您好,我正在创建聊天应用程序,我需要在其中创建带有文本的弯曲形状 ImageView。我不知道如何提及布局的形状。我附上了需求的截图。

enter image description here

我试过的:

<LinearLayout
android:id="@+id/left_chat"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="top|left"
android:orientation="horizontal"
android:padding="10dp"
android:visibility="visible" >

<LinearLayout

</LinearLayout>
</LinearLayout>

这是我尝试过但无法实现所需设计的屏幕截图。

我放置了圆形 ImageView 但我不知道如何使用这种类型的设计来引入 android。

请建议我如何创建这样的设计。谢谢。

我们必须使用自定义背景和自定义圆圈 ImageView 。

Top Textveiw backgyound : top_text_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="@android:color/holo_blue_bright" />
<corners
android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="5dp"
android:topRightRadius="10dp" />
</shape>

消息文本背景:msg_text_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="@color/list_row_bg" />
<corners android:radius="@dimen/dimen_10" />
</shape>
