在这种情况下，我的Switch语句应该以break退出还是返回x？

在我的应用程序中，用户可以选择文本并使用图像上显示的选项设置文本的样式。在查看代码时，我想知道我所有switch语句的case语句是否应该，break或者return true/false是否有任何影响？我可以看到，通过使用Log.d();该方法break可以切换开关，而在开关中使用return停留

因此，在这种情况下，发生的情况是否重要？

Switch情况下的方法：

@Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {


        switch (item.getItemId()) {

            case R.id.textcolor:

                f3 = ColorPickerDialogFrag2.newInstance(3, Color.WHITE);
                f3.setStyle(android.support.v4.app.DialogFragment.STYLE_NORMAL, R.style.AppTheme);
                f3.show(fragmentManager, "d");

                f3.setListener(this);

                break;


            //--------------------BOLD----------------------------
            case R.id.bold:

                styleSpans = str.getSpans(selectionStart, selectionEnd, StyleSpan.class);

                for (int i = 0; i < styleSpans.length; i++) {
                    if (styleSpans[i].getStyle() == android.graphics.Typeface.BOLD) {
                        str.removeSpan(styleSpans[i]);
                        exists = true;
                    }
                }

                if (!exists) {

                return true;
