Caused by: java.lang.NumberFormatException: For input string: "?2130969371"

题记报错。

上结论："?2130969371" ，即：”？attr/sudScrollIndicator“，是因为sudScrollIndicator自定义属性主题未给定值引起。

在AS工程引入setupdesign和setupcompat时，简单写了个主AppCompatActivity，引用了一个被GlifLayout包裹的布局文件。

如下：

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.setupdesign.GlifLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context=".MainActivity"><ImageViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:layout_gravity="center"android:src="@drawable/ic_circle" /><TextViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:layout_gravity="center_horizontal"android:text="@string/sud_next_button_label"/></LinearLayout>
</com.google.android.setupdesign.GlifLayout>

然后运行，发生如下错误。

关键性的报错如下（见截图）：

Caused by: java.lang.NumberFormatException: For input string: "?2130969371"

根据如上调用栈，一直找到View的5874行，如下代码：

    public View(Context context, @Nullable AttributeSet attrs, int defStyleAttr, int defStyleRes) {this(context);mSourceLayoutId = Resources.getAttributeSetSourceResId(attrs);final TypedArray a = context.obtainStyledAttributes(attrs, com.android.internal.R.styleable.View, defStyleAttr, defStyleRes);retrieveExplicitStyle(context.getTheme(), attrs);saveAttributeDataForStyleable(context, com.android.internal.R.styleable.View, attrs, a,defStyleAttr, defStyleRes);//......// Set default values.viewFlagValues |= FOCUSABLE_AUTO;viewFlagMasks |= FOCUSABLE_AUTO;final int N = a.getIndexCount();for (int i = 0; i < N; i++) {int attr = a.getIndex(i);switch (attr) {
//......case R.styleable.View_scrollIndicators:final int scrollIndicators =(a.getInt(attr, 0) << SCROLL_INDICATORS_TO_PFLAGS3_LSHIFT)  // Line 5874& SCROLL_INDICATORS_PFLAG3_MASK;if (scrollIndicators != 0) {mPrivateFlags3 |= scrollIndicators;initializeScrollIndicators = true;}break;

至此，基本肯定是：R.styleable.View_scrollIndicators的问题。

看布局文件sud_glif_template_content.xml（隶属于引入的Setupdesign公共组件里边定义）。

    <!-- Ignore UnusedAttribute: scrollIndicators is new in M. Default to no indicators in olderversions. --><com.google.android.setupdesign.view.BottomScrollViewandroid:id="@+id/sud_scroll_view"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"android:fillViewport="true"android:scrollIndicators="?attr/sudScrollIndicators"tools:ignore="UnusedAttribute">

在这里给了个符号占位引用，并未直接给出值，值靠给定的Theme主题来定义。

 <!-- Values copied from frameworks/base/core/res/res/values/attrs.xml --><attr name="sudScrollIndicators"><!-- No scroll indicators are displayed. --><flag name="none" value="0x00" /><!-- Displays top scroll indicator when view can be scrolled up. --><flag name="top" value="0x01" /><!-- Displays bottom scroll indicator when vew can be scrolled down. --><flag name="bottom" value="0x02" /><!-- Displays left scroll indicator when vew can be scrolled left. --><flag name="left" value="0x04" /><!-- Displays right scroll indicator when vew can be scrolled right. --><flag name="right" value="0x08" /><!-- Displays right scroll indicator when vew can be scrolled in thestart direction. --><flag name="start" value="0x10" /><!-- Displays right scroll indicator when vew can be scrolled in theend direction. --><flag name="end" value="0x20" /></attr>

BottomScrollView是setupdesign里边定义的组件，且其主题在base主题里边有给出值，如果子Theme不重载覆盖，保持默认即可。

总共有4个Theme设置了sudScrollIndicators，其中一个就是

SudBaseThemeGlif.Light

。

sudScrollviewIndicators

再看自定义且应用到GlifLayout对应的测试activity主题。

发现其实我们并未直接继承自相关主题，而且取了个相同名字的主题，并未完全覆盖自定义的符号应用（例如：？attr/sudScrollIndicators）。

    <style name="SudBaseThemeGlif.Light" parent="Theme.AppCompat.Light.NoActionBar"><item name="android:indeterminateTint">?attr/colorControlActivated</item><!-- Specify the indeterminateTintMode to work around a bug in Lollipop --><item name="android:indeterminateTintMode">src_in</item><item name="android:navigationBarColor">@android:color/black</item><item name="android:statusBarColor">@android:color/transparent</item><item name="android:textAppearanceListItemSmall">?attr/textAppearanceListItemSmall</item></style>

至此，

原因水落石出，

1.错误拷贝了setupdesign里边的主题来测试，覆盖了引入子模块的baseTheme设值，且为完全覆盖自定义符号属性值的给定。

2.Caused by: java.lang.NumberFormatException: For input string: "?2130969371" 这句log, 后边的数字就是sudScrollIndicator自定义属性占位符的id, 见如下：

./app/build/generated/not_namespaced_r_class_sources/debug/r/com/google/android/setupdesign/R.java:695:        public static final int sudScrollIndicators = 0x7f04031b;
./app/build/intermediates/symbols/debug/R.txt:858:int attr sudScrollIndicators 0x7f04031b
./app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:410:    <attr name="sudScrollIndicators">
./app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:3756:        <item name="sudScrollIndicators">bottom</item>
./app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:3780:        <item name="sudScrollIndicators">bottom</item>
./app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:4097:        <item name="sudScrollIndicators">top|bottom</item>
./app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:4116:        <item name="sudScrollIndicators">top|bottom</item>

（2130969371的16进制表示即：0x7f04031b, 所以当它找不到值时，？attr/sudScrollIndicator 即解析为：？2130969371）。
