android - 使用 Android Studio 0.4.0 的渲染问题

Question

在使用 Eclipse 一段时间后，我最近决定试用 Android Studio。我的主要 Activity xml 在 Eclipse 上呈现正常，但 Studio 似乎有问题。它在预览窗口中报告此问题:渲染问题 java.lang.StackOverflowError 将堆栈复制到剪贴板。

剪贴板的部分内容(全部>70K字符)为:

实际的xml代码是:

<?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="match_parent"
    tools:context=".MainActivity" >

<TextView
    android:id="@+id/currentPosition"
    style="@style/ScreenFont_Normal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:background="#F7F7E6"
    android:textColor="#8B8B8B"
    android:text="@string/curr_loca" />

<fragment 
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/currentPosition"
    class="com.google.android.gms.maps.SupportMapFragment"
    tools:layout="@layout/activity_main"/>

<ProgressBar
    android:id="@+id/progressBar1"
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true" />

</RelativeLayout> 

虽然这不会影响 .apk 文件的构建和创建，但我仍然想利用 Studio 的酷炫图形 UI 编辑功能。

任何帮助将不胜感激

干杯

Answer 1

从 fragment 中的 XML 中删除以下行:

tools:layout="@layout/activity_main"/>

原因:在 Android Studio 中，当您处理包含 fragment 的 XML 文档时，您会看到一个编辑单独布局的选项。 选择编辑父布局的选项后，上面的这一行将插入到代码中。干杯
