Question

Both phone and emulator are 2.2.

Trying to create a gridview with a custom SimpleCursorAdapter class. The gridview contains a image and text view.

The code below works perfectly on the emulator but nothing shows up when I try it on the phone.

I have noticed that only the constructor is called from the phone (not newView or bindView)! Any help?

public class GridAdapter extends SimpleCursorAdapter {
       private Context context; 
       private int mLayout;

       public GridAdapter(Context context, int layout, Cursor c,
            String[] from, int[] to) {
           super(context, layout, c, from, to);

           this.context = context;
           mLayout = layout;

        }

       @Override
       public View newView(Context context, Cursor cursor, ViewGroup parent) {
           Cursor c = getCursor();

           final LayoutInflater inflater = LayoutInflater.from(context);
           View v = inflater.inflate(mLayout, null);

           v.setLayoutParams(new GridView.LayoutParams(150,150));


           return v;

       }

       @Override
       public void bindView(View v, Context context, Cursor c) {

           int nameCol = c.getColumnIndex("show_title");

           String name = c.getString(nameCol);


           TextView tv = (TextView) v.findViewById(R.id.textView1);
           if (name != null) {

               tv.setText(name);
           }

           ImageView iv = (ImageView) v.findViewById(R.id.album_image);
           iv.setScaleType(ImageView.ScaleType.CENTER_CROP);
           iv.setImageResource(R.drawable.icon);
       }

    }

Here is my main xml file:

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/gridview"
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:columnWidth="90dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>

Here is my view for each grid position:

<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"            
  android:id = "@+id/single_item_id"  
  android:layout_width="fill_parent"
 android:layout_height="fill_parent"      
 android:orientation="vertical"
 > 
  <ImageView
  android:id = "@+id/album_image"
  android:adjustViewBounds="true"
  android:layout_width = "fill_parent"             
  android:layout_height="wrap_content"/>

  <TextView 
  android:text="TextView" 
  android:id="@+id/textView1" 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content"/>

 </LinearLayout>

And finally here is my onCreate(well some of it):

gridview = (GridView) findViewById(R.id.gridview);
Cursor c = mDbHelper.fetchAllShows();
int[] to = new int[] {R.id.name};
GridAdapter ga = new GridAdapter(this,R.layout.icon,c,new String[] {"show_title"},
            to);
gridview.setAdapter(ga);

(and yes, I know I am doign nothing with the imageview inside of each position yet).

Answer 1

I ended up taking Herrmann’s advice here. I removed the reference to the context and to the cursor. Also renamed the gridview in my layout and changed the appropriate references in my code.
