    <p>I am setting my textview using columns from a sqlite database file.Problem is that when i change the view back and forth, there is a very obvious lag while it retrieves from the database.Here is the code: </p> <pre><code>public class Flipcard extends Activity implements OnClickListener { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); LinearLayout layMain = (LinearLayout) findViewById(R.id.FlashCardFront); layMain.setOnClickListener(this); Cursor cur; DbH db = null; TextView tv=(TextView) findViewById(R.id.TV_Word); TextView txtView=(TextView) findViewById(R.id.TV_CardNo); try { db=new DbH(this); } catch (IOException e2) { e2.printStackTrace(); } try { db.createdatabase(); } catch (IOException e) { e.printStackTrace(); } db.opendatabase(); cur=db.data(); cur.moveToFirst(); tv.setText(cur.getString(0)); cur.close(); } public void onClick(View v) { Intent i=new Intent(this,Flipcard_back.class); startActivity(i); } } </code></pre> <p>the other java file that is being called on click is: </p> <pre><code> public class Flipcard_back extends Activity implements OnClickListener{ /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main_back); LinearLayout layMain = (LinearLayout) findViewById(R.id.FlashCardRear); layMain.setOnClickListener(this); } public void onClick(View v) { Intent i=new Intent(this,Flipcard.class); startActivity(i); } } </code></pre> <p>which is actually calling previous one.The problem is i'm one a very initial phase on my app development.Right now i am only trying to change two textviews in first java file using my database.When i switch back and forth there is a lag of around a second.How do i correct it? am i doing something wrong. Also i am not able to retrieve all the rows using getstring(1) etc.Why so?How do i get the columns one by one?</p>

    1. COEdit: Logcat shows following every time i switch back and forth: need to grow: mSize=1048576, size=70, freeSpace()=26, numRows=2736 not growing since there are already 2736 row(s), max size=1048576 failed allocating fieldDir at startPos 0row 2736. what does this mean?

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.
