Android：在 TextView 中截取长多行文本

Question

I have a TextView with a height depending on previous content, but there might be a long Text in it. How can I cut it off at the right point and concatenate three dots or something similar to the new end?

Currently it looks like this:

I found some solutions for Single Line Text, but how does it work with more than one line? I also do not know the number of lines, because this depends on the screen size.

Are there other typical ways on Android to show that the text can be extended? Eg a colour gradient in the last line?

Edit:

When I do it without a fixed heigth, I have to make the height depend on the element above and my XML will look like this:

<TextView
   android:id="@+id/podcastShortDesc"
   android:text="Long text"
   android:layout_below="@+id/podcastTitle"
   android:layout_toRightOf="@+id/podcastLogo"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"

   android:maxLines="3"
   android:ellipsize="end"

   android:layout_above="@+id/podcastMoreAction" />

When I do specify maxLines I can have luck an it will work:

But if the title is too big, it does not work:

Answer 1

You should add following code for "3 dots" at the end.

android:ellipsize="end"

You should remove fixed height property

android:layout_height="50dip"

instead you should add number of lines

android:maxLines="4"  
android:layout_height="wrap_content"  

Android will take care everything else. In this way, even if text is smaller than 4 lines, android will take care size. If it is more than 4 lines, it will add "3 dots" :) Specify fixed height may cut your text.

Answer 2

Try this. Hope it will work.

<TextView
android:id="@+id/podcastShortDesc"
android:text="LONG LONG LONG TEXT"
android:layout_width="match_parent"
android:layout_height="50dip"
android:maxHeight="50dp"
android:ellipsize="end"/>

I have tested 50dp can show two line in normal font size. So in 50dp height you should add maxLines 2.

Answer 3

Try this fix layout_height and add scroll in your textview

<TextView
android:id="@+id/text1"
android:layout_width="match_parent"
android:layout_height="50dip"
android:text="Hello......"
android:scrollbars="vertical"/>
