如何打开和关闭单个菜单按钮？

Question

我想在菜单中设置一个普通按钮，作为一个开关按钮，如切换按钮。但我不确定如何让一个按钮像开关一样？

switch(item.getItemId()){
    case R.id.switcher:

        View view = this.getWindow().getDecorView();
        view.setBackgroundColor(Color.parseColor("#80FFFFFF"));

                 //I want to change the color of the background by clicking once
                  //and set the background color back to normal. How will I achieve this ?
    return true;

试试这个：

@Override
public void onClick(View v) {
    if ((v.getId() == R.id.my_button){
        buttonOnClick(v);
    }
}

private void buttonOnClick(View v) {
    switch (v.getId()) {
    case R.id.my_button: {
    if (v.isSelected()) {
        // is selected, deselect!
        v.setSelected(false);
        //do your staff here
    } else {
        // is not selected, select!
        v.setSelected(true);
        //do your staff here
    }
    break;
    }
    default:
        break;
}
