import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.MultiAutoCompleteTextView;

public class MainActivity extends AppCompatActivity {

    private AutoCompleteTextView mAutoCompleteTextView;
    private MultiAutoCompleteTextView mMultiAutoCompleteTextView;
    private String[] ceshi1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mAutoCompleteTextView=findViewById(R.id.autocomplete);
        mMultiAutoCompleteTextView=findViewById(R.id.multiautocomplete);
        ceshi1 = new String[]{"北京西站", "北京北站", "北京站", "北京南站", "北京大使馆",
                "北京故宫", "天津电视塔", "天津南站", "天津东站", "天津之眼", "天津劝业场","aaa","bbb",

        ArrayAdapter adapter=new ArrayAdapter(MainActivity.this,android.R.layout.simple_list_item_activated_1,ceshi1);
        mAutoCompleteTextView.setAdapter(adapter);
