    <p>I have two fragments(A &amp; B). In fragment A, I have two edit boxes and a search button.</p> <p>Upon click of search button, I am populating a list view with searched results below the button. On list item click, I am passing values using bundle to fragment B using below code:</p> <pre><code>FragmentB details = new FragmentB(); Bundle detailsBundle = new Bundle(); detailsBundle.putString("ProdCode", _prodCode); detailsBundle.putString("ProdName", _prodName); detailsBundle.putString("UnitPrice", _unitPrice); detailsBundle.putString("StockValue", _stockValue); detailsBundle.putString("Indicator", _indicator); detailsBundle.putString("OpenOrderValue", _openOrderValue); detailsBundle.putString("OpenInvoiceValue", _openInvoiceValue); details.setArguments(detailsBundle); FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.replace(R.id.container, details, "Details"); ft.addToBackStack(null); ft.commit(); </code></pre> <p>But when I click back button on Fragment B, populated list in fragment A getting disappeared. How can I preserve the searched results in listview and also how can I clear the text from the edit boxes on coming back from fragment B to fragment A.</p> <p>[Edit]</p> <pre><code>public class MainActivity extends Activity implements OnClickListener { private Button button1, button2, button3, button4; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.main_activity); button1 = (Button) findViewById(R.id.btnFrgament1); button2 = (Button) findViewById(R.id.btnFrgament2); button3 = (Button) findViewById(R.id.btnFrgament3); button4 = (Button) findViewById(R.id.btnFrgament4); FragmentManager fm = getFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); FirstFragment initialFragment = new FirstFragment(); ft.add(R.id.containerLinearLayout, initialFragment); ft.commit(); button1.setOnClickListener(this); button2.setOnClickListener(this); button3.setOnClickListener(this); button4.setOnClickListener(this); } @Override public void onClick(View v) { Fragment newFragment; int id = v.getId(); switch(id) { case R.id.btnFragment1: newFragment = new FirstFragment(); break; case R.id.btnFragment2: newFragment = new SecondFragment(); break; case R.id.btnFragment3: newFragment = new ThirdFragment(); break; case R.id.btnFragment4: newFragment = new FourthFragment(); break; default: newFragment = new FirstFragment(); break; } FragmentTransaction transaction = getFragmentManager().beginTransaction(); transaction.replace(R.id.containerLinearLayout, newFragment); transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); transaction.commit(); } </code></pre> <p>SecondFragment has two edit boxes and a button(Search). I am displaying searched results in listview below button. When I click on list item, I am passing details to next fragment using the bundle as shown above. When I come back by hitting back button from details fragment to previous fragment, list getting disappeared.</p>

    1. CONot sure so leaving it as a comment. 1) In A have the EditText's as field variables and do setRatainInstance(true) in onCreate. This should (I think) keep whatever values you store (unless ofcourse you instansiate an entirely new fragment when adding A). 2) you could just use setText("") on the EditTexts in B whenever you move back, or alternatively in onCreateViews

    2. COHow is your Fragment A implementation? I will answer you because I think I know what's wrong, but to be sure I need the implementation.

    3. CO@RenanBandeira I have divided my activity into two fragments. On left side I have 4 buttons. Upon click on button, I am opening respective fragment on right side. I have posted my code. Please check. Now in right side, I have two edit boxes and a button(Search). I am displaying searched results in a listview below the button. On list item click I am passing details to next fragment using bundle as shown in my query. When I come back from details fragment to previous fragment, list is getting disappeared.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
