带有自定义标记器的Android MultiAutoCompleteTextView，如whatsapp GroupChat [英] Android MultiAutoCompleteTextView with custom tokenizer like as whatsapp GroupChat

问题描述

我想为@h创建自定义标记器，如同whatspp功能一样（当打开组并写入@然后打开弹出窗口列表，用户可以选择任何用户。也可以删除该字符串@。

我搜索了很多东西。但我发现了像搜索功能一样的推特

解决方案

我的问题得到了解决方案。

我创建了n multiautocompletetextview的自定义视图，并在@sign之后为打开的弹出窗口添加performFiltering方法。

 公共类KcsMultiAutoCompleteTextView扩展MultiAutoCompleteTextView {
 public KcsMultiAutoCompleteTextView（Context context）{
 super（context）; 
} 
 
 public KcsMultiAutoCompleteTextView（Context context，AttributeSet attrs）{
 super（context，attrs）; 
} 
 
 public KcsMultiAutoCompleteTextView（Context context，AttributeSet attrs，int defStyleAttr）{
 super（context，attrs，defStyleAttr）; 
} 
 
 @Override 
 protected void performFiltering（CharSequence text，int start，int end，int keyCode）{
 if（text.charAt（start）== '@'）{
 start = start + 1; 
} else {
 text = text.subSequence（0，start）; 
 for（int i = start; i< end; i ++）{
 text = text +*; 
} 
} 
 super.performFiltering（text，start，end，keyCode）; 
} 
 
} 
  

I want to create custom tokenizer for @ like as whatspp feature(when open group and write @ then open popup for list and user can select any.also user can remove that string of @ .

I have search lots of things.but i have found twitter like search feature Example like twitter,

but in this,when user can write @ then do not show popup window of list. user can write soemthing after @ then based on typing ,popup window will show search result.

I want to show something like this:

Thanks in advanced.

解决方案

I got solution for my question.

i have create own custom view for multiautocompletetextview and add performFiltering method for open popup after @sign.

public class KcsMultiAutoCompleteTextView extends MultiAutoCompleteTextView {
    public KcsMultiAutoCompleteTextView(Context context) {
        super(context);
    }

    public KcsMultiAutoCompleteTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public KcsMultiAutoCompleteTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void performFiltering(CharSequence text, int start, int end, int keyCode) {
        if (text.charAt(start) == '@') {
            start = start + 1;
        } else {
            text = text.subSequence(0, start);
            for (int i = start; i < end; i++) {
                text = text + "*";
            }
        }
        super.performFiltering(text, start, end, keyCode);
    }

}
