Question

How do i have an AutoComplete selection based on alphabetic instead of fixed switch cases? The situation is, everything working except when i input keyword with “B” showing Badrul as first suggestion but when clicked it will still refer to the first switch cases which is opening up Adidas.class instead of Badrul.class

Please help, i am new in this. Is AutoComplete suitable for my requirement?

public class Search extends Activity
{
    public void onCreate(Bundle savedInstanceSate)
    {
        super.onCreate(savedInstanceSate);
        setContentView(R.layout.searchshop);

        AutoCompleteTextView autoComplete = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, shops);
        autoComplete.setAdapter(adapter); 
        autoComplete.setThreshold(1);
        autoComplete.setOnItemClickListener(new OnItemClickListener()
        {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) 
        {
            switch(position)
            {
            case 0:
                startActivity(new Intent(Search.this, Adidas.class));
                break;
            case 1:
                startActivity(new Intent(Search.this, Affin.class));
                break;
            case 2:
                startActivity(new Intent(Search.this, AlamArt.class));
                break;
            case 3:
                startActivity(new Intent(Search.this, Badrul.class));
                break;
            }
        }
        });     
    }
    static final String[] shops = new String[]
            {
                "Adidas", "Affin Bank", "Alam Art Gallery", "Badrul"
            };
}

This is obvious behavior as you are referring to the position of the suggestion at current time,so it would be differed according to what user types in. For achieving what you want,You need to change your code according to this:

public class Search extends Activity
{
    public void onCreate(Bundle savedInstanceSate)
    {
        super.onCreate(savedInstanceSate);
        setContentView(R.layout.searchshop);

        final AutoCompleteTextView autoComplete = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, shops);
        autoComplete.setAdapter(adapter); 
        autoComplete.setThreshold(1);
        autoComplete.setOnItemClickListener(new OnItemClickListener(){

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
                int index=999;
                for(int i=0;i<shops.length;i++)
                {
                    if(autoComplete.getText().toString().trim().equals(shops[i]))
                    {
                         index=i;
                         break;
                    }               
                }
                switch(index)
                {
                    case 0:
                         startActivity(new Intent(Search.this, Adidas.class));
                         break;
                    case 1:
                         startActivity(new Intent(Search.this, Affin.class));
                         break;
                    case 2:
                         startActivity(new Intent(Search.this, AlamArt.class));
                         break;
                    case 3:
                         startActivity(new Intent(Search.this, Badrul.class));
                         break;
                    default:
                         Toast.makeText(Search.this, "Invalid Selection", Toast.LENGTH_SHORT).show();
               }
           }
       });     
    }
    static final String[] shops = new String[]
    {
          "Adidas", "Affin Bank", "Alam Art Gallery", "Badrul"
    };
}
