android - How to set TextView Dynamically left of paraent? -


यहाँ मेरा कोड है मुझे त्रुटि पैरामीटर शून्य है 

  viewDynamic = new TextView (getApplicationContext) ()); रिलेटिव लेआउट रिलेक्टिव लेआउट = (रिलेटिव लेआउट) ढूंढिए वीवीआईबीआईआईडी (आरआईड। सेलेबल); रिलेटिव लेआउट। लेआउटपारों पैराम्स = (रिलेटिव लेआउट। लेआउटपारम) viewDynamic.getLayoutParams (); params.addRule (RelativeLayout.ALIGN_PARENT_LEFT); params.addRule (RelativeLayout.ALIGN_PARENT_BOTTOM); params.addRule (RelativeLayout.ABOVE, userEditTxt.getId ()); ViewDynamic.setLayoutParams (नया लेआउटप्रर्म (लेआउट पर्म। WRAP_CONTENT, लेआउट पैरा। WRAP_CONTENT)); viewDynamic.setText (userEditTxt.getText ()); viewDynamic.setTextColor (Color.RED); viewDynamic.setTextScaleX (2); viewDynamic.setTextSize (20); viewDynamic.setPadding (10, 10, 10, 10); //viewDynamic.setVisibility(View.GONE); relativeLayout.addView (viewDynamic, पैरामीटर);    
 
 
 अगर आपने कोई भी पैंट कंटेनर को दृश्य नहीं जोड़ा है, या सेटलेआउटपारों को बुलाया गया है मैन्युअल रूप से, तब getLayoutParams () रिक्त लौटेगा।  
 आप को कॉल करें  viewDynamic.setLayoutParams (नया लेआउटप्रर्म (लेआउटप्रर्म। WRAP_CONTENT, लेआउट पैरा। WRAP_CONTENT));   पहले < / Strong> आप कॉल  viewDynamic.getLayoutParams (); , या एक कंटेनर में दृश्य जोड़ते हैं, इसलिए देखने के लिए LayoutParams जेनरेट किए जाएंगे।  
 मेरा सुझाव है कि आप अपने दृश्य को जोड़ते हैं जैसे यह:  <पूर्व>  दृश्य = डायनामिक = नया टेक्स्टव्यू (getApplicationContext ()); रिलेटिव लेआउट रिलेक्टिव लेआउट = (रिलेटिव लेआउट) ढूंढिए वीवीआईबीआईआईडी (आरआईड। सेलेबल); रिलेटिव लेआउट। लेआउटपाराम पैराम्स = नए लेआउट पैरा (लेआउट पर्म। WRAP_CONTENT, लेआउट पैरा। WRAP_CONTENT) पैराम्स.एडआरयूएल (रिलेटिव लेआउट। ALIGN_PARENT_LEFT); params.addRule (RelativeLayout.ALIGN_PARENT_BOTTOM); params.addRule (RelativeLayout.ABOVE, userEditTxt.getId ()); viewDynamic.setText (userEditTxt.getText ()); viewDynamic.setTextColor (Color.RED); viewDynamic.setTextScaleX (2); viewDynamic.setTextSize (20); viewDynamic.setPadding (10, 10, 10, 10); RelativeLayout.addView (व्यू डायनामिक, पैराम्स); // आप यहां अपने व्यू में पैरामीटर देते हैं

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
