Programmatically set left drawable in a TextView

Question

I have a textView in xml here.

<TextView
        android:id="@+id/bookTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:drawableLeft="@drawable/checkmark"
        android:gravity="center_vertical"
        android:textStyle="bold"
        android:textSize="24dip"
        android:maxLines="1"
        android:ellipsize="end"/>

As you can see I set the DrawableLeft in xml.

I would like to change the drawable in code.

Is there anyway to go about doing this? Or setting the drawableLeft in code for the text view?

Answer 1

You can use setCompoundDrawablesWithIntrinsicBounds(int left, int top, int right, int bottom)

set 0 where you don't want images

Example for Drawable on the left:

TextView textView = (TextView) findViewById(R.id.myTxtView);
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon, 0, 0, 0);

Alternatively, you can use setCompoundDrawablesRelativeWithIntrinsicBounds to respect RTL/LTR layouts.

Tip: Whenever you know any XML attribute but don't have clue about how to use it at runtime. just go to the description of that property in developer doc. There you will find Related Methods if it's supported at runtime . i.e. For DrawableLeft
