  您可以简单地使用autocompleteTextview的setText方法

  String[] country={"France ","USA","Bangladesh","Canada","Other"};
   autocompleteTextView.setText(country[0]);
  

  你可以轻松使用setText，它非常适合我 .

  试试这个代码......

  ###XML:
      <AutoCompleteTextView
      android:id="@+id/autoCompleteTextView1"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:ems="10"
      android:text="France" 
      >
  
      <requestFocus />
      </AutoCompleteTextView>
  
  ###MainActivity:
      public class MainActivity extends Activity {
          AutoCompleteTextView act;
          String[] country={"France ","USA","Bangladesh","Canada","Other"};
          ArrayAdapter<String> adapter;
  
          protected void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.activity_main);
  
              act=(AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);
              adapter=new ArrayAdapter<String>(getApplicationContext(),  
              android.R.layout.simple_spinner_item, country);
              act.setAdapter(adapter);
              act.setThreshold(1);
          }
      }
