我必须为姜饼版本实现多选对话框。
我的名为EventCreateActivity的主Activity扩展了名为BaseActivity的类,并扩展了SherlockActivity。
主要活动
public class EventCreateActivity extends BaseActivity implements OfferDialogFragment.OfferDialogListner{
在主活动中,我如下调用了dialog,但它在newFragment.show方法上给出了一个错误,该方法名为“方法getSupportFragmentManager()对于EventCreateActivity类型是未定义的”。OfferDialogFragment类具有扩展的dialogFragment类别。
DialogFragment newFragment = new OfferDialogFragment();
Bundle databndle = new Bundle();
boolean offerArr [] = vip.getBooleanOffers(include_offer.getText().toString());
databndle.putBooleanArray("BOOL_OFFERS_ARRAY", offerArr);
newFragment.setArguments(databndle);
newFragment.show(getSupportFragmentManager(), "OfferDialogFragment");
如果有人帮我解决这个问题,那就太麻烦了。提前谢谢!
编辑01:这是EventCreateActivity的完整代码
public class EventCreateActivity extends BaseActivity implements OfferDialogFragment.OfferDialogListner{
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
return new DatePickerDialog(this, datePickerListener,
year, month,day);
case OFFER_DIALOG_ID:
DialogFragment newFragment = new OfferDialogFragment();
Bundle databndle = new Bundle();
boolean offerArr [] = vip.getBooleanOffers(include_offer.getText().toString());
databndle.putBooleanArray("BOOL_OFFERS_ARRAY", offerArr);
newFragment.setArguments(databndle);
newFragment.show(getFragmentManager(), "OfferDialogFragment");
return onCreateDialog(id);
}
}
//OfferDialogFragment类
public class OfferDialogFragment extends SherlockDialogFragment{
public interface OfferDialogListner{
public void onDialogPositiveClick(DialogFragment dialog, ArrayList<Integer> selected);
public void onDialogNegativeClick(DialogFragment dialog);
}
OfferDialogListner mOfferDialogListner;
@Override
public void onAttach(android.app.Activity activity) {
super.onAttach(activity);
try{
mOfferDialogListner = (OfferDialogListner) activity;
}catch(ClassCastException e){
throw new ClassCastException(activity.toString() + " must implement OfferDialogListner");
}
};
@Override
public Dialog onCreateDialog(Bundle savedInstanceState){
final ArrayList<Integer> mSelectedOfferItems = new ArrayList<Integer>();
boolean [] selectOfferItems = getArguments().getBooleanArray("BOOL_OFFERS_ARRAY");
// add array data to arrayalist
if(selectOfferItems[0]){
mSelectedOfferItems.add(0);
}
if(selectOfferItems[1]){
mSelectedOfferItems.add(1);
}
if(selectOfferItems[2]){
mSelectedOfferItems.add(2);
}
if(selectOfferItems[3]){
mSelectedOfferItems.add(3);
}
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.artist_offer_tv)
.setMultiChoiceItems(R.array.offer_items, selectOfferItems, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
if(isChecked){
mSelectedOfferItems.add(which);
}else{
mSelectedOfferItems.remove(Integer.valueOf(which));
}
}
})
.setPositiveButton(R.string.string_ok , new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Integer[] selected = mSelectedOfferItems.toArray(new Integer[mSelectedOfferItems.size()]);
mOfferDialogListner.onDialogPositiveClick(OfferDialogFragment.this, mSelectedOfferItems);
}
})
.setNegativeButton(R.string.string_cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
mOfferDialogListner.onDialogNegativeClick(OfferDialogFragment.this);
}
});
return builder.create();
}
}
