我有以下代码,希望每30秒循环一次.
MyLocation myLocation = new MyLocation();
public LocationResult locationResult = new LocationResult() {
@Override
public void gotLocation(final Location location) {
GeoPoint myGeoPoint = new GeoPoint(
(int) (location.getLatitude() * 1000000),(int) (location.getLongitude() * 1000000));
myMapController.animateTo(myGeoPoint);
myMapController.setZoom(10);
lat = location.getLatitude();
lon = location.getLongitude();
new OverlayTask().execute();
Timer timer;
timer = new Timer();
timer.scheduleAtFixedRate(new MyTimerTask(),30000,30000);
}
};
一旦获得位置,就会被解雇,并且OverlayTask执行得很好,当分配给菜单项强制执行时,它也会执行.
但是在计时器内部,我得到一个错误.
public class MyTimerTask extends TimerTask {
public void run() {
try {
Log.i(">>>>>>>>>>>> Refresh: ","Success");
new OverlayTask().execute();
} catch (Exception e) {
Log.e(">>>>>>>>>>>> Error executing MyAsyncTask: ",e.getMessage(),e);
}
}
}
错误是…
Error executing MyAsyncTask:(2573): Only the original thread that created a view hierarchy can touch its views.
最佳答案
使用
原文链接：https://www.f2er.com/android/531578.htmlrunOnUiThread方法：
public class MyTimerTask extends TimerTask {
public void run() {
runOnUIThread(new Runnable(){
public void run(){
try {
Log.i(">>>>>>>>>>>> Refresh: ","Success");
new OverlayTask().execute();
} catch (Exception e) {
Log.e(">>>>>>>>>>>> Error executing MyAsyncTask: ",e);
}
}
});
}
}
