如何使相对布局从底部到顶部动画变小,并使用平移动画停在150dp的高度?这就是我得到的。
TranslateAnimation translation = new TranslateAnimation(1.0f, 1.0f, relativeLayout.getHeight(), 0.0f);
translation.setDuration(2000);
relativeLayout.startAnimation(translation);

据我了解,您需要将布局从下到上或从上到下翻译。试试这个
自下而上
public void SlideToAbove() {
Animation slide = null;
slide = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
0.0f, Animation.RELATIVE_TO_SELF, -5.0f);
slide.setDuration(400);
slide.setFillAfter(true);
slide.setFillEnabled(true);
rl_layout.startAnimation(slide);
slide.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
rl_layout.clearAnimation();
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
rl_layout.getWidth(), rl_layout.getHeight());
lp.setMargins(0, 0, 0, 0);
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
rl_layout.setLayoutParams(lp);
}
});
}
从上到下
public void SlideToDown() {
Animation slide = null;
slide = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
0.0f, Animation.RELATIVE_TO_SELF, 5.2f);
slide.setDuration(400);
slide.setFillAfter(true);
slide.setFillEnabled(true);
rl_layout.startAnimation(slide);
slide.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
rl_layout.clearAnimation();
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
rl_layout.getWidth(), rl_layout.getHeight());
lp.setMargins(0, rl_layout.getWidth(), 0, 0);
lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
rl_layout.setLayoutParams(lp);
}
});
}
