解决方案

我能够复制您的问题，并找出它为什么失败。基本上，说你正在测试的12:25像我，然后用12 Calendar.HOUR 和做c.get（Calendar.HOUR_OF_DAY）的返回0。

要更改，只需使用：

 日历C = Calendar.getInstance（）;
c.setTimeInMillis（System.currentTimeMillis的（））;
c.set（Calendar.HOUR_OF_DAY，hourOfDay）;
c.set（Calendar.MINUTE，分钟）;
c.set（Calendar.SECOND，0）;

即。除去透明，并设置 HOUR_OF_DAY 而不是一小时

In my alarm application, I take time from time picker and set it in alarm manager. But the time which I set in the time picker was not set properly in alarm manager. So the alarm is not activated at the specified time. I have included my code below. Could anybody help me out?

layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"

<Button
    android:id="@+id/btn"
    android:text="Alerm"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />
</LinearLayout>

MainActivity.java

public class MainActivity extends Activity {
    private Button btn = null;
    private AlarmManager alarmManager = null;
    Calendar cal = Calendar.getInstance();
    static final int DIALOG_TIME = 0;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        btn = (Button) findViewById(R.id.btn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showDialog(DIALOG_TIME);

    }

解决方案

I was able to replicate your problem and find why it was failing. Basically, say you were testing at "12:25" like i was, then using Calendar.HOUR of 12 and doing c.get(Calendar.HOUR_OF_DAY) was returning 0.

To change, simply use:

Calendar c = Calendar.getInstance();
c.setTimeInMillis(System.currentTimeMillis());
c.set(Calendar.HOUR_OF_DAY, hourOfDay);
c.set(Calendar.MINUTE, minute);
c.set(Calendar.SECOND, 0);

i.e. remove the clear, and set HOUR_OF_DAY instead of HOUR
