How to set support library snackbar text color to something other than android:textColor?

Question

So I\'ve started using the new Snackbar in the Design Support Library, but I found that when you define \"android:textColor\" in your theme, it applies to the text color of the

Answer 1

This is my workaround to solve this type of problem in androidx using kotlin

 fun showSnackBar(message: String) {
        mContent?.let {
            val snackbar = Snackbar.make(it, message, Snackbar.LENGTH_LONG)
            val snackbarView = snackbar.view
            val tv = snackbarView.findViewById<TextView>(R.id.snackbar_text)
            tv.setTextColor(Color.WHITE) //change the color of text
            tv.maxLines = 3 //specify the limit of text line
            snackbar.duration = BaseTransientBottomBar.LENGTH_SHORT //specify the duraction of text message
            snackbar.show()
        }
    }

You need initialize mContent inside onViewCreated method like below

var mContent: View? = null
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        mContent = view
    }

Just to save your precious development time, here is the static method I am using:

public static void snack(View view, String message) {
    if (!TextUtils.isEmpty(message)) {
        Snackbar snackbar = Snackbar.make(view, message, Snackbar.LENGTH_SHORT);
        snackbar.getView().setBackgroundColor(Color.YELLOW);
        TextView tv =  snackbar.getView().findViewById(android.support.design.R.id.snackbar_text); //snackbar_text
        tv.setTextColor(Color.BLACK);
        snackbar.show();
    }
}

This is how it looks:

I also noticed the same problem. Thanks to the answers here I've created a small class, which can help to solve this problem in more easily, just by replacing this:

Snackbar.make(view, "Error", Snackbar.LENGTH_LONG).show();

with this:

Snackbar2.make(view, "Error", Snackbar.LENGTH_LONG).show();

Here is my class:

public class Snackbar2 {
static public Snackbar make(View view, int resid, int duration){
    Snackbar result = Snackbar.make(view, resid, duration);
    process(result);
    return result;
}
static public Snackbar make(View view, String text, int duration){
    Snackbar result = Snackbar.make(view, text, duration);
    process(result);
    return result;
}
static private void process(Snackbar snackbar){
    try {
        View view1= snackbar.getView();

        TextView tv = (TextView) view1.findViewById(android.support.design.R.id.snackbar_text);
        tv.setTextColor(Color.WHITE);

    }catch (Exception ex)
    {
        //inform about error
        ex.printStackTrace();
    }
}

}

One approach is to use spans:

final ForegroundColorSpan whiteSpan = new ForegroundColorSpan(ContextCompat.getColor(this, android.R.color.white));
SpannableStringBuilder snackbarText = new SpannableStringBuilder("Hello, I'm white!");
snackbarText.setSpan(whiteSpan, 0, snackbarText.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE);

Snackbar.make(view, snackbarText, Snackbar.LENGTH_LONG)
                .show();

With spans you can also add several colors and styles inside one Snackbar. Here's a nice guide:

Answer 5

If you decide to use the dirty and hacky solution with finding TextView in Snackbar by id and you already migrated to androidx, then here's the code:

val textViewId = com.google.android.material.R.id.snackbar_text
val snackbar = Snackbar.make(view, "Text", Snackbar.LENGTH_SHORT)
val textView = snackbar.view.findViewById(textViewId) as TextView
textView.setTextColor(Color.WHITE)

Answer 6

Hacking on android.support.design.R.id.snackbar_text is fragile, a better or less hacky way to do that will be:

String snackText = getResources().getString(YOUR_RESOURCE_ID);
SpannableStringBuilder ssb = new SpannableStringBuilder()
    .append(snackText);
ssb.setSpan(
    new ForegroundColorSpan(Color.WHITE),
    0,
    snackText.length(),
    Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Snackbar.make(
        getView(),
        ssb,
        Snackbar.LENGTH_SHORT)
        .show();
