当我使用模拟器运行我的项目时，它弹出了＃34;不幸的是项目停止了＃34;有致命的例外，任何人都可以看看我的项目并知道错误是什么？我得到了以下logcat错误：

Answer 1

一个解决方案是，您应首先用片段替换活动，然后将top和bottom值的参数传递给该片段。

这就像是

@Override
public void createMeme(String top, String bottom) 
        Fragment fragment = new BottomPictureFragment();
        Bundle args = new Bundle();
        args.putString("Top", top);
        args.putString("Bottom",bottom);
        fragment .setArguments(args);
        FragmentManager frgManager = getSupportFragmentManager().beginTransaction().replace(R.id.activity_main, fragment).commit();

执行此操作后，您可以在onCreateView（）中的BottomPictureFragment中获取参数，并从onCreateView（）调用setMeme（top，bottom）函数。
