更改快餐栏中操作按钮的背景颜色

Question

how can I change the background color of action button in snackbar or make it dissapear (grey background)?

i use this code:

        Snackbar mysnack = Snackbar.make(main_layout, getResources().getString(R.string.snack_1), 5000);
            View view = mysnack.getView();
            TextView tv = (TextView) view.findViewById(android.support.design.R.id.snackbar_text);
            tv.setTextColor(getResources().getColor(R.color.text_light));
            mysnack.setActionTextColor(getResources().getColor(R.color.text_light));
            mysnack.setAction("RATE", new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    Uri uri = Uri.parse(getResources().getString(R.string.snack_url));
                    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                    startActivity(intent);
                }
            });
            TypedValue typedValue = new TypedValue();
            getTheme().resolveAttribute(R.attr.colorPrimaryDark, typedValue, true);
            final int color = typedValue.data;
            mysnack.getView().setBackgroundColor(color);
            mysnack.show();

and my question is not duplicate. I ask for BACKGROUND color and not the text color. First we read, then we understand, then we think and then we decide to write that someone's question is a duplicate.

Answer 1

I had the same issue. Found out it can be a bug of new Material theme. Main theme of my application is:

<style name="AppTheme" parent="@style/Theme.MaterialComponents.Light.NoActionBar">

If I change it to AppCompat snack button's gray background dissapears. Eventually I found that it was because of the bug.

My solution was (I needed Material theme and can not simply change it to AppCompat): Found button id for the snack. It is "@id/snackbar_action":

val snackButton: Button = yourSnackbar.getView().findViewById(R.id.snackbar_action)

and then changed it background to null:

snackButton.setBackground(null)

This code snippet may help you out:

Snackbar snackbar = Snackbar.make(
                    coordinatorLayout,
                    "Snackbar: floatingActionButton1 (normal) clicked",
                    Snackbar.LENGTH_LONG);
            snackbar.setActionTextColor(Color.RED);
            View snackbarView = snackbar.getView();
            snackbarView.setBackgroundColor(Color.WHITE);
            TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
            textView.setTextColor(Color.BLUE);

对于 Xamarin，你可以试试这个

 snackbar.View.SetBackgroundColor(Android.Graphics.Color.ParseColor("#32CD32"));

If you want to change action button background color..

View sbView = snackbar.getView();
Button button=
(Button) sbView.findViewById(com.google.android.material.R.id.snackbar_action);
button.setBackgroundColor(getResources().getColor(R.color.white));

If you want to change action button text color..

snackbar.setActionTextColor(getResources().getColor(R.color.colorAccent));

With the Material Components Library you can use the snackbarButtonStyle attribute in your app theme.
Something like:

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
    <!-- Style to use for action button within a Snackbar in this theme. -->
    <item name="snackbarButtonStyle">@style/Widget.App.Button.TextButton.Snackbar</item>
</style>


<style name="Widget.App.Button.TextButton.Snackbar" parent="Widget.MaterialComponents.Button.TextButton.Snackbar">
    <item name="backgroundTint">@color/colorSecondary</item>
</style>
