推荐答案

我得到了这个有些pretty好成绩，所以希望这可以帮助你和任何一个。这个想法很简单。

I got some pretty good results with this, so hope this helps you or any one. The idea is simple.

位置要设置动画什么的这是通过XML的最终位置，然后我用 TranslateAnimation 和值设置它的 任何浮点值和将值为 0 。通过这种方式，窗口小部件/视图和动画来在你已经在XML中定位它的地方休息。

Position what you want to animate to it's final position via xml then I use TranslateAnimation and set its from values to any float values and to values as 0. In this way the widget/view animates and comes to rest in the place where you have positioned it in xml.

一个小例子来一个动画的TextView 从屏幕到XML中指定的位置之外。

A small example to animate a TextView from outside the screen to its position specified in xml.

//This is just for getting the from value, from where animation starts.
WindowManager wm = (WindowManager) mContext
        .getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
int width = display.getWidth();

Animation  moveRighttoLeft = new TranslateAnimation(width, 0, 0, 0);
moveRighttoLeft.setDuration(700);

AnimationSet animation = new AnimationSet(false);
animation.addAnimation(moveRighttoLeft);
myTextView.setAnimation(animation);

下面是XML的

<TextView
    android:id="@+id/mytextview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="This is a Text View"
    android:layout_marginLeft="30dp"/>
