Let me try this again with better phrasing. I am very new at this; I am trying to pass the value result of checkbox’s to another activity. I have tried it a few different ways without success and I would be grateful for some direction.
I know how to make a “Toast” with the result, that is not what I want it to do. I want the checkbox results will appear in a textview in another activity. If someone could help me out with some hints on how to accomplish that task I would be grateful, I am sorry to bother everyone with such unchallenging questions.
I have read a couple books and watched some tutorials but my skills are still lacking. The books are as repetitive and redundant as the tutorials (buttons and layouts, etc.).

In your first activity:
Intent i=new Intent(YourClassName.this,ApplianceMessage.class);
i.putExtra("selected",vendor);
startActivity(i);
In your second Activity:
String selecteditem=getIntent().getExtras().getString("selected");
textview.setText(selecteditem);
You're putting a String Extra in the intent. Just get it by:
getIntent().getStringExtra("chbxshirleys");

I need help with my code. Let me try to explain the problem:
At the first activity I have two fields where I'll set values from an Enum, for this I made a button for each field that basically shows me another activity, calls the value and brings it to the main activity. Still in the first activity I have a button that starts another activity and (at the same time) take all the values from the enum end sends to another activity. The point is, everything is working, but this last button no, when I click it the app crashes. What is happening and how can I solve it?
Here goes the code of the first activity:
public class MenuInicial extends AppCompatActivity {
public static final int CONSTANTE_BANZO = 1;
Button escolherM;
Button escolherB;
Button next;
TextView campoM;
TextView campoB;
Intent intent1;
Intent intent2;
Intent intentBundle;
Intent intentNext;
Bundle bundle;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu_inicial);
intent1 = new Intent(MenuInicial.this, Montante.class);
campoM = (TextView) findViewById(R.id.fieldM);
escolherM = (Button) findViewById(R.id.chooseM);
String perfilM = getIntent().getExtras().getString("nameM");
campoM.setText(perfilM);
escolherM.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v){
startActivity(intent1);
}
});
intent2 = new Intent(MenuInicial.this, Banzo.class);
campoB = (TextView) findViewById(R.id.fieldB);
escolherB = (Button) findViewById(R.id.chooseB);
escolherB.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v){
startActivityForResult(intent2, CONSTANTE_BANZO);
}
});
next = (Button) findViewById(R.id.prosseguir);
intentBundle = new Intent(MenuInicial.this, ConferenciaDosDados.class);
intentNext = new Intent(MenuInicial.this, Dados.class);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String perfilM = getIntent().getExtras().getString("nameM");
Float baseMt = getIntent().getExtras().getFloat("baseM");
Float alturaMt = getIntent().getExtras().getFloat("alturaM");
String perfilB = getIntent().getExtras().getString("nameB");
Float baseBz = getIntent().getExtras().getFloat("baseB");
Float alturaBz = getIntent().getExtras().getFloat("alturaB");
bundle.putString("nomeM",perfilM);
bundle.putFloat("baseM",baseMt);
bundle.putFloat("alturaM",alturaMt);
bundle.putString("nomeB",perfilB);
bundle.putFloat("baseB",baseBz);
bundle.putFloat("alturaB",alturaBz);
intentBundle.putExtras(bundle);
startActivity(intentBundle);
startActivity(intentNext);
}
});
}
protected void onActivityResult(int codigo, int resultado, Intent intent){
if(codigo == CONSTANTE_BANZO){
Bundle bundleB = intent.getExtras();
if(bundleB != null){
String perfilB = bundleB.getString("nameB");
campoB.setText(perfilB);
}
}
}
}
next = (Button) findViewById(R.id.prosseguir);
intentBundle = new Intent(MenuInicial.this, ConferenciaDosDados.class);
intentNext = new Intent(MenuInicial.this, Dados.class);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String perfilM = getIntent().getExtras().getString("nameM");
Float baseMt = getIntent().getExtras().getFloat("baseM");
Float alturaMt = getIntent().getExtras().getFloat("alturaM");
String perfilB = getIntent().getExtras().getString("nameB");
Float baseBz = getIntent().getExtras().getFloat("baseB");
Float alturaBz = getIntent().getExtras().getFloat("alturaB");
bundle.putString("nomeM",perfilM);
bundle.putFloat("baseM",baseMt);
bundle.putFloat("alturaM",alturaMt);
bundle.putString("nomeB",perfilB);
bundle.putFloat("baseB",baseBz);
bundle.putFloat("alturaB",alturaBz);
intentBundle.putExtras(bundle);
startActivity(intentBundle);
startActivity(intentNext);
}
});
Which activity do you want to go to? choose one. When you do, you can get those extras then when you need to goto the other activity, you can put those extras there too.
A better way to do it is to create a model (constructor with setters and getters) and put these in a list. At that point you can loop through the list and take what you need. It all depends on what you are doing though as the list will not be instantiated like intent extras would be.
Or, you can use SharedPref which is similar to a HashMap (which is also similar to the Intent Extras). SharedPref will store the key and value on the phones cache and then you can pull from that when you need it. Again, keep in mind that if the user clears the cache on the app, then it'll delete those shared pref.
Finally, you can also use a database such as Parse Server or Firebase.
problem: I set point breaks at the following code:
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_NAME, workoutName);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_DAYS, workoutDays);
, both showed up as null when I ran the app in debug mode. workoutName contains a simple String that is passed to a new activity, whereas workoutDays constains an array of String.
the full code is provided below:
public class CreateWorkoutActivity extends Activity {
public final String TAG = this.getClass().getSimpleName();
protected String[] workoutDays = new String[7];
protected String workoutName;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_workout);
Button mNextButton = (Button) findViewById(R.id.next_button1);
CheckBox satBox = (CheckBox) findViewById(R.id.sat_checkbox);
CheckBox sunBox = (CheckBox) findViewById(R.id.sun_checkbox);
CheckBox monBox = (CheckBox) findViewById(R.id.mon_checkbox);
CheckBox tuesBox = (CheckBox) findViewById(R.id.tues_checkbox);
CheckBox wedBox = (CheckBox) findViewById(R.id.wed_checkbox);
CheckBox thursBox = (CheckBox) findViewById(R.id.thurs_checkbox);
CheckBox friBox = (CheckBox) findViewById(R.id.fri_checkbox);
final EditText mWorkoutName = (EditText) findViewById(R.id.workout_name1);
workoutName = mWorkoutName.getText().toString();
Log.i(TAG, workoutName);
if (satBox.isChecked()) {
workoutDays[0] = new String(satBox.getText().toString());
}
if (sunBox.isChecked()) {
workoutDays[1] = new String(sunBox.getText().toString());
}
if (monBox.isChecked()) {
workoutDays[2] = new String(monBox.getText().toString());
}
if (tuesBox.isChecked()) {
workoutDays[3] = new String(tuesBox.getText().toString());
}
if (wedBox.isChecked()) {
workoutDays[4] = wedBox.getText().toString();
}
if (thursBox.isChecked()) {
workoutDays[5] = satBox.getText().toString();
}
if (friBox.isChecked()) {
workoutDays[6] = friBox.getText().toString();
Log.i(TAG, workoutDays[6]);
}
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i(TAG, workoutDays.toString());
Intent intent = new Intent(CreateWorkoutActivity.this, WorkoutRoutinesActivity.class);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_NAME, workoutName);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_DAYS, workoutDays);
Log.i(TAG, workoutDays.toString());
startActivity(intent);
}
});
}
The problem is not in the intent, but in the way you obtain workoutName (this is the null value). You create the activity, set up final EditText mWorkoutName = (EditText) findViewById(R.id.workout_name1); and then immediately ask for the input value through workoutName = mWorkoutName.getText().toString();, but at this time the user still hasn't entered anything. You should put that second line in the listener below (so its activated only after the user presses mNextButton. It's a good idea to put some check after it and send a message to user that they need to fill in that field (if it is indeed necessary).
Looks like the values for workoutName and workoutDays are not filled in initially when the view is created. You should move retrieving the value from the text fields to your onClickListener function.
you checking the CheckBox and EditText in onCreate, absolutely the EditText will be empty and all CheckBox it not checked
I'm making a quiz app. User has to finish the phrase shown on display and write the name of the car in the edittext, after pushing on button, if the answer right, edittext become green, if doesn't, become red. If all answers right (green), intent move on next activity.
I have some difficulties with if statement edit text become red even the answer was right. Also how to make INTENT to move on next activity if all right, if not it doesn't move?
public class MainActivity extends AppCompatActivity {
EditText et_one_one, et_one_two, et_one_three;
Button buttonCheck;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_one_one = (EditText) findViewById(R.id.et_one_one);
et_one_two = (EditText) findViewById(R.id.et_one_two);
et_one_three = (EditText) findViewById(R.id.et_one_three);
final String t1 = et_one_one.getText().toString();
final String t2 = et_one_two.getText().toString();
final String t3 = et_one_three.getText().toString();
buttonCheck = (Button) findViewById(R.id.buttonCheck);
buttonCheck.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (t1.equals("maserati")){
et_one_one.setBackgroundColor(Color.GREEN);
}
else {
et_one_one.setBackgroundColor(Color.RED);
}
if (t2.equals("mercedes")){
et_one_two.setBackgroundColor(Color.GREEN);
}
else{
et_one_two.setBackgroundColor(Color.RED);
}
if (t3.equals("bmw")){
et_one_three.setBackgroundColor(Color.GREEN);
}
else{
et_one_three.setBackgroundColor(Color.RED);
}
}
});
}
}
You're changing the color of just the et_one_one each time in your if else statements. Shouldn't it be for different edittexts?
buttonCheck.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean allAnswersCorrect = true;
String t1 = et_one_one.getText().toString();
String t2 = et_one_two.getText().toString();
String t3 = et_one_three.getText().toString();
if (t1.equals("maserati")){
et_one_one.setBackgroundColor(Color.GREEN);
}
else {
allAnswersCorrect = false;
et_one_one.setBackgroundColor(Color.RED);
}
if (t2.equals("mercedes")){
et_one_two.setBackgroundColor(Color.GREEN);
}
else{
allAnswersCorrect = false;
et_one_two.setBackgroundColor(Color.RED);
}
if (t3.equals("bmw")){
et_one_three.setBackgroundColor(Color.GREEN);
}
else{
allAnswersCorrect = false;
et_one_three.setBackgroundColor(Color.RED);
}
if(allAnswersCorrect){
Intent intent = new Intent(YourActivity.this, YourSecondActivity.class);
startActivity(intent);
}
}
});
Maintain a allAnswersCorrect boolean to check whether your answers are correct or not. If all are correct the move to your next activity.
You should use t2.equals("maserati"), and it will be ok.
I am very new at this; I am trying to pass the result of checkbox’s to another activity. I have tried it a few different ways without success and I would be grateful for some direction. Please any help would be great. Thank you

if (chbxcamren.isChecked())
{
vendor += chbxcamren.getText();
}
if (chbxricks.isChecked())
{
vendor += chbxricks.getText();
}
}
});
}
I think you can use
intent.putExtra("String name", chbxshirleys.isChecked());
In Activity get boolean value
First of all please learn more about checkboxes on android from here:
http://developer.android.com/guide/topics/ui/controls/checkbox.html
And for good example you can look that one:
http://www.mkyong.com/android/android-checkbox-example/
And for pass the result other activity use extras for activity.
I want to pass some data from one activity to another and set it in dynamically created TextView over frame layout of that activity..I'm using intent for that but at second activity the data is not getting extracted..Can any one tell me the simple way for this..
Following is my code..

public class Hidden extends Activity implements OnClickListener {
Button btnnameadd, btnnameremove, btnmobileadd, btnmobileremove, btndone;

}
#Override
public void onClick(View v) {
jump=new Intent(Hidden.this,Framelayout.class);
if(v.getId()==R.id.buttonnameadd)
{
String strname=etname.getText().toString();
Log.d("Log",strname);
jump.putExtra("Name",strname);
}else if(v.getId()==R.id.buttonnameremove)
{
btnnameremove.setEnabled(false);
llname.removeView(findViewById(R.id.editTextname));
}else if(v.getId()==R.id.buttonmobileadd)
{
String strmobile=etmobile.getText().toString();
Log.d("Log",strmobile);
jump.putExtra("Mobile",strmobile);
Log.d("LOG",jump.putExtra("Mobile",strmobile).toString());
}else if(v.getId()==R.id.buttonmobileremove)
{
llmobile.removeView(findViewById(R.id.editTextmobile));
}else if(v.getId()==R.id.buttondone)
{
Log.d("LOG","1");
startActivity(jump);
}
}
}
FrameLayout.java
public class Framelayout extends Activity implements OnClickListener {
FrameLayout frameLayout;
Button b2,b3;
//private ProgressDialog pDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_framelayout);
frameLayout = (FrameLayout)findViewById(R.id.f1);
b2=(Button)findViewById(R.id.button2);
b3=(Button)findViewById(R.id.buttonload);
b2.setOnClickListener(this);
b3.setOnClickListener(this);
}
public void onClick(View v) {
if(v.getId()==R.id.button2){
Intent i=new Intent(Framelayout.this,Hidden.class);
startActivity(i);
}else if(v.getId()==R.id.buttonload){
Log.d("Log",getIntent().getStringExtra("Name"));
editframelayout();
}
}
private void editframelayout() {
String name=getIntent().getExtras().getString("Name");
String mobile=getIntent().getExtras().getString("Mobile");
TextView tvname=new TextView(this);
tvname.setText(name);
tvname.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
tvname.setGravity(Gravity.CENTER);
TextView tvmobile=new TextView(this);
tvmobile.setText(mobile);
tvmobile.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
tvmobile.setGravity(Gravity.CENTER);
frameLayout.addView(tvname);
frameLayout.addView(tvmobile);
}
}
You must use one of putExtra() overloaded methods of the intent instance you created to add your data.
Here is a sample:
Intent intent = new Intent(this, SignoutActivity.class); // # this parameter is the context of the caller
intent.putExtra("PARAM_TEXTBOX_TEXT", textboxText);
startActivity(intent);
Edit for the code you added, your design is very poor and doesn't accomplish what is intended.
Every time you click a Button a new instance of Intent is created. you are calling startActivity() only in single case:
else if(v.getId()==R.id.buttondone)
{
Log.d("LOG","1");
startActivity(jump);
}
Now you assume that the parameters added in previous button clicks are still there, but they aren't. When you click buttondone you create a new instance of Intent with no extras at all.
You can work this around as follows:
...
else if(v.getId()==R.id.buttondone)
{
String strname = etname.getText().toString();
if (strname != null && !strname.equals(""))
{
jump.putExtra("Name",strname);
}
String strmobile = etmobile.getText().toString();
if (strmobile != null && !strmobile.equals(""))
{
jump.putExtra("Mobile",strmobile);
}
startActivity(jump);
}
It still isn't well structured, but might do the trick for you
Use getIntent().getStringExtra("Name") instead of getIntent().getExtras().getString("Name");
getIntent().getStringExtra("Name")
