像这样使用 -String htmlString = "<img src='ic_launcher'><i>Welcome to<i> <b><a href='http://android-coding.blogspot.com'>Android Coding</a></b>";&nbsp;@Override&nbsp;protected void onCreate(Bundle savedInstanceState) {&nbsp; super.onCreate(savedInstanceState);&nbsp; TextView htmlTextView = new TextView(this);&nbsp; setContentView(htmlTextView);&nbsp; htmlTextView.setText(Html.fromHtml(htmlString, new Html.ImageGetter(){&nbsp; &nbsp;@Override&nbsp; &nbsp;public Drawable getDrawable(String source) {&nbsp; &nbsp; Drawable drawable;&nbsp; &nbsp; int dourceId =&nbsp;&nbsp; &nbsp; &nbsp; getApplicationContext()&nbsp; &nbsp; &nbsp; .getResources()&nbsp; &nbsp; &nbsp; .getIdentifier(source, "drawable", getPackageName());&nbsp; &nbsp; drawable =&nbsp;&nbsp; &nbsp; &nbsp; getApplicationContext()&nbsp; &nbsp; &nbsp; .getResources()&nbsp; &nbsp; &nbsp; .getDrawable(dourceId);&nbsp; &nbsp; drawable.setBounds(&nbsp; &nbsp; &nbsp; 0,&nbsp;&nbsp; &nbsp; &nbsp; 0,&nbsp;&nbsp; &nbsp; &nbsp; drawable.getIntrinsicWidth(),&nbsp; &nbsp; &nbsp; drawable.getIntrinsicHeight());&nbsp; &nbsp; return drawable;&nbsp; &nbsp;}&nbsp; }, null));&nbsp; htmlTextView.setMovementMethod(LinkMovementMethod.getInstance());&nbsp;}}
