Programmatically set left drawable in a TextView

Viewed 219755

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?

Using Kotlin:

You can create an extension function or just use setCompoundDrawablesWithIntrinsicBounds directly.

fun TextView.leftDrawable(@DrawableRes id: Int = 0) {
   this.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0)
}

If you need to resize the drawable, you can use this extension function.

textView.leftDrawable(R.drawable.my_icon, R.dimen.icon_size)

fun TextView.leftDrawable(@DrawableRes id: Int = 0, @DimenRes sizeRes: Int) {
    val drawable = ContextCompat.getDrawable(context, id)
    val size = resources.getDimensionPixelSize(sizeRes)
    drawable?.setBounds(0, 0, size, size)
    this.setCompoundDrawables(drawable, null, null, null)
}

To get really fancy, create a wrapper that allows size and/or color modification.

textView.leftDrawable(R.drawable.my_icon, colorRes = R.color.white)

fun TextView.leftDrawable(@DrawableRes id: Int = 0, @DimenRes sizeRes: Int = 0, @ColorInt color: Int = 0, @ColorRes colorRes: Int = 0) {
    val drawable = drawable(id)
    if (sizeRes != 0) {
        val size = resources.getDimensionPixelSize(sizeRes)
        drawable?.setBounds(0, 0, size, size)
    }
    if (color != 0) {
        drawable?.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
    } else if (colorRes != 0) {
        val colorInt = ContextCompat.getColor(context, colorRes)
        drawable?.setColorFilter(colorInt, PorterDuff.Mode.SRC_ATOP)
    }
    this.setCompoundDrawables(drawable, null, null, null)
}

A Kotlin extension + some padding around the drawable

fun TextView.addLeftDrawable(drawable: Int, padding: Int = 32) {
    val imgDrawable = ContextCompat.getDrawable(context, drawable)
    compoundDrawablePadding = padding
    setCompoundDrawablesWithIntrinsicBounds(imgDrawable, null, null, null)
}

there are two ways of doing it either you can use XML or Java for it. If it's static and requires no changes then you can initialize in XML.

  android:drawableLeft="@drawable/cloud_up"
    android:drawablePadding="5sp"

Now if you need to change the icons dynamically then you can do it by calling the icons based on the events

       textViewContext.setText("File Uploaded");
textViewContext.setCompoundDrawablesWithIntrinsicBounds(R.drawable.uploaded, 0, 0, 0);

Works for me to change the text view left/right drawable color

for (drawable in binding.tvBloodPressure.compoundDrawablesRelative) {
            if (drawable != null) {
                drawable.colorFilter = PorterDuffColorFilter(
                    ContextCompat.getColor(binding.tvBloodPressure.context, color),
                    PorterDuff.Mode.SRC_IN
                )
            }
        }

I am using like this.

  txtUserName.setCompoundDrawablesWithIntrinsicBounds(
        requireActivity().getDrawable(
            R.drawable.ic_my_account
        ), null, null, null
    )
