클릭하면 Logcat에는 원하는 값이 잘 나옵니다.
근데 토스트를 쓰려고 하니 context로 뭘 써야 할지 모르겠습니다.
getApplicationContext()등도 안되더라구요.
imgBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Log.i("buttonclick", v.getTag());
Toast.makeText(context, v.getTag(), Toast.LENGTH_SHORT);
}
});어떤 걸 잡아 줘야 토스트 메세지를 볼 수 있을까요?
Logcat으로 찍어보니 Context값은 제대로 넘어왔는데 왜 안뜨는지를 모르겠습니다.
Toast.makeText(context, v.getTag(), Toast.LENGTH_SHORT).show();
제가 공부할때 해봤던데 말한게 맞는지 모르겠네요

}
그리고 해당 Context 값을 가져오면되지요...
MyAdpater my = new MyContext(getApplicationContext() , xxxxxx)
하고 MyAdapter의 생성자에서
private Context com;
MyAdapter(Context com , xxxx){
this.com = com '
}
하고 getView 에서 com을 넣으면되지요.....
저방법외에도 여러방법이 있을듯...
