android - Run a function over and over again -

-

I'm new to writing an app for Android. I have had the experience of writing programs in non object-oriented program language, but also want to learn this method of programming.

I would like to start simple and do the following: a button and a vibrator press will be triggered in a specific method until the phone is pressed again

I know if you say Are: vibrator.vibrate (pattern, 0); That this pattern will repeat. But for example I want to turn the screen on and off in that pattern.

What would be the right way to do this?

Thank you very much for your help. 

  package com.trick-design.simple_prog; Import android App Importroid.os.Bundle; Import android.content.Context; Import Android.os.Vibrator; Import android.view.View; Public square simple_prog activity extends to {private long} pattern = {100, 100, 300, 100, 900, 1050}; Boolean vibrator_on = true; /** Called when the activity is first created. * / @Override Public Zero onCreate (bundled savedInstanceState) {super.onCreate (savedInstanceState); SetContentView (R.layout.main); } @ Override protected void onStart () {super.onstart (); FindViewById (R.id.vibrate_button) .setOnClickListener (vibrate_click_listener); } See. OnClickListener vibrate_click_listener = View new. OnClickListener () {Click on Public Zero (see V) {vibrator Vibrator = (vibrator) getSystemService (reference .dbBRATOR_SERVICE); Vibrator Vibration (pattern, -1); }}; @ Override Protected Zero ontop () {super.onStop (); // Activity is no longer visible (now it is "closed") @ Override Protected Zero at Desto () {Super. Onesteroy (); // activity is going to be deleted}}    
 
 
 In:  
 You will need to create a class that implements runnablas or extends the thread so that it can be done to prevent hanging in another thread. You can do this with a second class in the same * .java file - it allows the file to access variables from other classes:  
  Private class VibrateRunner implements Runnable {public Void run () (while (vibration)) {executeVibrate (); }} Execute private zeros () {vibrator.vibrate (pattern, -1); }}   
 Your click listener needs to be smart enough to start / stop threads:  
  // Thread class variable Create a Thread BgThread = null; OnClick (see V) {// you already started the thread - stop it if (bgThread! = Tap) {vibrate_on = false; BgThread.join (); Return; } // need to turn on thread vibrate_on = true; Runner runner = new vibration (); BgThread = new backgroundread (runner); BgThread.setDaemon (true); // run it in background bgThread.start (); }   
 This should take you in the right direction. Note: I dedicate to deal with a lot of exceptions here - read something on Java threads to feel for it. Eclipse will also help you to produce corrective / catching blocks.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
