     return PersonInfo.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position;

    @Override

     LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View view = inflater.inflate(R.layout.person_layout,parent,false);

    public void setPhone(String phone) { 
     this.phone = phone; 
    } 

    public String getEmail() { 
     return email;

    public void setEmail(String email) { 
     this.email = email; 
    } 
} 

Answer 1

Zeigen Sie Ihren Adapter Code. Zuerst prüfen days. days hält keine Tage. days sollte int Typ sein.

Überprüfen Sie unten LOGIC.

String[] splited = PersonInfo.get(position).getPhone().split("\\s+"); //65 days 
String str_Days=splited[0]; //65 
int days = Integer.valueOf(str_Days); 

if (days<=120) 
{ 
     Your_LayoutOBJ.setBackgroundColor(Color.parseColor("#54D66A")); 
} 
else 
{ 
     Your_LayoutOBJ.setBackgroundColor(Color.parseColor("#FFFFFF")); 
} 

FYI

Your_LayoutOBJ ist Ihr RootLayout.

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/rootLayout" 
    > 

    ..... 

</RelativeLayout> 

Deklarieren LIKE Textview and Set background color.

Answer 2

Dieser Code in Adapter oder anzeigen Halter hinzufügen, wenn Sie verwenden RecyclerView

if(yourObject.days>120){ 
    rootLayout.setBackgroundColor(ContextCompat.getColor(mContex‌​t, R.color.green)); 
    }else{ 
    rootLayout.setBackgroundColor(ContextCompat.getColor(mContex‌​t, R.color.red)); 
    }
