ObjectAnimator 不反转
ObjectAnimator not reversing
我有一组视图可以在屏幕上向下移动并随后反转,但现在当我尝试移动 CardView 时,它会向下移动但不会向上移动。
当用户单击一个按钮时,它会提示视图集合删除 down/fade,当用户再次单击该按钮时,它们会 return。在 space 创建的 Views collection vanishing 中,一个 CardView 下拉。我有要下拉的 CardView,但是当用户单击按钮时,视图集合 return 而不是 CardView - 相反它就消失了。干杯!
MainActivity(注意:在 OnCreate() 中)
...
final View blankCard = findViewById(R.id.child_card_template);
blankCard.setVisibility(blankCard.INVISIBLE);
...
ImageButton btn = (ImageButton) findViewById(R.id.imageLeft);
btn.setOnClickListener(new View.OnClickListener() {
int click_Animation_Type = 0;
View viewTest = findViewById(R.id.child_card_template);
View viewCard = viewTest;
@Override
public void onClick(View view) {
switch(click_Animation_Type) {
case 0:
moveSecondRow();
moveCardViewLayout();
click_Animation_Type = 1;
break;
case 1:
rewindSecondRow();
rewindCardViewLayout();
click_Animation_Type = 0;
break;
}
}
public void moveCardViewLayout() {
View viewTest = findViewById(R.id.child_card_template);
ObjectAnimator viewTestMovi = ObjectAnimator.ofFloat(viewTest, "translationY", 0f, 258f);
if(viewTest.getVisibility()==View.INVISIBLE) {
viewTestMovi.setDuration(250);
viewTestMovi.start();
viewTest.setVisibility(viewTest.VISIBLE);
}
}
public void rewindCardViewLayout() {

viewTestMoviReverse.setDuration(250);
viewTestMoviReverse.start();
viewTest.setVisibility(viewCard.INVISIBLE);
//THERE'S NO ANIMATION, JUST TURNING INVISIBLE.
//Registers View is visible.
}
}
public void moveSecondRow() {
for (int i = 0; i < list.size(); i++) {
ObjectAnimator bottomRow = ObjectAnimator.ofFloat(list.get(i), "translationY", 0f, 300f);
bottomRow.setDuration(250);//set duration
Animation fadeOutAnimation = AnimationUtils.loadAnimation(MainActivity.this, R.anim.fade_out_anim);
bottomRow.start();//start animation
list.get(i).startAnimation(fadeOutAnimation);
list.get(i).setVisibility(View.GONE);
}

public void rewindSecondRow() {
for (int i = 0; i < list.size(); i++) {

bottomRow.start();//start animation

});
每次click_Animation_Type
都从0开始。将click_Animation_Type = 0;
层放在setContentView
下面。
