我有一個自定義ListView與複選框和3個TextViews。這裏是我的列表項佈局：Android自定義ListView與複選框和更改背景顏色
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listviewitem_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<CheckBox
android:id="@+id/faxCheckBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:focusableInTouchMode="false" />
<LinearLayout android:orientation="horizontal"
android:id="@+id/faxbox_item_first_row"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/faxCheckBox"
android:paddingTop="8dp"
android:paddingLeft="8dp"
android:paddingRight="8dp">
<TextView android:id="@+id/fax_number_textView"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:lines="1"
android:ellipsize="start"
android:textSize="12sp"
android:paddingRight="5dp"/>
<TextView android:id="@+id/fax_send_date_textView"
android:layout_width="wrap_content"
android:layout_weight="0"
android:layout_height="wrap_content"
android:textSize="9sp"/>
</LinearLayout>
<TextView android:id="@+id/more_fax_info_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="9sp"
android:textColor="@color/gray"
android:layout_toRightOf="@id/faxCheckBox"
android:layout_below="@id/faxbox_item_first_row"
android:paddingLeft="8dp"/>
</RelativeLayout>
我也爲ListView自定義arrayadapter：
private class MyAdapter extends ArrayAdapter<Order> {
private ArrayList<Order> mOrders;
private Context mContext;
private int mResourceId;
public MyAdapter(Context context, int resourceId, ArrayList<Order> orders) {
super(context, resourceId, orders);
this.mContext = context;
this.mOrders = orders;
this.mResourceId = resourceId;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(mResourceId, parent, false);
}
final Order order = mOrders.get(position);
if (order != null) {
TextView sender = (TextView)view.findViewById(R.id.number_textView);
TextView date = (TextView)view.findViewById(R.id.send_date_textView);
TextView moreInfo = (TextView)view.findViewById(R.id.more_info_textView);
CheckBox checkBox = (CheckBox)view.findViewById(R.id.checkBox);
final int itemPosition = position;
final RelativeLayout rowLayout = (RelativeLayout)view.findViewById(R.id.listviewitem_layout);
view.setTag(order.getId());
if (sender != null) {
sender.setText(order.getSender());
}
rowLayout.setBackgroundResource(R.drawable.listview_item_selector);
if (mSelectedIds.contains(order.getId())) {
rowLayout.setBackgroundColor(Color.parseColor("#9CD7EF"));
}
if (date != null) {
date.setText(Utils.getStringDateForBox(order.getSendDate(), mContext));
}
if (moreInfo != null) {
moreInfo.setText(getResources().getQuantityString(R.plurals.number_of_pages, order.getPages(), order.getPages()));
}
if (checkBox != null) {
checkBox.setTag(order.getId());
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (mSelectedIds.contains(buttonView.getTag()) == true) {
if (isChecked == false) {
mSelectedIds.remove(buttonView.getTag());
}
} else {
if (isChecked) {
mSelectedIds.add((Long) buttonView.getTag());
}
}
showHideActionMode();
setActionModeTitle();
mListView.setItemChecked(position, true);
}
});
if (mSelectedIds.contains(order.getId())) {
checkBox.setChecked(true);
} else {
checkBox.setChecked(false);
}
}
}
return view;
}
}
listview_item_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true"
android:drawable="@color/blue" />
<item android:state_pressed="true"
android:drawable="@color/blue" />
<item android:state_selected="true"
android:state_activated="true"
android:drawable="@color/light_blue" />
<item android:state_activated="true"
android:drawable="@color/light_blue" />
<item android:state_selected="true"
android:drawable="@color/light_blue" />
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false"
android:drawable="@android:color/white" />
<item android:drawable="@android:color/transparent" />
</selector>
的問題是，如果我按一個行，然後它將背景顏色更改爲藍色，但沒有複選框，checbox始終保持橙色背景顏色。我該如何改變它？ 也許我應該一切都不同？我最喜歡的是ICS上的gmail應用程序。
