android 自动匹配文本 AutoCompleteTextView /MultiAutoCompleteTextView

//AutoComplete java示例

public class MainActivity extends Activity {
private AutoCompleteTextView acTextView;
private String[] res = {"beijing1","beijing2","beijing3",          //提示资源
"shanghai1","shanghai2"};

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
/**
* 1、初始化控件
* 2、需要一个适配器，ArrayAdapter
* 3、初始化数据源---匹配文本框输入的内容
* 4、将adapter与AutoCompleteTextView绑定
*/

acTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
ArrayAdapter adapter = new ArrayAdapter<>(this,
android.R.layout.simple_list_item_1, res);    //3个参数：上下文，布局，资源
acTextView.setAdapter(adapter);    //绑定
}
}

//MultiAutoCompleteTextView  的java示例

public class MainActivity extends Activity {
private MultiAutoCompleteTextView macTextView;
private String[] res = {"beijing1","beijing2","beijing3",
"shanghai1","shanghai2"};

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
/**
* 1、初始化控件
* 2、需要一个适配器，ArrayAdapter
* 3、初始化数据源---匹配文本框输入的内容
* 4、将adapter与AutoCompleteTextView绑定
* 5、设置分割符
*/

macTextView = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView1);
ArrayAdapter adapter = new ArrayAdapter<>(this,
android.R.layout.simple_list_item_1, res);
macTextView.setAdapter(adapter);
//设置以 逗号为分割符
macTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
//在系统自定义中分隔符只有 逗号，其他需要自设
}
