How to disable previous items in a ListView

I am trying to develop an activity where there is a custom listView made out of CustomAdapter.
The list consists of a TextView and an EditText. The EditText when clicked, it auto fetches the system time.
What I want is when a particular EditText is filled, I want all the previous(above) list items in the sequence to be disabled.
So far, I have tried using isEnabled() and areAllItemsEnabled() functions returning respective boolean values using position, but however didn’t work.
Please help me achieve the above.
Thanks.
This is my CustomAdapter Class
public class SelectStnListByRoute extends BaseAdapter implements View.OnClickListener {
Context context;
ArrayList<StnNames> stnList;
LayoutInflater layoutInflater = null;
ViewHolder viewHolder;
private int mLastClicked;
public SelectStnListByRoute(Context context, ArrayList<StnNames> stnList) {
super();
this.context = context;
this.stnList = stnList;
layoutInflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return stnList.size();
}
#Override
public Object getItem(int position) {
return stnList.get(position);
}
#Override
public long getItemId(int position) {
return stnList.indexOf(getItem(position));
}
public int getViewTypeCount() {
return 1;
}
#Override
public boolean areAllItemsEnabled() {
return false;
}
#Override
public boolean isEnabled(int position) {
if(position==position){
return false;
}
return false;
}
#Override
public View getView(final int position, View convertView, ViewGroup viewGroup) {
int type = getItemViewType(position);
StnNames stnDetails = stnList.get(position);
viewHolder = new ViewHolder();
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.footplate_custome_layout, null);
viewHolder.txtStnNAme = (TextView) convertView.findViewById(R.id.txtStnCode);
viewHolder.txtStnArr = (TextView) convertView.findViewById(R.id.txtArrivalTime);
viewHolder.txtStnDep = (TextView) convertView.findViewById(R.id.txtDepTime);
convertView.setTag(viewHolder);
viewHolder.txtStnArr.setTag(stnDetails);
viewHolder.txtStnDep.setTag(stnDetails);
} else {
viewHolder = (ViewHolder) convertView.getTag();
viewHolder.txtStnArr.setTag(stnDetails);
viewHolder.txtStnDep.setTag(stnDetails);
}
viewHolder.txtStnNAme.setText(stnDetails.getStnCode());
viewHolder.txtStnArr.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.e("Position: " , String.valueOf(position)); //Here I am getting the position of the row item clicked, where should I put the Onclick false for disabling all of the above fields using the position?
}
});
viewHolder.txtStnDep.setOnClickListener(this);
viewHolder.txtStnArr = (TextView) convertView.findViewById(R.id.txtArrivalTime);
if (stnDetails.getArrivalTime() != null) {
viewHolder.txtStnArr.setText(stnDetails.getArrivalTime());
} else {
viewHolder.txtStnArr.setText("");
}
if (stnDetails.getDeptTime() != null) {
viewHolder.txtStnDep.setText(stnDetails.getDeptTime());
} else {
viewHolder.txtStnDep.setText("");
}
return convertView;
}
class ViewHolder {
TextView txtStnNAme, txtStnArr, txtStnDep;
int ref;
}
#Override
public void onClick(View view) {
int id = view.getId();
switch (id) {
case txtArrivalTime:
TextView textViewArrVal = (TextView) view.findViewById(R.id.txtArrivalTime);
textViewArrVal.setClickable(false);
StnNames listItemsArrr = (StnNames) textViewArrVal.getTag();
if (listItemsArrr.getArrivalTime() != getCurrentTime()) {
listItemsArrr.setArrivalTime(getCurrentTime());
if (listItemsArrr.getArrivalTime() != null) {
int position = textViewArrVal.getSelectionStart();
textViewArrVal.setText(listItemsArrr.getArrivalTime());
} else {
textViewArrVal.setText("");
}
}
break;
case txtDepTime:
TextView textViewDepVal = (TextView) view.findViewById(R.id.txtDepTime);
StnNames listItemsDepp = (StnNames) textViewDepVal.getTag();
if (listItemsDepp.getDeptTime() != getCurrentTime()) {
listItemsDepp.setDeptTime(getCurrentTime());
if (listItemsDepp.getDeptTime() != null) {
textViewDepVal.setText(listItemsDepp.getDeptTime());
} else {
textViewDepVal.setText("");
}
}
break;
default:
break;
}
}
public String getCurrentTime(){
Calendar calendar = Calendar.getInstance();
SimpleDateFormat mdformat = new SimpleDateFormat("HH:mm:ss");
String arrDate = mdformat.format(calendar.getTime());
return arrDate;
}
}

You can do this as below mentioned -:
You need to store the position of clicked button was. So initialize a variable in your class
int mButtonSelected = -1;
EDIT 1.
Then make a change to your isEnabled method
#Override
public boolean isEnabled(int position) {
if(position<mButtonSelected){
return false;
}
return true;
}
That will work it if any other button was clicked. but you have to do that in your onClick
mButtonSelected = position;
notifyDataSetChanged();
Let me it worked or not
EDIT
see below changes in your code-:
public class SelectStnListByRoute extends BaseAdapter {

Get the position of the row which is clicked and then set onclick false for positions less than clicked position
as follows:
viewHolder.txtStnArr.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.e("Position: " , String.valueOf(position));
for (int i = 0; i < position; i++) {
viewHolder.txtStnArr.setEnable(false);
}
notifyDataSetChanged();
}
});

I set view.setClickable (false)in my Adapter, but it does not work.

item.setEnabled(false);
when u need to make it clickable call
item.setEnabled(true);
Here item is your edittext or button or anything else
Try this:
if (room.getRoom_status().equals("0") &&room.getRoomType().getRoom_type_name().equals("0")) {
view.setBackgroundResource(R.drawable.single);
view.setEnabled(false);
} else if (room.getRoom_status().equals("1") && room.getRoomType().getRoom_type_name().equals("0")) {
view.setBackgroundResource(R.drawable.single_b);
} else if (room.getRoom_status().equals("1") && room.getRoomType().getRoom_type_name().equals("1")) {
view.setBackgroundResource(R.drawable.double_b);
} else if(room.getRoom_status().equals("0") && room.getRoomType().getRoom_type_name().equals("1")){
view.setEnabled(false);
view.setBackgroundResource(R.drawable.doubleg);
}
else
view.setEnabled(true);

The right way is to write a Boolean value, and let it based on a Boolean value to determine whether to jump.
private boolean checkedIntent = false;
if (roomstate.equals("0") && roomtype.equals("0")) {
checkedIntent = false;
} else if (roomstate.equals("1") && roomtype.equals("0")) {
checkedIntent = true;
} else if (roomstate.equals("1") && roomtype.equals("1")) {
checkedIntent = true;
} else if (roomstate.equals("0") && roomtype.equals("1")) {
checkedIntent = false;
}
if (checkedIntent == true) {
Intent intent = new Intent(RoomList.this, BookRoomDetail.class);
intent.putExtras(mBundle);
startActivity(intent);
}

Android:Receive Array of Objects and display in listView

Hello to all android folks over there!!
I want to get list of objects from web service and want to display them in list view.Now i am able to fetch those values and collected them in arraylist.But i am facing problem to display them in list view.below is my code.
Using everyones suggestion ,i solved my problem.Thats the spirit of android buddies.I am pasting my answer in UPDATED block.Hope it will be helpful in future.

you can try this:
this is the adapter class code.
public class CustomTaskHistory extends ArrayAdapter<String> {
private Activity context;
ArrayList<String> listTasks = new ArrayList<String>();
String fetchRefID;
StringBuilder responseOutput;
ProgressDialog progress;
String resultOutput;
public String getFetchRefID() {
return fetchRefID;
}
public void setFetchRefID(String fetchRefID) {
this.fetchRefID = fetchRefID;
}
public CustomTaskHistory(Activity context, ArrayList<String> listTasks) {
super(context, R.layout.content_main, listTasks);
this.context = context;
this.listTasks = listTasks;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_task_history, null, true);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
LinearLayout linearLayout = (LinearLayout) listViewItem.findViewById(R.id.firstLayout);
//System.out.println("client_id" + _clientID);
//TextView textViewDesc = (TextView) listViewItem.findViewById(R.id.textViewDesc);
//ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView);
if (position % 2 != 0) {
linearLayout.setBackgroundResource(R.color.sky_blue);
} else {
linearLayout.setBackgroundResource(R.color.white);
}
textViewName.setText(listTasks.get(position));
return listViewItem;
}
}
and now in the parent class you must have already added a list view in your xml file so now display code for it is below:
CustomTaskHistory customList = new CustomTaskHistory(TaskHistory.this, task_history_name);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(customList);
you can also perform any action on clicking cells of listview.If needed code for it is below add just below the above code:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent nextScreen2 = new Intent(getApplicationContext(), SubscribeProgrammes.class);
nextScreen2.putExtra("CLIENT_ID", _clientID);
nextScreen2.putExtra("REFERENCE_ID", reference_IDs.get(i));
startActivity(nextScreen2);
Toast.makeText(getApplicationContext(), "You Clicked " + task_list.get(i), Toast.LENGTH_SHORT).show();
}
});

AdapterView of Gridview is not refreshing, it is showing weird response (Some times it is refreshing some times not)

I am setting the adapter of gridview on a fragment. this fragment is attached on the layout of view pager and viewpager is attached in an activity.
I have checked my arraylist data is refreshed but view is not refreshing.
My code is:
Setting the adapter in the onCreate of Activity::
for(ArrayList<Item> newLst : updateList){
newPropertySubList.add(newLst);
}
Log.e("newPropertySubList","newPropertySubList"+newPropertySubList.size());
adapter = new PropertyPagerAdapetr(getSupportFragmentManager());
//propertyViewPager.setAdapter(adapter);
adapter.notifyChangeInPosition(1);
propertyViewPager.setAdapter(adapter);
adapter.notifyDataSetChanged();
mIndicator.setViewPager(propertyViewPager);
PropertyPagerAdapetr is: in this code section GridviewFragment new instance is created when adapter is setting.
public class PropertyPagerAdapetr extends FragmentPagerAdapter {
private long baseId = 0;
public PropertyPagerAdapetr(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int arg0) {
return GridViewFragment.newInstance(newPropertySubList.get(arg0));
}
#Override
public long getItemId(int position) {
return baseId + position;
}
public void destroyAllItem(){
getSupportFragmentManager().getFragments().clear();
}
#Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
#Override
public int getCount() {
if (newPropertySubList != null && newPropertySubList.size() > 0)
return newPropertySubList.size();
else
return 0;
}
public void notifyChangeInPosition(int n) {
// shift the ID returned by getItemId outside the range of all previous fragments
baseId += getCount() + n;
}
}

Could be you're mixing GridLayout and GridView. They are different entities.
In setUpGridLayout() you are inflating a grid_view_imageviewitem and adding it to a GridLayout, not GridView.
