    text
    copied!<p>I have a <code>ListView</code> where I've defined the layout of each item in a separate XML file. In this file I've included a <code>RatingBar</code> and an <code>EditText</code>.</p> <p>I've programmatically created 7-8 items in this <code>ListView</code>. When I scroll through them, it seems to be quite buggy. Here are some examples:</p> <ol> <li><p>If I set focus to the <code>EditText</code> in the first row and then scroll down the <code>ListView</code>, random <code>EditTexts</code> from other rows will have focus. It seems to be that the next <code>EditText</code> after the focused one disappears receives focus. Perhaps this is intentional, but, as a user, it seems very weird.</p></li> <li><p>If I set focus to an <code>EditText</code>, receive a virtual keyboard, type something, and click the "Done" button on my virtual keyboard, the <code>EditText</code> will empty as soon as the virtual keyboard disappears.</p></li> <li><p>Sometimes, when I click an <code>EditText</code>, receive a virtual keyboard and start typing letters, the letters will disappear as soon as I type them.</p></li> <li><p>When I click on an <code>EditText</code>, the virtual keyboard shows itself, but the <code>EditText</code> loses focus and I have to click the <code>EditText</code> again.</p></li> <li><p>Even though I've set the <code>RatingBar</code> to <code>focusable="false"</code>, if I move my scrollwheel, it still grabs focus.</p></li> </ol> <p>One of my problems is all the visible list items get redrawn when I type a character in the virtual keyboard (and since the text of the <code>EditText</code> is set to some data, which is empty, it gets cleared. I don't understand why Android would decide to redraw the list every time I type a character.</p> <p>Here is the XML I'm using to draw them. They are white bubbles, with a gray boarder, and some text, a <code>RatingBar</code> and an <code>EditText</code> inside:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingTop="10dip" android:paddingBottom="10dip" android:paddingLeft="15dip" android:paddingRight="15dip" &gt; &lt;LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="2dip" android:background="@drawable/shape_outer"&gt; &lt;LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="2dip" android:background="@drawable/shape_inner"&gt; &lt;TextView android:id="@+id/rating_category" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="@color/dark_gray" android:textStyle="bold" android:layout_marginBottom="10dip" /&gt; &lt;RatingBar android:id="@+id/rating_rating" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numStars="5" android:rating="0" android:stepSize="1" android:focusable="false" android:clickable="false" /&gt; &lt;EditText android:id="@+id/rating_text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_column="1" android:padding="6dip" android:textColor="#000000" android:gravity="left|top" android:lines="3" android:hint="Comment" android:imeOptions="actionDone" /&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre>
