Question

以下是我在DrawerItemClickListener.java中的代码。 getFragmentManager（）和getActionBar（）为红色，表示无法解析方法。我该如何解决这个问题？

公共类DrawerItemClickListener实现ListView.OnItemClickListener {

private String[] mNavigationDrawerItemTitles;
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    selectItem(position);
}

private void selectItem(int position) {

    Fragment fragment = null;

    switch (position) {
        case 0:
            fragment = new CreateFragment();
            break;
        case 1:
            fragment = new ReadFragment();
            break;
        case 2:
            fragment = new HelpFragment();
            break;

        default:
            break;
    }

    if (fragment != null) {
        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();

        mDrawerList.setItemChecked(position, true);
        mDrawerList.setSelection(position);
        getActionBar().setTitle(mNavigationDrawerItemTitles[position]);
        mDrawerLayout.closeDrawer(mDrawerList);

    } else {
        Log.e("MainActivity", "Error in creating fragment");
    }
}

}

Answer 1

使用

FragmentManager fragmentManager = ((YourFragmentActivity)activity).getFragmentManager();

而不是

FragmentManager fragmentManager = getFragmentManager();

Answer 2

如果您在getSupportFragmentManager()，我认为您应该尝试Activity。也许它会有所帮助
