there are two ways of doing it either you can use XML or Java for it  If it s static and requires no changes then you can initialize in XML      android drawableLeft   drawable cloud up      android drawablePadding  5sp    Now if you need to change the icons dynamically then you can do it by  calling the icons based on the events          textViewContext setText  File Uploaded    textViewContext setCompoundDrawablesWithIntrinsicBounds R drawable uploaded  0  0  0

You can use setCompoundDrawablesWithIntrinsicBounds int left  int top  int right  int bottom  set 0 where you don t want images Example for Drawable on the left  TextView textView    TextView  findViewById R id myTxtView   textView setCompoundDrawablesWithIntrinsicBounds R drawable icon  0  0  0    Alternatively  you can use setCompoundDrawablesRelativeWithIntrinsicBounds to respect RTL LTR layouts   Tip  Whenever you know any XML attribute but don t have clue about how to use it at runtime  just go to the description of that property in developer doc  There you will find Related Methods if it s supported at runtime   i e  For DrawableLeft

Using Kotlin   You can create an extension function or just use setCompoundDrawablesWithIntrinsicBounds directly   fun TextView leftDrawable  DrawableRes id  Int   0       this setCompoundDrawablesWithIntrinsicBounds id  0  0  0      If you need to resize the drawable  you can use this extension function   textView leftDrawable R drawable my icon  R dimen icon size   fun TextView leftDrawable  DrawableRes id  Int   0   DimenRes sizeRes  Int        val drawable   ContextCompat getDrawable context  id      val size   resources getDimensionPixelSize sizeRes      drawable  setBounds 0  0  size  size      this setCompoundDrawables drawable  null  null  null      To get really fancy  create a wrapper that allows size and or color modification   textView leftDrawable R drawable my icon  colorRes   R color white   fun TextView leftDrawable  DrawableRes id  Int   0   DimenRes sizeRes  Int   0   ColorInt color  Int   0   ColorRes colorRes  Int   0        val drawable   drawable id      if  sizeRes    0            val size   resources getDimensionPixelSize sizeRes          drawable  setBounds 0  0  size  size            if  color    0            drawable  setColorFilter color  PorterDuff Mode SRC ATOP        else if  colorRes    0            val colorInt   ContextCompat getColor context  colorRes          drawable  setColorFilter colorInt  PorterDuff Mode SRC ATOP            this setCompoundDrawables drawable  null  null  null
