Question

Each listView binding tutorial I checked but I have a strong confusion in the adapter section.
First see my code

ListView listView = (ListView) findViewById(R.id.mylist);
String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
  "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
  "Linux", "OS/2" };

// First paramenter - Context
// Second parameter - Layout for the row
// Third parameter - ID of the TextView to which the data is written
// Forth - the Array of data
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
  android.R.layout.simple_list_item_1, android.R.id.text1, values);

// Assign adapter to ListView
listView.setAdapter(adapter); 

See this line

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
      android.R.layout.simple_list_item_1, android.R.id.text1, values);

What is this? android.R.layout.simple_list_item_1 who says that we can refer to the listeView by R???

why??? Please help

Answer 1

instead of

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, values);

try using

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, values);

or use

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,R.id.theTextViewID, values);
