I am generating the radio buttons dynamically from server returned json data in android.
I can display the radio buttons in radio group. Also can get id of each radio button.
But when I click on the next radio buttons all are stayed as selected. None of them are unchecked.
As the radio numbers are generated dynamically so it sizes will vary.
My code snippets :
if(type.equals("radio_buttons")){
String optionName = regData.getOption();
optionName = Character.toString(optionName.charAt(0)).toUpperCase()+optionName.substring(1);
List listItem = new ArrayList();
listItem.add(optionName);
final RadioGroup rg = new RadioGroup(getActivity()); //create the RadioGroup
rg.setOrientation(RadioGroup.HORIZONTAL);
final int radioSize = listItem.size();
final RadioButton[] rb = new RadioButton[radioSize];
for(int i=0; i<radioSize; i++){
rb[i] = new RadioButton(getActivity());
rg.addView(rb[i]); //the RadioButtons are added to the radioGroup instead of the layout
rb[i].setId(i);
rb[i].setText(optionName);
}
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
for(int j = 0; j<radioSize; j++){
rg.removeViewAt(checkedId);
}
/*
switch (checkedId)
{
case 1:
Toast.makeText(OnsiteRegistrationFragment.this.getActivity(), "VIEW ID " + checkedId, Toast.LENGTH_LONG).show();
case 2:
Toast.makeText(OnsiteRegistrationFragment.this.getActivity(), "VIEW ID " + checkedId, Toast.LENGTH_LONG).show();
}*/
}
});
this.linearLayout.addView(rg);
}
How can i clear/uncheck the other radio buttons when one radio button is selected in android?
LinkedList<RadioButton> radiobuttons
At the time of creating button add radiobuttons in radiobuttons in your for loop.
for (int i = 0; i < radioSize.size(); i++) {
RadioButton rb;
rb = radiobuttons.get(i);
rg.removeView(rb);
}

I need to add RadioGroups and RadioButtons dynamically and generate desired view and implement onCheckChangedListener() on my dynamically created RadioGroup . The problem is, when a newly added button is checked, it is not unchecked when I am clicking other button. I have already checked this - Issue in radiogroup while adding radiobuttons dynamically , but to no avail.
I am working in a fragment and adding views dynamically inside it. The radiobuttons do not exhibit check changed behavior. Please help me to sort this out.
//optionsGroup(RadioGroup),optionButton(RadioButton)
optionsGroup = new RadioGroup(getActivity());
optionsGroup.setId(radioGroupCount);
optionsGroup.setPadding(20, 20, 20, 20);
optionsGroup.setLayoutParams(layparams);
radioGroupList.add(optionsGroup);
ArrayList<Options> RadioButtonOptions = question.getQuestionOptions().getOptions();
for (int i = 0; i < RadioButtonOptions.size(); i++) {
optionButton = new RadioButton(getActivity());
optionButton.setId(i);
optionButton.setText(RadioButtonOptions.get(i).getOptionValue());
optionsGroup.addView(optionButton);
optionsGroup.clearCheck();
}
optionsGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
for(int rb=0;rb<optionsGroup.getChildCount();rb++){
RadioButton btn = (RadioButton) optionsGroup.getChildAt(rb);
if(checkedId==btn.getId()){
radioGroupAnswerList.clear();
radioGroupAnswerList.add(btn.getText().toString());
return;
}
}
}
});
holderlayout.addView(optionsGroup);
I think problem is you are adding view before assigning its listener . so please try this.
for (int i = 0; i < RadioButtonOptions.size(); i++) {
optionButton = new RadioButton(getActivity());
optionButton.setId(i);
optionButton.setText(RadioButtonOptions.get(i).getOptionValue());
optionsGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
for(int rb=0;rb<optionsGroup.getChildCount();rb++){
RadioButton btn = (RadioButton) optionsGroup.getChildAt(rb);
if(checkedId==btn.getId()){
radioGroupAnswerList.clear();
radioGroupAnswerList.add(btn.getText().toString());
return;
}
}
}
});
optionsGroup.addView(optionButton);
}
You need to uncheck other radiobutton if one radio button clicked right? and all this will be dynamically created radiobutton and radio groupe.. then you have to do this..
//optionsGroup(RadioGroup),optionButton(RadioButton)
optionsGroup = new RadioGroup(getActivity());
optionsGroup.setId(radioGroupCount);
optionsGroup.setPadding(20, 20, 20, 20);
optionsGroup.setLayoutParams(layparams);
radioGroupList.add(optionsGroup);
ArrayList<Options> RadioButtonOptions = question.getQuestionOptions().getOptions();
for (int i = 0; i < RadioButtonOptions.size(); i++) {
optionButton = new RadioButton(getActivity());
optionButton.setId(i);
optionButton.setText(RadioButtonOptions.get(i).getOptionValue());
optionsGroup.addView(optionButton);
optionsGroup.clearCheck();
}
optionsGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
for(int rb=0;rb<optionsGroup.getChildCount();rb++){
RadioButton btn = (RadioButton) optionsGroup.getChildAt(rb);
if(checkedId==btn.getId()){
radioGroupAnswerList.clear();
radioGroupAnswerList.add(btn.getText().toString());
optionsGroup.clearCheck();
if (isChecked) {
optionsGroup.check(btn.getId());
}
return;
}
}
}
});
holderlayout.addView(optionsGroup);
I have created the dynamic view. That view contains two edittext and one radio group. when I click the add button the view is added to the layout. Now I got a confusion, how to get values from these type of dynamic views. I tried but it doesn't work. when I add the two or more views, the loop does not find the next views values. I want to add that values to ArrayList. This is code:
private void addDynamicViews() {
EditText name = new EditText(this);
EditText mobile = new EditText(this);
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
p.setMargins(10, 10, 5, 5);
name.setLayoutParams(p);
name.setBackgroundResource(R.drawable.edittext_box);
name.setHint("Enter Name");
studentslayout.addView(name);
mobile.setLayoutParams(p);
mobile.setBackgroundResource(R.drawable.edittext_box);
mobile.setHint("Enter Mobile No");
studentslayout.addView(mobile);
/* radioGroup - Radio Group
maleButton,femaleButton - Radio Buttons
studentslayout - Linear Layout */
radioGroup = new RadioGroup(this);
radioGroup.setOrientation(RadioGroup.VERTICAL);
maleButton = new RadioButton(this);
maleButton.setText("Male");
radioGroup.addView(maleButton);
femaleButton = new RadioButton(this);
radioGroup.addView(femaleButton);
femaleButton.setText("Female");
studentslayout.addView(radioGroup);
}
How to take all dynamic edittext and radio group values ?
I tried this code But unfortunately it stopped.
#Override
public void onClick(View v) {
String[] array = new String[studentslayout.getChildCount()];
int count = studentslayout.getChildCount();
for (int i=0; i < studentslayout.getChildCount(); i++){
editText = (EditText)studentslayout.getChildAt(i);
array[i] = editText.getText().toString();
RadioButton radValues = (RadioButton) studentslayout.getChildAt(i);
array[i] = radValues.getText().toString();
}
}
RadioButton radValues = (RadioButton) studentslayout.getChildAt(i);
You have added radioGroup and are expecting radiobutton. Also since you are looping, you should check the type of the view.
You can try something like this:
int childCount = studentslayout.getChildCount();
for (int i = 0; i < childCount; i++) {
View childView = studentslayout.getChildAt(i);
if (childView instanceof EditText) {
EditText editText = (EditText) childView;
String text = editText.getText().toString();
//use text
} else if (childView instanceof RadioGroup) {
RadioGroup radioGroup = (RadioGroup) childView;
int radioCount = radioGroup.getChildCount();
for (int j = 0; j < radioCount; j++) {
RadioButton radioButton = (RadioButton) radioGroup.getChildAt(i);
//use radioButton.
}
}
}
In my app i have created list view of checkbox in linear layout and i have created dynamic radio group of three radio button.when user click on any checkbox than radio group will be created at the end. but i want to create this radio group just below the clicked checked box. i am trying to set cursor position but not able to do.i don't have any idea what to do for this.
this is part of main.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ViewGroup checkboxContainer = (ViewGroup) findViewById(R.id.checkbox_container);
for (int i = 0; i < 25; i++) {
final CheckBox checkBox = new CheckBox(this);
checkBox.setText(Oils_and_Condiments[i]);
checkboxContainer.addView(checkBox);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked)
{
for (int i = 0; i < Oils_and_Condiments.length; i++) {
String a= (String) checkBox.getText();
if(a==Oils_and_Condiments[i])
{
RadioGroup rg = create_rb(i);
checkboxContainer.get
checkboxContainer.addView(rg);
rg.setVisibility(View.VISIBLE);
//rg.getChildAt(i).setVisibility(View.VISIBLE);
}
RadioGroup create_rb(int a ){
final RadioGroup radiogp = new RadioGroup(this);
radiogp.setOrientation(RadioGroup.HORIZONTAL);
RadioButton rb0 = new RadioButton(this);
RadioButton rb1 = new RadioButton(this);
RadioButton rb2 = new RadioButton(this);
rb0.setText("1KG");
rb0.setTextSize(10);
rb1.setText("2KG");
rb1.setTextSize(10);
rb2.setText("3KG");
rb2.setTextSize(10);
radiogp.addView(rb0);
radiogp.addView(rb1);
radiogp.addView(rb2);
//checkboxContainer.addView(radiogp);
return radiogp;
}
Hi i created dynamic radiogroup with radiobutton.Now i want to get values from dynamic radiogroup. Below is my code
final RadioGroup rg = new RadioGroup(this);
rg.setId(questionNo);
RadioButton[] rb = new RadioButton[answers.length()];
for (int i = 0; i < answers.length(); i++) {
JSONObject answerObject = answers.getJSONObject(i);
rb[i] = new RadioButton(this);
rb[i].setText(answerObject.getString("AnswerValue"));
rb[i].setId(answerObject.getInt("AnswerId"));
rg.addView(rb[i]);
}
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup arg0, int arg1) {
int selectedId = rg.getCheckedRadioButtonId();
Log.i("ID", String.valueOf(selectedId));
}
});
Button click event
submit_button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(rg.getCheckedRadioButtonId()!=-1){
int id= rg.getCheckedRadioButtonId();
View radioButton = rg.findViewById(id);
int radioId = rg.indexOfChild(radioButton);
RadioButton btn = (RadioButton) rg.getChildAt(radioId);
String selection = (String) btn.getText();
Log.i("selection", selection);
}
}
});
I am getting only last index of the radio group.
I know it's too late, But this may help someone else
While creating your Dynamic Radiobutton Group, Create a parent layout(Linear layout or Relative Layout)
All radio groups will be the child of that Layout and all radio button will be a child of the specific radio group.
Creating No of Dynamic Radio Group
Create all Dynamic radio group in a parent layout
Add all radio button to a group
Add all radio group to the parent layout
public RadioButton[] rb;
public RadioGroup grp;
public LinearLayout layoutmain; //Parent layout
for(int i=0;i<qus.size();i++) //No of Questions
{
rb = new RadioButton[size];
grp = new RadioGroup(this);
grp.setId(a+qus.get(i).qusetionId);
for(int j=0;j<qus.get(i).choices.size();j++) //No of Radio button in radio group
{
rb[j] = new RadioButton(this);
rb[j].setText(qus.get(i).choices.get(j).getChoiceText());
grp.addView(rb[j]); // adding button to group
}
layoutmain.addView(grp); // adding group to layout
}
Retrieve All selected button task
From parent, layout get all child
Find all radio group using the child Instance
Create an object for that radio group
using that object get the selected radio button
Button bt = (Button) findViewById(R.id.button);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
for(int i=0;i<layoutmain.getChildCount();i++) //From the parent layout (Linear Layout) get the child
{
View child = layoutmain.getChildAt(i);
if(child instanceof RadioGroup) //Check weather its RadioGroup using its INSTANCE
{
RadioGroup rg = (RadioGroup) child; //create a RadioButton for each group
int selectedId = rg.getCheckedRadioButtonId(); // get the selected button
RadioButton radiochecked = (RadioButton) findViewById(selectedId);
Log.e("Radio",radiochecked.getText().toString()); //from the button get the selected text
}
}
} });
I want to create a series of radio buttons which correspond to an array of strings within an Android app. The radio buttons should toggle content to be displayed from the array. How do I do this?
You must add the radio buttons to a RadioGroup and then the RadioGroup to the layout
I miss some information like what is submit, but your code should look like:
private void createRadioButton() {
final RadioButton[] rb = new RadioButton[5];
RadioGroup rg = new RadioGroup(this); //create the RadioGroup
rg.setOrientation(RadioGroup.HORIZONTAL);//or RadioGroup.VERTICAL
for(int i=0; i<5; i++){
rb[i] = new RadioButton(this);
rg.addView(rb[i]); //the RadioButtons are added to the radioGroup instead of the layout
rb[i].setText("Test");
}
ll.addView(rg);//you add the whole RadioGroup to the layout
ll.addView(submit);
submit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
for(int i = 0; i < 5; i++) {
rg.removeView(rb[i]);//now the RadioButtons are in the RadioGroup
}
ll.removeView(submit);
Questions();
}
});
}
Another code for dynamically creating the radiobutton
<TableRow>
<RadioGroup
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="#+id/radiobuttons">
</RadioGroup>
</TableRow>
Code:
public void makeRadioButtons(Vector tmpVector, int i, LinearLayout.LayoutParams lp)
{
RadioButton rb = new RadioButton(this);
rb.setText((String) tmpVector.elementAt(i));
//rg is private member of class which refers to the radio group which I find
//by id.
rg.addView(rb, 0, lp);
}
