How to customize pop up notifications?

When you click on the image button, pop up notification pops up. How do I customize the "ok" and "cancel" button to instead of using the default look of the buttons, I want to use my own custom ImageButtons as "ok" and "cancel".
Here's my code for pop up notification.
public class Notifications extends AppCompatActivity {
ImageButton Notifications;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notifications);
Notifications = (ImageButton) findViewById(R.id.AllowNotifications);
Notifications.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
AlertDialog.Builder builder = new AlertDialog.Builder(Notifications.this);
builder.setCancelable(false); //False= ONLY way to exist notification is by clicking NO
//True= Exit notification by clicking anywhere on screen outside of notification box.
builder.setTitle("Here is the alert dialog");
builder.setMessage("Here is my message thing");
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int WhichButton) {
dialog.cancel();
}
});
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
});
builder.show();
}
});
}
}
Here's the default pop up notification with the above code:
So instead of there being an "ok" and "cancel" in red color, I want to put the "ok" and "cancel" as my own custom image buttons and I'd want to change the color from red to something else. How do I go about doing this inside the Pop Up notification?

As the documentation says, in the Creating a Custom Layout session, you can create a custom layout and inflate it at your Dialog.
To use another button than the one create by the AlertDialog.Builder you will need to handle the click listener of them.
This is the layout I created to test the solution:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#android:color/white"
android:orientation="vertical"
android:padding="20dp">
<TextView
android:id="#+id/dialogTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Here is the alert dialog"
android:textColor="#android:color/black"
android:textSize="16sp"
android:textStyle="bold"/>
<TextView
android:id="#+id/dialogSubtitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Here is my message thing"/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="32dp">
<Button
android:id="#+id/positiveButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:background="#android:color/transparent"
android:text="OK"
android:textColor="#android:color/holo_red_light"/>
<Button
android:id="#+id/negativeButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="40dp"
android:layout_toStartOf="#id/positiveButton"
android:background="#android:color/transparent"
android:text="Cancel"
android:textColor="#android:color/holo_red_light"/>
</RelativeLayout>
</LinearLayout>
And the code to make it run:
LayoutInflater layoutInflater = LayoutInflater.from(this);
View promptView = layoutInflater.inflate(R.layout.test, null);
final AlertDialog alertD = new AlertDialog.Builder(this).create();
TextView title = (TextView) promptView.findViewById(R.id.dialogTitle);
TextView subtitle = (TextView) promptView.findViewById(R.id.dialogSubtitle);
title.setText("My new Custom Dialog");
subtitle.setText("With everything that I want");
Button positive = (Button) promptView.findViewById(R.id.positiveButton);
Button negativeButton = (Button) promptView.findViewById(R.id.negativeButton);
positive.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// btnAdd1 has been clicked
}
});
negativeButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// btnAdd2 has been clicked
}
});
alertD.setView(promptView);
alertD.show();
This is an screenshot of how it looks like in my phone. Feel free to change the layout in the way it better fits your needs.
Thanks to Vikram that explains it very well in this answers for other question, but I thought that a specific code for your question would be better.

If you want to customize everything, the look of the dialog, add your own buttons, TextViews etc. - you need to make a class that extends DialogFragment and implements View.OnClickListener and you need to create your own layout with two custom made buttons for that. Give them ids and set OnClickListeners
As typed in: https://developer.android.com/reference/android/app/DialogFragment.html
public static class MyDialogFragment extends DialogFragment implements View.OnClickListener {
static MyDialogFragment newInstance() {
return new MyDialogFragment();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.dialog_fragment, container, false);
v.findViewById(R.id.btn_ok).setOnClickListener(this);
return v;
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.btn_ok:
// do something
break;
default:
break;
}
}
}
And from your Activity you do:
void showDialog() {
// Create the fragment and show it as a dialog.
DialogFragment newFragment = MyDialogFragment.newInstance();
newFragment.show(getFragmentManager(), "dialog");
}

How to access EditText placed in a custom layout made for an AlertDialog?

I have made a custom layout for AlertDialog in which there is an EditText.
On click of a button I want to check whether this edittext is empty or filled so that I can carry on further operations.
Here is xml code for custom layout for AlertDialog:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:layout_marginBottom="8dp"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp">
<EditText
android:id="#+id/id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="type here"/>
</android.support.design.widget.TextInputLayout>
</LinearLayout>
Here's what I'm doing with java code:
final AlertDialog.Builder builder = new AlertDialog.Builder(SignUpActivity.this);
builder.setTitle("Choose a unique username");
builder.setView(R.layout.choose_unique_name_dialog);
builder.setPositiveButton("Continue", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
if (uniqueUserName.getText().toString().isEmpty()) {
Snackbar snackbar = Snackbar
.make(coordinatorLayout, "Please choose a unique username", Snackbar.LENGTH_SHORT);
snackbar.show();
} else {
signingUpMethod();
}
}
});
AlertDialog dialog = builder.create();
dialog.show();
So, I want to know how to access this EditText from my MainActivity?
Please let me know.

Try this code,
make it as public static method and you can access from Any other activity
Store edittext value in some static variable and access from another class.

Inflate the layout you're setting to your alertDialog like this
LayoutInflater inflater = this.getLayoutInflater();
View alertDialogView = inflater.inflate(R.layout.your_layout,null);
Access your EditText like this
EditText editText = (EditText) alertDialog.findViewById(R.id.id);

android dialog set icon to title

I have this dialog class and i want to set icon to its title:
public class DialogMealInformation extends Dialog implements
android.view.View.OnClickListener {
Context context;
private TextView tv_information;
private Button b_ok;
private String information;
public DialogMealInformation(Context context, String information) {
// TODO Auto-generated constructor stub
super(context);
this.context = context;
this.information = information;
setContentView(R.layout.dialog_meal_information);
getWindow().setLayout(android.view.ViewGroup.LayoutParams.FILL_PARENT,
android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
setTitle("Info !");
initialize();
}
it tried like this:
setTitle(R.layout.dialog_simple_header);
dialog_simple_header.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<TextView
android:id="#+id/tv_dialog_simple_header_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/tv_information"
android:drawableLeft="#drawable/more_information" />
</LinearLayout>
but the title after that was "res/layout/dialog_simple_header.x" just text, no icon is appear, why please , what is the solution , thanks alot

follow this on any button click or on your onActivity or any place you want this dialog to show. do read my comments every after //
AlertDialog alertDialog = new AlertDialog.Builder(
this).create();
alertDialog.setTitle("TITLE"); // your dialog title
alertDialog.setMessage("Your message"); // a message above the buttons
alertDialog.setIcon(R.drawable.ic_home); // the icon besides the title you have to change it to the icon/image you have.
alertDialog.setButton("Got IT", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) { // here you can add a method to the button clicked. you can create another button just by copying alertDialog.setButton("okay")
}
});
alertDialog.show();
do me a favor and delete this
public DialogMealInformation(Context context, String information) {
// TODO Auto-generated constructor stub
super(context);
this.context = context;
this.information = information;
setContentView(R.layout.dialog_meal_information);
getWindow().setLayout(android.view.ViewGroup.LayoutParams.FILL_PARENT,
android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
setTitle("Info !");
initialize();
}
and add mine instead !

here is a dialog with custom theme and View
final Dialog dialog = new Dialog(mContext,android.R.style.Theme_Translucent_NoTitleBar);
dialog.setContentView(R.layout.dialog_layout_third);
ImageView image = (ImageView) dialog.findViewById(R.id.image2);
//image.setImageResource(R.drawable.ic_launcher);
image.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
dialog.setCancelable(false);
here i'm setting the theme to transparent and then i'm using dialog.SetContentView to add the layout. in my layout i'm using only an imageview and here is my layout for the dialog.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:id="#+id/onetimeedit"
android:visibility="visible"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="#+id/image2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:src="#drawable/drag" />
</RelativeLayout>
</FrameLayout>
you can then add textView as Title just add it to the layout. and or using dialog.setTitle("MyTitleShouldByHere");
hope my example clear it for you, and if that what you want please do accept the answer so other people can get it easy. thanks

Dialog.setTitle(int resId) is used if you wish to set the title text to a string resource.
What you are looking for is what you are already doing - setContentView. In your custom xml there make the title look like what you prefer, or - if you wish to set it at runtime, just get a reference to the ImageView and set it in code.
Hope this helps.

How can I access the EditText field in a DialogBox?

How can I access the EditText field in a DialogBox?

Place your EditText widget into your dialog:
<?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="wrap_content"
android:orientation="vertical">
<EditText
android:id="#+id/myEditText"
android:layout_height="wrap_content"
android:layout_width="fill_parent" />
</LinearLayout>
Then inflate the View from within your Dialog and get the content of the EditText.
private Dialog myTextDialog() {
final View layout = View.inflate(this, R.layout.myDialog, null);
final EditText savedText = ((EditText) layout.findViewById(R.id.myEditText));
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(0);
builder.setPositiveButton("Save", new Dialog.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String myTextString = savedText.getText().toString().trim();
}
});
builder.setView(layout);
return builder.create();
}
After pressing the "Save"-button myTextString will hold the content of your EditText. You certainly need to display the dialog of this example first.

How to keep an alertdialog open after button onclick is fired? [duplicate]

This question already has answers here:
How to prevent a dialog from closing when a button is clicked
(21 answers)
Closed 3 years ago.
The subject kinda says it all.. I'm requesting a PIN code from the user, if they enter it, click the OK Positive Button and the PIN is incorrect I want to display a Toast but keep the dialog open. At the moment it closes automatically.. Sure this is very trivial thing to correct but can't find the answer yet.
Thanks..

You do not need to create a custom class. You can register a View.OnClickListener for the AlertDialog. This listener will not dismiss the AlertDialog. The trick here is that you need to register the listener after the dialog has been shown, but it can neatly be done inside an OnShowListener. You can use an accessory boolean variable to check if this has already been done so that it will only be done once:
/*
* Prepare the alert with a Builder.
*/
AlertDialog.Builder b = new AlertDialog.Builder(this);
b.setNegativeButton("Button", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {}
});
this.alert = b.create();
/*
* Add an OnShowListener to change the OnClickListener on the
* first time the alert is shown. Calling getButton() before
* the alert is shown will return null. Then use a regular
* View.OnClickListener for the button, which will not
* dismiss the AlertDialog after it has been called.
*/
this.alertReady = false;
alert.setOnShowListener(new DialogInterface.OnShowListener() {
#Override
public void onShow(DialogInterface dialog) {
if (alertReady == false) {
Button button = alert.getButton(DialogInterface.BUTTON_NEGATIVE);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do something
}
});
alertReady = true;
}
}
});
Part of this solution was provided by http://groups.google.com/group/android-developers/browse_thread/thread/fb56c8721b850124#

Build a custom dialog with a EditText with the attribute android:password="true" a button, then manually set onClick listener the button, and explicitly choose what to do in it.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minWidth="180dip"
android:digits="1234567890"
android:maxLength="4"
android:password="true"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/Accept"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Accept"/>
</LinearLayout>
</LinearLayout>
Then when you want it to pop up:
final Dialog dialog = new Dialog(RealizarPago.this);
dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("PIN number:");
dialog.setCancelable(true);
Button button = (Button) dialog.findViewById(R.id.Accept);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(password_wrong){
// showToast
} else{
dialog.dismiss();
// other stuff to do
}
}
});
dialog.show();

You can set an OnClickListener as follows to keep the dialog open:
public class MyDialog extends AlertDialog {
public MyDialog(Context context) {
super(context);
setMessage("Hello");
setButton(AlertDialog.BUTTON_POSITIVE, "Ok", (new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// this will never be called
}
});
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (ok) {
// do something
dismiss();
} else {
Toast.makeText(getContext(), "when you see this message, the dialog should stay open", Toast.LENGTH_SHORT).show();
}
}
});
}
}

You can just continue using the dialog you already have, just put an if clause in the onClick() saying
if(pin_check_method){ //pin_check_method should be a boolean returned method
//close the Dialog, then continue
}
else{
//dont put the dialog.dismiss() in here, put instead
Toast.makeText(getApplicationContext(),"Invalid pin, please try again",Toast.LENGTH_LONG).show();
}
Now, to use this code, simply invoke text.setText(""); and put in the text you want here
common error is that when you type in:
TextView text = (TextView) findViewById(R.id.dialog);
you miss that it needs to actually be
dialog.findViewById
and this is regardless of what the name of the dialog is, in my example it just happens to be the same name.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView android:id="#+id/text"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"/>
<Button android:text="Continue"
android:id="#+id/Button01"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_below="#+id/text">
</Button>
</RelativeLayout>

Try this:
final AlertDialog alertDialog = new AlertDialog.Builder(context)
.setView(v)
.setTitle(R.string.my_title)
.setPositiveButton(android.R.string.ok, null) //Set to null. We override the onclick
.setNegativeButton(android.R.string.cancel, null)
.create();
alertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
#Override
public void onShow(DialogInterface dialog) {
Button b = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// TODO Do something
}
});
}
});
alertDialog.show();

Hope This Helps! Good Luck!

Same problem for me in a FragmentDialog. Here's my criminal/elegant solution:
Remove all buttons from the dialog (positive,negative,neutral). Add your buttons from the xml.eg.:
<LinearLayout
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_height="wrap_content">
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:id="#+id/button_cancel"
style="#style/Widget.AppCompat.Button.Borderless.Colored"
android:text="#android:string/cancel"
android:layout_gravity="left"
/>
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:id="#+id/button_ok"
style="#style/Widget.AppCompat.Button.Borderless.Colored"
android:text="#android:string/ok"
android:layout_gravity="right"
/>
</LinearLayout>
And then in your code handle it with:
view.findViewById(R.id.button_ok).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view2) {
if (wannaClose)
dismiss();
else
//do stuff without closing!
}
});
where view is the view assigned to the dialog!
