Sample app

How to use

Please, add the following dependency to your gradle file:

compile 'com.github.fernandospr:overlaydialog:1.0.1'

OverlayDialog inherits from android.app.Dialog, so you can use the same methods from Dialog, for example:

OverlayDialog dialog = new OverlayDialog(this);
dialog.setCancelable(true);
...
dialog.show();
...
dialog.dismiss();

To customize the view for the dialog, you should use:

View customView = LayoutInflater.from(this).inflate(layoutResID, root, false);
...
dialog.setContentView(customView);

To customize the auto dismiss time, you should use:

dialog.setAutoDismissDelayMillis(5000);

To customize the enter/exit animations, you should create a theme and set it in the constructor, for example:

OverlayDialog dialog = new OverlayDialog(this, R.style.TopMessageDialog);
