我想知道如果我可以用or在switch-caseJava中？
例
switch (value)
{
case 0:
do();
break;
case 2 OR 3
do2();
break;
}
我有EditText,我希望它以Spinner的相同主题显示,带有背景和箭头因为我已经制作了这个EditTextClickable并且它打开了一个自定义弹出窗口
我在我的应用程序中经常收到以下 ANR
Input dispatching timed out (Waiting to send key event because the focused window has not finished processing all of the input events that were previously delivered to it. Outbound queue length: 0. Wait queue length: 1.)
日志显示onActivityStopped方法中存在问题
这是我在此方法中添加的代码
try {
boolean foreground = new ForegroundCheckTask().execute(getApplicationContext()).get();
if(!foreground) {
AdServerManager.getInstance().incrementImpression(activity, ForSaleDataManager.getInstance().getBannerImpression(),
ForSaleDataManager.getInstance().getOfferImpression(), new View.OnClickListener() {
@Override
public void onClick(View v) {
ForSaleDataManager.getInstance().clearOfferImpression();
ForSaleDataManager.getInstance().clearBannerImpression();
}
});
String lastOffers = TextUtils.join("," , ForSaleDataManager.getInstance().getVisitedOffersIds());
//Appboy.getInstance(activity).getCurrentUser().setCustomUserAttribute(AppBoyAttributeName.LAST_TEN_OFFER_IDS.getValue() , lastOffers);
ForSaleDataManager.getInstance().clearVisitedOffersIds();
String lastCategories = …我有以下结构:
public enum MyTypes
{
Type1 = 1,
Type2 = 2,
Type3 = 3
}
public abstract class class1
{
int id;
string name;
MyType type;
}
public class class2 : class1
{
}
public class class3 : class1
{
}
public class class4 : class1
{
}
现在我要做的是创建一个泛型方法,我想给它类型对象说类3,它将从类3创建对象并定义它的变量并返回它以便能够将它添加到列表中class1的
像那样
private class1 myFunction (MyType t , int id , string name)
{
T obj = new T();
obj.type = t ;
obj.id = id ;
obj.name = name;
return obj; …我正在开发android应用程序
对于按钮的每个状态,我有不同的背景可绘制和文本颜色(按下,正常)
我创建了statelistdrawable对象以便能够添加背景drawable,但我现在的问题是如何设置文本颜色
有人可以帮忙吗？
