我有一个自定义对话框，它扩展了 Dialog 类和一个简单的自定义布局，如下所示：

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@android:drawable/list_selector_background"
    >


<TextView
        android:id="@+id/text_view"
        android:layout_width="fill_parent"
        android:layout_height="50dp"
        android:gravity="center_vertical"
        android:paddingLeft="10dp"
        android:background="@color/transparent"
        android:textColor="@color/black"
        android:textSize="16sp"
        android:focusable="true"/>

我的问题是，当像附件图像中选择一行时，轨迹球使文本不可见。

在此处输入图像描述

list_selector_background 代码来自 Android，如下所示：

<item android:state_window_focused="false" android:drawable="@color/transparent" />

<!-- Even though these two point to the same resource, have two states so the drawable will invalidate itself when coming out of pressed state. -->
<item android:state_focused="true"  android:state_enabled="false" android:state_pressed="true" android:drawable="@drawable/list_selector_background_disabled" />
<item android:state_focused="true"  android:state_enabled="false"                              android:drawable="@drawable/list_selector_background_disabled" />
<item android:state_focused="true"                                android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" />
<item android:state_focused="false"                               android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" />
<item android:state_focused="true"                                                             android:drawable="@drawable/list_selector_background_focus" />

我的 ListView xml 代码是这样的：

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:drawSelectorOnTop="true"
          android:background="@color/white"
          android:cacheColorHint="@color/transparent">

</ListView>

我在 AlertDialog（来自 Android 的那个）上看到它工作正常。我应该怎么做才能解决这个问题？

谢谢

试试这个：从这一行中删除“android”文本。像;

android:background="@drawable/list_selector_background"

在列表视图中添加

android:cacheColorHint="@android:color/transparent"
android:drawSelectorOnTop="false"
android:listSelector="@android:color/transparent"
android:fadingEdge="none"

这对我有用
