Android X,Y determination of an Image

I am using the following xml for Layout.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingLeft="10dip"
    android:paddingRight="10dip"
    android:paddingBottom="20dip"
    tools:context=".ZoneSelectionActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:paddingTop="10dip"
        android:textSize="35sp"
        android:paddingBottom="10dip"
        android:text="@string/affected_zone" />

    <FrameLayout
        android:id="@+id/imageHolder"
        android:layout_gravity="center"
        android:background="#0B3861"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <ImageView
                android:id="@+id/subsegment"
                android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
                android:contentDescription="subsegment"
                android:src="@drawable/sub_segment01" />

    </FrameLayout>  

</LinearLayout>

And here is my screen-shot. I want to the coordinate of the marked point(x,y of top-left corner of the image) in the screen. How it can be determine?

Try

View v;
int x = v.getLeft();
int y = v.getTop();

I'm not sure ImageView provides a way to get the location of its image on screen.

You can only query the location of the ImageView itself.

Try using ImageView.getImageMatrix() but I'm not sure if it's populated when the image is centered (not scaled)

Use View.getLocationOnScreen().You can only invoke it AFTER layout phase.

int coords[] = {0,0};
yourImageView.getLocationOnScreen(coords);
int x = coords[0];
int y = coords[1];
