Question

我正在尝试开发兼容智能手机（一个窗格布局）和平板电脑（两个窗格布局）的应用程序。我的应用程序显示如下：

fragment http://android10.org/images/stories/develoment_1/working_with_fragments_android10_02.png

这个例子很好用。但对于我的应用，我需要在WebView fragment中使用不同的布局。在ListView fragment中选择的每个元素都会在右侧片段中显示特定的布局。

这是我点击元素时调用的代码：

public void onArticleSelected(int position) {
    // The user selected the headline of an article from the
    // HeadlinesFragment

    // Capture the article fragment from the activity layout
    BodyFragment articleFrag = (BodyFragment) getSupportFragmentManager().findFragmentById(R.id.body_fragment);

    if (articleFrag != null) {
        // If article frag is available, we're in two-pane layout...

        // Call a method in the ArticleFragment to update its content
        articleFrag.updateArticleView(position);

    } else {
        // If the frag is not available, we're in the one-pane layout and
        // must swap frags...

        // Create fragment and give it an argument for the selected
        // article
        BodyFragment newFragment = new BodyFragment();

        Bundle args = new Bundle();
        args.putInt(BodyFragment.ARG_POSITION, position);
        newFragment.setArguments(args);
        FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

        // Replace whatever is in the fragment_container view with this
        // fragment,
        // and add the transaction to the back stack so the user can
        // navigate back
        transaction.replace(R.id.fragment_container, newFragment);
        transaction.addToBackStack(null);

        // Commit the transaction
        transaction.commit();
    }
}

我该怎么做？我想将布局动态替换为片段，但这是不可能的。

有人有解决方案吗？
