这个问题在这里已有答案：
Introduction
我正在创建一个Android应用程序 . 它包含一个导航抽屉 .
My Problem
在我的应用程序中，我使用onclick事件启用相对布局的可见性 . 在onclick事件之后，相对布局变得可见 .
现在问题是，在启用相对布局“导航抽屉”的可见性之前，工作完美 .
但是在视图可见后，当我点击抽屉上的任何菜单项时，导航抽屉开始缩回 . 但在启用视图之前，导航抽屉菜单项会完美响应
我无法弄清楚问题所在 . 我使用了 mDrawerLayout.bringToFront(); mDrawerLayout.requestLayout(); 但没有实现解决方案

在上面的代码中，ID为offlineLayout的布局在启用visibilty后创建了上述问题 .
启用布局可见性的代码：
public void showOfflineDialog(boolean isOffline) {
RelativeLayout offlineLayout = (RelativeLayout) findViewById(R.id.offlineLayout);
if (isOffline)
{
offlineLayout.setVisibility(View.VISIBLE);
mDrawerLayout.bringToFront();
mDrawerLayout.requestLayout();
}
else
{
mDrawerLayout.bringToFront();
mDrawerLayout.requestLayout();
offlineLayout.setVisibility(View.GONE);
}
}
启用offlinelayout后，导航抽屉不响应点击次数..简单地回退 .
CodeBlock the initialise Navigation Drawer::
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerFragment = (FragmentDrawer)
getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
drawerFragment.setDrawerListener(this);
方法处理Nav Drawer中项目的OnClick事件
@Override
public void onDrawerItemSelected(View view, int position) {
switch (position) {
case 0:
Intent intent = new Intent(Map_Activity.this, YourTripsActivity_.class);
startActivity(intent);
break;
case 1:
Intent earnings = new Intent(Map_Activity.this, EarningActivity_.class);
startActivity(earnings);
break;
case 2:
Intent summary = new Intent(Map_Activity.this, EarningActivity_.class);
startActivity(summary);
break;
case 3:
Intent help = new Intent(Map_Activity.this, Help_activity.class);
startActivity(help);
break;
case 4:
logout();
break;
default:
break;
}
}
上面的代码在显示offlineLayout之前完全响应，但在显示offlineLayout后无法正常工作

我努力解决这个问题，但我找不到任何解决方案 . 请帮我 .
