本文介绍了一个使用 Android MultiAutoCompleteTextView 的示例应用，演示了如何设置自动完成文本视图并自定义提示列表，同时展示了如何集成 FloatingActionButton 和 Snackbar 以增强用户体验。

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    private MultiAutoCompleteTextView nametext;
    private String[] res = {
            "beibi","baby","beijing","beiping","beihai",
            "beihaidao","beipei","babala"
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        nametext = (MultiAutoCompleteTextView)findViewById(R.id.name_text);
        ArrayAdapter <String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,res);
        nametext.setAdapter(adapter);
        nametext.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());



        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}
