Bild mit Android v11 < /p>
Bild mit Android 12 oder höher
, wie ich erwähnt habe, 2 Bilder ist Android 11 und einer Android ist Android 13 In Android 11 Blur funktioniert nicht ordnungsgemäß. Kann mir jemand helfen, dieses Problem mit Renderscript zu beheben? . Der Unschärfeeffekt funktioniert perfekt auf [b] Android 12 und über [/b], wo ich Rendereffect.CreateblureFect () 

verwende. Auf Android 11 und unter , wo ich Renderscript verwende, wird der Unschärfeneffekt entweder nicht richtig angewendet oder überhaupt nicht sichtbar .
Was ich implementiert habe:

< Strong> für Android 12+ → Verwenden von Rendereffect > Für Android 11 und unten → Verwenden von renderscript , um eine verschwommene Bitmap zu generieren und sie als ImageView zu überlösen.
