RelativeLayout not responding on TextView

Question

I have a ListView with RelativeLayout, refer below:

MainActivity.java

adapter = new ArrayAdapter<String>(this, R.layout.listviewitemtext, sortedmessage){
        public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
            View row = convertView;
        TextView text1 = (TextView) view.findViewById(id.msgThread);
            String msgBody=msgThread.getItemAtPosition(position).toString();
            char lastChar=msgBody.charAt(msgBody.length()-1);
            if( lastChar=='1'){
                text1.setText(msgBody.substring(0, msgBody.length() - 1));
                text1.setBackgroundResource(drawable.incoming_bubble_telegram);
                text1.setTextColor(Color.BLACK);
                text1.setPadding(60,60,60,60);
            }
            else if( lastChar=='0'){
                text1.setText(msgBody.substring(0, msgBody.length() - 1));
                text1.setBackgroundResource(drawable.outgoing_bubble_telegram_selected);
                text1.setTextColor(Color.WHITE);
                text1.setPadding(60, 60, 60, 60);

            }
        return view;

    };};
    msgThread.setAdapter(adapter);`

main_activity.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    tools:context="com.example.clyde.listviewtest.MessageThread">

    <ListView
        android:layout_width="fill_parent"
        android:layout_height="500dp"
        android:id="@+id/msgList"
        android:divider="@android:color/transparent"
        android:stackFromBottom="true"
        android:transcriptMode="alwaysScroll"
        android:background="#FFFFFF"
        />
</RelativeLayout>

listviewitemtext.xml

<TextView
        android:id="@+id/msgThread"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:maxWidth="1000px"
        android:layout_alignParentRight="true"
 />

What I want to achieve is align the textview on the right. layout_alignParentRight doesn't seem to work. And when I use RelativeLayout on my TextView my app crashes/not responding. Any help would be much appreciated.

Note: Please take note that Listview is styled in the MainActivity.xml, and TextView is styled in a separate xml file (listviewitems.xml). I apply this listviewitems.xml as a custom layout in my adapter.

can you tell for the purpose of xmlns:android="http://schemas.android.com/apk/res/android" in TextView — Mohammad Tauqir, Aug 29 '15 at 12:36
you want the textView in the Listview or in the relativeLayout? — bendaf, Aug 29 '15 at 12:37
@bendaf my textView is populated as items on my ListView using an adapter. And I want them to float right. I googled and searched on stackoverflow and someone suggested to use RelativeLayout in order for the android:layout_alignParentRight to work. — Clyde Winux, Aug 29 '15 at 12:39
I think you should use the RelativLayout outside of the TextView not the ListView :). I will write my answer... — bendaf, Aug 29 '15 at 12:40
oh, yes you have to make an own ArrayAdapter for this, like in this post: http://stackoverflow.com/a/15832564/3162918 I will search if there is an easier solution for this — bendaf, Aug 29 '15 at 13:00
@bendaf I included the code on my main java file. Please check it. :) — Clyde Winux, Aug 29 '15 at 13:04

If you want just the gravity of the textView right than you can use the standard ArrayAdapter and here is your answer:

<TextView
    android:id="@+id/msgThread"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:maxWidth="1000px"
    android:gravity="right"/>

If you want the TextView's width to wrap_content than you should create a new ArrayAdapter and an own layout for your list item like in this post. I will write here just the difference, your row.xml should be like:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/msgThread"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:maxWidth="1000px"
        android:layout_alignParentRight="true"
        android:gravity="right"/>
</RelativeLayout>

It's still crashes. Please take note that Listview is styled in the MainActivity.xml, and TextView is styled in a separate xml file (listviewitems.xml). I apply this listviewitems.xml as a custom layout in my adapter. – Clyde Winux Aug 29 '15 at 12:49
I see, what is the stacktrace? Could you share it and your initialization code also? – bendaf Aug 29 '15 at 12:53
gravity will only set the alignment of the text and since the TextView's layout_width is wrap_content because I am using an image background. I just want the TextView to float right. – Clyde Winux Aug 29 '15 at 13:16
Ok I will complete my answer – bendaf Aug 29 '15 at 13:18
