Android ListView Item Size Issue

Question

Heres my issue, I'v got 2 activities, one that holds a Listview and an add button that calls another activie that hold a listview and a search pannel, when the user searches a product and press's it, the products gets sent back to the Main activity (the one with the listview and the button) and the product is add'd to the listview.

and this is what i want to solve:

1) after the user finds the product he wants and clicks it, when the MAIN activity reloads it reloads with the keyboard open and i cant get it to not open.

2) Each listview item is huge!, it hold up a almost a full screen and the space between each listview item is to big.

Here's the relavnet codde:

Main Activity:

public class Main extends Activity
{
    public ListView lstView;
    ProductAdapter productListAdapter;
    DBAdaptor mDb;
    ArrayList<Product> products;
    EditText et;
    @SuppressWarnings("unchecked")
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_screen);
        InputMethodManager imm = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
        imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
        openDB();
        Bundle b = this.getIntent().getExtras();
        if(b!=null) 
        {
            products =(ArrayList<Product>) b.getSerializable("products");
            productListAdapter = new ProductAdapter(this, R.layout.shoping_list_row,ArrayListToArray(products));
            lstView = (ListView)findViewById(R.id.main_list);
            lstView.setAdapter(productListAdapter);

        }
    }

    private Product[] ArrayListToArray(ArrayList<Product> products)
    {
        Product[] prods = new Product[products.size()];
        for (int i = 0; i < prods.length; i++)
        {
            prods[i]=products.get(i);
        }
        return prods;
    }

    public void startSearchActivity(View v)
    {
        Intent i = new Intent(this,SearchActivity.class);
        if(products!=null)
        {
            Bundle b = new Bundle();
            b.putSerializable("products", products);
            i.putExtras(b);
        }

        startActivity(i);
    }

    private void openDB()
    {
        mDb = new DBAdaptor(this);  
        mDb.open();

    }
}

Heres the layout for the Main Activity:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:orientation="vertical" >

    <ListView
        android:id="@+id/main_list"
        android:layout_width="fill_parent"
        android:layout_height="0dip"
        android:layout_weight="1"

         >

    </ListView>

    <Button
        android:id="@+id/button1"
        style="@style/AppTheme"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:onClick="startSearchActivity"
        android:text="+"
        android:textColor="#009900"
        android:textSize="50sp" />

</LinearLayout>

Heres the search activity:

Heres the XML for the search activity:

        android:layout_height="wrap_content"
        android:hint="Search products.."
        android:inputType="textVisiblePassword"
        android:onClick="onEditTextClick"/>

    <!-- List View -->
    <ListView
        android:id="@+id/list_view"
        android:layout_width="fill_parent"

I know it's a lot of code, but i figured it's to show you the hole story so you guys can help me.

Thanks a lot to any one who can help me...

Answer 1

Use this in the MainActivity tag of the Manifest file

android:windowSoftInputMode="stateHidden"

Regarding the ListViewItems size, try lowering the height of the views in Items layout.

and the gap between the Items by default must be small. But anyways you can set it this way

android:dividerHeight="2dp"

But after going through your code, Shouldn't you use startActivityForResult in stead of just startActivity in the MainActivity. Or atleast finish() it before going to the SearchActivity.
