Hello I have an surfaceview in my app.All my games are built like this:
Instanciating a subclass of Surfaceview which implements the SurfaceHolder.Callback interface.
Now is that I want to open a menu when I click on a Button(custom made object)
This should bring up a fragment with a scrollable textview( I thought of just a listview with one textview element inside it because I think the textview alone is not scrollable if the text is very long..any contrary arguments are welcome)
but how do I do this?
I have allready a Fragment class and a layout for the fragment
Edit 3:
Ok I've managed to set the SurfaceView programmatically like this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(savedInstanceState==null)
{
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
prefs=getSharedPreferences("myPrefs",0);
mView=new MainView(this);
loadSharedPrefs();
LinearLayout myLayout = (LinearLayout)findViewById(R.id.main);
mView.setLayoutParams(new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT));
myLayout.addView(mView);
}
}
where the layout is just a blank linearlayout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:id="#+id/main">
</LinearLayout>
So for now I just need a Fragment to be displayed when I click a Button
Here the Fragment Class so far:
public class HintListFragment extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.hintlist, container, false);
}
}
and the layout for this fragment:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/hintList"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="sagdjsahgdhascxasbcxahsgdhsagdhasgdashgdsajsgdh"
/>
</LinearLayout>
In your layout, wrap the surfaceview and a fragment in a FrameLayout. Make sure the fragment is on top of the surfaceview and then set the fragment's visibility to GONE. When you want to show the fragment, just set the visibility to VISIBLE
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<SurfaceView
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<com.example.MyFragment
android:visibility="gone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/myfragment"/>
</FrameLayout>

I noticed that onCreateView() of one of my fragments is never called and i dont know why.I need to be able to make changes in onResume() but thats is also never called.
Here is how I add the fragments.
public class LiveGameStats extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_live_game_stats);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.tab1, new Tab1Fragment()).commit();
}
FragmentTabHost mTabHost = (FragmentTabHost) findViewById(R.id.liveGameTabhost);
mTabHost.setup(LiveGameStats.this, getSupportFragmentManager(), R.id.liverealtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("You"),
LiveGameTab1Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Your Team"),
LiveGameTab2Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Your Enemies"),
LiveGameTab3Fragment.class, null);
}
Tab1Fragment
public class Tab1Fragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View V = inflater.inflate(R.layout.tab1, container, false);
Log.v("FRAGMENT","FragmentActivityCreateView");
return V;
}
And finnaly the xml passed under R.layout.tab1
<?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"
android:orientation="vertical"
tools:context=".DeviceFragment" >
<ImageButton
android:id="#+id/searchBtn"
android:src="#drawable/waves"
android:background="#drawable/search_selector"
android:padding="40dp"
android:layout_height="200dp"
android:layout_width="200dp"
android:onClick="liveMatch"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
I think I might have created the fragments the wrong way. As you see it now they are created as the xml says but when I changed tabs, the content is "reseted".Any changed I placed in onCreateView() or onResume() is not called.
EDIT
I have tried to implement the method described in the 1st comment. After the implementation the tabs have the same content. Is like all the tabs have the same content. This time I posted all my classes and their associated XML.
public class LiveGameStats extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_live_game_stats);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab1Fragment()).commit();
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab2Fragment()).commit();
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab3Fragment()).commit();
}
FragmentTabHost mTabHost = (FragmentTabHost) findViewById(R.id.liveGameTabhost);
mTabHost.setup(LiveGameStats.this, getSupportFragmentManager(), R.id.liverealtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("You"),
LiveGameTab1Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Your Team"),
LiveGameTab2Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Your Enemies"),
LiveGameTab3Fragment.class, null);
}
activity_live_game_stats.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I wont post the code from LiveGameTab2 and LiveGameTab3 since they are almost the same. I have also another activity that
Edit2
Seems its solved when i changed from getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab1Fragment()).commit(); to getSupportFragmentManager().beginTransaction().add(android.R.id.tabcontent, new LiveGameTab1Fragment()).commit();
The problem is this:
getSupportFragmentManager().beginTransaction().add(R.id.tab1, new Tab1Fragment()).commit();
In the first argument you have to pass a id to a container in the Activity layout where your fragment will be attached.
You are passing a entire layout R.id.tab1.
Add a container view in activity_live_game_stats xml file,
<?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"
android:orientation="vertical"
tools:context=".DeviceFragment" >
<FrameLayout
android:id="#+id/myContainer"
...(Other attrs)>
</FrameLayout>
</RelativeLayout>
and then
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.myContainer, new Tab1Fragment()).commit();
}
im trying to use setContentView to switch to a layout with a fragment inside it
but it crashes every time
what should i do?
this is my entire code:
(it must switch to fragment_layout when i click the button in the activity_main)
(fragmant_layout has a fragment and the layout for the frgment is te layout1)
(it crashs when i cick the button to switch)
main activity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void switchlayout(View view) {//when the button in clicked
setContentView(R.layout.fragment_layout);
}
}
the fragment class:
public class frgment extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.layout1,container,false);
}
}
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".fragmenttest.MainActivity">
<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="switchlayout"
android:layout_marginTop="74dp"
android:id="#+id/button" />
</RelativeLayout>
fragment_layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:name="alirezamellat.fragmenttest.frgment"
></fragment>
</LinearLayout>
layout1.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorAccent"></View>
</LinearLayout>
Please consider the following points::
On your parent layout (activity_main.xml), inside the Relative layout, add another layout called FrameLayout.
On your fragment layout(fragment_layout.xml), remove the fragment and add the layouts of layout1.xml to fragment_layout.xml
On your fragment class (MyFragment), inflate the fragment_layout.xml to the container and return the view (class name should start with uppercase letter, so name it like MyFragment)
On Activity class, place the following code on onclick listener.
//onClick on OnClickListener
MyFragment fragment = new MyFragment();
getSupportFragmentManager().beginTransaction()
.add(R.id.frame_layout, fragment)
.commit();
Once the layout of an Activity has been set it can not be changed at a later time.
There are a number of ways you can achieve this from which the easiest would be to have a wrapper layout and then injecting the fragment inside it using the FragmentManager class.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".fragmenttest.MainActivity">
<FrameLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="switchlayout"
android:layout_marginTop="74dp"
android:id="#+id/button" />
</RelativeLayout>
And then on your button click add your fragment.
getSupportFragmentManager().beginTransaction().add(R.id.wrapper, MyFragment.newInstance(), "FragTag").commit();
Remember that you have to take care of your button since it will still be visible on top of you fragment.
Hello im new android developer and i try to do the next things with no success
i have Activity, inside the activity i have fragment and inside it i have ** view pager image galley**.
the problem is when i run the app with the activity with the fragment and and gallery inside it the app crash
but when i tried to run the activity with the gallery and the fragment separately they works fine
whats the problem?
here my code:
Activity
public class infoActivity extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.hotel_info);
}
}
Activity XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<fragment
android:layout_width="match_parent"
android:layout_height="200dp"
android:name="co.checkit.mobile.checkit.Model.gallery_fragment"
tools:layout="#layout/imagegalleryfragment"
android:id="#+id/fragmentid" />
</LinearLayout>
ass you can see i set the fragment inside the activity
Fragment class
public class Hotelsgallery_fragment extends Fragment {
ImageAdapter adapter;
ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View myFragmentView = inflater.inflate(R.layout.imagegalleryfragment, container, false);
viewPager = (ViewPager)myFragmentView.findViewById(R.id.viewpager);
adapter = new ImageAdapter(this);
viewPager.setAdapter(adapter);
return myFragmentView;
}
}
i set the gallery inside the fragment class
Fragment XML
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/viewpager">
</android.support.v4.view.ViewPager>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/textView4"
android:layout_gravity="center_horizontal" />
</LinearLayout>
instead of putting fragment inside xml, put frame layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/frame_layout_id" />
</LinearLayout>
create fragment inside a activity, inflate using frame layout id
YourFragment fragment = new YourFragment();
FragmentTransaction ft = getSupportFragmentManager()
.beginTransaction();
ft.add(R.id.frame_layout_id, fragment);
ft.commit();
I'm trying to inflate a layout in another layout but it doesn't work...
In my activity I show activity_serie.xml which is black, and then I try to inflate on image_item.xml which is white. But I never see image_item.xml.
public class Serie extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_serie);
ViewPager mainLayout = (ViewPager) findViewById(R.id.serie_pager);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View menuLayout = inflater.inflate(R.layout.image_item, mainLayout, true);
}
#Override
protected void onResume() {
super.onResume();
}}
The activity_serie.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="#+id/serie_pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
The image_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:background="#FFFFFF"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</RelativeLayout>
Can someone tell me why?
Thanks.
findViewById(R.layout.activity_serie)
You should specify a view id here, not a layout name.
Why you wanna do that? Just put both views into one xml, and set android:visibility="gone" for one element. Than you can address layout by id and change visibility as much as you want.
I am stuck, I dont get how to implement a ListView that is inside a Fragment, I am trying to make a chat gui.
Is it possible to do something like this or am I totaly out in the wind?
Thanks for help! Regards a newbie! ^^
Here is the Fragment code:
public static class ChatFragment extends Fragment {
public ChatFragment() {
// Empty constructor required for fragment subclasses
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_chat, container, false);
/*FragmentManager fm = getActivity().getFragmentManager();
DataListFragment list = new DataListFragment();
fm.beginTransaction().add(R.id.list_message_History, list).commit();
*/
getActivity().setTitle(R.string.chat);
return rootView;
}
}
But as u see I dont udnerstand how to connect it all. I have med a customized ListFragment that uses a ArrayAdapter to handle the data.
Here is my layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#id/android:list"
android:orientation="horizontal">
<ListView android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"/>
</LinearLayout>
<LinearLayout 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:orientation="horizontal">
<EditText android:id="#+id/edit_message"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/edit_message" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_send" />
</LinearLayout>
</LinearLayout>
You don't have to add another Fragment inside your ChatFragment to just have a ListView. Get a reference for the ListView out of your layout like this:
ListView list = (ListView)rootView.findViewById(R.id.list);
Now set the adapter and the Array/List to it and you're done.
And don't make a Fragment transaction inside a Fragment. Use your Activity and the DrawerLayout for this job.
No need of ChatFragment
Make you activity a FragmentActivity and directly inflate the layout(R.layout.fragment_chat) with the ListFragment in that Activity.
class MainActivity extends FragmentActivity {
onCreate(Bundle extra) {
...
setContentView(R.layout.fragment_chat);
...
}
}
Check this example for using ListFragments.
