How to programatically set drawableLeft on Android button?

I'm dynamically creating buttons. I styled them using XML first, and I'm trying to take the XML below and make it programattic.

<Button
android:id="@+id/buttonIdDoesntMatter"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:text="buttonName"
android:drawableLeft="@drawable/imageWillChange"
android:onClick="listener"
android:layout_width="fill_parent">
</Button>


This is what I have so far. I can do everything but the drawable.

linear = (LinearLayout) findViewById(R.id.LinearView);
Button button = new Button(this);
button.setText("Button");
button.setOnClickListener(listener);
button.setLayoutParams(
new LayoutParams(
android.view.ViewGroup.LayoutParams.FILL_PARENT,
android.view.ViewGroup.LayoutParams.WRAP_CONTENT
)
);

linear.addView(button);

Answer

You can use the setCompoundDrawables method to do this. See the example here. I used this without using the setBounds and it worked. You can try either way.

UPDATE: Copying the code here incase the link goes down

Drawable img = getContext().getResources().getDrawable( R.drawable.smiley );
img.setBounds( 0, 0, 60, 60 );
txtVw.setCompoundDrawables( img, null, null, null );

or

Drawable img = getContext().getResources().getDrawable( R.drawable.smiley );
txtVw.setCompoundDrawablesWithIntrinsicBounds( img, null, null, null);

or

txtVw.setCompoundDrawablesWithIntrinsicBounds( R.drawable.smiley, 0, 0, 0);
