在Eclipse可视化编辑器定制的Andr​​oid浏览 [英] Custom Android Views in Eclipse Visual Editor

问题描述

在我的应用程序，我经常依靠于自行设计的看法，如下面的例子。

In my applications, I often rely on custom build views, such as in the following example.

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

<TextView 
 style="@style/CardTitle" 
 android:id="@+id/card_title"
 android:layout_height="wrap_content" 
 android:layout_width="fill_parent"      
 />  

<com.whiterabbit.cards.ui.AspectRatioImageView
    android:id="@+id/card_picture"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:layout_marginLeft="30dip"
    android:layout_marginRight="30dip"       
    android:src="@drawable/boss"
    />



<ListView 
    android:id="@+id/card_properties" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"

/>

现在的问题是，我不知道该怎么是否会直到我在一个真正的设备或仿真器上运行它正确地显示。此外，如果我发现了一些错误，我将不得不对其执行修改并再次部署应用程序，以查看是否变化和预期的一样工作。

The problem is, I don't know how if it will be displayed correctly until I run it on a real device or on the emulator. Moreover, if I found something wrong I would have to perform changes on it and deploy the app again to see if the changes worked as you expected.

这可能是一个漫长而枯燥的过程，特别是如果应用程序需要一定的相互作用去要检查活动。

This can be a long and boring process, especially if the application requires some interaction to get to the activity you want to check.

使用可视化编辑器不能正常工作，因为它无法加载自定义视图。

Using the visual editor doesn't work as it cannot load the custom view.

有另一种方式，以检查视图显示没有在整个应用程序中运行？

Is there another way to check how views are displayed without running across the whole application?

推荐答案

您可以在您的自定义视图做到这一点：

You can do this in your Custom View:

if(!isInEditMode()){
   // Your custom code that is not letting the Visual Editor draw properly
   // i.e. thread spawning or other things in the constructor
}

<一个href="http://developer.android.com/reference/android/view/View.html#isInEditMode%28%29">http://developer.android.com/reference/android/view/View.html#isInEditMode()

这允许您隐藏code从ADT插件XML阅读器，希望显示你的布局！

This allows you to hide code from the ADT Plugin XML Viewer and hopefully display you a layout!

View.isInEditMode（）

View.isInEditMode()

Indicates whether this View is currently in edit mode. A View is usually in edit mode when displayed within a developer tool. For instance, if this View is being drawn by a visual user interface builder, this method should return true. Subclasses should check the return value of this method to provide different behaviors if their normal behavior might interfere with the host environment. For instance: the class spawns a thread in its constructor, the drawing code relies on device-specific features, etc. This method is usually checked in the drawing code of custom widgets.
