So sehen Sie den Inhalt der Bildansicht von oben

Question

Hey Leute Ich habe dieses Layout, wo es eine Touch-Bild-Ansicht aus dem Internet geladen ist, wenn das Telefon im Hochformat ist alles in Ordnung, aber wenn in der Landschaft der mittlere Teil von das Bild erscheint (ich habe es von Anfang an, um nach oben zu sehen), wie es möglich ist programmatisch

hier ist mein Layout, um nach oben:

Try Setscroll verwenden:

public void setScrollPosition(float focusX, float focusY) { 
     setZoom(normalizedScale, focusX, focusY); 
    }
