SpannableString显示不同的样式

效果图

SpannableString 配置模板的显示样式，在这里记录一下。

1、读取assets文件夹下配置文件的信息，json格式的数据
[{"code": "[sms_order_type]","key": "Order Type"},{"code": "[sms_phone_number]","key":"Phone Number"}]

2、根据正则表达式替换显示

正则替换

采用ImageSpan 替换显示

private void dealExpression(Context context, SpannableString spannableString, Pattern patten, int start,HashMap recordUsedMap) {

Matcher matcher = patten.matcher(spannableString);

    while (matcher.find()) {

String key = matcher.group();

        if (matcher.start() < start) {

continue;

        }

String showStr =editShowMap.get(key);

        if (TextUtils.isEmpty(showStr)) {

continue;

        }

recordUsedMap.put(key,showStr);

        TextView styleTv =new TextView(context);

        styleTv.setText(showStr);

        styleTv.setTextColor(ContextCompat.getColor(context,R.color.app_color_white));

        styleTv.setTextSize(SizeUtils.dp2px(6f));

        styleTv.setBackgroundResource(R.drawable.shape_sms_button_bg_sel);

        styleTv.setMinWidth(SizeUtils.dp2px(100f));

        styleTv.setGravity(Gravity.CENTER);

        styleTv.setPadding(20,5,20,5);

        styleTv.setDrawingCacheEnabled(true);

        styleTv.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));

        styleTv.layout(0, 0, styleTv.getMeasuredWidth(), styleTv.getMeasuredHeight());

        Bitmap bitmap = Bitmap.createBitmap(styleTv.getDrawingCache());

        int end = matcher.start() + key.length();

        ImageSpan imageSpan =new ImageSpan(context, bitmap);

        spannableString.setSpan(imageSpan, matcher.start(), end, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

        styleTv.destroyDrawingCache();

        if (end < spannableString.length()) {

dealExpression(context, spannableString, patten, end,recordUsedMap);

        }

break;

    }

}

在读取配置模板时，再根据正则表达式进行标签替换
