在textview中顯示笑臉和在android中編輯文本

你好我正在開發聊天應用程序，我想在其中插入笑臉我沒有太多的想法如何整合和顯示在它你能給我這樣做的建議嗎？在textview中顯示笑臉和在android中編輯文本

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); 
System.out.println("cs is:- " + cs); 
edttxtemoji.setText(cs);

我發現這個代碼，在它使用圖像，這是可行的嗎？還是有另一種解決方案？請給我更好的解決方案，爲此thanx提前

是的還有另一種方式在TextView或EditText內顯示笑臉。使用ImageSpan構建Spannable文本，然後將文本Spannable設置爲TextView或EditText。這是一個post爲相同。

要的EditText

int value=R.id.ic_launcher; 
Drawable Smiley = getResources().getDrawable(value); 
Smiley.setBounds(0, 0, 15, 15); 
SpannableStringBuilder builder = new SpannableStringBuilder(); 
String imgValue = "["+value+"]"; 
builder.append(imgValue); 
builder.setSpan(new ImageSpan(Smiley), builder.length()-imgValue.length(), builder.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 
edit_text.getText().insert(txt.getSelectionStart(), builder);

設置笑臉現在去取笑臉在列表視圖或TextView的

textview.setText(addSmileySpans(context,edit_text.getText())); 
public CharSequence addSmileySpans(Context context, CharSequence msg) { 

    SpannableStringBuilder builder = new SpannableStringBuilder(your_recieved_message); 
    Pattern pattern = Pattern.compile("\\[([^\\[\\]]+)\\]"); 
    if(pattern != null) 
    { 
     Matcher matcher = pattern.matcher(your_recieved_message); 
     int matchesSoFar = 0; 
     while(matcher.find()) 
     { 
      CharSequence cs =matcher.group().subSequence(1, matcher.group().length()-1); 
      int value = Integer.parseInt(cs.toString()); 
      System.out.println("pattern is::"+matcher.group().subSequence(1, matcher.group().length()-1)); 
      int start = matcher.start() - (matchesSoFar * 2); 
      int end = matcher.end() - (matchesSoFar * 2); 
      Drawable Smiley = context.getResources().getDrawable(value); 
      Smiley.setBounds(0, 0,15,15); 
      builder.setSpan(new ImageSpan(Smiley), start + 1, end - 1, 0); 
      builder.delete(start, start + 1); 
      builder.delete(end - 2, end -1); 
      matchesSoFar++; 

     } 
    } 
    return builder; 
}

我認爲這是有點晚了。

public void addSmily() { 
    CharSequence text = myEditText.getText(); 
    int resource = R.drawable.ic_menu_emoticons ; 
    myEditText.setText(getSpannableText(text,resource)); 
} 

private Spannable getSpannableText(CharSequence text, int smilyToAppend) { 
    Spannable spannable = Factory.getInstance().newSpannable(text+" "); 
    ImageSpan smilySpan = new ImageSpan(getApplicationContext(),smilyToAppend); 
    spannable.setSpan(smilySpan, spannable.length()-1, spannable.length(), 0); 
    return spannable; 
}

使用ImageSpan用的EditText
