ListView

android:orientation

Set vertical / horizontal view inside layout

 

Listview

1. We should make list type to save data

List<String> data = new ArrayList<>();

 

2. Make Arrayadapter to connect array to listview

ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.listtype, data)

'This' means this activity, android.R.layout.listtype sets list type, data is a Array list.

 

3. Set adapter to list

list.setAdapter(adapter)

'list' should be the name of listview variable.

 

4. Add data

data.add("value");

 

5. Save change

adapter.notifyDataSetChanged();
