如何获得圆面包

您可以创建自定义视图类，然后对该自定义视图进行充气并像这样使用它

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast,
                               (ViewGroup) findViewById(R.id.your_layout_name));

TextView text = (TextView) layout.findViewById(R.id.your_textview_id);
text.setText("Row Inserted.");

Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();
