mMenuTitles根据position 怎么调转到相应的fragment?

Question

/**
* 切换主视图区域的Fragment
*
* @param position
*/
private void selectItem(int position) {
Fragment fragment = new ContentFragment();
Bundle args = new Bundle();
switch (position) {
case 0:
args.putString("key", mMenuTitles[position]);
break;
case 1:
args.putString("key", mMenuTitles[position]);
break;
case 2:
args.putString("key", mMenuTitles[position]);
break;
case 3:
args.putString("key", mMenuTitles[position]);
break;
default:
break;
}
fragment.setArguments(args); // FragmentActivity将点击的菜单列表标题传递给Fragment
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.content_frame, fragment).commit();

    // 更新选择后的item和title，然后关闭菜单
    mMenuListView.setItemChecked(position, true);
    setTitle(mMenuTitles[position]);
    mDrawerLayout.closeDrawer(mMenuListView);
}

想要对应不同的fragment该怎么对应

Answer 1

replace的使用使用这个
.replace(R.id.content_frame, fragment ,yourTag).commit();

 Fragment fragment = getSupportFragmentManager().findFragmentByTag(yourTAg）
 if（fragment ！= null）{
  // do something
 }
