ViewPager not loading properly when user swipes in Android

I have an Android View Pager with five screens with images, autoload pager screen with timer.
When user swipes, it is jumping screens based on timer, and is not loading properly.
I have attached code below.
MainActivity.java
package com.sks.androidviewpager;

import android.view.Menu;
public class MainActivity extends Activity {
int noofsize = 5;
ViewPager myPager = null;
int count = 0;
Timer timer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//set the layout which is containg viewPager Tag for image
setContentView(R.layout.activity_main);
//ViewPager Adapter to set image
ViewPagerAdapter adapter = new ViewPagerAdapter(MainActivity.this,noofsize);
myPager = (ViewPager) findViewById(R.id.reviewpager);
myPager.setAdapter(adapter);
myPager.setCurrentItem(0);
// Timer for auto sliding
timer = new Timer();
timer.schedule(new TimerTask() {
#Override
public void run() {
runOnUiThread(new Runnable() {
#Override
public void run() {
if(count<=5){
myPager.setCurrentItem(count);
count++;
}else{
count = 0;
myPager.setCurrentItem(count);
}
}
});
}
}, 500, 3000);
}
}

Use
myPager.setCurrentItem(myPager.getCurrentItem()+1);
instead of myPager.setCurrentItem(count);
And you should judge if current item is the last item of this view pager.

you should return true instead of false in isEnabled
#Override
public boolean isEnabled(int position) {
return false;
}
From the documentation:
Returns true if the item at the specified position is not a separator.
(A separator is a non-selectable, non-clickable item).

Add below code to your TextView in the XML
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
and try again.
Another simple solution: add android:descendantFocusability="blocksDescendants" to the root viewgroup.

You should add android:focusable="false" for ListView row items to make ListView Clikable. Because the views in the row of ListView gain the focus so ListView is not focusable. So, in your case you can add android:focusable="false" to the TextViews of your ListView row.

I had the same symptoms, and it drove me crazy for a while. Adding android:focusable="false" for the list items as suggested above fixed the problem for me.
But the real issue was that I had set android:textIsSelectable="true" for my list items (in response to a Warning generated by Eclipse); setting android:textIsSelectable="false" fixed the problem for me, and I did not need the android:focusable="false" option at all.

The workaround I found avoid the
AdapterView.OnItemClickListener mMessageClickedHandler=new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
};
on the ListView, but exploit the Adapter constructor that takes a Context as parameter:
myCustomAdapter=new MyCustomAdapter(ActivityName.this,...)
Passing ActivityName.this is possible to cast the Context in the adapter's class as ActivityName in a safe way and use its methods working like callbacks:
((ActivityName)context).activityMethod()
Given that the getView() method of the Adapter class has a position parameter, is possible to pass this value to the activityMethod(int position) in order to know which list item has been pressed into the Activity where the ListView is.

Another solution.
if you have many child-control,and its to trouble to add android:focusable="false" to every child-control,you can add android:descendantFocusability="blocksDescendants" to its parent-control.try it.

I struggled with this for a while - none of the provided solutions worked for me. In the end I found that having a call to getListView() in my onViewCreated() method did the trick, although I have no idea why. This is for a Fragment rather than an Activity; not sure if this makes any difference.
public class NewsListFragment extends ListFragment {
private ListView listView;
...
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
newsListView = getListView();
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// this now works as expected
}
}

I was also struggling with this issue and none of the suggested solutions worked. My problem was that I did an override for onViewCreated but didn't call super.onViewCreated(view, savedInstanceState);. Hopefully this will help someone else so they don't spend hours trying to figure out what's going on.

I struggled as I by mistake put android:inputType="textCapWords" with the textbox after removing it it is fixed

Only the line below worked for me:
android:descendantFocusability="blocksDescendants"
The whole list_view_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<!--android:focusableInTouchMode="false"-->
<!--android:focusable="false"-->
<!--android:clickable="false"-->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:descendantFocusability="blocksDescendants"
android:layout_height="wrap_content">
<CheckBox
android:id="#+id/checkBox_list_view_checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/checkBox_list_view_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
The above is to be used in getView like:
convertView=LayoutInflater.from(getContext())
.inflate(R.layout.list_view_item, parent, false);

How to let a user add and remove items to a ListView?

I am trying to make it so that when a user clicks a button, it pops up a dialog with an EditText and an OK Button. When the user completes, the dialog, it should add the item they just typed in to the ListView. How do I do this?
I will need a large code example; this is my first application.

You'll want to follow the official notepad tutorial example. It's very comprehensive. It does 95% of what you want to do.
http://developer.android.com/resources/tutorials/notepad/index.html

Well here is a sample code. There is a button to add text in list and long press on list item will remove it.
activity_main.xml
<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" >
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="Add Item" />
<ListView
android:id="#+id/list_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
dialog_layout.xml
<?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" >
<EditText
android:id="#+id/edit_box"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:inputType="text" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:orientation="horizontal"
android:weightSum="2" >
<Button
android:id="#+id/button_ok"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="OK" />
<Button
android:id="#+id/button_cancel"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="CANCEL" />
