Android 在文本视图中显示位图

我试图在文本视图中显示位图。下面的代码使用R.drawable.bitmap\u名称在textview中显示位图。如何在SpannableStringBuilder中传递位图？谢谢

 SpannableStringBuilder builder = new SpannableStringBuilder();
            builder.append(text).append(" ");
            builder.setSpan(new ImageSpan(MyActivity.this, R.drawable.image_1 ), builder.length() - 1, builder.length(), 0);
            myTv.setText(builder);

例如：

builder.setSpan(new ImageSpan(yourBitmap), builder.length() - 1, builder.length(), 0);

ImageSpan

具有以下构造函数：

new ImageSpan(Bitmap b)
new ImageSpan(Bitmap b, int verticalAlignment)
new ImageSpan(Context context, Bitmap b)
new ImageSpan(Context context, Bitmap b, int verticalAlignment)
