SimpleCursorAdapter直接使用的方法：
SimpleCursorAdapter允许你绑定一个游标的列到ListView上，并使用自定义的layout显示每个项目。
SimpleCursorAdapter的创建，需要传入当前的上下文、一个layout资源，一个游标和两个数组：一个包含使用的列的名字，另一个（相同大小）数组包含View中的资源ID，用于显示相应列的数据值。
//第一步：从数据库读取数据
dbHelper = new DBHelper(HistoryOrderActivity.this);
database = dbHelper.getWritableDatabase();
cursor = database.rawQuery("SELECT * FROM "+DBHelper.TABLE_ORDER+" where feedbackTime is not null", null);
//startManagingCursor(cursor); 被遗弃的方法，主要是把cursor的生命周期交由Activity管理
String[] fromColumns = new String[] {
"orderDescription",
"orderEffectiveTime",
"orderConsumeTime",
"promotion",
"feedbackInfo",
"feedbackTime",
};
int[] toLayoutIDs = new int[] {
R.id.description,
R.id.effectiveTime,
R.id.consumeTime,
R.id.promotion,
R.id.feedbackInfo,
R.id.feedbackTime};
adapter = new SimpleCursorAdapter(this, R.layout.histortyorder, cursor, fromColumns, toLayoutIDs,0);
SimpleCursorAdapter自定义的使用：
//第一步：从数据库读取数据
dbHelper = new DBHelper(HistoryOrderActivity.this);
database = dbHelper.getWritableDatabase();
cursor = database.rawQuery("SELECT * FROM "+DBHelper.TABLE_ORDER+" where feedbackTime is not null", null);
//startManagingCursor(cursor); 被遗弃的方法，主要是把cursor的生命周期交由Activity管理
String[] fromColumns = new String[] {
"orderDescription",
"orderEffectiveTime",
"orderConsumeTime",
"promotion",
"feedbackInfo",
"feedbackTime",
};
int[] toLayoutIDs = new int[] {
R.id.description,
R.id.effectiveTime,
R.id.consumeTime,
R.id.promotion,
R.id.feedbackInfo,
R.id.feedbackTime};
if (cursor == null) {
return;
}
adapter = new HistoryOrderAdapter(HistoryOrderActivity.this, R.layout.histortyorder,
cursor, fromColumns, toLayoutIDs, 0);
适配器的实现：
public class HistoryOrderAdapter extends SimpleCursorAdapter {
private Cursor m_cursor;
private Context m_context;
private LayoutInflater miInflater;
public HistoryOrderAdapter(Context context, int layout, Cursor c,
String[] from, int[] to, int flags) {
super(context, layout, c, from, to, flags);
m_context = context;
m_cursor = c;
}
@Override
public void bindView(View arg0, Context arg1, Cursor arg2) {
View convertView = null;
if (arg0 == null) {
convertView = miInflater.inflate(R.layout.histortyorder, null);
} else {
convertView = arg0;
}
TextView tv_Description = (TextView) convertView
.findViewById(R.id.description);
TextView tv_EffectiveTime = (TextView) convertView
.findViewById(R.id.effectiveTime);
TextView tv_ConsumeTime = (TextView) convertView
.findViewById(R.id.consumeTime);
TextView tv_promotion = (TextView) convertView
.findViewById(R.id.promotion);
TextView tv_FeedbackInfo = (TextView) convertView
.findViewById(R.id.feedbackInfo);
TextView tv_FeedbackTime = (TextView) convertView
.findViewById(R.id.feedbackTime);
tv_Description.setText(arg2.getString(arg2
.getColumnIndex("orderDescription")));
tv_EffectiveTime.setText(ShopUtils.changeTimestampToTime(Long
.valueOf(arg2.getString(arg2
.getColumnIndex("orderEffectiveTime")))));
tv_ConsumeTime
.setText(ShopUtils.changeTimestampToTime(Long.valueOf(arg2
.getString(arg2.getColumnIndex("orderConsumeTime")))));
tv_promotion.setText(arg2.getString(arg2.getColumnIndex("promotion")));
tv_FeedbackInfo.setText(arg2.getString(arg2
.getColumnIndex("feedbackInfo")));
tv_FeedbackTime.setText(ShopUtils.changeTimestampToTime(Long
.valueOf(arg2.getString(arg2.getColumnIndex("feedbackTime")))));
}
}
HistoryOrderAdapter有点糙，需要改进。
