Set Volume mute to unmute on OrientationChange using setStreamMute() method of AudioManager is not working.
Suppose i set Volume mute using setStreamMute(AudioManager.STREAM_MUSIC, true); by clicking on audButton in landscape mode. Then if i change Orientation & trying to set Volume unmute using setStreamMute(AudioManager.STREAM_MUSIC, false) in portrait mode then it is not working. I have allready debug my code, methods to set volume mute/unmute calling correctly.
I am using following given code by clicking on audButton -
audButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
//Log.v("Flip Camera", "Changing Camera Facing");
audIsON = !audIsON;
getAM().setStreamMute(AudioManager.STREAM_MUSIC, audIsON);
if(audIsON == true)
{
audButton.setBackgroundResource(R.drawable.speaker_volum_icon_mute);
}
else
{
audButton.setBackgroundResource(R.drawable.speaker_volum_icon);
}
//((SurveillanceApplication)getApplication()).setMute(audIsON);
}
});
Thanks in advance :)

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 :

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'm searching for ways to implement a swipe gesture recognizer which only triggers when you swipe from the outer left side of the screen to the right. We need the gesture to open our custom SideMenu. I tried to use a simple UISwipeGestureRecognizer with the SwipeDirection property set to right, but that gets triggered on every swipe from left to right, no matter what the startpoint of the swipe is.
Ideally, we want the animation of it to look and feel like the InteractivePopGestureRecognizer of a UINavigationController. We are already using a NavigationController, which pushed our MainView over our IntroView. Now, we disable the InteractivePopGestureRecognizer, so you aren't able to go back to the IntroView. That's our problem. If it is possible, we don't want to disable the gesture of the NavigationController, but change the action of it. So the swipe from the far left side of the screen to the right would not pop the current viewcontroller, but open our SideMenu.
Is it possible to override the InteractivePopGestureRecognizer to change the action of it? If this isn't possible, do you have another idea on how to create the exact same gesture recognizer? It has to be possible somehow because many apps only open their SideMenu if your startpoint of the gesture is the left (or right) side of the screen. (e.g. Reddit)
Thanks for any help in advance.
You could use Touch Events and UISwipeGestureRecognizer to do that.
The workaround that is override TouchesBegan method to detect the started point whether fit your needs, and if so add UISwipeGestureRecognizer for View.
SwipeGestureRecognizer rightSwipeGesture;
public override void TouchesBegan (NSSet touches, UIEvent evt)
{
base.TouchesBegan (touches, evt);
UITouch touch = touches.AnyObject as UITouch;
if (touch != null)
{
//code here to handle touch
CoreGraphics.CGPoint swipPoint = touch.LocationInView(View);
if(swipPoint.X < 0.5)
{
rightSwipeGesture = new SwipeGestureRecognizer { Direction = SwipeDirection.Right };
rightSwipeGesture.Swiped += OnSwiped;
View.AddGestureRecognizers(rightSwipeGesture);
}
}
}
public override void TouchesEnded (NSSet touches, UIEvent evt)
{
base.TouchesBegan (touches, evt);
if(null != rightSwipeGesture ){
rightSwipeGesture.Swiped -= OnSwiped;
View.RemoveGestureRecognizers(rightSwipeGesture);
}
}
=============================Update=================================
I found a workaround only use one GestureRecognizer will make it works. You could have a look at UIScreenEdgePanGestureRecognizer. Although it's a Pan gesture, however if you not deal with somethind with the added view, it will work as a swip gesture. In addition, UIScreenEdgePanGestureRecognizer only can work when on the screen edge. You could set the Left edge to handle your needs.
For example:
UIScreenEdgePanGestureRecognizer panRightGestureRecognizer = new UIScreenEdgePanGestureRecognizer();
panRightGestureRecognizer.Edges = UIRectEdge.Left;
panRightGestureRecognizer.AddTarget(() => HandleSwap(panRightGestureRecognizer));
View.AddGestureRecognizer(panRightGestureRecognizer);
private void HandleSwip(UIScreenEdgePanGestureRecognizer panRightGestureRecognizer)
{
Point point = (Point)panRightGestureRecognizer.TranslationInView(View);
if (panRightGestureRecognizer.State == UGestureRecognizerState.Began)
{
Console.WriteLine("Show slider view");
}
}
google youtube player using
#Override
public void onInitializationSuccess(Provider arg0, YouTubePlayer player,
boolean restored) {
// TODO Auto-generated method stub
player.setFullscreenControlFlags(YouTubePlayer.FULLSCREEN_FLAG_CONTROL_ORIENTATION);
//This flag tells the player to automatically enter fullscreen when in landscape. Since we don't have
//landscape layout for this activity, this is a good way to allow the user rotate the video player.
player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE);
if(!restored){ //lnIEn0kWdhY
player.cueVideo(getIntent().getStringExtra("VIDEO_ID"));
//player.cueVideo("lnIEn0kWdhY");
//player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
}
else {
Log.e("dd","dff");
}
}
Use the minimal video player style to hide the youtube icon. But it will show only timer bar play/pause controls.
player.setPlayerStyle(YouTubePlayer.PlayerStyle.MINIMAL);
I have a project with 2 activities, the first one is the "SplashActivity" - where I load some network data - the second one, the MainActivity.
Inside of my MainActivity I have a fragment and inside of this fragment a webview. My first point is, when the user clicks on back button, the SplashScreen is open again.
The back button should behave like:
When the user doesn't navigate inside of my webview, close the app.
When the user navigates in webview, use the back history of the browswer.
I read about back stack here: http://developer.android.com/training/implementing-navigation/temporal.html#back-webviews
I didn't understand at all how it should work, because I have all cases "mixed". Anyone knows what should I do to fix this problem?
Any idea or sample code will be appreciate!
Define Webview wb as a global variable. Then try this;
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_DOWN){
switch(keyCode)
{
case KeyEvent.KEYCODE_BACK:
if(wb.canGoBack() == true){
wb.goBack();
}else{
new AlertDialog.Builder(this).setIcon(android.R.drawable.ic_dialog_alert).setTitle("Application will be closed")
.setMessage("Close app?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
finish();
System.exit(0);
}
}).setNegativeButton("No", null).show();
}
return true;
}
}
return super.onKeyDown(keyCode, event);
}
}
I did the following but it not work for always.It works if i launch the app manually and then turn off the device and turn on the device my app is launched. But before turning off the device if i switched to another app then after switch-on the device,"My app is not getting launch".
import net.rim.device.api.system.ApplicationDescriptor;
import net.rim.device.api.system.ApplicationManager;
import net.rim.device.api.ui.UiApplication;
public class MyApp extends UiApplication
{
public static void main(String args[]) {
if (args.length == 0)
{
ApplicationDescriptor current = ApplicationDescriptor.currentApplicationDescriptor();
current.setPowerOnBehavior(ApplicationDescriptor.POWER_ON);
ApplicationManager manager = ApplicationManager.getApplicationManager();
manager.scheduleApplication(current, System.currentTimeMillis()
+ 2000, true);
}
System.out.println("restarted !");
MyApp app = new MyApp();
app.enterEventDispatcher();
}
public MyApp()
{
pushScreen(new MyScreen());
}
}
Please help..........it's important...and thanks a lot.
Im not a blackberry expert, but I develop for iOS and Android. The on/off switch or power button is hardly linked to the device, and the action performed when it's pressed is written in the operating system, not in an application, I don't think you'll find an event listener for this button to be pressed, just imagine the security issues it could raise if an app could prevent the phone from turning off (or on ...)
In your Eclipse project, open the Blackberry_App_Description.xml file, go to the "Alternate Entry Points" tab, add a new entry to the list, enable its "Auto-run on startup" option, and give it an "Application argument" value of your choosing. You can then update your main() function to look for that value when the app runs:
public static void main(String args[])
{
if ((args != null) && (args.length > 0) && (args[0].equals("MyValue")))
{
System.out.println("System Startup !");
}
MyApp app = new MyApp();
app.enterEventDispatcher();
}
On android its totally possible. You only have to register a broadcast receiver with the correct filter and add the permission on the manifest.
I think you should not think of this function from the buttons point of view and more on the power on event point of view.
