이것은 내 확장보기입니다.
public class PieMenu extends FrameLayout{
private View _view;
private ArrayList<PieItem> mItems;
private Context _context;
public PieMenu(View view, Context context) {
super(context);
_context = context;
_view = view;
setWillNotDraw(false);
// TODO Auto-generated constructor stub
}
public void addPieMenu(int x, int y){
mItems = new ArrayList<PieItem>();
Path path = new Path();
path.addCircle(9, 9, 9, Path.Direction.CW);
PieItem item = new PieItem(_view,_context,path, x,y,40);
mItems.add(item);
//FrameLayout.LayoutParams lyp = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
//pieView.setLayoutParams(lyp);
//addView(pieView);
// animateIn();
invalidate();
}
@Override
protected void onDraw(Canvas canvas) {
Paint paint1 = new Paint();
paint1.setColor(Color.RED);
canvas.drawCircle(50, 50, 25, paint1);
this.draw(canvas);
//_view.draw(canvas);
}
}
이것이 나의 주요 활동입니다.
public class MainActivity extends Activity {
PieMenu pieMenu;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pieMenu = new PieMenu(getWindow().getDecorView().findViewById(android.R.id.content) ,MainActivity.this);
FrameLayout fl = (FrameLayout)findViewById(R.id.flayout);
fl.addView(pieMenu);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
int x = (int)event.getX();
int y = (int)event.getY();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
{
pieMenu.addPieMenu(x,y);
}
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_UP:
}
return false;
}
}
이것은 내 주요 activity.xml입니다.

내가 어디로 잘못 가고 있습니까?
PieMenu클래스에 다음 생성자가 필요합니다 .
public PieMenu(View view, Context context) {
super(context);
// ~
}
public PieMenu(View view, Context context, AttributeSet attrs) {
super(context, attrs);
// ~
}
편집 1
public PieMenu(View view, Context context, AttributeSet attrs, int style) {
super(context, attrs, style);
// ~
}
