Android Button always takes two clicks to fire onClick() -

i have relativelayout inside of scrollview contains button , textviews , edittexts.

in xml layout file, defining android:onclick takes 2 clicks of button fire event. button gets focus on first click , fires onclick event on second click. have tried setting focusable , focusableintouchmode both false behavior doesn't change.

here layout file:

<scrollview xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingbottom="@dimen/activity_vertical_margin"     tools:context=".densityactivity" >      <relativelayout         android:layout_width="wrap_content"         android:layout_height="wrap_content" >          <textview         ...          <textview         ...          <textview         ...          <edittext         ...          <button             android:id="@+id/ad_button_calculate"             android:layout_width="112dp"             android:layout_height="wrap_content"             android:layout_below="@id/ad_edit_obs_temp"             android:layout_alignparentright="true"             android:layout_margintop="20pt"             android:paddingleft="6pt"             android:onclick="onclick"             android:focusable="false"             android:focusableintouchmode="false"             android:text="@string/button_calculate" />          <textview         ...      </relativelayout> </scrollview> 

any ideas or suggestions why focusable , focusableintouchmode don't seem anything?

i thought might onclick() method not doing should reduced simple see , behaves same. here simplified onclick():

public void onclick(view view) {      new alertdialog.builder(this).settitle("argh").setmessage("watch out!").setneutralbutton("close", null).show();  } 

ok, found it. was, of course, own mistake. @ end of oncreate method doing this:

// set focus calculate button keyboard won't show automatically  button calcbutton = (button)findviewbyid( r.id.ac_button_calculate ); calcbutton.setfocusable( true ); calcbutton.setfocusableintouchmode( true );  calcbutton.requestfocus(); 

so of course, no matter did in xml file, overriding in code. instead, used hide keyboard:

getwindow().setsoftinputmode( windowmanager.layoutparams.soft_input_state_hidden ); 

which works great.
