android: fit height of DrawableLeft in a textView

Question

I am trying to display a blue line next to a block of text, pretty much like this:

Here's my code:

<TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableLeft="@drawable/blue_line" />

blue_line is a jpg file. a blue rectangle. it displays in its original size regardless of the text in the textview. how can i adjust its height dynamically according to the height of the text? like make it shorter when theres little amount of text and longer when there's more text....

You can try doing it in code by setting bounds for the image

textView1.getViewTreeObserver()
        .addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            Drawable img = ActivityName.this.getContext().getResources().getDrawable(
                R.drawable.blue_line);
            img.setBounds(0, 0, img.getIntrinsicWidth() * textView1.getMeasuredHeight() / img.getIntrinsicHeight(), textView1.getMeasuredHeight());
            textView1.setCompoundDrawables(img, null, null, null);
            textView1.getViewTreeObserver().removeOnGlobalLayoutListener(this);
        }
    });
