从非 activity class 打开 SherlockFragment activity？

Question

我正在尝试从非 activity class 打开 SherlockFragment activity 从正常 activity

使用它

Android.app.Activity >> 非ActivityClass >> Sherlock片段Activity

将此从 Activity class 传递给 NonActivityClass 并尝试启动 SherlockFragmentActivity

代码 -

private void changeFragment(Activity act) {

        Fragment profileFrag = new New_ProfileFragment();
        FragmentTransaction transaction = ((SherlockFragmentActivity) act)
                .getSupportFragmentManager().beginTransaction();

        try {
            ((SherlockFragmentActivity) act).getSupportFragmentManager()
                    .popBackStackImmediate(profileFrag.toString(),
                            FragmentManager.POP_BACK_STACK_INCLUSIVE);
        } catch (java.lang.IllegalStateException e) {

        }

        transaction.addToBackStack(profileFrag.toString());
        transaction.replace(R.id.content_frame, profileFrag);
        transaction.commitAllowingStateLoss();
        ((SherlockFragmentActivity) act).getSupportFragmentManager()
                .executePendingTransactions();

    }

我在

中遇到错误

FragmentTransaction transaction = ((SherlockFragmentActivity) act)
                .getSupportFragmentManager().beginTransaction();

异常 - java.lang.ClassCastException: activity 无法转换为 com.actionbarsherlock.app.SherlockFragmentActivity

Answer 1

一个。您是否知道 ActionBarSherlock 已被弃用 2 年？

b。

activity cannot be cast to com.actionbarsherlock.app.SherlockFragmentActivity

几乎可以说明一切。您不能将 android.app.Activity 转换为 SherlockFragmentActivity 因为 from what I can see SherlockFragmentActivity 不会扩展 android.app.Activity 。

c。你要么必须做

activity.getFragmentManager()

或者，如果你必须使用 SupportFragmentManager，你首先 activity 必须是 android.support.v4.app.FragmentActivity 这样你就可以

activity.getSupportFragmentManager()

无论如何，摆脱掉ActionBarSherlock。
