Java android.database.CursorIndexOutOfBoundsException:请求索引8，大小为8

我遇到以下问题，任何帮助都会非常有帮助（我总是向上投票）：

出于某种原因，我的代码记录了我认为应该在两个集合中完成的事情，这是在六个集合中完成的，并且给了我一个错误

这是我的密码：

  package com.nxstudio.suratbus;

    import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;

public class DBHelper {

public void insert_coordinates(Context context){

    try {

        SQLiteDatabase eventsDB = context.openOrCreateDatabase("Coordinates", Context.MODE_PRIVATE, null);

        eventsDB.execSQL("CREATE TABLE IF NOT EXISTS coordinates (latitude VARCHAR,longitude VARCHAR,station VARCHAR)");

        eventsDB.execSQL("INSERT INTO coordinates (latitude, longitude ,station) VALUES ('1', '1','Station1')");

        eventsDB.execSQL("INSERT INTO coordinates (latitude, longitude ,station) VALUES ('2', '2','Station2')");

        Cursor c = eventsDB.rawQuery("SELECT * FROM coordinates", null);

        int latIndex = c.getColumnIndex("latitude");
        int longIndex = c.getColumnIndex("longitude");
        int stationIndex = c.getColumnIndex("station");

        if (c != null && c.moveToFirst()){

        while (c != null) {

            Log.i("lat", c.getString(latIndex));
            Log.i("long", Integer.toString(c.getInt(longIndex)));
            Log.i("Station", Integer.toString(c.getInt(stationIndex)));

            c.moveToNext();
        }
    }


    }
    catch (Exception e) {

        e.printStackTrace();

    }



}

提前感谢

试试这个：

while (c.moveToNext();) {
        Log.i("lat", c.getString(latIndex));
        Log.i("long", Integer.toString(c.getInt(longIndex)));
        Log.i("Station", Integer.toString(c.getInt(
    }

---

这将防止光标越过最后一个条目

要修复崩溃，请更换

while (c != null) {
    //...
    c.moveToNext();
}

用例如

do {
     //...
} while (c.moveToNext());

这样，当没有更多结果时，循环将终止

---

对于“两组在六组中完成”问题，您可以在

创建表之前添加
删除表（如果存在坐标）
，以删除包含较旧数据的旧表。
您的光标没有索引8，因此您得到
游标索引自动边界异常


因此，在从该索引获取值之前，应该检查游标是否包含该索引

 do {
     if (mCursor.getCount() > latIndex && mCursor.getCount() > longIndex && mCursor.getCount() > stationIndex) {
         Log.i("lat", c.getString(latIndex));
         Log.i("long", Integer.toString(c.getInt(longIndex)));
         Log.i("Station", Integer.toString(c.getInt(stationIndex)));
     }
 } while (c.moveToNext());

你混淆了行和列索引，循环永远不会终止。嘿，潘文林谢谢你的尝试，我很感激
