我正在編寫一個Android應用程序,它與API示例一樣使用AutoCompleteTextView。問題在於我的文本太長,需要在下拉菜單時換行。我有一個自定義list_item.xml,但只顯示一行文本。如果與微調器一起使用,則list_item.xml佈局將包裝爲2行,但不包含AutoCompleteTextView。Android:使AutoCompleteTextView下拉列表換行至2行或更多
main.java
public class main extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete_country);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES);
textView.setAdapter(adapter);
}
static final String[] COUNTRIES = new String[] {
"This is the first line that is too long and it needs to wrap content",
"Albania", "Algeria", "American Samoa", "Andorra",
"This is a second line that also needs to wrap its content",
"Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium"
};
}
main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Country" />
<AutoCompleteTextView android:id="@+id/autocomplete_country"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"/>
</LinearLayout>
list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp"
android:textColor="#000"
>
</TextView>
爲什麼不能得到答案? – viplezer 2013-12-07 14:48:29
