Insert images in Android EditText and respond to click events

Inserting a picture in EditText is basically two ways:

1, by html.fromhtml (.. ) to achieve [Mw_shl_code=java,true]etext.append (html.fromhtml (""+ R.drawable.ohoh +"'/>", Imagegetter,NULL)); [/Mw_shl_code]2, through Imagespan and spannablestring/Spannablestringbuilder. [Mw_shl_code=java,true]spannablestring SS =Newspannablestring (IMGSTR); Drawable drawable=getresources (). getdrawable (r.drawable.bad_smelly); Drawable.setbounds (0,0, Drawable.getintrinsicwidth (), Drawable.getintrinsicheight ()); Imagespan Imagespan=NewImagespan (drawable, imagespan.align_baseline); Ss.setspan (Imagespan,0, Imgstr.length (), spannable.span_exclusive_exclusive); Etext.append (ss);

The complete code is affixed below,
Click events are implemented by adding clickablespan.
