Procedure for using the AutoCompleteTextView Control

The AutoCompleteTextView function is similar to the prompt that is close to the input information when Baidu or Google inputs information in the search bar. The result is an editable text view. A prompt is displayed after you enter the information. The prompt list is displayed in a drop-down menu, from which you can select one to complete the input. The prompt list is the data obtained from a data adapter.

Follow these steps:

Step 1: define controls in the layout File

 
 

  
  
<AutoCompleteTextView  
  
  
 
  
  
        android:id="@+id/actv" 
  
  
 
  
  
        android:layout_width="fill_parent" 
  
  
 
  
  
        android:layout_height="wrap_content" 
  
  
 
  
  
/> 
 
 

Step 2: reference in Activity

 
 

  
  
AutoCompleteTextView actv = (AutoCompleteTextView) findViewById(R.id.actv); 
 
 

Step 3: Create an adapter to save data

 
 

  
  
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
  
  
 
  
  
ndroid.R.layout.simple_dropdown_item_1line,new String[] {"English", "Hebrew", "Hindi", "German" }); 
 
 

Step 4: Associate the adapter with AutoCompleteTextView

 
 

  
  
actv.setAdapter(adapter);
