Question

在ListView的行上使用Button，并且能够创建单行Spannable和来自数据库的数据，但是当我点击它时返回整个字符串而不是单词来自MyAdapter Class我的代码从数据库输入值Listview

的位置

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得结果这个但是点击功能返回整个句子而不是一个单词或单词，如果有人能告诉我我做了什么错误，我会很感激此致

你的代码中出现了错误

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

TextView.getText（）。toString（）返回全文。如果您想获得具体的ClickableSpan，请使用以下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);
            }
        };
    }

<强>与

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

可点击的字符串在点击
