Question

I've got a method in which i have a list of values: /** * ISO * */ public void getISO(View view) { // Open dialog with radio buttons List

Solution 1:

best and easy way......

voiddialog(){

        AlertDialog.Builderalt_bld=newAlertDialog.Builder(this);
        //alt_bld.setIcon(R.drawable.icon);
        alt_bld.setTitle("Select a Group Name");
        alt_bld.setSingleChoiceItems(grpname, -1, newDialogInterface
                .OnClickListener() {
            publicvoidonClick(DialogInterface dialog, int item) {
                Toast.makeText(getApplicationContext(),
                        "Group Name = "+grpname[item], Toast.LENGTH_SHORT).show();
                dialog.dismiss();// dismiss the alertbox after chose option

            }
        });
        AlertDialogalert= alt_bld.create();
        alert.show();


///// grpname is a array where data is stored... 


    }

Solution 2:

Call showRadioButtonDialog() from the button.

This is just an example:

privatevoidshowRadioButtonDialog() {

 // custom dialog

  final Dialog dialog = new Dialog(this);
  dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
  dialog.setContentView(R.layout.dialog_layout);
  List<String> stringList=new ArrayList<>();  // here is listfor(int i=0;i<2;i++) {
          if (i==0){
              stringList.add("Number Mode");
          }else {
              stringList.add("Character Mode");
          }

      }

      RadioGroup rg = (RadioGroup) dialog.findViewById(R.id.radioGroup);

      for(int i=0;i<stringList.size();i++){
            RadioButton rb=new RadioButton(this); // dynamically creating RadioButton and adding to RadioGroup.
            rb.setText(stringList.get(i));
            rg.addView(rb);
      }
}

Your layout view might be:radiobutton_dialog.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><RadioGroupandroid:id="@+id/radio_group"android:layout_width="wrap_content"android:layout_height="match_parent"android:layout_gravity="center_vertical"android:orientation="vertical"></RadioGroup></LinearLayout>

Note: you can customize your dialog view (like setting title, message etc.)

Edit: To retrieving value of the selected RadioButton you have to implement setOnCheckedChangeListener listener for your RadioGroup as :

 rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

            @Override
            publicvoidonCheckedChanged(RadioGroup group, int checkedId) {
                 int childCount = group.getChildCount();
                 for (int x = 0; x < childCount; x++) {
                    RadioButton btn = (RadioButton) group.getChildAt(x);
                    if (btn.getId() == checkedId) {
                         Log.e("selected RadioButton->",btn.getText().toString());

                    }
                 }
            }
        });

Excerpt from (Adding a persistent multiple-choice or single-choice list)

mSelectedItems = new ArrayList();  // Where we track the selected items
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Set the dialog title
builder.setTitle(R.string.pick_toppings)
// Specify the list array, the items to be selected by default (null for none),// and the listener through which to receive callbacks when items are selected
       .setMultiChoiceItems(R.array.toppings, null,
                  new DialogInterface.OnMultiChoiceClickListener() {
           @Override
           publicvoidonClick(DialogInterface dialog, int which,
                   boolean isChecked) {
               if (isChecked) {
                   // If the user checked the item, add it to the selected items
                   mSelectedItems.add(which);
               } elseif (mSelectedItems.contains(which)) {
                   // Else, if the item is already in the array, remove it 
                   mSelectedItems.remove(Integer.valueOf(which));
               }
           }
       })
// Set the action buttons
       .setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
           @Override
           publicvoidonClick(DialogInterface dialog, int id) {
               // User clicked OK, so save the mSelectedItems results somewhere// or return them to the component that opened the dialog
               ...
           }
       })
       .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
           @Override
           publicvoidonClick(DialogInterface dialog, int id) {
               ...
           }
       });

return builder.create();

No custom view is necessary.

Solution 4:

This worked for me:

final CharSequence[] items = {"Option-1", "Option-2", "Option-3", "Option-4"};

AlertDialog.Builderbuilder=newAlertDialog.Builder(ShowDialog.this);
builder.setTitle("Alert Dialog with ListView and Radio button");
builder.setIcon(R.drawable.icon);
builder.setSingleChoiceItems(items, -1, newDialogInterface.OnClickListener() {
    publicvoidonClick(DialogInterface dialog, int item) {
 Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
    }
});

builder.setPositiveButton("Yes",
 newDialogInterface.OnClickListener() {
  publicvoidonClick(DialogInterface dialog, int id) {
   Toast.makeText(ShowDialog.this, "Success", Toast.LENGTH_SHORT).show();
  }
 });
builder.setNegativeButton("No",
 newDialogInterface.OnClickListener() {
  publicvoidonClick(DialogInterface dialog, int id) {
   Toast.makeText(ShowDialog.this, "Fail", Toast.LENGTH_SHORT).show();
  }
 });
AlertDialogalert= builder.create();
alert.show();

Solution 5:

Kotlin version:

fundialog() {
    val options = arrayOf("option1", "option2")
    var selectedItem = 0val builder = AlertDialog.Builder(this)
    builder.setTitle("Select an option")
    builder.setSingleChoiceItems(options
            , 0, { dialogInterface: DialogInterface, item: Int ->
        selectedItem = item
    })
    builder.setPositiveButton(R.string.accept, { dialogInterface: DialogInterface, p1: Int ->
        Toast.makeText(getApplicationContext(),
                "selected item = " + options[selectedItem], Toast.LENGTH_SHORT).show();
        dialogInterface.dismiss()
    })
    builder.setNegativeButton(R.string.cancel, { dialogInterface: DialogInterface, p1: Int ->
        dialogInterface.dismiss()
    })
    builder.create()
    builder.show();
}
