强文本

我无法打开数据库并对其进行查询。我想访问使用意图值从不同的 java 文件传递​​的表行。请帮忙 ！

import java.io.File;
import java.util.ArrayList;
import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.Toast;

public class Finish_kitchen extends Activity {
    GridView gridView;
    private imageAdapter imageAdapter;
    private SQLiteDatabase db;
    private static String DB_Path = "/mnt/sdcard/Kitchen_Data.db";
    private Cursor c;
    private String path;
    private ListView listView1;
    private ArrayList<String> Steps;
    private ArrayList<String> Image_path;
    private ArrayList<String> Audio_path;
    private int count;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.finish_kit);
        listView1 = (ListView) findViewById(R.id.listView1);
        Steps = new ArrayList<String>();
        Image_path = new ArrayList<String>();
        Audio_path = new ArrayList<String>();
        path = getIntent().getStringExtra("path");
        db = SQLiteDatabase.openDatabase(DB_Path, null, SQLiteDatabase.OPEN_READWRITE);
        c = db.query(path, null, null, null, null, null, null);
        c.moveToFirst();
        Steps.add(c.getString(1));
        Toast.makeText(getApplicationContext(), "heyaa gotcha", Toast.LENGTH_LONG).show();
    }
}

c = db.query(path, null, null, null, null, null, null);

第一个参数应该是您的表名。但是你给出了一个文件路径。

这是错误消息-
