Note: I want to set gravity/direction for each line in text view.

How to implement it in android textview.

this is my textview xml code:

    <TextView
        android:id="@+id/textViewContent"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentRight="true"
        android:autoLink="web"
        android:layoutDirection="rtl"
        android:gravity="start"
        android:layout_gravity="start"
        android:text="My Text"
        android:textColor="#000"
        android:textDirection="rtl" />

@AmitVaghela I updated my tittle and explanation about my problem. — Hamidreza Shokouhi, Jul 05 '16 at 12:25
Can you split your text and show English and Persian text parts separately in own `TextViews`? It seems to be the easiest solution IMHO. — artkoenig, Jul 05 '16 at 12:41
@Artjom I use this text view in recycle view, and i think this solution reduce recycle view perforamnce. what's your idea about this? — Hamidreza Shokouhi, Jul 05 '16 at 13:09
I would always prefere an easy solution and optimize it only if it is **significantly** affects the performance. In your case I don't think that using multiple TextViews will have noticeable performance drawback. — artkoenig, Jul 05 '16 at 13:17

What you are looking for is ANY_RTL text direction to be added to your text view

    android:textDirection="anyRtl"

And you will get a result like this:

Conside that it is an API17+ solution.

You can use the attribute of TextView to align text Content.

Allign text to left in the layout

android:gravity="start"

Aliign text to right in the layout.

android:gravity="end"

Use the gravity attribute.

Instead of left/right use start, that was added for rtl support.

I may be wrong but I don't think you can do it on a per line basis. You'll have to add N textviews 1 for each line. – user6547359 Jul 05 '16 at 12:17

use like this

           if (textview.contentEquals("persian")) {
                textview.setGravity(Gravity.START);
            } else if (textview.contentEquals("english")) {
                textview.setGravity(Gravity.END);
            }

I want to set gravity for each line, not to set gravity for textview. – Hamidreza Shokouhi Jul 05 '16 at 12:16
then set gravity to your layout or view, its a same process as textview. – Sagar Chavada Jul 05 '16 at 12:17
suppose your linear layout have 3 line with 3 textview, then just set layout.setGravity(Gravity.start); – Sagar Chavada Jul 05 '16 at 12:20
I have one text view and a dynamic large string that contains English and Persian. if I had a static string, I could use your suggestion. @Sagar Chavada – Hamidreza Shokouhi Jul 05 '16 at 12:24
what do you mean by dynamic or static string – Sagar Chavada Jul 05 '16 at 12:27

I guess you can try to use spannable and the Alignment properties:

Alignment.ALIGN_OPPOSITE (right) and Alignment.ALIGN_NORMAL (left).
