Honestly I did somesearch about this before asking. how to receive intent from activity to fragmentactivity
I am trying to use viewpager. I am having error here in get argumentsBundle extras = getArguments();
public class SingleViewActivity extends FragmentActivity {
ImageView imageView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page_view);
ArrayList<Listitem> personArrayList = new ArrayList<Listitem>();
// Listitem item = new Listitem("1", "http://developer.android.com/assets/images/android_logo.png");//I used to add it staticly
Bundle extras = getArguments();
if (extras != null) {
extras = extras.getParcelableArrayList(ARG_PERSON_LIST);
personArrayList.add(item); }
// DemoObjectFragment f = DemoObjectFragment.newInstance(personArrayList);
ViewPager mViewPager = (ViewPager) findViewById(R.id.pager);
Log.d("s", "singleview");
DemoCollectionPagerAdapter mDemoCollectionPagerAdapter = new DemoCollectionPagerAdapter( getSupportFragmentManager(),personArrayList);
mViewPager.setAdapter(mDemoCollectionPagerAdapter);
You are going to need two Activities. Since you didn't post the Activity
that starts the posted Activity
, I have made a simple one that contains only a Button
that starts the shown Activity
.
Take note of the commented steps. There are six steps total.
The first Activity
gets the ArrayList
data, the passes it to the second Activity
, which in turn gives in to the DemoCollectionAdapter
.
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Step 1: Build an ArrayList to pass to the next Activity
ArrayList<Listitem> items = new ArrayList<Listitem>();
items.add(new Listitem("1", "http://developer.android.com/assets/images/android_logo.png"));
items.add(new Listitem("2", "https://i.stack.imgur.com/B28Ca.jpg?s=328&g=1"));
// Step 2: Create an Intent to start the next Activity
Intent intent = new Intent(getApplicationContext(), SingleViewActivity.class);
// Step 3: Put the ArrayList into the Intent
intent.putParcelableArrayListExtra(SingleViewActivity.ARG_PERSON_LIST, items);
// Step 4: Start the next Activity
startActivity(intent);
}
});
}
}
public class SingleViewActivity extends FragmentActivity {
public static final String ARG_PERSON_LIST = "ARG_PERSON_LIST";
private ArrayList<Listitem> items;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page_view);
// Step 5: Get the Bundle from the Intent that started this Activity
Bundle extras = getIntent().getExtras();
if (extras != null) {
// Step 6: Get the data out of the Bundle
items = extras.getParcelableArrayList(ARG_PERSON_LIST);
} else {
items = new ArrayList<Listitem>();
}
ViewPager pager = (ViewPager) findViewById(R.id.pager);
DemoCollectionPagerAdapter adapter = new DemoCollectionPagerAdapter(getSupportFragmentManager(), items);
pager.setAdapter(adapter);
}
}
