Question

我希望通过获取坐标来设置按钮的动画，然后逐个增加或减少它们，以便按钮可以向左移动然后向右移动。

Answer 1

使用TranslateAnimation：

TranslateAnimation animation = new TranslateAnimation(start_x, start_y, end_x, end_y);
animation.setDuration(1000); // duartion in ms
animation.setFillAfter(false);
button.startAnimation(animation);

我不知道你怎么能得到它的位置，button.getTop（）和button.getLeft（）可以工作......

Answer 2

不确定这是否会对您有所帮助，但我遇到了同样的问题，我能够使用这些方法来做到这一点，setTranslationX（float）setTranslationY（float）

你可以像这样使用它

Button button = (button) findViewById(your id); 
button.setTranslationX(a float value);

这里提供了更多信息的http://developer.android.com/reference/android/view/View.html#attr_android:translationX

   Solution for those who are looking for left to right animation)

            TranslateAnimation animation = new TranslateAnimation(0.0f, 0.0f, 0.0f, 1500.0f); // new TranslateAnimation (float fromXDelta,float toXDelta, float fromYDelta, float toYDelta)

               animation.setDuration(1500); // animation duration
                animation.setRepeatCount(1); // animation repeat count
            animation.setFillAfter(false);
                your_view .startAnimation(animation);//your_view for mine is imageView     


Solution for those who are looking for repeated animation(for eg. left to right and right to left)

            TranslateAnimation animation = new TranslateAnimation(0.0f, 0.0f, 0.0f, 1500.0f); // new TranslateAnimation (float fromXDelta,float toXDelta, float fromYDelta, float toYDelta)
                animation.setDuration(1500); // animation duration
                animation.setRepeatCount(4); // animation repeat count
                animation.setRepeatMode(2); // repeat animation (left to right, right to left)

                animation.setFillAfter(true);
                your_view .startAnimation(animation);//your_view for mine is imageView

单击按钮时，图像从左向右移动您也可以将此代码用于片段。

将此代码插入onCreateView中以获取片段或直接使用按钮侦听器。

    View view = inflater.inflate(R.layout.fragment_move,container,false);
    mBtnMove = view.findViewById(R.id.btn_move);
    mImageMove = view.findViewById(R.id.imv_move);
    mBtnMove.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            float start_x_axis = 0; // initialize the axis value start from and end
            float start_y_axis = 1000;
            float end_x_axis = 0;
            float end_y_axis = 0;
            TranslateAnimation animation = new TranslateAnimation(start_x_axis, start_y_axis, end_x_axis, end_y_axis);
            animation.setDuration(2500); // Duration of image to move from left to right
            mImageMove.startAnimation(animation);
        }
    });
  return view;
