how to wrap text in textview in android

问题:

Does any one know how to wrap text in TextView in Android platform. i.e if the text in textview exceed the screen length it should be displayed in the second line.

I have searched and tried the following:

android:scrollHorizontally="false",
android:inputType="textMultiLine",
android:singleLine="false"

But none work..

Can anyone suggest how can i do it.. i am relatively new to android platform..

回答1:

For me this issue only occurred on Android < 4.0

The combination of parameters I used were:

android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"

The maxLines count seemed to be the random final piece that made my TextView wrap.

回答2:

For the case where the TextView is inside a TableLayout, the solution is to set android:shrinkColumns="1" on the TableLayout. (Replace 1 with the column number the TextView you want to wrap is in. (0-indexed))

AFAICT, no other attributes are needed on the TextView.

For other cases, see the other answers here.

FWIW, I had initially gotten it to sort of work with

 <TextView
   android:id="@+id/inventory_text"
   android:layout_width="fill_parent"
   android:layout_weight="1"
   android:width="0dp"

but that resulted in some extra empty space at the bottom of the Dialog it was all in.

Constraint Layout

<TextView
android:id="@+id/some_textview"
android:layout_width="0dp"
android:layout_height="wrap_content"

app:layout_constraintLeft_toLeftOf="@id/textview_above"
app:layout_constraintRight_toLeftOf="@id/button_to_right"/>

• Ensure your layout width is zero
• left / right constraints are defined
• layout height of wrap_content allows expansion up/down.
• Set android:maxLines="2" to prevent vertical expansion (2 is just an e.g.)
• Ellipses are prob. a good idea with max lines android:ellipsize="end"

---

0dp width allows left/right constraints to determine how wide your widget is.

Setting left/right constraints sets the actual width of your widget, within which your text will wrap.

You must use 2 parameters :

• android:ellipsize="none" : the text is not cut on textview width

• android:scrollHorizontally="false" the text wraps on as many lines as necessary

回答5:

This should fix your problem: android:layout_weight="1".

OK guys the truth is somewhere in the middle cause you have to see the issue from the parent's view and child's. The solution below works ONLY when spinner mode = dialog regardless of Android version (no problem there.. tested it in VD and DesireS with Android =>2.2) :

1. .Set you spinner's(the parent) mode like :

   android:spinnerMode="dialog"  
   

2. Set the textview's(child custom view) properties to :

   android:layout_weight="1"  
   android:ellipsize="none"  
   android:maxLines="100"  
   android:scrollHorizontally="false"
   

I hope this works for you also.

By setting android:maxEms to a given value together with android:layout_weight="1" will cause the TextView to wrap once it reaches the given length of the ems.

回答8:

In Android Studio 2.2.3 under the inputType property there is a property called textMultiLine. Selecting this option sorted out a similar problem for me. I hope that helps.

Use app:breakStrategy="simple" in AppCompatTextView, it will control over paragraph layout.

It has three constant values

• balanced
• high_quality
• simple

Designing in your TextView xml

<android.support.v7.widget.AppCompatTextView
        android:id="@+id/textquestion"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:scrollHorizontally="false"
        android:text="Your Question Display Hear....Your Question Display Hear....Your Question Display Hear....Your Question Display Hear...."
        android:textColor="@android:color/black"
        android:textSize="20sp"
        android:textStyle="bold"
        app:breakStrategy="simple" />

If your current minimum api level is 23 or more then in Coding

yourtextview.setBreakStrategy(Layout.BREAK_STRATEGY_SIMPLE);

You need to add your TextView in a ScrollView with something like this :

<ScrollView android:id="@+id/SCROLL_VIEW"  
android:layout_height="150px"   
android:layout_width="fill_parent">  

<TextView   
   android:id="@+id/TEXT_VIEW"   
   android:layout_height="wrap_content"   
   android:layout_width="wrap_content"   
   android:text="This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header" />  
 </ScrollView>

I am using Android 2.2 and my textview will automatically goto the next line if it exceeds the screen.

If you would like to have the text goto the next line before the end of the screen, just add in (just put in your own dp value). This will be useful if you have a picture on the right of the text.

android:layout_marginRight="52dp"

Strange enough - I created my TextView in Code and it wrapped - despite me not setting anything except standard stuff - but see for yourself:

LinearLayout.LayoutParams childParams = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
            LayoutParams.WRAP_CONTENT);
childParams.setMargins(5, 5, 5, 5);

Label label = new Label(this);
label.setText("This is a testing label This is a testing label This is a testing label This is a testing labelThis is a testing label This is a testing label");
label.setLayoutParams(childParams);

As you can see from the params definition I am using a LinearLayout. The class Label simply extends TextView - not doing anything there except setting the font size and the font color.

When running it in the emulator (API Level 9) it automatically wraps the text across 3 lines.

Try @Guykun's approach and make sure that parents width is not set to wrap content. This is the thing that I was missing.

回答14:

I had the same problem. Following change made it work -

android:layout_width="wrap_content"

The ellipsis, maxLines, or layout_weight - all didn't make any difference. Note - The parent width is also set as wrap_content.

Just was working on a TextView inside a layout inside a RecyclerView. I had text getting cut off, ex, for Read this message, I saw: Read this. I tried setting android:maxLines="2" on the TextView, but nothing changed. However, android:lines="2" resulted in Read this on first line and message on the 2nd.

回答16:

Its actually really easy. Just write : +"\n" wherever you want a wordwrap
