按钮 使用匿名内部类 的一些问题

poker_bt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//使用整个包名来跳转
Intent intent=new Intent();
//Intent intent=new Intent(MainActivity.this,poker_game.class);
intent.setClassName(this,"com.example.hackertool.poker_game");
//intent.setClassName(MainActivity.this, "com.example.hackertool.poker_game");

startActivities(intent);

}
});
//为什么失败了？

我是初哥，所以 我觉得是不是 在 this的地方 应该用 Mainactivity.this ?

返回的错误信息是：
