如果我们在C＃.net中应用，此代码不会更改颜色。让我知道这是什么问题？

Answer 1

dataGridView1.RowsDefaultCellStyle.SelectionBackColor = Color.Red;

Answer 2

更改DefaultCellStyle.BackColor而不是Style.BackColor，它是在单元格的Paint事件中实际使用的Style.BackColor。

更改代码以更改行中每个单元格的Style.BackColor应该可以解决问题。

public void listUpdater () {

    Cursor c = myDB.rawQuery("SELECT * FROM user", null);

    int titleIndex = c.getColumnIndex("title");

    titles.clear();

    if (c.moveToFirst()){

        do {

            Log.i("RESULT: ",c.getString(titleIndex));

            titles.add(c.getString(titleIndex));




        } while (c.moveToNext());


        adapter.notifyDataSetChanged();


    }

}
