Android Intent的幾個主要用法

1. 啟動一個新的Activity

1. Intent it = new Intent(Activity.Main.this, Activity2.class);
2. startActivity(it);

2. 向下一個Activity傳遞資料（使用Bundle和Intent.putExtras）

1. Intent it = new Intent(Activity.Main.this, Activity2.class);
2. Bundle bundle=new Bundle();
3. bundle.putString("name", "This is from MainActivity!");
4. it.putExtras(bundle);      // it.putExtra(“test”, "shuju”);
5. startActivity(it);            // startActivityForResult(it,REQUEST_CODE);

對於資料 的擷取可以採用：

1. Bundle bundle=getIntent().getExtras();
2. String name=bundle.getString("name");

3. 向上一個Activity返回結果（使用setResult，針對startActivityForResult(it,REQUEST_CODE)啟動 的Activity）

1.         Intent intent=getIntent();
2.         Bundle bundle2=new Bundle();
3.         bundle2.putString("name", "This is from ShowMsg!");
4.         intent.putExtras(bundle2);
5.         setResult(RESULT_OK, intent);

4. 回調上一個Activity的結果處理函數（onActivityResult）

1. @Override
2.     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
3.         // TODO Auto-generated method stub
4.         super.onActivityResult(requestCode, resultCode, data);
5.         if (requestCode==REQUEST_CODE){
6.             if(resultCode==RESULT_CANCELED)
7.                   setTitle("cancle");
8.             else if (resultCode==RESULT_OK) {
9.                 String temp=null;
10.                 Bundle bundle=data.getExtras();
11.                 if(bundle!=null)  temp=bundle.getString("name");
12.                 setTitle(temp);
13.             }
14.         }
15.     }
