我想创建一个带操作栏的列表菜单，因此我无法使用ListActivity。我创建了以下代码，但在测试时没有显示列表：
public class MainActivity extends AppCompatActivity {
ListView RecordList;
ArrayList<String> sectionArr;
ListAdapter adapter1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getRecordSet(); //A procedure to get list from SQLite DB (tested ok)
adapter1 = new CardListAdapter(this, sectionArr);
RecordList = (ListView)findViewById(R.id.listSet);
RecordList.setAdapter(adapter1);
RecordList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id)
{
}
});
}...
在我的自定义适配器中，代码为：
class CustomAdapter extends ArrayAdapter<String>{
public CustomAdapter(Context context, ArrayList<String> strArr) {
super(context, R.layout.custom_row, strArr);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
int[] colors = new int[] {0x30A1B6AE, 0x30ECE7E7};
int colorPos = position % colors.length;
if (rowView==null) {
LayoutInflater inflator = LayoutInflater.from(getContext());
rowView = inflator.inflate(R.layout.custom_row, parent, false);
rowView.setBackgroundColor(colors[colorPos]);
}
String singleMenuItem = getItem(position);
TextView menuItemText = (TextView) rowView.findViewById(R.id.idItem);
menuItemText.setText(singleMenuItem);
return rowView;
}
@Override
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
}
}
布局是：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.lusterview.studycards.MainActivity" >
<ListView
android:id="@+id/listSet"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_margin="10dp"
android:cacheColorHint="@android:color/black" >
</ListView>
请告知。
提前致谢。
