如果你想使用一种习俗观点,就有可能这样做。这样做的方法是,在 Java建立一个习俗观类别,扩大某些基观成分类别。

例如,我的许多申请都使用习俗美术。彩虹类只能转移一种 frame子或一种不同于违约行为的wi子。

我给我的习惯,是扩大基本美术堂——

package com.testing.whatever;

public class CustomGallery extends Gallery {
    //CODE OVERRIDES HERE
}

然后,在我的《刑法》中,该法典与你已经拥有的相似之处——

<com.testing.whatever.CustomGallery android:layout_width="fill_parent" android:layout_height="fill_parent" />

我怀疑你重犯了错误,因为你登上了编码。电池组。电池意见或意见在你java档案中的错误位置。
