ViewPager not loading properly when user swipes in Android

ViewPager not loading properly when user swipes in Android - 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 java.util.Timer;
import java.util.TimerTask;
import com.androidsurya.androidviewpager.R;

import android.os.Bundle;
import android.support.v4.view.ViewPager;
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.

When I apply OnItemClickListener it does not do any action like intent inside the func not called. I tried toast too but nothing shown on clicking the listView Items.
I also tried OnItemSlectedListener , it also not worked for me.
What is the problem here with this code. ?

Thanks Every One. Issue was with autolink on email and phone, I make their focusable=false but nothing happened.Then I remove it and guess what? Clicklistener also starts working.

The attribute android:clickable="true" in your ListView could be overriding all of click events of its child views, you should probably remove it:
<ListView
android:clickable="true" <!-- Remove this attribute -->
android:id="#+id/listView_emp_directory_xml"
android:layout_below="#id/relatice_layout_header_emp_directory_activity_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

ViewPager doesn't appear

I'm trying to display my ViewPager since few times without success.
In fact, my fragment layout (which contains the ViewPager) is cut in two parts with weight.
When I check the preview of the Adapter, I see what I want, which is not the case when the application is launched.
This is the code of my Fragment :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_search, container, false);
if (this.getArguments().getString("search") != null) {
final List<Produit> produitList =
HypredDbManager.getDbManager().getProduitDbManager()
.getProduitsByString(this.getArguments().getString("search"));
String product = Integer.toString(produitList.size()) + " ";
if (produitList.size() > 1) {
product += getResources().getString(R.string.products);
} else {
product += getResources().getString(R.string.product);
}
((TextView) rootView.findViewById(R.id.search_nombre_produits)).setText(product);
ArrayList<View> viewArrayList = new ArrayList<>();
for (int i = 0; i < produitList.size(); i++) {
ProduitItem produitItem = new ProduitItem(rootView.getContext(), produitList.get(i));
produitItem.setProduitItemListener(new ProduitItem.produitItemListener() {
#Override
public void onProduitSelected(Produit produit) {
mCallback.changeFragment(produit);
}
#Override
public void ajoutPanier(Produit produit) {
SelectionManager.getInstance().addProductToSelection(rootView.getContext(), ProduitSelectionne.fromProduitAndHistorique(produit, ""));
}
});
viewArrayList.add(produitItem);
}
HypredTableLayout hypredTableLayout = (HypredTableLayout) rootView.findViewById(R.id.search_tablelayout_produit);
hypredTableLayout.addChild(viewArrayList, 2, this);
final ArrayList<Protocole> protocoles = new ArrayList<>();
protocoles.addAll(HypredDbManager.getDbManager().getProtocoleDbManager()
.getProtocolesByString(this.getArguments().getString("search")));
String protocole = Integer.toString(protocoles.size()) + " ";
if (protocoles.size() > 1) {
protocole += getResources().getString(R.string.protocoles);
} else {
protocole += getResources().getString(R.string.protocole);
}
((TextView) rootView.findViewById(R.id.search_nombre_protocoles)).setText(protocole);
Log.d(TAG, "protocoles : " + protocoles.size());
if(protocoles.size()> 0) {
ViewPager viewPagerProtocole = (ViewPager) rootView.findViewById(R.id.search_viewpager_protocole);
ProtocoleAdapterViewPager protocoleAdapterViewPager = new ProtocoleAdapterViewPager(rootView.getContext(), protocoles);
protocoleAdapterViewPager.setClickOnProductListener(new ProtocoleAdapterViewPager.clickOnProductListener() {
#Override
public void appelProduit(long productId) {
mCallback.changeFragment(HypredDbManager.getDbManager().getProduitDbManager().getProduitById(productId));
}
#Override
public void ajouterAllProduit(ArrayList<Produit> produitArrayList) {
for (int i = 0; i < produitArrayList.size(); i++) {
SelectionManager.getInstance().addProductToSelection(getActivity(), ProduitSelectionne.fromProduitAndHistorique(produitArrayList.get(i), ""));
}
}
#Override
public void ajouterProduit(Produit produit) {
SelectionManager.getInstance().addProductToSelection(getActivity(), ProduitSelectionne.fromProduitAndHistorique(produit, ""));
}
});
viewPagerProtocole.setAdapter(protocoleAdapterViewPager);
viewPagerProtocole.setCurrentItem(0);
Log.d(TAG, "protocoleAdapterViewPager : " + protocoleAdapterViewPager.getCount());
Log.d(TAG, "getcurrentitem : " + viewPagerProtocole.getCurrentItem());
}
}
return rootView;
}
The getCount of my Adapter return the right size.

</LinearLayout>
In this LinearLayout you have android:orientation="horizontal", but you set to your TextView android:layout_width="match_parent". So, in this case your TextView fill out all LinearLayout and there no free space for your ViewPager.
It seems, that's the reason why ViewPager doesn't appear.
Maybe LinearLayout orientation should be vertical.

when I load ListView contain zero record empty list view not showed
Any help will appreciate thanks

Well, i wrote simple it will help you
Override onContentChanged() method
Like below:
#Override
public void onContentChanged() {
super.onContentChanged();
// write you code here, when list view empty.
}

Change the following:
mListview.setEmptyView(getActivity().
findViewById(R.id.emptyElement));
mListview.setAdapter(mAdapter);
to
mListview.setAdapter(mAdapter);
mListview.setEmptyView(getActivity(). findViewById(R.id.emptyElement));
Bind the listview first and then set the empty view.

Place the
mListview.setEmptyView(getActivity(). findViewById(R.id.emptyElement));
below
mListview.setAdapter(mAdapter);

Image not displayed in listview

Went through many demos and was not able to figure out how to get the imageview work in list view.
Tried the code however the image is not visible in listview. Other details are working fine in the list view

Kindly help me out.
Thanks in anticipation.

Can you please paste your activity_main.xml? Moreso, it is preferable you use actionbar tabs.

Just changed position of layout and it stopped working
Clean and rebuild. Likely your resource ids in binary XML files and R.java are out of sync.
Now that you've included logcat, java.lang.ClassCastException: android.widget.ImageView cannot be cast to android.widget.TextView in detail() are also indicative of this - the resource ids you're passing to the method are valid TextViews but at least in one case it is referring to an ImageView in binary XML.

the mistake is in MyBaseAdapter.java
simple mistake, parameters mismatched.
insted of
private ImageView idetail(View v,int resId,int icon)
{
ImageView iv=(ImageView) v.findViewById(resId);
iv.setImageResource(resId);
return iv;
}
we need to change it to
private ImageView idetail(View v,int resId,int icon)
{
ImageView iv=(ImageView) v.findViewById(R.id.icon);
iv.setImageResource(icon);
return iv;
}

Duplicate Items Added To Gridlayout Using Custom ButtonAdapter Extends BaseAdapter

I need some help on this issue. When I added items to grid layout, some duplicate items added to container and when scrolling their positions are changing. Here is the XML and Java code.
Layout:
<RelativeLayout

Please let me know why some duplicate items added instead of actual items. While scrolling their positions have changed.

remove the condition and ready
