Android Question

Adding a view to a LinearLayout at a specified position

I have the following main.xml file with a LinearLayout

<?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"
android:weightSum="1" android:id="@+id/llid">
<TextView android:text="Client profile"
android:id="@+id/ProfileName"
android:layout_width="fill_parent"
android:textStyle="bold"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
</TextView>
<TextView android:text="Specs"
android:id="@+id/Specs"
android:layout_width="fill_parent"
android:textStyle="bold"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
</TextView>
</LinearLayout>


I add an image to the LinearLayout via code at runtime like so

ImageView image = new ImageView(this);
image.setImageBitmap(bmp);
LinearLayout ll = (LinearLayout) findViewById(R.id.llid);
ll.addView(image);


However, I want to add the ImageView between the 2 TextViews in my LinearLayout. I can't seem to find a way in the android docs to add a view before another view, or after. How can I do this?

NB I call

setContentView(R.layout.main);


Before I add the ImageView to the LinearLayout.

Answer

When adding a View to a ViewGroup, you can specify an index which sets the position of the view in the parent.

You have two views and so (counting from zero) you would want to add at the 1st position; just call ll.addView(image, 1); to have it placed in between the two TextViews.
