尝试使用contentProvider从sqlite中删除带条件的行

// 自定义ContentProvider类
public class MyContentProvider extends ContentProvider {
    private SQLiteDatabase database;

    @Override
    public boolean onCreate() {
        // 初始化数据库
        DBHelper dbHelper = new DBHelper(getContext());
        database = dbHelper.getWritableDatabase();
        return true;
    }

    @Override
    public int delete(Uri uri, String selection, String[] selectionArgs) {
        // 删除满足条件的行
        int rowsDeleted = database.delete(TABLE_NAME, selection, selectionArgs);
        getContext().getContentResolver().notifyChange(uri, null);
        return rowsDeleted;
    }

    // 其他方法的实现...

}

// 调用ContentProvider的delete()方法
Uri uri = Uri.parse("content://com.example.mycontentprovider/mytable");
String selection = "column1 = ?";
String[] selectionArgs = {"value1"};

int rowsDeleted = getContentResolver().delete(uri, selection, selectionArgs);
