I have a popup text view with a next button and onClick I would like to switch the content.
This is what I tried ...cant get it to work. The error im getting is type mismatch cannot convert from void to int

Yeah, lack of research. Didn't know about string arrays...finally got it!

myString = res.getStringArray(R.array.lessons_dialog_array);
Button nextButton = (Button) findViewById(R.id.next_button);
nextButton.setOnClickListener(new View.OnClickListener() {

lessonsDialog.setText(lessonDialogString[count]);
count++;
}
}
});
}
}
There are a few problems here.
I don't know what you are trying to do here:
nextSwitch = (TextView) findViewById(R.id.lessonsDialog);
tutStrings = nextSwitch.setText(R.string.lessons_introduction); //type mismatch cannot convert from void to int
tutStrings2 = nextSwitch.setText(R.string.lessons_introduction2); //type mismatch cannot convert from void to int
tutStrings3 = nextSwitch.setText(R.string.lessons_introduction3); //type mismatch cannot convert from void to int
the TextView.setText(String) does not return a value so these lines don't make any sense. Are you trying to save the strings themselves?
Also your onClick method has problems as well. The View that is passed to onClick is the actual view that was clicked which in this case will be the nextButton. In your code you are switching on the undefined ints and not the id's of the different views in your activity.
Instead do something like this:
void onClick(View v){
switch(v.getId()){
case R.id.next_button:
setTextViewNextString();
break;
case R.id.prev_button:
setTextViewPrevString();
}
Then you simply define the setTextViewNextString() and setTextViewPrevString() methods
The method setText returns void:
public final void setText (int resid)
(from http://developer.android.com/reference/android/widget/TextView.html#setText%28int%29)
You cannot assign void to int variables. These lines
tutStrings = nextSwitch.setText(R.string.lessons_introduction); //type mismatch cannot convert from void to int
tutStrings2 = nextSwitch.setText(R.string.lessons_introduction2); //type mismatch cannot convert from void to int
tutStrings3 = nextSwitch.setText(R.string.lessons_introduction3); //type mismatch cannot convert from void to int
are wrong.
I think you can solve your problem in this way:
1) Save the IDs in your private variables:
tutStrings = R.string.lessons_introduction;
tutStrings2 = R.string.lessons_introduction2;
tutStrings3 = R.string.lessons_introduction3;
2) Save the strings, getting them from resources:
private String s1, s2, s3;
...
s1 = this.getString(R.string.lessons_introduction);
s2 = this.getString(R.string.lessons_introduction2);
s3 = this.getString(R.string.lessons_introduction3);
3) Now you can use the onClick method:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case tutStrings:
nextSwitch.setText(s2);
break;
case tutStrings2:
nextSwitch.setText(s3);
break;
}
}
Sorry, lack of research on my part. Used string-array.. works perfectly!
Change your Code like this:
tutStrings = this.getString(R.string.lessons_introduction);
tutStrings2 = this.getString(R.string.lessons_introduction2);
tutStrings3 = this.getString(R.string.lessons_introduction3);
Please Note: In onClick you have to replace this with the name of your class e.g. Myclass.getString or just remove the this.

I am new to android development and I am trying to pass a Boolean value from dialog fragment to the activity.
the boolean value is supposed to be decided by the user(depends on which button user clicked). However, the boolean immediately turned to false without clicking any button.
I have tried various method recommended I found on internet but none of them works for me(I guess I have some part screwed up...), these method include:
-broadcasting
-implementing interface
-intent.putExtra
and below is the code that I have came up with, could anyone help me take a look? Any help is appreciated.
Stage:
package com.example.fuj.valorsafeworldbytrade;
import android.support.v4.app.FragmentManager;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
import static com.example.fuj.valorsafeworldbytrade.LosingDialogFragment.LOSING_FRAGMENT;
public class Stage extends AppCompatActivity {
String stage;
FragmentManager fragmentManager = getSupportFragmentManager();
LosingDialogFragment losingDialogFragment = new LosingDialogFragment();
BasicInfo basicInfo = new BasicInfo();
public void setText(){
TextView cpuReputation = (TextView) findViewById(R.id.cpu_reputation);
TextView cpuGold = (TextView) findViewById(R.id.cpu_gold);
TextView pGoldText = (TextView) findViewById(R.id.player_gold);
TextView pRepText = (TextView) findViewById(R.id.player_reputation);
cpuReputation.setText(String.valueOf(basicInfo.cRep));
cpuGold.setText(String.valueOf(basicInfo.cGold));
pGoldText.setText(String.valueOf(basicInfo.pGold));
pRepText.setText(String.valueOf(basicInfo.pRep));
}
#Override

switch (view.getId()) {
case R.id.cooperate_button:

break;
case R.id.deceive_button:
deceiveEnabled = true;
break;

throw new RuntimeException("Unknown Button ID");
}
switch (stage){
case "xumo":
xuMo(deceiveEnabled);
break;
}
}
public void xuMo(boolean playerDeceiveEnabled){
boolean cpuDeceiveEnabled;
cpuDeceiveEnabled = (Math.random() - basicInfo.faith > 0);
if (cpuDeceiveEnabled){
if (playerDeceiveEnabled){
basicInfo.playerDvsCpuD();
// faith changes to be amend w/ proper value, need record on the change of status
}
if (!playerDeceiveEnabled){
basicInfo.playerCvsCpuD();
}
}
if (!cpuDeceiveEnabled){

basicInfo.playerDvsCpuC();
}
if (!playerDeceiveEnabled){
basicInfo.playerCvsCpuC();
}
}

losingDialogFragment.show(fragmentManager,LOSING_FRAGMENT);
//trying to show a alert dialog fragment
Log.d("True", String.valueOf(losingDialogFragment.tryAgainEnabled));
if(losingDialogFragment.tryAgainEnabled){//tryAgainEnabled is always false
//This is the part that I wanted to retrieve data from the user(if they want to try again or not)
basicInfo.reset();
losingDialogFragment.dismiss();
}else{
losingDialogFragment.dismiss();
}
}
setText();
// to be changed
}
}
LosingDialogFragment:
package com.example.fuj.valorsafeworldbytrade;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
/**
* Created by fuj on 20/1/2017.
*/
public class LosingDialogFragment extends DialogFragment{
public static final String LOSING_FRAGMENT = "LOSING";
public boolean tryAgainEnabled;
Intent intent = new Intent();
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.fragment_lose, container, false);;
//the following code is used to set the boolean value after the user click the button
final Button tryAgainButton = (Button)rootView.findViewById(R.id.try_again_button);
tryAgainButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tryAgainEnabled = true;
}
});
Button giveUpButton =(Button)rootView.findViewById(R.id.give_up_button);
giveUpButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tryAgainEnabled = false;
}
});
getDialog().setTitle(LOSING_FRAGMENT);
return rootView;
}
}
I am also sorry that I am not the best with English, if any things is not clear or not polite because of my poor English, please kindly let me know. I apologize in advance for any mistakes I have made.
It's because you check the value of tryAgainEnabled exactly right after showing the Dialog. Dialog starts Asynchronously, It means that it starts in diffrent Thread and your current thread doesn't wait for dismissing Dialog, So this line of your code if(losingDialogFragment.tryAgainEnabled){ runs exactly after you show dialog, befor you set value to tryAgainEnabled. Because the default value of boolean is always false, you will get false everytime.
I suggest that use listener for this:
Dialog:
public class LosingDialogFragment extends DialogFragment {
public static final String LOSING_FRAGMENT = "LOSING";
public boolean tryAgainEnabled;
Intent intent = new Intent();
private View.OnClickListener onTryAgainButtonClickLisnter;
private View.OnClickListener onGiveUpButtonClickLisnter;
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.fragment_lose, container, false);;
final Button tryAgainButton = (Button)rootView.findViewById(R.id.try_again_button);
tryAgainButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(onTryAgainButtonClickLisnter!=null)
onTryAgainButtonClickLisnter.onClick(v);
}
});
Button giveUpButton =(Button)rootView.findViewById(R.id.give_up_button);
giveUpButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(onGiveUpButtonClickLisnter!=null)
onGiveUpButtonClickLisnter.onClick(v);
}
});
getDialog().setTitle(LOSING_FRAGMENT);
return rootView;
}
public void setOnTryAgainButtonClickLisnter(View.OnClickListener onTryAgainButtonClickLisnter) {
this.onTryAgainButtonClickLisnter = onTryAgainButtonClickLisnter;
}
public void setOnGiveUpButtonClickLisnter(View.OnClickListener onGiveUpButtonClickLisnter) {
this.onGiveUpButtonClickLisnter = onGiveUpButtonClickLisnter;
}
}
In your activity call dialog like this:
LosingDialogFragment losingDialogFragment = new LosingDialogFragment();
losingDialogFragment.setOnTryAgainButtonClickLisnter(new View.OnClickListener() {
#Override
public void onClick(View v) {
tryAgain();
losingDialogFragment.dismiss();
}
});
losingDialogFragment.setOnGiveUpButtonClickLisnter(new View.OnClickListener() {
#Override
public void onClick(View v) {
giveUp();
losingDialogFragment.dismiss();
}
});
losingDialogFragment.show(fragmentManager, "");
Declare public boolean tryAgainEnabled; in your Stage Activity and youd can update that variable using ((Stage)context).tryAgainEnabled.

How can I add time control. Thanks.
This bit of code doesn't look right
if(value == a) {
checkTrue();
} else {
finishScreen();
}
You should be using equals() to check for String equality. At the moment you are checking only object equality, which will evaluate to False, and the code will never call checkTrue().
Do this instead:
if(value.equals(a) {
checkTrue();
} else {
finishScreen();
}
I´ve succesfully implemented the RangeSeekbar from this website ( http://code.google.com/p/range-seek-bar/) into my App.
The Problem alot of people now have tho, is that we can´t find an onProgressChanged Method for the two thumbs in the code for the RangeSeekbar.
Do i have to write my own onProgressChanged?
I implemented the RangeSeekbar into a DialogFragment. For the normal Seekbar everything worked fine.
http://www.directupload.net/file/d/3582/mokh6mkb_jpg.htm <-- How can I get the two TextViews to the left and right of "to" to show the selected Value of the RangeSeekbar?

Thank you for your help.
RangeSeekbar is a generic class. if your pass T parameter to it as type of range values, then RangSeekBar pass left thumb Value as minValue and right thumb Value as maxValue in
RangeSeekBar.OnRangeSeekBarChangeListener.(RangeSeekBar bar, T minValue, T maxValue).
change line of your class extends to:
public class LookingAgeFragment extends DialogFragment implements OnRangeSeekBarChangeListener<Integer>
after that you should change Object to Integer in your code at this line
seekBar.setOnRangeSeekBarChangeListener(new RangeSeekBar.OnRangeSeekBarChangeListener<Integer>() {
#Override
public void onRangeSeekBarValuesChanged(RangeSeekBar<?> bar, Integer minValue, Integer maxValue) {
viewMinAge.setText(String.valueOf(minValue));
viewMaxAge.setText(String.valueOf(minValue));
}
});
I think by this changes your problem will be solved.
for more generic solution when your ages range is not continuous and maybe discrete, I suggest this solution
public class LookingAgeFragment extends DialogFragment implements RangeSeekBar.OnRangeSeekBarChangeListener<Integer> {
RangeSeekBar<Integer> seekBar;
int[] ageValues={10, 20, 30, 50, 100};
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
// create RangeSeekBar as Integer range between 20 and 75
seekBar = new RangeSeekBar<Integer>(0, ageValues.length - 1, getActivity());
seekBar.setOnRangeSeekBarChangeListener(new RangeSeekBar.OnRangeSeekBarChangeListener<Integer>() {
#Override
public void onRangeSeekBarValuesChanged(RangeSeekBar<?> bar, Integer minValue, Integer maxValue) {
viewMinAge.setText(String.valueOf(ageValues[minValue]));
viewMaxAge.setText(String.valueOf(ageValues[minValue]));
}
});
}
}
I use next code for getting the values on changing event:
rangeSeekBar.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
Log.d("MinValue", rangeSeekBar.getSelectedMinValue().toString());
Log.d("MaxValue", rangeSeekBar.getSelectedMaxValue().toString());
return false;
}
});
In class ReangeSekkBar you have this if in ACTION_MOVE
if (notifyWhileDragging && listener != null) {
listener.onRangeSeekBarValuesChanged(this, getSelectedMinValue(), getSelectedMaxValue());
}
delete this if
//if (notifyWhileDragging && listener != null) {
listener.onRangeSeekBarValuesChanged(this, getSelectedMinValue(), getSelectedMaxValue());
//}
I want to make a simple calculator My code is below:
package som.dev.android.calc;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class CalcApp extends Activity {
/** Called when the activity is first created. */
Button addValues, subValues, equalsValue;
EditText inputValue;
int inputNum = 0;
public int value1;
public int value2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// initializing Views
inputValue = (EditText) findViewById(R.id.editText1);
addValues = (Button) findViewById(R.id.addBtn);
subValues = (Button) findViewById(R.id.subBtn);
equalsValue = (Button) findViewById(R.id.equalsBtn);
// adding onClick Listeners
addValues.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
pressed = true;
value1 = Integer.parseInt(inputValue.getText().toString());
inputValue.setText("");
}
});
equalsValue.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
value2 = Integer.parseInt(inputValue.getText().toString());
int result = value1+value2;
inputValue.setText(result);// There an exception occurs....
}
});
}
}
But it does not sets result to Edittext in my app and an exception occurs and message comes Unfortunately app is colsed some thing like that so please any one tell me the solution of this problem
use this inputValue.setText(""+result);instead of inputValue.setText(result);// There an exception occurs....
just conversion integer into string
The reason you get an exception is that the EditText thinks you are setting a resource id. You need to convert the integer to a string yourself Integer.toString(result) before using it in the EditText Object. http://developer.android.com/reference/android/widget/TextView.html
change Following Line:-
inputValue.setText(result);
to
inputValue.setText(String.Valueof(result));
then your error is solved.
on the press of my "next" button I have a speech bubble run through a string array. After all the items finish displaying and the user clicks the "next" button once more I would like to deflate the current child view and inflate a new view. Right now it crashes after the string array finishes displaying on multiple clickings of the "next" button.
How can I get this to work?

Ah, yes, I see it now. You can't do this:
myString[-1]
The index -1 does not exist in arrays. What are you trying to do? Perhaps myString[count - 1]?
