Question

由於我不是專家，我無法識別下面的錯誤是logcat。 我正在調用另一個頁面onclick按鈕。 在加載另一個頁面時，我收到錯誤

setContentView(R.layout.searchm); 

下面是源代碼和locgcat

Logcat如下

Answer 1

我認為您在布局XML中使用類CustomAutoCompleteTextView （可能從AutoCompleteTextView擴展），而不使用完整的類名（帶包）。 在這種情況下，Android會自動嘗試在android.view包中找到這個類 - 但在你的情況下它不能這樣做（因為那里沒有calss）。 最有可能的是，你的XML有這樣的東西：

<CustomAutoCompleteTextView ...>

相反，對於自定義類，您需要使用包指定完整的類名 - 因此將其更改為

<com.your.package.CustomAutoCompleteTextView ...>

Answer 2

在您的xml文件中

<CustomAutoCompleteTextView

                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                   />

用。。。來代替

<YoupPckageNameSpecifiedInYourCustomview.CustomAutoCompleteTextView

                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                       />

Answer 3

我認為你應該嘗試引用類CustomAutoCompleteTextView，它應該是AutoCompleteTextView

“沒找到類”android.view.CustomAutoCompleteTextView“”

你需要在你自己的應用程序中定義這個類，或者在android用戶中定義

Answer 4

如果您在使用Android Api運行的模擬器上運行項目，則使用帶有Google-API的模擬器運行/測試您的項目。
