100, in the prompt operation menu on the mobile phone state hurdle action button that is used for control SD card functional switch is set in advance.Namely among the QuickOperationBar on the StatusBar of Android system a unmount_mount action button that is used for control SD card functional switch is set in the present embodiment.Wherein said QuickOperationBar is the prompt operation menu that is used for placing some action buttons commonly used that Qualcomm realizes.
200, receive the described prompt operation menu of the touch screen operation instruction unpack mobile phone of the drop-down touch-screen of user; When receiving the user and click described SD card functional switch action button and stop the operational order of SD card function, control system stops all SD card functions immediately so that user security is extracted the SD card, controls simultaneously the color that the color of described SD card functional switch action button is adjusted into disabled status.
Better, after described unmount_mount action button was shown as disabled status, the user can safety extracted the SD card, can not cause the entanglement of system application.Better, in the present embodiment, if the user does not want to extract described SD card after clicking described unmount_mount action button, when perhaps the user reinserts the SD card, same by clicking described unmount_mount action button, when user's described operational order was received by system, control system was recovered all SD card functions automatically, and control is adjusted into the color of described SD card functional switch action button the color of upstate.
Better, the concrete mode at QuickOperationBar interpolation unmount_mount button in the described step 100 is as follows:
At first in system/frameworks/base/packages/SystemUI/res/values/defaults.xm l file, increase by one:＜string name=" def_qs_item11 "〉qs_hotspot＜/string 〉, then QuickOperationManager will detect when obtaining all operations item, and according to the object of the operation of the newly-built control SD card functional switch of this character string:
new?SdCardQuickOperationItem(context)
Described object SdCardQuickOperationItem registers the monitoring event of touch-screen when system initialization, if there is the event of clicking described object (being described unmount_mount button) to occur after the registration, object SdCardQuickOperationItem just can receive corresponding click event.Action after the reception touch screen event is shown in following slice:
New AsyncTask＜Void, Void, Void〉() { asynchronous task of // executable operations
@Override
protected?Void?doInBackground(Void...?args)?{
If (mIsOn) { // unloading SD card
unmount();
mIsOn?=?false;
}
Else { // carry SD card
if(mount()==?StorageResultCode.OperationSucceeded)?{
mIsOn?=?true;
}
}
return?null;
}
}.execute();
Start by the way an asynchronous task and go to carry out the unmount_mount operation of SD card.
Further, the implementation that control system stops all SD functions immediately in the present embodiment is specially: by obtaining the IMountService service broker of SD card in the system, API(Application Programming Interface by described service broker, application programming interface) interface sends the concrete instruction that stops all SD card functions to the operating system of lower floor, can realize by following program segment:
IMountService mountService=getMountService (); // obtain the service broker
try?{
For (int i=0; I＜mStorageVolumes.length; I++) // execution unloading mountService.unmountVolume (mStorageVolumes[i] .getPath (), true, false);
}
Catch (RemoteException e) { // abnormality processing ... }
Corresponding, the user does not want to extract the SD card after stopping all SD card functions, when wishing to reactivate all SD card functions, only need to click described unmount_mount button, system receives user's click event, the moun instruction that recovers SD card function is carried out in control, can realize by following program segment:
IMountService mountService=getMountService (); // obtain the service broker
try?{
if?(mountService?!=?null)?{
For (int i=0; I＜mStorageVolumes.length; I++) // execution carry resultCode=mountService.mountVolume (mStorageVolumes[i] .getPath ());
}
}?else?{
Log.e(TAG,?"Mount?service?is?null,?can't?mount");
}
Catch (RemoteException ex) { // abnormality processing
//?Not?much?can?be?done
resultCode?=?INIT_ERROR_STATUS;
}
System can not carry out the relevant operation of SD card after the SD card is pulled out, therefore when the SD card is reinserted into after, should allow the SD card automatically by mount on, after the event that receives user program insertion SD card, can allow the SD card automatically by on the mount by following program:
public?void?onReceive(Context?context,?Intent?intent)?{
Log.i(TAG,?"onReceiveaction:"?+?intent.getAction());
If (intent.getAction () .equals (Intent.ACTION_MEDIA_MOUNTED)) { // carry event
MIsOn=true; // sign is set, with record SD card state
UpdateView (); // renewal interface
}
Else if (intent.getAction () .equals (Intent.ACTION_MEDIA_EJECT) // unloading event || intent.getAction () .equals (Intent.ACTION_MEDIA_REMOVED)
||?intent.getAction().equals(Intent.ACTION_MEDIA_UNMOUNTED))?{
MIsOn=false; // sign is set, with record SD card state
UpdateView (); // renewal interface
}
}
Therefore when needs system disables SD card function, the unmount event is carried out in control, and status indication mIsOn=false then is set, and can not carry out afterwards the unmount operation; The mount event is carried out in control when needs recover SD card function, and status indication mIsOn=true then is set, and can carry out afterwards the unmount operation.
