问题 I have created a class which extends Gallery. There is no onCreate() method in super Class, and I'm unable to run my intent. This is my sample code: this.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View v, int position, long id) { Intent intent = new Intent(v.getContext(), ClassName.class); startActivity(intent); }} The following attempt also failed to work: Intent intent = new Intent(ThisClassName.this, ClassName

问题 There are some answers using java in stackoverflow but i am unable to convert it into kotlin code. I am new to kotlin.
