Getting Arguments From A Bundle

I'm trying to pass arguments from my Activity to a Fragment and I'm using this code: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(sav

Solution 1:

The best way to use arguments with your fragment is to use the newInstance function of the fragment.Create a static method that gets your params and pass them in the fragment through the new instance function as below:

publicstatic myFragment newInstance(String param1, String param2) {
    myFragment fragment = new myFragment ();
    Bundle args = newBundle();
    args.putString(ARG_PARAM1, param1);
    args.putString(ARG_PARAM2, param2);
    fragment.setArguments(args);
    return fragment;
}

And then on create set your global arguments:

@OverridepublicvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_PARAM1);
        mParam2 = getArguments().getString(ARG_PARAM2);
    }
}

on your main activity you will create the fragment like

myFragment__myFragment= myFragment.newInstance("test","test");

That should work

Solution 2:

This is a correct approach

Send (in the Activity):

finalFragmentTransactionft= getSupportFragmentManager().beginTransaction();

finalDetailActivityFragmentfrg=newDetailActivityFragment ();
ft.replace(R.id.container, frg);

finalBundlebdl=newBundle();
bdl.putString("yourKey", "Some Value");
frg.setArguments(bdl);

ft.commit();

Receive (in the Fragment):

finalBundlebdl= getArguments();

Stringstr="";
try
{
    str = bdl.getString("yourKey");
}
catch(final Exception e)
{
    // Do nothing
}
