Question

I want to pass a string from 1 activity to another, although I have taken reference from many accepted answers from other threads, I am facing problem that I am not able to debug. When I comment extras.putString as shown in code below, Toast message shows the correct address which means value is being set properly and code works fine but when I use extras.putString(), I get NullPointerException and application closes due to exception. There are many characters in my address string. Infact even if I use extras.putString("userAddress", "test") I get NullPointerException

在此,我的主要活动是我所说的“FBShare活动”:

Intent mIntent = new Intent(this, FBShare.class);   
Bundle extras = mIntent.getExtras();
String currentAddress = getCurrentAddress(ourLocation);
Toast.makeText(getBaseContext(), getCurrentAddress(ourLocation), Toast.LENGTH_SHORT).show();
extras.putString("userAddress", currentAddress);
startActivity(mIntent);

And in FBShare Activities 我试图 follows取以下价值观:

strAddress = getIntent().getExtras().getString("userAddress");

这里指的是正在做类似事情的一条路。

Answer 1

尝试我的法典

Intent mIntent = new Intent(this, FBShare.class);   
Bundle extras = new Bundle();
String currentAddress = getCurrentAddress(ourLocation);
Toast.makeText(getBaseContext(), getCurrentAddress(ourLocation), Toast.LENGTH_SHORT).show();
extras.putString("userAddress", currentAddress);
mIntent.putExtras(extras);
startActivity(mIntent);

hope this will work.

Answer 2

直接对意图进行补充:

mIntent.putExtra ("Key”,“Value”

另外,你还利用额外资金提取了这笔钱。

Intene t = getIntent();
String k="key";
if (t.hasExtra(k)) {
  s = t.getStringExtra(k);
  ...
}

很多种类的劳动力得到/投入

Answer 3

Intent mIntent = new Intent(this, FBShare.class);   
String currentAddress = getCurrentAddress(ourLocation);
Toast.makeText(getBaseContext(), getCurrentAddress(ourLocation), Toast.LENGTH_SHORT).show();
mIntent.putString("userAddress", currentAddress);
startActivity(mIntent);

就你而言,没有必要布局,因为你似乎只是用上面的法典来形容你。
