show data in my android app(saving works just fine now)

hey, now i can save data in my db, but it doesn't show up in the database activity itself.

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); onCreateDBAndDBTabled(); //DB und Tables erstellen wenn noch nicht vorhanden setContentView(R.layout.main); }

private void onCreateDBAndDBTabled() {
    myDB = this.openOrCreateDatabase(MY_DB_NAME, Context.MODE_PRIVATE, null);
    myDB.execSQL("CREATE TABLE IF NOT EXISTS " + MY_DB_TABLE
                + " ( id integer primary key autoincrement,"+ 
                      "Name varchar(100),"+ 
                      "Comment varchar(128),"+ 
                      "BookingDetails varchar(255),"+ 
                      "CustomerProject integer(3),"+ 
                      "editable varchar(15))"
                +";");

    }


public boolean onCreateOptionsMenu(Menu menu) {
      super.onCreateOptionsMenu(menu);

        menu.add(0, MENU_PROJECTS, 0, R.string.menuProjects)
        .setShortcut('1', 'f')
        .setIcon(R.drawable.icon);
         return true;

      }

public boolean onOptionsItemSelected(MenuItem item){
      switch (item.getItemId()) {
      case MENU_PROJECTS:
        Intent iProjects = new Intent(this, Projects.class);
        startActivity(iProjects);
        return true;
      }
      return false;
    }

}

This is the insert statement

{

                        ContentValues cv = new ContentValues(); 
                        cv.put ( "Name", Name.getText().toString() ); 
                        cv.put ( "Comment", Comment.getText().toString() ); 
                        cv.put ( "BookingDetails", BookingDetails.getText().toString() ); 
                        cv.put ( "Project_kind", i ); 
                        cv.put ( "Editable", Editable.getText().toString() ); 
                        myDB.insert ( Projectshome.MY_DB_TABLE , null, cv); 
                    }
                    finish();
                    return true;
this is my manifest:

</manifest> 

here is my LogCat-output the moment i hit the save-button:

hope you can help me again :)

Please provide more information. As in the error log. The error might be in the statement itself.Add the details from the logcat first.It will clarify.

I think the insert query is missing word 'values'. Try printing that query string on console executing the same through console on db. That may help you identify error.

I have two things to point out:

What is i in your SQL query? Is it an int? If so that might be the problem because the way you are using it, it should be a String.

Secondly, why don't you use the insert convenience function of SQLiteDatabase?

ContentValues cv = new ContentValues();
cv.put ( "Name", Name.getText().toString() );
cv.put ( "Comment", Comment.getText().toString() );
cv.put ( "BookingDetails", BookingDetails.getText().toString() );
cv.put ( "Project_kind", i );
cv.put ( "Editable", Editable.getText().toString() );
myDB.insert ( Projectshome.MY_DB_TABLE, null, cv );

This takes all the complexity of building the SQL query out of inserting rows - it will ensure that the query is correctly built, all you have to do is build the ContentValues map properly.

OK, so here's how I do it:

row.xml (Used for each row in the list view):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="4px"
    >
    <LinearLayout
        android:id="@+id/LinearLayout01"
            android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <TextView android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_vertical"
            android:textStyle="bold"
            android:singleLine="true"
            android:ellipsize="end"
            android:id="@+id/itemDescription"/>
        <TextView
            android:text="@+id/TextView01"
            android:id="@+id/Category"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
        </TextView>
    </LinearLayout>
    <LinearLayout
        android:id="@+id/LinearLayout01"
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <TextView
            android:layout_width="fill_parent"
            android:text="@+id/TextView01"
            android:gravity="center_vertical"
            android:layout_weight="1"
            android:singleLine="true"
            android:ellipsize="end"
            android:id="@+id/itemManufacturer"
            android:layout_height="wrap_content">
        </TextView>
        <TextView
            android:text="@+id/TextView01"
            android:id="@+id/EAN"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
        </TextView>
    </LinearLayout>
</LinearLayout>

I extend CursorAdapter to create or re-use existing ListActivity rows (supplied by the ListActivity) defined in row.xml. bindView is used if Android wants you to re-use an existing row resource, newView is used if it wants you to create a new one:

class BarcodeAdapter extends CursorAdapter {
    BarcodeAdapter(Cursor c) {
        super(kitchenListInventoryActivity.this, c);
    }

    @Override
    public void bindView(View row, Context ctxt,
                                             Cursor c) {
        BarcodeHolder holder=(BarcodeHolder)row.getTag();
        holder.populateFrom(c, helper);
    }

    @Override
    public View newView(Context ctxt, Cursor c,
                                             ViewGroup parent) {
        LayoutInflater inflater=getLayoutInflater();
        View row = null;
        row = inflater.inflate(R.layout.row, parent, false);
        BarcodeHolder holder=new BarcodeHolder(row);

        row.setTag(holder);

        return(row);
    }
}

BarcodeHolder is just a convenience class to hold a Java representation of the row, which I associate with the ListActivity item with setTag above. Not necessarily the most elegant way, but it simplifies things.:

    static class BarcodeHolder {
        private TextView description=null;
        private TextView manufacturer=null;
        private TextView EAN = null;
        private TextView category = null;
        private View row=null;

        BarcodeHolder(View row) {
            this.row=row;

            description=(TextView)row.findViewById(R.id.itemDescription);
            manufacturer=(TextView)row.findViewById(R.id.itemManufacturer);
            EAN=(TextView)row.findViewById(R.id.EAN);
            category = ( TextView )row.findViewById(R.id.Category);
        }

        void populateFrom(Cursor c, BarcodeHelper helper) {
            Cursor invCursor = helper.getByInventoryEAN(helper.getBarcode(c));
            Cursor dbCursor = helper.getByEAN(helper.getBarcode(c));
            dbCursor.moveToFirst();
            invCursor.moveToFirst();
            int qty = helper.getQuantity ( invCursor );
            String desc = helper.getDescription(dbCursor) + " (" + String.valueOf( qty ) + ")" ;
            description.setText( desc );
            manufacturer.setText(helper.getManufacturer(dbCursor));
            category.setText(helper.getCategory(dbCursor));
        }
    }

To bring this all together, I call initList in my onCreate of the ListActivity:

private void initList ( ) {
    if ( model != null ) {
        stopManagingCursor(model);
        model.close();
    }

    model = helper.getAllInventory();
    startManagingCursor(model);
    adapter = new BarcodeAdapter(model);
    setListAdapter(adapter);
}

model is a Cursor, and adapter is an instance of BarcodeAdapter, which I've shown above. I tell the ListActivity to use this adapter so that I can correctly populate the rows. getAllInventory is a member of BarcodeHelper which overrides SQLiteOpenHelper:

public Cursor getAllInventory( ) {
    String sql = "SELECT _id, EAN, quantity FROM Inventory ORDER BY EAN";
    return(getReadableDatabase().rawQuery(sql, null));
}

The helper object just contains a collection of convenience functions.

All of this is based on CommonsWare's excellent Android tutorial book which I cannot recommend enough, but there should be enough here to get you going.
