如何在关于活动启动的评议中向下方向发展
原标题:How to scroll to bottom in a ScrollView on activity startup

我在一份意见书中展示了一些数据。 关于活动启动(Creod onCreate)问题,我用数据填写了意见书,希望向下游。

我尝试使用getScrollView(ScrollView.FOCUS_DOWN)。 当我把它当作点击行动时,该方法就发挥了作用。

在活动启动时如何向下层传递雕像? 这意味着,在第一次展示时,这种观点已经发展到底。

最佳回答

需要做如下工作:

    getScrollView().post(new Runnable() {

        @Override
        public void run() {
            getScrollView().fullScroll(ScrollView.FOCUS_DOWN);
        }
    });

这样,这种观点首先得到更新,然后向“新的”底线发展。

问题回答

添加以下代码:

final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
scrollview.post(new Runnable() {
    @Override
    public void run() {
        scrollview.fullScroll(ScrollView.FOCUS_DOWN);
    }
});

对我来说,这项工作是:

scrollview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        scrollview.post(new Runnable() {
            public void run() {
                scrollview.fullScroll(View.FOCUS_DOWN);
            }
        });
    }
});

在布局档案中,你可以这样做:

                android:id="@+id/listViewContent"
                android:layout_width="wrap_content"
                android:layout_height="381dp" 
                android:stackFromBottom="true"
                android:transcriptMode="alwaysScroll">
 scrollView.postDelayed(new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    },1000);

引言

    final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
    scrollview.post(new Runnable() {
       @Override
       public void run() {
         scrollview.fullScroll(ScrollView.FOCUS_DOWN);
       }
    });

在你对数据作修改后添加这一单一字句:

yourScrollview.fullScroll(ScrollView.FOCUS_DOWN);

这是这样做的最佳方式。

scrollView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            scrollView.post(new Runnable() {
                @Override
                public void run() {
                    scrollView.fullScroll(View.FOCUS_DOWN);
                }
            });
        }
});

在初步确定贵组织组成部分并填写数据之后。 在您的创建方法中添加这些内容

Runnable runnable=new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    };
    scrollView.post(runnable);
