我希望标题部分（添加照片和交叉图像）保持在顶部，其余内容可以滚动。图像显示为SimpleDraweeView。请注意，图像下方有一些元素，但我无法滚动查看它们。

Answer 1

尝试添加：

<ScrollView android:id="@+id/scroll_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"  //change here
    android:fillViewport="true" >  //add this

Answer 2

想出来，这是我自己的错误。我在我的活动中写过这个

scrollView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (activeLocationState.getVisibility() == View.VISIBLE && !TextUtils.isEmpty(currentlocation)) {
                    activeLocationState.setVisibility(View.GONE);
                    afterLocationState.setVisibility(View.VISIBLE);
                    afterLocationText.setText(currentlocation);
                }

                if (activeCaptionState.getVisibility() == View.VISIBLE) {
                    currentCaption = activeCaptionText.getText().toString().trim();
                    if (!TextUtils.isEmpty(currentCaption)) {
                        activeCaptionState.setVisibility(View.GONE);
                        afterCaptionState.setVisibility(View.VISIBLE);
                        afterCaptionText.setText(currentCaption);
                    }
                }

                return true;
            }
        });

这消耗了所有触摸事件。为解决此问题，我将触控逻辑移至LinearLayout内的ScrollView。

如果内容的高度等于屏幕高度，则ScrollView不会滚动
