I'm developing an Customer details for a shop using Grid view in android. I get the details of my Customers using my Database. I need to update the Stocks handled by the Customer using an alert box for entering the Stock Quantity while performing the Transaction..
customergrid.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tab1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<GridView
android:id="@+id/grid"
android:layout_width="fill_parent"
android:layout_height="357dp"
android:numColumns="1"
android:stretchMode="columnWidth" />
<Button
android:id="@+id/cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="cancel" />
</LinearLayout>
And, for each Row I have used a customized Xml file..
customerrow.xml
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TableRow>
<TextView
android:layout_width="50px"
android:layout_height="wrap_content"
android:id="@+id/row_ID"
android:padding="5px"
android:layout_weight="1" />
<TextView
android:layout_width="50px"
android:layout_height="wrap_content"
android:id="@+id/key_ID"
android:padding="5px"
android:layout_weight="1" />
<TextView
android:layout_width="50px"
android:layout_height="wrap_content"
android:id="@+id/key_Description"
android:padding="5px"
android:layout_weight="1" />
</TableRow>
</TableLayout>
And I have Used customergrid.xml on the Oncreate() method and use customerrow.xml in the Grid creation like as the following code..
public void FillGrid() {
DatabaseHelper sqdb = new DatabaseHelper(this);
sqdb.openDataBase();
Cursor cursor;
GridView grid = (GridView) findViewById(R.id.grvData);
cursor = sqdb.getGridData();
sqdb.close();
if (cursor != null) {
startManagingCursor(cursor);
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
R.layout.customerrow, cursor, new String[] { CustomerActivity.KEY_ROW_ID,
CustomerActivity.KEY_ID, CustomerActivity.KEY_DESCRIPTION }, new int[] {
R.id.txtGrv_id, R.id.txtGrvid, R.id.txtGrvDescription } );
adapter.setViewResource(R.layout.gridlayout);
grid.setAdapter(adapter);
}
And finally I used alert box with an editbox for getting the input of Customer's Stock Quantity. I use this for that task..
grid.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long arg3) {
AlertDialog.Builder b=new AlertDialog.Builder(MarkSheet.this);
b.setTitle("Employee Details");
LayoutInflater li=LayoutInflater.from(MarkSheet.this);
View v=li.inflate(R.layout.dialog, null);
b.setIcon(android.R.drawable.ic_input_get);
b.setView(v);
final TextView txtName=(TextView)v.findViewById(R.id.txtName);
final EditText Quantity=(EditText)v.findViewById(R.id.Quantity);
// Here I need to update the table while clicking the positive button, if I click negative button I need to cancel the Dialog box..
}
});
Anybody help me for Complete this task..
