我是 android 编程新手，正在尝试制作这个简单的警报应用程序。我编写了我的代码，并且编译时没有错误。该应用程序在模拟器中运行，即主要活动询问日期和时间，但是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，所以我发布它们：

  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());

其中之一不能解析为整数。

看哪一个的方法：

首先这样写出来：

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

对于所有 4 做类似

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

或者，您可以简单地插入一个断点，而不是 Log.i，然后对其进行调试。看看哪一个犯了错误。

在 tostring 之后使用 .trim() 删除空格也可能很好。
