问题描述

如何从文字的EditText和笑脸转换成String?

根据下列code我加入笑脸/ Emojis在EDITTEXT,但如何从文字的EditText /笑脸成字符串格式。

  ImageGetter imageGetter =新ImageGetter(){
        公众可绘制getDrawable(字符串源){
            绘制对象D = getResources()。getDrawable(
                    R.drawable.happy);
            d.setBounds(0,0,d.getIntrinsicWidth(),d.getIntrinsicHeight());
            返回D组;
        }
    };

    CS = Html.fromHtml(
            &所述; IMG SRC ='
                    + getResources()
                            .getDrawable(R.drawable.happy)
                    +'/>中,imageGetter,空);
    edttxtemoji.setText(CS);
 

解决方案

请使用以下的功能。

 公共静态Spannable getSmiledText(上下文的背景下,文本字符串){
          SpannableStringBuilder建设者=新SpannableStringBuilder(文本);
          INT指数;对于(指数= 0;指数< builder.length();指数++){
            对于(进入<字符串,整数>输入:emoticons.entrySet()){
              INT长度= entry.getKey()长度()。
              如果(指数+长度GT; builder.length())
                继续;
              如果(builder.subSequence(索引,索引+长度)的ToString()。等于(entry.getKey())){
                builder.setSpan(新ImageSpan(上下文,entry.getValue()),指数,指数+长度,
                    Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                指数+ =长度 -  1;
                打破;
              }
            }
          }
          返回建设者;
        }
 

下面的情绪code ...

 私有静态最后的HashMap<字符串,整数>图释=新的HashMap<字符串,整数>();
        静态{
          emoticons.put(8),R.drawable.s1);
          emoticons.put(: - &安培;,R.drawable.s2);
          emoticons.put(> :-),R.drawable.s3)......};
 

和使用的setText

  tv_msg_send.setText(getSmiledText(getApplicationContext(),edt_msg.getText()的toString()));
 

How to Get text and smiley from edittext into String?

Using Following Code I was Add Smiley/Emojis in Edittext but how to get text/smiley from edittext into String Format.

    ImageGetter imageGetter = new ImageGetter() {
        public Drawable getDrawable(String source) {
            Drawable d = getResources().getDrawable(
                    R.drawable.happy);
            d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
            return d;
        }
    };

    cs = Html.fromHtml(
            "<img src='"
                    + getResources()
                            .getDrawable(R.drawable.happy)
                    + "'/>", imageGetter, null);
    edttxtemoji.setText(cs);
解决方案

Please use following function.

public static Spannable getSmiledText(Context context, String text) {
          SpannableStringBuilder builder = new SpannableStringBuilder(text);
          int index;for (index = 0; index < builder.length(); index++) {
            for (Entry<String, Integer> entry : emoticons.entrySet()) {
              int length = entry.getKey().length();
              if (index + length > builder.length())
                continue;
              if (builder.subSequence(index, index + length).toString().equals(entry.getKey())) {
                builder.setSpan(new ImageSpan(context, entry.getValue()), index, index + length,
                    Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                index += length - 1;
                break;
              }
            }
          }
          return builder;
        }

following for emotions code...

private static final HashMap<String, Integer> emoticons = new HashMap<String, Integer>();
        static {
          emoticons.put("8-)", R.drawable.s1);
          emoticons.put(":-&", R.drawable.s2);
          emoticons.put(">:-)", R.drawable.s3).....};

and settext using

tv_msg_send.setText(getSmiledText(getApplicationContext(), edt_msg.getText().toString()));
