如何使用水平滚动在单行中的文本视图中设置长字符串

actually i have keep one scrollview. Inside that scroll view I set one textview at run time I want to set text in that textview. The string which I'm going to set is some what big in length so i could not get the string in a single line and i can get my string two or three lines. My scroll view layout width size is 250px. I dont want to exceed that size...My expectation is i want to see that string within that scrollview as single line if the string is exceeds the scroll size then it should horizontally scroll in text view. I tried some functions like setting horizontal scroll to scrollview and textview but nothing is work out. Pls help me how to solve this problem.

实际上我保留了一个scrollview。在滚动视图中,我在运行时设置了一个textview,我想在textview中设置文本。我要设置的字符串是一些大的长度,所以我无法将字符串放在一行中,我可以得到我的字符串两三行。我的滚动视图布局宽度大小为250px。我不想超过那个大小...我的期望是我想在滚动视图中看到该字符串作为单行,如果字符串超过滚动大小,那么它应该在文本视图中水平滚动。我尝试了一些功能,比如将水平滚动设置为scrollview和textview,但没有任何结果。请帮我解决这个问题。

you have to use these two Xml attributes in your TextView widget:

您必须在TextView小部件中使用这两个Xml属性:

android:scrollHorizontally="true"

android:singleLine="true"

So your xml layout must contain something like this:

所以你的xml布局必须包含这样的东西:

<TextView
        android:text="Single-line text view that scrolls automatically if the text is too long to fit in the widget" 
        android:singleLine="true" 
        android:ellipsize="marquee"
        android:marqueeRepeatLimit ="marquee_forever"
        android:focusable="true"
        android:focusableInTouchMode="true" 
        android:scrollHorizontally="true"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"/>

you can get the correspondant method for these attributes if you are creating Your TextView with code, refer to TextView documentation :

如果要使用代码创建TextView,可以获取这些属性的对应方法,请参阅TextView文档:

setHorizontallyScrolling(boolean)
setTransformationMethod(TransformationMethod)
setMarqueeRepeatLimit(int)

try this ,,

试试这个 ,,

TextView.setHorizontallyScrolling(true) TextView.setLines(1);

where did you add the textview..Inside scrollview we able to add only one view...

你在哪里添加了textview..Inside scrollview我们只能添加一个视图...

Take TextView and HorizontalScrollView. Just put textview inside the HorizontalScrollView. And yes make sure to mentioned android:singleLine="true" inside the TextView.

使用TextView和HorizontalScrollView。只需将textview放在HorizontalScrollView中。是的,确保在TextView中提到android:singleLine =“true”。

I had the same issue with a TextView inside a table and nothing detailed here solved the fact that it wouldn't scroll horizontally (automatically, which might not be the desired effect from OP, but it's quite unclear).

我在表格中遇到了与TextView相同的问题,这里没有详细说明解决了它不会水平滚动的事实(自动,这可能不是OP所期望的效果,但它还不太清楚)。

While comparing some code that did work, I found out the TextView must be selected for scrolling to start:

在比较一些有效的代码时,我发现必须选择TextView才能开始滚动:

TextView text_view = new TextView(context);
text_view.setLines(1);
text_view.setHorizontallyScrolling(true);
text_view.setMarqueeRepeatLimit(-1);  //  At this point the view is not scrolling!
...
text_view.setSelected(true);          //  Get scrolling to start

Seems crazy, but it works.

看起来很疯狂,但它确实有效。

for me, this one line in the EditText xml was enough:

对我来说,EditText xml中的这一行就足够了:

android:singleLine="true"
