Radio Button and TextField Android-studio - android-studio

Question

How can I make a radio button group and a TextField, so that whenever I click on TextField the radio button automatically changes from one to another?
Please give me a block of code for this.

Answer 1

If I understood your question correctly, you want the radioButton checked status change once the textView click. You can achieve by this way.
public class MainActivity extends Activity {
private RadioGroup radioSexGroup;
private RadioButton radioSexButton,male,female;
private TextView btnDisplay;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
radioSexGroup=(RadioGroup)findViewById(R.id.radioGroup);
btnDisplay=(TextView)findViewById(R.id.textView3);
male = (RadioButton)findViewById(R.id.radioButton);
female=(RadioButton)findViewById(R.id.radioButton2);
btnDisplay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int selectedId=radioSexGroup.getCheckedRadioButtonId();
radioSexButton=(RadioButton)findViewById(selectedId);
if(radioSexButton.getText().toString().equals("Male"))
{
female.setChecked(true);
}
else
{
male.setChecked(true);
}
}
});
}
}
