java - 单击时返回整个字符串的 Spannable 字符串

Question

在 ListView 中的一行上使用 Button 并且能够使单行 Spannable 和数据库中的数据但是当我单击它时返回整个字符串而不是一个单词这里是我的代码来自 MyAdapter 类 将数据库中的值输入到 Listview

public View getView(int i, View view, ViewGroup viewGroup) {
    Realm realm=Realm.getDefaultInstance();
    Word toEdit = realm.where(Word.class)
            .equalTo("id", 10).findFirst();
    int id_to_seperate=toEdit.getLang();

    LayoutInflater inflater= (LayoutInflater) Main.context.getSystemService(Main.context.LAYOUT_INFLATER_SERVICE);
   View row= inflater.inflate(R.layout.layout,viewGroup,false);
    TextView word= (TextView) row.findViewById(R.id.word_name);
    TextView meaning= (TextView) row.findViewById(R.id.word_define);
    Word temp=list.get(i);
    int idz=temp.getId();
    word.setText(temp.getWord());
    if(id_to_seperate==idz){
        String span[] = temp.getMeaning().substring(1).split(" ") ;
        SpannableString ss = new SpannableString(temp.getMeaning().substring(1));
        ClickableSpan spans[] = new ClickableSpan[span.length];
        for(int spanCount = 0 ; spanCount < span.length ; spanCount++){
            spans[spanCount] = new ClickableSpan() {
                @Override
                public void onClick(View textView) {

                    TextView v = (TextView)textView ;
                    String text = v.getText().toString() ;

                    Log.d("View" , text);
                }
            };
        }

        int start = 0 ;
        int end =0;
        try {
            for(int spanCount = 0 ; spanCount <span.length ; spanCount++){
                if(spanCount==0) {
                    end += span[spanCount].length();
                }else{

                    end += span[spanCount].length()+1;
                }
                ss.setSpan(spans[spanCount], start, end , Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
                start += span[spanCount].length()+1;

            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        meaning.setText(ss);
        meaning.setMovementMethod(LinkMovementMethod.getInstance());

    }else {
        meaning.setText(temp.getMeaning().substring(1));
    }
    return row;
}

我能够从列表中的特定行获取结果
对此但是点击功能返回整个句子而不是一个跨度或单词，如果有人能告诉我我犯了什么错误，我将不胜感激
问候

你的代码有问题

TextView v = (TextView)textView ;
String text = v.getText().toString() ;

TextView.getText().toString() 是返回全文。如果你想获得特定的 ClickableSpan 然后使用下面的 ClickableSpan

public class SpecialClickableSpan extends ClickableSpan {

    String text;

    public SpecialClickableSpan(String text){
         super();
         this.text = text;
    }

    @Override
    public void onClick(View widget) {
         Log.d(TAG, "onClick [" + text + "]");
    }
}

替换

for(int spanCount = 0 ; spanCount < span.length ; spanCount++){

    spans[spanCount] = new ClickableSpan() {
        @Override
        public void onClick(View textView) {

            TextView v = (TextView)textView ;
            String text = v.getText().toString() ;
                Log.d("View" , text);
            }
        };
    }

与

for(int spanCount = 0 ; spanCount < span.length ; spanCount++){
    spans[spanCount] =  new SpecialClickableSpan (span[spanCount ]);
}
