推荐答案

您可以添加任意多的 ImageSpan s到一个 Spannable ，只要你喜欢。只要按照所要链接的code中提出的概念。你可能想使用 SpannableStringBuilder 了。

You can add as many ImageSpans to a Spannable as you like. Just follow the concept laid out by the code you're linking. You probably want to use a SpannableStringBuilder too.

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，你可以使用任何你喜欢的锚文本/字符 - ImageSpan 插入时，它被替换。它甚至有一个空字符/字符串的工作，但我没有尝试。

Obviously you can use any anchor text/character you like - it gets replaced when the ImageSpan is inserted. It might even work with an empty char/string, but I didn't try that.
