I'm following this link and using this exact same code to make this flowing drawer but i'm using eclipse and for the life of me i can't figure out the problem.
Iam using exact this code so i don't know what to post here.
I'll just post my main activity here. In logcat its crashing on setcontentview. I'll also post my .xml file
public class MainActivity extends AppCompatActivity {
private RecyclerView rvFeed;
private LeftDrawerLayout mLeftDrawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
System.out.println("Calling Layout");
setContentView(R.layout.activity_main);
System.out.println("Layout Called");
setupToolbar();
mLeftDrawerLayout = (LeftDrawerLayout) findViewById(R.id.id_drawerlayout);
rvFeed = (RecyclerView) findViewById(R.id.rvFeed);
FragmentManager fm = getSupportFragmentManager();
MyMenuFragment mMenuFragment = (MyMenuFragment) fm.findFragmentById(R.id.id_container_menu);
FlowingView mFlowingView = (FlowingView) findViewById(R.id.sv);
if (mMenuFragment == null) {
fm.beginTransaction().add(R.id.id_container_menu, mMenuFragment = new MyMenuFragment()).commit();
}
mLeftDrawerLayout.setFluidView(mFlowingView);
mLeftDrawerLayout.setMenuFragment(mMenuFragment);
setupFeed();
}
protected void setupToolbar() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.ic_menu_white);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mLeftDrawerLayout.toggle();
}
});
}
private void setupFeed() {
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this) {
#Override
protected int getExtraLayoutSpace(RecyclerView.State state) {
return 300;
}
};
rvFeed.setLayoutManager(linearLayoutManager);
FeedAdapter feedAdapter = new FeedAdapter(this);
rvFeed.setAdapter(feedAdapter);
feedAdapter.updateItems();
}
#Override
public void onBackPressed() {
if (mLeftDrawerLayout.isShownMenu()) {
mLeftDrawerLayout.closeDrawer();
} else {
super.onBackPressed();
}

Try the following.
Clean your project,
Rebuild your project,
Get Build on Gradle.
If you'll not get it run, check your build.gradle file whether you have added that library in dependencies.

I have gone through similar questions and their solutions here, but I can't get past my issue after spending few hours on it. I looked at many solutions, tried them, but still can't get to see the navigation drawer on my screen. I will really appreciate if someone could tell me what am I missing here.
Thanks in advance.
Here's my xml :

I don't see any output.Screen output
seems that there should be problem in your layout file.
Remember that DrawerLayout allows maximum 2 child views. Have
a look at this Google Doc.

You need to toggle the open/close of the drawer.
To do so, you can do the following :
1 - Implement the toggleDrawer method
public void toggleDrawer(boolean shouldBeVisible){
if(shouldBeVisible){
dlayout.openDrawer(dlayout);
} else {
dlayout.closeDrawers();
}
}
2 - Call it on onCreate (note : this is just for testing)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
toggleDrawer(View.VISIBLE);
}
3 - Like Daryl said, implement a button so you can actively toggle (open and close the drawer to your liking)
myButton = (Button) findViewById(R.id.myButton);
myButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v){
if(dlayout.getVisiblity() == View.VISIBLE) {
// drawer is visible -> close
toggleDrawer(false);
} else {
// drawer is gone/invisible -> open
toggleDrawer(true);
}
}
})
4 - (Make sure your DrawerLayout contains only 2 child views)
To add a navigation drawer, declare your user interface with a
DrawerLayout object as the root view of your layout. Inside the
DrawerLayout, add one view that contains the main content for the
screen (your primary layout when the drawer is hidden) and another
view that contains the contents of the navigation drawer.
Note : Forgot to add this but is indeed an invaluable reference (thanks to #Meet, upvoted)
Please, anybody help me. I have a 2 big problem:
App bar moves my left button to center app, right after string:
setSupportActionBar(mToolbar)
buttons - wrap/wrap, tryed to wrap her in RelativeLayout, tryed to set "anchor" parameter - no effect - title moves her then appears.
Fragments appears higher then fragmentContainer - on my appbar.
My idea was - 1 main activity + 3 fragments changes in her bottom part, and settings-activity. Screen applied.
Also I have a question:
For now I changes fragment using .replace - method. If I do it then I send search query and receive list of elements - it would create a new main fragment with empty list? But now it's not important. Of course, I can get fragments by tag, if one exists.
Code.

I'm trying to add pull to refresh functionality into listview.
In fragment_page.xml (here is defined global listview)
<LinearLayout
style="#style/AppTheme.BaseActivity"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
tools:context="xx.view.fragment.PageFragment">
<TextView
android:id="#android:id/empty"
style="#style/AppTheme.WrapContent.NoResult"
android:text="#string/no_results"/>
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swiperefresh"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:listSelector="#drawable/list_selector"/>
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>
And in Activity:
public class MessageActivity extends TabBaseActivity implements ManageView, OnRefreshListener {
private MessageController mMessageController;
private int mSelectedTab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
init();
setUp(new String[]{"Unread", "Read", "Sent", "All"}, Constants.Adapter.MESSAGE_ADAPTER);
mMessageController.loadMessages();
//START Swipe to refresh
try {
final SwipeRefreshLayout swipeContainer = (SwipeRefreshLayout) findViewById(R.id.swiperefresh);
if(swipeContainer == null) {
Logger.d("Null");
}
swipeContainer.setEnabled(false);
swipeContainer.setOnRefreshListener(this);
} catch (Exception e) {
Logger.e(e.getMessage());
}
//END Swipe to refresh
}
But swipeContainer is still null.
I tried to to it using the following tutorials:
http://www.androidhive.info/2015/05/android-swipe-down-to-refresh-listview-tutorial/
and
http://www.survivingwithandroid.com/2014/05/android-swiperefreshlayout-tutorial.html
But without the luck.
How can i solve it please?
Many thanks for any advice.
EDIT:
Content for view is set in init:
private void init() {
mMessageController = MessageController.getInstance(this, getSupportFragmentManager());
mMessageController.setView(this);
mSelectedTab = 0;
}
If you want to use your views in fragment (SwipeRefreshLayout, etc.), initialize your views in onActivityCreated() method. Once onActivityCreated() was called, you knew the activity was ready to be called upon.
Is it possible to keep the actionbar visible using the mikepenz's material drawer library?
Yes this is possible. Just see the sample application. This contains the CustomContainerActivity which showcases how you can have a Drawer which is below the Toolbar
public class CustomContainerActivity extends AppCompatActivity {
//save our header or result
private Drawer result = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample_custom_container_dark_toolbar);
// Handle Toolbar
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle(R.string.drawer_item_custom_container_drawer);
//Create the drawer
result = new DrawerBuilder(this)
//this layout have to contain child layouts
.withRootView(R.id.drawer_container)
.withToolbar(toolbar)
.withActionBarDrawerToggleAnimated(true)
.addDrawerItems(
new PrimaryDrawerItem().withName(R.string.drawer_item_home).withIcon(FontAwesome.Icon.faw_home),
new PrimaryDrawerItem().withName(R.string.drawer_item_free_play).withIcon(FontAwesome.Icon.faw_gamepad),
new PrimaryDrawerItem().withName(R.string.drawer_item_custom).withIcon(FontAwesome.Icon.faw_eye),
new SectionDrawerItem().withName(R.string.drawer_item_section_header),
new SecondaryDrawerItem().withName(R.string.drawer_item_settings).withIcon(FontAwesome.Icon.faw_cog),
new SecondaryDrawerItem().withName(R.string.drawer_item_help).withIcon(FontAwesome.Icon.faw_question).withEnabled(false),
new SecondaryDrawerItem().withName(R.string.drawer_item_open_source).withIcon(FontAwesome.Icon.faw_github),
new SecondaryDrawerItem().withName(R.string.drawer_item_contact).withIcon(FontAwesome.Icon.faw_bullhorn)
)
.withSavedInstance(savedInstanceState)
.build();
}
#Override
protected void onSaveInstanceState(Bundle outState) {
//add the values which need to be saved from the drawer to the bundle
outState = result.saveInstanceState(outState);
super.onSaveInstanceState(outState);
}
#Override
public void onBackPressed() {
//handle the back press :D close the drawer first and if the drawer is closed close the activity
if (result != null && result.isDrawerOpen()) {
result.closeDrawer();
} else {
super.onBackPressed();
}
}
}
Also note the different xml layout which is used in this Activity.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:elevation="4dp" />
<!-- the layout which will contain (host) the drawerLayout -->
<FrameLayout
android:layout_below="#id/toolbar"
android:id="#+id/drawer_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- the layout which will be the content of the activity (which will be hosted inside the drawer (NOT the list of the drawer)) -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/txtLabel"
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test"
android:textSize="16sp" />
</FrameLayout>
</FrameLayout>
</RelativeLayout>
This will produce the following:
I'm trying to adapt the strategy for hiding / showing a toolbar (or any visual element) from the well explained and great article:
http://mzgreen.github.io/2015/02/15/How-to-hideshow-Toolbar-when-list-is-scroling%28part1%29/
But in my case I'm using a Fragment to hold the recycleview instead of the activity. My problem is that the padding is not being applied so the first element is under the toolbar, and I have also another strange behavior, as the toolbar is also under the statusbar. I don't know what is happening here.
The following are my "moving pieces":
BasicActivity.java: based on the one given on the previous post, but moving away the recycleview part as is going to be on the Fragment piece. Also it exposes the show and hide methods to allow the fragment to access it:
public class BasicActivity extends ActionBarActivity {
private Toolbar mToolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_basic);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container,new RecycleFragment())
.commit();
overridePendingTransition(0, 0);
initToolbar();
}
private void initToolbar() {
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
setTitle(getString(R.string.app_name));
mToolbar.setTitleTextColor(getResources().getColor(android.R.color.white));
}
public void hideViews() {
mToolbar.animate().translationY(-mToolbar.getHeight()).setInterpolator(new AccelerateInterpolator(2));
}
public void showViews() {
mToolbar.animate().translationY(0).setInterpolator(new DecelerateInterpolator(2));
}
}
My activiy_basic.xml is the following:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<include layout="#layout/toolbar_actionbar" />
</FrameLayout>
The layout toolbar_actionbar.xml
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:clipToPadding="false"/>
The Fragment RecycleFragment.java:
public class RecycleFragment extends Fragment {
#Override public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_recycler, container, false);
return view;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
initRecyclerView(view);
}
private void initRecyclerView(View view) {
RecyclerView recyclerView = (RecyclerView)view.findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
RecyclerAdapter recyclerAdapter = new RecyclerAdapter(createItemList());
recyclerView.setAdapter(recyclerAdapter);
recyclerView.setOnScrollListener(new HidingScrollListener() {
#Override
public void onHide() {
((BasicActivity)getActivity()).hideViews();
}
#Override
public void onShow() {
((BasicActivity)getActivity()).showViews();
}
});
}
private List<String> createItemList() {
List<String> itemList = new ArrayList<>();
for(int i=0;i<20;i++) {
itemList.add("Item "+i);
}
return itemList;
}
}
And the layout for the fragment is just a recyclerview fragment_recycler.xml:
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
The adapter and the viewholder for the recycler are the same as the article, and they doesn't affect the behavior.
What is wrong with the code?
UPDATE:
A Michał Z. below pointed out. What was missing is the paddingTop and clipptoPadding on the Recyclerview view
So the final xml should be:
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="?attr/actionBarSize"
android:clipToPadding="false"/>
And to solve the statusbar overlapping problem, it is needed to add a "fitsystemwindows" = "true" element on the activity layout. So it must be as the following:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<FrameLayout android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<include layout="#layout/toolbar_actionbar" />
</FrameLayout>
UPDATE2
The fitSystemWindows is only needed if the theme is setting the statusbar as translucent
Your fragment_recycler.xml file is missing paddingTop and clipToPadding attributes.
It should look like this:
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="?attr/actionBarSize"
android:clipToPadding="false"/>
And also remove clipToPadding from your toolbar_actionbar.xml.
