这是代码:
public class BillingService extends Service implements ServiceConnection {
...
@Override
public void onStart(Intent intent, int startId) {
handleCommand(intent, startId); // line 361
}
/**
* The {@link BillingReceiver} sends messages to this service using intents.
* Each intent has an action and some extra arguments specific to that action.
* @param intent the intent containing one of the supported actions
* @param startId an identifier for the invocation instance of this service
*/
public void handleCommand(Intent intent, int startId) …我TextSwitcher的每个记录ListView应显示第一个值(text1),然后显示另一个值(text2),然后再显示第一个值,依此类推.只有当text2不为空时才会发生.否则,应始终显示text1(不进行任何更改和动画).
我创建了Runnable(),它改变了布尔变量(time2)然后调用items.notifyDataSetChanged().它按预期工作,结果setViewValue()我ListView被称为.
这是代码:
items.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
@Override
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
int viewId = view.getId();
switch(viewId) {
case R.id.timetext:
TextSwitcher itemTime = (TextSwitcher) view;
if (itemTime.getChildCount() != 2) {
itemTime.removeAllViews();
itemTime.setFactory(new ViewSwitcher.ViewFactory() {
@Override
public View makeView() {
TextView t = new TextView(MyActivity.this);
t.setTextSize(18);
t.setTypeface(null, Typeface.BOLD);
t.setTextColor(Color.WHITE);
return t;
}
});
itemTime.setAnimateFirstView(true);
itemTime.setInAnimation(AnimationUtils.loadAnimation(MyActivity.this, …我有两个String变量 - time1和time2.两者都包含格式为HH:MM的值.我该怎么检查:
time1和之内
time2?time1 会在最近的一小时内发生吗？UPD.
我已经实现了以下转换time1为Date格式.但它使用折旧方法:
Date clTime1 = new Date();
SimpleDateFormat timeParser = new SimpleDateFormat("HH:mm", Locale.US);
try {
clTime1 = timeParser.parse(time1);
} catch (ParseException e) {
}
Calendar now = Calendar.getInstance();
clTime1.setYear(now.get(Calendar.YEAR) - 1900);
clTime1.setMonth(now.get(Calendar.MONTH));
clTime1.setDate(now.get(Calendar.DAY_OF_MONTH));
System.out.println(clTime1.toString());
我有以下代码:
@Override
protected void onPostExecute(Void arg0) {
...
Toast.makeText(getBaseContext(), getBaseContext().getResources().getString(R.string.toast_sync_completed), Toast.LENGTH_SHORT).show();
}
它失败了(FC).如果通过"Test string"而不是getResources().getString(R.string.toast_sync_completed),那么它可以正常工作.我究竟做错了什么？
我需要验证我的应用内结算方式是如何运作的.想用测试帐户测试一下.
如果我使用测试帐户购买我的应用内商品,是否需要付费？
我想在图像中添加俄语文本.我在Windows机器上使用PIL 1.1.7和Python 2.7.由于PIL编译时没有libfreetype库,我在开发服务器上使用以下代码:
font_text = ImageFont.load('helvR24.pil')
draw.text((0, 0), '????? ?? ???????', font=font_text)
(helvR24.pil摘自http://effbot.org/media/downloads/pilfonts.zip)
在生产环境中,我执行以下操作:
font_text = ImageFont.truetype('HelveticaRegular.ttf', 24, encoding="utf-8")
draw.text((0, 0), '????? ?? ???????', font=font_text)
(试图使用unic,cp-1251而不是utf-8)
在这两种情况下,它都不显示俄语字符(而是显示"正方形"或虚拟字符).我认为它不适用于开发环境,因为大多数可能helvR24.pil不包含俄语字符(不知道如何检查它).但HelveticaRegular.ttf肯定有.我还检查过我的.py文件有геа-8编码.即使使用默认字体,它也不会显示俄语字符:
draw.text((0, 0), '????? ?? ???????', font=ImageFont.load_default())
我还应该尝试/验证什么？我通过/sf/answers/1311065871/查看 - 它没有帮助.

我想了解可以从Google AnalyticsAPI请求上周(周一至周日)数据的最早时间:
response = service.data().ga().get(
ids='ga:78212345',
start_date='2014-03-31',
end_date='2014-04-06',
metrics='ga:visitors').execute()
我将使用GAE cron请求数据,它使用UTC.如果我定义every monday 00:01,星期日将在Google Analytics时区完成吗？
UPD.那老讨论说,谷歌Analytics(分析)API使用的时区的轮廓.我使用服务帐户(myappid@appspot.gserviceaccount.com)来访问API.在这种情况下使用哪个时区设置？
