富文本使用，TextView末尾接一个图片

使用
final Drawable drawable = getResources().getDrawable(R.mipmap.qietu);
TextViewUtils.addDrawableInEnd(textview, mActivity, drawable, "XXXXXXXXXXXXXX路-XXXXXXXXXXX路方向");

public class TextViewUtils {    /**     * 富文本添加图片到末尾 并自动匹配高度     *     * @param textView     * @param context     * @param drawable     */    public static void addDrawableInEnd(TextView textView, Activity context, Drawable drawable, String str) {        if (drawable == null) {            return;        }        TextPaint paint = textView.getPaint();// 获取文本控件字体样式        Paint.FontMetrics fm = paint.getFontMetrics();        int textFontHeight = (int) Math.ceil(fm.descent - fm.top) + 2;// 计算字体高度座位图片高度        int imageWidth = drawable.getIntrinsicWidth() * textFontHeight                / drawable.getIntrinsicHeight();// 计算图片根据字体大小等比例缩放后的宽度        drawable.setBounds(0, AppTools.dip2px(context, 1), imageWidth,                textFontHeight);// 缩放图片  也可根据实际需求        ImageSpan span = new ImageSpan(drawable, ImageSpan.ALIGN_BOTTOM); //   ImageSpan.ALIGN_BASELINE放置位置        String space = " ";        str = str + space;        int strLength = str.length();        SpannableString ss = new SpannableString(str);        ss.setSpan(span, strLength - 1, strLength, Spannable.SPAN_INCLUSIVE_INCLUSIVE);        textView.setText(ss.subSequence(0, strLength));    }}

  public static int dip2px(Context context, float value) {        return (int) (context.getResources().getDisplayMetrics().density * value + 0.5f);    }
