AutoCompleteTextView数据绑定
首先,在布局文件main.xml中添加AutoCompleteTextView组件,代码如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<AutoCompleteTextView
android:id="@+id/auto_complete"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
然后在MainActivity.java中定义需要绑定的数据,并将其绑定到组件上。代码如下:
public class MainActivity extends Activity {
// 定义一组需要绑定的数据
private static final String[] COUNTRIES = new String[] { "China", "Russia",
"Germany", "USA", "Chinal", "Germany1", "China12" };
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 进行数据绑定
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.易做图_dropdown_item_1line, COUNTRIES);
AutoCompleteTextView textview = (AutoCompleteTextView) findViewById(R.id.auto_complete);
textview.setAdapter(adapter);
}
}
效果图如下:
