的LinearLayout achartengine图滚动型中不显示 [英] LinearLayout achartengine Chart not displaying in ScrollView

问题描述

我试图创建一个滚动视图内achartengine的图表，但它不会显示！它只是显示一个黑色的屏幕，但不会崩溃或任何东西。问题是，如果我只是我的标签更改图表显示就好了。而在我的Java code我有renderer.setInScroll（真正的）;在图表渲染器。这是我的XML的问题？

I'm trying to create an achartengine chart within a scrollview but it won't display! It just shows a black screen, but doesn't crash or anything. The thing is if I just change my tag to the chart displays just fine. And in my Java code I do have renderer.setInScroll(true); for the charts renderer. Is this an issue with my xml?

下面是我的xml：

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

    <LinearLayout
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    android:orientation="vertical" >

        <LinearLayout
        android:id="@+id/trendchart"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" />
    </LinearLayout>

</ScrollView>

（目前在滚动型的唯一的事情就是图我计划添加更多的元素，使滚动必要的，我只是希望它显示第一）

(Currently the only thing in the ScrollView is the chart I plan to add more elements to make scrolling necessary, I just want it to display first)

另外我试图使用和不缠绕的LinearLayout既显示它与它是相同的结果。

Also I have tried to display it both with and without the wrapping linearlayout and it is the same result.

推荐答案

根据滚动视图，你必须插入

Under the scrollview you have to insert

android:fillViewport="true"
