PopUp Window not updating database - Android

PopUp Window not updating database - Android - android

I'm trying to create a kind of game using Android Studio. Till now I have done a gridview wich shows players stored in a database. I have had some problems with gridView.setOnItemClickListener, I have had to do it by putting the code into gridView's Adparter.class so if you know how I can do that into gridView's activity please tell me.
My problem now is that when you click on a player a popup window appears in which you could change the player's name or his genre. When you click on Confirm's button the database will automatically been updated, but it doesn't works. I have try to do it step by step by using Toast in order to know if it run that part or not, the problem could be the context, but maybe I'm crazy.
I left you some pics and the code related to it.

From what I´ve seen in your code is, that you try to get the id from an intent in your PopUp window class. You have made one thing wrong:
Intent i = getIntent();
i.getIntExtra("Id", id);
it must be:
Intent i = getIntent();
id = i.getIntExtra("Id", id); //forgott id = here
and you should give a default value to id for example id=-1 . The problem is, by updating your database, you give a non value integer and so it is not possible to update your table.

Menu is not displaying on activity_main.xml

The problem is it is not showing. Do I need something to trigger the onCreateOptionsMenu method?

In your onCheckedChanged() method save the positions in a list. and when button is clicked iterate through the list and delete them from the adapter list.

OnItemClickListener doesn't fire

The Register Button works well, but the debugger doesn't run into the setOnItemClickListener onItemClick. If You click on a item, the activity for editing the record should be launched.

I add the item clickable for the textfield. I think that is not realy necesarry.

You have focusable/clickable items in your list view item - the checkbox.
Option 1 - Set the android:descendantFocusability="blocksDescendants" flag to your ListView and you should have fired the onItemClickListener.
Option 2 - In your Adapter you can set an onClickListener on the entire list view item object, and handle it from there.

the Problem of my solution was on row.xml
again thanX on all:
row.xml
<LinearLayout
android:clickable="true" (removed)
<TextView
android:id="#+id/tv_title"
android:onClick="Title" (added)
android:clickable="true" (added)
android:focusable="true" (added)
on my Activity_cardmanager I inserted following code after nameList.setAdapter...
nameList.setClickable(true); // 2015-04-14
nameList.setFocusable(true); // 2015-04-14
nameList.setItemsCanFocus(true); // 2015-04-14
setViewItemListener();
.
.
.
public void setViewItemListener() {
nameList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> tobjParent, View tobjView, int tintPosition, long tlngid) {
Bundle passdata = new Bundle();
// Cursor listCursor = (Cursor) tobjParent.getItemAtPosition(tintPosition);
Cursor listCursor = (Cursor) nameList.getItemAtPosition(tintPosition); //2015-04-15
int nameId = listCursor.getInt(listCursor
.getColumnIndex(MindXopenHelper.KEY_ID));
passdata.putInt(MindXopenHelper.KEY_ID, nameId);
Intent passIntent = new Intent(Activity_cardmanager.this,
Activity_edit_mindxtables.class);
Toast.makeText(getApplicationContext(),
Integer.toString(nameId), Toast.LENGTH_LONG).show();
passIntent.putExtras(passdata);
startActivity(passIntent);
}
});
}
the returnValue is true, but that is another story.

Using getFragmentManager on a ListActivity

I just want to know if this is possible since first. I have created a custom listView based on the tutorial I read from Sai Geetha. Well it works perfectly on my app except that it needs to extend ListActivity instead of FragmentActivity. Now I'm having a hard time configuring and adding a dialog for this since I need to apply a fragment dialog and I can't use the getFragmentManager() since I'm not working with the FragmentActivity. Is there's another way I can do to work on this without sacrificing the ListActivity? Thanks!
Here's my code so far

You can use ListFragment inside FragmentActivity instead of using a ListActivity.

Change TextView when item is clicked on a ListAdapter?

I have two classes and a XML. The first one creates an ListApter full of cocktail names like bloody mary,margarita, ect. The second class is set up so I can change the TextView and an Image displayed in the XML. I'm having difficulty trying to pass the item that I'v pressed in the ListAdapter into the CocktailDetail class to change the values of the TextView and the Image. Can anybody help? It runs but opens Bloody mary for every item selected in the list.

In Menu class, you are passing hard coded string :
ourIntent.putExtra("cocktail_name",**"bloodymary"**);
Change this to the value retrieved from the ListView :
String selectedFromList =(String) (l.getItemAtPosition(position));
ourIntent.putExtra("cocktail_name",selectedFromList);
Also in Cocktail Class, OnCreate, again you are setting text to hardcoded string. Using Bundle, retrieve the value and then setText;
Bundle bundle = getIntent().getExtras();
//Extract the data…
String name = bundle.getString(“cocktail_name”);
TextView t1 = (TextView)findViewById(R.id.textCocktailName);
t1.setText(name);

Try this in Menu activity:
// React to user clicks on item
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parentAdapter, View view, int position,
long id) {
// here you get the Item selected using position
Intent i = new Intent(MenuActivity.this, CocktailDetails.class);
i.putExtra("title", your_title_cocktail);
startActivity(i);
}
});
in the DetailActivity
protected void onCreate(Bundle savedInstanceState) {
Intent i = getIntent();
---
}
give a look here and here.
