android通过broadcastreceiver调用函数

Question

我有一个 broadcastreceiver.class

 public class Myclass extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {

    }
}

我想在我的活动中调用广播接收器中的函数。请用一些代码告诉我如何在此处制作这是我的活动

public class MainActivity extends AppCompatActivity {
    Context context = this;
    private AudioManager myAudioManager;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        public void myfunction()
        {
        final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {

                PackageManager p = getPackageManager();
                ComponentName componentName = new ComponentName(getApplicationContext(),com.example.faisal.wifiprofile.MainActivity.class);
                p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
                handler.postDelayed(this, 100000);
            }
        }, 100000);
        }
    }
}

这是函数名 myfunction 我想在广播接收器中调用这个函数请告诉我好的解决方案或编辑我的代码提前谢谢

这应该可行：

public class Myclass extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
   MainActivity.myfunction();
}

}

public class MainActivity extends AppCompatActivity {
Context context = this;
private AudioManager myAudioManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

    public static void myfunction()
    {
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {

            PackageManager p = getPackageManager();
            ComponentName componentName = new ComponentName(getApplicationContext(),com.example.faisal.wifiprofile.MainActivity.class);
            p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
            handler.postDelayed(this, 100000);
        }
    }, 100000);
    }

}
