android radiobutton button accept

Question

I have a problem with button Set Color . Set Color is to activate the selected RadioButton . For example, selecting the first radiobutton and when you click "Set Color" is the background color change to red. Here is my Android Studio codes.

UPDATE

My app working process now:

When I click for example on first RadioButton my textview background color change automatically. Its skipping my "Set Color" button.

My intended app working.

When I click for example on first RadioButton and after that I accept my choose clicking "Set Color" button my textview background color change.

Answer 1

Create field for saving textview color in, and just save in it new value on onRadioClicked . After you click your "Set Color" call your textView.setBackgroundColor(savedColor) .

Answer 2

Try the following

RadioButton radioButton1, radioButton2, radioButton3;
Button setColorButton, cancelButton;
TextView textwju;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.radiobutton_example);


    radioButton1   = (RadioButton) findViewById(R.id.czerwonyguzik);
    radioButton2   = (RadioButton) findViewById(R.id.bialyguzik);
    radioButton3   = (RadioButton) findViewById(R.id.niebieskiguzik);
    setColorButton = (Button) findViewById(R.id.setcolor);
    cancelButton = (Button) findViewById(R.id.cancel);
    textwju        = (TextView) findViewById(R.id.textwju);



    setColorButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if(radioButton1.isChecked()) {
                textwju.setBackgroundColor(getResources().getColor(R.color.blue));
            } else if(radioButton2.isChecked()) {
                textwju.setBackgroundColor(getResources().getColor(R.color.white));
            } else if(radioButton3.isChecked()) {
                textwju.setBackgroundColor(getResources().getColor(R.color.red));
            }

        }
    });

    cancelButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            radioButton1.setChecked(true);

        }
    });
}

And don't forget to remove android:onClick="onRadioClicked" from the radio buttons in the xml.

Answer 3

you can get the option selected by

int radioButtonID = group.getCheckedRadioButtonId();
View radioButton = group.findViewById(radioButtonID);
int radioId = group.indexOfChild(radioButton);
String optionText = 
(RadioButton)group.getChildAt(radioId)).getText().toString();

now you can do what ever you want hope this helps
