Android Radio Button

Question

I have a switch group on Android that looks something like this:

Choose a color:

• Red
• blue
• Orange
• Green

I need to get the selected switch, as well as its value.

I have 4 radio objects in this way in the radio group rg

 rb1a=(RadioButton)findViewById(R.id.rb1a); rb1b=(RadioButton)findViewById(R.id.rb1b); rb1c=(RadioButton)findViewById(R.id.rb1c); rb1d=(RadioButton)findViewById(R.id.rb1d); tv1=(TextView)findViewById(R.id.tv1); next1=(Button)findViewById(R.id.next1); rg=(RadioGroup)findViewById(R.id.rg); // I have error after this line.please help rg.setOnCheckedChangeListener(new OnCheckedChangeListener() { public void onCheckedChanged(RadioGroup group, int checkedId) { } @Override public void onCheckedChanged(CompoundButton arg0, boolean arg1) { // TODO Auto-generated method stub } }); 

Answer 1

You can test the radion button using the isChecked() function.

for ex:

 if(radio1_red.isChecked()) { txtView.setText("Red button is checked"); } 

Take a look at the Example .

You can also link to this Page - Form Stuff listed on android-sdk pages.

Do this to get the selected switch, as well as its value:

  private OnClickListener radio_listener = new OnClickListener() { public void onClick(View v) { // Perform action on clicks RadioButton rb = (RadioButton) v; Toast.makeText(HelloFormStuff.this, rb.getText(), Toast.LENGTH_SHORT).show(); } }; 

Answer 2

as you can see in the Android documentation http://developer.android.com/reference/android/widget/RadioGroup.OnCheckedChangeListener.html OnCheckedChangeListener has only the onCheckedChanged method (RadioGroup group, int checkedId) and does not contain the public void onCheckedChangedound method arg0, boolean arg1) → delete it and try again.

Here you will find an example: http://developer.android.com/guide/tutorials/views/hello-formstuff.html
