Android TextView multiline has extra space-CodePudding

Multiline TextViews with android:layout_width="wrap_content" automatically take up maximum space as if they become match_parent. Is there any way keep the true wrap_content behavior?

Example xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/rounded_bg"
        android:backgroundTint="@color/colorAccent"
        android:text="Example text"
        android:textAlignment="center"
        android:textColor="#fff"
        android:textSize="28sp" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:background="@drawable/rounded_bg"
        android:backgroundTint="@color/colorAccent"
        android:text="Example text ================"
        android:textAlignment="center"
        android:textColor="#fff"
        android:textSize="28sp" />

    <TextView
        android:layout_width="270dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:background="@drawable/rounded_bg"
        android:backgroundTint="@color/colorAccent"
        android:text="Example text ================"
        android:textAlignment="center"
        android:textColor="#fff"
        android:textSize="28sp" />

</LinearLayout>

How I want it to look

I want to remove the extra space at the left and right ends of the multiline text. The effect can be done if I manually set the layout_width to some specific value like 270dp, but then it becomes arbitrary. I prefer to keep it as wrap_content.

EDIT: The purpose of this is that I want to use a custom background, rounded bg that fits onto the text. I've edited the example xml and the images.

CodePudding user response：

Put this line of code in the textview and test again,

android:inputType="textMultiLine"

also remove gravity center and use textAlignment center, maybe it will work

CodePudding user response：

Try it programmatically in .java file without changing xml file

SpannableString s = new SpannableString("your content");             
s.setSpan(new BackgroundColorSpan(getResources().getColor(R.color.colorAccent)), 0, s.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE);                     
text.setText(s);
