可能重复：   How从一个活动将值传递给另一个机器人？

我有一个标题（从ApiDemos list6例子）名单，他们的尸体（内容）的活动。我有一个活动，在这里我想补充的说明。当我点击添加按钮，我希望我的笔记的标题出现在列表中。同样的，身体。问题是，在名单的活动有两个String []数组与predefined硬codeD标题和机构。我应该怎么做才能够与内容，而无需这些硬件codeD值添加自己的新游戏？ 我知道我必须使用意图与startActivityForResult，但是这可能是我所知道的......

I have an activity with a list of titles and their bodies(content) (list6 example from ApiDemos). And I have an activity, where I add a note. When I click on "Add" button, I want the title of my note to appear on the list. Same with body. The problem is, that in List activity there are two String[] arrays with predefined hard-coded titles and bodies. What should I do to be able to add my own new titles with a content instead of having these hard-coded values? I know I must use intents with startActivityForResult, but that's probably all I know...

推荐答案

您有两个选项：

此方式，可以使用它的情况相同，从与添加按钮的活动，并修改列表视图为：

This way you can use the same instances of it from the activity with add button and modify the listview as:

FirstActivity.listTitlesArrayList.add(listTitleString);
FirstActivity.listDescriptionArraylist.add(listDescriptionString);//this is probably your note
FirstActivity.listView.invalidateViews();

2），如果你想使用意图：

而要去ListActivity通数据通过。

2)if you want to use intents:

while going to the ListActivity pass data by..

intent.putExtra("Title", listTitleString);
intent.putExtra("Content", listDescriptionString);
startActivity(intent);

和恢复它的第二个活动使用的：

and to recover it in second activity use:

title= getIntent().getExtras().getString("Title");

...等..

...and so on..
