如何将数据从BroadcastReceiver传递到安卓中的Activity

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 获取传递的数据
        String data = intent.getStringExtra("key");
        
        // 在此处处理数据，例如更新UI或执行其他操作
    }
}

public class MyActivity extends AppCompatActivity {
    private MyBroadcastReceiver receiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 创建BroadcastReceiver实例
        receiver = new MyBroadcastReceiver();

        // 注册广播接收器
        IntentFilter filter = new IntentFilter("com.example.MY_ACTION");
        registerReceiver(receiver, filter);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        // 在Activity销毁时取消注册广播接收器
        unregisterReceiver(receiver);
    }
}

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String data = intent.getStringExtra("key");
        
        // 将数据传递给Activity
        Intent activityIntent = new Intent(context, MyActivity.class);
        activityIntent.putExtra("data", data);
        context.startActivity(activityIntent);
    }
}

public class MyActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        // 获取从BroadcastReceiver传递过来的数据
        String data = getIntent().getStringExtra("data");
        
        // 在此处处理数据，例如更新UI或执行其他操作
    }
}
