Ich habe eine Recycler-Ansicht mit verschiedenen View Holders.RecyclerView Recycled ViewHolder Image Ansicht falsche Größe
Einige Ansichtshalter haben Bildansichten, die ich in Glide übertrage, um Bilder anzuzeigen.
Das Problem ist, wenn die Recycler-Ansicht mit dem Recyclen von Ansichten beginnt, entspricht die Breite/Höhe der Bildansicht der der wiederverwendbaren Ansicht, in der sie das Bild falsch anzeigen.
ist hier mein Image:
<ImageView
android:id="@+id/image"
android:layout_marginTop="@dimen/feed_item_margin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"/>
Diese in Glide geben wird
Glide.with(itemView.getContext())
.load(Uri.parse(MediaUtils
.getMedia(feedContent).getMediaUrl()))
.placeholder(R.drawable.placeholder)
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.crossFade().into(image);
Das funktioniert gut, bis die Recyclerview Recycling beginnt so das erste Bild in der recyclerview so aussieht, das ist, wie es ist soll schauen.
jedoch, wenn Sie aus dem Artikel blättern weg und zurückblättern sieht es wie folgt aus:
So ist das Bild verzerrt geworden und ist nicht nicht die volle Breite der Elternteil.
Ich möchte die Bildansicht Inhalt wickeln, da alle Bilder mit unterschiedlichen Höhen usw. sein .. dies zu testen ich diese Zeile holder.setIsRecyclable(false); hinzugefügt Recycling dieser speziellen Halter zu verhindern und alle angezeigten Bilder wie das sollte jedoch Wie erwartet, gab dies den Erschütterungseffekt.
So dann habe ich versucht, wie so die Parameter des Bildansicht in der OnViewRecycled Methode Zurücksetzen:
@Override
public void onViewRecycled(AbstractHolder viewHolder){
super.onViewRecycled(viewHolder);
int position = viewHolder.getAdapterPosition();
IFeedContent content = mFeedContentList.get(position);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.setMargins(0, (int) Utils.dpTopx(mContext,10),0,0);
params.gravity = Gravity.CENTER;
if(isImage(content)){
viewHolder.getImageView().setImageURI(null);
viewHolder.getImageView().setImageDrawable(null);
viewHolder.getImageView().setImageResource(0);
viewHolder.getImageView().setLayoutParams(params);
}
}
Dabei habe ich die params in der XML erstellen, aber es funktioniert nicht. Die Methode isImage() überprüft nur den MIME-Typ des Objekts.
Kann mir jemand helfen? Es ist sehr frustrierend.
Jede Hilfe zu diesem wird geschätzt.
