Android的 - 比一的EditText单词不能更大胆 [英] Android - Can't bold more than a word in edittext

问题描述

我有，我想大胆的，我选择文本的EDITTEXT。
我使用的上下文操作栏用按钮来大胆选定的词。
现在的问题是，如果我大胆的一句话我不能大胆其他onesm，如果我从Word中删除的跨度，我不能再添加它。
等是在我写的EDITTEXT，我也用2 SpannableString赶上剩余的文本保持它前加入最终的跨度。

I have an editText in which i want to bold the text that i select. I'm using the Contextual Action Bar with a button to bold a selected word. The problem is that if I bold a word I can't bold the other onesm and if i remove the span from that word, I can't add it again. et is the editText in which i write, and i use also 2 SpannableString to catch the remaining text keeping eventual spans added before on it.

定制的回调

cs1 = new StyleSpan(Typeface.BOLD);

class CustomCallback implements ActionMode.Callback {
public boolean onCreateActionMode(ActionMode mode, Menu menu) {

    //exploiting the CAB

    MenuInflater inflater = mode.getMenuInflater();
    inflater.inflate(R.menu.context_menu, menu);
    menu.removeItem(android.R.id.selectAll);
    return true;
}

public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
    return false;
}

操作添加粗体

public boolean onActionItemClicked(ActionMode mode, MenuItem item) {


    int start = et.getSelectionStart();
    int end = et.getSelectionEnd();




    SpannableStringBuilder s_before,s_next;

    SpannableStringBuilder ssb = new SpannableStringBuilder(et.getText().subSequence(start, end));
    s_before= new SpannableStringBuilder (et.getText().subSequence(0, start));
    s_next= new SpannableStringBuilder (et.getText().subSequence(end, et.length()));



    switch(item.getItemId()) {


    case R.id.bold:

        int a=ssb.getSpanStart(cs1);
        int b=ssb.getSpanEnd(cs1);


        if(a==-1 && b==-1){

            ssb.setSpan(cs1, 0, ssb.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        else{
            ssb.removeSpan(cs1);
        }
        et.setText("");
        et.append(s_before);
        et.append(ssb);
        et.append(s_next);

        return true;

我该如何解决呢？
先谢谢了。

推荐答案

我刚刚把RichEditText库的https： //github.com/kemallette/RichEditText 这增加粗体/斜体/罢工/强调..和一些其他的字体样式功能。它还增加了一个伟大的一堆验证的。

I've just put a RichEditText library https://github.com/kemallette/RichEditText which adds bold/italic/strike/underline.. and a few other font styles functionalities. It also adds a bunch of great validations.

如果不适合你的需求，你需要把重点放在保持跟踪您的跨度，它们是什么类型，以及他们正在调整/重新添加。采取上述图书馆一看RichEditText和RichTextWatcher类。它会给你的文字时，在你的EditText改变什么实际发生的一个更好的主意。

If that doesn't fit your needs, you'll need to focus on keeping track of where your spans are, what type they are and that they're being adjusted/re-added. Take a look at the RichEditText and RichTextWatcher classes in the above library. It'll give you a better idea of what's actually happening when text changes in your EditText.
