    copied!<p>im calling my layout and setting items for it but the getview() returns nothing .</p> <p>My main class :</p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.MymainView); grid = (GridView) findViewById(R.id.grid); if (getScreenOrientation() == 1) grid.setNumColumns(3); else grid.setNumColumns(4); items = new ArrayList&lt;LauncherGridItem&gt;(); Intent intent = new Intent(this, Activity2.class); intent.putExtra("Param1", "Child Activity"); items.add(new LauncherGridItem("ic_launcher", "Item 1", intent)); adapter = new LauncherGridAdapter(this, items, grid, dragLayer, deleteZone); adapter.setPersistenceToken("MyLauncherGrid"); adapter.setDragListener(this); adapter.setEditable(true); grid.setAdapter(adapter); </code></pre> <p>And My LauncherGridAdapter , getview() section in file :</p> <pre><code> public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = inflater .inflate(R.layout.grid_view_item_layout, null); holder = new ViewHolder(); holder.image = (ImageView) convertView .findViewById(R.id.selection_item_image); holder.text = (TextView) convertView .findViewById(R.id.selection_item_text); convertView.setTag(holder); //holder.image.setPadding(8, 8, 8, 8); } else { holder = (ViewHolder) convertView.getTag(); } DraggableRelativeLayout layout = (DraggableRelativeLayout) convertView; convertView.setOnLongClickListener(this); convertView.setOnClickListener(this); LauncherGridItem item = getItems().get(position); layout.setItem(item); layout.setDragListener(this); // holder.image.setOnLongClickListener(this); Drawable d = holder.image.getDrawable(); // if (d != null) { d.setCallback(null); // } holder.image.setImageDrawable(null); if (!item.getUrl().startsWith("http")) { try { holder.image.setImageDrawable(context.getResources() .getDrawable( context.getResources().getIdentifier( context.getApplicationContext() .getPackageName() + ":drawable/" + item.getUrl(), null, null))); } catch (NotFoundException e) { holder.image.setImageResource(android.R.drawable.ic_menu_view); } } else { // Image cached = images.get(position); if(item.getImage() == null) { holder.image.setImageResource(R.drawable.avatar); } else { holder.image.setScaleType(ScaleType.CENTER_INSIDE); holder.image.setImageBitmap(item.getImage()); } } } holder.text.setText(item.getCaption()); layout.setImage(holder.image); layout.setText(holder.text); layout.setItem(item); layout.canDelete(item.canDelete()); return convertView; </code></pre> <p>}</p> <p>i even checked the if statement and program items are valid and not null. ive also added these but still nothing in gridview :</p> <pre><code>@Override public int getCount() { return getItems().size(); } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { </code></pre> <p>i guess the problem is "grid_view_item_layout" not showing at all </p> <p>this is the "main" layout :</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="#CCCCCC"&gt; &lt;com.myapp.ui.drag.DragLayer xmlns:android="http://schemas.android.com/apk/res/android" xmlns:launcher="http://schemas.android.com/apk/res/com.android.launcher" android:id="@+id/drag_layer" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_above="@+id/handle"&gt;

&lt;/LinearLayout&gt; </code></pre> <p>and this is grid_view_item_layout layout :</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;com.myapp.ui.drag.DraggableRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@color/CadetBlue" android:orientation="vertical" &gt;

&lt;TextView android:layout_width="wrap_content" android:id="@+id/selection_item_text" android:maxLines="1" android:lines="1" android:scrollHorizontally="true" android:ellipsize="end" android:layout_height="wrap_content" android:textColor="@android:color/black" android:text="(Selection Text)" android:layout_below="@+id/selection_item_image" android:layout_centerHorizontal="true" &gt;&lt;/TextView&gt; &lt;/com.myapp.ui.drag.DraggableRelativeLayout&gt; </code></pre> <p>im using plusgridlayout for moving items between gridview . the function works on source project but when i try to release it under mine no error happen plus no gridview at all.</p> <p>also if i change the last line of getview() from return convertView; to return layout; still nothing apears.</p>
