    copied!<p>Tipically you would have this:</p> <pre><code> Activity parent = (Activity) context; dragImage = (ImageView) parent.findViewById(R.id.what_ever_you_defined_on_xml); </code></pre> <p>However, in my case I want "findViewById" to get the id attribute dinamically because I have more than one attribute depending on what kind of OverlayItem the user want on the Map (Open Street Map). I have tried this but my application crash:</p> <pre><code> Activity parent = (Activity) context; View v = parent.getCurrentFocus(); dragImage = (ImageView) parent.findViewById(v.getId()); </code></pre> <p>Any suggestion? Thanks. </p> <hr> <p>More details to add context:</p> <pre><code>public Itemizedoverlay(Drawable defaultMarker, Context context, MapView map) { super(defaultMarker, new DefaultResourceProxyImpl(context)); this.defaultMarker = defaultMarker; this.map = map; // Setup for dragging: // Finds a view that was identified by the id attribute from the XML that was processed in onCreate(Bundle): Activity parent = (Activity) context; View v = parent.getCurrentFocus(); dragImage = (ImageView) parent.findViewById(v.getId()); xDragImageOffset = dragImage.getDrawable().getIntrinsicWidth() / 2; yDragImageOffset = dragImage.getDrawable().getIntrinsicHeight(); } </code></pre> <p>In the XML:</p> <pre><code>&lt;ImageView android:id="@+id/drag1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/symbol1" android:visibility="gone" /&gt; &lt;ImageView android:id="@+id/drag2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/symbol2" android:visibility="gone" /&gt; &lt;ImageView android:id="@+id/drag3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/symbol3" android:visibility="gone" /&gt; &lt;ImageView android:id="@+id/drag4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/symbol4" android:visibility="gone" /&gt; </code></pre>
