how to capture long press volume down key in android?

Question

Just wondering whether anyone could tell me how to capture the long keypress of the volume down key in android.

Elaborated question:

I wanted to create a BroadcastReceiver which will receive volume long keypress event. (without any UI interaction). I know it's possible for the search button. is it available for the Volume Keys?

Thanks

Hi I dont know whats exactly is you requirement but what you can do is using above when you got event in any activity you can create a custom broadcast that the volume key is long pressed and use that in BL – ingsaurabh Mar 14 '11 at 07:01

Note that to handle onKeyLongPress() you should track event onKeyDown(). and override both of them. please note the following examples.

 @Override
public boolean onKeyDown(int keyCode, KeyEvent event){
    if(keyCode==KeyEvent.KEYCODE_VOLUME_UP){
        event.startTracking();
        return true;
    }
    return super.onKeyDown(keyCode,event);
}
 @Override
public boolean onKeyLongPress(int keyCode,KeyEvent event){
    if(keyCode==KeyEvent.KEYCODE_VOLUME_UP){
        //Do your stuff here
        return true;
    }
    return onKeyLongPress(keyCode,event);
}

Also note that onKeyDown by default returns false. So by triggering onKeyDown() volume won't be increased.

I think that it is in theory possibly to accomplish the capturing of long key presses of the volume button, but is ill advised. The process would involve overriding the onKeyLongPress() method.

As to why it is ill advised: Volume Control in android application and How can I manage audio volumes sanely in my Android app?

It has been discussed before and basically, the keys have default behaviors that should not be overwritten because it is possible to "break the behavior of the volume keys".
