What I want to carry out is that the handle of the SlidingDrawer will be dragged by my finger, and when My finger leaves the screen, the handle of the SlidingDrawer will be just stop there and don't slide to top or bottom.

If I setOnTouchListener for a view the only events I get are ACTION_DOWN events. What do I need to do to capture ACTION_MOVE events which should occur when the user drags a finger across the view?
View 3 Replies View RelatedI decided to start pipelining input to increase responsiveness in my games. Basically what I do is when the activity receives a Key or Motion event, it sends it to a feed method in the game, which encapsulates it with a time and whatever else I need and puts it in a queue then immediately returns so the UI loop is never held up waiting for long. The main loop later processes the queue, applying the events in it at the appropriate times.
This works great and makes the games snappy, although now I'm starting to miss touch events intermittently. I realized that the events could be recycled objects and that could make them not safe to queue. Is this the case or is it safe to queue them for deferred processing like I'm doing?
I am curious about the safety of this method I have considered using for passing touch events in my Android application (and testing my understanding of concurrency in Java). Here's the basics:
I have a SurfaceView hooked up to SurfaceHolder.Callback to get user input events, mainly the onTouchEvent callback. After the onTouchEvent method is invoked, I see if event.getAction() == MotionEvent.ACTION_UP and, if so, call a method I have named postTouchEvent which is a member method of my app thread that updates the application's state and draws to the canvas. Code...
Now I understand that it is certainly not atomic, but since I treat it as immutable after receiving it from framework, won't this work? (Instead of synchronizing the post method and the if statement, which I have no problem doing, but I'm asking to learn.)
Here are my thoughts. I know I will have a valid reference to the object but I am unsure in what state I will actually see the object. While testing everything is working out just fine but I am aware of how uncommon threading exceptions can be, even if something is broken.
Also, I can see one problem with this: If another MotionEvent comes though, it's possible that inputEvent in the run() method will be set to a different event than the one that was referenced when this.mInputEvent != null was checked, but this really isn't an issue.
So, is there anything I am missing or, for my purposes, should this be ok?
Has anyone used the sliding drawer widget? I'm trying to get the widget to slide out from top to bottom, but right now it only seems to support bottom to top or right to left. Any suggestions on how to get it to slide out from the top?

Say i already have an XML file, and i want to add a sliding drawer to it..i also want to add a textview and listview object, and some buttons in it...how would i go about doing that?

I tried to construct SlidingDrawer widget programmatically, but had no luck. The JavaDoc says the constructor needs "AttributeSet attrs" parameter, which is "a specified set of attributes defined in XML".
I provided my own implementation of AttributeSet interface, with all the attributes mentioned in JavaDoc, but got a weird ClassCastException - it seems that it assumes the attrs parameter is of type TypedArray, which seems to be impossible to use as base class (constructor hidden). Is there a way to construct SlidingDrawer programmatically and what is the correct contract to use it ? It is no way clear from the documentation.
I have a SlidingDrawer that pops up from the bottom of the screen and fills the screen about 80%. Even though the SlidingDrawer view is in focus, it is still possible to click on items, buttons and other elements in the view that is behind the SlidingDrawer. When SlidingDrawer is active/pulled up/in focus, I want to disable the entire view behind it so it will not be able to recieve clicks and touches. Is there a good way to disable an entire view? I have tried setEnable(false) and setClickable(false) but neither of them work.

I'm currently having trouble with a SlidingDrawer. I want it to be closed when the application starts so it doesn't get in the way. However, it is determined that it will be open, despite putting slide.close() in the onCreate() of my activity. It seems to be closed if i use slide.animateClose() instead, but this slows my application down loads.
How do I make it closed by default? code...
I'm using a slidingDrawer in my application that has its handler placed at the bottom when in portrait mode. When the user switches to landscape mode (widescreen) I would like to have the handler located on the left. When I change the orientation from vertical to horizontal, the handler is placed on the right.
I have defined my layout XML like this:
<SlidingDrawer
android:id="@+id/l_drawer"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:handle="@+id/l_handle"
android:content="@+id/l_content"
android:orientation="horizontal"
android:layout_gravity="left>
Anyone have an idea for how to make it slide from left to right ?
I'm trying to change the icon on the handle when i try to open the slidingdrawer.
When I extract the handle from the view and sets the onclicklistener or ontouchlistener it seems to never get trigget.code...
I was hoping this code should log "onClick" message, but it doesn't. Any ideas?
I'm trying to get a sliding drawer to pull down from the top in my application, but I can't figure out a way to do it. Any help?

I cant find a way to set the orientation on my SlidingDrawer when i change from landscape mode to portrait mode visa versa. Initially i set the orientation by xml to vertical. I need to change the orientation to horizontal when the phone is in landscape mode, so i get the handle on the left.

View 3 Replies View RelatedI have a bit of a problem with a SlidingDrawer that I created and that should go over my VideoView. When the activity is opened for the first time you can see the slider above the video and when you tap it, it slides open. However, as soon as you close the slider it seems to disappear underneath the VideoView and is not visible anymore. It is still there and when you tap the location where the handle is located the slidingDrawer reappears, but I would rather prefer if it wasn't hiding all the time ;) If anyone knows what I can do about that and help me out, that would be really fantastic because I have been trying for hours now and I have no idea what I should do. I also haven't found a similar issue or a solution for that.

I'm trying to create a sliding drawer in code, but I don't understand what to do for the AttributeSet part of the constructor.
What do I need to do for that?
Also, how do I define in code where the slider is going to show up?
I'm interested in using it for one of my apps and I was wondering how I can use one of them.
Are there any other similar widgets out there for 2.0+?
I want to port my application on all android devices, and I want to have the right/left animation on the activities transition on all android platform versions. I know that this feature is implemented in the 2.0 version. How can I implement this feature for the lower versions?
