问题
I tried to follow this answer, with the main idea is to override the setContentView in the BaseActivity, the activity that will be extended by all activity so only BaseActivity will have the navigation drawer.
However, my navigation is never shown (even in BaseActivity) after i tried to implement the answer. This is what i did :
This is the navigation drawer's xml :
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Listview to display slider menu -->
<ListView
android:id="@+id/list_slidermenu"
android:layout_width="120dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/list_background"
android:choiceMode="singleChoice"
android:divider="@color/list_divider"
android:dividerHeight="1dp"
android:listSelector="@drawable/list_selector" />
</android.support.v4.widget.DrawerLayout>
This is my overrided setContentView (in BaseActivity) :
@Override
public void setContentView(int layoutResID) {
// TODO Auto-generated method stub
mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); // Your base layout here
actContent= (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);
//listLayout = (LinearLayout) mDrawerLayout.findViewById(R.id.listLayout);
getLayoutInflater().inflate(layoutResID, actContent, true);
//getLayoutInflater().inflate(layoutResID, listLayout, true);
super.setContentView(layoutResID);
}
And this is my onCreate on BaseActivity, note that i use getLayoutInflater().inflate instead of setContentView :
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
//getSupportActionBar().setDisplayShowHomeEnabled(false);
//getSupportActionBar().setDisplayShowCustomEnabled(true);
// enabling action bar app icon and behaving it as toggle button
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
//mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null);
//mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.list_slidermenu);
navDrawerItems = new ArrayList<NavDrawerItem>();
// adding nav drawer items to array
// Home
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
// Find People
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
// Photos
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
// Communities, Will add a counter here
navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));
// Pages
navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
// What's hot, We will add a counter here
navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));
// Recycle the typed array
navMenuIcons.recycle();
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
// setting the nav drawer list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, //nav menu toggle icon
R.string.app_name, // nav drawer open - description for accessibility
R.string.app_name // nav drawer close - description for accessibility
) {
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
// on first time display view for first nav item
displayView(0);
}
}
And finally, i just need to extend the BaseActivity class and code like usual.
UPDATE
According to the answer, this is my WORKING overrided setContentView :
@Override
public void setContentView(final int layoutResID) {
// TODO Auto-generated method stub
mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); // Your base layout here
actContent= (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);
getLayoutInflater().inflate(layoutResID, actContent, true);
super.setContentView(mDrawerLayout);
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.list_slidermenu);
navDrawerItems = new ArrayList<NavDrawerItem>();
// adding nav drawer items to array
// Home
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
// Find People
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
// Photos
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
// Communities, Will add a counter here
navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));
// Pages
navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
// What's hot, We will add a counter here
navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));
// Recycle the typed array
navMenuIcons.recycle();
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
// setting the nav drawer list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, //nav menu toggle icon
R.string.app_name, // nav drawer open - description for accessibility
R.string.app_name // nav drawer close - description for accessibility
) {
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
//super.setContentView(mDrawerLayout);
/*getLayoutInflater().inflate(layoutResID, actContent, true);
super.setContentView(mDrawerLayout);*/
}
回答1:
Change your setContentView() like this...
@Override
public void setContentView(int layoutResID) {
mDrawerLayout = (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null);
actContent = (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);
// set the drawer layout as main content view of Activity.
setContentView(mDrawerLayout);
// add layout of BaseActivities inside framelayout.i.e. frame_container
getLayoutInflater().inflate(layoutResID, actContent, true);
}

I know this is already answered, but in case someone struggles with my specific problem:
DrawerLayout can only have 2 childs, content and the navigationView.
if you want to include a toolbar you should wrap this inside another layout or outside the drawerlayout:
DrawerLayout
--LinearLayout (or any other layout)
----Toolbar
----Content
--NavigationView
or:
LinearLayout (or any other layout)
--Toolbar
--DrawerLayout
----Content
----NavigationView
