How can I show ellipses on my TextView if it is greater than the 1 line?
提问by Sheehan Alam
I have the following Layout which does not work:
我有以下布局不起作用：
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:id="@+id/experienceLayout"
android:background="#ffffff"
android:layout_height="match_parent"
android:paddingLeft="6dp"
android:paddingRight="6dp"
android:paddingBottom="6dp"
android:paddingTop="6dp">
<TextView
android:layout_weight="1"
android:id="@+id/experienceLabel"
android:text="Experience"
android:layout_height="wrap_content"
android:textColor="#000000"
android:layout_width="wrap_content"
android:textStyle="bold">
</TextView>
<TextView
android:id="@+id/experienceTextView"
android:text="TextView"
android:layout_height="wrap_content"
android:textColor="#000000"
android:layout_width="wrap_content"
android:ellipsize="end"
android:lines="1"
android:maxLines="1"
android:singleLine="true"
android:fadeScrollbars="false">
</TextView>
</LinearLayout>

This is a common problem. Try using the following:
这是一个常见的问题。尝试使用以下方法：
android:scrollHorizontally="true"
android:ellipsize="end"
android:maxLines="1"
.............. the scrollHorizontally is the "special sauce" that makes it work.
................. scrollHorizontally 是使它起作用的“特殊调味料”。

This will also make a single line with ellipsise
这也将制作一条带有省略号的线条
android:singleLine="true"

The way it worked for me on multiple devices / APIs was programmatically like this (where tv is your TextView):
它在多个设备/API 上为我工作的方式以编程方式如下（其中 tv 是您的 TextView）：
if (tv.getLineCount() > 1) {
int lineEndIndex = tv.getLayout().getLineEnd(0);
String text = tv.getText().subSequence(0, lineEndIndex - 3) + "\u2026";
tv.setText(text);
}

Use this
用这个
android:ellipsize="end"
android:singleLine="true"
Don't use this without fully aware of what output comes
不要在不完全了解输出结果的情况下使用它
android:ellipsize="end"
android:maxLines="1"
When you use maxlines = 1it will some time truncate most of the characters.
当您使用maxlines = 1它时，它会在一段时间内截断大部分字符。

So all the answers above cater to the requirement that only 1 line and then the ellipsis should appear. However if you want the ellipsis to appear after certain lines of text, then you should use the following:
所以上面的所有答案都满足了只有 1 行然后省略号应该出现的要求。但是，如果您希望省略号出现在某些文本行之后，则应使用以下内容：
android:ellipsize="end"
android:maxLines="2"
android:singleLine="false"
With this the ellipsis will appear only after 2 lines. Note: Its important to have singleLine as false.
这样，省略号只会出现在 2 行之后。注意：将 singleLine 设为 false 很重要。

android:singleLineis deprecated. In my case, I had to get a fixed height for the TextViewand I used the android:linesattribute instead of android:maxLines. I thought this might help someone having the same problem as mine.
android:singleLine已弃用。就我而言，我必须为 获得固定高度，TextView并且我使用了android:lines属性而不是android:maxLines. 我认为这可能会帮助和我有同样问题的人。
android:ellipsize="end"
android:lines="2"
