代码如下
public Player getPlayer(String name) {
SQLiteDatabase db = this.getReadableDatabase();
String[] projection = {
PlayerEntry.COLUMN_NAME_PLAYER_NAME,
PlayerEntry.COLUMN_NAME_PLAYED_GAMES,
};
String selection = PlayerEntry.COLUMN_NAME_PLAYER_NAME ;
String[] selectionArgs = new String[1];
selectionArgs[0] = name;
Cursor cursor = db.query(
PlayerEntry.TABLE_NAME, // The table to query
projection, // The columns to return
selection, // The columns for the WHERE clause
selectionArgs, // The values for the WHERE clause
null, // don‘t group the rows
null, // don‘t filter by row groups
null // The sort order
);
if (cursor != null)
cursor.moveToFirst();
解决方法如下
String selection = PlayerEntry.COLUMN_NAME_PLAYER_NAME + "=?";
