Question

我有一个framelayout，其中有几个子节点，但是当我用片段替换它时，它不会替换它，而是与framelayout xml文件重叠。我已经阅读了一些文档，但我找不到合适的文档。

小帮助会很棒。谢谢！

public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == R.id.action_notification) {
            Fragment fragment = NotificationFragment.newInstance();
            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
            transaction.replace(R.id.content_frame, fragment).commit();}
        return super.onOptionsItemSelected(item);
    }

xml文件：

请尝试以下代码：

public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == R.id.action_notification) {
            FragmentManager fm = getFragmentManager();
            fm.beginTransaction().replace(R.id.content_frame, new NotificationFragment()).commit();
        return super.onOptionsItemSelected(item);
    }

希望这有帮助。
