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 + "=?";
