Question

当我尝试在framelayout中加载片段时，应用程序崩溃并在log cat中显示“资源未找到异常”。当应用程序进行服务调用并尝试多次加载片段时，我收到异常。

我已经搜索过这个问题，但这些帖子或答案都没有帮助我。

Logtrace：

代码：

 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();

这里的问题不在于正在运行的两个不同服务，因此您正在崩溃。

您的例外情况非常清楚地表明ResourceNotFoundException。这意味着不使用给定的id创建framelayout。

所以，请找到可以解决您问题的以下代码：

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的创建将由Android仅使用17及以上的API版本完成。下层版本的解决方法如下：

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();
        }
    }
}
