    <p>I have my simple custom listview layout defined in XML. sometimes after edditing content of this listview and after calling method listviewAdapter.notifyDataSetChanged(); I got my listview distorted: </p> <p><img src="https://i.stack.imgur.com/A50mQ.png" alt="enter image description here"></p> <p>in this snapshot the first entry in a list view should be centred like rest of the entries. this happens in the random position in the listview... Here goes XML definition of the listview...</p> <pre><code> &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/Black" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" tools:context=".MainActivity" &gt; &lt;View android:id="@+id/remelis1" android:layout_width="wrap_content" android:layout_height="3dp" android:layout_alignLeft="@+id/Gaminys" android:layout_alignParentTop="true" android:background="@drawable/remelis" /&gt; &lt;TextView android:id="@+id/Gaminys" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/remelis1" android:layout_centerHorizontal="true" android:gravity="center" android:padding="@dimen/dp2" android:text="Large Text" android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="@color/Orange" /&gt; &lt;TextView android:id="@+id/plotis" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignLeft="@+id/Gaminys" android:layout_below="@+id/Gaminys" android:gravity="right" android:paddingBottom="@dimen/dp2" android:paddingLeft="@dimen/dp2" android:paddingRight="@dimen/dp2" android:paddingTop="@dimen/dp2" android:text="Small Text" android:textAppearance="?android:attr/textAppearanceSmall" android:textColor="@color/Orange" /&gt; </code></pre> <p></p> <p>EDIT: I define listView items and adapter in fallowing way:</p> <pre><code> String[] gaminiai = new String []{ "040 319 00", "040 342 00", "040 419 00", " 040 565 00", "040 566 00", "040 792 00", "040 847 00", " 041 082 00", "041 283 00", "041 284 00", "041 400 00", "041 800 00"}; double [] plotis = new double [] {160.0 , 190.5, 185.3 , 90.0, 252.0, 190.0, 302.3, 140.8, 55.5, 100.0 , 110.5 , 125.0 }; for (int i=0; i&lt;=11; i++){ arrayWidith.add(new Plotis(gaminiai[i], plotis[i])); } widithAdapter = new myAdapter(this, R.layout.my_list_view, arrayWidith); myListView.setAdapter(widithAdapter); </code></pre> <p>Listener for a listview:</p> <pre><code> myListView.setOnItemLongClickListener(new OnItemLongClickListener() { public boolean onItemLongClick(AdapterView&lt;?&gt; arg0, View arg1, int pos, long id) { arrayWidith.remove(pos); widithAdapter.notifyDataSetChanged(); return true; } }); </code></pre> <p>"Plotis" is my Class representin object with two fields - string and double. myAdapter is basicly copy/paste from some tutorial from the web and it is defined like this:</p> <pre><code> public class myAdapter extends ArrayAdapter { Context mContext; int layoutResourceId; ArrayList&lt;Plotis&gt; mData = null; public myAdapter(Context mContext, int layoutResourceId, ArrayList&lt;Plotis&gt; data) { super(mContext, layoutResourceId, this.layoutResourceId = layoutResourceId; this.mContext = mContext; mData = data; } @Override public View getView(int position, View convertView, ViewGroup if(convertView==null){ // inflate the layout LayoutInflater inflater = ((Activity) mContext).getLayoutInflater(); convertView = inflater.inflate(layoutResourceId, parent, false); } Plotis plotis = mData.get(position); // get the TextView and then set the text (item name) and tag (item ID) values TextView textViewItem = (TextView) convertView.findViewById(R.id.Gaminys); textViewItem.setText(plotis.getStringGaminys()); textViewItem = (TextView) convertView.findViewById(R.id.plotis); textViewItem.setText(plotis.getStringPlotis()); return convertView; } } </code></pre> <p>What did I do wrong?? thanks.</p>

    1. COAs you mention that this is triggered by `notifyDatatsetChanged()`, it leads me to believe that you are experiencing troubles with recycling your views. Can you provide some code as to how you've defined the list items and the list adapter?

Guidance
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).
