推荐答案

首先，你需要存储在共享preferences数据，然后让他们到广播接收器。

First you need to store data in SharedPreferences and then get them into broadcast receiver.

您可以在清单文件中使用code如下：

You can use the code below in manifest file :

<receiver android:name=".YourReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

在code您可以使用：

and in code you can use :

public class YourReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
        {
            //updateWidget();
            SharedPreferences prfs = context.getSharedPreferences("defaul", 0);
            boolean bb=prfs.getBoolean("eer",false);
            alarm=context.getSharedPreferences("def", 0).getString("alarm_time","");
        }
    }
}
