why first element of listView calling multiple times?

I am working on Calendar App to display list of items selected by user. i have set adapter in fragment with 2 array_lists(one for image resources and other for items name) and size of list but rather than to display particular number of list items only first item is coming and get_View method is calling 10 times just for first list element and only one item comes to display.

I am unable to comment due to low reputation. Kindly post the layout files. Also, instead of using two arraylists and a count variable, create a model class. It will make your code clean and easy to manage.

How to implement onItemClickListener with a custom array adapter?

I have been searching about this issue but still I am not very clear on how to use a click listener with an array adapter.
I need a click listener for each item of the list.
Codes:
The Area item:
package fogames.tamagomonsters;
public class Area {
public String name;
public String number;
public Area(String name, String number) {
this.name = name;
this.number = number;
}
}
The array adapter:
package fogames.tamagomonsters;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
public class AreasAdapter extends ArrayAdapter<Area> {
public AreasAdapter(Context context, ArrayList<Area> Areas) {
super(context, 0, Areas);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Area Area = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.item_area, parent, false);
}
// Lookup view for data population
TextView tvname = (TextView) convertView.findViewById(R.id.tvName_area);
TextView tvnumber = (TextView) convertView.findViewById(R.id.tvNumber_of_beasts);
// Populate the data into the template view using the data object
tvname.setText(Area.name);
tvnumber.setText(Area.number);
// Return the completed view to render on screen
return convertView;
}
}
The activity:
package fogames.tamagomonsters;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.Color;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.FrameLayout;
import android.widget.ListView;
import java.util.ArrayList;
public class PlayMenuActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
FrameLayout fl = new FrameLayout(this);
fl.setBackgroundColor(Color.argb(255, 0, 0, 0));
// Construct the data source
ArrayList<Area> arrayOfAreas = new ArrayList<Area>();
// Create the adapter to convert the array to views
AreasAdapter adapter = new AreasAdapter(this, arrayOfAreas);
// Attach the adapter to a ListView
ListView lv = new ListView(this);
lv.setAdapter(adapter);
// Restore preferences
SharedPreferences prefs = getSharedPreferences(PreferenceConstants.PREFERENCE_NAME, MODE_PRIVATE);
int mlen = prefs.getInt(PreferenceConstants.MLEN, 0);
long money = prefs.getLong(PreferenceConstants.MONEY, 0);
int mall = 6; //hay que ver que hacer con esto...
int eqall = 3; //igual
boolean[] mgot = new boolean[mall];
int[] exp = new int[eqall];
int[] lvl = new int[eqall];
int[] at = new int[eqall];
int[] en = new int[eqall];
for (int i = 0; i < mall; i++) {
mgot[i] = prefs.getBoolean(PreferenceConstants.MGOT[i], false);
}
for (int i = 0; i < eqall; i++) {
exp[i] = prefs.getInt(PreferenceConstants.EXP[i], 0);
lvl[i] = prefs.getInt(PreferenceConstants.LVL[i], 0);
at[i] = prefs.getInt(PreferenceConstants.AT[i], 0);
en[i] = prefs.getInt(PreferenceConstants.EN[i], 0);
}
String name[] = {getString(R.string.a001)};
int prado_got = 0;
if (mgot[0]) {
prado_got += 1;
}
if (mgot[3]) {
prado_got += 1;
}
String prado = String.valueOf(prado_got) + " / 2";
String number[] = {prado};
// Add item to adapter
Area a001 = new Area(name[0], number[0]);
adapter.add(a001);
this.setContentView(fl);
}
}
Thank you in advance.

You can do something like that:
•First insert in your adapter this method
#Override
public Area getItem(int position) {
return [yourArrayAreas].get(position);
}
•Then, in your Activity...
final AreasAdapter adapter = new AreasAdapter(this, arrayOfAreas);
ListView lv = new ListView(this);
lv.setAdapter(adapter);
mListStopsMuni.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id{
Area yourClickArea = adapter.getItem(position);
//Rest of code...
}
});
Good luck ;)

Something like this:
ArrayList<Area> arrayListAreas;
public AreasAdapter(Context context, ArrayList<Area> Areas) {
super(context, 0, Areas);
this.arrayListAreas = Areas;
}
//And then....
#Override
public Area getItem(int position) {
return arrayListAreas.get(position);
}

save view state with cursor adapter

Listview won't update from realm

After I create or receive a message send the message then save it to realm. Afterwards I need to update my threads ListView on the threads page and bring the newest messages to the top. I already have it so the thread list shows the updated preview and updated date, but it stays in it's inital ListView position. I tried to requery realm to get all info and reorder by the lastUpdated time, but it doesn't seem to work. Do I need to wipe the old thread list then repopulate it to get it to update?
I have the update triggered on the onResume()
#Override
protected void onResume() {
super.onResume();
updateListview = true;
updateList();
}
Here's my update
#UiThread
public void updateList() {
try {
if (updateListview) {
thread_realm = Realm.getInstance(this);
results = thread_realm.where(ZipListModel.class).findAllSorted("zipupdated", RealmResults.SORT_ORDER_DESCENDING);
adapter = new ZipListAdapter(this, results);
threadsListView.setAdapter(adapter);
adapter.notifyDataSetChanged();
if (results.size()==0){
createZipHint.setVisibility(View.VISIBLE);
} else {
createZipHint.setVisibility(View.INVISIBLE);
}
}
} catch (Exception e) {
e.printStackTrace();

The question is not quite clear to me but i can suggest some common ways to do this.
Assume your ZipListModel defined like this:
public class ZipListModel extends RealmObject {
private String title;
private Date date;
private String Author;
... getters and setters...
}
The easiest way to show your models in the ListView is using RealmBaseAdapter. You can find document here. And example.
eg.:
public class ZipListAdapter extends RealmBaseAdapter<ZipListModel> implements ListAdapter {
public ZipListAdapter(Context context, int resId,
RealmResults<ZipListModel> realmResults,
boolean automaticUpdate) {
super(context, realmResults, automaticUpdate);
}
...
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Update your views with the realmResults
...
ZipListModel zlm = realmResults.get(position);
authorTextView.setText(zlm.getAuthor);
...
}
...
}
The benifit of using RealmBaseAdapter is the realmResults can be updated automatically when the Realm transaction commited which means in your case, whenever you update your Realm by
thread_realm = Realm.getInstance(this);
thread_realm.beginTransaction()
// Change something in your Realm
...
thread_realm.commitTransaction()
The ZipListAdapter's notifyDataSetChanged will be called automatically and the listView will be updated.
BTW, you can still stay with your own adpater and simply update it by using RealmChangeListener. See example .

Try use RealmBaseAdapter.UpdateData(RealmResult<T> result). My project has similar requirement and it works for me

i have resolve this, the reason is : you had open the hardwareAccelerated attribute , you must close it in your manifest.xml like this
android:hardwareAccelerated = "false"
......
>
This problem is caused by more than 6.0 of Android's system automatically open the default hardware acceleration, but sometime we had no need to used it, Because most of the hardware capacity is still insufficient.
hope can help you!

#high sea company `s answer is right.
Thank you!!!
You can try like this:
in AndroidManifest.xml application:
<application android:hardwareAccelerated="false" ...>
in Activity :
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);
In layout XML :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:paddingLeft="2dp"
android:layerType="software" //**close hardwareAccelerated**
android:paddingRight="2dp" >
in View:
myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
