create a chatView layout in android-ThrowExceptions

Exception or error:

I’m creating a chat application and I’m thinking on ways to create the actual chat view.

I already have the layout for the chat window itself but I was thinking about how to implement the chat messages.

I was thinking of creating a TableLayout and each row will be the users image and the chat message (or bubble or what not).

Does anyone have an idea on how to design and create these rows?

this is what I did up to now:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/background_light"
    android:orientation="vertical"
    android:weightSum="10" >

    <ScrollView
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_weight="1" >

        <TableLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:stretchColumns="1" >

            <TableRow
                android:id="@+id/tableRow1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >

                <!-- insert chat message here !-->

            </TableRow>

            <View
                android:layout_height="2dip"
                android:background="#000" />

            <TableRow
                android:id="@+id/tableRow2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >

                 <!-- next chat message --!>

            </TableRow>
        </TableLayout>
    </ScrollView>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:layout_weight="9"
        android:orientation="horizontal" >

        <EditText
            android:id="@+id/chatLine"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:hint="Say:"
            android:imeOptions="actionSend"
            android:singleLine="true" />
    </LinearLayout>

</LinearLayout>

and I’m trying to achieve a this look the desired chat view

How to solve:

How about below code –

Main.xml

<LinearLayout android:id="@+id/list_layout"
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent"
    android:background="@drawable/background"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <ListView android:id="@+id/myList" 
        android:layout_height="fill_parent"
        android:layout_width="wrap_content"/>

</LinearLayout>

list_row_layout_even.xml

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

    <ImageView android:id="@+id/user_img"
        android:layout_height="wrap_content" 
        android:layout_width="wrap_content"
        android:layout_marginTop="80dip"
        android:src="@drawable/sample_image"/>

    <ImageView android:id="@+id/even_bubble"
        android:layout_height="wrap_content" 
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_margin="5dip"
        android:src="@drawable/even"/>

    <TextView android:id="@+id/text" 
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"
        android:textColor="#000000" 
        android:textSize="16dip"
        android:layout_marginRight="8dip"
        android:layout_marginLeft="120dip"
        android:layout_marginTop="10dip" />

</RelativeLayout>

list_row_layout_odd.xml

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

    <ImageView android:id="@+id/user_img"
        android:layout_height="wrap_content" 
        android:layout_width="wrap_content"
        android:layout_marginTop="80dip"
        android:layout_alignParentRight="true"
        android:src="@drawable/sample_image"/>

    <ImageView android:id="@+id/odd_bubble"
        android:layout_height="wrap_content" 
        android:layout_width="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_margin="5dip"
        android:src="@drawable/odd"/>

    <TextView android:id="@+id/text" 
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_alignParentLeft="true"
        android:textColor="#ffffff" 
        android:textSize="16dip"
        android:layout_marginRight="120dip"
        android:layout_marginLeft="8dip"
        android:layout_marginTop="10dip" />

</RelativeLayout>

This is my output –

Just Customize this example with your needs.

Instead of TableLayout, i would suggest you to create Custom adapter for ListView. You just need to check the condition to change the background of layout/views inside getViews() method.

use it like this, in your activity

    ListView listMsg; 
    ArrayList<Msg> listMessages;
    MessagesListAdapter adapter;
    listMessages = new ArrayList<Msg>();

    listMessages.add(new Msg(cle,email,message,attach....));
    adapter = new MessagesListAdapter(this, listMessages);
    listMsg.setAdapter(adapter);
