Hello friends, I want to zeptat.Vytvořil I have in my application scrollView where I have about 20 buttons
[b] <RelativeLayout xmlns:android=“http://schemas.android.com/apk/res/android”
android:layout_width=“match_parent”
android:layout_height=“match_parent”>
<LinearLayout
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:background="@drawable/aplikace4"
android:orientation=“vertical” >

    &lt;ScrollView
        android:id="@+id/myScroll"
        android:layout_width="fill_parent"
        android:layout_height="423dp"
        android:layout_marginTop="55dp" &gt;
        
        &lt;LinearLayout
            android:id="@+id/scrollLinear"
            android:layout_width="fill_parent"
            android:layout_height="2222dp"
            android:orientation="vertical" &gt;

            &lt;Button
                android:id="@+id/btnAlkohol"
                android:layout_width="fill_parent"
                android:layout_height="60dp"
                android:background="@drawable/carka"
                android:onClick="OnButtonAlkohol"
                android:text="@string/alkohol"
                android:textSize="25sp" /&gt;
  &lt;/LinearLayout&gt;
        
    &lt;/ScrollView&gt;
   
&lt;/LinearLayout&gt;
 &lt;/RelativeLayout&gt;[/b]

Here is just an excerpt, and there is only one .To do when I click on it so I opened a new Layout.Udělal I therefore new class where I want to control every one button. (Again, there is only one)

[b] public class VyberTemata extends Activity {

   Button btnAlkohol;

public void OnButtonAlkohol (View v)
{
   btnAlkohol=(Button)findViewById(R.id.btnAlkohol);
   setContentView(R.layout.aplikace_slova);
} 
}[/b]

Well, when I turn on the application and click on it nothing happens can anyone tell me what I’m doing wrong? At the same time when I use the same code in another command only is there a different layout so it works .does not work just the buttons in ScrollView.thanks for advice
