  सार्वजनिक वर्ग MyDrawableView विस्तार देता है देखें {संदर्भ इस संदर्भ <; सार्वजनिक MyDrawableView (संदर्भ संदर्भ, AttributeSet attr) {सुपर (संदर्भ); ThisContext = संदर्भ; } @ ओवरराइड संरक्षित शून्य पर डरा (कैनवास कैनवास) {सुपर। डॉन (कैनवास); अंतिम पेंट पेंट = नया पेंट (); paint.setColor (Color.BLUE); paint.setTextSize (12); Canvas.drawText ("ब्लाह ब्लाह", 0, 100, पेंट); }}  
  सार्वजनिक वर्ग MyActivity गतिविधि को बढ़ाता है {// आपके सदस्य चर घोषणा यहाँ // जब गतिविधि पहली बार बनाई गई है कहा जाता है @ क्रिएट पर सार्वजनिक शून्य (बंडल सहेजे गए इन्स्टेंसस्टेट) को ओवरराइड करें {// आपका कोड यहां सुपर। परम (सहेजे गए इन्स्टेंसस्टेट); setContentView (R.layout.xmllayout); LinearLayout svll = (LinearLayout) findViewById (R.id.svlL); Svll.setLayoutParams (नई LinearLayout.LayoutParams (300, 300)); }}

मैं ब्रेकपॉइंट लगा रहा हूं, लेकिन ब्रेकपॉइंट कभी भी onDraw () विधि के अंदर नहीं मारा जाता है, क्या गलत है?

MyDrawableView कन्स्ट्रक्टर में setWillNotDraw (गलत) जोड़ें मूल उत्तर है।

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
