두 개의 마스터 디테일 프래그먼트가있는 주 활동이 있습니다. "Multiple fragments, multiple activities" 메서드를 구현하려고합니다.클래스 조각 오류가 부 풀릴 때 오류가 발생했습니다.
레이아웃 폴더 activity_main.xml
<FrameLayout 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"
tools:context=".MoneyActivity"
android:id="@+id/fragment_container" >
<fragment class="com.mysite.money.AFragment"
android:id="@+id/AFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</FrameLayout>
레이아웃 큰 폴더 activity_main.xml 태블릿에
<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"
tools:context=".MoneyActivity"
android:id="@+id/fragment_container"
android:orientation="horizontal" >
<fragment class="com.mysite.money.AFragment"
android:id="@+id/AFragment"
android:layout_width="@dimen/action_bar_title_text_size"
android:layout_height="match_parent"/>
<fragment class="com.mysite.money.BFragment"
android:id="@+id/BFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
나는 아래 (같은 오류가 발생했습니다를 실행 -layout-large) :
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mysite.money/com.mysite.money.MoneyActivity}: android.view.InflateException: Binary XML file line #15: Error inflating class fragment
조각의 클래스 이름을 올바르게 검사했습니다.
나는 내가 오류 것 같아 BFragment
BFragment : 공용 클래스 BFragment은 (단편 A를 관련)
내 mainActivity에 OnItemSelected SherlockFragment {
String selectedItem="";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
int size = getArguments().size();
if(size>0)
{
selectedItem = getArguments().getString("position").toString();
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
TextView textView=new TextView(inflater.getContext());
textView.setText("Selected Item->"+selectedItem);
return textView;
}
}를 확장
**@Override
public void onItemSelected(String id) {
BFragment displayFrag = (BFragment) getSupportFragmentManager().findFragmentById(new BFragment().getId());
if (displayFrag == null) {
// DisplayFragment (Fragment B) is not in the layout (handset layout),
// so start DisplayActivity (Activity B)
// and pass it the info about the selected item
Intent intent = new Intent(this, BActivity.class);
intent.putExtra("position", id);
Log.i("innodea", "position->"+id);
startActivity(intent);
} else {
// DisplayFragment (Fragment B) is in the layout (tablet layout),
// so tell the fragment to update
//displayFrag.updateContent(id);
}
}**
AFragment :
public class AFragment extends SherlockListFragment {
private View inflate;
private Callbacks mCallbacks = sDummyCallbacks;
private int mActivatedPosition= ListView.INVALID_POSITION;
private static final String STATE_ACTIVATED_POSITION = "activated_position";
public interface Callbacks {
public void onItemSelected(String id);
}
/**
* A dummy implementation of the {@link Callbacks} interface that does
* nothing. Used only when this fragment is not attached to an activity.
*/
private static Callbacks sDummyCallbacks = new Callbacks() {
public void onItemSelected(String id) {
}
};
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
// Activities containing this fragment must implement its callbacks.
if (!(activity instanceof Callbacks)) {
throw new IllegalStateException(
"Activity must implement fragment's callbacks.");
}
mCallbacks = (Callbacks) activity;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<DummyContent.DummyItem>(getActivity(),android.R.layout.simple_list_item_activated_1,android.R.id.text1, DummyContent.ITEMS));
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
// Restore the previously serialized activated item position.
if (savedInstanceState != null
&& savedInstanceState.containsKey(STATE_ACTIVATED_POSITION)) {
setActivatedPosition(savedInstanceState
.getInt(STATE_ACTIVATED_POSITION));
}
}
@Override
public void onDetach() {
super.onDetach();
// Reset the active callbacks interface to the dummy implementation.
mCallbacks = sDummyCallbacks;
}
@Override
public void onListItemClick(ListView listView, View view, int position,long id) {
super.onListItemClick(listView, view, position, id);
// Notify the active callbacks interface (the activity, if the
// fragment is attached to one) that an item has been selected.
mCallbacks.onItemSelected(DummyContent.ITEMS.get(position).id);
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
if (mActivatedPosition != ListView.INVALID_POSITION) {
// Serialize and persist the activated item position.
outState.putInt(STATE_ACTIVATED_POSITION, mActivatedPosition);
}
}
/**
* Turns on activate-on-click mode. When this mode is on, list items will be
* given the 'activated' state when touched.
*/
public void setActivateOnItemClick(boolean activateOnItemClick) {
// When setting CHOICE_MODE_SINGLE, ListView will automatically
// give items the 'activated' state when touched.
getListView().setChoiceMode(
activateOnItemClick ? ListView.CHOICE_MODE_SINGLE
: ListView.CHOICE_MODE_NONE);
}
private void setActivatedPosition(int position) {
if (position == ListView.INVALID_POSITION) {
getListView().setItemChecked(mActivatedPosition, false);
} else {
getListView().setItemChecked(position, true);
}
mActivatedPosition = position;
}
}
