Multiline TextView in Android?

问题

I did like below in xml

<TableRow>
    <TextView android:id=\"@+id/address1\"
        android:layout_width=\"fill_parent\" 
        android:layout_height=\"wrap_content\"
        android:gravity=\"left\"
        android:maxLines=\"4\" 
        android:singleLine=\"false\"              
        android:text=\"Johar Mor, Gulistan-e-Johar, Karachi\" >
    </TextView> 
</TableRow>

It is not working for multiline, and I am using TableLayout...

so what is mistake I am doing here?

回答1:

If the text you're putting in the TextView is short, it will not automatically expand to four lines. If you want the TextView to always have four lines regardless of the length of the text in it, set the android:lines attribute:

<TextView
    android:id="@+id/address1"
    android:gravity="left"
    android:layout_height="fill_parent"
    android:layout_width="wrap_content"
    android:maxLines="4"
    android:lines="4"
    android:text="Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."></TextView>

You can do this with TableRow, see below code

<TableRow >
        <TextView
            android:id="@+id/tv_description_heading"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="left"
            android:padding="8dp"
            android:text="@string/rating_review"
            android:textColor="@color/black"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/tv_description"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="left"
            android:maxLines="4"`enter code here`
            android:padding="8dp"
            android:text="The food test was very good."
            android:textColor="@color/black"
            android:textColorHint="@color/hint_text_color" />
    </TableRow>

I just thought I'd add that if you use :

android:inputType="textMultiLine"

Then the view stops being clickable. I was trying to get multi line textviews in my slide-drawer menu which obviously needs to respond to clicks.

The android:singleLine="false" worked fine though.

回答3:

I like neither of the answers. Simply set the inputType and the TextView will adapt to its content

<TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:inputType="textMultiLine"/>

Tested on a Nexus One (2.3) and Nexus 4 (4.4)

Just add textview in ScrollView

<ScrollView
           android:layout_width="fill_parent"
           android:layout_height="wrap_content"
           android:layout_weight="1"
           android:layout_marginLeft="15dp"
           android:layout_marginRight="15dp"
           android:layout_marginTop="20dp"
           android:fillViewport="true">

           <TextView
               android:id="@+id/txtquestion"
               android:layout_width="fill_parent"
               android:layout_height="match_parent"
               android:background="@drawable/abs__dialog_full_holo_light"
               android:lines="20"
               android:scrollHorizontally="false"
               android:scrollbars="vertical"
               android:textSize="15sp" />

       </ScrollView>

回答5:

Simply put '\n' inside your text... no extra attribute required :)

          <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:text="Pigeon\nControl\nServices"
            android:id="@+id/textView5"
            android:layout_gravity="center"
            android:paddingLeft="12dp"/>

I do not like the solution that forces the number of lines in the text view. I rather suggest you solve it via the solution proposed here. As I see the OP is also struggling with making text view look like proper in table and shrinkColumns is the correct directive to pass in to achieve what is wanted.

回答7:

Try to work with EditText by make it unclickable and unfocusable, also you can display a scrollbar and delete the EditText's underbar.
Here is an example:

<EditText
android:id="@+id/my_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_parent"
android:inputType="textMultiLine"                   <!-- multiline -->
android:clickable="false"                         <!-- unclickable -->
android:focusable="false"                         <!-- unfocusable -->
android:scrollbars="vertical"     <!-- enable scrolling vertically -->
android:background="@android:color/transparent"   <!-- hide the underbar of EditText -->
/>  

Hope this helps :)

First replace "\n" with its Html equavalent "<br>" then call Html.fromHtml() on the string. Follow below steps:

String text= model.getMessageBody().toString().replace("\n", "<br>")
textView.setText(Html.fromHtml(Html.fromHtml(text).toString()))

This works perfectly.

回答9:

you can use android:inputType="textMultiLine"

  <TextView android:id="@+id/address1"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:gravity="left"
    android:maxLines="4" 
    android:inputType="textMultiLine"
    android:text="Johar Mor, Gulistan-e-Johar, Karachi" />

回答10:

What I learned was to add "\n" in between the words where you want it to brake into the next line. For example...

<TextView
    android:id="@+id/time"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAlignment="center"
    android:text="M-F 9am-5pm \n By Appointment Only" />

The \n between 5pm and By allowed me more control of where I wanted my my next line to begin and end.

回答11:

The best answer I found for multiline TextView is:

android:inputType="textMultiLine"

回答12:

I used:

TableLayout tablelayout = (TableLayout) view.findViewById(R.id.table);
tablelayout.setColumnShrinkable(1,true);

it worked for me. 1 is the number of column.

You can do this with TableRow, see below code

<TableRow >
    <TextView
        android:id="@+id/tv_description_heading"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="left"
        android:padding="8dp"
        android:text="@string/rating_review"
        android:textColor="@color/black"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/tv_description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="left"
        android:maxLines="4"`enter code here`
        android:padding="8dp"
        android:text="The food test was very good."
        android:textColor="@color/black"
        android:textColorHint="@color/hint_text_color" />
</TableRow>

回答14:

Why don't you declare a string instead of writing a long lines into the layout file. For this you have to declare a line of code into layout file 'android:text="@string/text"' and go to the \\app\src\main\res\values\strings.xml and add a line of code ' Your multiline text here' Also use '\n' to break the line from any point else the line will automatically be adjusted.

回答15:

for me non of the solutions did not work. I know it is not a complete answer for this question, but sometimes it can help.

I put 4 textviews in a vertical linearlayout.

<Linearlayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation:"vertical"

    ...>
    <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text:"line1"
       .../>
    <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text:"line2"
       .../>
    <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text:"line3"
       .../>
    <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text:"line4"
       .../>
</LinearLayout>

This solution is good for cases that the text view text is constant, like labels.

回答16:

TextView will be multi line when it wont get enough space to fit in the single line and singLine not set to true.

If it gets the space in one line it wont be multi line.
