I want to reload the WebView every some seconds using timer or delay method
or even delay within a loop
this is my code
private WebView mWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
Timer repeatTask = new Timer();
repeatTask.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
runOnUiThread(new Runnable() {
#Override
public void run() {
webview.loadUrl("yoururl");
}
});
}
}, 0, 5000);

Hello I would like to show my ZXingScanner in afragment
I've try this :
scannerView.setResultHandler(getActivity()); and
scannerView.resumeCameraPreview(getActivity());
This is my fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.fragment_scan_qr, container, false);
qrCameraLayout = (LinearLayout) mView.findViewById(R.id.layoutScanner);
scannerView = new ZXingScannerView(getActivity().getApplicationContext());
scannerView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));
qrCameraLayout.addView(scannerView);
return mView;
}
#Override
public void onResume() {
super.onResume();
if (scannerView == null){
scannerView = new ZXingScannerView(getActivity().getApplicationContext());
qrCameraLayout.addView(scannerView);
}
scannerView.setResultHandler(getActivity());
scannerView.startCamera();
}
#Override
public void onDestroy() {
super.onDestroy();
scannerView.stopCamera();
}
#Override
public void onPause() {
super.onPause();
scannerView.stopCamera();
}
public void handleResult(Result result) {
String scanResult = result.getText();
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity().getApplicationContext());
builder.setTitle("Scan Result");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
scannerView.resumeCameraPreview(getActivity().getApplicationContext());
}
});
builder.setNegativeButton("Cancel",null);
builder.setMessage(scanResult);
AlertDialog alertDialog = builder.create();
alertDialog.show();
}
You don't need setContentView for fragment, it is required only for
activity.And you are getting inflated view as below:
View mView = inflater.inflate(R.layout.fragment_scan_qr, container, false);
appreciate if you can help me here.
I am creating a To Do List, where the ListView is in the MainToDoList Activity with a "Add a new Task" button that takes the user to the second activity.
In the second activity, there is a Edit Text field where user can input the title of the task. Two buttons are "Save" and "Cancel"
My question is, how to pass the edit text value after pressing the save button to display it into the listview in the first activity.
First Activity:
public class Todolistactivity extends AppCompatActivity {
private Button btn;
private ListView list;
private DrawerLayout drawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.todolistactivity);
btn = findViewById(R.id.addTask);
list = findViewById(R.id.task_list);
}
private void addTask() {
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(Todolistactivity.this, EditToDo.class));
}
});
}
Second Activity:
public class EditToDo extends Todolistactivity {
private static final String TAG = "EditToDo";
private Button save;
private Button cancel;
private EditText title;
#Override
protected void onCreate (Bundle savedInstance){
super.onCreate(savedInstance);
setContentView(R.layout.activity_taskedit);
save = findViewById(R.id.saveTask);
cancel = findViewById(R.id.cancelTask);
title = findViewById(R.id.taskTitle);
saveButton();
cancelButton();
}
private void saveButton(){
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent backToDo = new Intent
(getBaseContext(),Todolistactivity.class);
String titleEntered = title.getText().toString();
backToDo.putExtra("task", titleEntered);
startActivity(backToDo);
}
});
}
Use startActivityForResult
in your Todolistactivity class
private void addTask() {
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivityForResult(new Intent(Todolistactivity.this, EditToDo.class), 100); // 100 is request code.
}
});
}
//...
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 100) {
if(resultCode == Activity.RESULT_OK){
String result = data.getStringExtra("task");
}
else if (resultCode == Activity.RESULT_CANCELED) {
//...
}
}
}
In Your EditToDo class
private void saveButton(){
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String titleEntered = title.getText().toString();
Intent intent = new Intent();
intent.putExtra("task", titleEntered);
setResult(Activity.RESULT_OK, intent);
finish();
}
});
}
I`v been trying for a while to destroy activity when the home button is pressed or when the app is in background and I manage to do something with this code
#Override
protected void onPause() {
this.finish();
super.onPause();
}
and when the app runs it does not crash but after a while playing in the activity the app just goes background and crashes.
This is the activity that I`m talking about:
public class Playing extends AppCompatActivity implements View.OnClickListener {
final static long INTERVAL=1154;//1 second
final static long TIMEOUT=7000;
int progressValue = 0;
CountDownTimer mcountDown;
List<Question> questionPlay = new ArrayList<>();
DbHelper db;
int index=0 , score =0,thisQuestion=0,totalQuestion,CorrectAnswer;
String mode = "";
ProgressBar progressBar;
ImageView imageView;
Button btnA, btnB, btnC,btnD;
TextView txtScore,txtQuestion;
#Override
protected void onPause() {
this.finish();
super.onPause();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_playing);
Bundle extra = getIntent().getExtras();
if(extra!=null)
mode =extra.getString("MODE");
db = new DbHelper(this);
txtScore = (TextView)findViewById(R.id.txtScore);
txtQuestion =(TextView)findViewById(R.id.txtQuestion);
progressBar=(ProgressBar) findViewById(R.id.progreessBar);
btnA = (Button) findViewById(R.id.btnAnswerA);
btnB =(Button)findViewById(R.id.btnAnswerB);
btnC = (Button)findViewById(R.id.btnAnswerC);
btnD = (Button)findViewById(R.id.btnAnswerD);
imageView = (ImageView)findViewById(R.id.question_bike);
btnA.setOnClickListener(this);
btnB.setOnClickListener(this);
btnC.setOnClickListener(this);
btnD.setOnClickListener(this);
}
#Override
protected void onResume() {
super.onResume();
questionPlay = db.getQuestionMode(mode);
totalQuestion = questionPlay.size();
mcountDown = new CountDownTimer(TIMEOUT, INTERVAL) {
#Override
public void onTick(long millisUntilFinished) {
progressBar.setProgress(progressValue);
progressValue++;
}
#Override
public void onFinish() {
mcountDown.cancel();
showQuestion(++index);
}
};
showQuestion(index);
}
private void showQuestion(int index) {
if (index < totalQuestion){
thisQuestion++;
txtQuestion.setText(String.format("%d %d",thisQuestion,totalQuestion));
progressBar.setProgress(0);
progressValue = 0;
int ImageID = this.getResources().getIdentifier(questionPlay.get(index).getImage().toLowerCase(),"drawable",getPackageName());
imageView.setBackgroundResource(ImageID);
btnA.setText(questionPlay.get(index).getAnswerA());
btnB.setText(questionPlay.get(index).getAnswerB());
btnC.setText(questionPlay.get(index).getAnswerC());
btnD.setText(questionPlay.get(index).getAnswerD());
mcountDown.start();
}
else {
Intent intent = new Intent(this,Done.class);
Bundle dataSend = new Bundle();
dataSend.putInt("SCORE", score);
dataSend.putInt("TOTAL",totalQuestion);
dataSend.putInt("CORRECT",CorrectAnswer);
intent.putExtras(dataSend);
startActivity(intent);
finish();
}
}
#Override
public void onClick(View v) {
mcountDown.cancel();
if (index < totalQuestion){
Button clickedButton = (Button)v;
if(clickedButton.getText().equals(questionPlay.get(index).getCorrectAnswer())){
score+=1;
CorrectAnswer++;
showQuestion(++index);
}
else showQuestion(++index);
txtScore.setText(String.format("S:%d",score));
}
}
#Override
public void onBackPressed() {
Intent intent = new Intent(Playing.this ,MainActivity.class) ;
startActivity(intent) ;
finish() ;
}
}
I`v tried and with this code
#Override
protected void onDestroy(){
super.onDestroy;
finish();
}
but then the second activity does not start and the app crashes again.
So what to do?

I am developing a simple app in that my video is playing proper. but now I want to give "thank" message after finishing my video
How can I do this?
MainActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
this.setSupportActionBar(toolbar);
final MediaPlayer player = MediaPlayer.create(MainActivity.this,R.raw.video);
Button button = (Button)findViewById(R.id.video_Play);
button.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
player.start();
startActivity(new Intent("com.example.lenovo.play.app.VideoPlay"));
}
});
}
and Second VideoPlay.java
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.video_layout);
view = (VideoView)findViewById(R.id.videoView);
String url = "android.resource://"+getPackageName()+"/"+R.raw.video;
view.setVideoURI(Uri.parse(url));
view.start();
int duration = view.getDuration();
}
Implement MediaPlayer.OnCompletionListener then add your message to onCompletion method:
#Override
public void onCompletion(MediaPlayer mp) {
//message
}
