推荐答案

实施的ListView 的OnItemClickListener，一旦你处理此事件，试图让该行的位置被点击。

Implement ListView's OnItemClickListener, once you handle this event, try to get the location of the row that was clicked.

一旦你得到它，访问源阵列（或者其他任何你有），特别是行的位置。这样一来，你就必须要传递到另一个活动的数据。

Once you get it, access that particular row position in the source array (or whatever else you're having). This way, you'll have the data that you want to pass to another activity.

现在使用code：

Intent anotherActivityIntent = new Intent(this, AnotherActivity.class);
anotherActivityIntent.putExtra("my.package.dataToPass",dataFromClickedRow);
startActivity(anotherActivityIntent);

当 anotherActivityIntent 启动 AnotherActivity 类，使用下面的code访问的价值，你通过了：

and when the anotherActivityIntent starts the AnotherActivity class, use following code to access the value that you had passed:

Bundle recdData = getIntent().getExtras();
String myVal = recdData.getString("my.package.dataToPass");

现在你在设为myVal 可变数据。你可以使用任何其他数据类型，无论你喜欢。

Now you have your data in myVal variable. you can use any other data type, whichever you like.
