Die Tage, Monate und Jahre sollen durch nach oben bzw. nach unten
scrollen veränderbar sein. Hierzu habe ich folgendes Layout geschrieben:

Code: 
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

    android:gravity="center" >

    <LinearLayout

Leider funktioniert das Scrolling des Gesture-Detectors nicht wirklich. Er reagiert nur manchmal. Ich scrolle und scrolle über die Layouts und nichts passiert, und dann plötzlich von jetzt auf gleich gehts wie geschmiert. Dann will ich auf einem anderen Layout scrollen und es geht wieder ewig nicht.

Ich habe leider keine Ahnung was da schief läuft, deshalb muss ich euch um Hilfe bitten.
 
Ich habe das Ganze mal auf ein etwas kleineres Problem herunter gebrochen.
Das Layout sieht nun wie folgt aus:

Code: 
	<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
		xmlns:tools="http://schemas.android.com/tools"
		android:layout_width="match_parent"
		android:layout_height="match_parent"
		android:layout_gravity="center"
		android:fillViewport="true"
		android:gravity="center" >
						
		<LinearLayout
			android:id="@+id/date_selection_layout_from_day"
			android:layout_width="match_parent"
			android:layout_height="wrap_content"
			android:layout_gravity="center"
			android:gravity="center"
			android:orientation="vertical" >

			<EditText
				android:id="@+id/date_selection_edittext_from_day"
				android:layout_width="100dp"
				android:layout_height="50dp"
				android:layout_gravity="center"
				android:background="@drawable/custom_background"
				android:gravity="center"
				android:inputType="number"
				android:maxLines="1"
				android:nextFocusDown="@+id/date_selection_edittext_from_month"
				android:paddingBottom="5dp"
				android:paddingTop="5dp"
				android:singleLine="true"
				android:textColor="@color/textcolorprimary"
				android:textSize="20sp" />
		</LinearLayout>

	</ScrollView>

Also ein EditText in einem LinearLayout in einer ScrollView. Wenn ich nun
folgendes mache:

Code: 
this.editTextFromDay = (EditText) view.findViewById(R.id.date_selection_edittext_from_day);
this.editTextFromDay.setOnTouchListener(this);

Funktioniert alles ohne Probleme. Ich möchte allerdings, dass die Touch Events vom LinearLayout verarbeitet werden, deshalb habe ich folgendes
getan:

Code: 
this.layoutFromDay = (LinearLayout) view.findViewById(R.id.date_selection_layout_from_day);
this.layoutFromDay.setOnTouchListener(this);

this.editTextFromDay = (EditText) view.findViewById(R.id.date_selection_edittext_from_day);
this.editTextFromDay.setEnabled(false);

Und nun, obwohl das EditText deaktiviert ist, fängt es anscheinend die
Touch Events ab. Immer wenn ich über das EditText scrolle passiert
gar nichts, wenn ich über das Layout scrolle funktioniert alles. Ich möchte
also, dass die Touch Events aller Kinder des LinearLayouts irgendwie zum
LinearLayout weitergeleitet werden. Wie kann ich das tun?

Ich kann leider onInterceptTouchEvent nicht verwenden, da mein sich
mein Code in einem DialogFragment befindet.
