이벤트 처리에서 작은 문제가 있으며, 나는 사용자 정의 어댑터 데이터, 날짜, 제목, 가격을 갖는 각 행을 볼 수 있습니다.행을 클릭하면 세부 정보 페이지를 표시해야하지만 가격, 날짜 또는 제목을 길게 누르면 목록보기를 정렬해야합니다.긴 언론에서 제스처를 사용해야합니다.아래의 코드를 참조하십시오.
사용자 정의 어댑터보기
public EventAdapterView(Context context, List<EventUtil> eventList) {
this.mContext = context;
this.mEventUtil = eventList;
mLayoutInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageLoader = new DrawableManager();
}
@SuppressLint("DefaultLocale")
@SuppressWarnings("deprecation")
@Override
public View getView(int position, View convertView, ViewGroup parent) {
mView = convertView;
EventUtil eventUtil = mEventUtil.get(position);
mView = mLayoutInflater.inflate(R.layout.row_event_adapter, null);
TextView eventTitleView = (TextView) mView
.findViewById(R.id.list_view_event_title);
TextView eventDescView = (TextView) mView
.findViewById(R.id.list_view_event_location);
TextView eventDateView = (TextView) mView
.findViewById(R.id.list_view_event_price);
// final MyGestureDetector myGestureDetector= new MyGestureDetector();
// new ImageFeach().execute(mEventUtil.getEvent_Image_Url());
eventTitleView.setText(eventUtil.getEvent_Title());
// event title sorting
eventTitleView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
new MyGestureDetector() {
public void onLongPress(MotionEvent event1) {
//if (event1.getAction() == MotionEvent.ACTION_DOWN) {
Collections.sort(mEventUtil,
new Comparator<EventUtil>() {
@Override
public int compare(EventUtil obje1,
EventUtil obje2) {
return obje1
.getEvent_Title()
.compareTo(
obje2.getEvent_Title());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
// event location sorting
eventDescView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
new MyGestureDetector() {
public void onLongPress(MotionEvent event1) {
//if (event1.getAction() == MotionEvent.ACTION_DOWN) {
Collections.sort(mEventUtil,
new Comparator<EventUtil>() {
@Override
public int compare(EventUtil event1,
EventUtil event2) {
return event1
.getEvent_location()
.compareTo(
event2.getEvent_location());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
// event price sorting
eventDateView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
new MyGestureDetector() {
public void onLongPress(MotionEvent event1) {
// if (event1.getAction() == MotionEvent.ACTION_DOWN) {
Collections.sort(mEventUtil,
new Comparator<EventUtil>() {
@Override
public int compare(EventUtil event1,
EventUtil event2) {
return event1
.getEvent_Price()
.compareTo(
event2.getEvent_Price());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
// event date sorting
ImageView dateImageView = (ImageView) mView
.findViewById(R.id.list_view_event_date);
dateImageView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
new MyGestureDetector() {
public void onLongPress(MotionEvent event1) {
//if (event1.getAction() == MotionEvent.ACTION_DOWN) {
Collections.sort(mEventUtil,
new Comparator<EventUtil>() {
@Override
public int compare(EventUtil event1,
EventUtil event2) {
return event2
.getEvent_Date()
.compareTo(
event1.getEvent_Date());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
myGregTeDetector 클래스
public class MyGestureDetector extends SimpleOnGestureListener {
@Override
public void onLongPress(MotionEvent e) {
super.onLongPress(e);
}
}
도와주세요 .. 감사합니다
해결책
SimpleOnGestureListener를 사용할 필요가 없습니다.
사용자 정의 어댑터보기에서 :
첫째,
eventTitleView.setFocusable(false);
eventTitleView.setFocusableInTouchMode(false);
eventTitleView.setLongClickable(true);
eventDescView.setFocusable(false);
eventDescView.setFocusableInTouchMode(false);
eventDescView.setLongClickable(true);
eventDateView.setFocusable(false);
eventDateView.setFocusableInTouchMode(false);
eventDateView.setLongClickable(true);
다음,
setOnLongClickListener (View.OnLongClickListener l), eventTitleView 및 eventDescView로 eventDateView를 그냥 설정하십시오.
eventTitleView.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
//do your sorting stuff here
}
});
eventDescView.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
//do your sorting stuff here
}
});
eventDateView.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
//do your sorting stuff here
}
});
이것이 당신을 돕기를 바랍니다.
다른 팁
왜 켜짐을 무시해야합니까?
이 기능을 기본적으로 사용할 수 있습니다.
그냥 가격, 날짜 또는 제목을 같은 레이아웃에 넣고 각각의 onlongpresslistener를 원하는 액션으로 제공하십시오. :
예제 : .http://www.mikeplate.com/2010/01/21/show-a-context-menu-for-long-clicks-in-an-Android-listview/
이 Thro onLongClickListener를 수행했습니다.이 인터페이스를 사용하는 것은 쉽습니다.
Class YourClass implements onLongClickListener{
public boolean onLongClick(View arg0){
// Event generated when user have long pressed the screen
return false; // If you do not want the event to keep occuring again and again
}
ListView.setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// YOUR SORTING CODE HERE
return false;
}
});
