I am trying to make a ListView with TextViews, I want each textview to be able to be clicked and based on it's position a Fragment is pulled up. However, the itemOnClickListener seems to not even be called.
mDrawerList = (ListView) findViewById(R.id.devices_drawer);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, drawerInfo));
mDrawerList.setItemsCanFocus(false);
mDrawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
final int pos, long id) {
Log.d(TAG, "CLICKED " + pos);
selectDevice(pos);
}
});
here's the xml for the list item:
<?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="vertical" >
<TextView
android:id="#+id/deviceText"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
List view xml file:
<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" >
<ListView
android:id="#+id/devices_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.DrawerLayout>
It's your whole xml drawer (I presume you try to do a navigation drawer) ? If you have a parent layout check the android:descendantFocusability="blocksDescendants" otherwise you have to wrap your textview in a layout (LinearLayout is sufficient if you don't have a complex UI for the item).
The new OnItemClickListener is an AdapterView.OnItemClickListerner?
(An excellent how-to http://www.vogella.com/articles/AndroidActionBar/article.html#actionbar_navigation_drawer )
Is there a reason you are using mDrawerList.setItemsCanFocus(false);? You don't have any focusable items in your item layout, so it's safe to remove that call. Should work ok after that.
Also check if you are using Button in list row item, it'll over-ride you list item click event
For list items inside your list.. you have to set the attributes below
android:focusable="false"
android:focusableInTouchMode="false"

I have a listview which occupies all the space of the layout IN THEORY, but actually it occupies only half of the layout because it has got only 5 elements and it doesn't cover all the screen. I'd like to know when I touch OUTSIDE of the listview. I tried to create a clicklistener method for the layout of the listfragment which contains the list, but it is never used because IN THEORY the listview occupies all the layout, so the click isn't found. It is the same for the layout of the activity more or less. In that case the click is found only on the edges, so I can't find a method to solve my problem.
Here is the fragment layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#android:id/list" />
Here is the activity layout:
<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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context="com.example.utente.actionbar.MainActivity">
<Button
android:text="MULTI"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="26dp"
android:id="#+id/button" />
<Button
android:text="SINGOLO"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/button"
android:layout_alignLeft="#+id/button"
android:layout_alignStart="#+id/button"
android:layout_marginBottom="25dp"
android:id="#+id/button2" />
IN THEORY the listview occupies all the layout
Not a theory, that is exactly what happens; by using android:layout_height="match_parent" the View will always take the full screen height.
listView.setOnClickListener would work if you want to see if you clicked anywhere in the ListView, but you typically would instead want listView.setOnItemClickListener to see if you have clicked on any single item, and not the entire list.
Refer: difference between onClickListener and onItemClickListener
If you really want to shrink the ListView, then android:layout_height="wrap_content" is an option, but I'm not sure that works without content actually being loaded into that View since the content wrapping is applied at inflation-time, which since it has no adapter set, can't be done.
If you are needing to detect a listener literally "outside the ListView", then you need to set some type of click / touch listener on the rootView of that Fragment.
public View onCreateView(...) {
rootView = inflater.inflate(...);
listView = ...;
listView.setOnTouchListner(...
#Override
public boolean onTouch(View v, MotionEvent event) {
return false; // Says that click was not handled here.
}
});
rootView.setOnTouchListner(...
// TODO: Check if click landed outside the ListView
#Override
public boolean onTouch(View v, MotionEvent event) {
if (v.getId() != android.R.id.listView) { // Not the list
if (event.getAction() == MotionEvent.ACTION_UP) {
// Up action more reliable than "down"
return true;
}
}
}
);
return rootView;
}
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content" <!-- Or specific height -->
android:id="#android:id/list" />
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/clickView" />
</LinearLayout>
In Fragmet
public View onCreateView(...) {
rootView = inflater.inflate(...);
View clickView = rootView.findViewById(...);
clickView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Do something here
}
});
return rootView;
}
I guess this solves your problem.
I am doing a time management app for android for my project in school. So there is a class called Activity which represents the activities done by the user through the day(Like going to school,listening to music,eating etc). Activity objects have an instant variable called done which is type of boolean and another insant variable Tags which is a Tag array. There is need for boolean done because user can enter activities for the future and later he/she can mark it as done. Tag class is for the user to label their activities(For example an activity can have tags: sport and hobby at the same time).These activities entered by the user to the program are shown in a fragment called Activities fragment. There will be 2 different Listviews in this fragment one for done and the other for undone activities. So I wrote my xml code so that it would have 2 Listviews on top of each other and added this listviews to my fragment. However, when I run my code I only can see one of the Listviews, the other one does not show up.This is how my xml file look like:(here is the picture of the design:http://postimg.org/image/a7u1ynfzb/)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/listView2"
/>
</LinearLayout>
Here is my code for fragment class:
public class ActivitiesFragment extends Fragment {
public ActivitiesFragment() {
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
ArrayList<Tag> tags1= new ArrayList<Tag>();
tags1.add(new Tag("Tag1"));
ArrayList<Tag> tags2= new ArrayList<Tag>();
tags2.add(new Tag("Tag2"));
com.beter.timehole.core.Activity doneSample = new com.beter.timehole.core.Activity("Work",true,70,"16 50","17 00",tags1,"did it");
com.beter.timehole.core.Activity undoneSample = new com.beter.timehole.core.Activity("Fun",false,30,"13 30","14 00",tags2,"will do it");
View rootView = inflater.inflate(R.layout.activity_fragment, container, false);
ArrayList<com.beter.timehole.core.Activity> doneActivities = new ArrayList<com.beter.timehole.core.Activity>();
doneActivities.add(doneSample);
ListView doneList = (ListView) rootView.findViewById(R.id.listView1);
doneList.setAdapter(new ArrayAdapter<com.beter.timehole.core.Activity>(getActivity(), R.layout.support_simple_spinner_dropdown_item, doneActivities));
ArrayList<com.beter.timehole.core.Activity> undoneActivities = new ArrayList<com.beter.timehole.core.Activity>();
undoneActivities.add(undoneSample);
ListView undoneList = (ListView) rootView.findViewById(R.id.listView2);
undoneList.setAdapter(new ArrayAdapter<com.beter.timehole.core.Activity>(getActivity(),R.layout.support_simple_spinner_dropdown_item,undoneActivities));
return rootView;
}
}
Try to Change layout_height="0dp" .
Try this layout code.
`
<!-- TODO: Update blank fragment layout -->

android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1" />

If this is not working try to check your code or put your complete code here.
Please try this

I have two xml files. One of them contains the ListView and the one who populates the listView. I was
able to display the items but the thing is, it can't be scrolled. For example, I have list of items to display but it will not automatically enables scroll. Which part of the code should be enhanced so that it will allow scrolling. I know that listView enables scrolling by default. Please help me with this one. Thanks in advance.

I think it would work better if you used the constraints of a RelativeLayout to contain your ListView.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<!-- Main ListView
Always give id value as list(#android:id/list)
-->
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content" >
</ListView>
</RelativeLayout>
The visual top of your ListView will be at the top of the parent view, the visual bottom will be at the bottom of the parent view, and your content will be as long as your list happens to be, and scroll where it needs to.
Hey, I want to change the TypeFace of one of the TextViews to an external font.. How can I do that?
Code:
public class English extends Activity {
<...>
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.quran_english);
listview=(ListView) findViewById(R.id.QuranEnglishListView);
<..add into list..>
SimpleAdapter adapter = new SimpleAdapter(
this,
list,
R.layout.quran_english_row,
new String[] {"Arabic","English"},
new int[] {R.id.QuranEnglishTextViewArabic,R.id.QuranEnglishTextViewEnglish});
listview.setAdapter(adapter);
xml for each row (quran_english_row.xml):
<?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">
<LinearLayout android:gravity="right" android:layout_height="wrap_content" android:id="#+id/linearLayout1" android:layout_width="fill_parent">
<TextView android:textSize="21px" android:text="TextView" android:id="#+id/QuranEnglishTextViewArabic" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
</LinearLayout>
<TextView android:textSize="21px" android:text="TextView" android:id="#+id/QuranEnglishTextViewEnglish" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
</LinearLayout>
xml for the layout (quran_english.xml):
<?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">
<ListView android:id="#+id/QuranEnglishListView" android:layout_width="fill_parent" android:layout_height="fill_parent"></ListView>
</LinearLayout>
This crashes because of NullPointer:
((TextView) findViewById(R.id.QuranEnglishTextViewArabic)).setTypeface(Typeface.createFromAsset(getAssets(),"dejavusans.ttf"));
So how can I reach the TextView that is in the row to change its TypeFace? Thanks
You can try to get the layout for each list item by
View rowView = adapter.getView(...);
Then get the TextView of the layout by
TextView txt = (TextView)rowView .findViewById(R.id.QuranEnglishTextViewEnglish);
txt.setTypeFace(...);
and set your TypeFaces. Haven't tested that yet, but i guess it could work.
But I recommend extending your own BaseAdapter. Then create another list-row class which provides the inflated layouts for your BaseAdapter. There you'll be able to set the typefaces easily for every TextView.
try this links it works http://techdroid.kbeanie.com/2011/04/using-custom-fonts-on-android.html see steps and class MyTextView and MyButton shown above layout
I have a ListView that uses SimpleAdapter, each row has 2 TextViews, and I would like to use an external font to one of the two TextView.. Here is the code of the class:
public class QuranEnglish extends Activity {
<...>
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.quran_english);
listview=(ListView) findViewById(R.id.QuranEnglishListView);
<..add into list..>
SimpleAdapter adapter = new SimpleAdapter(
this,
list,
R.layout.quran_english_row,
new String[] {"Arabic","English"},
new int[] {R.id.QuranEnglishTextViewArabic,R.id.QuranEnglishTextViewEnglish});
listview.setAdapter(adapter);
xml for each row (quran_english_row.xml):
<?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">
<LinearLayout android:gravity="right" android:layout_height="wrap_content" android:id="#+id/linearLayout1" android:layout_width="fill_parent">
<TextView android:textSize="21px" android:text="TextView" android:id="#+id/QuranEnglishTextViewArabic" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
</LinearLayout>
<TextView android:textSize="21px" android:text="TextView" android:id="#+id/QuranEnglishTextViewEnglish" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
</LinearLayout>
xml for the layout (quran_english.xml):
<?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">
<ListView android:id="#+id/QuranEnglishListView" android:layout_width="fill_parent" android:layout_height="fill_parent"></ListView>
</LinearLayout>
So how can I put the external typeface of the TextView that is in the row (quran_english_row.xml)? I tried using this line though it crashed my application:
((TextView) findViewById(R.id.QuranEnglishTextViewArabic)).setTypeface(Typeface.createFromAsset(getAssets(),"dejavusans.ttf"));
R.id.QuranEnglishTextViewArabic
is not an id of one of your views here. It is an id of a example view, which is used to fill the list. In order to change the font, you need to get one view of your list. This works if you have chosen one of your views:
TextView view = getSelectedView();
if (view != null) {
view.setTypeface(Typeface.createFromAsset(getAssets(),"dejavusans.ttf"));
}
