对于下面发布的布局，我试图遍历整个布局并显示布局中每个视图的ID。 我试过贴在下面的代码与方法如何获取视图的唯一ID
vg.getId()
，但它显示的每个视图相同的ID在布局
请你告诉我怎么去每个视图的唯一ID布局
输出：
ew_1 I/ActMain: vg.getId() :2131427422
07-02 14:48:25.383 32647-32647/com.example.alteenos.test_traversethroughaview_1 I/ActMain: vg.getId() :2131427422
07-02 14:48:25.383 32647-32647/com.example.alteenos.test_traversethroughaview_1 I/ActMain: vg.getId() :2131427422

代码：
private int countViews(ViewGroup vg) {
int childCount = vg.getChildCount();
for (int i = 0; i < childCount; i++) {
Log.i(TAG, "vg.getId() :" + vg.getId());
//if (vg.getChildAt(i) instanceof ViewGroup) {
//childCount += countViews((ViewGroup) vg.getChildAt(i));
//}
}
return childCount;
}
