    <p>My MotionEvent and my layout seem to give differing location values and I cannot figure out why. I define an image as follows:</p> <pre><code>&lt;ImageView android:id="@+id/pic" android:layout_width="17dp" android:layout_height="17dp" android:layout_marginLeft="72dp" android:layout_marginTop="72dp" android:src="@drawable/pic" /&gt; </code></pre> <p>This places the image at (144, 144) in pixels on the emulator I'm testing with because it has a density of 2.0. The pixel location is confirmed with log.v and the parent of the image is simply the layout.</p> <p>I have an onTouchListener and in a MotionEvent I check the location of the touch:</p> <pre><code>Log.v("pixelsX", String.valueOf(event.getX())); Log.v("pixelsY", String.valueOf(event.getY())); </code></pre> <p>When I click well above and to the left of the image I set in the XML I get values of 160 and up, which is clearly wrong. That would correspond to a DP location of 80+ even though the click is well before the image. </p> <p>If I try and add an image at a click location image.setX(event.getX()) (tried using setX/setY and params) the image gets placed ~40 pixels below and to the right of the click. There is no extra padding or anything to the image, and I've tried using different images and it is consistent between them. The parents of the images are always the layout and the layout is connected to the ontouchlistener:</p> <pre><code>RelativeLayout layout = (RelativeLayout)findViewById(R.id.activity_mine); layout.setOnTouchListener(touch); </code></pre> <p>So I cannot figure out why there is this difference in location. Any ideas or suggestions?</p> <p>Thanks!</p>

    1. COI'm not familiar with `MotionEvent`, but looks like `getX()`/`getY()` returns the X/Y position relative to the whole screen?

    2. COThe layout would be the whole screen, no? Although I believe getRawX() is the absolute position relative to the whole screen, either way getRawX() and getX() return the same value. The layout is the whole screen though isn't it? I believe getX() returning the same as getRawX() would confirm this since the onTouchListener is set to the layout.

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.
