Corrected two consecutive buttons for Android Processing

1. Variable initialization:

 
Private Boolean isexit = false; private Boolean hastask = false;
 

2. Button capture (for example, in the ontouchdown function for button listening)

 
Presshomekeycount localhandler = new presshomekeycount (); If (isexit = false) {isexit = true; If (! Hastask) {message localmessage = new message (); localmessage. what = 0; localhandler. sendemptymessagedelayed (localmessage. what, 500l);} else {If (mrecentapplication. getvisibility () = view. visible) {mrecentapplication. setvisibility (view. invisible); isexit = false; hastask = false ;}} else {If (mrecentapplication. getvisibility () = view. invisible) {mrecentapplication. setvisibility (view. visible );}}
 

3. Handle object

Public class presshomekeycount extends handler {public void handlemessage (final message MSG) {isexit = false; hastask = true ;}}
 

The above practice will have an endless loop, and I have improved it. The following is the improvedCode, There is no problem after testing, where the variable Initialization is the same

2. Key capture

If (isexit = false) {isexit = true; If (! Hastask) {message localmessage = new message (); localmessage. what = 0; localhandler. sendemptymessagedelayed (localmessage. what, 500l);} else {isexit = false; hastask = false; localhandler. removemessages (0); If (mrecentapplication. getvisibility () = view. visible) {mrecentapplication. setvisibility (view. invisible) ;}} else {If (mrecentapplication. getvisibility () = view. invisible) {mrecentapplication. setvisibility (view. visible);} localhandler. removemessages (0); isexit = false; hastask = true ;}
 

3. Handler object

Public class presshomekeycount extends handler {public void handlemessage (final message MSG) {isexit = false; hastask = false ;}}
