android.content.res.Resources $ NotFoundException：無法找到資源ID＃0x7d0

Question

當我嘗試在framelayout中加載片段時，應用程序崩潰並在log cat中顯示「資源未找到異常」。 當應用程序進行服務調用並嘗試多次加載片段時，我收到異常。

我已經在Google上搜索了這個問題，但沒有一篇文章或答案能幫助我。

代碼：

final FrameLayout frame = new FrameLayout(context); 
    frame.setId((i+1000)); // since frame layout added at runtime in loop i have added iteration value with 1000 to get unique id. 
final Fragment newFragment = new Fragment() 
mContext.getFragmentManager().beginTransaction().add((i +1000) ,newFragment).commitAllowingStateLoss(); 

能否請你幫我解決這個問題。

這裏的問題不在於兩個不同的服務正在運行，因此你會崩潰。

你的例外很清楚說明了ResourceNotFoundException。這意味着framelayout不是用給定的id創建的。

所以請找我下面的代碼可以解決你的問題：

FragmentManager fragmentManager = getFragmentManager(); 
FragmentTransaction fragmentTransaction; 
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER); 

for(int i=0;i<size();i++){ 
    FrameLayout layoutMain = new FrameLayout(this); 
    layoutMain.setId(Utils.generateViewId()); 
    layoutMain.setLayoutParams(params); 

    fragmentTransaction = fragmentManager.beginTransaction(); 
    Fragment newFragment = new Fragment() 
    fragmentTransaction.add(layoutMain.getId(), newFragment, "HELLO"); 
    fragmentTransaction.commit(); 
} 

因此，IDS的建立將搭載Android只有17歲以上的API版本來完成。 解決方法更低版本低於：

public class Utils{ 
    private static final AtomicInteger sNextGeneratedId = new AtomicInteger(1); 

    public static int generateViewId() { 
     if (Build.VERSION.SDK_INT < 17) { 
      for (;;) { 
       final int result = sNextGeneratedId.get(); 
       // aapt-generated IDs have the high byte nonzero; clamp to the range under that. 
       int newValue = result + 1; 
       if (newValue > 0x00FFFFFF) { 
        newValue = 1; // Roll over to 1, not 0. 
     } 
       if (sNextGeneratedId.compareAndSet(result, newValue)) { 
        return result; 
       } 
      } 
     } else { 
      return View.generateViewId(); 
     } 
    } 
}
