomDialogPreference.makeDialogFullScreen((AlertDialog) getDialog());
}
make it span the complete width:
public static void makeDialogFullScreen(AlertDialog d) {
NLog.d(TAG, "makeDialogFullScreen enter ");
if (d != null) {
ViewGroup.LayoutParams params = d.getWindow().getAttributes();
if (params != null) {
params.width = WindowManager.LayoutParams.MATCH_PARENT;
params.height = WindowManager.LayoutParams.WRAP_CONTENT;
d.getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
}
}
}
Try this in the onResume of your dialog.
// Store access variables for window and blank point
Window window = getDialog().getWindow();
Point size = new Point();
// Store dimensions of the screen in `size`
Display display = window.getWindowManager().getDefaultDisplay();
display.getSize(size);
// Set the width of the dialog proportional to 75% of the screen width and height
window.setLayout((int) (size.x * 0.75), (int) (size.y * 0.75));
window.setGravity(Gravity.CENTER);
// Call super onResume after sizing
Adjust accordingly for 100%. It works great for a dialogFragment. Haven't tried it for your case though.
Wait, you're not looking for the bog-standard 'Pref settings user options appear in a dialog' thing are you? That's almost definitely already done in AndroidStudio's add activity...> Settings Activity in boiler plate, check it out, or look for sample settings apps
Anyway, I do actually have a fullscreen dialog in my app, although it purposely doesn't fill the full screen, and I actually use an activity with some fragments now instead.
Personally I think this is what your problem is, I remember having this exact issue when I first needed a dialog like this. You should just use activities and have up navigation (if you want a full screen "popup" type thing you could use the Navigation pattern that makes the home/up button an 'X' instead of a '<');
Or anything else, you don't need to have a dialog explicitly, and if you do then extend activity or dialog and get what you want.
Here's my activity stuff in case it's any use
my theme:
<style name="AppTheme.FullScreenDialog"
parent="#style/Theme.AppCompat.Light.Dialog">
<item name="windowActionBar">true</item>
<item name="windowNoTitle">true</item>
</style>
my onCreate gist:
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
...
requestWindowFeature(Window.FEATURE_NO_TITLE);
...
super.onCreate(savedInstanceState);
setContentView(getConcreteContentView());
ButterKnife.bind(this);
setUpUIComponents();
...
}

What should I use instead of custom dialog in android api less 20

I wrote an application which have to call dialog to get name. I need the custom view in dialog so I used .setContentView(). But in android with api less 20 I have problems with displaying it.
This is calling dialog:
public void setName(View v) {
nameDialog = new Dialog(this);
//using our dialog
nameDialog.setContentView(R.layout.new_name);

OK the answer is quite simple: Use the android.support.v7.app.AlertDialog
Your setName will have to look like this then:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.new_name, null);
builder.setView(dialogView);
EditText text = (EditText) dialogView.findViewById(R.id.form2_dialog_name);
//if we have previous name we show it
if (haveName) {
text.setText(((Button) findViewById(R.id.form2_name_button)).getText());
}
//request focus and call keyboard for input name
text.requestFocus();
text.selectAll();
AlertDialog dialog = builder.create();
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
dialog.show();
I guess you will have to play a little with your layout file because the buttons are quite a bit too far away but I think this will be just a little problem ;)

I know, I am late to answer this 2 yrs old question, but this one is for those who don't know a correct approach yet....
Use a Custom Dialog as (everyone has suggested).
Use a RelativeLayout as the main layout of custom_dialog.xml as you will have to float that cancel button on top corner (right/left) of the main window.
custom_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="400dp"
android:layout_alignParentTop="true"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="15dp"
android:background="#F4F4F4">
<!--Main Body of your custom dialog-->
</RelativeLayout>
<LinearLayout
android:id="#+id/llTop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:orientation="vertical">
<ImageButton
android:id="#+id/btnCancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/btnBookK"
android:background="#null"
android:src="#drawable/ic_close" />
</LinearLayout>
</RelativeLayout>
In your custom dialog code use following line to make it transparent:
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
customDialog.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:id="#+id/llTop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:paddingBottom="10dp"
>
<Button
android:id="#+id/btnClose"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:text="Close"
/>
</LinearLayout>
<ImageView
android:src="#drawable/ic_launcher"
android:layout_width="130dp"
android:layout_height="130dp"
android:text="Close"
android:layout_centerInParent="true"
android:layout_below="#+id/llTop"
/>
</RelativeLayout>
I have created 1 method whenever you want to display dialog just call this method.
private Dialog dialog; // class variable
private void showDialog
{
dialog = new Dialog(Activity.this); // always give context of activity.
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.customDialog);
Button dialogButton = (Button) dialog.findViewById(R.id.btnClose);
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
dialog.dismiss();
}
});
dialog.show();
}
Yo have to create custom dialog
import android.app.Dialog;
import android.content.Context;
public class CustomDialog extends Dialog
{
public CustomDialog(Context context)
{
super(context);
setContentView(R.layout.dialog);
}
}
create dialog.xml file. design according to your requirment.

Custom theme of all dialogs in an app

Is there any similar theme generator as HoloColors or Action Bar Style Generator which would help us change theme of Dialogs and AlertDialogs in our apps?
My app uses Holo theme and I managed to change style of views such as EditTexts and Buttons but they remain unchanged when they appear in a Dialog. I would also like to change color of the blue line under a title.
I've found a few question and answers related to this topic but they practically say it's not even possible. I cannot believe it isn't.
At least for the AlertDialog it is possible. here i posted my solution of a function which is called at some point (for example button click) in your code and creates an alert dialog own layout over your screen.. the layout is a normal layout.xml which you can define the way you want. works perfect for me!
private void showAddUserGeneratedStationDialog() {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(
AmplifyActivity.this);
LayoutInflater inflater = getLayoutInflater();
//inflate your layout.xml
alertDialog
.setView(inflater.inflate(R.layout.dialog_add_station, null));
//show dialog over activity screen
final AlertDialog ad = alertDialog.show();
//put actions to your ui-elements
Button cancelBtn = (Button) ad
.findViewById(R.id.list_user_generated_cancelBU);
cancelBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ad.cancel();
}
});
Button doneBtn = (Button) ad
.findViewById(R.id.list_user_generated_doneBU);
doneBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//get sth from your layout f.e. some textInput
String stationUrl = ((TextView) ad
.findViewById(R.id.list_user_generated_stationURLInput))
.getText().toString();
// did some other things
ad.dismiss();
}
});
}
and my layout.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_user_generated_addStationDialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#99000000"
android:clickable="true"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="300dp"
android:layout_height="200dp"
android:padding="10dp"
android:background="#000"
android:orientation="vertical" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/list_user_generated_cancelBU"
style="#style/ButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|right"
android:text="#string/cancel" />
<TextView
style="#style/AmplifyHeadlineElement"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:text="#string/list_userGenerated_addStation" />
<Button
android:id="#+id/list_user_generated_doneBU"
style="#style/ButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|right"
android:text="#string/done" />
</LinearLayout>
<EditText
android:id="#+id/list_user_generated_stationURLInput"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:layout_marginTop="10dp"
android:background="#FFF"
android:ems="10"
android:hint="#string/list_userGenerated_addUrlExample"
android:inputType="textNoSuggestions" >
</EditText>
<!-- MORE BUT I DELETED IT FOR BETTER OVERVIEW -->
</LinearLayout>
