I have implemented videoview in one of my fragment. It's working fine but there is one problem I am unable to set a loader or progress bar over the videoview. My progressbar is working for the whole screen but I only want it over the videoview so that user can understand that a video is loading.
Below is my java and xml code.Please help me with the solution.
FragmentTwo.java

private static ProgressBar progressBar;
#Override

Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View view= inflater.inflate(R.layout.fragment_two, container, false);
videoview=(VideoView)view.findViewById(R.id.video);
progressBar = (ProgressBar) view.findViewById(R.id.progressBar1);
return view;
}
void storeRecievedUrl(String url){
String VideoURL = url;
System.out.println(VideoURL);
// progressDialog = ProgressDialog.show(getActivity(), "", "Buffering Video...", true);
try {
MediaController mediacontroller = new MediaController(getActivity());
mediacontroller.setAnchorView(videoview);
Uri video = Uri.parse(VideoURL);
videoview.setMediaController(mediacontroller);
videoview.setVideoURI(video);
videoview.start();
progressBar.setVisibility(View.VISIBLE);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
videoview.requestFocus();
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

Please use the following xml to replace your fragment_two.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

android:id="#+id/video"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<ProgressBar
android:id="#+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
/>
</FrameLayout>
Try using RelativeLayout in fragment_two.xml instead of LinearLayout and put your progressbar on top of videoview.

Include this permission in manifest if you are storing pdf in external storage.
Use Asset folder like this
AssetManager assetManager = getAssets();
File file = new File(getFilesDir(), "xyz.pdf");
in = assetManager.open("xyz.pdf");
out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;
You can open it as an input stream like this from a fragment
reader = new BufferedReader(new InputStreamReader(getActivity().getAssets().open(myfile.pdf))
You don't need permisssions as you're accessing your app's internal files but putting pdf into assets can increase the weight of the app , be careful
and then you can save it as string like that
private StringBuilder text = new StringBuilder();
String mLine;
while ((mLine = reader.readLine()) != null) {
text.append(mLine);
text.append('\n');
}
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
//log the exception
}
Basically i have BottomNavigationView activity in that there are 3 fragments (tab1,tab2,tab3) which contain 3 webviews, what i actually wanna to do is while scrolling down the webview my actionbar should hide, likegetSupportActionBar().hide(); i know already there are answers in the stack overflow for the same question, but i don't know what to do in my case, because i am a beginner in android development
here is my activity_main.xml
<?xml version="1.0" encoding="utf-8"?>

This is my first fragment (fragment_tab1)

android:progress="20"/>
</FrameLayout>
<WebView

This is my java code for tab1
package com.hackerinside.jaisonjoseph.polysocial;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;

import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.widget.FrameLayout;
import android.widget.ProgressBar;
/**
* A simple {#link Fragment} subclass.
*/
public class tab1 extends Fragment {
public ProgressBar bar;
public FrameLayout frameLayout;
public tab1() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_tab1, null);
frameLayout=(FrameLayout) rootView.findViewById(R.id.frame1);
bar=(ProgressBar)rootView.findViewById(R.id.progressBar1);
bar.setMax(100);
final WebView view=(WebView) rootView.findViewById(R.id.webview);
view.loadUrl("http://facebook.com");
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyWebViewClient());
view.setWebChromeClient(new WebChromeClient(){
public void onProgressChanged(WebView view1,int progress){
frameLayout.setVisibility(View.VISIBLE);
bar.setProgress(progress);
if (progress==100){
frameLayout.setVisibility(View.GONE);
}
super.onProgressChanged(view1,progress);
}
});
view.getSettings().setBuiltInZoomControls(true);
view.getSettings().setDisplayZoomControls(false);
bar.setProgress(0);
return rootView;
}
}
Here is a sample idea of implementation.
boolean isShowing;
//oncraete code is here
WebView mScrollView = (WebView) findViewById(R.id.scrollView);
mScrollView.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
#Override
public void onScrollChanged() {
float mfloat = mScrollView.getScrollY();
if (mfloat >= tToolbar.getHeight() && isShowing) {
toolbarAnimateHide();
} else if (mfloat == 0 && !isShowing) {
toolbarAnimateShow(0);
}
}
});
private void toolbarAnimateShow(final int verticalOffset) {
isShowing = true;
//tToolbar is your view(any view)
// add getSupportActionBar().hide() this code here to hide actionbar
// remove below code or comment
tToolbar.animate()
.translationY(0)
.setInterpolator(new LinearInterpolator())
.setDuration(180)
.setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationStart(Animator animation) {
toolbarSetElevation(verticalOffset == 0 ? 0 : TOOLBAR_ELEVATION);
}
});
}

But i want the images to come like a stack.. Not exactly overlapped. Refer this
Can anyone help me achieve this?
This is a link with your solution https://github.com/Diolor/Swipecards
Incase you use custom ArrayAdaper on inflating layout this is the code that worked for me
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.swipe_item, parent, false);
I have a fragment with the following layout: my_fragment.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/appName"
android:id="#+id/textView" android:layout_gravity="center"
android:layout_margin="5dp"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button1"
android:id="#+id/button1"
android:layout_gravity="center"/>
and corresponding MyFragment.java
package com.example.appdemo;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;
public class MyFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.top_bar, container, false);
Button button1 = (Button)view.findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Toast.makeText(getActivity(), "Button Pressed", Toast.LENGTH_SHORT).show();
}
});
return view;
}
}
and this is hosted inside MainActivity.java
package com.example.appdemo;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
with the following layout 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"
tools:context=".MainActivity" >
<fragment
android:id="#+id/fragment"
android:name="com.example.appdemo.MyFragment"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
Now, my question is why does this only work when I extend FragmentActivity? I'd like to extend Activity. How do I accomplish that?
Why does this only work inside a host class that extends FragmentActivity?
Because you are inheriting from android.support.v4.app.Fragment instead of android.app.Fragment.
Basically, the code below is what I am using to retrieve images from a remote server. My problem is, whenever I have large images like 700x700, it shrinks the entire image until it only fits the screen. What I really want is whenever I have large image like that, I want it to stay just the way it is and show a vertical and horizontal scrollbar instead. is this possible to accomplish?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<ProgressBar
android:id="#+id/progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageView
android:id="#+id/imageView"
android:visibility="gone"
android:layout_width="200dp"
android:layout_height="200dp"/>
</LinearLayout>
Then my main activity ImageDownload.java
import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;
import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.ImageView;
import android.widget.ProgressBar;
public class ImageDownload extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView mainImageView = (ImageView) findViewById(R.id.imageView);
ProgressBar progressBar = (ProgressBar) findViewById(R.id.progressBar);
String imageurl = "http://4.bp.blogspot.com/-xRyw7I08tDM/TgNqD2Ij-3I/AAAAAAAAAOU/FGjboxE-u2U/s1600/cute_cat_cute_1-s357x422-47520.jpg";
ImageDownloadMessageHandler imageDownloadMessageHandler1= new ImageDownloadMessageHandler(progressBar, mainImageView);
ImageDownlaodThread imageDownlaodThread = new ImageDownlaodThread(imageDownloadMessageHandler1,imageurl);
imageDownlaodThread.start();
}
class ImageDownlaodThread extends Thread {
ImageDownloadMessageHandler imageDownloadMessageHandler;
String imageUrl;
public ImageDownlaodThread(ImageDownloadMessageHandler imageDownloadMessageHandler, String imageUrl) {
this.imageDownloadMessageHandler = imageDownloadMessageHandler;
this.imageUrl = imageUrl;
}
#Override
public void run() {
Drawable drawable = LoadImageFromWebOperations(imageUrl);
Message message = imageDownloadMessageHandler.obtainMessage(1, drawable);
imageDownloadMessageHandler.sendMessage(message);
System.out.println("Message sent");
}
}
class ImageDownloadMessageHandler extends Handler {
ProgressBar progressBar;
View imageTextView;
public ImageDownloadMessageHandler(ProgressBar progressBar, View imageTextView) {
this.progressBar = progressBar;
this.imageTextView = imageTextView;
}
#Override
public void handleMessage(Message message) {
progressBar.setVisibility(View.GONE);
imageTextView.setBackgroundDrawable(((Drawable) message.obj));
imageTextView.setVisibility(View.VISIBLE);
}
}
Drawable LoadImageFromWebOperations(String url) {
Drawable d = null;
InputStream is = null;
try {
is = (InputStream) new URL(url).getContent();
d = Drawable.createFromStream(is, "src name");
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return d;
}
}
Try this:
<ScrollView android:id="#+id/scrollView1"
android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout android:id="#+id/linearLayout1" android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="vertical">
<HorizontalScrollView android:id="#+id/horizontalScrollView1"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<LinearLayout android:id="#+id/linearLayout2"
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="horizontal">
<TextView/>
<ImageView/>
<ProgressBar/>
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
</ScrollView>
This way you can have both vertical and horizontal scroll.
The layout element ScrollView and HorizontalScrollView has been invented for this purpose.
