java - Error: SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length -

i got problem android app. got button , and event associated , when click first time error appears

"spans cannot have 0 lenght".

. when click second time, event onclick runs well.. @ java code:

public class mainactivity extends activity { @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      final button selectaltitude = (button) findviewbyid(r.id.buttonaltitude1);     final button selectaltitude2 = (button) findviewbyid(r.id.buttonaltitude2);       selectaltitude2.setonclicklistener(new view.onclicklistener() {         public void onclick(view view){                  string tempalt = selectaltitude2.gettext().tostring();                 selectaltitude2.settext(selectaltitude.gettext().tostring());                 selectaltitude.settext(tempalt);         }     });     } 

the xml code 2 buttons (a deprecated warning occurs):

 <?xml version="1.0" encoding="utf-8"?>  <absolutelayout   xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"   android:background="@android:color/black">   <button         android:id="@+id/buttonaltitude1"         style="?android:attr/buttonbarbuttonstyle"         android:layout_width="39dp"         android:layout_height="42dp"         android:layout_marginleft="250dp"         android:layout_x="257dp"         android:layout_y="419dp"         android:background="@drawable/drawable1"         android:focusableintouchmode="true"         android:gravity="center_vertical"         android:includefontpadding="false"         android:linksclickable="true"         android:minheight="10dp"         android:minwidth="64dp"         android:paddingleft="10dp"         android:paddingright="5dp"         android:scrollhorizontally="true"         android:text="@string/button_meters"         android:textcolor="@android:color/black"         android:textsize="22sp"         android:textstyle="bold" />          <button             android:id="@+id/buttonaltitude2"             style="?android:attr/buttonbarbuttonstyle"             android:layout_width="65dp"             android:layout_height="42dp"             android:layout_marginleft="250dp"             android:layout_x="295dp"             android:layout_y="419dp"             android:background="@drawable/drawable2"             android:clickable="true"             android:focusableintouchmode="true"             android:gravity="center_vertical"             android:includefontpadding="false"             android:linksclickable="true"             android:minheight="10dp"             android:minwidth="64dp"             android:paddingleft="15dp"             android:paddingright="5dp"             android:scrollhorizontally="true"             android:text="@string/button_feet"             android:textcolor="@android:color/black"             android:textsize="25sp"             android:textstyle="bold" /> 

when click first time log cat interacts with:

04-06 20:01:39.865: i/sensors(6946): senddelay --- 200000000 04-06

20:01:39.865: d/sensormanager(6946): jni - senddelay 04-06

20:01:39.865: i/sensormanager(6946): set normal delay = true 04-06

20:01:39.890: e/spannablestringbuilder(6946): span_exclusive_exclusive

spans cannot have 0 length 04-06 20:01:39.890:

e/spannablestringbuilder(6946): span_exclusive_exclusive spans cannot

have 0 length

can ne?;)

i have run same error entries in logcat. in case it's caused 3rd party keyboard using. when change android keyboard, error entry not show more.
