How i can create paging in my page for epub ? android - java

How i can create paging for my WebView that fill from Epub.
My MainActivity.java :
public class MainActivity extends ActionBarActivity implements OnClickListener {
WebView webView;
Handler hand;
String data = null;
LinearLayout books;
int pagecount = 1;
Book book;
#SuppressLint("SetJavaScriptEnabled")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hand = new Handler();
webView = new WebView(this);
books = (LinearLayout) findViewById(R.id.book);
AssetManager assetManager = getAssets();
try {
InputStream epubInputStream = assetManager.open("mybook.epub");
book = (new EpubReader()).readEpub(epubInputStream);
Log.i("Log_one", "author(s): " + book.getMetadata().getAuthors());
Log.i("Log_two", "title: " + book.getTitle());
Bitmap coverImage = BitmapFactory.decodeStream(book.getCoverImage().getInputStream());
Log.i("Log_three", "Coverimage is " + coverImage.getWidth() + " by " + coverImage.getHeight() + " pixels");
logTableOfContents(book.getTableOfContents().getTocReferences(), 0);
Spine spine = book.getSpine();
List<SpineReference> spineList = spine.getSpineReferences();
int count = spineList.size();
Button btnnext = (Button) findViewById(R.id.btnNext);
Button btnPreviuse = (Button) findViewById(R.id.btnPreviuse);
btnnext.setOnClickListener(this);
btnPreviuse.setOnClickListener(this);
} catch (IOException e) {
Log.e("Log_four", e.getMessage());
}
}
private void logTableOfContents(List<TOCReference> tocReferences, int depth) {
if (tocReferences == null) {
return;
}
for (TOCReference tocReference : tocReferences) {
StringBuilder tocString = new StringBuilder();
for (int i = 0; i < depth; i++) {
tocString.append("\t");
}
tocString.append(tocReference.getTitle());
Log.i("Log_five", tocString.toString());
logTableOfContents(tocReference.getChildren(), depth + 1);
}
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.btnNext) {
try {
int i = pagecount + 7;
webView = new WebView(this);
books = (LinearLayout) findViewById(R.id.book);

Why is recycler giving a strange behaviour with selection?

I have made an Image Editor and it works fine. Now, in my recent edits page, I added a feature select multiple items. But, I get a strange behaviour when I refresh the recycler view. See this ->
https://www.veed.io/view/43fa65a4-24e6-44e8-8cea-468ca8c62d7a.
This is my adapter code ->
public class RecentsAdapter extends RecyclerView.Adapter<RecentsAdapter.ViewHolder>{
private List<ImageFile> files;
private final PopupListener popupListener;
RecentItemListeners recentItemListeners;
public Integer selectedItemsCount = 0;
TextView neEditsTV;
public RecentsAdapter(List<ImageFile> files, PopupListener popupListener, RecentItemListeners listeners, TextView neEditsTV) {
this.files = files;
this.popupListener = popupListener;
this.recentItemListeners = listeners;
this.neEditsTV = neEditsTV;
}
public void updateList(List<ImageFile> filesList){
if (files.size() < filesList.size()){
int dif = filesList.size() - files.size();
this.files = filesList;
for (int i = 0; i < dif; i++) {
notifyItemInserted(i);
}
}else if (files.size() > filesList.size()){
for (int i = 0; i < filesList.size(); i++) {
notifyItemChanged(i);
}
notifyDataSetChanged();
notify();
}else {
this.files = filesList;
for (int i = 0; i < filesList.size(); i++) {
notifyItemChanged(i);
}
}

Your Adapter doesnt seen to be in the same LayoutXML, maybe your findViewById(R.id.btnPlay1) are returning null.

Your listener change it to this :
btnPlay1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(Act.this, "test click", Toast.LENGTH_SHORT).show();
}
});

and the result that I got from looping Utils.log("studio_name: " + studio_name) are :
studio_name: Dodi fit
studio_name: inu fit
studio_name: Vstudio
studio_name: Infovendor
studio_name: Seleb Fitnes One
studio_name: Riri Studio
studio_name: NF Studio
It means I already got all of it use looping.
But the problem is the result did not populate into listview (it show as one one last result NF Studio, the other did not appear).
What I need is populate this into 4 texview from country_info (I disable imageview) :
String studio_name, address, website, seo_url
What is the correct code to show/populate that into listview?

Add the values into a List and pass it to the Adapter class of your ListView inside onPostExecute()

You don't need a thread, that's the whole point of async.
List View code is in the for loop
UI code belongs to PostExecute() not doInBackground()
You reinitialized the list inside of the loop
Try like this:
private class SendfeedbackJob extends AsyncTask<String, Void, String> {
private static final String LOG_TAG = "CariStudio";
private ArrayList<Country> countryList = new ArrayList<Country>();
ProgressDialog dialog;
Bundle extras = getIntent().getExtras();
final String token= extras.getString("TOKEN");
#Override

String areaid = params[0];
Utils.log("params 1:"+ areaid);
// do above Server call here

postParameters.add(new BasicNameValuePair("region_id", areaid ));
String responseString = null;

Utils.log("url studio:"+ url_studio);

How to use ChrisBanes' ActionBar-PullToRefresh library with Tab view at bottom in activity

I am trying to use Chris Banes' library Actionbar-PullToRefresh. It can be found here.

Put all your list views in PullToRefreshLayout and give R.id.tab_1 R.id.tab_2 R.id.tab_3 id's to your PullToRefreshLayout instead of ListView
<uk.co.senab.actionbarpulltorefresh.library.PullToRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tab_1"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/listview1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</uk.co.senab.actionbarpulltorefresh.library.PullToRefreshLayout>
same for rest of the listview
In java inside onCreate of the activity:
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mPullToRefreshLayout= (ListView)findViewById(R.id.tab_1);
mPullToRefreshLayout1 = (ListView)findViewById(R.id.tab_2);
mPullToRefreshLayout2 = (ListView)findViewById(R.id.tab_3);
listview = (ListView)findViewById(R.id.listview1);
listview1 = (ListView)findViewById(R.id.listview2);
listview2 = (ListView)findViewById(R.id.listview3);
ActionBarPullToRefresh.from(this)
// Mark All Children as pullable
.allChildrenArePullable()
// Set the OnRefreshListener
.listener(this)
// Finally commit the setup to our PullToRefreshLayout
.setup(mPullToRefreshLayout);
on tab change:
public void onTabChanged(String tabId) {
for(int i=0;i<mTabHost.getTabWidget().getChildCount();i++)
{
mTabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.WHITE);
}
if (TAB_1.equals(tabId)) {
// updateTab(R.id.tab_1);
mCurrentTab = 0;
//Toast.makeText(getApplicationContext(), "1No Guest list for Today", Toast.LENGTH_SHORT).show();
mTabHost.getTabWidget().getChildAt(mTabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#fff498"));
ActionBarPullToRefresh.from(this)
// Mark All Children as pullable
.allChildrenArePullable()
// Set the OnRefreshListener
.listener(this)
// Finally commit the setup to our PullToRefreshLayout
.setup(mPullToRefreshLayout);
}
if (TAB_2.equals(tabId)) {
//updateTab(R.id.tab_2);
mCurrentTab = 1;
//Toast.makeText(getApplicationContext(), "2No Guest list for Today", Toast.LENGTH_SHORT).show();
mTabHost.getTabWidget().getChildAt(mTabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#fff498"));

}
if (TAB_3.equals(tabId)) {
//updateTab(R.id.tab_2);

Compare two files in android

I have to compare two .txt files. Below is my code..
activity_main.xml
<RelativeLayout 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: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=".MainActivity" >
<Button
android:id="#+id/file1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="File 1" />
<Button
android:id="#+id/file2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/file1"
android:layout_below="#+id/file1"
android:text="File 2" />
<Button
android:id="#+id/compare"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/file2"
android:layout_below="#+id/file2"
android:layout_marginTop="16dp"
android:text="Compare" />
</RelativeLayout>
MainActivity.java
public class MainActivity extends Activity {
FileOutputStream fos;
FileInputStream fOne, fTwo;
ArrayList<String> arr1 = new ArrayList<String>();
ArrayList<String> arr2 = new ArrayList<String>();
int count = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button fileOne = (Button)findViewById(R.id.file1);
Button fileTwo = (Button)findViewById(R.id.file2);
Button compare = (Button)findViewById(R.id.compare);
arr1.add("1");
arr1.add("2");
arr1.add("3");
arr2.add("2");
arr2.add("3");
fileOne.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try
{
fos = openFileOutput("File1", Context.MODE_PRIVATE);
for(int temp = 0; temp< arr1.size(); temp++)
{
fos.write((arr1.get(temp).getBytes()) );
fos.write(System.getProperty("line.separator").getBytes());
}
fos.close();
fos.flush();
}
catch(Exception e)
{
}
}
});
fileTwo.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try
{
fos = openFileOutput("File2", Context.MODE_PRIVATE);
for(int temp = 0; temp< arr2.size(); temp++)
{
fos.write((arr2.get(temp).getBytes()) );
fos.write(System.getProperty("line.separator").getBytes());
}
fos.close();
fos.flush();
}
catch(Exception e)
{
}
}
});
compare.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try
{
fOne = openFileInput("File1");
fTwo = openFileInput("File2");
Scanner scanFileOne = new Scanner(new DataInputStream(fOne));
Scanner scanFileTwo = new Scanner(new DataInputStream(fTwo));
while (scanFileOne.hasNextLine())
{
String first = scanFileOne.next();
String second = scanFileTwo.next();
if(first.equals(second))
{
count++;
}
}
Toast.makeText(getBaseContext(), "" + count, 1000).show();
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
}
});
}
}
What I have to do is on Compare button click, I have to compare content of both files and message should be prompted. But here my app force closes..What needs to be done?

your while loop needs to check that both files have a next line that can be retrieved
while (scanFileOne.hasNextLine() && scanFileTwo.hasNextLine())
