I am working in Fragment in which I need to select an image from gallery and set it to an imageView but getActivity().startActivityForResult() is now working

I have already checked many Links but all are saying that call this method in parent activity but I dont have any parent activity as this fragment is inside a another fragment. I have checked this link too

startActivityForResult is not working in Fragment

这是我的代码:-

MainActivity Class:-

public class SabaKuchHomeActivity extends FragmentActivity {

private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;

// nav drawer title
private CharSequence mDrawerTitle;

// used to store app title

    // nav drawer icons from resources
    navMenuIcons = getResources()
            .obtainTypedArray(R.array.nav_drawer_icons);

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.list_slidermenu);

    // adding nav drawer items to array
            // Home
            navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));

请让我知道我在这里犯了什么错误？？？

更新

我确实更新了 SabaKuchHomeActivity 和 ProfileSettingFragment

最佳答案

问题是您正在 Fragment 中实现 onActivityResult 并调用 getActivity().startActivityForResult(...)。因为您是从 Activity 启动 Activity，所以 onActivityResult(...) 方法调用转到启动新 Activity 的 Activity。

所以您需要做的就是删除 getActivity() 部分，您的 onActivityResult(...) 将在您的 Fragment 中被调用!

编辑: 从GrepCode可以看出，Fragment中的代码的 startActivityForResult 不同于 Activity的 startActivityForResult。这肯定不是巧合....

关于android - getActivity().startActivityForResult() 在 fragment 中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31717349/
