Question

我是所有这些碎片的新手，我得到的错误是任何StackOverflow的问题无法解决的。

我的问题是我收到错误

对于片段ShooksFragment {1a77ec43＃0 id = 0x7f0c0078
，找不到id 0x7f0c0078（com.shook.android.shook：id / shooksLayout）的视图

尝试以动态方式添加片段时。

我的代码：

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

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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.shook.android.shook.ShooksFragment"
android:id="@+id/shooksLayout">

Answer 1

这一行：

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

不正确，因为R.id.shooksLayout的布局中定义了fragment。您在id中指定的add()应该是您在活动id中指定的ViewGroup的{{1}}。例如，对于我的片段，我通常在我的活动中保留一个空的setContentView()，然后在片段<FrameLayout>和id调用中提供此容器的add()。

Answer 2

试试这个：

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

找不到用于ShooksFragment的id的视图
