android：1.5中的ScrollView不起作用

标签： android scrollview

我的一个布局在1.6+上运行完美但在1.5上抛出错误并导致使用“强制关闭”关闭应用程序。布局包含RelativeLayout作为父级，ScrollView包含RelativeLayout作为子和imagevite，textview，edittext，子relativeleayout中的按钮。这是xml文件：

<?xml version="1.0" encoding="utf-8"?>

错误指向LoginDialog类中的setContentView（）行。 谁能说出什么阻止它出现在1.5。

由于

2 个答案:

答案 0 :(得分：0)

第一个例外是FileNotFoundException。检查文件res/drawable/scrollbar_handle_vertical.9.png是否存在。

答案 1 :(得分：0)

解决方案：

错误所在的图像，即“0x7f020005”，这是一个.png图像。 1.5无法识别drawable-hdpi中的png图像或任何，它在/ drawable文件夹中查找。我在/ res中创建了一个可绘制的文件夹，并将png图像复制到它，屏幕显示出来。但是由于屏幕尺寸小，一切都是一个接一个。我在ScrollView中尝试使用android：scrollbars =“vertical | horizo​​ntal”属性，但它只能垂直滚动，水平滚动不起作用。现在怎么处理这个问题（滚动水平）？
