Android CustomDialog minWidth

I have a CustomDialog (extending Dialog) which is currently set to wrap_content for both width and heigh. Problem is if I set the main text as something really short (say "hello") the dialog gets very small in width. I would like the dialog to always take all the space available, but still have the default margin from the edges of the screen.
I already tried various methods:
setting:
android:layout_width="match_parent"
on the dialog layout, doesn't have any effect.
doing:
int width = (int)(getContext().getResources().getDisplayMetrics().widthPixels*0.90);
getWindow().setLayout(width, LinearLayout.LayoutParams.WRAP_CONTENT);
causes the dialog to go at the start of the screen and doesn't change anything regarding the width
Window window = getWindow();
WindowManager.LayoutParams params = window.getAttributes();
params.horizontalMargin = 10;
params.width = LinearLayout.LayoutParams.MATCH_PARENT;
window.setAttributes(params);
makes the dialog take the whole screen but without any horizonthal margin
putting
<item name="windowMinWidthMajor">100%</item>
<item name="windowMinWidthMinor">65%</item>
in the dialog style has no effect.
how do I accomplish that? Mind that the dialog is used all around the app, so putting any code outside of the dialog class itself is not an option.

Android dialog title box how can i make it smaller

I have an android dialog box and I want to make the Title box smaller preferably to single line because right now it is too large. I been searching around for a fix and can not find it, this is how my dialog title box looks, as you can see I only have 1 line and a lot of padding on top and bottom, how can I fix this?
I have been able to programmatically fix some things by using this
TextView Dialog_Title = (TextView)dialog.findViewById(android.R.id.title);
Dialog_Title.setPadding(2,2,2,2);
Dialog_Title.setMaxHeight(1);
Dialog_Title.setTextSize(18);
Dialog_Title.setTextColor(Color.BLACK);
Any suggestions on this

I think you can use the custom layout for the dialog.
If you want a custom layout in a dialog, create a layout and add it to an AlertDialog by calling setView() on your AlertDialog.Builder object.
By default, the custom layout fills the dialog window, but you can still use AlertDialog.Builder methods to add buttons and a title.
For example, here's the layout file for a dialog.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:src="#drawable/header_logo"
android:layout_width="match_parent"
android:layout_height="64dp"
android:scaleType="center"
android:background="#FFFFBB33"
android:contentDescription="#string/app_name" />
</LinearLayout>
To inflate the layout in your DialogFragment, get a LayoutInflater with getLayoutInflater() and call inflate(), where the first parameter is the layout resource ID and the second parameter is a parent view for the layout. You can then call setView() to place the layout in the dialog.
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
// Inflate and set the layout for the dialog`enter code here`
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.dialog_signin, null))

How to set Android dialog's size to match the dialog's layout size?

I have this xml which defines my dialog:
<?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" >
<TextView android:text="test"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
And this is my dialog:
OverlayItem item = mapOverlays.get(index);
Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.map_menu);
dialog.setCanceledOnTouchOutside(true);
dialog.show();
For some reason my dialog is bigger then my "test" textview (much higher). I want my dialog to be exactly as my text. how can i do that ?

You have to set to dialog the option not to have a title.
So add this: dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
Hope this helps!

I don't have the API in front of me, but I think you need to set the dialog width and height parameters as something like:
dialog.getWindow().setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
You can also set the X,Y coordinates where to show the dialog by playing around with its window and setting its attributes before the show as well.

Remove Title to your dialog then you can decrease your dialog size, or adjust sizes in your layout which is adjusted dialog view.
OverlayItem item = mapOverlays.get(index);
Dialog dialog = new Dialog(context);
// Removing Dialog
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.map_menu);
dialog.setCanceledOnTouchOutside(true);
dialog.show();

Why doesn't fill_parent apply to Dialogs?

My Dialog layout contains:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
The dialog still appears as small as its contents.
I had to do:
dialog.getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
... within the the onCreateDialog callback in order for it to fill the screen.
I can't find any reference to this behaviour on the google dev site.

Answering my own question after much experimenting. Issue has to do with the usage of a Dialog class as opposed to a AlertDialog.
In short, it didn't work because I didn't use the right tools and approach. Solution was to either: continue using a Dialog class but then force it by using d.getWindow() and modifying the dimensions from there OR to use an AlertDialog and inflating the layout as such:
LayoutInflater inflater = (LayoutInflater) getLayoutInflater();
View layout = inflater.inflate(R.layout.about, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
This linked helped a lot: Why does LayoutInflater ignore the layout_width and layout_height layout parameters I've specified?

Custom Alert dialog not centered vertically on Android

I made a custom alert dialog box to be displayed at the end of my game so that the player can enter its name to save it. The problem is when I call show() on the dialog appears but it's not vertically centered! It's a bit lower than it should and no matter what properties I set in the xml or when using setGravity().
I think this is the same problem as the one mentioned here, but no one gave a proper answer.
Thanks for your help.
For more details, here is my code:
AlertDialog.Builder builder;
LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.newrecord,(ViewGroup)findViewById(R.layout.shoot));
builder = new AlertDialog.Builder(this);
builder.setView(layout);
newRecDialog = builder.create();
And here is the code of the first element of the XML layout of newrecord.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:gravity="center"
android:padding="10dp"
android:baselineAligned="true">
Here is the output screenshot:

The bug is described here. The AlertDialog is reserving space for the title/icon panel even where there is neither a title nor an icon.
The fix is, I think, quite simple: it should set the top panel layout to GONE, just as it does for the button panel in the event of there being no buttons. Until that's done, the only workaround is to implement your own Dialog subclass.

If you implement your own dialog the line requestWindowFeature(Window.FEATURE_NO_TITLE) hides the title panel and the dialog is centered on the screen. Maybe it works with a AlertDialog too.

You can use an Activity instead of a custom alert for this. You have to set the theme of activity as dialog in the android manifest file:
android:theme="#android:style/Theme.Dialog"
And you can adjust the activity xml layout as per your need.

android:theme="#android:style/Theme.Dialog"

If you are dealing with any height and width attributes, you must make sure not to alter the height, since it will alter the position, here is a sample.
myProgressDialog.show();
float widthPecent = 0.60f;
//order matters
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int displayWidth = displayMetrics.widthPixels;
//dont do any adjustments to the height. ************************** <<<<<<<<<<
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
layoutParams.copyFrom(myProgressDialog.getWindow().getAttributes());
int dialogWindowWidth = (int) (displayWidth * widthPecent);
layoutParams.width = dialogWindowWidth;
//dont do any changes to the height. ************************** <<<<<<<<<<
myProgressDialog.getWindow().setAttributes(layoutParams);
layoutParams.height = dialogWindowHeight; //comment or remove this line.

set the attribute on your AlertDialog as android:gravity="center" or programmatically as setGravity(Gravity.CENTER). This Gravity is for your layout only not for the display of your mobile. if you use Custom Title its did not look like center vertical.

Not really an answer, but I was having a similar issue. It appears that it is centered, but it is assuming the AlerterDialog has a title set. In my case, I just set a title.

Can you try using AlertDialog.Builder.setCustomTitle(View); instead of setView? We use it because alert dialog looks a bit better than dialog with empty title.

you should use the following line in the xml
firstly remove that padding line from your xml and after that
android:layout_gravity="center"
after this your dialog will appear in center and if you are using the margin from left etc than remove that and also if you are using that
android:layout_width="fill_parent"
than change it with the
android:layout_width="wrap_content"
after that your dialog will be appear in the center.

Try:
newRecDialog.getWindow().getAttributes().gravity = Gravity.CENTER;

You need to disable the window title.
First create a custom style for your dialog (Make sure to use the parent theme that fits your needs):
<style name="CustomDialog" parent="#android:style/Theme.Dialog">
<item name="android:windowNoTitle">true</item>
</style>
Then apply your style to the dialog builder:
AlertDialog.Builder builder;
LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.newrecord,(ViewGroup)findViewById(R.layout.shoot));
builder = new AlertDialog.Builder( new ContextThemeWrapper(this, R.style.CustomDialog));
builder.setView(layout);
newRecDialog = builder.create();
