getIntent不知道key获取value

不废话，上代码

MainActivity.java 跳转代码

Intent intent = new Intent(MainActivity.this, IntentActivity.class);
intent.putExtra("name", "zhaotf");
intent.putExtra("age", 110);
startActivity(intent);

IntentActivity.java获取值代码

Intent intent = getIntent();
Bundle bundle = intent.getExtras();
Set<String> set = bundle.keySet();
for (Iterator iterator = set.iterator(); iterator.hasNext();) {
	String key = (String) iterator.next();
	Object value = bundle.get(key);
	Log.i("IntentActivity", "key:" + key + " value:" + value);
}

结果
