Api demo源码学习（5）App/Activity/Forwarding Activity跳转

这一节也非常简单，显示了一下Activity跳转的实现，直接上代码。

View Code

 1 public class Forwarding extends Activity
 2 {
 3     @Override
 4        protected void onCreate(Bundle savedInstanceState)
 5     {
 6         super.onCreate(savedInstanceState);
 7 
 8         setContentView(R.layout.forwarding);
 9 
10         // 设置Button监听事件，点击Button后，跳转到其他Activity，点返回按钮后不会再回到本Activity
11         Button goButton = (Button)findViewById(R.id.go);
12         goButton.setOnClickListener(mGoListener);
13     }
14 
15     private OnClickListener mGoListener = new OnClickListener()
16     {
17         public void onClick(View v)
18         {
19             // Here we start the next activity, and then call finish()
20 // so that our own will stop running and be removed from the
21 // history stack.
22 //Activity跳转即new出一个Intent，通过startActivity实现跳转，最后用finish()函数结束本Activity的生命周期
23             Intent intent = new Intent();
24             intent.setClass(Forwarding.this, ForwardTarget.class);
25             startActivity(intent);
26             finish();
27         }
28     };
29 }

最后也别忘了再AndroidManifest.xml中注册一下跳转后的Activity。

以上即可。
