public class SysApplication extends Application {
private List<Activity> mList = new LinkedList<Activity>();
private static SysApplication instance;

public synchronized static SysApplication getInstance() {
if (null == instance) {

return instance;
}
// add Activity
public void addActivity(Activity activity) {
mList.add(activity);
}
public void exit() {
try {
for (Activity activity : mList) {
if (activity != null)
activity.finish();
}
} catch (Exception e) {
e.printStackTrace();
} finally {
System.exit(0);
}

public void onLowMemory() {
super.onLowMemory();

}
}
在每一个会访问到的页面avtivity中添加 SysApplication.getInstance().addActivity(this); 就可以了
然后再退出的按钮或者地方调用 SysApplication.getInstance().exit();
