Question

我希望将两个图像从屏幕中间设置为相互对称。如下图所示。

enter image description here

到目前为止，无论我做了什么，现在我只能从左到右动画一幅图像，反之亦然，但现在我想从中间动画它们。

这是我的代码：

b1 = (Button) findViewById(R.id.button1);
        logo = (ImageView) findViewById(R.id.imageView1);

        Display display = getWindowManager().getDefaultDisplay();
        width = display.getWidth();
        final Animation posX = new TranslateAnimation(0, width - 50, 0, 0);
        posX.setDuration(1500);
        posX.setFillAfter(true);

        b1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                logo.startAnimation(posX);
                logo.setVisibility(View.VISIBLE);
            }
        });

            android:contentDescription="@string/hello_world"
            android:src="@drawable/prev_btn" />

        <ImageView

    ImageView img1 = findViewById(R.id.img1);
    ImageView img2 = findViewById(R.id.img2);

        Animation img1_Anim = AnimationUtils.loadAnimation(this,
                R.anim.img1_animation);
        img1_Anim.setAnimationListener(AnimationListener);
        img1.startAnimation(img1_Anim);

Animation img2_Anim = AnimationUtils.loadAnimation(this,
                R.anim.img2_animation);
        img2_Anim.setAnimationListener(AnimationListener);
        img2.startAnimation(img2_Anim);

    private AnimationListener AnimationListener = new AnimationListener() {

            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {


            }
        };
