toast

I have tried with the below code to compare two times: SimpleDateFormat sdf = new SimpleDateFormat("hh:mm"); Date inTime = sdf.parse("11:00"); Date outTime = sdf.parse("10:00"); if(inTime.compareTo(outTime) > 0){ Toast.makeText(this, "Out time should be greater than In time", Toast.LENGTH_SHORT).show(); } Above code is working fine. But if I give in time as 11:00 and out time as 12:00, I am getting above toast message. I am getting above toast message if I give out time from 12:00 to 12:59. In other cases above code is working fine. Where I am doing wrong. Please help me. Change

1、PendingIntent作用 根据字面意思就知道是延迟的intent，主要用来 在某个事件完成后执行特定的Action 。PendingIntent包含了Intent及Context，所以就算Intent所属程序结束，PendingIntent依然有效，可以在其他程序中使用。 常用在通知栏及短信发送系统中。 PendingIntent一般作为参数传给某个实例，在该实例完成某个操作后自动执行PendingIntent上的Action，也可以通过PendingIntent的send函数手动执行，并可以在send函数中设置OnFinished表示send成功后执行的动作。 2、PendingIntent举例 a. 系统通知栏 NotificationManager nm = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE); int icon = android.R.drawable.stat_notify_chat; long when = System.currentTimeMillis() + 2000 ; Notification n = new Notification(icon, "通知栏demo提醒" , when); n.defaults = Notification

I have a broadcast receiver and I am trying to show a toast message from it, is this possible ? This code doesn't show the toast but it print the log message in the logcat. Is there some idiotic thing I am doing or what is my problem ? @Override public void onReceive(Context context, Intent intent) { Log.v("log", "this is shown"); Toast.makeText(context, "this is not shown" , Toast.LENGTH_LONG); } Call the show() method for the Toast . you forgot to call show() on the Toast .. although i would not recommend creating toasts from BroadcastReceivers.. you might consider using Notifications Use

We've got a Windows Forms Application (vs. WPF) that was originally created for Windows 7. We're carrying the product forward to be used in Windows 8. Is it possible to show Windows 8 Toast Notifications (Windows.UI.Notifications namespace) from this WinForm app, for users running Windows 8? I can't seem to find any examples. Everything I find is a WPF or Windows Store apps—no examples are WinForm apps. It is possible to use toast notification in winform poject under win 8. I create a winform project, add a button, when pressing the button, there will be a toast notification showed in the

效果图： 1、创建menu文件夹，新建main.xml文件 <?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/add" android:title="添加" /> <item android:id="@+id/remove" android:title="删除" /> <item android:id="@+id/share" android:title="分享" /></menu>2、在MainActivity 中 public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final ImageView imageVie = findViewById(R.id.main_img); imageVie.setOnClickListener(new View

什么是内存泄露？ 　　就是该回收的内存由于种种原因没有被回收，还驻留在内存中。 内存泄露有什么影响？ 　　可能一处小小的内存泄露就会导致整个应用卡顿，甚至崩溃。 例子说明：　　 Toast.makeText(MainActivity.this,"Hello",Toast.LENGTH_SHORT).show(); 　　这段代码可能会出现内存泄露。 为什么说可能会造成内存泄露？ 　　如果在Toast消失之前，Toast 持有了当前的 Activity，而此时，用户点击了返回键，导致 Activity 无法被 GC（Garbage Collection垃圾回收） 回收，这个Activity 就引起了内存泄露。 解决方法？ 　　所有和当前 Activity 无关的 Context 都可以传入，避免内存泄露的方法同样使用其他需要传入 Context 的地方。（这句话我表示理解不了）如下 Toast.makeText(getApplicationContext(),"Hello",Toast.LENGTH_SHORT).show(); 　　getApplicationContext()是整个应用的上下文，不会持有某个 Activity 对象。 注意 　　dialog的上下文不能使用getApplicationContext()，程序会崩掉，dialog实例化必须持有 Activity对象。

I'm using this code to send notifications from PowerShell script. PowerShell itself is launched by (persistent) Java application. [Windows.UI.Notifications.ToastNotificationManager, Windows.UI.Notifications, ContentType = WindowsRuntime] > $null [Windows.Data.Xml.Dom.XmlDocument, Windows.Data.Xml.Dom.XmlDocument, ContentType = WindowsRuntime] > $null [Windows.UI.Notifications.ToastNotification, Windows.UI.Notifications, ContentType = WindowsRuntime] > $null $xml = New-Object Windows.Data.Xml.Dom.XmlDocument $template = "<toast><visual><binding template=`"ToastText02`"><text id=`"1`">Title<

3.0之后推荐用actionbar，Menu已经过时但是我们还是了解一下吧， Menu学习 在java语句中添加menu组件 重写onCreateOptionsMenu(Menu menu)方法 @Override public boolean onCreateOptionsMenu(Menu menu) { MenuItem menuItem1 = menu.add(100, 100, 1, "系统菜单"); menuItem1.setIcon(R.drawable.ic_launcher_background); menuItem1.setTitle("菜单一"); MenuItem menuItem2 = menu.add(100, 101, 2, "系统菜单"); menuItem2.setIcon(R.drawable.ic_launcher_background); menuItem2.setTitle("菜单二"); MenuItem menuItem3 = menu.add(100, 102, 3, "系统菜单"); menuItem3.setIcon(R.drawable.ic_launcher_background); menuItem3.setTitle("菜单三"); return super.onCreateOptionsMenu(menu); }
