应该放置超级(某物)的地方？

Question

我想知道super.onPreExecute()应该放在哪里？或换句话说,这是正确的代码:

@Override
protected void onPreExecute() {
    super.onPreExecute();
    RelativeLayout parent = (RelativeLayout) findViewById(R.id.layoutHomeInfo);
    RelativeLayout.LayoutParams params = (LayoutParams) parent.getLayoutParams();
    params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    params.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    progress = new ProgressBar(mContext);
    parent.addView(progress, params);
}

要么

@Override
protected void onPreExecute() {
    RelativeLayout parent = (RelativeLayout) findViewById(R.id.layoutHomeInfo);
    RelativeLayout.LayoutParams params = (LayoutParams) parent.getLayoutParams();
    params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    params.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    progress = new ProgressBar(mContext);
    parent.addView(progress, params);
    super.onPreExecute();
}

Answer 1

哪里都行.

无论是错误的,它只是一切都取决于当你想调用父功能,那就是一切都取决于你(开发商).
