java - 应用程序在平板电脑上运行，但在智能手机上崩溃

Question

这是 Activity 中的代码。 fragment 发生变化。应用程序可以在平板电脑上运行，但可以在智能手机上运行(请参阅评论行)。尝试/捕获不起作用。平板电脑上的 Android 版本为 4.2，智能手机上的 Android 版本为 4.4。

这是什么？

The code:

 @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        // Check to see if we have a frame in which to embed the details
        // fragment directly in the containing UI.
        View detailsFrame = getActivity().findViewById(R.id.details);

        mDualPane = detailsFrame != null && detailsFrame.getVisibility() == View.VISIBLE;

        if (savedInstanceState != null) {
            // Restore last state for checked position.
            mCurCheckPosition = savedInstanceState.getInt("curChoice", 0);
        }

        Fragment f = map.get(mCurCheckPosition);
        f = new DeviceUARTFragment(getActivity() , ftD2xx);

        map.put(mCurCheckPosition, f);
        Bundle args = new Bundle();
        args.putInt("index", mCurCheckPosition);
        f.setArguments(args);

        currentFragment = f;

        FragmentTransaction ft = getFragmentManager().beginTransaction();
        ft.replace(R.id.details, f);
        ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
        ft.commit(); /* here application crashes */

        old_index = currect_index;
    }

Answer 1

我不确定，但此屏幕上似乎没有id“详细信息”(R.id.details)。

您使用R.id.details来替换您的Fragment，但是，看起来，您在这一行中写了错误的id

    ft.replace(R.id.details, f);

您可能对平板电脑使用不同的布局。尝试设置正确的 id。

希望对您有帮助。
