I'm using barteksc pdf viewer library to load pdf in my application.
pdfView = findViewById(R.id.pdfView);
pdfView.fromAsset(getResources().getString(R.string.pdfname))
.enableDoubletap(true)
.enableSwipe(true)
.defaultPage(pageNumber)
.onPageChange(mainreading.this)
.pageFitPolicy(FitPolicy.WIDTH)
.pageFling(true)
.linkHandler(null)
.enableAnnotationRendering(true)
.swipeHorizontal(true)
.scrollHandle(new DefaultScrollHandlenew(mainreading.this))
.enableAntialiasing(true)
.load();
}
I want pdf to start scroll automatically when user click the button of volume up and down buttons to start stop. I tried with below code while wrapping it in the handler with handler.performClick(); but it shows blank screen while scrolling up and down.
scrollbutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pdfView.scrollTo(0, pdfView.getScrollY() + 24);
}
});
Example :
https://play.google.com/store/apps/details?id=com.emptysheet.pdfreader_autoscroll&hl=en&gl=US
I want to make as like this. Can anyone help please.
Also tried with this. But it shows blank page after some scrolls.
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
int action = event.getAction();
int keyCode = event.getKeyCode();
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_UP:
if (action == KeyEvent.ACTION_DOWN) {
pdfView.scrollTo(0, pdfView.getScrollY() -24);
}
return true;
case KeyEvent.KEYCODE_VOLUME_DOWN:
if (action == KeyEvent.ACTION_DOWN) {
pdfView.scrollTo(0, pdfView.getScrollY() + 24);
}
return true;
default:
return super.dispatchKeyEvent(event);
}
}
You can simply use this PDF viewer from github.
It's based on the same 'barsteksc' pdf viewer with the feature to jump to any pages.
It's MagicalPdfViewer and you can use 'jumpTo(pageNo)' method to simply jump to the specific page. It also gives you the option to animate to the specific page with the same method, just pass 'true' as the 2nd parameter.
Moreover, if you pass the values like '-1' and 'bigger than pageNo', It will automatically scroll to the 0 & last page respectively.
Give it a try & let me know if you got what you wanted.
I am having an issue with displaying a toast message. I want it to display when a button is initially clicked, so that the user is aware the app is working( in my case, generating a QR code). If I place the toast at the beginning of the try catch it does not display right away when the button is clicked. It displays the toast only after the QR code is generated and displayed. Furthermore, the toast is displayed(after QR code is displayed) on my Android emulator but not at all on my physical android device(I have allowed app permissions) if I place it at the beginning of the try catch. It will only display on my physical device if the toast is at the end of the try catch. This has me puzzled. I attempted to use a ProgressBar that would run on the button click and terminate after the QR code was displayed but found this difficult to implement. I thought the toast would be an easy alternative as I have used them through out my project without any issues until now. If anyone can help me understand how I can get the toast to display right away when the button is clicked instead of displaying after the QR code is generated and displayed, it would much appreciated. Alternatively, if someone could assist me with including a progress bar(circle) to run once the button is clicked and stop once the QR code is displayed that would also be very much appreciated, as I believe this would be the most ideal solution.
Please see code below:
public class Generate extends AppCompatActivity {
public final static int QRcodeWidth = 500 ;
private static final String IMAGE_DIRECTORY = "/QR_Code_Generated";
Bitmap bitmap;
private EditText etQr;
private ImageView ivGenerated;
private Button btn;
private Button clrBtn;
private Button shareBtn;
private ProgressBar progressBar;
private int progressStatus = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_generate);
ivGenerated = (ImageView) findViewById(R.id.iv_generated);
etQr = (EditText) findViewById(R.id.generate_input);
btn = (Button) findViewById(R.id.button);
clrBtn = (Button) findViewById(R.id.clearButton);
shareBtn = (Button) findViewById(R.id.shareButton);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (etQr.getText().toString().trim().length() == 0) {
} else {
try {
Toast toast1 = Toast.makeText(Generate.this, "Please Wait, Your QR Code is Generating & will be Saved to your Device... ", Toast.LENGTH_SHORT);
toast1.show();
bitmap = TextToImageEncode(etQr.getText().toString());
ivGenerated.setImageBitmap(bitmap);
String path = saveImage(bitmap); //give read write permission
// Toast.makeText(Generate.this, "QR Code saved to -> " + path, Toast.LENGTH_SHORT).show(); (if I include this second toast it does not display the first toast1)
} catch (WriterException e) {
e.printStackTrace();
}
}
}
});
I dont find any issue with your code for toast pop up, you can try adding a delay of 250ms after toast.show(), maybe it . would be a work around for you.
And for progress bar, its very simple. Create a progress bar in your .xlm file n place it at the center of your View.Layout you willing to show it & make its visibility as FALSE.
You can try this,
progressbar = = (ProgressBar) findViewById(R.id.progressbar);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
progressbar.setVisibility(VISIBLE); // or try View.VISIBLE
if (etQr.getText().toString().trim().length() == 0) {
} else {
try {
Toast toast1 = Toast.makeText(Generate.this, "Please Wait, Your QR Code is Generating & will be Saved to your Device... ", Toast.LENGTH_SHORT);
toast1.show();
bitmap = TextToImageEncode(etQr.getText().toString());
ivGenerated.setImageBitmap(bitmap);
String path = saveImage(bitmap); //give read write permission
// Toast.makeText(Generate.this, "QR Code saved to -> " + path, Toast.LENGTH_SHORT).show(); (if I include this second toast it does not display the first toast1)
} catch (WriterException e) {
e.printStackTrace();
}
finally {
progressbar.setVisibility(INVISIBLE); // or try View.INVISIBLE
}
}
}
});
I'm trying to make an android app with two toolbar in activity. I make two toolbar so I can add action to each fragment activity. But I got trouble.
Well, I can replace the top toolbar when the other fragment showing off with this code:
public override void OnCreateOptionsMenu(IMenu menu, MenuInflater inflater)
{
//SearchMenu
inflater.Inflate(Resource.Menu.nav_search, menu);
var searchItem = menu.FindItem(Resource.Id.action_search);
var provider = MenuItemCompat.GetActionView(searchItem);
mSearchView = provider.JavaCast<Android.Support.V7.Widget.SearchView>();
mSearchView.QueryTextSubmit += (sender, args) =>
{
Toast.MakeText(this.Activity, "You searched: " + args.Query, ToastLength.Short).Show();
};
}
And it works perfectly. And I tried add option menu on second toolbar and ended like this:
public override void OnCreateOptionsMenu(IMenu menu, MenuInflater inflater)
{
//SearchMenu
inflater.Inflate(Resource.Menu.nav_search, menu);
var searchItem = menu.FindItem(Resource.Id.action_search);
var provider = MenuItemCompat.GetActionView(searchItem);
mSearchView = provider.JavaCast<Android.Support.V7.Widget.SearchView>();
mSearchView.QueryTextSubmit += (sender, args) =>
{
Toast.MakeText(this.Activity, "You searched: " + args.Query, ToastLength.Short).Show();
};
//ActionMenu
var mBottomToolbar = this.Activity.FindViewById<Android.Widget.Toolbar>(Resource.Id.secondToolbar);
mBottomToolbar.InflateMenu(Resource.Menu.nav_manageLocation);
mBottomToolbar.MenuItemClick += (sender, e) =>
{
switch (e.Item.ToString())
{
case "Add":
ReplaceFragment(new LocationAddFragment(), "addlocation");
break;
}
base.OnCreateOptionsMenu(menu, inflater);
};
}
Well the nav_manageLocation added to second toolbar. But It wont replace the old second toolbar. So now I got two menu in the second toolbar the old and the new one.
Is there a way so I only can show only the new menu on second toolbar?
Thanks.
I implemented floating button with this thread : How to achieve Floating Action Button in Codenameone?
but I have an layout issue. THe content doesn want to fill the screen. Here the screenshot :
Here how I created the content :
final Container paneContainer = new Container(new LayeredLayout());
private Container getBottomContainer(Form parent) {
newsfeedContainer.setLayout(new BoxLayout(BoxLayout.Y_AXIS));
newsfeedContainer.setScrollableY(true);
loadData();
newsfeedContainer.addPullToRefresh(new Runnable() {
public void run() {
loadData();
}
});
//newsfeedContainer.add(new Button("Button")).add(new Button("Button")).add(new Button("Button")).add(new Button("Button")).add(new Button("Button"));
return newsfeedContainer;
}
private Container getUpperContainer(Form par) {
FlowLayout flow = new FlowLayout(Component.RIGHT);
flow.setValign(Component.BOTTOM);
Container conUpper = new Container(flow);
Button plus = new Button();
FontImage.setMaterialIcon(plus, FontImage.MATERIAL_ADD, 5);
plus.addActionListener((ActionEvent evt) -> {
Form f = new PostComment().commentForm(parent);
f.getToolbar().setBackCommand(parent.getTitle(), BACK_POLICY, e -> parent.showBack());
f.show();
});
conUpper.addComponent(plus);
conUpper.setScrollableX(false);
conUpper.setScrollableY(false);
return conUpper;
}
public Container getContainer(Form parent) {
this.parent = parent;
paneContainer.setScrollableY(false);
paneContainer.addComponent(BorderLayout.center(getBottomContainer(parent)));
paneContainer.addComponent(BorderLayout.south(getUpperContainer(parent)));
return paneContainer;
}
How to make the container fill the screen and make the 'plus' button in the bottom right properly?
Make your Form BorderLayout and place the paneContainer in the center

1)I had the same problem and I solved it by overriding Keyreleased of the Form not the Tab
and inside it I check for the component that is focused and if it is the Tab get "tab.selectedIndex" to detect in which Tab I am and load appropriate data .
Here is Sample code(this inside the my derived form that extends Form )
**
public void keyReleased(int keyCode) {
Component p=this.getFocused();
String str= p.getClass().getName();
if(str.toLowerCase().indexOf("radiobutton")!=-1){ // Radiobutton because when u
Here do tab specific work focus on the
tab it returns radiobutton.
lwuit understands tabs as list
of radiobuttons
}**
2)and about refreshing the data I did a solution and I don't Know if its right
I get the new data , create new List and remove the old one and attach the new one then
call Form.repaint();
