重新创建活动时获取生命周期异常 [英] Getting Lifecycle Exception While Recreating The Activity

问题描述

我试图在更改应用程序中的语言设置后重新创建片段和活动，但是 getActivity().recreate(); 部分正在产生我无法理解的错误.错误是:

I am trying to recreate the fragment and the activity after changing the language setting in my app but getActivity().recreate(); part is making errors that I couldn't understand why. The error is :

E/ActivityInjector: get life cycle exception

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

The error occurs when I try to recreate the activity. Here's the code in my SettingsActivity.java:

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);
        }
    }

推荐答案

我遇到了同样的问题，对这个问题的调查结果是:thig是小米的MIUI中的错误，所以我敢打赌你是使用此ROM(像我一样)，就会发生错误.

I have the same problem, and the result of my investigation of the problem is this: thig is a bug in MIUI from Xiaomi, so I bet you're using this ROM (like me), and the error occurs.

我相信我们对此无能为力.

要复制的步骤

很容易重现该错误.我们只需要创建一个新的Android Studio项目，在活动的布局中添加一个按钮，然后在单击按钮时重新创建活动即可.

It's very easy to reproduce the bug. We simply have to create a new Android Studio project, add a button to the activity's layout, and we recreate() the activity on the button click.

MainActivity.java:

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_main.xml:

activity_main.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>

点击Galaxy Nexus模拟器(API 28，Android 9)上的按钮，即可在Logcat中获得以下输出:

Clicking the button on Galaxy Nexus Emulator (API 28, Android 9) gives this output in Logcat:

在我的第一台真实设备上单击按钮-Samsung Galaxy S3(API 25，Android 7.1.2，LineageOS 14.1)-没有输出.

Clicking on the button on my first real device - Samsung Galaxy S3 (API 25, Android 7.1.2, LineageOS 14.1) - gives no output.

另一种物理设备-小米Redmi 7(API 29，Android 10，MIUI Global 11.0.1)在每次按下按钮和进行活动娱乐时都会提供此功能:

Whereas another physical device - Xiaomi Redmi 7 (API 29, Android 10, MIUI Global 11.0.1) gives this on every button press and activity recreation:

因此，当我们重新创建活动时，会出现错误:

So when we recreate the activity, the error:

E/ActivityInjector: get life cycle exception

显然来自MIUI/小米(至少在此实验中).

clearly comes from MIUI/Xiaomi (at least in this experiment).
