Fullscreen Dialog Fragment not showing correctly

Fullscreen Dialog Fragment not showing correctly - android

I've got two problems:
In my app I have an activity with the appbar and a recycler view.
When i click an option of the floating action menu it displays a Fullscreen Dialogfragment but for some reason the dialog is not showing correctly (not totaly fullscreen).
Here is the result
dialogfragment
Also when I click the close button of the Dialog it closes not only the dialog, but the activity as well, and goes to the previous activity.
What should I do. I am beginning Android.
also I want to establish a margin for the cardview (left and right)
Here is my code

First of all your dialog layout has top padding so that why it has no full height.
dialog_contract.xml
<android.support.design.widget.CoordinatorLayout
...
android:paddingTop="24dp"
>
Second of all try following java naming convention since your code is realy hard to read
Also when I click the close button of the Dialog it closes not only the dialog, but the activity as well, and goes to the previous activity.
My best guess is that you are not handling menu clicks correctly, try calling
setHasOptionsMenu(true);
from dialogFragmen onCreate

Problem with displaying top app and contextual action bar in fragment

Initially, I tried to make the context menu appear after a long press on the RecyclerView element of the first fragment.
Then I decided to make it at least appear.
My application consists of three chunks. I am using material design components. The top menu is displayed on the activity layout, and for now it should only change to the contextual menu of the first fragment.
Now the contextual menu is displayed by clicking on the RecyclerView element of the first fragment, but it appears, and the top menu does not disappear.
I need to display Toolbar Material separately on each fragment and somehow replace it with contextual one? Explain, please.

Ok, I fixed this by adding this <item name="windowActionModeOverlay">true</item> to the style. But the question remains the same - am I doing the right thing by displaying the top menu in the activity, and displaying the contextual action bar in the fragment?

can someone help or with better approach but i don't want to use activity i need fragment with action bar.

i solved my problem by removing

Converting ActivityGroup app to use Fragments/FragmentGroup

I have an app that I desperately need to convert from using the old ActivityGroup class to Fragments. I'm not sure how to go about it though. Below is a sample of the code I use now. Could anyone provide some insight into what steps I should take to start switching it over to use Fragments / FragmentManager instead?

public class StatusGroupActivity extends TabGroupActivity
{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
startChildActivity("Status", new Intent(this,Status.class));
}
}
... so basically when my app loads, I get my tabs at the bottom, my header at the top, and the "tab content" in the middle. In my Status activity, I can load another activity from it by using ...
Intent intent = new Intent(getParent(), SomeOtherActivity.class)
TabGroupActivity parentActivity = (TabGroupActivity)getParent();
parentActivity.startChildActivity("Some Other Activity", intent);
... and it loads the SomeOtherActivity activity into the content area. Hitting back takes me back to the Status screen.
Any pointers, examples and assistance with converting this over to use Fragments is so greatly appreciated. I will gladly donate 500 of my rep. points for a full example.

In my current TabGroupActivity class, in the finishFromChild and startChildActivity methods, I am able to call setText on the txtViewHeading TextView element in my main activity layout. Which is the current activities "title". If there is more than 1 activity in the group, the back button shows the previous title. How can I duplicate this in the examples below? The main activity layout there is much different than mine.

First you need to add Design Support Library and AppCompatLibrary into your Project
Add this code into your app gradle
compile 'com.android.support:appcompat-v7:24.0.0'
compile 'com.android.support:design:24.0.0'
layout for activity_main.xml (like main.xml in your code)
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="#dimen/appbar_padding_top"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
In above layout ViewPager will provides horizontal layout to display tabs. You can display more screens in a single screen using tabs. You can swipe the tabs quickly as you can.
Root Fragment
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/root_frame" >
View for First Fragment
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:background="#ff0"
android:layout_height="match_parent" >
<TextView
android:id="#+id/tv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:text="#string/first_fragment" />
<Button
android:id="#+id/btn"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:text="#string/to_second_fragment"/>
</RelativeLayout>
View for Second and Individual(s) Fragment.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin">
<TextView
android:id="#+id/section_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
Now add a MainActivity(like Main Activity in yours code) under which all this thing will handle.
public class MainActivity extends AppCompatActivity {
private TabGroupAdapter mTabGroupAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ArrayList<Fragment> fragmentList = new ArrayList<Fragment>();
fragmentList.add(new RootFragment());
fragmentList.add(new IndividualFragment1());
fragmentList.add(new IndividualFragment2());
ArrayList<String> name = new ArrayList<String>() {
{
add("Root Tab");
add("Second Tab");
add("Third Tab");
}
};
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mTabGroupAdapter = new TabGroupAdapter(getSupportFragmentManager(),name, fragmentList,);
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mTabGroupAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
}
}
There is one FragmentPagerAdapter defined as mTabGroupAdapter inside MainActivity that will add a different tabs inside a single Layout.
First we bind the mTabGroupAdapter to mViewPager.
TabLayout will act like a TabHost under which Tab will be added by FragmentPagerAdapter.
mViewPager is bind to the Tablayout.
Under MainActivity TabLayout will display the name of Tabs.
TabGroupAdapter
public class TabGroupAdapter extends FragmentPagerAdapter {
private ArrayList<Fragment> fragmentList = new ArrayList<Fragment>();
private ArrayList<String> fragment_name;
public TabGroupAdapter(FragmentManager fm, ArrayList<String> name, ArrayList<Fragment> list) {
super(fm);
this.fragmentList = list;
this.fragment_name = name;
}
#Override
public Fragment getItem(int position) {
return fragmentList.get(position);
}
#Override
public int getCount() {
return fragmentList.size();
}
#Override
public CharSequence getPageTitle(int position) {
return fragment_name.get(position);
}
}
In TabGroupAdapter you would pass a List of fragments(or single fragment) and list of fragments name(or single name) as arguments in the Constructor.
IndividualFragment(s) will act like a individual Tab instead of Activity.
RootFragment will be acting as a container for other fragments( First Fragment and Second Fragment)
Root Fragment
public class RootFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.root_fragment, container, false);
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.root_frame, new FirstFragment());
fragmentTransaction.commit();
return view;
}
}
First Fragment
public class FirstFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.first_fragment, container, false);
Button btn = (Button) view.findViewById(R.id.btn);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
//use the "root frame" defined in
//"root_fragment.xml" as the reference to replace fragment
fragmentTransaction.replace(R.id.root_frame, new SecondFragment());
/*
* allow to add the fragment
* to the stack and return to it later, by pressing back
*/
fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
}
}
Second Fragment
public class SecondFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
return rootView;
}
}
Individual(s) Fragment
public class IndividualFragment1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
return rootView;
}
}
public class IndividualFragment2 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
return rootView;
}
}
In OnCreateView method you would set a layout of a Tab .
You won't have to use the getTabHost() method.
Let me know if you persist any problem.
Whenever you want to dynamically change or update the Tabs in View Pager just add or remove item from fragmentList and call this method mTabGroupAdapter.notifyDataSetChanged(); inside MainActivity.

Add these dependencies to your project:
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
First change your Main activity must be extended from AppCompatActivity.
Than change your main activity's layout like below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/coordinatorlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".Main">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbarlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include
layout="#layout/toolbar_default"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:tabGravity="fill"
app:tabMaxWidth="0dp"
app:tabIndicatorHeight="4dp"
app:tabMode="fixed"
app:tabIndicatorColor="#android:color/white"
android:background="#color/AppPrimary"/>
</android.support.design.widget.AppBarLayout>
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".dashboard.DashboardActivity"
tools:showIn="#layout/activity_dashboard">
<android.support.v4.view.ViewPager
android:id="#+id/viewpager_main"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
And here's a toolbar layout example. You can customize however you want.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar_main"
style="#style/Widget.MyApp.Toolbar.Solid"
android:layout_width="match_parent"
android:layout_height="#dimen/abc_action_bar_default_height_material"
android:background="#color/AppPrimary"
app:contentInsetEnd="16dp"
app:contentInsetStart="16dp" />
Than you need to create fragments which you'll use in your tabs instead of activities which you use for tabs. In this case this'll your Status Activity if i'm not wrong.
Define a StatusFragment like below:
public class StatusFragment extends Fragment
{
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
// this is your Status fragment. You can do stuff which you did in Status activity
}
}
Than you need to define a tabs adapter which you'll bind with your tabs and convert your TabHost to Fragment/Fragment manager type. Titles string array contains strings which you'll show in your tabs indicator. Such as "Status, My Assume Tab, My awesome tab 2
public class DashboardTabsAdapter extends FragmentPagerAdapter {
private String[] mTitles;
public DashboardTabsAdapter(FragmentManager fm, String[] titles) {
super(fm);
this.mTitles = titles;
}
#Override
public Fragment getItem(int position) {
return new StatusFragment();
// You can define some other fragments if you want to do different types of operations in your tabs and switch this position and return that kind of fragment.
}
#Override
public int getCount() {
return mTitles.length;
}
#Override
public CharSequence getPageTitle(int position) {
return mTitles[position];
}
}
And finally in your Main activity find your view pager, tabs create a new adapter and bind them.
final TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
final DashboardTabsAdapter dashboardTabsAdapter = new DashboardTabsAdapter(getSupportFragmentManager(), getResources().getStringArray(R.array.tab_titles));
mViewPagerMain = (ViewPager) findViewById(R.id.viewpager_main);
mViewPagerMain.setOffscreenPageLimit(3);
mViewPagerMain.setAdapter(dashboardTabsAdapter);
tabLayout.setupWithViewPager(mViewPagerMain);
Edit: You'll no longer need TabHost and TabActivity any more. Your tab grup activity will be your ViewPager which handles screen changes and lifecycle of fragments inside. If you need to get this activity from fragments you can use getActivity() method and cast it to your activity and use it's public methods.

Navigation drawer implementation with activities using inheritance

In my app I have to use navigation drawer with all activities. So I have created a base activity called DrawerActivity. I wrote the code for navigation drawer in DrawerActivity and then extended the UserDashBoardActivity from DrawerActivity.
The problem is that DrawerActivity properties aren't executed in UserDashBoardActivity. I can't interact with DrawerActivity in UserDashBoardActivity. Here that drawer menu is in ActionBar in all the activities.
This is my DrawerActivity
public class DrawerActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_list_view);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerItems = getResources().getStringArray(R.array.navigation_drawer_items_array);
//mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(
this, R.layout.drawer_list_items, mDrawerItems));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout, R.drawable.ic_menu,
R.string.drawer_open, R.string.drawer_close) {
public void onDrawerOpened(View view) {
invalidateOptionsMenu();
}
public void onDrawerClosed(View view) {
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
for (int index = 0; index < menu.size(); index++) {
MenuItem menuItem = menu.getItem(index);
if (menuItem != null) {
// hide the menu items if the drawer is open
menuItem.setVisible(!drawerOpen);
}
}
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}

The UserDashboard activity is executed as it is but I need the property of DrawerActivity to be executed along with this activity. How to do it?

Let the parent Activity add the required ViewGroup as child of the FrameLayout. To achieve this, use the following method for DrawerActivity:
protected void addToContentView(int layoutResID)
{
// as part of onCreate() we had already
// setContentView(R.layout.activity_drawer);
if (layoutResID >= 0)
{
Toast.makeText(this, "activity content found", Toast.LENGTH_LONG).show();
FrameLayout fl = (FrameLayout)findViewById(R.id.activity_frame);
View.inflate(this, layoutResID, fl);
}
else
{
Toast.makeText(this, "activity content missing", Toast.LENGTH_LONG).show();
}
}
Then, in the onCreate() method of the child Activity:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// call this instead of setContentView()
addToContentView(R.layout.activity_user_dashboard);
// put here your code as before...
}

Drawer's layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
/>
<!--you need to add everything to this frameLayout then only you will be able to access Navigation DrawerLayout-->
<FrameLayout
android:id="#+id/fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"></FrameLayout>
</LinearLayout>
<ListView
android:id="#+id/navigation_list"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:fitsSystemWindows="true"
android:background="#color/white"
/>
</android.support.v4.widget.DrawerLayout>
The Activity with Drawer:(Only important code is shown)
public abstract class BaseDrawerLayoutActivity extends AppCompatActivity implements OnItemClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.base_drawer_layout_activity);
//rest of the things
//NOTE: loadNavMenu is abstract so that you can implement it in other activities as per you need, otherwise remove this and load it here itself
loadNavMenu();
}
protected abstract void loadNavMenu();
// call this method whenever you enter new activity and load the fragment here.
public void showFragment(Fragment object, String title) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment, object);
transaction.commit();
}}
Those activities which need the drawer menu can inherit above class. Not inflate all the layout's inside FrameLayout only.
public class MainActivity extends BaseDrawerLayoutActivity {
public static final String TAG = OLMSActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//the method below will call the BaseDrawerLayoutActivity method and change the fragment for you to see.
showFragment(new MyProfileFragment(), "My Profile");
}
#Override
protected void loadNavMenu() {
NavItems.clear();
//load your menu items
}
private void loadNavFavourites(){
//todo
}}
MyProfileFragment is just a class with fragment and this one call inflate a layout in its OnCreateView method.

The ViewPager doesn't scroll at al after refreshing the data

I have an activity which has a coordinator layout with viewpager and CircularPager Indicator. I am trying to use MaterialRefreshLayout Library to do pull to refresh
The library can be found at Pull to refresh library
However, after I use pull to refresh my data, the viewpager just doesn't update the rest of the fragment and hence it dosn't scroll. Once I do background foreground it scrolls alright. Below is the Layout and activity

And Below is the Activity
public class HomeActivity extends AppCompatActivity {
private SectionPagerAdapter mSectionPagerAdapter;

private CirclePageIndicator mPagerCountIndicator;

return super.onOptionsItemSelected(item);
}

}
}
};
for(int taskCount = 1; taskCount <= mTaskCount; taskCount ++){

}
}

};
for(int taskCount = 1; taskCount <= mTaskCount; taskCount ++){
myAsyncTask = new MyAsyncTask();
startMyAsyncTask(myAsyncTask );
}
}
private void updateViewPager(){
mSectionPagerAdapter.setPagerItem(myMap);
mSectionPagerAdapter.notifyDataSetChanged();
mCartCountIndicator.notifyDataSetChanged();
mViewPager.invalidate();
}
}
Not Sure what am I doing wrong here. Appreciate any suggestion.

use
mViewPager.setOffscreenPageLimit(numberOfPages);

Okay, figured since it is the activity that is not being refreshed itself I tried this.onResume() in the refresh method once I do notifyDataSetChanged(). It works.
Not sure it is the cleanest solution though
