本文介绍了一种允许DialogFragment响应外部触摸的方法。通过在对话框创建后设置窗口标志，可以使DialogFragment接收其边界之外的触摸事件，并清除背景暗化标志以改善外观。此外，还提供了一个隐藏对话框标题的技巧。

Allow outside touch for DialogFragment

In order to do that, a flag of the Window that allows the outside touch should be turned on and for the good appearance the background dim flag should be cleared.
Since it must be done after dialog is created, I've implemented it via the Handler.

@Override
public void onViewCreated(final View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    // This is done in a post() since the dialog must be drawn before locating.
    getView().post(new Runnable() {

        @Override
        public void run() {

            Window dialogWindow = getDialog().getWindow();

            // Make the dialog possible to be outside touch
            dialogWindow.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
                    WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
            dialogWindow.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

            getView().invalidate();
        }
    });
}

At this moment the outside touch is possible.

In case we want to make it nicer and without the frame, the following code can be added:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Hide title of the dialog
    setStyle(STYLE_NO_FRAME, 0);
}
