我正在使用Android中的网格视图为商店开发客户详细信息.我使用我的数据库获取了客户的详细信息.我需要使用警报框更新客户处理的股票,以便在执行交易时输入库存数量.
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"

并且,对于每一行,我使用了自定义的Xml文件..
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:layout_weight="1" />
<TextView
android:layout_width="50px"

我在Oncreate()方法上使用了customergrid.xml,并在Grid创建中使用customerrow.xml,如下面的代码所示.
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);
}

最后,我使用带有编辑框的警报框来获取客户库存数量的输入.我用这个任务..
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..
}
});
