有人可以帮我吗?我的记录没有更新。 我想edittext保持不变,但不太确定。
如何更改在编辑文本中放置的视图值,以更改为更新编辑文本时的值。 希望对此有所帮助 谢谢。

min.pval <- p.val
min.id <- i

}
# print the gene found:
cat(rownames(train.exprs)[min.id],min.pval,fill=T)
# refit the model for best gene found on training dataset:
best.lm.xval <- lm(train.d2r~train.exprs[min.id,])
# calculate predictions on test dataset:
test.exprs <- ALL.exprs[,xval.grps==i.xval]
test.d2r <- ALL.pdat[xval.grps==i.xval,"D2R"]
test.pred <- predict(
best.lm.xval,data.frame(t(test.exprs),test.d2r)

# accumulate squared errors of prediction:
s2.xval <- c(s2.xval,(test.pred-test.d2r)^2)

以上是本活动中使用的数据库的一部分。
活动main.java
public Cursor selectRow(String ID) {
String query = "Select * from " + TABLE_NAME + " where studentID = " + ID;
Cursor cursor = db.rawQuery(query, null);
return cursor;
}
public boolean updateData(String id, String fn, String ln, String ge, String cs, String a, String loc) {
ContentValues contentValues = new ContentValues();
contentValues.put("studentID", id);
contentValues.put("first_name", fn);
contentValues.put("last_name", ln);
contentValues.put("gender", ge);
contentValues.put("course_study", cs);
contentValues.put("age", a);
contentValues.put("location", loc);
db.update(TABLE_NAME, contentValues, "studentID = ?", new String[]{id});
return true;
}
我尝试过使用按钮来设置数据,但它仍然保持不变。
答案 0 :(得分:0)
很抱歉,我们没有读代码,如果有帮助,请拿出示例 只是逻辑。
public long updateNote(NoteModel noteModel) {
if (LOG_DEBUG) UtilLogger.showLogUpdate(TAG, noteModel, noteModel.getRow_pos());
long updatedRow = 0;
try {
ContentValues contentValues = new ContentValues();
contentValues.put(DBSchema.DB_TITLE, noteModel.getTitle());
contentValues.put(DBSchema.DB_IMAGE_PATH, noteModel.getImgUriPath());
contentValues.put(DBSchema.DB_SUB_TEXT, noteModel.getSub_text());
contentValues.put(DBSchema.DB_CREATE_DATE, noteModel.getCreateDate());
contentValues.put(DBSchema.DB_UPDATE_DATE, noteModel.getUpdateDate());
contentValues.put(DBSchema.DB_SCHEDULED_TIME_LONG, noteModel.getScheduleTimeLong());
contentValues.put(DBSchema.DB_SCHEDULED_TIME_WHEN, noteModel.getScheduledWhenLong());
contentValues.put(DBSchema.DB_SCHEDULED_TITLE, noteModel.getScheduledTitle());
contentValues.put(DBSchema.DB_IS_ALARM_SCHEDULED, noteModel.getIsAlarmScheduled());
contentValues.put(DBSchema.DB_IS_TASK_DONE, noteModel.getIsTaskDone());
contentValues.put(DBSchema.DB_IS_ARCHIVED, noteModel.getIsArchived());
updatedRow = mSqLiteDatabase.updateWithOnConflict(
DBSchema.DB_TABLE_NAME,
contentValues,
DBSchema.DB_ROW_ID + " =?", new String[]{String.valueOf(noteModel.get_id())}, mSqLiteDatabase.CONFLICT_REPLACE);
return updatedRow;
} catch (SQLException e) {
e.printStackTrace();
}
return updatedRow;
}
然后移动光标
public Cursor getCursorForAlarmScheduled(String passAlarmScheduledStatus) {
if (LOG_DEBUG)
Log.w(TAG, " pick all record with alarmScheduled 1 : " + passAlarmScheduledStatus);
return mSqLiteDatabase.rawQuery(DBSchema.DB_SELECT_ALL +
" WHERE " + DBSchema.DB_IS_ALARM_SCHEDULED + " = " + passAlarmScheduledStatus, null);
}
然后提取
//common operation for all,
public static List<NoteModel> extractCommonData(Cursor cursor, List<NoteModel> noteModelList) {
noteModelList = new ArrayList<>();
if (LOG_DEBUG) Log.i(TAG, "inside extractCommonData()");
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
NoteModel noteModel = new NoteModel();
noteModel.set_id(cursor.getInt(cursor.getColumnIndex(DBSchema.DB_ROW_ID)));
noteModel.setTitle(cursor.getString(cursor.getColumnIndex(DBSchema.DB_TITLE)));
noteModel.setImgUriPath(cursor.getInt(cursor.getColumnIndex(DBSchema.DB_IMAGE_PATH)));
noteModel.setSub_text(cursor.getString(cursor.getColumnIndex(DBSchema.DB_SUB_TEXT)));
noteModel.setCreateDate(cursor.getLong(cursor.getColumnIndex(DBSchema.DB_CREATE_DATE)));
noteModel.setUpdateDate(cursor.getLong(cursor.getColumnIndex(DBSchema.DB_UPDATE_DATE)));
noteModel.setScheduleTimeLong(cursor.getLong(cursor.getColumnIndex(DBSchema.DB_SCHEDULED_TIME_LONG)));
noteModel.setScheduledWhenLong(cursor.getLong(cursor.getColumnIndex(DBSchema.DB_SCHEDULED_TIME_WHEN)));
noteModel.setScheduledTitle(cursor.getString(cursor.getColumnIndex(DBSchema.DB_SCHEDULED_TITLE)));
noteModel.setIsAlarmScheduled(cursor.getInt(cursor.getColumnIndex(DBSchema.DB_IS_ALARM_SCHEDULED)));
noteModel.setIsTaskDone(cursor.getInt(cursor.getColumnIndex(DBSchema.DB_IS_TASK_DONE)));
noteModel.setIsArchived(cursor.getInt(cursor.getColumnIndex(DBSchema.DB_IS_ARCHIVED)));
noteModelList.add(noteModel);
} while (cursor.moveToNext());
}
cursor.close();
}
return noteModelList;
}
同样,我没有看过,只是从我的旧样本中复制而来 请找到需要的人,欢呼声
