java - RuntimeException和InflateException:二进制XML文件的第7行..后跟ClassCastException

关于此问题有多个问题，但是我所读过的所有修补程序似乎都没有起作用。

似乎无效的修复：

Fix 1: Android - InflateException: Binary XML file line #7

Fix 2: InflateException Binary XML file at line #7: Error inflating class fragment

问题描述：

我正在尝试将SliderView合并到我的玻璃器皿中。 SliderView可用作自定义加载屏幕。

1. Link I found-2. Google Review Team Proposed Link

我目前正在使用第一个链接。

在我的应用程序中，我调用SearchActivity.java来完成一些事情。我已经注释了大多数代码以查看问题，并且看来问题首先出现在这里：

protected void onCreate(Bundle bundle) {

        super.onCreate(bundle);
        setContentView(R.layout.activity_main);
}

这是可以在我的activity_main.xml中找到的：位于我的res / layout /中：

<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="match_parent"
    android:background="@android:color/black">

<!-- The line right under is line number 7 -->
    <com.google.android.glass.sample.apidemo.card.SliderView
        android:id="@+id/indeterm_slider"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true" />


    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:contentDescription="@string/banner_150"
        android:src="@drawable/websurg_icon_white_150" />

</RelativeLayout>

是的，我的SliderView位于我的com.google.android.glass.sample.apidemo.card包中。
是的，我的SliderView确实具有三个不同的必需构造函数。

public SliderView(Context paramContext) {
    this(paramContext, null);
}

public SliderView(Context paramContext, AttributeSet paramAttributeSet) {
    this(paramContext, paramAttributeSet, 0);
}

public SliderView(Context paramContext, AttributeSet paramAttributeSet, int paramInt) {
    super(paramContext, paramAttributeSet, paramInt);
    LayoutInflater.from(getContext()).inflate(R.layout.slider, this);
    this.slider = findViewById(R.id.slider_control);
    this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterm_slider));
    hideSlider(false);
    hideIndeterminateSlider(false);
}

我遇到两个具体问题，那就是：


  java.lang.RuntimeException：无法启动活动
  ComponentInfo {com.google.android.glass.sample.apidement / com.google.android.glass.sample.apidemeo.card.SearchActivity}：


和


  android.view.InflateException：二进制XML文件第7行：错误
  充气课
  com.google.android.glass.sample.apidemo.card.SliderView

所以我的问题是，是什么导致这些错误？我需要进行哪些更改才能使其正常工作？

更新：

LayoutInflater.from(getContext()).inflate(R.layout.slider, this);
        this.slider = findViewById(R.id.slider_control);
        this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterm_slider));

这是默认的res / layout / slider xml：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="@dimen/slider_bar_height" >

    <View
        android:id="@id/slider_control"
        android:layout_width="0.0px"
        android:layout_height="@dimen/slider_bar_height"
        android:background="@android:color/white" />

    <ImageView
        android:id="@id/indeterminate_slider"
        android:layout_width="fill_parent"
        android:layout_height="@dimen/slider_bar_height"
        android:background="@drawable/slider_indeterminate" />

</FrameLayout>

最佳答案

更新：
解决方案如下：

在SliderView.java构造函数（public SliderView(Context paramContext, AttributeSet paramAttributeSet, int paramInt)）中：

更改：

this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterm_slider));

至：

this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterminate_slider));

在您的slide.xml中（位于res / layout /中）：

更改：

<ImageView
        android:id="@id/indeterminate_slider" [...] />

至：

<ImageView
    android:id="@+id/indeterminate_slider" [...] />

主要问题是让SliderView.java指向正确的ID。由于尚未完成，因此您收到了InflateException。解决此问题后，您将获得ClassCastException。这来自您的slide.xml没有+

indeterm_slider是SliderView，并且您要转换为ImageView。之所以得到InflateException，是因为由于该ClassCastException而无法创建视图
