Answer 1

试试这个..

LinearLayout layout_name = (LinearLayout) findViewById(R.id.layout_name);
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].setId(i);//Setting id for the RadioButton
            rb[i].setText("Test");
        }
        rg.check(3);//Checking pirticular RadioButton with id
        // 3 is that RadioButton Id name
        layout_name.addView(rg);//you add the whole RadioGroup to the layout

修改

 int selected = rg.getCheckedRadioButtonId();
 String type =rb[selected].getText().toString(); 
 Log.d("type", type);
