Question

即時創建RadioGroup，裏面那radio button。 如何獲取radio button中的選定值以存儲在數組列表中？

TableLayout ch = (TableLayout) findViewById(R.id.tablechild); 
TableRow row2 = new TableRow(Edittextsample.this); 
TextView m = new TextView(Edittextsample.this); 
m.setText("Meals"); 
RadioGroup rg2 = new RadioGroup(Edittextsample.this); 
rg2.setOrientation(TableLayout.HORIZONTAL); 
RadioButton r = new RadioButton(Edittextsample.this) 
r.setText("Veg"); 
r.setTextSize(12); 
rg2.addView(r); 

RadioButton r1 = new RadioButton(Edittextsample.this) 
r1.setText("Non-Veg"); 
r1.setTextSize(12); 
rg2.addView(r); 
ch.addView(row2,new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 

Answer 1

int selectedRadioId = rg2.getCheckedRadioButtonId(); 
RadioButton selectedRadioButton = rg2.findViewById(selectedRadioId); 
String selectedText = selectedRadioButton.getText(); // "Veg" or "Non-veg"
