Trouble is adding multi Edit Text Views

Question

I am trying to add five Edit Text Views on the click of a button in a Scroll View. But when i am clicking the button, the Edit Text View appearing is not in the Scroll View but in the Main Linear Layout.
What to do, for Edit Text View to get appear in Scroll View.

Answer 1

Add edittext in scrollview ScrView.addView(tab)

Answer 2

ScrollView must have a child layout to add any view to it.

Add your textview to the linear layout Add a LinearLayout to Scrollview. Add scrollview to your parent layout

This is the xml

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainl"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button" />

<ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <LinearLayout
        android:id="@+id/scLay"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >
    </LinearLayout>
</ScrollView>

</LinearLayout>

This is the activity java class

    LinearLayout l,scl;
    Button b1;
EditText e1,e2,e3,e4,e5;
ScrollView sv;
    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    l = (LinearLayout) findViewById(R.id.mainl);
    scl=(LinearLayout) findViewById(R.id.scLay);
    sv=(ScrollView)findViewById(R.id.scrollView1);
    b1=(Button)findViewById(R.id.button1);
    e1=new EditText(this);  
    e2=new EditText(this);  
    e3=new EditText(this);  
    e4=new EditText(this);  
    e5=new EditText(this);  
    b1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            scl.addView(e1);
            scl.addView(e2);
            scl.addView(e3);
            scl.addView(e4);
            scl.addView(e5);
        }
    });
}
