我想知道如何缩放徽标的动画并移动其位置？
我有一个if语句运行一些检查,然后当它完成时,我希望它缩小图像视图(徽标)并将其向上移动.
继承我的布局
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/bg_default" >
<ImageView
android:id="@+id/su_logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="34dp"
android:src="@drawable/su_logo"
android:contentDescription="@string/cd_su_logo"/>
<ImageView
android:id="@+id/su_shirts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:src="@drawable/su_shirts"
android:contentDescription="@string/cd_su_shirts" />
</RelativeLayout>
继承我的java
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";
int liveVer = Integer.parseInt(LiveVersion);
if(curVer < liveVer) Log.v("setup","There is a new version");
else {
//scale animation
}
}
解决方法
您可以通过在AnimationSet中一起应用ScaleAnimation和TranslateAnimation来实现
// Scaling Animation scale = new ScaleAnimation(fromXscale,toXscale,fromYscale,toYscale,Animation.RELATIVE_TO_SELF,0.5f,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);
