我有一个FrameLayout，我以编程方式在其上绘制一些东西（FullScreen）。这意味着我在>>> def foo(arg):
def bar():
arg += 1
return arg
return bar
>>>
>>> foo(0)() # this will raise an error
Traceback (most recent call last):
File "<pyshell#76>", line 1, in <module>
foo(0)() # this will raise an error
File "<pyshell#74>", line 3, in bar
arg += 1
UnboundLocalError: local variable 'arg' referenced before assignment
>>>
>>> def foo(arg):
def bar():
nonlocal arg
arg += 1
return arg
return bar
>>> foo(0)() # this will work
1
>>>
文件中添加的每个元素都将重叠。所以我想我可以像这样添加xml：
Fragment但我无法找到将片段置于某个位置的方法（在本例中为Center Bottom）。我也无法在 FrameLayout frameLayout = (FrameLayout) findViewById(R.id.frameLayout);
CustomPlayView customPlayView = new CustomPlayView(getApplicationContext());
frameLayout.addView(customPlayView);
FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTrans = fragMan.beginTransaction();
Fragment myFrag = new PlayerInfoFragment();
fragTrans.add(R.id.fragment,myFrag,"playerInfoFragment");
fragTrans.commit();
文件中定义Fragment，因为它会与我使用的xml重叠。
有什么想法吗？
