The problem is there is no error but my data from a certain id, i passed to the second activity wont show. Here is my first activity :</p> <pre><code>lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; arg0, View arg1, int arg2,long arg3) { // Intent newI = new Intent(this,PDetail.class); Intent newI = new Intent (Create.this, PDetail.class); newI.putExtra("value", arg3); startActivity (newI); // db.getList(arg3); }}); </code></pre> <p>and here is my second activity :</p> <pre><code> public void get() { Bundle bundle = getIntent().getExtras(); long count = bundle.getLong("value"); TextView XView; //Toast.makeText(getApplicationContext(), count, Toast.LENGTH_SHORT).show(); XView = (TextView) findViewById(R.id.textView1); //XView.setText("Number: " + count); db.open(); Cursor z = db.getList(count); z.moveToFirst(); String a = z.getString(z.getColumnIndex("product")); XView.setText(a); db.close(); } </code></pre> <p>I've got no error but it just force closed.... Any clue ???</p> <p>This is the db.getList</p> <pre><code>public Cursor getList(long rowId) throws SQLException { Cursor mCursor = db.query(true, DATABASE_TABLE, new String[] {KEY_ROWID, KEY_PRODUCT,KEY_BRAND, KEY_PLACE, KEY_DATE, KEY_PRICE}, KEY_ROWID + "=" + rowId, null, null, null, null, null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } //---updates a contact--- public boolean updateList(long rowId, String product, String brand, String place, String date, String price) { ContentValues args = new ContentValues(); args.put(KEY_PRODUCT, product); args.put(KEY_BRAND, brand); args.put(KEY_PLACE, place); args.put(KEY_DATE, date); args.put(KEY_PRICE, price); return db.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null) &gt; 0; } } </code></pre> <p>Logcat show nothing useful i think...</p> <pre><code>07-31 15:26:26.049: W/dalvikvm(20436): threadid=1: thread exiting with uncaught exception (group=0x40018578) 07-31 15:26:26.049: E/AndroidRuntime(20436): FATAL EXCEPTION: main 07-31 15:26:26.049: E/AndroidRuntime(20436): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.first/com.test.first.PDetail}: android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1651) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1667) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:935) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.os.Handler.dispatchMessage(Handler.java:99) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.os.Looper.loop(Looper.java:130) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.app.ActivityThread.main(ActivityThread.java:3687) 07-31 15:26:26.049: E/AndroidRuntime(20436): at java.lang.reflect.Method.invokeNative(Native Method) 07-31 15:26:26.049: E/AndroidRuntime(20436): at java.lang.reflect.Method.invoke(Method.java:507) 07-31 15:26:26.049: E/AndroidRuntime(20436): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:867) 07-31 15:26:26.049: E/AndroidRuntime(20436): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:625) 07-31 15:26:26.049: E/AndroidRuntime(20436): at dalvik.system.NativeStart.main(Native Method) 07-31 15:26:26.049: E/AndroidRuntime(20436): Caused by: android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.database.AbstractCursor.checkPosition(AbstractCursor.java:580) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.database.AbstractWindowedCursor.checkPosition(AbstractWindowedCursor.java:214) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.database.AbstractWindowedCursor.getString(AbstractWindowedCursor.java:41) 07-31 15:26:26.049: E/AndroidRuntime(20436): at com.test.first.PDetail.get(PDetail.java:32) 07-31 15:26:26.049: E/AndroidRuntime(20436): at com.test.first.PDetail.onCreate(PDetail.java:18) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-31 15:26:26.049: E/AndroidRuntime(20436): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1615) 07-31 15:26:26.049: E/AndroidRuntime(20436): ... 11 more </code></pre>

    3. COWell, looks like a "CursorIndexOutOfBoundsException" is being thrown. And the fact that you have a boolean updateList method inside your getList method looks plain weird! But that could be formatting. What happens when you add some System.outs and also z.getCount() in your void get() method (immediately after the cursor is called)?

Querying!

 
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).
