在我的片段，我想在我的列表視圖看，因爲每個自定義項目如下：動態添加元素的RelativeLayout
名稱
SetsXReps
[] [] [] [] [ ] ---> textviews
的陣列[] [] [] [] [] --->複選框
textviews和複選框的數量取決於在適配器中的項，因此，我的陣列需要動態創建該部分。我無法動態地將這些元素添加到我在xml中部分定義的relativelayout中。這是我的片段類，然後是我的xml自定義列表項。佈局的標識是list_item_exercise_in_workout。
public class WorkoutFragment extends Fragment public static final String EXTRA_ALREADYCREATED_ID =「shake2lift.nickdelnano.com」;
private ExAdapter adapter;
private ListView listView;
private ArrayList<Set> sets;
private Workout w;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
UUID workoutId = (UUID) getArguments().getSerializable(EXTRA_ALREADYCREATED_ID);
w = WorkoutMASTER.get(getActivity()).getWorkout(workoutId);
}
public View onCreateView(LayoutInflater inflater, ViewGroup parent,Bundle savedInstanceState)
{
View v = inflater.inflate(R.layout.fragment_workout, parent, false);
adapter = new ExAdapter(getActivity(), R.layout.fragment_create_workout, R.id.list, sets);
listView.setAdapter(adapter);
return v;
}
public static WorkoutFragment newInstance(UUID workoutId)
{
Bundle args = new Bundle();
args.putSerializable(EXTRA_ALREADYCREATED_ID, workoutId);
WorkoutFragment fragment = new WorkoutFragment();
fragment.setArguments(args);
return fragment;
}
private class ExAdapter extends ArrayAdapter<Set>
{
public ExAdapter(Context c, int resource, int textViewResourceId, ArrayList<Set> sets) {
super(c, 0, sets);
}
public View getView(final int position, View convertView, ViewGroup parent)
{
//if we werent given a view, inflate one
if(convertView == null)
{
convertView = getActivity().getLayoutInflater().inflate(R.layout.list_item_exercise_in_workout, null);
}
Set s = getItem(position);
//RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
// RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
TextView name = (TextView) convertView.findViewById(R.id.exName);
name.setText(s.getName());
TextView setsReps = (TextView) convertView.findViewById(R.id.setsXreps);
setsReps.setText(s.getSets() + "X" + s.getReps());
CheckBox[] checkBoxes = new CheckBox[s.getSetsInt()];
EditText[] weightBoxes = new EditText[s.getSetsInt()];
//initialize weightBoxes's text to the inputted weight
for(int i = 0; i < weightBoxes.length; i++)
{
//code to add dynamically here
}
return convertView;
}
}
}
和我的XML：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/relativeLayoutEx"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Name"
android:id="@+id/exName"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="SetsXReps"
android:id="@+id/setsXreps"
android:layout_below="@id/exName"
android:layout_alignParentLeft="true"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="@+id/button2"
android:layout_below="@+id/setsXreps"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="112dp" />
我明白任何幫助或建議。
