Overview:Based on the previous blog, "Android Exit Program (top)-Singleton mode ", we learned how to use Singleton and loop traversal to exit our application. This blog is going to solve the problem from another angle--broadcast. That is, when you

Public boolean onKeyDown (int keycode, keyevent event) { //Two return exit program if (keycode = = keyevent.keycode_back) { if ((System.currenttimemillis ()-mexittime) > ) { Toast.maketext (This, R.string.toast_twice_press_back_to_exit,

In the source code, the fire ant completely encapsulates the function of the double-exit program: Doubleclickexithelper classThis type of source analysis is as follows:1 in the constructor, the device context is passed in, the interface of exiting

The Android program has a lot of activity, such as the main window a, calling child window B, and child window B calling the child window C,back returns child window B, how to close the entire Android application in B? The following cloud Habitat

1,Android Double-click Back button to exit the program Idea: When the user presses the return key, a timer is set to monitor whether the exit is realized within 2 seconds, and if the user does not press the back key again, clears the effect of

This should be an old question, I would like to summarize the following: (I just touch windows programming I hope you have a lot of advice)1. Come up with one of the most reckless.Directly through exit (0), exitprocess (0); //Bad usageGuessing that

1.this.   Close (); Just close the current window, if it is not the main form, you can not quit the program, and if there is a managed thread (not the main threads), also can not cleanly exit;2.application.exit (); Forces all messages to abort,

Control must be entered can, but I quit the program when I asked me to enter a value to exit, this is too sick, I believe many comrades in the SAP program has been disgusted by this problem.Standard procedure We will not say, endure, the new

At the end of last year when I was learning Android to write a demo, again want to learn to write a double exit logic, but at that time to see good dozens of lines of code and logic on the spot, but recently in the project, suddenly think of this

1.this.   Close (); Just close the current window, if it is not the main form, you can not quit the program, and if there is a managed thread (not the main threads), also can not cleanly exit;2.application.exit (); Forces all messages to abort,

overriding this method is done under the corresponding Java file. Private LongEdittime=0; @Override Public BooleanOnKeyDown (intKeyCode, KeyEvent event) { if(keycode==keyevent.keycode_back&&event.getaction () = =Keyevent.action_down)

Test code: public class Testhook {public static boolean hookFlag = false;public static void main(String[] args) { Thread shutDownThread = new Thread() { public void run() { TestHook.hookFlag = true; try {

  Private long exittime = 0; /** * Capture Return Event button * * For this activity to inherit tabactivity with OnKeyDown no response, so instead of dispatchkeyevent * General activity Onke Ydown on it. * * @Override public boolean

The key operation of the Android system is first processed in Dispatchkeyevent, then onkeydown (int keycode, keyevent event) and onkeyup (int keycode, keyevent Event).In the same vein, touch operations are processed first in dispatchtouchevent and

in the development of the application, there is a feature is very common, that is, quickly double-click the Return button, and then realize the function of exiting activity. I read a lot of information on the Internet code, summed up, there are two
