Use the Settings dialog box to set the size, location, style, and settings on the Android desktop pop-up dialogs

First step: Create a dialog box

Mydialog mydlg=new Mydialog (context);

Step two: Get the window Instance of the dialog box, control the location, size and pop-up scene of the dialog box through the window instance.

Window Dlgwindow=mydly.getwindow ();

Setting the final display location of the dialog box

Dlgwindow.setgravity (Gravity.top);

The parameters can be gravity.top (top),Gravity.button (bottom),gravity.left (left),Gravity.right (right) , Gravity.center (centered) and their combination

Setting the dialog box size

By getting the size of the screen, it's easier to set it up in proportional ways

First Get WindowManager instance

WindowManager m = (WindowManager) getsystemservice (Context.window_service);

Display d = m.getdefaultdisplay (); Get screen width, Gao Yun

Windowmanager.layoutparams p = dlgwindow.getattributes (); Gets the current parameter value of the dialog box

P.height = (int) (D.getheight () * 0.5); Height set to 0.5 of the screen

P.width = (int) (D.getwidth () * 1); Width set to entire screen width

P.alpha = 0.5f; Set the transparency of a dialog box

Dlgwindow.setattributes (P);//

The Settings dialog box pops up on the desktop

Mydlg.getwindow (). SetType (WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);//Set up here to display the dialog box in the desktop

Sets the style of the window;

Styling a dialog box with a style file

Here are some of the most commonly used tags

<item name= "Android:windowfullscreen" >true</item> <!--fill Screen--

<item name= "Android:windowframe" > @null </item>: Dialog windowframe box is not

<item name= "Android:windowisfloating" >TRUE</ITEM>: Whether it appears on the activity

<item name= "android:backgrounddimenabled" >FALSE</ITEM>: whether the background is blurry or not

<item name= "Android:windowanimationstyle" > @style/xxx_ani</item>: Setting Popup and Vanishing animations for dialog boxes

Other:

Set the click outside of the dialog box to close the dialog box

Mydlg.setcanceledontouchoutside (TRUE);

Animate animated Settings

Mydlg.getwindow (). Setwindowanimations (R.style.dialog_ani);
