我在第一个活动中有两个活动，我有两个文本视图fromLocation和toLocation。点击进出文本视图我正在调用下一个活动，其中我有一个地图，我选择了一个存储在字符串中并在文本视图中显示的位置。这个选择位置我要在第一个活动的位置文本视图上显示onClick在第二个活动中的useLocation布局，根据选择的文本视图。如果onClick of fromLocation，则地址应显示在fromLocation文本视图中，onClick toLocation地址应显示在toLocation上。这将是onResume方法的第一个活动。
现在，当我第一次选择地址时，我会在两个文本视图中获取地址onClick onLocation text view。
如何做到这一点..？

答案 0 :(得分：0)
如果我理解正确..您应该以{{1}}启动第二个活动，然后在地图上选择位置后返回结果。
现在，第一个活动应该是方法startActivityForResult
http://developer.android.com/training/basics/intents/result.html
onActivityResult完成，您存储所选位置setResult中获取结果并将其设置为textView 第二个textview也一样。对不同的textview使用不同的请求代码，您应该在onActivityResult中检查以确定在第二个活动中选择了哪个textView数据
