代码如下
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if (isChecked) {
Calendar currentTime = Calendar.getInstance();
//创建一个TimePickerDialog实例，并显示
new TimePickerDialog(MainActivity.this, 0,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
//指定启动AlarmActivity组件
Intent intent = new Intent(MainActivity.this, AlarmActivity.class);
//创建PendingIntent对象
PendingIntent pi = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);
Calendar c = Calendar.getInstance();
c.setTimeInMillis(System.currentTimeMillis());
c.set(Calendar.HOUR, hourOfDay);
c.set(Calendar.MINUTE, minute);
alarmManager.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pi);
Toast.makeText(MainActivity.this, "设置闹钟成功", Toast.LENGTH_SHORT).show();
}
}, currentTime.get(Calendar.HOUR_OF_DAY), currentTime.get(Calendar.MINUTE), false).show();
}
else {
}
}
AlarmActivity.java:
package com.example.financesetting;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.media.MediaPlayer;
import android.os.Bundle;
public class AlarmActivity extends Activity {
MediaPlayer alarmMusic;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_alarm);
alarmMusic = MediaPlayer.create(this, R.raw.sqbm);
alarmMusic.setLooping(true);
alarmMusic.start();
new AlertDialog.Builder(AlarmActivity.this).setTitle("闹钟")
.setMessage("该记账啦！")
.setPositiveButton("停止", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// 停止音乐
alarmMusic.stop();
AlarmActivity.this.finish();
}
}).show();
}
}
请大神帮忙解答
生命周期好好看看，在哪里写调用
