Listview to the same activity with different text on tabbed activity
I'm new at Android programming and I need your help. Please. What I want to do.
I created listview, from listview I created OnItemClickListener to TabbedActivity.
Now I want for each listview item to show different text on TabbedActivity.
This is MainActivity:
public class MainActivity extends AppCompatActivity {
Toolbar toolbar;
ListView listview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle(getResources().getString(R.string.app_name));
listview = (ListView) findViewById(R.id.listview);
ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, getResources().getStringArray(R.array.bolesti));
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
switch (i){
case 0:
Intent intent = new Intent(MainActivity.this, TabbedActivity.class);
startActivity(intent);
break;
case 1:
Intent intent1 = new Intent(MainActivity.this, TabbedActivity.class);
startActivity(intent1);
break;
}
}
});
listview.setAdapter(mAdapter);
}}
TabbedActivity:
public class TabbedActivity extends AppCompatActivity {
/**
* The {@link android.support.v4.view.PagerAdapter} that will provide
* fragments for each of the sections. We use a
* {@link FragmentPagerAdapter} derivative, which will keep every
* loaded fragment in memory. If this becomes too memory intensive, it
* may be best to switch to a
* {@link android.support.v4.app.FragmentStatePagerAdapter}.
*/
private SectionsPagerAdapter mSectionsPagerAdapter;
/**
* The {@link ViewPager} that will host the section contents.
*/
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tabbed);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_tabbed, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
/**
* The fragment argument representing the section number for this
* fragment.
*/
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
/**
* Returns a new instance of this fragment for the given section
* number.
*/
public static PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_tabbed, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.section_label);
textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
return rootView;
}
}
/**
* A {@link FragmentPagerAdapter} that returns a fragment corresponding to
* one of the sections/tabs/pages.
*/
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a PlaceholderFragment (defined as a static inner class below).
switch (position){
case 0:
Tab1Opis tab1 = new Tab1Opis();
return tab1;
case 1:
Tab2Simptomi tab2 = new Tab2Simptomi();
return tab2;
case 2:
Tab3Uzroci tab3 = new Tab3Uzroci();
return tab3;
case 3:
Tab4Lijecenje tab4 = new Tab4Lijecenje();
return tab4;
default:
return null;
}
}
@Override
public int getCount() {
// Show 3 total pages.
return 4;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Opis";
case 1:
return "Simptomi";
case 2:
return "Uzroci";
case 3:
return "Lijecenje";
}
return null;
}
}}
TabbedActivity contains 4 tabs, all of them have different .java class example:
public class Tab2Simptomi extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_simptomi, container, false);
return rootView;
}}
I need to change text in every fragment when I click on different listview item.
Can you help me? Thank you.
Check the pictures. Thank you a lot.
Solution
You can pass text from your MainActivity to TabbedActivity fragment Tab2Simptomi as below:
1. Pass text from MainActivity to TabbedActivity, using Intent extras.
Update onItemClick() as below:
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
switch (i){
case 0:
Intent intent = new Intent(MainActivity.this, TabbedActivity.class);
intent.putExtra("YOUR_TEXT", "Text One");
startActivity(intent);
break;
case 1:
Intent intent1 = new Intent(MainActivity.this, TabbedActivity.class);
intent1.putExtra("YOUR_TEXT", "Text Two");
startActivity(intent1);
break;
}
}
});
2. Pass text from TabbedActivity to Tab2Simptomi, setting bundle as arguments of fragments inside SectionsPagerAdapter.
In TabbedActivity onCreate() method, get text that was passed from MainActivity
public class TabbedActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tabbed);
// Get text
String text = getIntent().getStringExtra("YOUR_TEXT");
// Pass text to SectionsPagerAdapter
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager(), text);
.............
......................
}
}
Update SectionsPagerAdapter to pass text to Fragments:
public class SectionsPagerAdapter extends FragmentPagerAdapter {
private String yourText;
public SectionsPagerAdapter(FragmentManager fm, String yourText) {
super(fm);
this.yourText = yourText;
}
@Override
public Fragment getItem(int position) {
Bundle bundle = new Bundle();
bundle.putString("YOUR_TEXT", yourText);
switch (position){
case 0:
Tab1Opis tab1 = new Tab1Opis();
tab1.setArguments(bundle); // Pass text to Tab1Opis fragment
return tab1;
case 1:
Tab2Simptomi tab2 = new Tab2Simptomi();
tab2.setArguments(bundle);
return tab2;
case 2:
Tab3Uzroci tab3 = new Tab3Uzroci();
tab3.setArguments(bundle);
return tab3;
case 3:
Tab4Lijecenje tab4 = new Tab4Lijecenje();
tab4.setArguments(bundle);
return tab4;
default:
return null;
}
}
@Override
public int getCount() {
// Show 3 total pages.
return 4;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Opis";
case 1:
return "Simptomi";
case 2:
return "Uzroci";
case 3:
return "Lijecenje";
}
return null;
}
}}
3. Finally get text from individual Frgament and do whatever you want.
Update Tab2Simptomi as below:
public class Tab2Simptomi extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_simptomi, container, false);
String finalText = getArguments().getString("YOUR_TEXT");
// Do something with finalText
Toast.makeText(getActivity(), "Final Text: " + finalText, Toast.LENGTH_SHORT).show();
return rootView;
}
}
UPDATE:
Assuming your fragment texts are static.
1. Pass texts from MainActivity to TabbedActivity, using Intent extras.
Update onItemClick() as below:
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
switch (i){
case 0:
Intent intent = new Intent(MainActivity.this, TabbedActivity.class);
intent.putExtra("OPIS", "Item1 :: Text for Fragment OPIS");
intent.putExtra("SIMPTOMI", "Item1 :: Text for Fragment SIMPTOMI");
intent.putExtra("UZROCI", "Item1 :: Text for Fragment UZROCI");
intent.putExtra("LIJECENJE", "Item1 :: Text for Fragment LIJECENJE");
startActivity(intent);
break;
case 1:
Intent intent1 = new Intent(MainActivity.this, TabbedActivity.class);
intent1.putExtra("OPIS", "Item2 :: Text for Fragment OPIS");
intent1.putExtra("SIMPTOMI", "Item2 :: Text for Fragment SIMPTOMI");
intent1.putExtra("UZROCI", "Item2 :: Text for Fragment UZROCI");
intent1.putExtra("LIJECENJE", "Item2 :: Text for Fragment LIJECENJE");
startActivity(intent1);
break;
}
}
});
2. Pass texts from TabbedActivity to Tab2Simptomi, setting bundle as arguments of fragments inside SectionsPagerAdapter.
In TabbedActivity onCreate() method, get text that was passed from MainActivity
public class TabbedActivity extends AppCompatActivity {
ArrayList<String> stringArray;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tabbed);
stringArray = new ArrayList<String>();
// Get texts
String textOPIS = getIntent().getStringExtra("OPIS");
String textSIMPTOMI = getIntent().getStringExtra("SIMPTOMI");
String textUZROCI = getIntent().getStringExtra("UZROCI");
String textLIJECENJE = getIntent().getStringExtra("LIJECENJE");
// Add text to ArrayList
stringArray.add(textOPIS);
stringArray.add(textSIMPTOMI);
stringArray.add(textUZROCI);
stringArray.add(textLIJECENJE);
// Pass ArrayList to SectionsPagerAdapter
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager(), stringArray);
.............
......................
}
}
Update SectionsPagerAdapter to pass text to Fragments:
public class SectionsPagerAdapter extends FragmentPagerAdapter {
private ArrayList<String> stringList;
public SectionsPagerAdapter(FragmentManager fm, ArrayList<String> stringArray) {
super(fm);
this.stringList = stringArray;
}
@Override
public Fragment getItem(int position) {
Bundle bundle = new Bundle();
bundle.putString("YOUR_TEXT", stringList.get(position)); // Get string from stringList using position
switch (position){
case 0:
Tab1Opis tab1 = new Tab1Opis();
tab1.setArguments(bundle); // Pass text to Tab1Opis fragment
return tab1;
case 1:
Tab2Simptomi tab2 = new Tab2Simptomi();
tab2.setArguments(bundle);
return tab2;
case 2:
Tab3Uzroci tab3 = new Tab3Uzroci();
tab3.setArguments(bundle);
return tab3;
case 3:
Tab4Lijecenje tab4 = new Tab4Lijecenje();
tab4.setArguments(bundle);
return tab4;
default:
return null;
}
}
@Override
public int getCount() {
// Show 3 total pages.
return 4;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Opis";
case 1:
return "Simptomi";
case 2:
return "Uzroci";
case 3:
return "Lijecenje";
}
return null;
}
}}
3. Finally get text from individual Frgament and do whatever you want.
Update Tab2Simptomi as below:
public class Tab2Simptomi extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_simptomi, container, false);
String finalText = getArguments().getString("YOUR_TEXT");
// Do something with finalText
TextView yourTextView = (TextView) rootView.findViewById(R.id.your_textview);
// Show text on TextView
yourTextView.setText(finalText);
Toast.makeText(getActivity(), "Final Text: " + finalText, Toast.LENGTH_SHORT).show();
return rootView;
}
}
Hope this will help~
