How do I add elements dynamically to a view created with XML

Question

I'm trying to add dynamic content to a view that has been created with XML.

I have a view "profile_list" that has a ScrollView that I like to add some elements to.

Here is some code of what I'm trying to do.

// Find the ScrollView  ScrollView sv = (ScrollView) this.findViewById(R.id.scrollView1);  // Create a LinearLayout element LinearLayout ll = new LinearLayout(this); ll.setOrientation(LinearLayout.VERTICAL);  // Add text tv = new TextView(this); tv.setText("my text"); ll.addView(tv);  // Add the LinearLayout element to the ScrollView sv.addView(ll);  // Display the view setContentView(R.layout.profile_list); 

The plan is to add a TableLayout and fill it dynamically and not just a dummy text but first I must get this to work.

Any help is welcome.

Kind Regards Olle

I found the solution!

Stupid me I had left a element in my ScrollView in my XML-file!

Anyway her is a working example:

LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);     View v = inflater.inflate(R.layout.profile_list, null);      // Find the ScrollView      ScrollView sv = (ScrollView) v.findViewById(R.id.scrollView1);      // Create a LinearLayout element     LinearLayout ll = new LinearLayout(this);     ll.setOrientation(LinearLayout.VERTICAL);      // Add text     TextView tv = new TextView(this);     tv.setText("my text");     ll.addView(tv);      // Add the LinearLayout element to the ScrollView     sv.addView(ll);      // Display the view     setContentView(v); 

And the XML-file to match

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent">      <ScrollView          android:id="@+id/scrollView1"          android:clickable="true"          android:layout_weight="1"          android:layout_width="fill_parent"          android:layout_marginBottom="50px"          android:layout_height="fill_parent">     </ScrollView>  </LinearLayout> 

Hope this will help someone. Thanks for all help!

The way that you are adding things to the view is basically right - you just get the container object by its ID and then add them.

It looks like you are setting the content view to be the wrong view though. You should inflate the view, add the children and set it as the content view, or set the content view from a resource ID then do the manipulation. What you are doing is manipulating a view and then adding a different one. Try moving your setContentView(...) to the start of the block.
