扩展类ImageView（不是SVG）时出错

时间：2018-01-05 16:14:17

标签： android imageview android-imageview android-inflate

在AndroidStudio 3.0.1上

我的应用有一个RecyclerView，其中LinearLayout通过自定义适配器CardAdapter充气。在API＆gt; = 24上它可以正常工作，但在API＆lt; 24上它有一个致命的错误：

android.view.InflateException: Binary XML file line #0: Error inflating class ImageView
    at com.example.stavnoy.geronimosample.CardAdapter.onCreateViewHolder(CardAdapter.java:31)

（完整记录在底部）

我使用src作为ImageView，而不是SVG

这是我的通胀布局 - list_item：

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_margin="15dp"
    android:weightSum="8"
    android:gravity="center"
    android:background="@android:color/background_light">

    <ImageView
        style="@style/CardElement"
        android:padding="0dp"
        android:layout_margin="0dp"
        android:layout_weight="5"
        android:src="@drawable/unavailable"
        android:layout_gravity="fill_horizontal"
        android:contentDescription="Photo unavailable"/>
    <TextView
        style="@style/CardElement"
        android:textSize="24sp"
        android:text="Lorem Ipsum"
        android:textColor="@android:color/black"
        android:layout_gravity="center_vertical"/>
    <TextView
        style="@style/CardElement"
        android:layout_weight="1"
        android:textSize="16sp"
        android:text="Ipsum Lorem" />

    <View
        android:tag="line"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@android:color/black"/>

    <LinearLayout
        style="@style/CardElement"
        android:orientation="horizontal"
        android:gravity="end|center_vertical">
        <TextView
            style="@style/CardButton"
            android:text="@string/details_button_caps"
            android:textColor="@android:color/holo_blue_dark"
            android:onClick="details"/>
        <TextView
            style="@style/CardButton"
            android:text="@string/share_button_caps"
            android:textColor="@android:color/black"
            android:onClick="share"/>

    </LinearLayout>

</LinearLayout>

我的CardAdapter：

class CardAdapter extends RecyclerView.Adapter {
private final Context context;
private final JSONArray data;

CardAdapter(final JSONArray allCardsData, final Context context) {
    this.data = allCardsData;
    this.context = context;
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    return new CardViewHolder((LinearLayout) LayoutInflater.from(context).inflate(R.layout.list_item, parent, false));    //line 33
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    //more code
}

我的自定义样式（包括layout_width和layout_height）：

    <style name="CardButton">
    <item name="android:textSize">18sp</item>
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:gravity">end</item>
    <item name="android:paddingRight">4dp</item>
    <item name="android:paddingLeft">4dp</item>
    <item name="android:textAllCaps">true</item>
</style>

<style name="CardElement">
    <item name="android:layout_weight">1</item>
    <item name="android:layout_margin">10dp</item>
    <item name="android:paddingLeft">5dp</item>
    <item name="android:layout_height">0dp</item>
    <item name="android:layout_width">match_parent</item>
</style>

答案 0 :(得分：0)

根据添加的样式，我的猜测是（假设样式不是-v24）重复的属性可以在API 24+中接受，但不能在以前的版本中接受：

android:padding="0dp"
android:layout_margin="0dp"
android:layout_weight="5"

我会尝试从样式中删除它们并将其移动到没有明确显示它们的元素，或者仅为ImageView创建其他样式。

答案 1 :(得分：0)

Xavier Rubio Jansana建议使用可用于src的系统，这导致了问题：资源管理不善。 我将.jpg文件存储在drawable目录而不是mipmap目录中。它适用于直接使用的布局文件，但不适用于inflate()。我仍然不知道为什么API＆gt; = 24设法处理它。
