我最近在Android Spinner的{​​{1}}方法中夸大了getView()项时，从Android 4.2设备收到了这个奇怪的错误：

ArrayAdapter

这是项目布局的XML：

这就是崩溃的路线：

<!-- 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>

那么，这里有什么问题？ Android Studio没有向我发出任何警告，应用程序编译并在我测试过的所有设备上运行正常......

2 个答案:

答案 0 :(得分：9)

问题在于 // SpinnerAdapter.java @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = View.inflate(getContext(), RESOURCE, null); <-- Crash } ... } 将被分配一种颜色，而不是android:tint=""所选择的选择器。

直接使用其值@android:color/tertiary_text_light或通过资源值en #808080将有效colors.xml。

答案 1 :(得分：1)

ImageView的色调是在Android API 21中引入的。如果要在API 21以下使用它，则可以使用android.support.v7.widget.AppCompatImageView；如果您在XML中声明该色调为选择器，则应替换“ android：tint ”和xml中的“ app：tint”

这里是一个例子：

<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" />
