public class ListDetails { 

    public static ArrayList<model> getList(){ 
     ArrayList<model> subjectList = new ArrayList<>(); 
     subjectList.add(new model(R.drawable.phy,"Physics","4 chapters available")); 
     subjectList.add(new model(R.drawable.che,"Chemistry","5 chapters available ")); 
     subjectList.add(new model(R.drawable.que,"Model Questions","10 model Questions available")); 

     return subjectList; 
    } 
} 

Ich bin ein Anfänger, also hoffe ich, dass ich genügend Hilfe davon bekommen würde.

Answer 1

Es scheint also, dass Sie nicht versucht haben, Ihrem ListView einen Listener hinzuzufügen. Sie können diese AdapterView.OnItemClickListener

listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id){ 
     //.. launch your new activity here using Intent 
     Intent intent = new Intent(MainActivity.this, NewActivity.class); 
     startActivity(intent); 
    } 
}); 

Noch ein Hinweis über tun, sollten Sie wirklich besser auf Ihre Klassen zu benennen. Empfohlener Wert: Effective Java

Sie sollten auch lesen: Making a listview scroll smooth, die über das ViewHolder-Muster spricht, oder einfach zu einem RecyclerView bewegen, sobald Sie ein bisschen mehr Android kennen.
