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();

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.
I am using AlertDialog but android adds white space at the bottom of AlertDialog.
I found that the problem is happening when i use the
alertDialog.getWindow().setLayout(600, 400);
The creation of AlertDialog is done like :
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setView(layout);
alertDialog = builder.create();
alertDialog.show();
alertDialog.getWindow().setLayout(600, 400); //Controlling width and height.
I show the AlertDialog in a Fragment class and Fragment class belongs to AppCompatActivity.
How to remove this white space ?
You should use
alertDialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
to wrapping things use wrap_content in your xml file.
Check one more thing, have you used any layout element with static height or not. Should use wrap_content in all parent xml elements.
You can also use android:background="#80000000" // transparent code in parent most layout element.
Basically I have a RecyclerView in my AlertDialog (I've tried both the AppCompat one and the one from here) and when the list only has a few items the dialog is still as tall as it can be. Is there something I can do to fix this?
My layout is this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></android.support.v7.widget.RecyclerView>
</LinearLayout>
and I'm adding it to the AlertDialog like this:
LayoutInflater myLayout = LayoutInflater.from(context);
final View dialogView = myLayout.inflate(R.layout.list, null);
dialog.setView(myLayout);
How can I make it wrap_content?
Here is another similar question I found. Using #PiyushMishra's solution:
alertDialog.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(alertDialog.getWindow().getAttributes());
lp.width = 150;
lp.height = 500;
lp.x=-170;
lp.y=100;
alertDialog.getWindow().setAttributes(lp);
I was able to control the dialog's size. You could get creative with this and determine the size needed based on the # of list items.
I'm sorry I'm unsure how to get the Dialog to wrap_content. You may have some luck using a custom dialog instead of AlertDialog.
I have a dialog with a custom theme:
final Dialog d = new Dialog(this,android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
This makes my dialog background transparent.
Now the problem is if I let the normal theme(style.dialog) it is centered in my screen but now it has no layout and is in the upper left corner of my screen. Is there a way to programmatically center the dialog?
I didn't actually find a programatic solution to my problem, instead in my customdialog.xml I put the main layout into a RelativeLayout with fill_parent for height/width and then put the layout atribute centerInParent="true".
construct your dialog by extends Dialog,
override the style & content(by setContentView)
I'd like to show a Dialog that occupies as much screen space as possible.
So, here's a sample:
AlertDialog dialog = new AlertDialog.Builder(ctx)......create();
Window w = dialog.getWindow();
WindowManager.LayoutParams lp = w.getAttributes();
lp.width = 320;
lp.height = 480;
w.setAttributes(lp);
Problem is, this doesn't change a thing. Why?
TIA.
I don't know how to do exactly what you're wanting, but isn't this mostly defeating the purpose of a Dialog? Why not just create a custom Activity and use the Dialog theme if you're just wanting it to look dialog-ey.
You need to change the window layout parameters AFTER setContentView. Anything you do to the window before then (size/location-wise) will be tossed out when you call setContentView.
http://devstream.stefanklumpp.com/2010/07/android-display-dialogs-in-fullscreen.html
You need to add minWidth and minHeight attributes in the Dialog's xml layout file. E.g. your screen size is 800 * 480, then set android:minWidth="800dip", android:minHeight="400dip"
