onClick里面设置当checkbox.isChecked()默认为true就是选中状态；

xml标签：<CheckBox

        android:id="@+id/fuxuan0"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="确定" />

java：public void dianji0(View v) {

            if (checkBox.isChecked()) {

            mTextView2.setText("被勾选");

            }else {

            mTextView2.setText("未勾选");

        }

    }

checkBox0

                .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                    @Override

                    public void onCheckedChanged(CompoundButton buttonView,

                            boolean isChecked) {

                        if (isChecked) {

                            Toast.makeText(MainActivity.this, "听音乐", 1).show();

                        }

                    }

                });
