我有一个自定义SELECT FIRST 1 acbccccic FROM acbcc
WhERE (acbccscic=4 OR acbccscic=5) AND
acbccccic IN (SELECT acbcaccic FROM acbca WHERE acbcacage=116437)
ORDER BY acbccccic DESC
，其中每个元素都有一个图标和3个SELECT SUM(actdtmahi+actdtmahd+actdtmahv) AS saldo
FROM actdt
WHERE actdtcage=116437 AND actdtmrcb=0 AND
actdtccic IN (SELECT FIRST 1 acbccccic FROM acbcc
WHERE (acbccscic=4 OR acbccscic=5) AND
acbccccic IN (SELECT acbcaccic FROM acbca WHERE acbcacage=116437)
ORDER BY acbccccic DESC)
。我可以将背景更改为白色，但是现在单击文本时看不到动态效果。我的意思是触摸时呈灰色（波纹效果）。
这是ListView
TextView我的MainActivity中的方法 ListView mListView = findViewById(R.id.list_layout);
names = new ArrayList<>();
macs = new ArrayList<>();
adapter= new CompleteListAdapter(this, names, macs);
mListView.setAdapter(adapter);
adapter.notifyDataSetChanged();
CompleteListAdapter这是extends BaseAdapter
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = LayoutInflater.from(mContext).inflate(R.layout.two_line_icon, parent, false);
TextView text1 = (TextView) rowView.findViewById(R.id.text1);
TextView text2 = (TextView) rowView.findViewById(R.id.text2);
ImageView icon = (ImageView) rowView.findViewById(R.id.icon);
text1.setText(names.get(position));
text2.setText(macs.get(position));
return rowView;
}
这是main_activity.xml的单个条目：<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
