symbols

I was working on Android Studio for adding a short toast message.(I was making an Android Wear Application) I couldn't know why this code has error on 'symbol R' . It says "Cannot Resolve Symbol R." import android.app.Activity; import android.content.Context; import android.content.DialogInterface; import android.os.Bundle; import android.support.wearable.view.WatchViewStub; import android.view.View; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; public class MyActivity extends Activity { private TextView mTextView; @Override protected void onCreate

I have the following code to create a plot . On the x - and y-axes there are symbols that appear on the screen, in a JPEG when I save my plot in that format, but not when I save the plot as a PDF . Is there alternative symbol to my \u2030 that will print in my PDF or another solution to my problem? See examples below of the correct (JPEG format) and the incorrect (PDF) plots . plot(c(-1,1), c(-1,1), bty = "n", type= "n", las = 1, cex.lab = 1.5, cex.axis = 1.25, main = NULL, ylab=expression(paste("Correlation Coefficient (r) for ", delta ^{15},"N"," \u0028","\u2030","\u0029")), xlab=expression

I have to use an API provided by a DLL with a header like this namespace ALongNameToType { class ALongNameToType { static void Foo(); } } Is there a way to use ALongNameToType::ALongNameToType::Foo without having to type ALongNameToType::ALongNameToType each time? I tried using using namespace ALongNameToType but got ambiguous symbol errors in Visual Studio. Changing the namespace name or removing it gives me linker errors. I don't know what's ambiguous, but you can avoid all conflicts with other Foo functions like this: namespace ALongNameToType { struct ALongNameToType { static void Foo(); }

I need to add the TM(trademark) superscript symbol next to a title in a C# string. is there anyway to possibly do this? Thanks! This answer is "\u2122" by Hans Passant™ Use the charmap.exe applet and copy/paste the character in your string literal.

If I do this: ('a 'b 'c) I get this: c Why? The link Hauleth posted is a good overview to symbols but the answer to your question is that calling a symbol as a function is equivalent to looking that symbol up in the first argument. ('a 'b) is equivalent to (get 'b 'a) The documentation for get shows that you can pass an optional third argument as the default. In your example 'c is treated as the default and returned since 'b is not a map and 'a can't be found. 来源： https://stackoverflow.com/questions/8219305/what-happens-when-i-pass-arguments-to-a-clojure-symbol

I am doing the below. All I get is the basic font, not my custom symbol font. Any ideas? Paint pnt = new Paint(); // SymbolNo is 38. Returns string "&" which is correct in normal font. String symbolText = Character.toString((char)SymbolNo); // Should adopt a symbol font and draw symbol to screen instead. But I just see "&" Typeface tf = Typeface.createFromAsset(m_context.getAssets(), "fonts/myFont.TTF" ); pnt.setTypeface(tf); m_canvas.drawText(symbolText,x, y, pnt); my font is in assets/fonts/myFont.TTF Not every font works with Android. It just silently fails. One course of action is to find
