Fragment和Fragment之间的跳转

1:首先创建一个接口

public interface SkipFragment {
void skip(int postion);
}

2:然后设置全局变量

public class GlobalParms {
private static BookrackFragment bookrackFragment; //主页fragment
private static CommunityFragment communityFragment; //公告fragment
private static BookMallFragment bookMallFragment; //书城fragment
private static UserFragment userFragment; //个人fragment
public static SkipFragment mSkipFragment; //改变选中Frangment的接口

/**
 * 获取主页Fragment
 * @return
 */
public static BookrackFragment getBookrackFragment() {
    if (bookrackFragment == null) {
        bookrackFragment = new BookrackFragment();
    }
    return bookrackFragment;
}

/**
 * 公告fragment
 * @return
 */
public static CommunityFragment getCommunityFragment() {
    if (communityFragment == null) {
        communityFragment = new CommunityFragment();
    }
    return communityFragment;
}

/**
 * 书城fragment
 * @return
 */
public static BookMallFragment getBookMallFragment() {
    if (bookMallFragment == null) {
        bookMallFragment = new BookMallFragment();
    }
    return bookMallFragment;
}

/**
 * 个人fragment
 * @return
 */
public static UserFragment getUserFragment() {
    if (userFragment == null) {
        userFragment = new UserFragment();
    }
    return userFragment;
}

/**
 * 设置被选中的Fragment
 * @param skipFragment
 */
public static void setFragmentSelected(SkipFragment skipFragment) {
    mSkipFragment = skipFragment;
}

3:在MainActivity调用setFragmentSelected：

4:fragment调用
