Android的TranslateAnimation动画 [英] Android TranslateAnimation animation

问题描述

我有一些关于它的按钮，连接与RelativeLayout的屏幕右上角混合复合视图。我想这个观点动画来权当我点击它开 - 关按钮，并在那里停留，直到用户选择/点击的按钮或打开 - 关闭按钮，再点击，然后它应该动画到右，变得不可见。的问题是，它动画至左，然后将其移回到其原始位置！我应该怎么做才能解决这个问题？

I have a compound view mixed by some buttons on it that is attached on top-right corner of screen with RelativeLayout. I want this view to animate to right when I click on "open-close" button on it and stays there until user selects/clicks one of its buttons or clicks again on "open-close" button and then it should animate to right and become invisible. The problem is that it animates to left and then it moves back to its original place! What should I do to solve this problem?

code：

public class AlarmCommandComponent extends LinearLayout {

    ImageButton carOffButton;
    ImageButton carOnButton;
    ImageButton armButton;
    ImageButton disArmButton;
    ImageButton openCloseButton;
    LayoutAnimationController controller;
    Animation animation;

    public AlarmCommandComponent(Context context, AttributeSet attrs) {
        super(context, attrs);
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        inflater.inflate(R.layout.car_alarm_view, this);

        openCloseButton = (ImageButton) findViewById(R.id.alarmOpenCloseButton);

        AnimationSet set = new AnimationSet(true);
        animation = new TranslateAnimation(
                Animation.RELATIVE_TO_SELF, //fromXType 
                0.0f,                       //fromXValue
                Animation.RELATIVE_TO_SELF, //toXType
                -1.0f,                      //toXValue
                Animation.RELATIVE_TO_SELF, //fromYType
                0.0f,                       //fromYValue
                Animation.RELATIVE_TO_SELF, //toYType
                0.0f);                      //toYValue
        animation.setDuration(500);
        set.addAnimation(animation);
        LayoutAnimationController controller = new LayoutAnimationController(set, 0.25f);
        this.setLayoutAnimation(controller);
        this.setPadding(0, 7, 7, 10);
        this.setBackgroundColor(Color.BLACK);

        openCloseButton.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                openCloseButton_onClick(v);
            }
        });
    }

    public void openCloseButton_onClick(View v) {
        this.startAnimation(animation);
    }

}

任何想法？

推荐答案

默认情况下，动画重置对象到初始状态。您需要指定 fillAfter 到真正：

By default, the animation resets the object to the initial state. You need to specify fillAfter to true:

animation.setFillAfter(true);
