Question

这是Activity中的代码。片段改变了。应用程序可在平板电脑上运行，但可以在智能手机上使用（请参阅注释行）。尝试/捕捉不起作用。平板电脑的Android版本为4.2，智能手机的版本为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，但似乎没有 id ＆＃34; 详情＆＃34; （R.id.details）在此屏幕上。

您使用R.id.details替换Fragment，但是，看起来，您在此行中输入了错误的ID

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

可能，您为平板电脑使用不同的布局。尝试设置正确的ID。

希望，它会对你有帮助。

应用程序在平板电脑上工作但在智能手机上崩溃
