Android可绘制的语音泡沫

Question

我已经找了好几天,找不到任何关于我如何绘制气泡的好的线索,或者在哪里绘制9个补丁图像用作背景.我是一个可怕的艺术家 - 任何人都可以帮忙吗？

我找到的最好的样本在stackoverflow上,但它是用目标c写的

如何在iPhone上绘制"讲话泡泡"？

谢谢

如果您正在创建聊天屏幕,则可能需要实现传入的语音气泡和传出的语音气泡.我是这样做的:

这是我制作的一个简单的讲话泡泡画.希望,它开始朝着正确的方向发展.使用此drawable的视图需要至少70-80dp的高度和类似的最小宽度才能正确显示.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:top="30dp">
        <rotate
            android:fromDegrees="-45"
            android:pivotX="0%"
            android:pivotY="0%"
            android:toDegrees="0" >
            <shape android:shape="rectangle" >
                <solid android:color="#CCC" />
            </shape>
        </rotate>
    </item>
    <item android:left="20dp">
        <shape android:shape="rectangle" >
            <solid android:color="#CCC" />

            <corners android:radius="5dp" />
        </shape>
    </item>

Android Drawables在绘制任何甚至稍微复杂的东西的可用性方面都有很多不足之处.

这个版本看起来像这样:

更新我一直在研究XML语音泡沫,对我的2014解决方案有点不满意.在2018年,我们拥有矢量绘图,可以提供比上述解决方案更好的解决方案.这里有一些更现代的替代品.它们允许诸如小消息和透明度之类的东西

我知道为时已晚。对于那些不想使用9色块图像但想从气泡中投射阴影的人。这是我最接近WhatsApp演讲泡沫的地方。感谢@ toobsco42的回答。

在布局中正确使用填充。我使用了这些值：

<TextView
    android:id="@+id/text_message_incoming"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_speech_bubble_incoming"
    android:lineSpacingExtra="2dp"
    android:paddingLeft="20dp"
    android:paddingTop="4dp"
    android:paddingRight="10dp"
    android:paddingBottom="10dp"
    android:text="Hi, How are you?"
    android:textColor="@color/colorBlack"
    android:textSize="13.5dp"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintWidth_max="wrap"
    app:layout_constraintWidth_percent="0.8" />

我的输出如下所示：

Answer 5

您应该在某种图像编辑器中制作图像，然后用它创建 9 补丁。您可以使用 9 补丁方法设置您想要内容的区域。然后你可以简单地将一个 TextView 的背景设置为你的 9 补丁。看看市场上一款名为 Bnter 的应用程序，它使用语音气泡来显示与您要查找的内容类似的对话。
