I'm trying to do a intro tutorial for my android aplication that uses View Pager with Fragments Pager Adapter and the things don't work with fragments.
I'm using this library: https://github.com/amlcurran/ShowcaseView
t1 = new ViewTarget(R.id.btnGenerate, getActivity());
t2 = new ViewTarget(R.id.cbFavorito, getActivity());
t3 = new ViewTarget(R.id.txtResult, getActivity());
view.post(new Runnable() {
#Override
public void run() {
if(isAdded()) {
showcaseView = new ShowcaseView.Builder(getActivity())
.setTarget(Target.NONE)
.setContentTitle("Tutorial")
.setContentText("Aprenda como usar o aplicativo")
.build();
showcaseView.setButtonText("Next");
showcaseView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
switch (contador) {
case 0:
showcaseView.setShowcase(t1, true);
showcaseView.setContentTitle("Teste");
showcaseView.setContentText("Teste");
break;
case 1:
showcaseView.setShowcase(t2, true);
showcaseView.setContentTitle("Gerar um nome");
showcaseView.setContentText("Teste");
break;
case 2:
showcaseView.setShowcase(t3, true);
showcaseView.setContentTitle("Adicionar aos Favoritos");
showcaseView.setContentText("teste");
showcaseView.setButtonText("Fechar");
break;
case 3:
showcaseView.hide();
break;
}
contador++;
}
});
}
}
});
In the code above I'm trying to focus different buttons when I click in button Next of ShowCase View, but, when is clicked the tutorial just closes, nothing happens, no erros, just closes.
You dont have take the event Listner from Button, try this:
public void run() {
try {
showCase();
} catch (Exception e) {
e.printStackTrace();
}
and ShowCase:
showcaseView = new ShowcaseView.Builder(getActivity())
.setTarget(new ViewTarget(R.id.tool_bar, getActivity()))
.setContentTitle(getString(R.string.title_list_os))
.setContentText(getString(R.string.dica_atualizar_os))
.setOnClickListener(this)
.setStyle(R.style.CustomShowcaseTheme)
.build();
your activity needs Implements View.OnclickListener
Sorry my english.

HELP ME PLEASE! I want to create 2 buttons ("Next" and "Previous") that will change the text in TextView. I made a switch and "systemcounter" to change the cases, which then will set another text in TextView. When I test my program in this window buttons do not change the pages. I think this is because the system cannot see the "systemcounter"
private Button next_button;
private Button previous_button;
private TextView Text_set1;
int systemcounter = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_learningpage);
next_button = (Button) findViewById(R.id.next_button);
previous_button = (Button) findViewById(R.id.previous_button);
Text_set1 = (TextView) findViewById(R.id.Text_set);
next_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
systemcounter = systemcounter + 1;
}
});
previous_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
systemcounter = systemcounter - 1;
}
});
switch (systemcounter) {
case (0):
Text_set1.setText("Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.");
previous_button.setVisibility(View.INVISIBLE);
break;
case (1):
Text_set1.setText("Hi there");
previous_button.setVisibility(View.VISIBLE);
break;
case (2):
Text_set1.setText("How are you");
previous_button.setVisibility(View.VISIBLE);
break;
case (3):
Text_set1.setText("How old are you?");
break;
default:
Text_set1.setText("OPS");
break;
}```
you have switch statement in oncreate method and so it executes it only once, make a seperate method like
setEditText(int systemcount) and create your switch tehre and call this methods from button onclick methods
private void setText() {
switch (systemcounter) {
case (0):
Text_set1.setText("Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.");
previous_button.setVisibility(View.INVISIBLE);
break;
case (1):
Text_set1.setText("Hi there");
previous_button.setVisibility(View.VISIBLE);
break;
case (2):
Text_set1.setText("How are you");
previous_button.setVisibility(View.VISIBLE);
break;
case (3):
Text_set1.setText("How old are you?");
break;
default:
Text_set1.setText("OPS");
break;
}
}
and call this method in your listeners (like this)
next_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
systemcounter = systemcounter + 1;
setText();
}
});
As I mentioned in the title ,I want to add text to a Textview without replacing the previous text .
In my application I have a TextView and 7 buttons .On every button click I set the text of button to the TextView.
If the button is clicked on first time ,Setting the text to TextView ,and if the same button is clicked 2nd time I am removing that button's text from TextView.
Here What I want to do is for 7 buttons I want to set positions(uniqueness for sun to sat) in TextView and when the respective button is clicked that text is set to the TextView and if the button is clicked 2nd time that specific position of the text should remove .
Here text shouldn't replace the previous text that is important to have and if some button's are selected and again that are deselected means TextView should show the default text as "Never"
I tried to get source from SO but I can't find a clear solution for this .
If anyone helps me to come out from this ,that's much helpful for me .
coding
public class CreateAlarm extends Activity implements View.OnClickListener {
private Button mbtn_Sun, mbtn_Mon, mbtn_Tue, mbtn_Wed, mbtn_Thu, mbtn_Fri, mbtn_Sat;

Image :
By default the TextView text is "Never".
You can define a TreeMap as:
private TreeMap<Integer, String> mAlarmDays = new TreeMap<>();
as a field of your class and add/remove the days to/from the TreeMap when the corresponding button is clicked. So the implementation of onClick method will be:
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.mbtn_Sun:
if (mRepeat.getText().toString().contains("Sun")) {
mAlarmDays.remove(0);
} else
mAlarmDays.put(0, "Sun");
break;
case R.id.mbtn_Mon:
if (mRepeat.getText().toString().contains("Mon")) {
mAlarmDays.remove(1);
} else
mAlarmDays.put(1, "Mon");
break;
case R.id.mbtn_Tue:
if (mRepeat.getText().toString().contains("Tue")) {
mAlarmDays.remove(2);
} else
mAlarmDays.put(2, "Tue");
break;
case R.id.mbtn_Wed:
if (mRepeat.getText().toString().contains("Wed")) {
mAlarmDays.remove(3);
} else
mAlarmDays.put(3, "Wed");
break;
case R.id.mbtn_Thu:
if (mRepeat.getText().toString().contains("Thu")) {
mAlarmDays.remove(4);
} else
mAlarmDays.put(4, "Thu");
break;
case R.id.mbtn_Fri:
if (mRepeat.getText().toString().contains("Fri")) {
mAlarmDays.remove(5);
} else
mAlarmDays.put(5, "Fri");
break;
case R.id.mbtn_Sat:
if (mRepeat.getText().toString().contains("Sat")) {
mAlarmDays.remove(6);
} else
mAlarmDays.put(6, "Sat");
break;
}
StringBuilder repeatDays = new StringBuilder();
if (mAlarmDays.size() == 0) {
repeatDays = new StringBuilder("Never");
} else {
for (String day:mAlarmDays.values()) {
repeatDays.append(day).append(" ");
}
}
mRepeat.setText(repeatDays.toString());
}
You should set each button id first,add this to your xml for each specific button : android:id="sun" and ...
My suggestion is: use a single TextView can make your logic quite complex
Use a horizontal LinearLayout instead, you will have 7 TextView inside with predefine text and position. Just simply show/hide them according to which button is clicked and you don't have to deal with any complex string analize.
I want to use viewpager inside recycler view and set data on pager from api.
For more details, i'm adding my code in question.
My Code is
public void onBindViewHolder(final worksheetAdapter.CustomViewHolder holder, final int position) {
final int a = position; rec_worksheet.setTag(position);
Set text on TextView
holder.question.setText(userlist.get(position).get("ques"));
holder.question.startAnimation(animFadein);
holder.tvans1.setText(userlist.get(position).get("ans1"));
holder.tvans1.startAnimation(animFadein);
holder.tvans2.setText(userlist.get(position).get("ans2"));
holder.tvans2.startAnimation(animFadein);
holder.tvans3.setText(userlist.get(position).get("ans3"));
holder.tvans3.startAnimation(animFadein);
holder.tvans4.setText(userlist.get(position).get("ans4"));
holder.tvans4.startAnimation(animFadein);
holder.submitbtn.setVisibility(View.GONE);
if(position == userlist.size() - 1){
holder.submitbtn.setVisibility(View.VISIBLE);
}
holder.queNo.setText("Question No "+String.valueOf(position+1));
holder.tvTotalQue.setText("Total Ques. "+String.valueOf(userlist.size()));
holder.tvSubName.setText(userlist.get(position).get("subject_name"));
holder.submitbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
submit();

You cannot use a viewpager inside a recyclerview. If you want to use horizontal swiping inside a recyclerview then you will have to use a recyclerview inside a recyclerview. This child recyclerview will be have a horizontal layout.
This question precisely addresses that.
For the 2nd issue:
Add the following lines
holder.llAns2.setBackgroundResource(R.drawable.round_strock_green);
holder.llAns1.setBackgroundResource(R.drawable.round_strock_green);
holder.llAns3.setBackgroundResource(R.drawable.round_strock_green);
holder.llAns4.setBackgroundResource(R.drawable.round_strock_green);
below this line:
if(position == userlist.size() - 1){
holder.submitbtn.setVisibility(View.VISIBLE);
}
for 3rd issue:
//add this below your adapter class
private ArrayList selectedOptions;
in your onbindviewholder add this below holder.llAns4.setBackgroundResource(R.drawable.round_strock_green)
if(selectedOptions.get(position) != null){
switch (selectedOptions.get(position)){
case 1:
holder.llAns1.setBackgroundResource(R.drawable.que_correct_back);
break;
case 2:
holder.llAns2.setBackgroundResource(R.drawable.que_correct_back);
break;
case 3:
holder.llAns3.setBackgroundResource(R.drawable.que_correct_back);
break;
case 4:
holder.llAns4.setBackgroundResource(R.drawable.que_correct_back);
break;
}
}
I have answered 3 things now. Please ask new stackoverflow question for further issues.
I know this has been asked a million times but none have led me to solving my problem. The onclicklistener will not activate the code for any of the buttons. Here are the different sections that apply to the five buttons.
Button btnGuysMax;
Button btnGuysMedium;
Button btnEven;
Button btnGirlsMedium;
Button btnGirlsMax;
....
private void init()
{
datasource = new BarsDataSource(this);
datasource.open();
Intent intent = getIntent();
long id = intent.getLongExtra("bar_id",0);
bar = datasource.getBarById(id);
title = (TextView)findViewById(R.id.title);
btnGuysMax = (Button)findViewById(R.id.btnGuysMax);
btnGuysMedium = (Button)findViewById(R.id.btnGuysMedium);
btnEven = (Button)findViewById(R.id.btnEven);
btnGirlsMedium = (Button)findViewById(R.id.btnGirlsMedium);
btnGirlsMax = (Button)findViewById(R.id.btnGirlsMax);
......
btnGuysMax.setOnClickListener(this);
btnGuysMedium.setOnClickListener(this);
btnEven.setOnClickListener(this);
btnGirlsMedium.setOnClickListener(this);
btnGirlsMax.setOnClickListener(this);
.....
#Override
public void onClick(View view)
{
//resetButtons();
switch (view.getId()) {
case R.id.btnGuysMax:
//bar.setSexRatio(-2);
//btnGuysMax.setBackgroundColor(guysMaxColor);
Toast.makeText(this,"Max clicked!",Toast.LENGTH_LONG);
break;
case R.id.btnGuysMedium:
bar.setSexRatio(-1);
Toast.makeText(this,"Medium clicked!",Toast.LENGTH_LONG);
//btnGuysMedium.setBackgroundColor(guysMediumColor);
break;
case R.id.btnEven:
bar.setSexRatio(0);
//Toast.makeText(this,"Medium clicked!",Toast.LENGTH_LONG);
break;
case R.id.btnGirlsMedium:
bar.setSexRatio(1);
//btnGirlsMedium.setBackgroundColor(girlsMediumColor);
break;
case R.id.btnGirlsMax:
bar.setSexRatio(2);
break;
.....
To display a toast you need to call show method.
Try:
Toast.makeText(this,"message",Toast.LENGTH_LONG).show();
try doing:
#Override
public void onClickListener(View view)
{
instead of:
#Override
public void onClick(View view)
{
I want the dialog to show the correct text based on the selected option (ie. If pressed TWO I want is to show the text "you pressed TWO")
on the first press it seemingly does nothing the text goes to the initialized
on the second press you find out the text was switched to default
I'm new to android and I don't think I understand what the activity is doing here.
Can someone please help me find a way that works?
public class AndMainT extends Activity {
private GameLogicT myGame = new GameLogicT();
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b_com = (Button)findViewById(R.id.button);
b_com.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
CharSequence[] pick_one = {"ONE", "TWO", "THREE"};
call_menu(pick_one);
updateAwesomeText();
}
});
}
public void updateAwesomeText(){
TextView newText = (TextView)findViewById(R.id.text);
newText.setText(myGame.getCurrent_opt().getDescription() + "\n");
}
public void call_menu(CharSequence[] items){
final CharSequence[] f_items = items;
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Orders Captain?");
builder.setItems(f_items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
myGame.startOpt(item);
}
});
builder.show();
}
}
public class GameLogicT {
class GOpt{
private CharSequence description = "this is the intialized text sadface";
public CharSequence getDescription() {
return description;
}
public void setDescription(CharSequence description) {
this.description = description;
}
}
private GOpt current_opt = new GOpt();
public void startOpt(int item){
switch(item){
case 1:
current_opt.setDescription("you pressed ONE");
case 2:
current_opt.setDescription("you pressed TWO");
case 3:
current_opt.setDescription("you pressed THREE");
default:
current_opt.setDescription("I am a fart and think you have pressed nothing sadface");
}
}
public GOpt getCurrent_opt() {
return current_opt;
}
public void setCurrent_opt(GOpt current_opt) {
this.current_opt = current_opt;
}
}
I also tried
public void onClick(View v) {
CharSequence[] pick_one = {"ONE", "TWO", "THREE"};
call_menu(pick_one);
try {
wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
updateAwesomeText();
}
public void onClick(DialogInterface dialog, int item) {
myGame.startOpt(item);
notify();
}
This causes a force close when the button is pressed, it's not my question just saying I tried!
sorry but I can't test your code due a lot of work.
However,after taking a look I noticed the following:
1) I think that position of items starts from index 0.
2) Maybe you lost some break in the switch-casestatement
So, try to replace it with:
public void startOpt(int item){
switch(item){
case 0:
current_opt.setDescription("you pressed ONE");
break;
case 1:
current_opt.setDescription("you pressed TWO");
break;
case 2:
current_opt.setDescription("you pressed THREE");
break;
default:
current_opt.setDescription("I am a fart and think you have pressed nothing sadface");
}
}
Hope it helps you!
