getSupportFragmentManager（）方法未定义

Question

I have a Main activity which extends SherlockActivity

The following code seems to be giving me trouble

PopularFragment fragment = new PopularFragment();
            FragmentManager fragmentManager = getFragmentManager();
            fragmentManager.beginTransaction()
                           .replace(R.id.content_frame, fragment)
                           .commit();

I get the error " Type mismatch: cannot convert from android.app.FragmentManager to android.support.v4.app.FragmentManager "

I tried getSupportFragmentManager() but that gives me this error " The method getSupportFragmentManager() is undefined for the type Main.DrawerItemClickListener "

I am playing with the new android navigation drawer, in my libs/ folder I only have support library v13

my fragments imports are import android.support.v4.app.Fragment;

import android.os.Bundle;
import android.support.v4.app.FragmentManager;

How do I solve this issue? Thanks!

Answer 1

You should extend SherlockFragmentActivity not SherlockActivity . And call getSupportFragmentManager instead of getFragmentManager .

Answer 2

I don't know if it is a good practice, But I have changed with newFragment.show(this.getFragmentManager(), "datePicker"); And the datePicker is working.

Answer 3

尝试：

YourActivityClassName.this.getSupportFragmentManager();
