Question

我想在textview中反向显示SQLite中的行数据，例如，如果我的行是：＆＃34; A＆＃34;，＆＃34; B＆＃34;，＆＃34; C＆＃34;，＆＃34; D＆＃34;，＆＃34; E＆＃34; 我想表明：＆＃34; E＆＃34;，＆＃34; D＆＃34;，＆＃34; C＆＃34;，＆＃34; B＆＃34;，＆＃34; A＆＃34;

这是我的代码：

Cursor c = myDB.rawQuery("SELECT * FROM mydataBase", null);
int rows = c.getCount();
int cols = c.getColumnCount();

    c.moveToFirst();

    // outer for loop
    for (int i = 0; i < rows; i++) {
        TextView myTableRowTextView = new TextView(this);

        TableRow row = new TableRow(this);

        // inner for loop
        for (int j = 0; j < cols; j++) {
            myTableRowTextView = new TextView(this);
            myTableRowTextView.setGravity(Gravity.CENTER);
            myTableRowTextView.setTextSize(18);

            Cursor cc = myDB.rawQuery("SELECT * FROM myDataBase", null); 
            myTableRowTextView.setText(c.getString(j));
            row.addView(myTableRowTextView);
        }
        c.moveToNext();
        myTableLayout.addView(row);
    }

问题在于：myTableRowTextView.setText（c.getString（j））; 在textView中显示我的行，有人可以帮我吗？

您可以使用其他方式列出所有列

for (int j = cols -1; j > -1; j--) {
            myTableRowTextView = new TextView(this);
            myTableRowTextView.setGravity(Gravity.CENTER);
            myTableRowTextView.setTextSize(18);

            Cursor cc = myDB.rawQuery("SELECT * FROM myDataBase", null); 
            myTableRowTextView.setText(c.getString(j));
            row.addView(myTableRowTextView);
        }

如何反向调用SQLite行数据？
