android.view.inflateException Android

我創建了一個java類和一個帶有圖像按鈕的佈局。當我設置內容視圖時，它會拋出運行時異常。android.view.inflateException Android

錯誤：

XML佈局：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/letters_bg" > 

    <ImageButton 
     android:id="@+id/imageButton1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentLeft="true" 
     android:layout_marginBottom="49dp" 
     android:src="@drawable/leftsignpost" /> 

</RelativeLayout>

的Java類代碼：

public class LettersScreenActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.letters_screen); // error is here 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

    } 
}

那麼是什麼問題？爲什麼會拋出運行時異常？

你檢查，如果你的圖形內容都OK？你清理了你的項目嗎？ – psykhi

是的，我已經清理了我的項目。 – zanky

我試過這個代碼...它真的做工精細...請檢查您的圖片和清單文件

在提供的代碼中沒有任何明顯的問題，應該運行？至少對我來說是這樣（當然，drawable是我的）。

檢查是否有適當的引用資源letters_bg和leftsignpost。這些必須在res/drawable之下。清理項目。嘗試提供更長的堆棧跟蹤。

我已經檢查過，但它仍然拋出同樣的例外。 – zanky

在堆棧跟蹤結束時，它必須是另一個異常（原因），這是實際原因。我們需要了解這個例外。您發佈的堆棧跟蹤太短。 – h22

我編輯了我的問題。 – zanky
