找不到用于ShooksFragment的ID的视图 [英] No view found for id for ShooksFragment

问题描述

我对所有这些片段内容都是陌生的，并且遇到了一个无法由StackOverflow的任何问题解决的错误.

I'm new to all this fragments stuff, and I get an error that couldn't be solved by any of the StackOverflow's questions.

我的问题是我得到

找不到片段ShooksFragment {1a77ec43#0 id = 0x7f0c0078的ID 0x7f0c0078(com.shook.android.shook:id/shooksLayout)的视图

No view found for id 0x7f0c0078 (com.shook.android.shook:id/shooksLayout) for fragment ShooksFragment{1a77ec43 #0 id=0x7f0c0078

尝试动态添加片段时.

我的代码:

MainActivity

MainActivity

...
@Override
public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();

    if (id == R.id.nav_friends) {
        Toast.makeText(getApplicationContext(), "Find friends!", Toast.LENGTH_LONG).show();

    } else if (id == R.id.nav_shooks) {

        FragmentManager fragmentManager = getFragmentManager();

        FragmentTransaction transaction = fragmentManager.beginTransaction();

        ShooksFragment fragment = new ShooksFragment();
        transaction.add(R.id.shooksLayout, fragment);

        transaction.commit();

    } else if (id == R.id.nav_prizes) {
        Toast.makeText(getApplicationContext(), "Get prizes!", Toast.LENGTH_LONG).show();
    } else if (id == R.id.nav_share) {
        Toast.makeText(getApplicationContext(), "Share your shooks!", Toast.LENGTH_LONG).show();
    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}
...

ShooksFragment

ShooksFragment

public class ShooksFragment extends Fragment {

public ShooksFragment() {
    // Required empty public constructor
}




@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_shooks, container, false);
}

// TODO: Rename and change types and number of parameters
public static ShooksFragment newInstance() {

    ShooksFragment fragment = new ShooksFragment();

    return fragment;
}

}

fragment_shooks.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

推荐答案

此行:

transaction.add(R.id.shooksLayout, fragment);

不正确，因为在片段的布局中定义了 R.id.shooksLayout .您在 add()中指定的 id 应该是您在中指定的 ViewGroup 的 id setContentView()进行活动.例如，对于片段，我通常在活动中保留一个空的< FrameLayout> ，然后在两个片段 add()<中都提供此容器的 id /code>和 replace()调用.

is incorrect because R.id.shooksLayout is defined in the layout of your fragment. The id you specify in add() should be the id of a ViewGroup you specify in your setContentView() fot the activity. For example, for my fragments I usually keep an empty <FrameLayout> in my activity and then provide the id of this container in both fragment add() and replace() calls.
