Android---2.0中调用subActivity时数据传送

Android---2.0与之前的1.6中的数据传送方式不太一样。最大区别：

1.6

protected void onActivityResult(int requestCode, int resultCode, String data, Bundle extras)
 { /* Place out code to react on Activity-Result here. */ 
super.onActivityResult(requestCode, resultCode, data, extras); 
}
MySecondActivity.this.setResult(1, keyword);

 2.0

protected void onActivityResult(int requestCode, int resultCode, Intent i)
	{
		super.onActivityResult(requestCode, resultCode, i);
		
	}

 应该说2.0中将data以及extras都放进了intent，封装的更好了.使用中注意即可.

//传送时
Intent data = new Intent();
				data.putExtra("Data", search.getText().toString());
				subActivityWithResult.this.getIntent().putExtra("Data",
						search.getText().toString());
				subActivityWithResult.this.setResult(SUCCESS_RETURN_CODE, data);
				subActivityWithResult.this.finish();
//接收时
protected void onActivityResult(int requestCode, int resultCode, Intent i)
	{
		super.onActivityResult(requestCode, resultCode, i);
		if(requestCode==SUB_ACTIVITY_REQUEST_CODE)
		{
			
			
			data=i.getExtras().getString("Data"));

		}
	}

我汗，找了半天没找到subActivityWithResult这个方法……
难道是我SDK配置有问题……回去看看去……
