Answer 1

一旦此视图为CompoundButton（link），强烈建议使用setOnCheckedChangeListener打开（选中）或关闭（取消选中）：

    switch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(ischecked){
      //do something if is checked
    }else{
     //do something if is unchecked
    }
}

}）;

private boolean serviceEnable = false;

    public boolean isServiceEnable() {
        return serviceEnable;
    }

    public void setServiceEnable(boolean serviceEnable) {
        this.serviceEnable = serviceEnable;
    }

    private void savePreference() {
        SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(this).edit();
        editor.putBoolean("service", isServiceEnable());
        editor.commit();
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.checked_textview);

        final CheckedTextView cc = (CheckedTextView) findViewById(R.id.check_text_view);
        cc.setChecked(isServiceEnable());

        cc.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                setServiceEnable(!isServiceEnable());
                cc.setChecked(isServiceEnable());
                savePreference();
            }
        });
    }
