如何禁用材质设计片段导航在特定活动内的抽屉

我在我的应用程序中使用了片段导航抽屉和FloatingActionButton。点击FloatingActionButton将我带到新建活动。现在我添加了setDisplayHomeAsUpEnabled（true），它将我带到父活动。但在这个活动中，我仍然可以滑动Fragment Navigaion Drawer，当我点击抽屉项目应用程序崩溃时。我想在第二项活动中禁用碎片导航抽屉。我将如何做到这一点。这是我的代码。如何禁用材质设计片段导航在特定活动内的抽屉

MainActivity.java

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    mToolbar = (Toolbar) findViewById(R.id.toolbar); 

    setSupportActionBar(mToolbar); 
    getSupportActionBar().setDisplayShowHomeEnabled(true); 

    drawerFragment = (FragmentDrawer) 
      getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer); 
    drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout), mToolbar); 
    drawerFragment.setDrawerListener(this); 

    ImageView imageView = new ImageView(this); 
    imageView.setImageResource(R.mipmap.icon_launcher); 

    FloatingActionButton actionButton = new FloatingActionButton.Builder(this).setContentView(imageView).build(); 
    actionButton.setOnClickListener(this); 
} 

@Override

     return false; 
    } 

    @Override 
    public void onTouchEvent(RecyclerView rv, MotionEvent e) { 
    } 
} 

public interface FragmentDrawerListener { 
    public void onDrawerItemSelected(View view, int position); 
} 
}

AddTopicActivity.java

public class AddTopicFragment extends ActionBarActivity { 

private Toolbar mToolbar; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_ma); 
    setContentView(R.layout.activity_main); 

    mToolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(mToolbar); 
    getSupportActionBar().setHomeButtonEnabled(true); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

} 

}

我希望当这个活动开始时分段导航抽屉功能将完全禁用。我能够删除抽屉图标，但仍然当我从左侧抽屉滑入图片。

谢谢。

但为什么你选择导航的活动，同时项目创建？ –

对不起，我不明白你想说什么？ –

我看到你正在使用相同的布局文件** R.layout.activity_main **这两个活动..任何理由这样做？ – Droidwala

加入AddTopicActivity第二项活动。它会锁定刷卡

用于锁定

mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

解锁

mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);

我使用Fragment，FragmentDrawer，java类中显示的代码使用自定义的抽屉布局。并通过添加这些行应用程序崩溃。 –

可能'mDrawerLayout'为'null'你必须让'static'来访问其他活动 –

Ÿ我使mDrawerLayout静态，现在应用程序不崩溃但仍然可以访问 –
