Question

我不确定我应该做什么。我尝试了各种代码但没有效果。

我想显示一个包含列＆＃34;排名＆＃34;，＆＃34;团队名称＆＃34;和＆＃34;已完成＆＃34;。排名是指每个团队的位置（根据他们完成的位置数量）和完成列是指每个团队当前完成的位置数。

下面的数据库表是我正在使用的数据库表。这是我要在表格中显示的UI图像：table UI

请告诉我，我想如何接近它？以及我可以用它们编码的代码。我尝试过使用arraylist或游标等方法，但它不起作用。

我的数据库

public class DatabaseHelperGameMaster extends SQLiteOpenHelper {
//private static final int DATABASE_VERSION = 1;
public static final String DATABASE_NAME = "gemquest2.db";
public static final String TABLE_NAME = "gameMaster_table";
public static final String COL_ID = "ID";
public static final String COL_Team_Name = "TeamName";
public static final String COL_Location = "Location";

public DatabaseHelperGameMaster(Context context) {
    super(context, DATABASE_NAME, null, 1);
    SQLiteDatabase db = this.getWritableDatabase();
}

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL("create table " + TABLE_NAME + "(ID INTEGER PRIMARY KEY AUTOINCREMENT, TeamName TEXT, Location INTEGER)");

    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES ('TeamBurden', 1)");
    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES ('Fantastic4', 1)");
    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES ('TeamMN', 1)");
    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES ('JamesFamily', 2)");
    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES ('GossipBoys', 2)");
    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES ('TeamMN', 3)");
    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES ('Fantastic4', 3)");
    db.execSQL("INSERT INTO " + TABLE_NAME + "(TeamName, Location) VALUES('TeamBurden', 5)");


}

@Override
public void onUpgrade(SQLiteDatabase db, int i, int i1) {
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
    onCreate(db);
}

我的表格布局代码

我认为你可以使用SimpleCursorAdapter和Cursor来处理listview。结果将是您想要的。请查看
