copied!<p>I'd use MarvinLabs approach, but implement the while cycle in a different way:</p> <pre><code>public class Locate extends MapActivity { // ... private MyLooper mLooper; public void onCreate(Bundle savedInstanceState) { //... mLooper = new MyLooper(); mLooper.start(); } public void onDestroy() { // Don't forget to stop the thread here and release the reference // held by the activity (else you will leak memory) mLooper = null; } private class MyLooper extends Thread { public void run() { while (true) { // Your code here //After executing your code, sleep for 1000ms try { Thread.sleep(1000); } catch (InterruptedException ex) { //Treat the exception } } } } } </code></pre> <p>Also, instead of while(true) you can have a variable that would serve has a flag to inform the while cycle when to stop. That would make things easier when it's time to stop the thread.</p> <p>That would be something along these lines: <strong>Modified to use Handler</strong></p> <pre><code>public class Locate extends MapActivity { // ... private MyLooper mLooper; public void onCreate(Bundle savedInstanceState) { //... mLooper = new MyLooper(new Handler()); mLooper.start(); //When it's time to stop mLooper.setKeepRunningFalse(); } public void onDestroy() { // Don't forget to stop the thread here and release the reference // held by the activity (else you will leak memory) mLooper = null; } private class MyLooper extends Thread { //Your flag private boolean keepRunning; private Handler locateHandler; public MyLooper(Handler locateHandler) { this.locateHandler = locateHandler; } public void run() { while (keepRunning) { //When you want to execute some code that accesses Locate objects do this locateHandler.post(new Runnable() { @Override public void run() { //Your code here //This code will be executed by the thread that owns the objects, thus not throwing an exception. } }); //After executing your code, sleep for 1000ms try { Thread.sleep(1000); } catch (InterruptedException ex) { //Treat the exception } } } //Method to change the flag to false public void setKeepRunningFalse() { this.keepRunning = false; } } } </code></pre>
