Question

I am new so forgive my primitive question, I am really not getting this. I am simply creating this array on my main activity while doing a tutorial and I get an error

package com.TaskReminder;

import android.R.string;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class ReminderListActivity extends ListActivity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.reminder_list);
    string[] items = new string[]{"aa","bb"};
    ArrayAdapter<string> adapter = new ArrayAdapter<string>(this,R.layout.reminder_row,R.id.text1,items);
    setListAdapter(adapter);


}

and the error on my string array is :

Multiple markers at this line
– Line breakpoint:ReminderListActivity [line: 14] –
onCreate(Bundle)

– Type mismatch: cannot convert from String to R.string

what’s exactly happening here?

Answer 1

Easy fix, the String type needs to be capitalized.

string[] items = new string[]{"aa","bb"};
ArrayAdapter<string> adapter = new ArrayAdapter<string>(this,R.layout.reminder_row,R.id.text1,items);

Becomes:

String[] items = new String[]{"aa","bb"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.reminder_row,R.id.text1,items);

@gt_ebuddy is right as well, remove this line:

import android.R.string;

Using Ctrl+Shift+O is the simplest way to import classes automatically, but it sometimes leads you astray when it tries to import anything from your package’s R file.
