安卓，使滚动视图溢出到左边，而不是正确的？ [英] Android, make scrollable view overflow to the left instead of right?

问题描述

我使用的是父视图得到水平滚动就在我的TextView推荐：

I was recommended using a parent view to get horizontal scrolling right in my TextView:

<HorizontalScrollView android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:scrollHorizontally="true"
        android:gravity="center|right"
        android:text="123456789"/>

</HorizontalScrollView>

水平滚动正常工作，但它使内容溢出时，得到超过它的父的宽度正确的：

Horizontal scrolling works fine but it makes the content overflow to the right when it gets longer than it's parent's width:

-------
|123456|7
-------

不过我工作的一个TextView持有数和人数，因为通常靠右对齐，我需要的TextView溢出到对岸。 （你应该向左滚动看到字符串的开头）。

However I'm working on a textview that holds numbers and since numbers are commonly aligned to the right I need the textview to overflow to the opposite side. (you should have to scroll left to see the beginning of the string).

 ------
1|4567|
 ------

我已经试过比重=右和宽度的多种组合，但我不能设法做到这一点。我该如何调整文字的权利，并使其溢出到左侧？

I have tried multiple combinations of gravity="right" and widths but I cannot manage to do it. How can I align the text to the right and make it overflow to the left?

编辑：

我试图这样做，当用户键入：

I tried doing this when the user types:

calc.setText( newNumber );
HorizontalScrollView hsv = (HorizontalScrollView) findViewById(R.id.hsv);
hsv.scrollTo(hsv.getRight(), hsv.getTop());

此滚动到右边每次一个数，然而最新的号码始终留出画面（它像它滚动，然后加入数）。

This scrolls to the right every time the user types a number, however the latest number is always left out of the screen (it's like it scrolled and THEN added the number).

推荐答案

我已经测试code。因此，有两种方法可以解决这个问题 第一个带有滚动条

I have tested the code . So there are two ways to get around this problem First one with ScrollBars

new Handler().postDelayed(new Runnable(){   
@Override
public void run() {
    HorizontalScrollView hsv = (HorizontalScrollView) findViewById(R.id.hsv1);
        hsv.scrollTo(hsv.getRight(), hsv.getTop());
    }       

},100L);

二是没有滚动条

Second one is without scrollBars

 <TextView 
 android:ellipsize="start"   //add this line
 ...
 />
