For this example, you will create the AutoCompleteTextView so that it contains a list of the months of the year When a user types into the box, it will anticipate which month they are trying to enter Given that the AutoCompleteTextView will contain a list of the months, you need to create a list that can be assigned to the AutoCompleteTextView Create a string array and assign the month values to it:

Lists, Menus, and Other Views
The next snippet of code instantiates the two Buttons This is the same code you have used in previous chapters The only difference here from other code you have written is that you are calling two functions, changeOption and changeOption2, which have not been created yet
NOTE
Notice that you are passing the AutoCompleteTextView into the function calls You will need to create this parameter when you create the functions
final Button changeButton = (Button) findViewById(RidautoCompleteButton); changeButtonsetOnClickListener(new ButtonOnClickListener() { public void onClick(View v){ changeOption(textView); } }); final Button changeButton2 = (Button) findViewById(RidtextColorButton); changeButton2setOnClickListener(new ButtonOnClickListener() { public void onClick(View v){ changeOption2(textView); } });
The functions called by these Buttons will be used to change layout attributes on the AutoCompleteTextView The two attributes I have chosen to modify (using the Buttons) are the layout height and text color You are going to set up one of these Buttons to change the AutoCompleteTextView s layout height from 30 to 100 and back The other Button will change the color of the text within the View to red The function changeOption( ) will change the AutoCompleteTextView s layout height The code for this function is very simple:
public void changeOption(AutoCompleteTextView text){ if (textgetHeight()==100){ textsetHeight(30); } else{ textsetHeight(100); } }
What you are doing in this function is checking the current height of the AutoCompleteTextView If that height is 100, you set it to 30; otherwise you set it to 100

The changeOption2( ) function is just as easy:
public void changeOption2(AutoCompleteTextView text){ textsetTextColor(ColorRED); } }
This function simply sets the text color of the AutoCompleteTextView to ColorRED The value ColorRED is imported from the androidgraphicsColor package You can browse this package and change the color to any value; I selected RED so that it would stand out Your full autocompletejava file should now look like this:
package android_programmers_guideAndroidViews; import import import import import import import androidappActivity; androidosBundle; androidviewView; androidwidgetArrayAdapter; androidwidgetAutoCompleteTextView; androidwidgetButton; androidgraphicsColor;
public class AutoComplete extends Activity { @Override public void onCreate(Bundle icicle) { superonCreate(icicle); setContentView(Rlayoutautocomplete); ArrayAdapter<String> monthArray = new ArrayAdapter<String>(this, androidRlayoutsimple_list_item_1, Months); final AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(RidtestAutoComplete); textViewsetAdapter(monthArray); final Button changeButton = (Button) findViewById(RidautoCompleteButton); changeButtonsetOnClickListener(new ButtonOnClickListener() { public void onClick(View v){ changeOption(textView); } }); final Button changeButton2 = (Button) findViewById(RidtextColorButton);
