我希望能够动画化两个不同的布局。
例如：
我已经按照自己的意愿完成了动画，现在只是想要动画化另一个XML布局。 有一个名为LayoutAnimationController的类，但我真的不知道如何使用它。 是否有人可以给我指点方向，提供示例或详细说明。
这是我用于动画化的代码：
TranslateAnimation slide = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 300f, 0,0 );
slide.setAnimationListener(AL);
slide.setFillAfter(true);
slide.setDuration(1000);
parentlayout.startAnimation(slide);
更新 由于得到了许多赞，我决定把一个示例项目放进了Git存储库。 请参见我的回答获取链接。
在花费了两天时间阅读类似问题及其它人是如何解决的之后，我终于成功地创建了我想要的东西。 我无法通过2个不同的XML文件实现它，但我怀疑这是不可能的。
然而，我遇到了一些问题。
在第一个动画结束后，按钮无法被点击。 这是因为动画显示所有内容都已移动，但它没有更新布局，所以按钮仍然位于动画开始时的位置。 所以我必须计算出布局的新位置。
我记得在某处看到过，在3.0中这已经不再是问题了，但如果我错了，请您指正。
另一个问题是，当我的动画最终按照我想要的方式工作时，底层视图在动画完成之前消失了，因为我调用了 view.setVisabilty(View.GONE);。
现在的问题是，当我没有调用该方法时，动画会卡顿一秒钟，然后快速跳转到动画的最终位置。
所以我添加了一个空的LinearLayout（可以是任何内容），默认属性为GONE，在动画开始时将其设置为VISIBLE。当您撤销动画时，再次将其设置为GONE。
这样做后，动画就能按照我想要的方式工作了。
如果您正在使用Rel、Linear或任何其他布局，则无法按Z顺序堆叠视图，因此必须使用SurfaceView。
这是main.xml：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout1"
android:layout_width="fill_parent"

<Button

</LinearLayout>
</RelativeLayout>
</RelativeLayout>
这里是Java代码
public class MenuAnimationActivity extends Activity {

private int screenWidth;
private int animToPostion;
// TODO change the name of the animToPostion for a better explanation.
private boolean menuOpen = false;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
buttonSwitch = (Button)findViewById(R.id.button);

fakeLayout = (View)findViewById(R.id.fake_layouy);
subViewListView.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , listViewDummyContent));
display = getWindowManager().getDefaultDisplay();
screenWidth = display.getWidth();
int calcAnimationPosition = (screenWidth /3);
// Value where the onTop Layer has to animate
// also the max width of the layout underneath
// Set Layout params for subLayout according to calculation
animToPostion = screenWidth - calcAnimationPosition;
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(animToPostion, RelativeLayout.LayoutParams.FILL_PARENT);
subLayout.setLayoutParams(params);
topLayout.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
if (menuOpen == true) {
animSlideLeft();
}
}
return false;
}
});
buttonSwitch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(menuOpen == false){
animSlideRight();
} else if (menuOpen == true) {
animSlideLeft();
}
}
});
AL = new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
buttonSwitch.setClickable(false);
topLayout.setEnabled(false);
}
@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
@Override
public void onAnimationEnd(Animation animation) {
if(menuOpen == true) {
Log.d("", "Open");
topLayout.layout(oldLeft, oldTop, oldLeft + topLayout.getMeasuredWidth(), oldTop + topLayout.getMeasuredHeight() );
menuOpen = false;
buttonSwitch.setClickable(true);
topLayout.setEnabled(true);
} else if(menuOpen == false) {
Log.d("","FALSE");
topLayout.layout(newleft, newTop, newleft + topLayout.getMeasuredWidth(), newTop + topLayout.getMeasuredHeight() );
topLayout.setEnabled(true);
menuOpen = true;
buttonSwitch.setClickable(true);
}
}
};
}
public void animSlideRight(){
fakeLayout.setVisibility(View.VISIBLE);
newleft = topLayout.getLeft() + animToPostion;
newTop = topLayout.getTop();
TranslateAnimation slideRight = new TranslateAnimation(0,newleft,0,0);
slideRight.setDuration(500);
slideRight.setFillEnabled(true);
slideRight.setAnimationListener(AL);
topLayout.startAnimation(slideRight);
}
public void animSlideLeft() {
fakeLayout.setVisibility(View.GONE);
oldLeft = topLayout.getLeft() - animToPostion;
oldTop = topLayout.getTop();
TranslateAnimation slideLeft = new TranslateAnimation(newleft,oldLeft,0,0);
slideLeft.setDuration(500);
slideLeft.setFillEnabled(true);
slideLeft.setAnimationListener(AL);
topLayout.startAnimation(slideLeft);
}
}
我在触摸视图上进行了一些额外的编码。
最终结果如下所示：
动画之前
第一个动画后
第二个动画后回到左边时，状态与第一张图片相同。
所有帮助我的帖子都应该得到一些认可，但我找不到它们中的任何一个。
编辑
GIT https://bitbucket.org/maikelbollemeijer/sidepanelswitcher
更新： https://github.com/jfeinstein10/SlidingMenu 此库与Actionbar Sherlock兼容。
希望这有所帮助。

当侧边栏打开时，它看起来像这样。
