    <p>From the given <code>ListView</code> in picture, I select the contact to send sms and move to another activity (second picture). And from this sms <code>Activity</code> picture. When I press back hardware button available on phone, I should move where I want. I don't want a default <code>Activity</code> to be displayed. How can I do this?</p> <p><img src="https://i.stack.imgur.com/YEnnQ.png" alt=""> <img src="https://i.stack.imgur.com/dL5QV.png" alt=""></p> <pre><code>public class SendSms extends Activity{ ListView listView; List&lt;RowItems&gt; rowItems; CustomListViewAdapter adapter; String toNumbers = ""; String separator; int i=0,j,count=0,count1; String a[]=new String[5]; String number,val2; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.new4); listView = (ListView) findViewById(R.id.list); rowItems = new ArrayList&lt;RowItems&gt;(); val2=getIntent().getStringExtra("name"); ContentResolver cr = getContentResolver(); Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); if (cur.getCount() &gt; 0) { while (cur.moveToNext()) { String rawContactId = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); Cursor c = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER, // ContactsContract.CommonDataKinds.Phone.TYPE, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.PHOTO_ID }, ContactsContract.Data.RAW_CONTACT_ID + "=?", new String[] { rawContactId }, null); if (c != null) { if (c.moveToFirst()) { String number = c.getString(0); //int type = c.getInt(1); String name = c.getString(1); int photoId = c.getInt(2); Bitmap bitmap = queryContactImage(photoId); RowItems p=new RowItems(bitmap, number, name); rowItems.add(p); } adapter = new CustomListViewAdapter(this, R.layout.new5, rowItems); listView.setAdapter(adapter); c.close(); } } } } private Bitmap queryContactImage(int imageDataRow) { Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI, new String[] { ContactsContract.CommonDataKinds.Photo.PHOTO }, ContactsContract.Data._ID + "=?", new String[] { Integer.toString(imageDataRow) }, null); byte[] imageBytes = null; if (c != null) { if (c.moveToFirst()) { imageBytes = c.getBlob(0); } c.close(); } if (imageBytes != null) { return BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length); } else { return null; } } public void showResult(View v) { // String result = ""; String result1=""; for (RowItems p : adapter.getBox()) { if (p.chck){ // result += "\n" + p.getTitle(); result1 +="\n" +p.getDesc(); a[i]=p.getTitle(); i++; count++; } count1=count; } Toast.makeText(this, result1+"\n", Toast.LENGTH_LONG).show(); } public void send(View v) throws IOException { int value=a.length-count1; for(j=0;j&lt;a.length-value;j++){ if(android.os.Build.MANUFACTURER.equalsIgnoreCase("Samsung")){ separator = ","; } else separator = ";"; number = a[j]; toNumbers= toNumbers +number +separator; } toNumbers = toNumbers.substring(0, toNumbers.length()); Uri sendSmsTo = Uri.parse("smsto:" + toNumbers); String smsValue = "help iam in danger..i am presently at \n"+val2; if(val2==null){ Toast.makeText(SendSms.this, "wait.....", Toast.LENGTH_LONG).show(); } Intent intent = new Intent(Intent.ACTION_VIEW); intent.setType("vnd.android-dir/mms-sms"); intent.putExtra("sms_body", smsValue); intent.setData(sendSmsTo); startActivity(intent); } </code></pre>

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.

SQuiL has stopped working due to an internal error.

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