Adding a view to a LinearLayout at a specified position

Question

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 1

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.

Answer 2

The docs state you can use the index to insert it where you want. I see you are using the signature of the view only, did you try the signature with the index parameter?

public void addView(View child, int index)  

Answer 3

I faced a similar problem. In my case I wanted to add a LinearLayout at last position of another LinearLayout. To accomplish it, I did:

LinearLayout parentLayout = (LinearLayout) findViewById(R.id.parentLayout);
LinearLayout layout = new LinearLayout(this);
layout.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

// add others views to your linear layout

parentLayout.addView(layout, parentLayout.getChildCount());
