My app, particularly the MainActivity suffers from some lag when I scroll through the RecyclerView. I tried to fix OverDraw as much as I can. This is what my OverDraw screenshot looks like:activity_main.xml:<?xml version=1.0 encoding=utf-8?><RelativeLayout xmlns:android=http://schemas.android.com/apk/res/androidxmlns:tools=http://schemas.android.com/toolsandroid:layout_width=match_parentandroid:layout_height=match_parentxmlns:ads=http://schemas.android.com/apk/res-autoandroid:background=@drawable/backgroundandroid:paddingBottom=@dimen/activity_vertical_marginandroid:paddingLeft=@dimen/activity_horizontal_marginandroid:paddingRight=@dimen/activity_horizontal_marginandroid:paddingTop=@dimen/activity_vertical_margintools:context=.ChordsList.ChordsListActivity><RelativeLayout    android:id=@+id/layout_top    android:layout_width=match_parent    android:layout_height=wrap_content>    <ImageView        android:id=@+id/logo        android:layout_width=match_parent        android:layout_height=100dp        android:scaleType=fitStart        android:src=@drawable/icon_verde_acqua_tras/>    <ImageButton        android:id=@+id/menu        android:background=@color/trans        android:layout_width=40dp        android:layout_height=40dp        android:src=@drawable/tasto_menu        android:scaleType=fitCenter        android:layout_centerVertical=true        android:layout_alignParentEnd=true        android:layout_marginTop=20dp        android:onClick=showMenu/>    <ImageButton        android:id=@+id/search        android:background=@color/trans        android:layout_width=40dp        android:layout_height=40dp        android:src=@drawable/tasto_ricerca        android:scaleType=fitCenter        android:layout_centerVertical=true        android:onClick=onSearchButtonPressed        android:layout_toStartOf=@id/menu        android:layout_marginTop=20dp />    <ImageButton        android:id=@+id/tuner        android:background=@color/trans        android:layout_width=40dp        android:layout_height=40dp        android:layout_centerVertical=true        android:onClick=onTunerButtonPressed        android:src=@drawable/tuner        android:scaleType=fitCenter        android:layout_toStartOf=@id/search        android:layout_marginTop=20dp /></RelativeLayout><android.support.v7.widget.RecyclerView    android:layout_width=wrap_content    android:layout_height=wrap_content    android:id=@+id/chords_recycler    android:layout_below=@+id/layout_top    android:layout_alignParentStart=true    android:layout_marginTop=25dp /></RelativeLayout>row.xml:<?xml version=1.0 encoding=utf-8?><RelativeLayout xmlns:android=http://schemas.android.com/apk/res/androidandroid:layout_width=match_parent android:layout_height=wrap_content><TextView    android:id=@+id/nome    android:layout_width=wrap_content    android:layout_height=wrap_content    android:textAllCaps=true    android:layout_centerVertical=true    android:textSize=25sp    android:layout_marginTop=10dp    android:fontFamily=sans-serif-condensed    android:textStyle=bold    android:textColor=@color/black /><ImageView    android:id=@+id/immagine_accordo    android:layout_width=130dp    android:layout_marginTop=5dp    android:layout_height=100dp    android:scaleType=fitCenter    android:layout_alignParentEnd=true/></RelativeLayout>Assuming that the problem is OverDraw (please tell me if it's not), how can I improve it further? I need everything that is in the Image, so I cannot remove the background.As suggested by Ivanhoe, OverDraw does not seem to be a problem. The Adapter class and binding could be.Adapter class:public class ChordsListAdapter extends RecyclerView.Adapter<ChordsListAdapter.MyViewHolder> {private ArrayList<Accordo> chordsList;Context c;public class MyViewHolder extends RecyclerView.ViewHolder {    public TextView nome; //note    public ImageView immagine;    public MyViewHolder(View view) {        super(view);        nome = (TextView) view.findViewById(R.id.nome);        immagine = (ImageView) view.findViewById(R.id.immagine_accordo);    }}public ChordsListAdapter(Context c, ArrayList<Accordo> chordsList) {    this.chordsList = chordsList;    this.c = c;}@Overridepublic MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.row, parent, false);    return new MyViewHolder(itemView);}@Overridepublic void onBindViewHolder(MyViewHolder holder, int position) {    Accordo chord = chordsList.get(position);    holder.nome.setText(chord.getName());    holder.immagine.setImageResource(chord.getImage()[0]);}@Overridepublic int getItemCount() {    return chordsList.size();}}
