我正在点击按钮删除数据库，我的删除方法如下
public int deleteDatabase(String tableName) {
SQLiteDatabase db = database.getWritableDatabase();
String whereClause = null; // delete all rows
String[] whereArgs = { null };
int count = db.delete(tableName, whereClause, whereArgs);
db.close();
return count;
}
if (DatabaseHelper.getInstance(getApplicationContext())
.isTableExists(MY_TABLE)) {
Log.d(TAG, "Table exist, delete database");
deleteDatabase(MY_LIST_TABLE);
}
错误如下：绑定参数过多。提供了1个参数，但该语句需要0个参数。
String whereClause = null; // delete all rows
String[] whereArgs = { null };
int count = db.delete(tableName, whereClause, whereArgs);
如果您提供了whereArgs，则还必须提供一个有效的where子句（带有?占位符）。像一样更改
int count = db.delete(tableName, null, null);
