Android-如何以编程方式设置AlertDialog图标的颜色？

Question

I want to use the same icon (which is a vector ) with various colors by programmatically setting its color as we do thanks to the android:tint property.

Here is the builder that sets the icon of AlertDialog :

builder.setIcon(android.R.drawable.ic_dialog_info);

Is there a way to do that? Do we have to create the same icon again if we just want to use it with a different color?

You can get the ImageView and set the ColorFilter . try the code below. See if it works as expected.

            AlertDialog.Builder builder = new AlertDialog.Builder(DemoActivity.this);
            builder.setMessage("Message");
            builder.setTitle("Title");
            builder.setIcon(android.R.drawable.ic_dialog_info);
            AlertDialog dialog = builder.create();
            dialog.show();
            ImageView imageView = dialog.findViewById(android.R.id.icon);
            if (imageView != null)
                imageView.setColorFilter(Color.BLUE, android.graphics.PorterDuff.Mode.SRC_IN);
