    <p>I created an application which gets multi selected data from 2 tables from sql server. I used 2 edittext to place that data; I am using bundle to get data from 2 activities but I`m not getting the data. My code is:</p> <pre><code>try{ Bundle bn = getIntent().getExtras(); ArrayList&lt;String&gt; data= bn.getStringArrayList("selectedItems"); ArrayList&lt;String&gt; data2= bn.getStringArrayList("selectedItems2"); // String[] resultArr = b.getStringArray("selectedItems"); StringBuilder string = new StringBuilder(); for(int i=0;i&lt;data.size();i++){ string.append(data.get(i).toString()+"\n"); } for(int i=0;i&lt;data2.size();i++){ string2.append(data2.get(i).toString()+"\n"); } area.setText(string2); wwith.setText(string); } catch(Exception e){ e.printStackTrace(); } </code></pre> <p>Can anyone suggest me how to use bundle to get data from multiple activities ?</p> <p>complete code for main Activity</p> <pre><code>public class DcrOpen extends Activity { StringBuilder string=null; StringBuilder string2=null; EditText date,wwith,area; Spinner with; Button save,back,get,get1; String paid5; String dcrdate; MyConnection mycon; String mydate; public void onCreate(Bundle b){ super.onCreate(b); setContentView(R.layout.dcropen); date=(EditText)findViewById(R.id.date); wwith=(EditText)findViewById(R.id.workwith); area=(EditText)findViewById(R.id.area); with=(Spinner)findViewById(R.id.worktype); save=(Button)findViewById(R.id.save); back=(Button)findViewById(R.id.bkdays); get=(Button)findViewById(R.id.get); get1=(Button)findViewById(R.id.get1); mycon=new MyConnection(DcrOpen.this); int paid=MyConnection.PA_ID; try{ Bundle bn = getIntent().getExtras(); ArrayList&lt;String&gt; data= bn.getStringArrayList("selectedItems"); ArrayList&lt;String&gt; data2= bn.getStringArrayList("selectedItems2"); // String[] resultArr = b.getStringArray("selectedItems"); StringBuilder string = new StringBuilder(); for(int i=0;i&lt;data.size();i++){ string.append(data.get(i).toString()+"\n"); } for(int i=0;i&lt;data2.size();i++){ string2.append(data2.get(i).toString()+"\n"); } area.setText(string2); wwith.setText(string); } catch(Exception e){ e.printStackTrace(); } ResultSet rs2; try{ Statement smt=mycon.connection().createStatement(); rs2=smt.executeQuery("DCRDATEDDL "+paid+""); if(rs2.next()==false){ } String mydate3=rs2.getString("DATE_NAME"); date.setText(mydate3); rs2=smt.executeQuery("WORKINGTYPE"); List&lt;String&gt;data1=new ArrayList&lt;String&gt;(); while(rs2.next()){ data1.add(rs2.getString("FIELD_NAME")); } ArrayAdapter&lt;String&gt;dataadapter=new ArrayAdapter&lt;String&gt;(this,android.R.layout.simple_spinner_item,data1); dataadapter.setDropDownViewResource(android.R.layout.simple_list_item_single_choice); with.setAdapter(dataadapter); }catch(Exception e){ } back.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent i=new Intent(getApplicationContext(),DcrMenu.class); startActivity(i); } }); get.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent i=new Intent(getApplicationContext(),ListviewHelper.class); startActivity(i); } }); get1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent in=new Intent(getApplicationContext(),ListviewHelper2.class); startActivity(in); } }); } } </code></pre> <p>Activity ListviewHelper</p> <pre><code>public class ListviewHelper extends Activity implements OnClickListener { Button button; ListView listView; ArrayAdapter&lt;String&gt; adapter; MyConnection mycon; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.data_list); mycon=new MyConnection(ListviewHelper.this); int pa_id=mycon.PA_ID; ResultSet rs; List&lt;String&gt;data=new ArrayList&lt;String&gt;(); try{ Statement smt=mycon.connection().createStatement(); rs=smt.executeQuery("WORKWITH "+pa_id+",'','','','','','',''"); while(rs.next()) { data.add(rs.getString("PA_NAME")); } }catch(Exception e){ e.printStackTrace(); } findViewsById(); adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_multiple_choice, data); listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); listView.setAdapter(adapter); button.setOnClickListener(this); } private void findViewsById() { listView = (ListView) findViewById(R.id.list); button = (Button) findViewById(R.id.testbutton); } public void onClick(View v) { SparseBooleanArray checked = listView.getCheckedItemPositions(); ArrayList&lt;String&gt; selectedItems = new ArrayList&lt;String&gt;(); for (int i = 0; i &lt; checked.size(); i++) { // Item position in adapter int position = checked.keyAt(i); // Add sport if it is checked i.e.) == TRUE!

    1. COYour trend in getting data from bundle is right but can you show us where you put data into your intent?

    3. COBut first of all your need to populate your intent with your data , for example : intent.putExtra("example", example); Then start the intent and inside the create activity you can use your code to get data :)

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).
