個人遇到的問題判斷按鈕的點擊事件還是滑動事件
private boolean button1Down = false; private boolean button2Down = false; private boolean pointInRect(float x, float y, int w, int h) { if (x < 0) { return false; } if (x > w) { return false; } if (y < 0) { return false; } if (y > h) { return false; } return true; }
判斷按鈕坐標是否在矩形區域內
tv_button_group.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: button1Down = pointInRect(event.getX(), event.getY(), v.getWidth(), v.getHeight()); break; case MotionEvent.ACTION_MOVE: for(int i=0; i<event.getHistorySize(); i++) { if(!pointInRect(event.getHistoricalX(i), event.getHistoricalY(i), v.getWidth(), v.getHeight())) { button1Down = false; break; } } break; case MotionEvent.ACTION_UP: // 判斷是否為點擊 if (button1Down && pointInRect(event.getX(), event.getY(), v.getWidth(), v.getHeight())) { if (initdata.get(position).isIsJoined()) { SessionHelper.startTeamSession(MainActivity.this, initdata.get(position).getGroupId()); } else { joinGroup(initdata.get(position).getGroupId()); } } else { if (event.getY() < -300) { recyclerView.setVisibility(View.GONE); iv_data.setVisibility(View.GONE); ll_bottom.setVisibility(View.GONE); vw_view.setVisibility(View.GONE); rl_deta.setVisibility(View.GONE); mTitleWidget.setVisibility(View.GONE); im_fanhui.setVisibility(View.VISIBLE); rl_group.setVisibility(View.VISIBLE); itData(mLongitude, mLatitude); uiSettings.setScrollGesturesEnabled(true); //禁止拖拽 isoncl = false; return true; } } break; } return true; } });
