create a chatView layout in android
提问by thepoosh
I'm creating a chat application and I'm thinking on ways to create the actual chat view.
我正在创建一个聊天应用程序，我正在考虑创建实际聊天视图的方法。
I already have the layout for the chat window itself but I was thinking about how to implement the chat messages.
我已经有了聊天窗口本身的布局，但我正在考虑如何实现聊天消息。
I was thinking of creating a TableLayoutand each row will be the users image and the chat message (or bubble or what not).
我正在考虑创建一个TableLayout，每一行都将是用户图像和聊天消息（或气泡或其他内容）。
Does anyone have an idea on how to design and create these rows?
有没有人知道如何设计和创建这些行？
this is what I did up to now:
这就是我到目前为止所做的：
<?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>
我正在努力实现这种外观

回答by Paresh Mayani
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.
我建议您为 ListView 创建自定义适配器，而不是 TableLayout 。您只需要检查条件即可更改getViews()方法内部布局/视图的背景。
Some thread may be helpful to you:

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