-
任何帮助?

这两种方法对于快速解决问题非常有用:
Animation slide_out_left = AnimationUtils.makeOutAnimation(getActivity(),false);
Animation slide_in_right = AnimationUtils.makeInAnimation(getActivity(), true);
Animation slide_out_right = AnimationUtils.makeOutAnimation(getActivity(),true);
Animation slide_in_left = AnimationUtils.makeInAnimation(getActivity(), false);
here是方法的文档,因为你会看到第二个参数是选择边的标志。
结果类似于Rodrigo之前编写的内容,但它需要2行代码,并且不需要定义自定义动画。

答案如下:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ViewFlipper flipper = findViewById(R.id.flipper);
flipper.setOnTouchListener(this);
}
private void myOnTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_MOVE:
mDragged = true;
break;
case MotionEvent.ACTION_DOWN:
mDragged = false;
mXbefore = event.getX();
break;
case MotionEvent.ACTION_UP:
if(mDragged){
vf = (ViewFlipper) v;
mXafter = event.getX();
if(mXafter > mXbefore){
vf.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.right_to_left_in));
vf.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.right_to_left_out));
vf.showNext();
}else{
vf.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.left_to_right_in));
vf.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.left_to_right_out));
vf.showPrevious();
}
}
mDragged = false;
break;
default:
break;
}
}

</ViewFlipper>
