Open src//AndroidTimerTaskExample.java file and paste the code below.ĪndroidTimerTaskExample.java package com.javacodegeeks. Creating the source code of the main Activity In this article, it’s been discussed how the Date and Time values. The current date and time are of the type Long which can be converted to a human-readable date and time. Here we set the dimens for the paddings of our activity_main.xml layout.ģ. Date and Time in Android are formatted using the SimpleDateFormat library from Java, using Calendar instance which helps to get the current system date and time. This xml should be placed in the res/values/dimens.xml folder. In the layout above, we have used the attribute android:paddingBottom that uses a variable indicates the value of the padding that we want to have: In order to set our sizes, in Android, we have the dimens.xml. Open res/layout/activity_main.xml, go to the respective xml tab and paste the following: We are going to make a very simple layout xml for our activity, that only consists of a LinearLayout that contains the necessary textviews and buttons. We will use the following tools in a Windows 64-bit platform:Ģ. However, in this tutorial we are going to see how to use a TimerTask, and we will make an application that will handle with recurring events. You can also learn more about Android Handler in the JavaCodeGeeks Android Handler Example. This is why Handler is very common amongst Android programmers and projects. Literally, Handler is a native android class that handles memory leaks problems in a better way than Java-Timer does. In Android, Timer and Handler can be used for pretty much the same reasons, and in the same way. This may result in a series of bunched-up runs (one launched immediately after another) if delays prevent the timer from starting tasks on time. With fixed-rate execution, the start time of each successive run of a task is scheduled without regard for when the previous run took place. With the default fixed-period execution, each successive run of a task is scheduled relative to the start time of the previous run, so two runs are never fired closer together in time than the specified period. We will use the abstract class TimerTask. In this example, we are going to see, how a java.util method, can help us deal with timer recurring tasks that are scheduled with either a fixed period or a fixed rate on Android.
