How to open WebView when click on Card View

I trying to open WebView when I click on Card View. The WebView is implemented in Main Activity. It is not working. I am new in coding. This is the Dashboard Activity 👇. Please tell me how can I solve the problem.
public class DashBoardActivity extends MainActivity implements View.OnClickListener {
public CardView card1, card2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( activity_dashboard );
card1 = findViewById( R.id.c1 );
card2 = findViewById( R.id.c2 );
card1.setOnClickListener( this );
card2.setOnClickListener( this );
}
#Override
public void onClick(View v) {
int id = v.getId();
if (id == R.id.nav_home1) {
web_view( "example1.com" );
} else if (id == R.id.nav_home2) {
web_view( "example2.com");
}
}
}

You don't need to extend your Main Activity.
Just pass the URL in Intent Extras to your Main Activity and start it there.
#Override
public void onClick(View v) {
Intent intent = new Intent(this, MainActivity.class);
String example1 = "example1.com";
String example2="example2.com";
int id = v.getId();
if (id == R.id.nav_home1) {
intent.putExtra("URL", example1);
} else if (id == R.id.nav_home2) {
intent.putExtra("URL", example2);
}
startActivity(intent);
}
Then retrieve these extras in your onCreate MainActivity
private WebView wv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String url;
if (savedInstanceState == null) {
Bundle extras = getIntent().getExtras();
if(extras == null) {
url= null;
} else {
url= extras.getString("URL");
}
} else {
url= (String) savedInstanceState.getSerializable("URL");
}
wv1=(WebView)findViewById(R.id.webView);
wv1.setWebViewClient(new MyBrowser());
wv1.getSettings().setLoadsImagesAutomatically(true);
wv1.getSettings().setJavaScriptEnabled(true);
wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv1.loadUrl(url);
}

How to get the data from server and upload data to server using Json

How to get the data from server and upload data to server using JSON?
please tell me.
This is QRActivity------------------------------------------------
final View.OnClickListener listener = new View.OnClickListener() {
#Override
public
void onClick(View v) {
btnSearch.setClickable(true);
// Server call with record_id
//DistributionDetails detDis <-- response json object from server call
QrActivityViewDetails detDis = new
QrActivityViewDetails(1002,"NORORG147530","No2,abcd Road , Colombo 03","0112233456");
Intent myIntent = new Intent(QrActivity.this, DistributionDetails.class);
myIntent.putExtra("QrActivityViewDetails", detDis);
startActivity(myIntent);
}
};
This is QrActivityViewDetails Class file
public class QrActivityViewDetails implements Serializable {
#SerializedName("DistributionID")
private int DistributionID;
#SerializedName("full_name")
private String full_name;
#SerializedName("full_address")
private String full_address;
#SerializedName("contact")
private String contact;
public QrActivityViewDetails(int DistributionID, String full_name, String full_address, String contact_number)
{
this.DistributionID = DistributionID;
this.full_name = full_name;
this.full_address = full_address;
this.contact = contact_number;
}
public
int getRecord_id() {
return DistributionID;
}
public
void setRecord_id(int record_id) {
this.DistributionID = record_id;
}
public
String getFull_name() {
return full_name;
}
public

this.full_address = full_address;
}
public
String getContact() {
return contact;
}
public
void setContact(String contact) {
this.contact = contact;
}
}
This is View Data Activity called DistributionDetails---------------
public class DistributionDetails extends AppCompatActivity {
private QrActivityViewDetails detQRV;
TextView ID ,Address ,name,contact;
Button btnDIR;
#Override
protected
void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

name = (TextView) findViewById(R.id.lblUname);
contact = (TextView) findViewById(R.id.lblTelenum);
btnDIR = (Button) findViewById(R.id.btnDelivered);
IntendFill();
btnDIR.setOnClickListener(new View.OnClickListener() {
#Override
public
void onClick(View v) {
Intent intent = new Intent(DistributionDetails.this, FinalActivity.class);
startActivity(intent);
}
});
}
public void IntendFill() {
Intent intent = getIntent();
if (intent.hasExtra("QrActivityViewDetails")) {
detQRV = (QrActivityViewDetails) intent.getSerializableExtra("QrActivityViewDetails");
ID.setText(String.valueOf(detQRV.getRecord_id()));

contact.setText(String.valueOf(detQRV.getContact()));
}
}
}

pass multiple data on other activity from listview by useof firebase

I created a simple status Shayari application.
This is my first activity in which I retrieve data from Firebase in list view then I take custom text view so on text view click I open another activity name is--> Display_Full_Screen activity. In my Firebase database, there are many statuses I added and I retrieved successfully, but the problem is in other activity display only one selected status so in other Activity I put two buttons called forward and rewind. So when I click Forward button how can I get next status?
public class H_Status_Sub_Activity extends AppCompatActivity {
private static ArrayList<String> list;
private static ArrayAdapter<String> adapter;
public static DatabaseReference databaseReference;
private static TextView textView;
TextView txt_listview;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_h__status__sub_);
final Bundle bundle = getIntent().getExtras();
String main_cat = bundle.getString("name");
String sub_cat = bundle.getString("name1");
mlistView = (ListView) findViewById(R.id.h_s_s_listView);
txt_listview = (TextView) findViewById(R.id.txt_listview);
databaseReference = FirebaseDatabase.getInstance().getReference("Status").child(main_cat).child(sub_cat);
list = new ArrayList<>();
adapter = new ArrayAdapter<String>(this, R.layout.item_listview, R.id.txt_listview, list);
databaseReference.addChildEventListener(new ChildEventListener() {
#Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
ValueData = String.valueOf((dataSnapshot.getValue()));
list.add(ValueData);
mlistView.setAdapter(adapter);
progressDialog.dismiss();
}
#Override
public void onChildChanged(DataSnapshot dataSnapshot, String s) { adapter.notifyDataSetChanged(); }
#Override
public void onChildRemoved(DataSnapshot dataSnapshot) { adapter.notifyDataSetChanged(); }
#Override
public void onChildMoved(DataSnapshot dataSnapshot, String s) { adapter.notifyDataSetChanged(); }
#Override
public void onCancelled(DatabaseError databaseError) { adapter.notifyDataSetChanged(); }
});
}
public void Display_Txt(View view){
txt_listview=(TextView)view.findViewById(R.id.txt_listview);
Bundle bundle = new Bundle();
bundle.putString("Full Screen Text",txt_listview.getText().toString());
bundle.putString("list", String.valueOf(list));
Intent intent = new Intent(H_Status_Sub_Activity.this, Display_Full_Screen_Activity.class);
intent.putExtras(bundle);
startActivity(intent);
}
This is my other Activity In which I display particular text in full size, but In XML file there are two buttons called forward and rewind. When I click that button next status needs to appear, but I don't know how to do that.
public class Display_Full_Screen_Activity extends AppCompatActivity {
private TextView txt_display_status;
private Button
btn_zoomin,btn_zoomout,btn_copy,btn_share,btn_forward,btn_rewind;
private int x =20;
private static DatabaseReference databaseReference = H_Status_Main_Activity.databaseReference;
String Full_Screen_Text;
String Status_List;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display__full__screen_);
init();
Bundle bundle = getIntent().getExtras();
Full_Screen_Text = bundle.getString("Full Screen Text");
Status_List = bundle.getString("list");
txt_display_status.setText(Full_Screen_Text);
}
public void Forward(View view){
txt_display_status.setText(Status_List + 1);
}
public void Rewind(View view) {
}
public void Zoom_In(View view) {
txt_display_status.getTextSize();
txt_display_status.setTextSize((x++));
txt_display_status.setTextSize(x);
}
public void Zoom_Out(View view) {
txt_display_status.getTextSize();
txt_display_status.setTextSize(x--);
txt_display_status.setTextSize(x);
}
public void Copy(View view) {
ClipboardManager clipboardManager =(ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clipData = ClipData.newPlainText("Lable",txt_display_status.getText().toString());
clipboardManager.setPrimaryClip(clipData);
Toast.makeText(Display_Full_Screen_Activity.this, "Text Copied" , Toast.LENGTH_SHORT).show();
}
public void Share(View view) {
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(Intent.EXTRA_SUBJECT, "UNTOALD STORY");
String shareText = txt_display_status.getText().toString();
// shareText = shareText + "http://www.skynils.com/";
// if you have live app then you can share link like below
//shareText = shareText + "https://play.google.com/store/apps/details?id=" + context.getPackageName();
i.putExtra(Intent.EXTRA_TEXT, shareText);
startActivity(Intent.createChooser(i, "Share via"));
}
public void whatsapp(View view) {
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
// i.putExtra(Intent.EXTRA_SUBJECT, "UNTOALD STORY");
String shareText = txt_display_status.getText().toString();
// shareText = shareText + "http://www.skynils.com/";
i.putExtra(Intent.EXTRA_TEXT, shareText);
i.setPackage("com.whatsapp");
startActivity(Intent.createChooser(i, "Share via"));
}

Android Pass string to non Activity

I have MainActivity with two String variables viz. filename & url.
I tried to use one download manager.
I dont know how to pass filename String from my Player Activity.
buttondownload = (TextView )findViewById(R.id.download);
buttondownload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DownloadHelper.addNewTask(Player.this, url,
new PreDownloadStatusListener() {
#Override
public void notFoundSDCard(int errorCode, String errorInfo) {
Toast.makeText(Player.this, "No SD Card", Toast.LENGTH_SHORT).show();
}
#Override
public void sdCardCannotWriteOrRead(int errorCode, String errorInfo) {
Toast.makeText(Player.this, "Not read and write SD card", Toast.LENGTH_SHORT).show();
}
#Override
public void moreTaskCount(int errorCode, String errorInfo) {
Toast.makeText(Player.this, "Task list is full", Toast.LENGTH_SHORT).show();
}
});
Intent intent1 = new Intent(Player.this, DownloadListActivity.class);
startActivity(intent1);
}
});
DownloadHelper.startAllTask(Player.this);
mReceiver = new DownloadReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(DownloadValues.Actions.BROADCAST_RECEIVER_ACTION);
registerReceiver(mReceiver, filter);
They call filename from another public class DownloadUtils.. How can i pass filname to DownloadUtils
I want Pass String from Player to ViewHolder.java
package com.download.main;
public class ViewHolder {
public static final int KEY_URL = 0;
public static final int KEY_SPEED = 1;
public static final int KEY_PROGRESS = 2;
public static final int KEY_IS_PAUSED = 3;
public TextView titleText;
public ProgressBar progressBar;
public TextView speedText;
public ImageButton pauseButton;
public ImageButton deleteButton;
public ImageButton continueButton;
private boolean hasInited = false;
public ViewHolder(View parentView) {
if (parentView != null) {
titleText = (TextView) parentView.findViewById(R.id.title);
speedText = (TextView) parentView.findViewById(R.id.speed);
progressBar = (ProgressBar) parentView.findViewById(R.id.progress_bar);
pauseButton = (ImageButton) parentView.findViewById(R.id.btn_pause);
deleteButton = (ImageButton) parentView.findViewById(R.id.btn_delete);
continueButton = (ImageButton) parentView.findViewById(R.id.btn_continue);
hasInited = true;
}
}
public static HashMap<Integer, String> getItemDataMap(String url, String speed, String progress, String isPaused) {
HashMap<Integer, String> item = new HashMap<Integer, String>();
item.put(KEY_URL, url);
item.put(KEY_SPEED, speed);
item.put(KEY_PROGRESS, progress);
item.put(KEY_IS_PAUSED, isPaused);
return item;
}
public void setData(HashMap<Integer, String> item) {
if (hasInited) {
titleText.setText(///////**I want here my my string calle "filename" from player Activity**//////);
speedText.setText(item.get(KEY_SPEED));
String progress = item.get(KEY_PROGRESS);
if (TextUtils.isEmpty(progress)) {
progressBar.setProgress(0);
}
else {
progressBar.setProgress(Integer.parseInt(progress));
}
if (Boolean.parseBoolean(item.get(KEY_IS_PAUSED))) {
onPause();
}
}
}
public void onPause() {
if (hasInited) {
pauseButton.setVisibility(View.GONE);
continueButton.setVisibility(View.VISIBLE);
}
}
public void setData(String url, String speed, String progress) {
setData(url, speed, progress, false + "");
}
public void setData(String url, String speed, String progress, String isPaused) {
if (hasInited) {
HashMap<Integer, String> item = getItemDataMap(url, speed, progress, isPaused);
titleText.setText(///////**I want here my my string calle "filename" from player Activity**//////);
speedText.setText(speed);
if (TextUtils.isEmpty(progress)) {
progressBar.setProgress(0);
}
else {
progressBar.setProgress(Integer.parseInt(item.get(KEY_PROGRESS)));
}
}
}
}

To pass any data from one activity to another use Intent. Example:-
Use below code in your Player.java class:-
Intent intent = new Intent(FromClass.this, ToClass.class);
intent.putExtra("filename", filename);
startActivity(intent);
Write the below code in the ViewHolder.java class:-
do not forget to extend Activity
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.yourLayoutName);
Intent intent = getIntent();
String filename= intent.getStringExtra("filename");
}
Then you can use filename in your setData() like this:-
public void setData(HashMap<Integer, String> item) {
if (hasInited) {
titleText.setText(filename);
speedText.setText(item.get(KEY_SPEED));
String progress = item.get(KEY_PROGRESS);
if (TextUtils.isEmpty(progress)) {
progressBar.setProgress(0);
}
else {
progressBar.setProgress(Integer.parseInt(progress));
}
if (Boolean.parseBoolean(item.get(KEY_IS_PAUSED))) {
onPause();
}
}
}
