Question

如何在保留其他格式的同时，从edittext中删除粗体样式。尝试将字体设置为正常时，我的应用程序崩溃。将字体设置为粗体不是问题

int startSelection = _etheadertext.getSelectionStart();
    int endSelection = _etheadertext.getSelectionEnd();
    if (startSelection > endSelection) {
        startSelection = _etheadertext.getSelectionEnd();
        endSelection = _etheadertext.getSelectionStart();
    }
    Spannable s = _etheadertext.getText();
    s.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), startSelection, endSelection, 0);
    _etheadertext.setText(s);
    _etheadertext.setSelection(startSelection, endSelection);

    if(_etheadertext.hasSelection()) {

        try {
            if (_etheadertext.getTypeface().getStyle() == Typeface.NORMAL) {


                _etheadertext.setTypeface(null, Typeface.BOLD);
                Toast.LENGTH_SHORT).show();

                chk = false;
            }

            if ((_etheadertext.getTypeface().getStyle() == Typeface.BOLD) && (chk == true)) {

                _etheadertext.setTypeface(null, Typeface.NORMAL);
               // this line crashes the app

                chk = false;
            }


        } catch (Exception e) {

            Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_SHORT).show();

        }

    }

尝试在Bold文件夹中使用strings.xml。

通过代码，您可以这样做：

String sourceString = "<b>" + id + "</b> " + name; mytextview.setText(Html.fromHtml(sourceString));

或：

<string name="test">
     <![CDATA[
 <b>bold!</b> normal
    ]]>
</string>

并像这样调用它：textView.setText(Html.fromHtml(getString(R.string.test)));

当我从edittext中删除字体时，应用崩溃
