Android EditText Text length restrictions have a very simple way of restricting: adding Android:maxlength= "N" to EditText in an XML layout fileBut this simple way may sometimes not meet some of the more serious needs, this time need to use another way to limit the length.This is achieved by Inputfilter:Private classNamelengthfilterImplementsInputfilter {intmax_en; String regEx= "[\\u4e00-\\u9fa5]"; PublicNamelengthfilter (intmax_en) { Sup

Received last said, mainly on the last question, I think is the Android bug, Uncle Lee think is cocos2dx bug, asked me to submit a bug. So I went on to study the next.The last thing I said would call the Java layer function to create an image, and then set it as a texture to the sprite, where it crash, where the code is as follows:public static void Createtextbitmapshadowstroke (String pstring,final string pfontname, Final int pfontsize, final float f

According to the previous response, the problem was mainly caused by the android bug. Uncle Li thought it was a cocos2dx bug and asked me to submit the bug. So I continued my research. In the previous example, the java-layer function will be called to create an image and then set it as a texture to the sprite. Here the code is as follows: public static void createTextBitmapShadowStroke(String pString,final String pFontName, final int pFontSize, fina

We often need to judge in the program whether a character is a character in CJK (Chinese, Japanese, Korean) language. For example, in Contacts, the program needs to determine the language of the contact name. Today, we will introduce a method for determining the language of a character in NameSplitter. Take determining whether the

In our project, the core part is written using JNI, Convert the Java string to the C string. The conversion of the string is as follows: const char const *p_passwd = (*env)->GetStringUTFChars(env, j_passwd, NULL); Previously in Android 2.x, everything was normal. An exception occurred after the upgrade to 4.0. Error exits. Trace found problems: j_passwd in the program is sometimes null, resulting in. I didn't handle j_passwd being null at the tim

This example describes the Android programming EditText method for displaying related prompts without entering specific characters. Share to everyone for your reference, specific as follows: First look at the effect of the picture: The source code is as follows: Layout file: Mainactivity.java: Package com.example.edittext2; Import android.app.Activity; Import Android.os.Bundle; Import Android.view.Menu; Import Android.view.View;

Android Secret Code Many of us should have done this, open the dial-up keyboard input *#* #4636 #*#* and other characters will pop up an interface to display some information about the phone, this feature in Android is called the Android secret code, In addition to these system preset secret code, we can also implement their own secret code, and implementation i

Today, the program has a bug. If you change the APK name to include "%", the "Resolution package is faulty" will occur and the installation will not continue, I read the code for installing the program for half a day: 01. intent intent = new intent (intent. action_view); 02. intent. setflags (intent. flag_activity_new_task); 03. intent. setdataandtype (URI. parse ("file: //" + filepath), 04. "Application/vnd. android. package-Archive "); 05. getapp

When I want to output enough debugging information in Logcat today, we find that the information returned from Logcat is obviously less in the following section.Feel a bit strange, thought is the code problem, looked for a bit, found not;So guge. The original logcat on the implementation of the memory allocation for the message is about 4k. So the content is discarded directly;Not output;Also found that logcat for "\ n" line break automatically as a symbol is automatically separated into multipl

When developing applications using ndk, character encoding conversion is sometimes required. Here we use the open source library icon for character encoding conversion. The Code is as follows: Char * convertstring (const char * fromcode, const char * tocode, const char * Source){Size_t retlen = 0;Size_t inbytesleft = strlen (source );If (! Strncmp (fromcode, "UTF-16LE", 8 )){Inbytesleft = gg_wcslen (unsigne

Unicode: Wide-Byte Character Set1. How to obtain the number of characters in a string that contains both single-byte and double-byte characters?You can call the Runtime Library of Microsoft Visual C ++ to contain the function _ mbslen to operate multi-byte strings (including single-byte and dual-byte strings.Calling the strlen function does not really know how many characters are in the string. It only tells you how many bytes are before the end of 0.

You do not know the character set and encoding (encoding and character set encoding), but do not know the encoding character set. In my previous article, a friend proposed the differences between character sets and encoding. I will discuss it with you here. The difference between c
