private OnClickListener onClickListener = new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            // TODO Auto-generated method stub
            SharedPreferences prec = MainActivity.this.getSharedPreferences("kuka", Context.MODE_PRIVATE);
            switch (v.getId())
            {
            case R.id.btnSave: // 保存数据
                Editor editor = prec.edit();
                editor.putString("name", editName.getText().toString());
                editor.putInt("age", Integer.valueOf(editAge.getText().toString()));

                editor.commit();
                Toast.makeText(MainActivity.this, "保存成功", Toast.LENGTH_LONG).show();
                break;

            case R.id.btnShow: // 取出数据
                String name = prec.getString("name", "no");
                int age = prec.getInt("age", 0);
                txtResul.setText("name:" + name + ",age:" + age);
