android - How do you implement the Honeycomb purple/black gradient PreferencesActivity theme? -

-

I am using a selector to select topics for my preference: 

  & Lt; Style name = "standard theme selector" origin = "Android: Theme. Holo" & gt; & Lt; / Style & gt;   
 The app is run in Aclaire +, but I want to use it in the appropriate topic in Honeycomb.  
 This selector looks like priorities activity Honeycomb dark style instead of gingerbread style, the background behind the gray list view is pure black rather than a purple / black or brown / black shield. I have seen the purple theme in system settings and browser settings. I've seen a gray version in the YouTube app.  
 I have also noticed that the shield is visible for only one moment in the form of AIDS, and the color of the gradient matches the color of the app's activity activity.   
 
 
 To get a bitmap background, you have to turn on hardware accelerated drawing for your activity / app. Also, make sure that you set up Android: targetSdkVersion = "11" or later.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
