Android 输入框弹起时顶起布局(与ScrollView一起使用)

        
        scrollView1为布局文件中ScrollView的id
        // 监听键盘弹起或关闭(ScrollView)
        scrollView1.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(final View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                if (oldBottom != 0 && bottom != 0 && (oldBottom - bottom > 100)) {
//                    Toast.makeText(getApplicationContext(), "监听到软键盘弹起...", Toast.LENGTH_SHORT).show();
//                    scrollView.fullScroll(ScrollView.FOCUS_DOWN);(会导致输入框失去焦点)
                    // 获得屏幕
                    View decorView = getWindow().getDecorView();
                    ViewUtil.scrollToBottom(decorView, v);
                } else if (oldBottom != 0 && bottom != 0 && (bottom - oldBottom > 100)) {
//                    Toast.makeText(getApplicationContext(), "监听到软件盘关闭...", Toast.LENGTH_SHORT).show();
                }
            }
        });

                return;
            }
            int offset = decorView.getMeasuredHeight() - scroll.getHeight();
            if (offset < 0) {
                offset = 0;
