GridView 子级不显示焦点

在 Android 应用程序中，我有一个 GridView 保存由适配器创建的 TextView。在这些 TextView 中，我添加了一个具有三种状态（按下、选择和默认）的图标。我使用 android:listSelector="#00000000" 删除了 GridView 的默认选择器，我希望显示图标的选定状态。但是，尽管按下状态有效（即当按下 TextView 时，会显示图标的按下版本），但选择的状态却不起作用。

我已经尝试过这些技巧（在网络上的不同地方找到），但它也不起作用：

设置

android:descendantFocusability="afterDescendants"

或
```
android:drawSelectorOnTop="true"
```
或（在 TextView 中）
```
android:duplicateParentState="true" />
```

如果我将 TextView 设置为可聚焦，它就会独立于 GridView 获得焦点（即，单击它不会调用 GridView onClick 方法...

）图标在 xml 文件中定义如下：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_focused="true"
    android:state_pressed="true"
    android:drawable="@drawable/ic_flag_bg_pressed"/>
  <item android:state_focused="false"
    android:state_pressed="true"
    android:drawable="@drawable/ic_flag_bg_pressed"/>
  <item android:state_focused="true"
    android:drawable="@drawable/ic_flag_bg_selected"/>
  <item android:state_focused="false"
    android:state_pressed="false"
    android:drawable="@drawable/ic_flag_bg_default"/>
</selector>

有没有办法告诉 GridView 将焦点状态传递给其子级？

原文

In an android app, I have a GridView holding TextView created by an adapter. In those TextView I add an icon which has three states (pressed, selected and default.)
I removed the default selector of the GridView with android:listSelector="#00000000" and I would like the selected state of the icon to display instead. But although the pressed state works (ie when the TextView is pressed, the pressed version of the icons is shown) the seleted doesn't.

I've tried those tricks (found at different places on the web) but it didn't work either:

setting

android:descendantFocusability="afterDescendants"

or
```
android:drawSelectorOnTop="true"
```
or (in the TextViews)
```
android:duplicateParentState="true" />
```

And if I set the TextView to be focusable, it gets focus independently of the GridView (ie, clicking on it doesn't call the GridView onClick method...)

The icon is defined in a xml file like this:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_focused="true"
    android:state_pressed="true"
    android:drawable="@drawable/ic_flag_bg_pressed"/>
  <item android:state_focused="false"
    android:state_pressed="true"
    android:drawable="@drawable/ic_flag_bg_pressed"/>
  <item android:state_focused="true"
    android:drawable="@drawable/ic_flag_bg_selected"/>
  <item android:state_focused="false"
    android:state_pressed="false"
    android:drawable="@drawable/ic_flag_bg_default"/>
</selector>

Is there a way to tell the GridView to pass the focused state to its children ?
