Android编程实现给Button添加图片和文字的方法

//为按钮添加图片和文字的方法public Spanned getSpan(int id, String s) { ImageGetter imgGetter = new Html.ImageGetter() {  @Override  public Drawable getDrawable(String source) {  // TODO Auto-generated method stub  Drawable drawable = null;  drawable = MainActivity.this.getResources().getDrawable(   Integer.parseInt(source));  drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),   drawable.getIntrinsicHeight());  return drawable;  } }; StringBuffer sb = new StringBuffer(); sb.append("<img src=/"").append(id).append("/"/>")  .append("       ").append("<font>" + s + "</font>"); ; Spanned span = Html.fromHtml(sb.toString(), imgGetter, null); return span;}

button=(Button)findViewById(R.id.button);button.setText(getSpan(R.drawable.button_iv,"按钮"));
