我应该用什么代码替换它以显示aaaa,bbbb,cccc,dddd
最佳答案
以此替换您的代码,然后尝试
Cursor cursor = db.rawQuery("select * from sentmessages", null);
String dataToInsert = "";
cursor.moveToFirst();
dataToInsert = dataToInsert.concat(String.valueOf("aaaa")).concat(String.valueOf(", "));
cursor.moveToFirst();
dataToInsert = dataToInsert.concat(String.valueOf("bbbb")).concat(String.valueOf(", "));
cursor.moveToFirst();
dataToInsert = dataToInsert.concat(String.valueOf("cccc")).concat(String.valueOf(", "));
cursor.moveToFirst();
dataToInsert = dataToInsert.concat(String.valueOf("dddd")).concat(String.valueOf(", "));
shdb.setText(dataToInsert);
