錯誤膨脹按鈕

我有一個按鈕的佈局就可以了：錯誤膨脹按鈕

<Button 
    android:id="@+id/myapp_new" 
    style="@style/header_button" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentRight="true" 
    android:layout_centerVertical="true" 
    android:background="@drawable/header_button" 
    android:gravity="center" 
    android:text="new" />

該按鈕的風格被定義爲這樣的：

<style name="header_button" parent="@android:style/TextAppearance.Medium"> 
    <item name="android:textColor">@color/white</item> 
    <item name="android:textSize">16sp</item> 
</style>

當我打開我的手機上這個活動，我收到崩潰。

setContentView(R.layout.layout_tags);

如果我刪除android:background參數，崩潰消失：設置內容視圖行中的崩潰發生。我不明白，因爲drawable包含在應用程序中，並且在其他設備（包括模擬器）上正常工作。

我會在此主題底部發布錯誤日誌。

正如我所說的，這次崩潰只發生在我的一個設備上（我有2 +模擬器）。它發生在運行Android 2.2.1的舊手機上，但不會出現在我的模擬器（運行2.2）或我的新手機（運行4.1.2）上。

最大的區別是我的設備與崩潰具有較低的屏幕分辨率。我在ldpi文件夾中沒有圖像。我的印象是Android會自動從下一個文件夾中選擇圖片。此外，我有很多其他圖像加載得很好。

我真的很想將我的應用程序發佈到Google Play商店，但這讓我難以忍受。我擔心這個崩潰會發生在其他人的手機上，儘管我只能在一臺設備上重現它。有沒有人有任何想法？我迷路了。

也許'android：id =「@ + id/new」'導致問題，因爲new是java中的保留關鍵字 –

對不起，id實際上並不是「新」。我改變了它，因爲它包含我的應用程序的名稱（例如：myapp_new）。崩潰與設置背景有關。 – Andrew

您是否使用StateListDrawable作爲背景？你可以發佈嗎？ – brillenheini

的StackOverflowError例外，讓我覺得，你header_button背景依賴於自身，所以它的遞歸加載相同的文件，直到它死亡。

這是問題所在。我的按鈕的圖像是'header_button.png'，並且引用它的可繪製XML被稱爲'header_button.xml'。我改變了PNG的名稱，並解決了問題。 – Andrew

太深了。虛無主義者甚至。 –
