我将一个spannable对象分成3个部分,做不同的操作,然后我需要合并它们.
Spannable str = editText.getText();
Spannable selectionSpannable = new SpannableStringBuilder(str, selectionStart, selectionEnd);
Spannable endOfModifiedSpannable = new SpannableStringBuilder(str, selectionEnd, editText.getText().length());
Spannable beginningOfModifiedSpannable = new SpannableStringBuilder(str, 0, selectionStart);
我该怎么做？我还没有找到所需的方法或构造函数.
