Question

我最近在一些java代码中添加了一个按钮进入我的程序，它可以像往常一样解析数据类型，我保存，构建和清理它。当我这样做时，我的所有Android ID和我的大多数XML表单都开始出错。

这是XML表单之一。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:background="@drawable/background">
    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="2" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"

            android:text="Armor Class Bonus" 
            android:textColor="#FFFF00"
            android:textAppearance="?android:attr/textAppearanceLarge">

        <TextView

            android:textColor="#FFFF00"
            android:textAppearance="?android:attr/textAppearanceLarge">
        </TextView>
        <TextView
            android:id="@+id/ACWeight"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:text="Armor Class Weight" 
            android:textColor="#FFFF00"
            android:textAppearance="?android:attr/textAppearanceLarge">

        <TextView

            android:textAppearance="?android:attr/textAppearanceLarge">
        </TextView>
        <Button
            android:id="@+id/bACDescriptionSave"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:text="Save" >
        </LinearLayout>
    </ScrollView>

</LinearLayout>

这是我当时正在处理的java类。

Answer 1

它不是valid XML你不是关闭按钮标签

将其更改为

<Button
            android:id="@+id/bACDescriptionSave"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:text="Save" >  </Button>    <-----------you forgot here
        </LinearLayout>

Answer 2

您必须关闭Button标记：

<Button
            android:id="@+id/bACDescriptionSave"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:text="Save" /> <-- add /

解析XML时出错：不匹配的标记/按钮无法解析为类型
