achartengine - 对视图增加外部ImageButtons变焦旁边的图表引起奇怪的UI行为 [英] achartengine - adding External ImageButtons for zoom on view next to chart causes strange UI behavior

问题描述

我想对我的图表视图顶部的视图按钮。

I wanted to have Button on the view on the top of my chart view.

问题：

当我preSS按钮图表视图的克隆在$ P $后面出现挤pssed button.It是有只有一秒钟，然后消失。再看打印屏幕...

When I press the Button the clone of chart view appears squeezed at the back of pressed button.It is there for only one second and then disappears. Look at the print screen...

没有任何人有一个线索，为什么出现这种情况？

Does anybody have a clue why this happens?

我附加虚拟源$ C ​​$ C：

I'm attaching dummy source code:

布局（main.xml中）：

layout (main.xml):

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

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

    <LinearLayout
        android:id="@+id/layXzoom"
        android:layout_width="wrap_content"

        android:layout_alignParentRight="true"
        android:orientation="horizontal"

        <Button

推荐答案

托尼也张贴在aChartEngine问题跟踪它已被回答（在一定程度上）这个问题。

toni has also posted this question on the aChartEngine issues tracker where it has been answered (to a degree).

链接到问题：的http：// code.google.com / p / achartengine /问题/细节？ID = 171

解决方案总结：

renderer.setInScroll(true);

这似乎采取伪影的照顾。

which seems to take care of the artifacting.
