    <p>I am designing a form containing fields and wrote the query as</p> <pre><code>db.execSQL("CREATE TABLE pdetails( phone INTEGER PRIMARY KEY ASC, fname TEXT, lname TEXT, gender TEXT, email TEXT, mainpin INTEGER)"); </code></pre> <p>when I click the submit button data is inserted in database, but the problem is data is inserted with repeated primary keys. Can you please solve my problem? my insertion code is :</p> <pre><code> long flag = 0; int id = 1; SQLiteDatabase db = helper.getWritableDatabase(); Cursor cursor = db.query("pdetails", new String[]{"count(*) phone"}, null, null, null, null, null); while(cursor.moveToNext()) { int idFromDatabase = cursor.getInt(cursor.getColumnIndex("phone")); if(idFromDatabase != 0) { id = 1 + idFromDatabase; } } ContentValues values = new ContentValues(); //values.put("ID", id); values.put("fname", fnametxt.getText().toString().trim()); values.put("lname", lnametxt.getText().toString().trim()); if(male.isChecked()) { values.put("gender","male"); } else values.put("gender", "Female"); values.put("email", emailtxt.getText().toString()); values.put("phone", Integer.parseInt(phone.getText().toString())); values.put("mainpin", mainpin.toString()); flag = db.insert("pdetails", null, values); if(flag != -1) { Toast toast = Toast.makeText(getApplicationContext(), "You have successful inserted this record into database! "+flag, Toast.LENGTH_LONG); toast.show(); db.close(); return; } else { Toast toast = Toast.makeText(getApplicationContext(), "An error occured when insert this record into database!", Toast.LENGTH_LONG); toast.show(); db.close(); return; } } } } </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.
