真理往往是在少数人手里，而少数人必须服从多数人，到头来真理还是在多数人手里。

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);
        }
    }
}
