Tôi chỉ cố gắng để có một cái nhìn vào Fragment và tôi đã nhận một số probs với thứ ngu ngốc ... Có SkippersActivity.java tôi:Không thể được đúc để android.app.Fragment
public class SkippersActivity extends Activity{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.skippers_fragment);
}
}
Và skippers_fragment.xml tôi:
<?xml version="1.0" encoding="utf-8"?>
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.arkezis.globedroid.SkippersFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/skippers_fragment">
</fragment>
Và có SkippersFragment.xml tôi:
public class SkippersFragment extends Fragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View mainView = inflater.inflate(R.layout.skippers, container, false);
return mainView;
}
}
skippers.xml của tôi:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView android:id="@+id/list_skippers_all"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
</LinearLayout>
Tại sao tôi nhận:

Bạn có thể dán câu lệnh nhập của SkippersFragment.java không? – Rajesh
nhập android.os.Bundle; nhập android.support.v4.app.Fragment; nhập android.view.LayoutInflater; nhập android.view.View; nhập android.view.ViewGroup; – Arkezis
