检查你的号码。列的名称及其名称cursor.getColumnCount()
和cursor.getColumnName(0).
。如果列数为2
,则光标有两列
cursor.moveToFirst();
String columnName1 = cursor.getColumnName(0);
String columnName2 = cursor.getColumnName(1);
String str1 = cursor.getString(cursor.getColumnIndex(columnName1)));
String str2 = cursor.getString(cursor.getColumnIndex(columnName2)));
editext1.seText(str1);
editext2.seText(str2);
完成从数据库获取数据后,使用cursor.close();

// Activity.onCreate function
EditText etfirstname= (EditText)findViewById(R.id.firstname);
EditText etlastname= (EditText)findViewById(R.id.lastname);
MyDatabase database = new MyDatabase(this);
Cursor c = database.queryRaw("SELECT firstname, lastname FROM users WHERE id=1"); // query data from database
if(c.moveToFirst()){
etfirstname.setText(c.getString(0)); // read firstname
etlastname.setText(c.getString(1)); // read lastname
}
c.close(); // dont forget to close cursor!
