Android - Listview not showing the last item

Android - Listview not showing the last item - android

My Problem is the last item in the listview is not displaying even though it has been added to the adapter and as well as in the list as i can see the number of items in the adapter is ok. Is it the problem with the layout? this is my layout
<?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"

Thanks in advance.

Add this line to your Viewpager
android:layout_marginBottom="?attr/actionBarSize"
because the size you don't have at the bottom is exactly the size taken by your Toolbar
Example with RecyclerView
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view_trips"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:layout_marginBottom="?attr/actionBarSize"/>
Example with Viewpager
<android.support.v4.view.ViewPager
android:id="#+id/viewpager_trip_history"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="?attr/actionBarSize" />

Try this you can solve your problem with this:
You just need to change your xml file as below:
<?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:background="#drawable/golive_bg"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="6" >
<EditText
android:id="#+id/Room"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:layout_weight="4">
<requestFocus android:layout_width="wrap_content" />
</EditText>
<Button
android:id="#+id/Search1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Search"
android:layout_weight="1" />
<ImageButton
android:id="#+id/CreateRoomimageButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/closed_doorplus"
android:layout_weight="1" />
</LinearLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#+id/listRooms"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fastScrollEnabled="true"
android:transcriptMode="alwaysScroll">
</ListView>
</RelativeLayout>
</LinearLayout>

You can get the last item inside getView of the Adapter and change it layout params height by setLayoutParams. But the minus is you have to correct other items height because the height will change when scroll the list up/down

Maybe its very simple. Try to set the layout_height of your listview in the xml file to wrap_content.
android:layout_height="wrap_content"

Try to set the second LinearLayout holding the Listview to match_parent height... It seems like your LinearLayout is growing with the ListView (wrap_content) out of your screen space

When I press the button to delete an item from ListView it deletes the last one

I have next problem with a list view: So on the layout (prod_row) I set an image view(rvCls) that I want to delete an item while clicked. It deletes an item, but is always the last one. If I close this activity and I reopen it, it deletes the correct item, but what should I do to see the change instantly and not have to refresh the page?

There are 2 ways you could fix your code:
1.) Set position value as tag to your rvCls and fetch this tag for usage of position in your ClickListener
rvCls.setTag(position);
rvCls.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
produse.remove((int)v.getTag());
notifyDataSetChanged();
}
});
2.) Use a variable finalPosition in getView and use that as position inside ClickListener.
final int finalPosition = position;
rvCls.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
produse.remove(finalPosition);
notifyDataSetChanged();
}
});

I am new in android and this is my first post. I'm working with ListView. Apparently I am doing something quite wrong, but I cant figure out what is it.
This is the screenshot of the app, after it is gets completely installed:

In adapter constructor, some class variables's names are same with parameters's name. So, all manipulation will just be done for parameters, it makes size of this.titleArray will be zero then getCount() method always return 0 then no item appear on your activity. So you must use this to reference to the class variables. Modify your code as following:
public adapter(Context context, String[] titleArray, String[] descriptionArray) {
mContext = context;
this.titleArray = titleArray;
this.descriptionArray = descriptionArray;
layoutInflater = LayoutInflater.from(context);
}

How to remove selected item from all the other spinners in android

I am a beginner in android.I have a ListView containing a spinner,edittext and an imagebutton which is for deleting that row.The spinner is populated from a list.There is a add button which add these item to the listview when each time it clicks.If i select an item in a spinner then i need to remove that item from all the other spinner in that listview and also the items become visible when i deleted the selected spinner row or change the selected item in the spinner.Say for simplicity that my Spinners are populated with the following data:
{"data1", "data2", "data3", "data4", "data5"};
For example, if I select my first ListView's Spinner value to be "data3" and then the "data3" entry disappears from all the other ListView Spinner and this will appears back only when i change the selected value in the first listview spinner or deleting that row, similarly for each ListView spinner.How to do this? Somebody please help me.Below is my code.

Unable to see Search Box (EditText) when using ListView in Android

I'm trying to implement Custom ListView (i.e. ListView with custom Adapter) with Search Box, for that I have written the following XML code--

<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="20dp"

In design mode, when I clicks on Graphical Layout It is showing me proper/expected view (i.e. Search box to the Top and ListView Below to the search Box) but when I run my application then it is showing only ListView and SearchBox (EditText) is invisible. Please Help.

Change listview layout height to android:layout_height="0dp" instead of 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="match_parent"
android:orientation="vertical"
tools:context=".CustomListViewAndroidExample" >
<EditText
android:id="#+id/txtInputSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Search item.."
android:inputType="textVisiblePassword" />
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_marginTop="20dp"
android:layout_weight="1" />
</LinearLayout>
Edit Use RelativeLayout instead of LinearLayout as
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<EditText
android:id="#+id/txtInputSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:completionThreshold="1"
android:singleLine="true"/>
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000"
android:layout_weight="1"
android:layout_below="#+id/txtInputSearch"
android:drawSelectorOnTop="false"/>
</RelativeLayout>
Edit
Use EditText in your code instead of TextView ,So change
TextView txtInputSearch;
to
EditText txtInputSearch;
And
txtInputSearch=(TextView)findViewById(R.id.txtInputSearch);
to
txtInputSearch=(EditText )findViewById(R.id.txtInputSearch);

The problem is that you are adding a weight into you ListView which would take all the space of your layout, instead dont put any weight on it just simply wrap its height and remove the android:layout_weight="1"
sample:
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".CustomListViewAndroidExample" >
<EditText
android:id="#+id/txtInputSearch"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Search item.."
android:inputType="textVisiblePassword" />
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp" />
</LinearLayout>
problem:
txtInputSearch=(TextView)findViewById(R.id.txtInputSearch);
You are casting it to a TextView not an EditText.
change it to this:
EditText txtInputSearch;
txtInputSearch=(EditText)findViewById(R.id.txtInputSearch);

Update use code as per below
// On item click listener
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long itemId) {
RadioButton btn=(RadioButton) view.findViewById(R.id.startfromrb);
String sfrom = btn.getText().toString();
arrayAdapter.setSelected((int)itemId);
Log.i("STARTFROM", sfrom);
}
});
//Add below function in adapter class
public void setSelected(int selectedPosition){
this.selectedPosition=selectedPosition;
notifyDataSetChanged();
}
Also remove from adapter
rbStartFrom.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
selectedPosition = (Integer) v.getTag();
notifyDataSetInvalidated();
Log.i("IN ADAPTER", "" + selectedPosition);
}
});
And add android:clickable="false" and set selectedPosition to -1 by default

The first I see is, that You have to change the reference to the Views where You want to set the other views below :
<Spinner
android:id="#+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/lstDemo"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="#+id/spinner1" <!-- correct: #id/spinner1 -->
android:layout_marginBottom="60dp" >
</ListView>
<TextView
android:id="#+id/emptytv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/spinner1" <!-- correct: #id/spinner1 -->
android:layout_marginBottom="60dp"
android:gravity="center_vertical|center_horizontal"
android:text="No Records Found."
android:textSize="25sp" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginLeft="31dp"
android:text="Button" />
</RelativeLayout>
But anyway, Your TextView is sitten directly above the listView, is this Your intention? If not, You have to set
android:layout_below="#+id/lstDemo"
Also, if You get any errors, please post the logcat output. If You just have problems with Your layout, please explain clear enough what exactly You want.
EDIT
try to get the selected item String like this:
final String item = (String) parent.getItemAtPosition(position);
loadListView(item);

Develop Reference

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

Android - Listview not showing the last item - android

You can get the last item inside getView of the Adapter and change it layout params height by setLayoutParams. But the minus is you have to correct other items height because the height will change when scroll the list up/down

Maybe its very simple. Try to set the layout_height of your listview in the xml file to wrap_content. android:layout_height="wrap_content"

Try to set the second LinearLayout holding the Listview to match_parent height... It seems like your LinearLayout is growing with the ListView (wrap_content) out of your screen space
