我正在执行一个复选框活动，它将复选框状态保存并具有用于重置所有复选框的按钮。重置Android中的所有复选框
我被困在如何取消选中所有选中的复选框。 我已经找到了关于如何做的代码，但是当我点击按钮时没有发生任何事情。我试图首先做1复选框，但没有成功。我做错什么了吗？
我试图做的未经检查的代码是低于所有的代码。
这里是我的代码：
public class PreDiveBK extends Activity implements CompoundButton.OnCheckedChangeListener {
Button btn;
CheckBox cb1, cb2, cb3, cb4, cb5, cb6, cb7, cb8, cb9, cb10, cb11, cb12, cb13,
cb14, cb15, cb16, cb17, cb18, cb19, cb20, cb21, cb22, cb23, cb24;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.predbk);
cb1 = (CheckBox) findViewById(R.id.cb1);
cb1.setChecked(getFromSP("cb1"));
cb1.setOnCheckedChangeListener(this);
cb2 = (CheckBox) findViewById(R.id.cb2);
cb2.setChecked(getFromSP("cb2"));
cb2.setOnCheckedChangeListener(this);
