Question

I am building an app that include the c++ programs. I just need to show the code as a text in my xml layout. I don’t want it to compile it or to do anything else with it. But every time i write the text it show error that you cant use strings like ‘<‘, ‘>’ or double inverted commas. Can you please help me out how i can use these strings in my text view.
Here is my xm layout.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<EditText
    android:id="@+id/program_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:inputType="textMultiLine"
    android:text="
       #include<iostream.h>
       #include<conio.h>
       void main()
       {
         int arr[n], i,j,n,temp;
         cout<<"How any elements you want to enter";
         cin>>n;
         cout<<"Enter array elements"
         for(i=0;i<n;i++)  
         cin>>a[i]
       }     " >

    <requestFocus />
</EditText>

Take a look to my response in this question. You shouldn’t include literal strings in your XML layout. It is much more recommended to store C code in files in assets folder, so you don’t need to modify them at all (it’s a waste of time and a source of errors). Just inflate a WebView widget with all the C code enclosed in <pre>[text read from file]</pre> tags and you will be able to show it perfectly OK and take advantage of scrolling and zoom for free.
