  • Can I increase a buttons onclick-area programmatically?

    - by sandis
    Sometimes I have a button in my UI that it is so small that it is difficult to click. My solution so far has been to add a transparent border around the button in photoshop. Just increasing the padding on the button does not work, since this will also stretch the image. Since it is kind of a fuss to open photoshop each time I want to change the clickable surface, is there any way to do this programmatically? I have tried placing a framelayout behind the button and make it clickable, but then the button wont change appearance on touch as it should. Ofcourse I could also add a ontouchlistener on the framelayout which changes the buttons appearance, but then it quite some code if I have several of those buttons. Cheers,

  • Send Logcat output of an App to an EmailAdress

    - by Sebi
    Hi Were now testing our application with a few friends. Sometimes there are some errors which dont throw an exception. So I don't really know whats the problem was. So i thought it would be a good idea to implement a menu item which allows to send the logcat file to a email adress, so that we can examine the logcat. Unfortunately I didnt found a hint in the Internet how to extract the Logcat from a phone. How to send a email shouldn't be the problem.

  • GoogleAuthUtil: Daily Limit for Unauthenticated Use Exceeded

    - by Copa
    I am using the Google Client API and the GoogleAuthUtil.class to get access to the user's Google Drive Account. String scope = "oauth2:" + DriveScopes.DRIVE; String token = GoogleAuthUtil.getToken(getContext(), account.name, scope); This is the whole magic. It worked the whole day but since a couple of hours I receive the following message when sending API calls: com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden { "code": 403, "errors": [ { "domain": "usageLimits", "message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.", "reason": "dailyLimitExceededUnreg", "extendedHelp": "https://code.google.com/apis/console" } ], "message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup." } I dont know how to use a API Key from the console instead of an oauth2 authentication. There are two different "getToken()" messages. One has four parameters and the description for the last one says: extras: Bundle containing additional information that may be relevant to the authentication scope. But what do these information should look like? What informations do I have to put in the Bundle?

  • ListAdapters and WrapperListAdapter algorithm

    - by Matty F
    This logic is written in a function with signature private void showDialog(final AdapterView<? extends Adapter> parent, String title, String message, final Tag subject) Is there a better way of doing this? // refresh adapter SimpleCursorAdapter adapter; if (parent.getAdapter() instanceof WrapperListAdapter) { adapter = (SimpleCursorAdapter) ((WrapperListAdapter) parent.getAdapter()).getWrappedAdapter(); } else { adapter = (SimpleCursorAdapter) parent.getAdapter(); } adapter.getCursor().requery(); adapter.notifyDataSetChanged(); Also, is there any point in having AdapterView<? extends Adapter> in the signature and not just AdapterView<?>?

    I would like to make a LinearLayout that was created from xml invisible, and another LinearLayout visible to replace it. The replacement layout starts out as invisible.

  • is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified

    - by user355859
    is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified manifest.xml?? I know there are tools such as baksmali / smali to disassemble / re-assemble given classes.dex from .apk, but not sure limitation what could be modified from there on? I'm trying to add additional activity, to modify starting launcher activity (may be from androidmanifest.xml) from original apk, then re-pack and sign to make complete single .apk... all need to be done out of build time, no raw source or build structure visible, only .apk as input... ANY IDEA?

  • Install APK on ICS through Eclipse

    - by roboguy12
    I rooted my Incredible and flashed an ICS rom, and I can't seem to install an app through Eclipse for testing (or by manually pushing it through adb). I know I have to change the permissions of /data/local to write and execute others in order to allow APKs to be installed, but when I adb shell into my phone and call chmod o=wx /data/local I get a message saying Bad mode. What does this mean and how do I fix it? Thanks! EDIT: According to this question I need to change the permissions of /data/local in order for this to work; I'm receiving the same errors as the OP of that question.

  • No GPS updates on Galaxy S3

    - by Valelik
    I'm developing a GPS tracker and it works like a charm. But a couple of weeks ago a customer of me (a trackage company) bought Samsung Galaxy S3 for his drivers. And since that we have really strange behaviour of my app. The app receives location updates from GPS receiver, but after some hours of work it doesn't receive any location updates. I have registered the app for onGpsStatusChanged() too and in this time onGpsStatusChanged() was called (I see that GPS receiver have 10-17 satellites!), but the method onLocationChanged() was not called! After the service restart (=re-registering of LocationListener) it works again. It is really strange. It seems that after some hours of work the GPS reciever is not in the mood for calling onLocationChanged() :) Any idea what may be wrong?

  • Call an IOUSBDeviceInterface function on an obj-c object instead of a C structure

    - by b1onic
    Let's say I want to close an USB device. Here is a C structure representing the USB device: struct __USBDevice { uint16_t idProduct; io_service_t usbService; IOUSBDeviceInterface **deviceHandle; IOUSBInterfaceInterface **interfaceHandle; Boolean open; }; typedef struct __USBDevice *USBDeviceRef; Here is the code to close the device: // device is a USBDeviceRef structure // USBDeviceClose is a function member of IOUSBDeviceInterface C Pseudoclass (*device->deviceHandle)->USBDeviceClose(device->deviceHandle); Now imagine that the device properties are declared in an obj-c class @interface Device : NSObject { NSNumber idProduct io_service_t usbService; IOUSBDeviceInterface **deviceHandle; IOUSBInterfaceInterface **interfaceHandle; BOOL open; } @end How would I do to call USBDeviceClose() ?

What I want to do is use my GUI I have built for my app, but pull the information from a website.

I know this is a huge question, I'm just looking for what is actually needed to accomplish this, and then I can start researching from there. -- Or is it even possible?

  • Apply Quaternion to Camera in libGDX

    - by Alex_Hyzer_Kenoyer
    I am trying to rotate my camera using a Quaternion in libGDX. I have a Quaternion created and being manipulated but I have no idea how to apply it to the camera, everything I've tried hasn't moved the camera at all. Here is how I set up the rotation Quaternion: public void rotateX(float amount) { tempQuat.set(tempVector.set(1.0f, 0.0f, 0.0f), amount * MathHelper.PIOVER180); rotation = rotation.mul(tempQuat); } public void rotateY(float amount) { tempQuat.set(tempVector.set(0.0f, 1.0f, 0.0f), amount * MathHelper.PIOVER180); rotation = tempQuat.mul(rotation); } Here is how I am trying to update the camera (Same update method as the original libGDX version but I added the part about the rotation matrix to the top): public void update(boolean updateFrustum) { float[] matrix = new float[16]; rotation.toMatrix(matrix); Matrix4 m = new Matrix4(); m.set(matrix); camera.view.mul(m); //camera.direction.mul(m).nor(); //camera.up.mul(m).nor(); float aspect = camera.viewportWidth / camera.viewportHeight; camera.projection.setToProjection(Math.abs(camera.near), Math.abs(camera.far), camera.fieldOfView, aspect); camera.view.setToLookAt(camera.position, tempVector.set(camera.position).add(camera.direction), camera.up); camera.combined.set(camera.projection); Matrix4.mul(camera.combined.val, camera.view.val); if (updateFrustum) { camera.invProjectionView.set(camera.combined); Matrix4.inv(camera.invProjectionView.val); camera.frustum.update(camera.invProjectionView); } }

  • Dynamic ExpandableListView

    - by JLB
    Can anyone tell me how I can Dynamically add groups & children to an ExpandableListView. The purpose is to create a type of task list that I can add new items/groups to. I can populate the view with pre-filled arrays but of course can't add to them to populate the list further. The other method i tried was using the SimpleExpandableListAdapter. Using this i am able to add groups from a List but when it comes to adding children i can only add 1 item per group. public List<Map<String, String>> groupData = new ArrayList<Map<String, String>>(); public List<List<Map<String, String>>> childData = new ArrayList<List<Map<String, String>>>(); public void addGroup(String group) { Map curGroupMap = new HashMap(); groupData.add(curGroupMap); curGroupMap.put(NAME, group); //Add an empty child or else the app will crash when group is expanded. List<Map<String, String>> children = new ArrayList<Map<String, String>>(); Map<String, String> curChildMap = new HashMap<String, String>(); children.add(curChildMap); curChildMap.put(NAME, "EMPTY"); childData.add(children); updateAdapter(); } public void addChild(String child) { List children = new ArrayList(); Map curChildMap = new HashMap(); children.add(curChildMap); curChildMap.put(NAME, child); curChildMap.put(IS_EVEN, "This child is even"); childData.add(activeGroup, children); updateAdapter(); }
