在textview中显示笑脸和在android中编辑文本

你好我正在开发聊天应用程序，我想在其中插入笑脸我没有太多的想法如何整合和显示在它你能给我这样做的建议吗？在textview中显示笑脸和在android中编辑文本

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);

我发现这个代码，在它使用图像，这是可行的吗？还是有另一种解决方案？请给我更好的解决方案，为此thanx提前

是的还有另一种方式在TextView或EditText内显示笑脸。使用ImageSpan构建Spannable文本，然后将文本Spannable设置为TextView或EditText。这是一个post为相同。

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);

设置笑脸现在去取笑脸在列表视图或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; 
}

我认为这是有点晚了。

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
