在Android中，如何在不禁用onClick颜色的情况下更改listView的背景颜色？(In Android how do you change the background color of a listView without disabling the onClick color?)

我有一个listView，我需要提供背景颜色来掩盖活动的背景图像。我希望在单元格的基础上执行此操作，以便如果listView没有到达屏幕的底部，则背景颜色将显示没有更多列表项目要显示的位置。另外，我应该提一下，我将这个ListView放在ImageViews之间，使用：

android:layout_above

和

android:layout_below

因此，对于较小的屏幕，ListView将在较低的ImageView顶部正确滚动，而不是在它的前面或后面。但是对于较大的屏幕，我希望当没有更多的列表项显示时，活动的背景图像可见。

我一直在寻找选择器，这可能是我正在寻找的东西，但据我所知，选择器的颜色将显示在listView的背景颜色后面。

这就是我现在正在尝试的。关于如何完成我想要的任何建议？

item.xml

下面的activity_main.xml

这是我的list_item.xml

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/gray" > <ImageView android:id="@+id/img" android:layout_width="30dp" android:layout_height="30dp" android:layout_marginRight="15dp" android:layout_marginTop="20dp" android:layout_alignParentRight="true" /> <TextView android:id="@+id/txt" android:layout_width="wrap_content" android:layout_height="50dp" android:layout_marginTop="17dp" android:layout_marginLeft="15dp" android:textSize="23sp" /> </RelativeLayout&t;

这将创建正确的颜色，如下所示，但onClick颜色不会显示它应该。

I have a listView that I need to give a background color to cover up the activity's background image. I would prefer to do this on a cell basis so that if the listView doesn't reach the bottom of the screen, the background color will show where there are no more list items to display. Also, I should mention that I have this ListView positioned between to ImageViews using:

android:layout_above

and

android:layout_below

So that for smaller screens, the ListView will scroll properly on top of the lower ImageView rather than in front of or behind it. For larger screens however, I'd like the activity's background image to be visible when there are no more list items to display.

I've been looking around at selectors and that might be what I'm looking for, but from what I'm told the selector's color will display behind the background color for the listView.

This is what I'm trying now. Any suggestions on how to accomplish what I'm trying to?

item.xml

activity_main.xml below

and this is my list_item.xml

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/gray" > <ImageView android:id="@+id/img" android:layout_width="30dp" android:layout_height="30dp" android:layout_marginRight="15dp" android:layout_marginTop="20dp" android:layout_alignParentRight="true" /> <TextView android:id="@+id/txt" android:layout_width="wrap_content" android:layout_height="50dp" android:layout_marginTop="17dp" android:layout_marginLeft="15dp" android:textSize="23sp" /> </RelativeLayout>

Which creates the correct colors as shown below, but the onClick color is not displaying as it should.
