这是我的ListActivity：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_list);
mDbHelper = new MyDbAdapter(this);
mDbHelper.open();
fillData();
registerForContextMenu(getListView());
}
private void fillData() {
// Get all of the rows from the database and create the item list
Cursor c = mDbHelper.fetchAllTransactions();
startManagingCursor(c);
// Create an array to specify the fields we want to display in the list
String[] from = new String[]{MyDbAdapter.KEY_DATE,MyDbAdapter.KEY_NAME};
// and an array of the fields we want to bind those fields to
int[] to = new int[]{R.id.row_date,R.id.row_name};
// Now create a simple cursor adapter and set it to display
setListAdapter(new SimpleCursorAdapter(this,R.layout.my_list_row,c,from,to));
}
这是我的行布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:id="@+id/row_date" android:layout_width="wrap_content" android:layout_height="fill_parent" />
<TextView android:id="@+id/row_name" android:layout_width="wrap_content" android:layout_height="fill_parent" />
</LinearLayout>
该日期实际上以int形式存储在sqlLite数据库中,因此它显示为整数.
有谁知道从int创建日期的方法,因此它不会显示为1216544611(或其他),而是显示为“ 12/11/2009 11:32”？
最佳答案
我怀疑您将需要编写自己的CursorAdapter来将int格式化为日期字符串.诀窍是实现bindView()在列表项显示之前对其进行格式化：
private final class MyCursorAdapter extends CursorAdapter {
MyCursorAdapter(Context context,Cursor c) {
super(context,c);
}
@Override public void bindView(View view,Context context,Cursor cursor) {
// Format the date string
TextView dateView = (TextView) view.findViewById(R.id.row_date);
long millis = cursor.getLong(cursor.getColumnIndex(MyDbAdapter.KEY_DATE));
dateView.setText(DateFormat.getDateInstance().format(new Date(milis)));
// Do the rest of your view formatting
...
}
@Override View public newView(Context context,Cursor cursor,ViewGroup parent) {
View view = getLayoutInflater().inflate(R.layout.my_list_row,null);
bindView(view,context,cursor);
return view;
}
}
并将其连接到onCreate()中的Activity：
setListAdapter(new MyCursorAdapter(this,c));
