ANDROID - BroadcastReceiver和ImageView

Question

我正在学习Android，我正在试图制作和应用程序，当我旋转手机时改变imageView中的图像，我试图获得广播接收器的价值，我想知道如何做到这一点，这里是代码，对不起，如果它的代码很多，但我不知道我在哪里缺少

主要活动：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

BroadcastReceiver miReceptor;
IntentFilter intentFilter;
Intent intent;
Context context;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    miReceptor = new Receptor();
    intentFilter = new IntentFilter("android.intent.action.CONFIGURATION_CHANGED");

}

@Override
public void onStart(){
    super.onStart();

    miReceptor.onReceive(context, intent);

    registerReceiver(miReceptor,intentFilter);


}

}

布局：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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"
android:background="@android:color/black"
tools:context="com.example.gaboc.covonesrevenge.MainActivity">

<ImageView
    android:id="@+id/puerta"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.814"
    app:srcCompat="@drawable/puerta_cerrada01" />

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:srcCompat="@drawable/covone_revenge" />
  </android.support.constraint.ConstraintLayout>

广播接收器：

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

public class Receptor extends BroadcastReceiver {

private final String ROTATION_CHANGED="android.intent.action.CONFIGURATION_CHANGED";

@Override
public void onReceive(Context context, Intent intent)   {
    if (intent.getAction().equals(ROTATION_CHANGED)){
        Toast.makeText(context, "COVONE'S REVENGE", Toast.LENGTH_LONG).show();
    }
}
}
