Ich arbeite im Android Studio und triyng, um ein Foto aus einem Verzeichnis von meinem Handy zu importieren und es auf einem ImageView zu setzen.Mein BildView funktioniert nicht
In meiner ersten Aktivität habe ich versucht, das Foto mit der Kamera zu speichern, und ich habe versucht, die URI vom Foto zu speichern. Das funktioniert.
In einer anderen Aktivität habe ich versucht, diesen URI zu importieren, aber mein ImageView ändert sich nicht. Der Compiler hat den Ort vom Foto aus gesehen, also denke ich funktioniert, aber die Bildansicht kann das Foto nicht importieren ...
Können Sie mir helfen?
