Listview adapter not displaying list columns after closing of Dialog

Setup
In my app I have a section that creates rows of data to be saved in a database. Each row is built from a textbox, number box then "set" into a listview for display. Later on the user can open a "plan" created before and review the data.
I created a listview, a custom layout for the display line and figured out how to add/display each new row. However, when I perform the open, I create a dialog to display the list for plans, user selects on and the rows should display. They do not. I trace through the code and I see the arraylist for the adapter being populated and I call the notifydatasetchanged, but the main listview remains empty.
I am not using a customer adapter class, but just the Simple adapter.
This is the beginning of the Activity. I am still learning android coding so I tend to use generic names as I learn.
public class TrackItEqMainActivity extends AppCompatActivity {
/**

* See https://g.co/AppIndexing/AndroidStudio for more information.
*/
private GoogleApiClient client;
public int rowCount = 1;
private static final String eTAG = "Exception";
final Context context = this;
// global variables needed for processing the add gaits display
**private ListView lstGaits;
private ListAdapter adapter;
private ArrayList<HashMap<String, String>> mylist;**
// *****
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(eTAG, "onCreate Build");
setTitle(R.string.activityManagePlans);
setContentView(R.layout.activity_track_it_eq_build);
Toolbar mySecondaryToolbar = (Toolbar) findViewById(R.id.my_secondaryToolbar);
setSupportActionBar(mySecondaryToolbar);
setActivityBuildListeners();
// set the objects needed to handle the dynamic gaits list
ListView lstGaits = (ListView) findViewById(R.id.lstMyGaits);
mylist = new ArrayList<HashMap<String, String>>();
try {
adapter = new SimpleAdapter(this, mylist, R.layout.gaits_detail,
new String[] { "keyGait", "keyTime" }, new int[] {
R.id.txtdisplayGait, R.id.txtdisplayTime });
lstGaits.setAdapter(adapter);
} catch (Exception e) {
Log.i(eTAG, e.getMessage());
}
// ATTENTION: This was auto-generated to implement the App Indexing API.
// See https://g.co/AppIndexing/AndroidStudio for more information.
client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
}
SO when a user taps a new button a set of controls appear allowing to select a gait and enter a time. They then tap on the set button and in the set onClick, I add the data to the internal array and display the custom layout on the screen.
private Button.OnClickListener onClick_btnSet = new OnClickListener() {
#Override
public void onClick(View v) {
Spinner spinner = (Spinner) findViewById(R.id.spinner_gaits);
TextView textGait = (TextView) spinner.getSelectedView();
String gtResult = textGait.getText().toString();
TextView txtTime = (TextView) findViewById(R.id.txtSelected);
String tmeResult = txtTime.getText().toString();
buildDisplayLine(true,gtResult,tmeResult);
txtTime.setText("");
spinner.requestFocus();
}
};
The function that builds the line and adds to the array is this:
private void buildDisplayLine(boolean isNew, String gait, String time) {
HashMap<String, String> map2 = new HashMap<String, String>();
map2.put("keyGait",gait); // put the col data in
map2.put("keyTime", time); // put the col data in
mylist.add(map2);
if (isNew) {
((BaseAdapter) (adapter)).notifyDataSetChanged();
}
}
All that works although a strange side effect is that the list will not display if the number keypad is visible. When I clear it off the list appears.
Ifa use wants to look at or change a plan they tap the open button. IT display a dialog box that shows a list of plans. Tap on a plan and all the elements should display:
private final ThreadLocal<OnClickListener> onClick_btnOpen = new ThreadLocal<OnClickListener>() {
#Override
protected OnClickListener initialValue() {
return new OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.activity_track_it_eq_open_plan);
dialog.setTitle("Open Exercise Plan...");
Button diaCancelButton = (Button) dialog.findViewById(R.id.btnCancelOpen);
diaCancelButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
// get a list of files from the local app plans
final eqDatabaseService eqDB = new eqDatabaseService(context, 2);
ArrayList<HashMap<String,String>> allPlans = eqDB.getPlanList();
if (allPlans.isEmpty()) {
Toast toast = new Toast(context);
toast.setGravity(Gravity.TOP, 0, 0);
Toast.makeText(context, "No Files to open, Please create one!", Toast.LENGTH_LONG).show();
return;
}
ListView lvPlan = (ListView) dialog.findViewById(R.id.lvPlans);
try {
adapter = new SimpleAdapter(context, allPlans, R.layout.plans_columns,
new String[] { "keyName", "keyENum" }, new int[] {
R.id.txtPlanName, R.id.txtNumElements });
lvPlan.setAdapter(adapter);
} catch (Exception e) {
}
//********************************************************
lvPlan.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
TextView txtplan = (TextView) v.findViewById(R.id.txtPlanName);
String planName = txtplan.getText().toString();
List<eqSessions_dt> myPlan = eqDB.getCurrentPlan(planName);
clearGrid();
for (eqSessions_dt row : myPlan) {
buildDisplayLine(false, row.get_gait(),Integer.toString(row.get_time()));
}
((BaseAdapter)(adapter)).notifyDataSetChanged();
dialog.dismiss();
}
});
dialog.show();
}
};
}
};
I have played around with this, did look at other similar questions and answers, but didn't see anything that would explain why the notify would not work. I avoided doing a custom adapter, trying to keep this simple at first. What am I missing that stops the list from displaying. I see the arraylist being filled and all related objects are global to the activity. I'll keep playing around, but I hope otehr eyes see what I miss.

My database show nothing in my listview

In my project I have database and I want to fill data from database into my listview. But It shows nothing without any errors.
I open the database easily and get data from it and set to my arraylist and finally I put in into my listview.
where is the problem?
I am new with android
here is my code:
public class MainActivity extends Activity {
private ListView listView;
public static SqliteHelper database;
private ArrayList<ItemJomle> arrayDatas;
private ArrayAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
arrayDatas = new ArrayList<>();
database = new SqliteHelper(this);
try {
database.createDataBase();
} catch (IOException e) {
e.printStackTrace();
}
listView = (ListView)findViewById(R.id.lstcontent);
updateListViewData();
}
public void updateListViewData() {
database.open();
arrayDatas = database.getDataListView();
adapter = new AdapterData(arrayDatas);
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
database.close();
}
public static void updateFav(int id,String value){
database.open();
database.updateDatabase(id,value);
database.close();
}
}
And here is my code:
public ArrayList<ItemJomle> getDataListView() {
String selectQuery = "SELECT * FROM " + TBL_NAME ;
arrayListViwedatas.clear();
Cursor cu = Mydb.rawQuery(selectQuery, null);
if(cu!=null){
cu.moveToFirst();
if(cu.moveToFirst()){
while (cu.isAfterLast() == false) {
ItemJomle item = new ItemJomle();
item.id = cu.getInt(cu.getColumnIndex("id"));
item.subject = cu.getString(cu.getColumnIndex("subject"));
item.text = cu.getString(cu.getColumnIndex("text"));
item.nubmer = cu.getString(cu.getColumnIndex("number"));
item.fav = cu.getString(cu.getColumnIndex("fav"));
arrayListViwedatas.add(item);
cu.moveToNext();
}
cu.close();
}
}
return arrayListViwedatas;
}
and my layout:
<LinearLayout

android:layout_height="match_parent"
android:layout_weight="1">

My listview in import_fragment.xml, when i open import_fragment.xml in app its appear only Contact Name and Phone and Email and Address which is added in import_fragment.xml and not the new contact information which in database added by user.

You have to setAdapter in onCreateView. Currently you are populating the list in onCreateContextMenu. Moreover, after setting the adapter, you have to call notifyDataSetChanged() as well

Try this way, i have tried this in my machine and it show me listview properly , i have done with weightSum so it will be applicable for all devices , just change your xml file with below one
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="4">
<ImageView
android:id="#+id/ivContactImage"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
android:orientation="vertical">
<TextView
android:id="#+id/contactName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="Contact Name"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/phoneNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:layout_marginTop="5dp"
android:text="Phone" />
<TextView
android:id="#+id/emailAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="Email" />
<TextView
android:id="#+id/cAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="Address" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="My Contacts"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
</LinearLayout>
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center" />

Change both of your LinearLayout's height to
android:layout_height="fill_parent"
Your listView is actually "there", it's just that the container (layout) of the listView isn't big enough to fit it.
EDIT:
You are defining two different list of Contacts there! Both activity and adapter class are referring to two different Contacts. Remove the one inside the onCreateView function.
final List<import_fragment.Contact> Contacts = new ArrayList<import_fragment.Contact>();

Getting text from custom ListView

As the title says really.. I have a list view with 3 text view's in it, see below.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="20dp" >
<TextView
android:id="#+id/text1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="#000"
android:textSize="20dp"
android:textStyle="bold" />
<TextView
android:id="#+id/text2"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textSize="12sp"
android:textStyle="bold" />
<TextView
android:id="#+id/text3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp"
android:textStyle="italic"
android:typeface="sans" />
</LinearLayout>
This is how I call it.
public void displayResultList(ArrayList<HashMap<String, String>> results2) {
// TODO Auto-generated method stub
lv = (ListView) findViewById(android.R.id.list);
SimpleAdapter adapter = new SimpleAdapter(this, results2,
R.layout.custom_row_view,
new String[] { "Ear", "Breed", "Sex" }, new int[] { R.id.text1,
R.id.text2, R.id.text3 });
lv.setAdapter(adapter);
}
and this is how I try to retrieve the text, but this doesn't work..
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
String item = (String) ((TextView) v).getText();
Toast toast3 = Toast.makeText(this, "items = " + item,
Toast.LENGTH_SHORT);
toast3.show();
// Intent mainIntent3 = new Intent(this,CowDetailsActivity.class);
// mainIntent3.putExtra("cow", item.substring(10, 16));
// startActivity(mainIntent3);
}
Can anybody tell me how I can get the first line of text?
Thanks in advance

Can anybody tell me how I can get the first line of text?
((HashMap<String, String>)l.getItemAtPosition(position) will give you your HashMap. I don't know what "the first line of text" is.
Or, if you still have results2 held somewhere, results2.get(position) will also return to you your HashMap.

android listview is iterating through the footer menus too

This is my activity code:
#Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
String[] names = new String[] { "Investor Relations", "Social Sharing", "Rate this app", "About Rathbones",
"Disclaimer", "Security", "Credits"};
// Create an ArrayAdapter, that will actually make the Strings above
// appear in the ListView
this.setListAdapter(new ArrayAdapter<String>(this, R.layout.moremenulist,
R.id.label, names));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
// Get the item that was clicked
Object o = this.getListAdapter().getItem(position);
String keyword = o.toString();
Toast.makeText(this, "You selected: " + keyword, Toast.LENGTH_LONG).show();
}
And here is the xml file for this:

Now, when the activity is loading it is appending the menu with each item in the list. I just want it to appear only in bottom not with each and every list item.
any suggestions?
Edit-1 :
I tried this but getting an error of nullpointer exception
View footerView =
((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer, null, false);
ListView lv = new ListView(this);
lv.addFooterView(footerView);

What do you mean by menu? Do you mean your ImageButtons?
If that's the case then remove those create another layout for those ImageButtons and add them using ListView.addFooterView() instead.
You could create e.g. list_footer_layout.xml, which contains your ImageButtons. Then:
public void onCreate(Bundle bundle) {
...
ListView lv = getListView(); // If your activity is ListActivity
View foot = getLayoutInflater().inflate(R.layout.list_footer_layout, null);
lv.addFooterView(foot);
}
