在android中使用批处理操作在sqlite中插入数据

// 创建SQLite数据库
public class MyDatabaseHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "my_database";
    private static final int DATABASE_VERSION = 1;

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // 创建表
        String createTableQuery = "CREATE TABLE IF NOT EXISTS my_table (id INTEGER PRIMARY KEY, name TEXT)";
        db.execSQL(createTableQuery);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 升级数据库
        String dropTableQuery = "DROP TABLE IF EXISTS my_table";
        db.execSQL(dropTableQuery);
        onCreate(db);
    }
}

// 定义数据模型类
public class MyDataModel {
    private int id;
    private String name;

    public MyDataModel(int id, String name) {
        this.id = id;
        this.name = name;
    }

    // 省略getter和setter方法
}

// 执行批处理操作
public class MainActivity extends AppCompatActivity {
    private MyDatabaseHelper dbHelper;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        dbHelper = new MyDatabaseHelper(this);
        SQLiteDatabase db = dbHelper.getWritableDatabase();

        try {
            // 开启事务
            db.beginTransaction();

            // 执行批处理操作
            for (int i = 0; i < 1000; i++) {
                MyDataModel data = new MyDataModel(i, "Name " + i);

                ContentValues values = new ContentValues();
                values.put("id", data.getId());
                values.put("name", data.getName());

                db.insert("my_table", null, values);
            }

            // 标记事务成功，提交事务
            db.setTransactionSuccessful();
        } finally {
            // 结束事务
            db.endTransaction();
        }

        db.close();
    }
}
