ImageView im Java Code "erstellen"

Hallo zusammen,

ich habe folgendes Problem:

ich möchte, dass mein Programm, wenn ein bestimmtes Ereigniss eintritt, eine neue ImageView "erstellt", d.h. dass diese ImageView nicht schon vorher im XML-Layout vorhanden sein soll, sondern erst dann erzeugt werden soll.

Danke schonmal im Vorraus

Das Ding soll im Layout ja an irgendeine Stelle.
Packe dort ein passenden (Relative)Layout (mit android:id="@+id/imageviewcontainer" oder so) hin.
Das kannst Du Dir dann per findViewById(R.id.imageviewcontainer) holen.
Dort steckst Du mittels addView() deinen erzeugen ImageView reintun.
Anschließend rufst Du auf dem "Container" eine entsprechende Invalidierung (postInvalidate() oder so) auf.

Danke für die schnelle Antwort!

werde es direkt ausprobieren

Wahrscheinlich bin ich einfach nur zu doof, aber bei mir funktioniert es irgendwie nicht.

Muss die ImageView schon in einem anderen Layout vorhanden sein?

Bei mir stürzt er jedes mal bei addView ab.

In so einem Fall wäre ein LogCat nützlich.

Hier der LogCat:

hoffe das hilft.

Da stehts.
Der neue View hat den falschen Parent.
Klingt so als hättest Du die Reihenfolge von setContentView und View-Erzeugung verbockt

Danke jetzt läufts

was man nicht alles lernen kann (z.B. dass man nächstes Mal zuerst ins LogCat schauen sollte )
