Is it possible to set drawableLeft programmatically?

Question

In XML we can set drawableLeft using this way:

    <Button
    android:id="@+id/previewBtn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/white_btn"
    android:drawableLeft="@drawable/green_circle"
    android:drawablePadding="16dp"
    android:text="Button" />

How to do same thing programmatically?

Answer 1

Yes, use setCompoundDrawablesWithIntrinsicBounds

and define the drawable for the first parameter, then 0 for all the others.

The code should look something like this:

Button b = findViewById(R.id.myButton);

b.setCompoundDrawablesWithIntrinsicBounds(R.drawable.myDrawable, 0, 0, 0);

If your drawable was created in code as well then you need to use the other setCompoundDrawablesWithIntrinsicBounds method which takes 4 drawables, and pass null for all but the left.

Answer 2

The method to use is setCompoundDrawablesWithIntrinsicBounds. This method takes all four drawable options (left, top, right, bottom), so if you want only left, pass in null for the others.
