[java] How to programmatically 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);

For me, it worked:

button.setCompoundDrawablesWithIntrinsicBounds(com.example.project1.R.drawable.ic_launcher, 0, 0, 0);

Simply you can try this also

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

Add a Kotlin Extension

If you are going to be doing this frequently, adding an extension makes your code more readable. Button extends TextView; use Button if you want to be more narrow.

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

To use the extension, simply call

view.leftDrawable(R.drawable.my_drawable)

Anytime you need to clear, don't pass a param or make another extension called removeDrawables

Try this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
     fillButton[i].setBackground(getBaseContext().getResources().getDrawable(R.drawable.drawable_name));
}
else {
    fillButton[i].setBackgroundColor(Color.argb(255,193,234,203));
}

as @Jérémy Reynaud pointing out, as described in this answer, the safest way to set the left drawable without changing the values of the other drawables (top, right, and bottom) is by using the previous values from the button with setCompoundDrawablesWithIntrinsicBounds:

Drawable leftDrawable = getContext().getResources()
                          .getDrawable(R.drawable.yourdrawable);

// Or use ContextCompat
// Drawable leftDrawable = ContextCompat.getDrawable(getContext(),
//                                        R.drawable.yourdrawable);

Drawable[] drawables = button.getCompoundDrawables();
button.setCompoundDrawablesWithIntrinsicBounds(leftDrawable,drawables[1],
                                               drawables[2], drawables[3]);

So all your previous drawable will be preserved.

• Kotlin Version

Use below snippet to add a drawable left to the button:

val drawable = ContextCompat.getDrawable(context, R.drawable.ic_favorite_white_16dp)
button.setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null)

.

• Important Point in Using Android Vector Drawable

When you are using an android vector drawable and want to have backward compatibility for API below 21, add the following codes to:

In app level build.gradle:

android {
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }
}

In Application class:

class MyApplication : Application() {

    override fun onCreate() {
        super.onCreate()

        AppCompatDelegate.setCompatVectorFromResourcesEnabled(true)
    }

}

Following is the way to change the color of the left icon in edit text and set it in left side.

 Drawable img = getResources().getDrawable( R.drawable.user );
img.setBounds( 0, 0, 60, 60 );
mNameEditText.setCompoundDrawables(img,null, null, null);

int color = ContextCompat.getColor(this, R.color.blackColor);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    DrawableCompat.setTint(img, color);

} else {
    img.mutate().setColorFilter(color, PorterDuff.Mode.SRC_IN);
}

Worked for me. To set drawable at the right

tvBioLive.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_close_red_400_24dp, 0)

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

If you are using drawableStart, drawableEnd, drawableTop or drawableBottom; you must use "setCompoundDrawablesRelativeWithIntrinsicBounds"

edittext.setCompoundDrawablesRelativeWithIntrinsicBounds(0, 0, R.drawable.anim_search_to_close, 0)

Try this:

((Button)btn).getCompoundDrawables()[0].setAlpha(btn.isEnabled() ? 255 : 100);

Might be helpful:

TextView location;
location=(TextView)view.findViewById(R.id.complain_location);
//in parameter (left,top,right,bottom) any where you wnat to put
location.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.arrow,0);

I did this:

 // Left, top, right, bottom drawables.
            Drawable[] drawables = button.getCompoundDrawables();
            // get left drawable.
            Drawable leftCompoundDrawable = drawables[0];
            // get new drawable.
            Drawable img = getContext().getResources().getDrawable(R.drawable.ic_launcher);
            // set image size (don't change the size values)
            img.setBounds(leftCompoundDrawable.getBounds());
            // set new drawable
            button.setCompoundDrawables(img, null, null, null);
