在我的应用程序中,我使用的是自动完成文本。当用户键入 t 时,它显示三个,两个,五十个,但我想显示两个,三个而不是五十个。谁能帮我解决这个问题。
String search[] = {"one","two","three","four","five","six","seven","fifty"};
ArrayAdapter<String> adp= new ArrayAdapter<String>(this,R.layout.searchtext, search);
search_item.setThreshold(1);
search_item.setAdapter(adp);
最佳答案
我认为您不必创建自定义适配器。您想要的默认功能。检查这个
在这里我有像这样的数组:
private static final String[] COUNTRIES = new String[] { "Belgium",
"France", "France_", "Italy", "Germany", "Spain","abcf","FFa","FFb","bFF","aFF" };
当我搜索ff时,它只给我
2("FFa","FFb")
建议而不是4("FFa","FFb","bFF","aFF")
我已经在ActionBar中使用过此功能。您也可以在布局中使用它。因为它在ActionBar中具有自定义布局。
public class TestActivity extends Activity {
/** Called when the activity is first created. */
private static final String[] COUNTRIES = new String[] { "Belgium",
"France", "France_", "Italy", "Germany", "Spain","abcf","FFa","FFb","bFF","aFF" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowCustomEnabled(true);
// actionBar.setDisplayShowTitleEnabled(false);
// actionBar.setIcon(R.drawable.ic_action_search);
LayoutInflater inflator = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.test, null);
actionBar.setCustomView(v);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, COUNTRIES);
AutoCompleteTextView textView = (AutoCompleteTextView) v
.findViewById(R.id.editText1);
textView.setAdapter(adapter);
}
}
