Intent notificationIntent = new Intent (this, this.getClass ()); / / click on the notification to jump Activity

StatusBarView.java This class has two important methods,
onTouchEvent and onInterceptTouchEvent
These two methods are used mainly in response to the drop-down event statusbar and extended so that it can display the status bar.
StatusBarService.java there is an inner class, Launcher, the class has a method onClick:

 
public void onClick (View v) {
try {
/ / The intent we are sending is for the application, which 
/ / Won't have permission to immediately start an activity after 
/ / The user switches to home. We know it is safe to do at this 
/ / Point, so make sure new activity switches are now allowed. 
ActivityManagerNative.getDefault () resumeAppSwitches ();. 
} Catch (RemoteException e) {
} 

if (mIntent! = null) {
int [] pos = new int [2]; 
v.getLocationOnScreen (pos); 
Intent overlay = new Intent (); 
overlay.setSourceBounds (
new Rect (pos [0], pos [1], pos [0] + v.getWidth (), pos [1] + v.getHeight ())); 
try {
mIntent.send (StatusBarService.this, 0, overlay); 
} Catch (PendingIntent.CanceledException e) {
/ / The stack trace isn't very helpful here. Just log the exception message. 
Slog.w (TAG, "Sending contentIntent failed:" + e); 
} 
} 

try {
mBarService.onNotificationClick (mPkg, mTag, mId); 
} Catch (RemoteException ex) {
/ / System process is dead if we're here. 
} 

/ / Close the shade if it was open 
animateCollapse (); 
} 
} 

Feeling mBarService.onNotificationClick (mPkg, mTag, mId); This method should handle the key message is. But useless to the upper pass over contentIntent parameters. Do not understand
