手势识别 为啥不好用？ 求指导

[阿瑞拉斯]

public class MainActivity extends Activity implements OnTouchListener, OnGestureListener{

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

@Override
public boolean onDown(MotionEvent e) {
// TODO Auto-generated method stub
Log.d("test", "sssssssssssssss");
return false;
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
// TODO Auto-generated method stub
Log.d("test", "DDDDDDDDDDDDDDDDDDDDDDDD");
return false;
}

@Override
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub
Log.d("test", "FFFFFFFFFFFFFFFF");
}

@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
float distanceY) {
// TODO Auto-generated method stub
Log.d("test", "x > "+distanceX+" y >"+distanceX);
return false;
}

@Override
public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub
Log.d("test", "HHHHHHHHHHHHHHHHHHHHHHHHH");
}

@Override
public boolean onSingleTapUp(MotionEvent e) {
// TODO Auto-generated method stub
Log.d("test", "EEEEEEEEEEEEEEEEEEEEEEEEE");
return false;
}

@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
Log.d("test", "YYYYYYYYYYYYYYYYYYYYYYY");
return false;
}

}
为啥没用任何log出来呢

能不能 不用view的ontouchListener 直接用activity的呢？？？ 求指导

[阿瑞拉斯]

没人理我阿

[ESC尛蜜蜂]

@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
Log.d("test", "YYYYYYYYYYYYYYYYYYYYYYY");
return mygesture.onTouchEvent(event);
}

你没在布局中 .setOnTouchListener(this);

引用 2 楼 a511341250 的回复:

@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
Log.d("test", "YYYYYYYYYYYYYYYYYYYYYYY");
return mygesture.onTouchEvent(event);
}

你没在布局中 .setOnTouchListener(this);

GestureDetector mygesture = new GestureDetector(this);

GestureDetector mygesture = new GestureDetector(this);[/quote] 求指导 怎么才能显示这些log呢 ？
