在Button任意位置加图片效果

通常情况会想到drawableLeft，drawableTop,drawableRight,drawableBotton，这样是可以做，但只能在四个位置。
下面这种办法可以实现任意位置：

import android.app.Activity;import android.graphics.drawable.Drawable;import android.os.Bundle;import android.text.Html;import android.text.Spanned;import android.text.Html.ImageGetter;import android.widget.Button;public class demobutton extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                        ImageGetter imgGetter = new Html.ImageGetter() {                        @Override                        public Drawable getDrawable(String source) {                                Drawable drawable = null;                                drawable = demobutton.this.getResources().getDrawable(                                                Integer.parseInt(source));                                drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),                                                drawable.getIntrinsicHeight());                                return drawable;                        }                };                                Button btn = (Button) findViewById(R.id.button1);                StringBuffer sb = new StringBuffer();                sb.append("<img src=\"").append(R.drawable.button1).append("\"/>").append("<font color=\"6f6f6f\">按钮上加图片效果</font>");;                Spanned span = Html.fromHtml(sb.toString(), imgGetter, null);                btn.setText(span);                sb = null;    }}

采用Spanned也不是什么新鲜事了，呵呵。这里只提供一种思路。不止Button，任意可以显示文字的View都可以这样做。
