How to uncheck radio button in android programmatically code example

Example 1: how to check and uncheck single radio button in android

I have made a solution for it using set selected attribute of the radio button.

final RadioButton radioButton = findViewById(R.id.radioButton);
        radioButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (!radioButton.isSelected()) {
                    radioButton.setChecked(true);
                    radioButton.setSelected(true);
                } else {
                    radioButton.setChecked(false);
                    radioButton.setSelected(false);
                }
            }
        });

Example 2: how to set radio button checked in android programmatically

In your layout you can add android:checked="true" to CheckBox you want to be selected.

Or programmatically, you can use the setChecked method defined in the checkable interface:

RadioButton b = (RadioButton) findViewById(R.id.option1);
b.setChecked(true);
