Solution to the problem of repeatedly executing getView when ListView is refreshed multiple times in Android

I didn’t notice that listview’s getView would be executed multiple times before. This time because the layout was more complicated, I went to breakpoint tracking during testing and found that the same piece of data was being executed repeatedly. I thought it was strange, so I searched online. The explanations on the Internet are basically the same, that is, when the ListView is laid out, neither height nor width is fill_parent, resulting in continuous calculation of height and continuous refreshing. Or its parent container is not set to fill_parent.

If the layout is too complex, it is unrealistic to adjust everything according to fill_parent. So I thought of another solution, which is to dynamically fix the height.
After the program runs, fix the height of the ListView and then initialize the Item information.

private void fixedListView(){ 
listView = (ListView) findViewById(R.id.listview); 
ViewGroup.LayoutParams params = listView.getLayoutParams(); 
layout = (HorizontalScrollView) findViewById(R.id.layout); 
params.height = layout.getHeight(); //需要设置的listview的高度，你可以设置成一个定值，也可以设置成其他容器的高度，如果是其他容器高度，那么不要在oncreate中执行，需要做延时处理，否则高度为0 
listView.setLayoutParams(params); 
}

It is found that the refresh speed of ListView is greatly accelerated. Colleagues also solved the problem that if there is a listener for addTextChangedListener(new TextWatcher() in the text input EditText in Item, the listening code will be executed multiple times.
