小米手机Toast显示带应用名称问题解决方法

近期为了适配刘海屏，向公司申购了一步小米8的手机，然后测试人员那边测出来一堆适配的问题，其中有一个每一个Toast会显示app的名称+显示的内容，然后网上查找了一下解决方法记录一下，顺便封装了ToastUtil方便调用。

  3 import android.support.annotation.StringRes;
  4 import android.view.Gravity;
  5 import android.widget.TextView;
  6 import android.widget.Toast;

 17     private static Toast toast;
 18 
 19     public static void show(String text) {
 20         if (toast == null) {
 21             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
　　　　　　　　　　//这个地方第二个参数需要为null
 22             toast.setText(text);
 23         } else {
 24             toast.setText(text);
 25         }
 26         toast.show();
 27     }

 29     public static void show(@StringRes int resId) {
 30         if (toast == null) {
 31             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);

 35         }
 36         toast.show();
 37     }

 46         } else {
 47             toast.setText(msg);
 48         }
 49         toast.show();
 50     }
 51 
 52     public static void singleLong(String msg) {
 53         if (toast == null) {
 54             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_LONG);
 55             toast.setText(msg);
 56         } else {
 57             toast.setText(msg);
 58         }

 70             toast.setText(msg);
 71         }
 72         ((TextView) toast.getView().findViewById(android.R.id.message)).setGravity(Gravity.CENTER);
 73         toast.show();
 74     }
 75 
 76     /**

 79     public static void singleCenter(String msg) {
 80         if (toast == null) {
 81             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);

 85         }

 90     /**

 93     public static void single(@StringRes int msg) {
 94         if (toast == null) {
 95             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
 96             toast.setText(msg);
 97         } else {
 98             toast.setText(msg);
 99         }
100         toast.show();
101     }
102 }

Toast.makeText()方法的第二个参数传null,然后mtoast.settext(text)重新设置一下。
