使用AutoCompleteTextView和MultiAutoCompleteTextView自动提示

package org.ourunix.android.autocompletetextviewtest; import android.app.Activity; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.AutoCompleteTextView; import android.widget.MultiAutoCompleteTextView; //android提供了自动提示功能的textview，按照自带的文档和api demo可以写几行代码就可以实现此功能。但默认的thresh为2，所以默认情况下你必须输入两个或者两个以上的字符，才会有自动提示功能，否则AutoCompleteTextView是不会有任何提示的。当然你可以通过setThresh来设置至少输入几个字符后才会有提示，也可以在xml里设置。 AutoCompleteTextView会把你所有的字符串当做子串去做匹配， 而MultiAutoCompleteTextView会根据你提供tokenizer来分解你已经输入的字符串，并对符合条件的最后几个字符当做子串去做自动提示。 // //例如做了一下设置，MultiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); // public class AutoCompleteTextViewActivity extends Activity { private AutoCompleteTextView mAutoCompleteTextView; private MultiAutoCompleteTextView mMultiAutoCompleteTextView; private static final String[] autoString = { "ni", "nihao", "nihaoa", "nihaohuaia" }; private ArrayAdapter<String> adapter; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, autoString); mAutoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.myAutoCompleteTextView); mAutoCompleteTextView.setAdapter(adapter); mMultiAutoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.myMultiAutoCompleteTextView); mMultiAutoCompleteTextView.setAdapter(adapter); mMultiAutoCompleteTextView .setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); } }
