Android screen navigation issue -

-

मुझे एक स्क्रीन नेविगेशन सवाल मिलता है। 1. गतिविधि ए-> गतिविधि बी 2. गतिविधि बी पर, गतिविधि ए (गतिविधि बी-> गतिविधि ए) पर वापस जाने के लिए एक एक्शन बटन पर क्लिक करें 3. गतिविधि ए पर, गतिविधि बी पर वापस जाने के लिए एक रद्द करें बटन पर क्लिक करें गतिविधि ए-> गतिविधि बी)।

मैं गतिविधि बी को दो बार नहीं बनाना चाहता हूं। क्या दूसरे चरण में गतिविधि बी को बचाने का एक तरीका है? धन्यवाद।

क्या कुछ बड़ा है जो बी में आरंभ होता है जो संक्रमण को धीमा कर रहा है? मैं सिर्फ सिस्टम को इसकी बात करता हूं, आप onSavedInstanceState और onRestoreInstanceState ।

के साथ एक गतिविधि में स्थिति का अनुकूलन कर सकते हैं

Using KV lang on my Python code, I have taken a hard time trying to instantiate a dynamic class, the following Consider the code: My test.kv file looks like this: & lt; MyPopup @ popup: Title: 'Hello' size_hunt: (1, .6) Grid layout: ID: RouteGrid column: 2 padding: ['8dp', '4dp', '8dp', '4dp'] Difference: '8dp' label: text: 'some text here' button: text: 'OK' On_press: do_something () & lt; MyGrid & gt;: Rows: 1 Button: Text: 'Show Popup' on_press: root.pop.show () Then import Kivy.app into my test.py: I get the following error: raise Factory Exception ('Uncount Class' '% name) kivy.factory.FactoryException: Unknown class Can anyone tell me how to do this properly, what do I remember? If you need more information please let me know Thank you. Takes a call to the factory before the KV file is loaded, so you want the class to Are not yet in existence. As long as no clas...

python - mayavi mapping a discrete colorbar on a surface -

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
