我正在做一个例子,将图像从左向右移动,然后自行旋转。我试过使用 AnimationSet 但图像旋转不正确。它在一个循环中移动,而不是它自己。如何解决这个问题?
我想要什么 MainActivity
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AnimationSet set = new AnimationSet(true);
set.setFillAfter(true);
img_animation = (ImageView) findViewById(R.id.imgBanner);
Animation rotation = AnimationUtils.loadAnimation(this, R.anim.rotation);
rotation.setStartOffset(2000);
rotation.setDuration(2000);
TranslateAnimation moveLefttoRight = new TranslateAnimation(0, 200, 0, 0);
moveLefttoRight.setStartOffset(1000);
moveLefttoRight.setDuration(1000);
set.addAnimation(moveLefttoRight);
set.addAnimation(rotation);
img_animation.startAnimation(set);
}
旋转.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromDegrees="0"
android:interpolator="@android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="90" />
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ImageView
android:id="@+id/imgBanner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/banner" />
</RelativeLayout>
任何建议对我都有帮助
