Android: Display custom dialog in center of the container

Question

How to display custom dialog as a center of the container?

Dialog customdialog = new Dialog(this,android.R.style.Theme_Translucent_NoTitleBar); 
Window window = customdialog.getWindow();
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
window.setGravity(Gravity.CENTER);

R.style.Theme_Translucent_NoTitleBar - is used to remove border for cutomdialog. Once i used this line the dialog will appear at the topleft corner of the tablet?

Can anyone help me to solve this issue?

Answer 1

Change the fill_parent to wrap_content.I hope this will be the issue the dialog appear at the corner of the activity.It takes the space of whole layout.So changing this may help you to get what you realy wanted.

Window window = customdialog.getWindow();
window.setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
window.setGravity(Gravity.CENTER);

Answer 2

I added this to the dialog's custom style and it worked fine.

<item name="android:layout_gravity">center</item>

My dialog's width and height are set to wrap_content. The style's parent is

parent="@android:style/Theme.Light"

Answer 3

I will go for this piece of code:

        WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
        Window window = dialog.getWindow();
        lp.copyFrom(window.getAttributes());
        //This makes the dialog take up the full width
        lp.width = WindowManager.LayoutParams.MATCH_PARENT;
        lp.height = WindowManager.LayoutParams.MATCH_PARENT;
        window.setAttributes(lp);

Where dialog, is the dialog object to be shown. Inside of the layout of the dialog you can define the view of the layout as you wish: centered or not.

I use this code and the problem solved

Window window = alertDialog.getWindow();
window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
window.setGravity(Gravity.CENTER);
