對於下面發佈的佈局,我試圖遍歷整個佈局並顯示佈局中每個視圖的ID。 我試過貼在下面的代碼與方法如何獲取視圖的唯一ID
vg.getId()
,但它顯示的每個視圖相同的ID在佈局
請你告訴我怎麼去每個視圖的唯一ID佈局
輸出:
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
07-02 14:48:25.383 32647-32647/com.example.alteenos.test_traversethroughaview_1 I/ActMain: vg.getId() :2131427422
辣油牛逼:

代碼:
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;
}
