闹钟闹不醒的可以自己去调整下，这个最是最基本的

mainactivity

public class mainactivity extends appcompatactivity {

  private alarmmanager alarmmanager;
  private pendingintent pendingintent;

  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.activity_main);
    //获取闹钟管理者
    alarmmanager = (alarmmanager) getsystemservice(context.alarm_service);


  }

  public void setalarmone(view view) {
    //获取当前系统时间
    calendar calendar = calendar.getinstance();
    int huor = calendar.get(calendar.hour_of_day);
    int minute = calendar.get(calendar.minute);


    //1 弹出时间对话框
    timepickerdialog timepickerdialog = new timepickerdialog(this, new timepickerdialog.ontimesetlistener() {

      @override
      public void ontimeset(timepicker view, int i, int i1) {
        calendar c = calendar.getinstance();
        c.set(calendar.hour_of_day, i);
        c.set(calendar.minute, i1);
        //2确定好选择的时间
        //3设置闹钟
        //4当时间一到，将执行的响应
        intent intent=new intent();
        intent.setaction("com.zking.risk_android_alarn_notification.ring");
        pendingintent = pendingintent.getbroadcast(mainactivity.this,0x101,intent,0);
        alarmmanager.set(alarmmanager.rtc_wakeup,c.gettimeinmillis(), pendingintent);
      }
    }, huor, minute, true);
    timepickerdialog.show();
  }

  public void setalarmcycle(view view) {
    //获取当前系统时间
    calendar calendar=calendar.getinstance();
    int hour=calendar.get(calendar.hour_of_day);
    int minute=calendar.get(calendar.minute);

    //01.弹出时间对话框
    timepickerdialog timepickerdialog=new timepickerdialog(this, new timepickerdialog.ontimesetlistener() {
      @override
      public void ontimeset(timepicker timepicker, int i, int i1) {
        calendar c=calendar.getinstance();
        c.set(calendar.hour_of_day,i);
        c.set(calendar.minute,i1);
        //02.确定好选择的时间
        //03.设置闹钟

        //04.当之间一到，将执行的响应
        intent intent=new intent();
        intent.setaction("com.zking.risk_android_alarn_notification.ring");
        pendingintent = pendingintent.getbroadcast(mainactivity.this,0x102,intent,0);
        alarmmanager.setrepeating(alarmmanager.rtc_wakeup,c.gettimeinmillis(),5000, pendingintent);
      }
    },hour,minute,true);
    timepickerdialog.show();

  }

  public void cancelalarmcycle(view view){
    alarmmanager.cancel(pendingintent);
  }


}

ringactivity

public class ringactivity extends appcompatactivity {

  private mediaplayer mediaplayer;

  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.activity_ring);

    //播放音乐
    mediaplayer = mediaplayer.create(this, r.raw.rooster);
    mediaplayer.start();
  }

  public void close(view view) {
    mediaplayer.stop();
    finish();
  }
}

ringreceived

public class ringreceived extends broadcastreceiver{
  @override
  public void onreceive(context context, intent intent) {
    if("com.zking.risk_android_alarn_notification.ring".equals(intent.getaction())){
      log.i("test","收到广播了");

      //跳转到activity
      intent intent1=new intent(context,ringactivity.class);
      //给intent设置标志位flag
      intent1.setflags(intent.flag_activity_new_task);
      //intent的组成部分：componementname extra action data categlay(分组) flag
      context.startactivity(intent1);
    }
  }
}

activity_main

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main"
  android:layout_width="match_parent" android:layout_height="match_parent"
  android:paddingbottom="@dimen/activity_vertical_margin"

  android:paddingright="@dimen/activity_horizontal_margin"

  android:orientation="vertical"
  tools:context="com.zking.risk_android_alarn_notification.mainactivity">

  <button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="设置闹钟（一次）"
    android:onclick="setalarmone"
    />
  <button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="设置闹钟（周期）"
    android:onclick="setalarmcycle"
    />
<button
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:text="取消周期闹钟"
  android:onclick="cancelalarmcycle"
  />

</linearlayout>

actiity_ring

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:id="@+id/activity_ring"
  android:layout_width="match_parent"

    />

  <timepicker

    android:layout_height="378dp"
    android:id="@+id/timepicker"
    android:layout_weight="0.30" />

<button
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:text="关闭"
  android:onclick="close"
  />


</linearlayout>

最后的清单配置

 <activity android:name=".ringactivity"></activity>

    <receiver android:name=".ringreceived">
      <intent-filter>
        <action android:name="com.zking.risk_android_alarn_notification.ring"></action>
      </intent-filter>

    </receiver>
