Question

我有一个broadcastreceiver.class

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

    }
}

我想在broadcastreceiver中调用函数，这是我的活动。请告诉我一些代码如何在这里做我的活动

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);
        }
    }
}

这里是函数名myfunction我想在broadcastreceiver中调用这个函数请事先告诉我好的解决方案或编辑我的代码

这应该有效：

SELECT m.*,
    CASE 
        WHEN m.fromid = $id THEN m.from_status 
        WHEN m.toid = $id THEN m.to_status
    END as read_status
FROM message m
WHERE
    m.fromid = $id OR m.toid = $id
ORDER BY timestamp DESC;

}

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

}

android通过broadcastreceiver调用函数
