I'm tried to blur background using this post:
https://stackoverflow.com/a/21278278/10837992.
It's work good but i have a little problem with the size of the dialog.
I'm created custom layout :
I'm changed the realization of the method.
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.alert_dialog_layout, null);
builder.setView(dialogView);
TextView title = dialogView.findViewById(R.id.Title);
TextView desc = dialogView.findViewById(R.id.Desc);
title.setText("Title");
desc.setText("Desc");
AlertDialog alert = builder.create();
Bitmap map = new BlurUtils().takeScreenShot(getActivity());
Bitmap fast = new BlurUtils().fastblur(map, 50);
final Drawable drawable = new BitmapDrawable(getResources(), fast);
alert.getWindow().setBackgroundDrawable(drawable);
alert.show();
While running this method, the size of the Dialog is cropped:
Screenshoot:
Ok , I find a solution:
Just added Theme to AlertDialog.Builder.
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(),android.R.style.Theme_DeviceDefault_Light_NoActionBar_Fullscreen);

I'm showing a dialog in an Activity.
I set the background color to transparent by using this code
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
And the dialog background shows transparent, but problems arise when I test my app on some other device.
It shows a white background instead of transparent.
I am not getting how the problem can happen by using the same code in different devices.
Here is my code
final AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.update_client, null);
****** some code*******
dialogBuilder.setView(dialogView);
alertDialog = dialogBuilder.create();
alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
// alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
alertDialog.setCanceledOnTouchOutside(false);
alertDialog.show();
}
Try to use Dialog instead of AlertDialog and your problem will get solved.

How to implement a custom AlertDialog View
(11 answers)
Closed 7 years ago.
I have an EditText in a .xml file with LinearLayout and want to add it as the setView() parameter on an AlertDialog. Is this possible? Here's what I've tried:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
final EditText input = new EditText(this);
builder.setView(input);
But the dialog is blank when launched. What am I doing wrong?
Use it like this
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.your_layout, null);
builder.setView(dialogView);
AlertDialog alertDialog = builder.create();
alertDialog.show();
using dialogView you can get your EditText like this
EditText editText = (EditText) dialogView.findViewById(R.id.your_edit_text);
It might help
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = getLayoutInflater();
builder.setView(inflater.inflate(R.layout.YourLayout, null));
AlertDialog ad = builder.create();
How do I add a popup dialog over the call screen? I'll be using the BroadcastReceiver to listen for incoming calls and show it. I need an idea about how to write an activity that allows a dialog over an incoming call. Also, how do I make the dialog movable to any part of the screen? I already have the BroadcastRceiver implemented and performing other functions, so I could just use an intent and start the activity from this BroadcastRceiver
start an activity, then use AlertDialog Builder from that activity to prompt a dialog
set custom view to customize the dialog appearence
Try this
AlertDialog.Builder builder = new AlertDialog.Builder(context.getApplicationContext());
LayoutInflater inflater = LayoutInflater.from(context);
View dialogView = inflater.inflate(R.layout.caller_dialog, null);
ImageView button = dialogView.findViewById(R.id.close_btn);
builder.setView(dialogView);
final AlertDialog alert = builder.create();
alert.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
alert.getWindow().setType(WindowManager.LayoutParams.TYPE_PHONE);
alert.setCanceledOnTouchOutside(true);
alert.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
Window window = alert.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setGravity(Gravity.TOP);
lp.copyFrom(window.getAttributes());
//This makes the dialog take up the full width
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
window.setAttributes(lp);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//close the service and remove the from from the window
alert.dismiss();
}
});
When I tried to set the result of my program to a textView in a dialog box , the app force closed. I made the dialog box by linking an xml which has a textview and it is this textview that I tried to update.
AlertDialog.Builder alert = new AlertDialog.Builder(this);
LayoutInflater factory = LayoutInflater.from(this);
resultOne=(TextView)findViewById(R.id.resultOne); //resultone is a textview in xml dialog
resultOne.setText("hello"); //this code is making the app close
final View textEntryView = factory.inflate(R.layout.dialog, null);
alert.setView(textEntryView);
alert.show();
Change the order so that you acess the View's children after inflating it. You will also need to use textEntryView to find the id, like so:
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.dialog, null);
resultOne=(TextView)textEntryView.findViewById(R.id.resultOne); //resultone is a textview in xml dialog
resultOne.setText("hello");
alert.setView(textEntryView);
alert.show();
I want the message text within my dialog box to be center aligned.
Of course, you can always set the gravity of the original text view. This allows you to not have to worry about formatting and padding.
For example
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Title");
builder.setMessage("Message");
builder.setPositiveButton("OK", null);
AlertDialog dialog = builder.show();
// Must call show() prior to fetching text view
TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);
Create your own TextView object and then supply it to popup builder as View:
AlertDialog.Builder popupBuilder = new AlertDialog.Builder(this);
TextView myMsg = new TextView(this);
myMsg.setText("Central");
myMsg.setGravity(Gravity.CENTER_HORIZONTAL);
popupBuilder.setView(myMsg);
You can control all other text parameters (style, color, size ...). To control margins you may programatically create LinearLayout, set LayoutParams, and then put TextView into it.
Building off of Chase's answer, here's how to also center the title. I think this is the easiest way. Why android doesn't center by default or make it a simple constructor param is beyond me.
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("My Title");
builder.setMessage("My message");
builder.setPositiveButton("OK", listener);
AlertDialog dialog = builder.show();
// Must call show() prior to fetching views
TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);
TextView titleView = (TextView)dialog.findViewById(context.getResources().getIdentifier("alertTitle", "id", "android"));
if (titleView != null) {
titleView.setGravity(Gravity.CENTER);
}
we can use as like.
public static void showAlert(Activity activity, String message) {
TextView title = new TextView(activity);
title.setText("Your Title Here");
title.setPadding(10, 10, 10, 10);
title.setGravity(Gravity.CENTER);
title.setTextColor(Color.WHITE);
title.setTextSize(20);
AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setCustomTitle(title);
builder.setMessage(message);
builder.setCancelable(false);
builder.setNegativeButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.show();
TextView messageText = (TextView)alert.findViewById(android.R.id.message);
messageText.setGravity(Gravity.CENTER);
messageText.setTextColor(Color.RED);
}
you can try this code
public void Info(){
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Info Aplication");
builder.setIcon(R.drawable.info_adp);
builder.setMessage("Jakarta Hospital");
builder.setCancelable(false);
builder.setPositiveButton("Exit", null);
AlertDialog dialog = builder.show();
TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);
}
without using textview.
worked for me.
styles.xml
<style name="CustomAlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:gravity">center</item>
</style>
Alertdialog
final AlertDialog builder = new AlertDialog.Builder(activity,
R.style.CustomAlertDialog)
try this in your TextView:
android:gravity = "center_vertical|center"
