4.startActivity(it);
5.//where pkg_name is the full package path for an application

7.//显示指定应用的详细页面（这个好像不支持了，找不到app_id）
8.Uri uri = Uri.parse("market://details?id=app_id");
9.Intent it = new Intent(Intent.ACTION_VIEW, uri);
10.startActivity(it);

Activity 的切换
2个Activity 的切换,没有数据传递
//从A到B
Intent intent = new Intent();
intent.setClass(A.this, B.class);
startActivity(intent);

2个Activity 之间传递数据
相关的几个函数
startActivityForResult

public final void setResult(int resultCode, String data)
回调函数

protected void onActivityResult(int requestCode, int resultCode, Intent data)

例如A到B,从B得到数据
//A到B
static final int RG_REQUEST = 0;
Intent intent = new Intent();
intent.setClass(A.this, B.class);
startActivityForResult(intent,RG_REQUEST);
                                  
//在B中处理
Bundle bundle = new Bundle();
bundle.putString("DataKey", edittext.getText().toString());//给bundle 写入数据
Intent mIntent = new Intent();
mIntent.putExtras(bundle);
setResult(RESULT_OK, mIntent);
finish();

//最后在A的回调函数里面接收数据
if (requestCode == RG_REQUEST) {
   if (resultCode == RESULT_CANCELED)
      setTitle("Canceled...");
   else if(resultCode == RESULT_OK) {
     setTitle((String)data.getCharSequenceExtra("DataKey"));
    }
}
