[英]Iterate through each widget declared in XML and perform an action in java and android development
对于 android 开发,假设我在 XML 中声明了几个 ImageButtons
在 my.java 文件中,我该怎么做:
foreach (ImageButton with attribute="xyz") {do this}
只需遍历视图容器的所有后代并为满足某些条件的每个视图执行操作:
private void iterateImages(ViewGroup group) {
for (int i = 0, n = group.getChildCount(); i < n; ++i) {
View child = group.getChildAt(i);
if (child instanceof ViewGroup) {
iterateImages((ViewGroup)child);
} else if (child instanceof ImageView) {
ImageView image = (ImageView)child;
if ( /* attribute"xyz" */ ) {
// do this
}
}
}
}
