[英]how to remove this error (android.content.res.Resources$NotFoundException: String resource ID #0xffffffff)
[英]Android messed up R.java unable to find resource ID #0xffffffff
我不小心在布局xml中將按鈕的ID設置為“ mybutton-1”。 當我在Android Studio中點擊“運行應用程序”時,它切換到R.java並出現錯誤
public static final int mybutton-1=0x7f0b00e1;
錯誤消息說有一個;
預期在-1之后。 所以我將布局xml中該按鈕的ID更改為“ myButton_a”,然后再次點擊運行應用。 這次我在mainActivity.java中遇到錯誤:
ArrayList<View> focusableViews = view.getFocusables(View.FOCUS_FORWARD);
for (int i = 0; i < focusableViews.size(); i++) {
View actualView = focusableViews.get(i);
String actualID = actualView.getResources().getResourceEntryName(actualView.getId()); // here
...
}
我查看了R.java,它按預期將我的更改更新為public static final int myButton_a=0x7f0b00e1;
這是堆棧跟蹤:

我怎么解決這個問題? 我讀到我必須手動設置ID,但是還有另一種方法嗎? 我不想再搞亂ID
如果您的視圖沒有ID,則getId()
將返回-1。 這樣就變成了0xffffffff。
看來你的focusableViews
不僅包含mybutton1, 但也有一些別人沒有的ID。 那就是問題所在。
