android studio 跳转传值

<Button
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="点击跳转"
 android:layout_alignLeft="@+id/tv_title"
 android:layout_marginLeft="90dp"
 android:id="@+id/button"
 android:onClick="skip"
 />

传值写法

public void skip(View view){
    Intent intent = new Intent();
    intent.setClass(MainActivity.this,SecondActivity.class);
    Bundle bundle=new Bundle();
    bundle.putString("id","完美二号");
    intent.putExtras(bundle);
    startActivity(intent);
}

跳转之后的界面

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical" android:layout_width="match_parent"
 android:layout_height="match_parent"
 >

    <TextView
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="测试"
 android:id="@+id/ceshi"
 />

</LinearLayout>

如何得到参数中得值
private String type="";
final Intent intent = getIntent();
@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);
    Bundle bundle = this.getIntent().getExtras();
    type=bundle.getString("id");
    TextView textView=(TextView) findViewById(R.id.ceshi);
    textView.setText(type);
