Android Snackbar TextAlignment 居中

Question

如何将 Snackbar 文本对齐方式更改为居中？下面的代码不起作用

Snackbar snack = Snackbar.make(findViewById(android.R.id.content), intent.getStringExtra(KEY_ERROR_MESSAGE), Snackbar.LENGTH_LONG);
View view = snack.getView();
TextView tv = (TextView) view.findViewById(android.support.design.R.id.snackbar_text);
tv.setTextColor(ContextCompat.getColor(LoginActivity.this, R.color.red_EC1C24));
tv.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
snack.show();

Answer 1

tv.setGravity(Gravity.CENTER_HORIZONTAL);

编辑

Snackbar 的外观在 Support 库 v23 中已更改，因此现在正确答案是:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
    tv.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
} else {
    tv.setGravity(Gravity.CENTER_HORIZONTAL);
}
