I have searched through all the answers about dismissing a Dialog onTouchOutside, however, I am using DialogFragment in my application. How can I achieve dismissing the DialogFragment when user clicks outside the DialogFragment's region.
I have examined Dialog's source code for setCanceledOnTouchOutside
public void setCanceledOnTouchOutside(boolean cancel) {
if (cancel && !mCancelable) {
mCancelable = true;
}
mCanceledOnTouchOutside = cancel;
}
There's another function which may be interesting which is isOutOfBounds
private boolean isOutOfBounds(MotionEvent event) {
final int x = (int) event.getX();
final int y = (int) event.getY();
final int slop = ViewConfiguration.get(mContext).getScaledWindowTouchSlop();
final View decorView = getWindow().getDecorView();
return (x < -slop) || (y < -slop)
|| (x > (decorView.getWidth()+slop))
|| (y > (decorView.getHeight()+slop));
}
but I couldn't figure out a way to make use of these for DialogFragment
In addition to these I have examined the state of the application with hierarchyviewer and as I understand it, I can only see the region of the dialog and not the outsied part of it (I mean the remaining part of the screen after the DialogFragment).
Can you suggest a way of implementing this setCanceledOnTouchOutside for DialogFragment and if possible with a sample code?
The answer is pretty simple:
MyDialogFragment fragment = new MyDialogFragment(); // init in onCreate() or somewhere else
...
if ( fragment.getDialog() != null )
fragment.getDialog().setCanceledOnTouchOutside(true); // after fragment has already dialog, i. e. in onCreateView()
See http://developer.android.com/reference/android/app/DialogFragment.html#setShowsDialog%28boolean%29 for more info about dialogs in DialogFragments.
