    <p>I have a <code>GridView</code> with images. On long click the screen gets dark (with black half transparent image that gets visible) and another image become visible that has the same resource of the image long clicked from the grid.</p> <p>What i want is to be able to drag that image (which i have succeeded), but the image shows at the top corner (as i designed the layout in the XML) and I want it to show up where I clicked (To be precised, i want the center of the dragable picture to be where I perfumed the long click).</p> <p>My image is <code>fill_parent</code> on <code>FrameLayout</code> and is set on matrix scale to control position...</p> <p>this is the image part of the XML:</p> <pre><code>&lt;ImageView android:id="@+id/imgMainSelectedMovie" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scaleType="matrix" android:visibility="invisible" android:src="@drawable/escape" /&gt; </code></pre> <p>and this is the <code>OnTouch()</code> part:</p> <pre><code>public boolean onTouch(View v, MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: X = ev.getX(); Y = ev.getY(); if (longClicked) return true; break; case MotionEvent.ACTION_MOVE: if (longClicked) { if (!dragStarted) { dragStarted = true; myImageView.setX(X); myImageView.setY(Y); } matrix.postTranslate((ev.getX() - X), (ev.getY() - Y)); X = ev.getX(); Y = ev.getY(); myImageView.setImageMatrix(matrix); return true; } break; case MotionEvent.ACTION_UP: if (longClicked) { dark.setVisibility(View.INVISIBLE); myImageView.setVisibility(View.INVISIBLE); longClicked = false; return true; } } return false; } </code></pre> <p>thist is what I tried to solve the problem:</p> <pre><code>if (!dragStarted) { dragStarted = true; //Changed to true when OnItemLongClick called myImageView.setX(X); myImageView.setY(Y); } </code></pre> <p>But it only changes the "start point" of the image layout to the entered X and Y.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
