I would like to do some tests on SlidingDrawer however i always found RuntimeException when SlidingDrawer.onMeasure is called i check the code and think the exception is caused by unspecified MeasureSpec
so i would like to ask how to setup the MeasureSpec in SlidingDrawer?
Well, preventing an orientation change is easy. But what about doing it at run time.
Say, I have an activity which supports orientation change in normal situations. It has say three Edit Texts.
There's also a button, which when clicked would do some processing in a thread while showing a ProgressDialog which is not cancellable.
Ok, so till the user hits the Button, I want the activity to be able to adapt the orientation changes. I have two layouts files for each orientation with different layout schemes.
What I want is this. Once the user clicks on the button, and the ProgressDialog is showing, I don't want the activity now to be re- created again when the orientation changes. So, before showing the ProgressDialog, is there any way to tell the Activity not to handle Orientation change?
Also, once the process is complete, and the ProgressDialog is removed, I want the Activity again to be able to handle orientation changes.
I have a button that plays an audio file on its click listener. If the button is clicked again and again while the audio file is being played then the app crashes. What's the solution?
Here is some code for reference...

I am creating an Android app that includes a third party jar. That third party jar utilizes internal logging that is failing to initialize when I run the app, with this error: "org.apache.commons.logging.LogConfigurationException: No suitable Log implementation".
The 3rd party jar appears to be using org.apache.commons.logging and to depend on log4j, specifically log4j-1.2.14.jar. I have packaged the log4j jar into the Android app. The third party jar was packaged with a log4j.xml configuration file, which I have tried packaging into the app as an XML resource (and also as a raw resource).
The "No suitable Log implementation" error message is not very descriptive, and I have no immediate familiarity with Java logging. So I am looking for likely causes of the problem (what class or configuration resources might I be missing?) or for some debugging technique that will result in a different error message that is more explicit about the problem. I do not have access to source code for the 3rd party jar.
Here is the exception stack trace. When I run the app, I get the following exception as soon as one of the third party jar classes attempts to initialize its internal logging. code...
I have a custom view on which I need to call a method from my activity after the view has been measured in onMeasure. I would like to know exactly when onMeasure is called in the View layout process. It looks like onMeasure is called after my activity´s onCreate, onStart, and onResume. I could override onMeasure and maintain a variable that contains whether the view has been measured or not. However it would be nice to know if there is a rule that relates onMeasure to the activity lifecycle?
View 4 Replies View RelatedI have a View that I've placed into a ScrollView.The View paginates text.If the text changes, then the height of this view will also change (expand or contract, depending on whether the new text takes more vertical space or less).For debugging, I draw a rectangle around the view to show its current size. After I repaginate, I cannot get Android to cause the View to change its size -- I have tried calling measure() myself, calling requestLayout(), and calling forceLayout() -- even though my overloaded onMeasure gets called, and calls setMeasuredDimension() with the correct values, the view remains the same size as it was before repagination. What am I missing?
View 2 Replies View Related1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...
I created a sql lite database with the following columns:
static final String dbName="demoDB";
static final String tableName="Employees";
static final String colID="EmployeeID";
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL("CREATE TABLE "+tableName+" ("+colID+" INTEGER PRIMARY KEY AUTOINCREMENT, "+
colName+" TEXT, "+colAge+" Integer);");
I want to select all the records in the database like this and display them in a gridview:SQLiteDatabase db=this.getWritableDatabase();Cursor cur= db.rawQuery("Select "+colName+", "+colAge+" from "+tableName, new String [] {});String [] from=new String []{DatabaseHelper.colName,DatabaseHelper.colAge};
int [] to=new int [] {R.id.colName,R.id.colAge};
SimpleCursorAdapter sca=new SimpleCursorAdapter(this,R.layout.gridrow,c,from,to);
GridView grid=(GridView)findViewById(R.id.grid);
grid.setAdapter(sca);but i receive the following exception:java.lang.IllegalArgumentException: column '_id' does not exist.the db table does not have a column with name '_id'so what is wrong with this code
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?

View 3 Replies View RelatedI 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.
View 2 Replies View RelatedI'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...
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.
View 6 Replies View RelatedI'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 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 1 Replies View RelatedI'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here.

View 15 Replies View RelatedIs it possible to load my main.xml layout file in onCreate() and then later in the app, switch to a new XML layout? I've tried placing setContentView() later on in the app but that seems to not actually set the new View because my references to objects in the newly set xml layout file are returning as null. I've tried doing some layout inflating using the LayoutInflater but I'm having no luck (I'm probably doing something wrong)... So is there any other way to swap layout xml layouts at runtime?
