【问题描述】:
我尝试制作一个 android FAB 动画工具栏。我正在使用这个例子https://github.com/vpaliyX/FAB-Toolbar-Example 来检查它是如何工作的,但我注意到一个奇怪的事情。克隆示例中的 AnimatorSet 类看起来不错,但是当我尝试在我的项目中打开它时,我得到了这个。是执行问题还是导入问题?
package android.animation;
import android.animation.Animator;
import android.animation.TimeInterpolator;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
public final class AnimatorSet extends Animator {
public AnimatorSet() {
throw new RuntimeException("Stub!");
}
public void playTogether(Animator... items) {
throw new RuntimeException("Stub!");
}
public void playTogether(Collection<Animator> items) {
throw new RuntimeException("Stub!");
}
public void playSequentially(Animator... items) {
throw new RuntimeException("Stub!");
}
public void playSequentially(List<Animator> items) {
throw new RuntimeException("Stub!");
}
public ArrayList<Animator> getChildAnimations() {
throw new RuntimeException("Stub!");
}
public void setTarget(Object target) {
throw new RuntimeException("Stub!");
}
public void setInterpolator(TimeInterpolator interpolator) {
throw new RuntimeException("Stub!");
}
public TimeInterpolator getInterpolator() {
throw new RuntimeException("Stub!");
}
public AnimatorSet.Builder play(Animator anim) {
throw new RuntimeException("Stub!");
}
public void cancel() {
throw new RuntimeException("Stub!");
}
public void end() {
throw new RuntimeException("Stub!");
}
public boolean isRunning() {
throw new RuntimeException("Stub!");
}
public boolean isStarted() {
throw new RuntimeException("Stub!");
}
public long getStartDelay() {
throw new RuntimeException("Stub!");
}
public void setStartDelay(long startDelay) {
throw new RuntimeException("Stub!");
}
public long getDuration() {
throw new RuntimeException("Stub!");
}
public AnimatorSet setDuration(long duration) {
throw new RuntimeException("Stub!");
}
public void setupStartValues() {
throw new RuntimeException("Stub!");
}
public void setupEndValues() {
throw new RuntimeException("Stub!");
}
public void pause() {
throw new RuntimeException("Stub!");
}
public void resume() {
throw new RuntimeException("Stub!");
}
public void start() {
throw new RuntimeException("Stub!");
}
public AnimatorSet clone() {
throw new RuntimeException("Stub!");
}
public String toString() {
throw new RuntimeException("Stub!");
}
public long getTotalDuration() {
throw new RuntimeException("Stub!");
}
public class Builder {
Builder() {
throw new RuntimeException("Stub!");
}
public AnimatorSet.Builder with(Animator anim) {
throw new RuntimeException("Stub!");
}
public AnimatorSet.Builder before(Animator anim) {
throw new RuntimeException("Stub!");
}
public AnimatorSet.Builder after(Animator anim) {
throw new RuntimeException("Stub!");
}
public AnimatorSet.Builder after(long delay) {
throw new RuntimeException("Stub!");
}
}
}
【问题讨论】:
-
您的 IDE 正在反编译一个框架类 (
android.animation.AnimatorSet)。真正的实现是在运行时链接的(例如,7.1.1's version)。 -
那么在这种情况下它是正确的吗?奇怪的是,在一个项目中它反编译了类,而在另一个项目中却没有。
-
“奇怪的是,在一个项目中它反编译了类,而在另一个项目中却没有”——您可能没有从 SDK 管理器下载所有 Android 版本的源代码。
