由 NumberFormatException 引起的 class ImageView 膨胀错误

Question

我最近在 Android 4.2 设备 ArrayAdapter 的 getView() 方法中对 Spinner 项目充气时收到这个奇怪的错误：

这是项目布局的XML：

<!-- item_autocomplete.xml -->
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="48dp"
    android:gravity="center_vertical"
    android:padding="8dp">

    <TextView
        android:id="@+id/item_autocomplete_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:textColor="@color/primaryColor"/>

    <ImageView
        android:id="@+id/item_autocomplete_img"
        android:layout_width="14dp"
        android:layout_height="14dp"
        android:layout_below="@id/item_autocomplete_title"
        android:padding="2dp"
        android:src="@drawable/ic_location_on_black_18dp"
        android:tint="@android:color/tertiary_text_light"/>

    <TextView
        android:id="@+id/item_autocomplete_subtitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/item_autocomplete_img"
        android:layout_toEndOf="@+id/item_autocomplete_img"
        android:layout_toRightOf="@+id/item_autocomplete_img"
        android:textColor="@android:color/tertiary_text_light"
        android:textSize="12sp"/>

</RelativeLayout>

这是它崩溃的地方：

    // SpinnerAdapter.java
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = View.inflate(getContext(), RESOURCE, null); <-- Crash
        }
        ...
    }

那么，这里出了什么问题？ Android Studio 没有向我发出任何警告，应用程序在我测试过的所有设备上编译和运行都很好...

Answer 1

问题只是要为 android:tint="" 分配颜色，而不是选择器，而 @android:color/tertiary_text_light 是。

直接使用其值 #808080 或通过资源值 en colors.xml 将起作用 @colors/gray_light。

Answer 2

ImageView的tint是在Android API 21中介绍的，如果想在API 21以下使用可以使用android.support.v7.widget.AppCompatImageView and如果您在 xml 中将色调声明为选择器，则应在 xml

中将 "android:tint" 替换为 "app:tint"

这是一个例子：

<android.support.v7.widget.AppCompatImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/btn_apply"
        app:tint="@color/button_selector" />
