您可以根据需要添加任意数量的ImageSpans Spannable.只需遵循您链接的代码所规定的概念即可.你可能也想用它SpannableStringBuilder.

Drawable happySmiley = mContext.getResources().getDrawable(R.drawable.happy);
happySmiley .setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
Drawable sadSmiley = mContext.getResources().getDrawable(R.drawable.sad);
sadSmiley .setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());

SpannableStringBuilder builder = new SpannableStringBuilder();
builder.append("Some text [happy_smiley_anchor]");
builder.setSpan(new ImageSpan(happySmiley), builder.length()-"[happy_smiley_anchor]".length(), builder.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
builder.append(". Some more text [sad_smiley_anchor]");
builder.setSpan(new ImageSpan(sadSmiley), builder.length()-"[sad_smiley_anchor]".length(), builder.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

edittext.setText(builder);

显然你可以使用你喜欢的任何锚文本/字符 - ImageSpan插入时它会被替换.它甚至可以使用空的字符/字符串,但我没有尝试.
