Android: how to programmatically set width of ImageView inside TableRow

How do you programmatically set the width of an ImageView inside a TableRow? I do NOT want the cell width to change, only the width of the image inside the cell.

Layout: (The ellipsis are there to reduce the code)

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal">
<TableRow android:gravity="center_vertical">
<Button>...</Button>
<ImageView
    android:id="@+id/fruit"
    android:layout_width="120dp"
    android:layout_height="44dp"
    android:src="@drawable/apple"
    android:scaleType="matrix"
></ImageView>
<Button>...</Button>
</TableRow>
<TableRow>...</TableRow>
</TableLayout>

Java:

ImageView iv = (ImageView) findViewById(R.id.fruit);
LayoutParams frame = iv.getLayoutParams();
frame.width = 100;
iv.setLayoutParams(frame);

EDIT: i want the image to be cropped inside the bounds i set and have the table cell be the original width. Below is the code example that worked for me thanks to parag's suggestion:

Bitmap bmp = BitmapFactory.decodeResource(getResources() , R.drawable.apple); 
int width = 50;
int height = 44; 
Bitmap resizedbitmap = Bitmap.createBitmap(bmp, iv.getScrollX(), iv.getScrollY(), width, height);
iv.setImageBitmap(resizedbitmap);

Another way that u resized the bitmap 

    ImageView img=(ImageView)findViewById(R.id.ImageView01);
    Bitmap bmp=BitmapFactory.decodeResource(getResources(), R.drawable.sc01);
    int width=200;
    int height=200;
    Bitmap resizedbitmap=Bitmap.createScaledBitmap(bmp, width, height, true);
    img.setImageBitmap(resizedbitmap);

Do you want to scale the image? Or crop it?

To scale, try ImageView.setImageMatrix and Matrix.preScale.

If you don't want to figure out the Matrices, you could try Rects (bounding boxes). Get the original rect with ImageView.getDrawingRect and then define whatever Rect you want and use Matrix.setRectToRect to create your image matrix.

Otherwise, have you tried ImageView.setMaxWidth?
