如何将数据从一个片段传递到另一个片段？

Question

startActivity(new Intent(SecondScreen.this,FragmentOne.class).
putExtra("key", VideoFullUrl)); 

在FragmentOne.class中扩展了android.support.v4.app.Fragment

      public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    String   url = getIntent().getStringExtra("key");//here showing compilation error "cannot resolve method getIntent "
   //somecode....

Answer 1

Fragment to Fragment set and get Argument：

开始活动：

 int friendId = 2; //value to pass as extra 
 i = new Intent(firstActivity, SecondActivity.class);
 i.putExtra("friendsID", friendId);
 firstActivity.startActivity(i);

SecondActivity：

 Fragment_A mFragment_A = new Fragment_A();
 mFragment_A.setArguments(getIntent().getExtras());

Fragment_A：

Bundle bundle = new Bundle();
String Item = getArguments().getString("friendsID");
bundle.putInt("friendsID", Integer.parseInt(Item));

// code

Fragment_B mFragment_B = new Fragment_B();
mFragment_B.setArguments(bundle);

Fragment_B：

Bundle bundle = getArguments();
int value = bundle.getInt("friendsID");

Log.e("value Fragment get Argument ", "friendsID :" + value);

这项工作对我来说，试试这可能是这个样本帮助你。
