Question

I am new to Android Environment.I have to display Toast message box using the String[] value.But the Toast message Syntax cannot accept the String[] value.How can i display message the String[] value by Using Toast.The Toast can accept the CharSequence only.how can i change the String[] value into CharSequence?

Here i am using this code to display String[] Value:

 public static String[] sysid1;
 sysid1= PerformCommand(inCmd,"","",m_SystemID, m_Username,m_Password,m_Data);
 Toast toast=Toast.makeText(EpicClub.this,sysid1,Toast.LENGTH_SHORT);
toast.show()

Answer 1

Convert the String array to string using :

String sysid1String = Arrays.toString(sysid1)  

and then pass sysid1String it as argument to Toast.makeText

like this

Toast.makeText(getApplicationContext(),sysid1String ,Toast.LENGTH_SHORT).show();

Answer 2

You can output a String using a Toast. What you're trying to do is output an Array of Strings.

Depending on what you want to output either concatenate the Strings, or select the String at your required index and select that for output.

Answer 3

you have to use like:

String[] sysid1 = {"a","b"};  

Toast.makeText(MainActivity.this, ""+Arrays.toString(sysid1), Toast.LENGTH_SHORT).show(); 

Answer 4

Suppose you have array of strings as below. You can use the array index to display the toast.

 public static String[] sysid1={"hello","hi"};
 Toast toast=Toast.makeText(this,sysid1[0],Toast.LENGTH_SHORT);
 toast.show(); 

Instead of string array you can use a arraylist

   ArrayList<String> al = new ArrayList<String>();
   al.add("hello");
   al.add("hi");
   Toast toast=Toast.makeText(this,al.get(0),Toast.LENGTH_SHORT);// use the index to get the string
   toast.show();
