和代码：

TextView textViewSnack = (TextView) findViewById(android.support.design.R.id.snackbar_text);   

textViewSnack.setTextColor(ContextCompat.getColor(PlaceActivity.this, R.color.colorPrimaryDark));

Answer 1

试试这个，

您需要通过 view 的SnackBar来查找 textView 的SnackBar。

Snackbar snackbar = Snackbar.make(
                    coordinatorLayout,
                    "Snackbar: floatingActionButton1 (normal) clicked",
                    Snackbar.LENGTH_LONG);
snackbar.setActionTextColor(Color.RED); //to change the color of action text
View snackbarView = snackbar.getView();
snackbarView.setBackgroundColor(Color.WHITE);
TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(ContextCompat.getColor(PlaceActivity.this, R.color.colorPrimaryDark));

当我尝试更改SnackBar TextView应用程序崩溃的颜色时
