How to programmatically set drawableLeft on Androi

Question

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 1

Try this:

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

Answer 2

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);

Answer 3

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);
}

Answer 4

For me, it worked:

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

Answer 5

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

Answer 6

***** 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)
    }

}
