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);
}
}
}
