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。

 package cc.wulian.smarthomev6.support.utils;

 import android.support.annotation.StringRes;
 import android.view.Gravity;
 import android.widget.TextView;
 import android.widget.Toast;

 import cc.wulian.smarthomev6.R;
 import cc.wulian.smarthomev6.main.application.MainApplication;

 /**
  * Created by huxc on 2017/6/15.
  * 统一弹Toast
  */

 public class ToastUtil {
     private static Toast toast;

     public static void show(String text) {
         if (toast == null) {
             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
　　　　　　　　　　//这个地方第二个参数需要为null
             toast.setText(text);
         } else {
             toast.setText(text);
         }
         toast.show();
     }

     public static void show(@StringRes int resId) {
         if (toast == null) {
             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
             toast.setText(resId);
         } else {
             toast.setText(resId);
         }
         toast.show();
     }

     /**
      * 弹出多个toast时, 不会一个一个的弹, 后面一个要显示的内容直接显示在当前的toast上
      */
     public static void single(String msg) {
         if (toast == null) {
             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
             toast.setText(msg);
         } else {
             toast.setText(msg);
         }
         toast.show();
     }

     public static void singleLong(String msg) {
         if (toast == null) {
             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_LONG);
             toast.setText(msg);
         } else {
             toast.setText(msg);
         }
         toast.show();
     }

     /**
      * 多行居中显示
      */
     public static void singleCenter(@StringRes int msg) {
         if (toast == null) {
             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
             toast.setText(msg);
         } else {
             toast.setText(msg);
         }
         ((TextView) toast.getView().findViewById(android.R.id.message)).setGravity(Gravity.CENTER);
         toast.show();
     }

     /**
      * 多行居中显示
      */
     public static void singleCenter(String msg) {
         if (toast == null) {
             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
             toast.setText(msg);
         } else {
             toast.setText(msg);
         }
         ((TextView) toast.getView().findViewById(android.R.id.message)).setGravity(Gravity.CENTER);
         toast.show();
     }

     /**
      * 弹出多个toast时, 不会一个一个的弹, 后面一个要显示的内容直接显示在当前的toast上
      */
     public static void single(@StringRes int msg) {
         if (toast == null) {
             toast = Toast.makeText(MainApplication.getApplication(), null, Toast.LENGTH_SHORT);
             toast.setText(msg);
         } else {
             toast.setText(msg);
         }
         toast.show();
     }
 }

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