React Native - 当前 Activity 的类不正确，预期为 AppCompatActivity，收到了 MyActivity

Question

当我收到无声通知时，我需要调用反应本机屏幕，目前我正在试验电话状态，我使用 PhoneStateListenr 类来触发名为 MyActivity 的第二个活动，并在其中运行 React Native 代码。

运行 MyActivity 类时出现以下错误，即指出当前活动属于不正确的类，

java.lang.IllegalStateException: Current Activity is of incorrect class, expected AppCompatActivity, received MyActivity

MyActivity 在电话状态下触发，

package com.apartmentapp;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class PhoneStateListener extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            final Context ctx;
            ctx = context;

            final Intent intnt = new Intent(context, MyActivity.class);

            intnt.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intnt.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

            intnt.putExtra("phone_no", "9876543210");
            intnt.putExtra("contact_name", "Test User");

            intnt.putExtra("id", "1234");

            ctx.startActivity(intnt);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

下面是我的ActivityClass

package com.apartmentapp;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;

import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import androidx.fragment.app.Fragment;

import com.facebook.hermes.reactexecutor.HermesExecutorFactory;
import com.facebook.react.BuildConfig;
import com.facebook.react.PackageList;
import com.facebook.react.ReactInstanceManager;
import com.facebook.react.ReactPackage;
import com.facebook.react.ReactRootView;
import com.facebook.react.common.LifecycleState;
import com.facebook.react.modules.core.DefaultHardwareBackBtnHandler;
import com.facebook.soloader.SoLoader;

import java.util.List;

public class MyActivity extends Activity implements DefaultHardwareBackBtnHandler {
    private Window wind;
    private ReactRootView mReactRootView;
    private ReactInstanceManager mReactInstanceManager;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.setFinishOnTouchOutside(true);
        super.onCreate(savedInstanceState);
        SoLoader.init(this, false);

        mReactRootView = new ReactRootView(this);
        List<ReactPackage> packages = new PackageList(getApplication()).getPackages();

        mReactInstanceManager = ReactInstanceManager.builder()
                .setApplication(getApplication())
                .setCurrentActivity(this)
                .setBundleAssetName("index.android.bundle")
                .setJSMainModulePath("index")
                .addPackages(packages)
                .setUseDeveloperSupport(BuildConfig.DEBUG)
                .setInitialLifecycleState(LifecycleState.RESUMED)
                .setJavaScriptExecutorFactory(new HermesExecutorFactory())
                .build();

        mReactRootView.startReactApplication(mReactInstanceManager, "AlertPopupFragment", null);

        setContentView(mReactRootView);
        setContentView(R.layout.dialog);

        FrameLayout alertPopUpFragment = findViewById(R.id.alertPopUpFragment);

        alertPopUpFragment.addView(mReactRootView);
    }

    private Bundle getLaunchOptions(String message) {
        Bundle initialProperties = new Bundle();
        initialProperties.putString("message", message);
        return initialProperties;
    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();

        wind = this.getWindow();
        wind.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
        wind.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
        wind.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
        wind.addFlags(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
        wind.addFlags(WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY);
    }

    @Override
    public void invokeDefaultOnBackPressed() {

    }
}

我也尝试通过将MyActivity设置为MainActivity来解决它，

这里是 Android Manifest 文件中定义的 MyActivity

<activity
            android:name=".MyActivity"
            android:noHistory="true"
            android:taskAffinity=".MyActivity"
            android:theme="@style/MyActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

请提供解决方案

Answer 1

错误很清楚问题是什么以及如何解决：

Current Activity is of incorrect class, expected AppCompatActivity, received MyActivity

目前你的定义是

MyActivity extends Activity

，但是react Native似乎需要将其更改为

MyActivity extends AppCompatActivity

。

AppCompatActivity

的完整类名很可能是androidx.appcompat.app.AppCompatActivity。因此，您必须在 Java 文件的开头添加导入：

import androidx.appcompat.app.AppCompatActivity;
