安卓圖像視圖比例尺動畫

Question

嗨我想知道如何縮放動畫標誌和移動其位置？

我有一個if語句運行一些檢查，然後當它完成我希望它縮小圖像視圖（標誌）並將其向上移動。

public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.layout_initialsetup); 
     preChecks(); 
    } 

public void preChecks(){ 
    //check for internet connection 

    //check version 
    String curVersion = getResources().getString(R.string.app_versionCode); 
    int curVer = Integer.parseInt(curVersion); 
    String LiveVersion = "100";

    if(curVer < liveVer) Log.v("setup", "There is a new version");

    }

你可以通過在AnimationSet

// Scaling 
Animation scale = new ScaleAnimation(fromXscale, toXscale, fromYscale, toYscale, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); 
// 1 second duration 
scale.setDuration(1000); 
// Moving up 
Animation slideUp = new TranslateAnimation(fromX, toX, fromY, toY); 
// 1 second duration 
slideUp.setDuration(1000); 
// Animation set to join both scaling and moving 
AnimationSet animSet = new AnimationSet(true); 
animSet.setFillEnabled(true); 
animSet.addAnimation(scale); 
animSet.addAnimation(slideUp); 
// Launching animation set 
logo.startAnimation(animSet);
