Answer 1

You are passing Description as string [] tp a tvdescription text view but text view only support to string . That was an issue.

So, first you need to correct that process. For example, you need to identify which data need to show in the text view from the string array that you used.

OR,

If you want to show string array on text view you should set that string array to string. For that, you could try below solutions,

Solution 1

String[] Description = { "first", "second", "third"}
// Print as [first, second, third ]
tvdescription.setText(Arrays.toString(Description));   

// Print as first, second, third 
tvdescription.setText(Arrays.toString(Description).replaceAll("\\[|\\]", ""));

Solution 2

String[] Description = { "first", "second", "third"}

StringBuilder descriptionText = new StringBuilder();
for (String s: Description) {
    descriptionText.append(s);
    descriptionText.append(" ");
}

tvdescription.setText(descriptionText.toString().trim());
