implement the iOS round button in Android -

-

I'm trying to create an iOS round button in Android. As you can know, the Android button has a gray background While the iOS round button has a clear background, I should use the styles and themes to get it.

However, I do not know how to piece things together. Can someone please give some advice?

Thanks

No need for style or theme. The trick with the buttons on Android is to use a different image for each state, and then combines them with a selector xml. You can put something like this in your doozleable directory and refer to it as an image: 

  & lt; Selector xmlns: android = "http://schemas.android.com/apk/res/android" & gt; & Lt; Item android: state_window_focused = "false" Android: state_enabled = "true" android: drawable = "@ drawable / btn_default_small_normal" /> & Lt; Item android: state_window_focused = "false" Android: state_enabled = "false" android: drawable = "@ drawable / btn_default_small_normal_disable" /> & Lt; Item Android: state_pressed = "true" android: drawable = "@ drawable / btn_default_small_pressed" /> & Lt; Item android: state_focused = "true" Android: state_enabled = "true" android: drawable = "@ drawable / btn_default_small_selected" /> & Lt; Android Android: state_enabled = "true" android: drawable = "@ drawable / btn_default_small_normal" /> & Lt; Item Android: state_focused = "true" android: drawable = "@ drawable / btn_default_small_normal_disable_focused" /> & Lt; Item Android: Dragon = "@ Drable / Btn_default_smml_armel_adgable" /> & Lt; / Selector & gt;   
 Then just set the background picture for this background. See for more information.

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...

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...
