推荐答案

这是因为你总是使用相同的意向。如果你想有一个以上的报警预定，您需要修改你的意图。例如，您可以定义一个整数 ID 和一个增加它为每一个新的报警。然后你可以使用下面的code转让本 ID 到意图。

This is because you always use the same Intent. If you want to have more than one alarm scheduled, you need to modify your intent. For instance you can define an integer id and increase it for every new alarm by one. Then you can use the code below to assign this id to the intent.

public class AlarmReceiver extends Activity {

    private int id = 0;

    @Override
    public void onClick(View v) {

        Intent intent=new Intent(SetAlarm.this,AlarmReceiver.class);
        intent.setData(Uri.parse("alarm:" + (id++)));

        ... rest of your code here
    }

}

如果你想取消（）报警，你需要使用意图用的正是这种 ID 。

If you want to cancel() alarm, you need to use intent with exactly this id.
