將片段更改爲RoboGuice片段？

我想在我的應用程序中使用RoboGuice。我的第一個嘗試是將簡單的片段更改爲RoboFragment。但該應用程序無法編譯了。這裏可能是什麼問題？將片段更改爲RoboGuice片段？

class MyFragment extends RoboFragment { 

     @InjectView(R.id.progress_bar) private static ProgressBar progressBar; 
    }

結果：

E/AndroidRuntime(1237): java.lang.RuntimeException: Unable to start activity 
ComponentInfo{path.to.MyApp}: android.view.InflateException: Binary XML file line #34: 
Error inflating class fragment 
.

/編輯：

我想我的問題是，進度條片段中我這樣做：

public static void setProgressBar(Activity parent, int visible) { 
    progressBar = (ProgressBar) parent.findViewById(R.id.progress_bar); 
}

這可能可能不適用於RoboGuice注射？

如果發佈包括所有異常的完整logcat輸出，我們可以嘗試找出哪一個是您應該修復的。 xml充氣行34中包含你的.fragment，logcat輸出中應該有片段顯示異常，告訴你片段中的哪一行包含錯誤。

你的堆棧跟蹤說

一十二月6日至10日：06：23.063：E/AndroidRuntime（676）：產生的原因： java.lang.IllegalArgumentException異常：MyActivity @ 412f8b38不似乎是一個RoboGuice上下文（instanceof RoboContext）

是您的活動RoboFragmentActivity？

上面做了編輯。可能是我使用父進程欄是注射問題？ – membersound

您將一個progressBar注入到Fragment中，因此您有一個ProgressBar。然後，您要將其更改爲不在視圖中的活動的ProgressBar。使用您注入到Fragment中的ProgressBar更容易。還有你的堆棧跟蹤說「06-10 12：06：23.063：E/AndroidRuntime（676）：引起：java.lang.IllegalArgumentException：MyActivity @ 412f8b38似乎不是RoboGuice上下文（instanceof RoboContext）」是你的Activity一個RoboFragmentActivity？ – Christine

爲什麼「progressBar」字段是靜態的？

從任何活動內部訪問進度條，因爲幾個應該能夠啓動並取消相同的進度條。 – membersound

這是一個不好的做法，你應該重新考慮你的設計 –

什麼是不好的做法？或者我怎麼能做得更好？ – membersound
