android - 重新创建 Activity 时出现生命周期异常

Question

在更改我的应用程序中的语言设置后，我试图重新创建 fragment 和 Activity ，但是 getActivity().recreate();部分正在犯我无法理解的错误。错误是:

E/ActivityInjector: get life cycle exception

当我尝试重新创建 Activity 时发生错误。这是我的 SettingsActivity.java 中的代码:

public class SettingsActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.settings_activity);
        getSupportFragmentManager().beginTransaction().replace(R.id.settings, new SettingsFragment()).commit();
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.setDisplayHomeAsUpEnabled(true);
        }

    }

    public static class SettingsFragment extends PreferenceFragmentCompat {
        ListPreference languages;

        @Override
        public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
            setPreferencesFromResource(R.xml.root_preferences, rootKey);

        }

        @Override
        public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
            languages = getPreferenceManager().findPreference("language");
            languages.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
                @Override
                public boolean onPreferenceChange(Preference preference, Object newValue) {
                    boolean anyChanges=false;
                    if (newValue.toString().equals("turkish")) {
                        LocaleHelper.setLocale(getContext(),"tr-rTR");
                        anyChanges = true;
                    }
                    if (newValue.toString().equals("english")){
                        LocaleHelper.setLocale(getContext(),"en");
                        anyChanges = true;
                    }
                    if (anyChanges){
                        getActivity().recreate();
                    }
                    return true;
                }
            }
            );

            return super.onCreateView(inflater, container, savedInstanceState);
        }
    }

我也有同样的问题，我调查的结果是这样的:这是小米MIUI的一个bug，所以我打赌你正在使用这个ROM(和我一样)，并且出现错误。
我相信我们对此无能为力。
重现步骤
重现错误非常容易。我们只需要创建一个新的 Android Studio 项目，在 Activity 的布局中添加一个按钮，然后在单击按钮时重新创建()该 Activity。
MainActivity.java:

package com.example;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button b = findViewById(R.id.button);
        b.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                recreate();
            }
        });
    }
}

Activity 主.xml:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity">

    <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Hello World!"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

单击 Galaxy Nexus Emulator (API 28, Android 9) 上的按钮会在 Logcat 中提供以下输出:

2021-03-16 05:47:34.981 5927-6028/com.example D/EGL_emulation: eglMakeCurrent: 0xe3a05120: ver 2 0 (tinfo 0xe3a03290)

单击我的第一个真实设备 - 三星 Galaxy S3(API 25，Android 7.1.2，LineageOS 14.1)上的按钮 - 没有输出。
而另一款物理设备——小米红米 7(API 29、Android 10、MIUI Global 11.0.1)在每次按下按钮和 Activity 时都会提供此功能:

因此，当我们重新创建 Activity 时，错误:

E/ActivityInjector: get life cycle exception

显然来自 MIUI/小米(至少在这个实验中)。
