我正在编写一个使用 AutoCompleteTextView 的 Android 应用程序,就像 API 示例一样。问题在于我的文本太长,在下拉列表出现时需要换行。我有一个自定义的 list_item.xml,但只显示一行文本。如果与 spinner 一起使用,list_item.xml 布局会换行为 2 行,但与 AutoCompleteTextView 不兼容。
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"
};
}
主要的.xml文件
