    <p>I'm struggling to finish my Android app, but I'm having some problems with the UI. My problem is very basic, I've developed the UI using the default AVD when using AVD manager in Eclipse (HVGA, with a density of 160 dpi), and when I execute the app I see it as I designed, but if I change the target device (i.e. WVGA or QVGA) all the components in the layout are in a different position than the original. As far as I saw in the recommendations for support multiple screens, I should not use AbsoluteLayouts, in fact I'm using RelativeLayouts, I'm not using "px" for the dimensions (or positions), just "wrap_content" or "fill_parent", and in case I need an specific position I'm using "dp" (tested too with "sp"), also I've scaled the images for ldpi (0.75x), and still have the issue (not a particular screen, the hole app) ...so, my question is, is there any other UI tip that I'm missing?.<br/> I'm putting a sample code and the results that I observe when testing it with a HVGA AVD (bigger image) and with a QVGA AVD. As you can see, the position of the yellow/green squares is different, as well as the size of the last row of images.<br/> PS: I'm using a TabLayout also, so the background is loaded through code (tabHost.setBackgroundDrawable(getResources().getDrawable(R.drawable.background1))) <br/>Any help will be appreciated.</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" android:id="@+id/row1" android:layout_centerHorizontal="true" android:layout_marginTop="140dp" &gt; &lt;ImageView android:id="@+id/btn1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:clickable="true" android:onClick="method1" android:src="@drawable/button1" /&gt; &lt;ImageView android:id="@+id/btn2" android:layout_height="wrap_content" android:layout_width="wrap_content" android:clickable="true" android:onClick="method1" android:src="@drawable/button2" /&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_below="@id/row1" android:layout_centerHorizontal="true" &gt; &lt;ImageView android:id="@+id/btn3" android:layout_height="wrap_content" android:layout_width="wrap_content" android:clickable="true" android:onClick="method1" android:src="@drawable/button3" /&gt; &lt;ImageView android:id="@+id/btn4" android:layout_height="wrap_content" android:layout_width="wrap_content" android:clickable="true" android:onClick="method1" android:src="@drawable/button4" /&gt; &lt;/LinearLayout&gt; &lt;/RelativeLayout&gt; </code></pre> <p><img src="https://i.stack.imgur.com/MraYO.png" alt="screen at 240x320"> <img src="https://i.stack.imgur.com/eKttw.png" alt="screen at 320x480"></p>

    1. COAdd your drawables, because I do not understand the changing sizing of the bottom boxes. Also, that white box is not in your example layout.

    2. COHi @Kaediil, thanks for your quick response, the white box is part of the background, sorry not to mention that before. Regarding the drawables, I'll add them soon, for now I don't know if it helps, but the size of the green/yellow boxes are 50x50 in case of mdpi and 38x38 in case of ldpi, and for the background the size is 240x360 (ldpi) and 320x480(mdpi). The attached images are just a cut of the screen.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
