getstring

问题 I'm managing a JDBC database with Servlets/JSPs and one of the attributes I have in a table is a string which may or may not have spaces in between words. I have one JSP to display all the information and another one to edit it, on both I perform getString to a ResultSet and when I'm just displaying it it works fine, but on the edit JSP it only "grabs" the first word before the space and the rest of the string disappears. Here's part of the code: PerfilUsuarioConectado.jsp (the one I use to

问题 What is the difference between two ways to obtain a string from resources: setPositiveButton(R.string.some_string); OR setPositiveButton((getString(R.string.some_string)); ? In both cases I get the same result. 回答1: R.string.some_string is a public final static int that is a fixed ID to a specific String in your R.java file. This is generated automatically. getString(R.string.some_string) returns the String referenced by the above by reading the R.java file. It depends on the implementation

问题 I have a simple query regarding ResultSet.getString() method in java for JDBC. Suppose the value in the Database column is having a \ which is javas escape character e.g. \n or \t etc. When i retrieve the value as getString() i see one more escape character is getting added and the actual meaning of this \n is now a string literal only. So i had to unescape java and then use it properly. String s= rs.getString("col_name"); When s contains `\n': System.out.println(s) output: \n After

问题 When programming for Android sometimes you have to use static methods. But when you try to access you resources in a static method with getString(R.string.text) you'll get an error. Making it static doesn't work. Does anyone knows a good way around this? The resource files in Android are very helpful for creating things in different languages or making changes to a text. 回答1: One way or another, you'll need a Context for that... For static methods this probably means you need to pass along a

问题 I have an Android application with English strings in values/strings.xml. For each string in that file, I have an entry in values-ja/strings.xml with the Japanese translation of that string. If I set the emulator, a Nexus One or Nexus S to Japanese, the UI shows Japanese text throughout. Most of the time. Sometimes, some portion of the UI will appear in English, even though the current locale is ja-JP. For instance, I wrote this test code in the onCreate() method of one of my activities: Log

问题 this is my strings.xml <resources> <string name="alert_internet">out</string> </resources> I am trying to call this string in my main activity like below: final String net = getString(R.string.alert_internet); I also checked my R.java file too, the int of 'alert_internet' exists.

What am I doing wrong trying to get a simple string? this is my log.cat 09-23 13:17:33.092: E/AndroidRuntime(21302): at android.app

问题 I have an array of bytes that I receive from an external entity. It is a fixed size. The bytes contain a unicode string, with 0 values to pad out the rest of the buffer: So the bytes might be: H \0 E \0 L \0 L \0 \0 \0 \0 \0 \0 ... etc I'm getting that buffer and converting it to a string like so: byte[] buffer = new byte[buffSize]; m_dataStream.Read(buffer, 0, buffSize); String cmd = System.Text.Encoding.Unicode.GetString(buffer); What I get back is a string that looks like this: "HELLO\0\0

问题 I have a google spreadsheet that sends student information contained in a column that is queried and concatenated from another sheet. The queried information is separated by carriage returns. This column is then emailed to families triggered by a formula that calculates how many carriage returns should be in the cell. That part I have taken care of in the sheet itself. I need assistance with emailing the column and maintaining the format of the cell. I've been able to do that with the code I

Possible Duplicate: Dynamic Resource Loading Android In Android, I can load a string from the resources with String s = getString(R.string.keyName) .
