Video on full screen in WebView

can someone help me please? I want a simple method to just enable fullscreen on a video being played in my WebView by simple tapping the video two times or having the fullscreen mode icon in the video player.
Here what I have:
package com.orb.tvdroid;
import android.app.Activity;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;

public class TVDroid extends AppCompatActivity {
WebView TVDroid;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tv_droid);
final Activity activity = this;
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.mipmap.ic_launcher);
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#007f00")));
Toast.makeText(getApplicationContext(), "Espere o carregamento da página completar.", Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(), "Em seguida, escolha um dos canais disponíveis para começar a transmissão.", Toast.LENGTH_LONG).show();
final String link = this.getIntent().getStringExtra("Link");
TVDroid = (WebView) findViewById(R.id.TVdroid);
this.registerForContextMenu(TVDroid);
WebSettings webSettings = TVDroid.getSettings();
webSettings.setJavaScriptEnabled(true);
TVDroid.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progresso) {
activity.setTitle("TVDroid... " + progresso + "%");
activity.setProgress(progresso * 100);
if (progresso == 100)
activity.setTitle("TVDroid");
}
});
TVDroid.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return true;
}
});
TVDroid.loadUrl(link);
}
}
I already looked into many solutions here, but many of them seems a bit too much for what I want to do. I dont want a full video player function, all I want is just being able to double tap the video player and set it on full screen on my app.
Thanks in advance.
Just did it guys, Thanks Vishal for your idea, here is the final onCreate:
WebView TVDroid;
ProgressDialog carregando;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fullscreen);
this.setTitle("TVDroid");
carregando = new ProgressDialog(TVDroid.this);
carregando.show();
mVisible = true;
mControlsView = findViewById(R.id.fullscreen_content_controls);
mContentView = findViewById(R.id.fullscreen_content);
mContentView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
toggle();
}
});
final Activity activity = this;
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.mipmap.ic_launcher);
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#007f00")));
Toast.makeText(getApplicationContext(), "Espere o carregamento da página completar.", Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(), "Em seguida, escolha um dos canais disponíveis para começar a transmissão.", Toast.LENGTH_LONG).show();
final String link = this.getIntent().getStringExtra("Link");
TVDroid = (WebView) findViewById(R.id.TVdroid);
TVDroid.getSettings().setJavaScriptEnabled(true);
TVDroid.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
TVDroid.loadUrl("javascript:(function() { " +
"var head = document.getElementsByTagName('header')[0];"
+ "head.parentNode.removeChild(head);" +
"})()");
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return true;
}
});
TVDroid.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progresso) {
carregando.setMessage("Carregando página: " + progresso + "%");
activity.setProgress(progresso * 100);
if (progresso == 100)
carregando.dismiss();
}
});
TVDroid.loadUrl(link);
}

Try this -
Create a new FullscreenActivity -
File -> New -> Activity -> FullscreenActivity
Copy your TVDroid activity code in to FullscreenActivity.

Android Async Task freeze the UI

Hi I have an Activity which user open upon click on a TAB. Actually I have a ViewGroup and Tabactivity as Main Activity. on the first tab I have three activity.
Now in an activity I have a list view (custom) populating on Oncreate and a ViewFlipper (only adding view) in Onresume using AsyncTask.
In that asynctask in Pre Execute if I add code for loader it gives error. Also If I do not show the loader the screen is freezing until the Async task finished.
I actually want to load the list view first and then in background run the async task with a loader. Also does not want to freeze the screen.

How do I reuse the image that is already imported to the detail view of this RSS Fragment

I have this code that receives the RSS feed and displays it into a Row, however, it does not carry over the image once the row has been clicked. How do I achieve this image transfer from the list view to the detailed view.
This is the RSS Reader View

You can send Image via Intent as ByteArray or try loading from URL. Loading from URL is preferred as it will not bring OutOfMemoryException or any other issues while passing large bitmap images via Intent. If image is small, you may pass them via Intent.
The code below shows both the methods. Implement which suits your need or works in your URL case.
Sender Activity
//Download image from thumbUrl to bitmap
URL newurl = new URL(myRssFeed.getItem(position).getThumburl());
Bitmap bitmap = BitmapFactory.decodeStream(newurl.openConnection() .getInputStream());
Intent intent = new Intent(mAct, RssDetailActivity.class);
Bundle bundle = new Bundle();
bundle.putString("keyTitle", myRssFeed.getItem(position).getTitle());
bundle.putString("keyDescription", myRssFeed.getItem(position).getDescription());
bundle.putString("keyLink", myRssFeed.getItem(position).getLink());
bundle.putString("keyPubdate",myRssFeed.getItem(position).getPubdate());
//pass image url
bundle.putString("keyThumburl", myRssFeed.getItem(position).getThumburl());
//sent image bitmap byte array
ByteArrayOutputStream bs = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 50, bs);
bundle.putByteArray("byteArray", bs.toByteArray());
intent.putExtras(bundle);
startActivity(intent);
Receiver Activity
Bundle bundle = this.getIntent().getExtras();
//load from bitmap bytearray
Bitmap bitmap = BitmapFactory.decodeByteArray(bundle.getByteArray("byteArray"),0,bundle.getByteArray("byteArray").length);
imageView.setImageBitmap(bitmap);
//or load from image url
new LoadImage().execute(bundle.getString("keyThumbUrl"));
Create an AsyncTask to load image to ImageView from URL sent via Intent
private class LoadImage extends AsyncTask<String, String, Bitmap> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
protected Bitmap doInBackground(String... args) {
try {
Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(args[0]).getContent());
} catch (Exception e) {
e.printStackTrace();
}
return bitmap;
}
protected void onPostExecute(Bitmap image) {
if(image != null){
imageView.setImageBitmap(image);
} else{
Toast.makeText(RssDetailActivity.this, "Image Does Not exist or Network Error", Toast.LENGTH_SHORT).show();
}
}
}
}

Two activities sending data to each other

Two activities are sending data to each other.
The first activity has a custom list view. The second has one text view and three buttons to increase and decrease a value.
When I click on the first activity, the second activity opens. The second activity increases the text view value and clicked the button. Data goes to the first activity. Same process again.
My problem is that the total value is not displayed in the first activity.
How can i show all increase and decrease values from the second activity in the first activity?

Android ObserveableScrollView to load more (loading issue)

I am fetching information from the website in JSON Format and displaying that info into my app using AsynTask. The Problem is that on On First time my Progress dialog shows well and hide after loading contents into app. But When i use Scroll-view to load more then progress dialog appears and hide after loading immediately at the same time progress dialog opens again and not hiding and Scroll-View loads data one more time in the background.I want only one time to load data after each using Scroll-View to load more. Progress Dialog is not hiding and It keeps running my app. I am struck at this point.
Basically i noticed that My Scroll-View indicator collide two times on the bottom due to this scroll-View trigger two times. How can i stop it and restrict this only one time after each scrolling.
And one more thing wanna share that everything is working awesome in Froyo 2.2 and not working in 2.3 to 4.2. Kindly help me on this. Thanks in advance.

I have Solved this issue and want to share with the future readers. I made a switch and add cases now the new Scroll-View trigger can not run until the previous data will not complete loads.
Here is the final code and hope will help you friends. Thanks
