Android click button populate textview -

-

This is Android's week for me!

I am making the program a text view, two labels and a button in the same activity. The idea is that the text view receives a string from the user. The user clicks the button and the textive string is passed to a proc that returns string results, and the string result is assigned to one of the labels. 

  Click Public Zero (see view) {Sresults = showPP (ttsymbol.getText (). ToString (.) Trim ()); }   
 But this does not work, because "the last local variable can not be indexed because it is defined in an enclosed type"  
 I think Is that what I think is going wrong, but is an alternate way to return the results so that they can be displayed in the label? Or is it necessary to create a new dialog inside the onClick function to show them?  
 Thank you!   
 
 
 If you definitely change values, then there is no point in making it last. Used for  last  constant values. 
 
 You should set a price directly in the label view. Label view references can be final.  
  Click Public Zero (see view) {labels.set text (ttsymbol.getText () .toString (.) Trim ()); }

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. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

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...
