当我从字符串数组更改语言时，应用程序崩溃

Question

我正在尝试更改下拉式适配器视图中的语言，该视图使用旋转adpater从字符串数组资源获取数据。我根据区域设置创建了两个不同的Strings.xml（一个用于法语，一个用于英语），但当我切换到法语并单击旋转器下拉菜单时，应用程序崩溃了。

下面是默认值目录中的Strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">Color Picker</string>
    <string name="new_name">Color Name</string>
    <string name="select">Please select a color</string>
    <string name="color1">Cyan</string>
    <string name="color2">Gray</string>
    <string name="color3">Yellow</string>
    <string name="color4">Green</string>
    <string name="color5">Magenta</string>
    <string name="color6">Blue</string>
    <string name="color7">White</string>
    <string name="color8">Red</string>
    <string-array name="color_array">
        <item>@string/select</item>
        <item>@string/color1</item>
        <item>@string/color2</item>
        <item>@string/color3</item>
        <item>G@string/color4</item>
        <item>@string/color5</item>
        <item>@string/color6</item>
        <item>@string/color7</item>
        <item>@string/color8</item>
    </string-array>
</resources>

下面是values-fr-rFR目录中的strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">Palette de Couleurs</string>
    <string name="new_name">Couleur Choisie</string>
    <string name="select">Choisissez une Couleur</string>
    <string name="color1">Marron</string>
    <string name="color2">Gris</string>
    <string name="color3">Jaune</string>
    <string name="color4">Vert</string>
    <string name="color5">Magenta</string>
    <string name="color6">Bleu</string>
    <string name="color7">Blanc</string>
    <string name="color8">Rouge</string>
    <string-array name="color_array">
        <item>@string/select</item>
        <item>string/color1</item>
        <item>string/color2</item>
        <item>string/color3</item>
        <item>string/color4</item>
        <item>string/color5</item>
        <item>string/color6</item>
        <item>string/color7</item>
        <item>string/color8</item>
    </string-array>
</resources>

这是自定义适配器中返回自定义视图的代码（视图是简单的文本视图）

private fun getCustomView(position: Int, convertView: View?, parent: ViewGroup): View {
    val view: View
    val txt: String = getItem(position).toString()

    if (convertView == null) {
        view = inflater.inflate(resID, parent, false)

        val textView = view.findViewById<TextView>(R.id.txtTextView)
        //txt = list[position]
        textView.text = txt

        setBackground(view, txt, position)

    } else {
        view = convertView
        setBackground(view, txt, position)
    }

    return view
}

这是我的主要activity--除了法语之外，所有的东西都是英语的--当你点击旋转器上的下拉菜单并选择一种颜色时，一个新的activity就会启动并显示所选的颜色。当语言为法语时，点击旋转器会自动崩溃应用程序，而没有选择颜色的机会

val colors = resources.getStringArray(R.array.color_array)

val spinner = findViewById<Spinner>(R.id.colorSpinner)

spinner?.adapter = (CustomAdapter(this, R.layout.activity_dropdown, colors))

spinner.onItemSelectedListener = object : OnItemSelectedListener{
    override fun onNothingSelected(parent: AdapterView<*>?) {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }

    override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
        val color = parent!!.getItemAtPosition(position).toString()

        if(position == 0){
            return
        }else{
            val intent = Intent(this@MainActivity, NewActivity::class.java).apply {
                putExtra(COLOR_MESSAGE, color)
            }
            startActivity(intent)
        }
    }
}

}

下面是应用程序崩溃的堆栈跟踪

Answer 1

可能只是错别字。在英语语言中的color_array中，有一个在@前面有G的项

<item>G@string/color4</item>

在法语中，你忘记了几个项目中的@before'string'。

<item>string/color1</item>
<item>string/color2</item>
<item>string/color3</item>
<item>string/color4</item>
<item>string/color5</item>
<item>string/color6</item>
<item>string/color7</item>
<item>string/color8</item>

试着修理一下，看看是否有用。
