静态吐司

1.静态吐司,好处是吐司之间不用延时

public class ToastUtil {    public static Toast toast;    public static void toast(String text) {        /**         * toast为null的情况         * 1.第一次调用         * 2.toast吐司完成         */        if (toast == null) {            toast = Toast.makeText(MyApplication.getContext(), text, Toast.LENGTH_SHORT);        }        toast.setText(text);        toast.show();    }}

2.在Application中获取上下文

 public class MyApplication extends Application {    private static MyApplication baseApp;    public static Context getContext() {        return baseApp;    }}
