android告警无法启动告警活动

Question

我是新手的android编程，并试图使这个简单的警报应用程序。我写了我的代码，它没有任何错误的编译。应用程序在模拟器中运行，即主活动询问日期和时间，但当我单击确认按钮时，它会显示消息-“不幸的是，Timer1已停止工作”。

我的主要活动的代码如下：

public void onClick(View v) {
    EditText date = (EditText) findViewById(R.id.editDate);
    EditText month = (EditText) findViewById(R.id.editMonth);
    EditText hour = (EditText) findViewById(R.id.editHour);
    EditText min = (EditText) findViewById(R.id.editMin);
    int dt = Integer.parseInt(date.getText().toString());
    int mon = Integer.parseInt(month.getText().toString());
    int hr = Integer.parseInt(hour.getText().toString());
    int mnt = Integer.parseInt(min.getText().toString());
    Intent myIntent = new Intent(MainActivity.this, AlarmActivity.class);
    pendingIntent = PendingIntent.getService(MainActivity.this, 0, myIntent, 0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.DATE, dt);
    calendar.set(Calendar.MONTH, mon);
    calendar.set(Calendar.HOUR, hr);
    calendar.set(Calendar.MINUTE, mnt);
    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}

我不明白logcat中的所有错误是什么意思，所以我将它们张贴出来：

Answer 1

  int dt = Integer.parseInt(date.getText().toString());
                int mon = Integer.parseInt(month.getText().toString());
                int hr = Integer.parseInt(hour.getText().toString());
                int mnt = Integer.parseInt(min.getText().toString());

其中一个是不能解析为整数的。

查看哪一个的方法：

首先这样写出来：

String date = date.getText().toString();

对所有4个执行类似的操作

and then Log.i("YOURACTIVITNAME", "date:"+date+" hour"+.....);

或者，您可以简单地插入断点，并对其进行调试，而不是Log.i。看看哪一个会犯错。

在tostring后面使用.trim()来删除空格也是很好的做法。
