9补丁图像未拉伸

Question

我试图使用9补丁图像来显示这个气球，尽管背景图像似乎没有根据我定义的文本进行拉伸。

我已经设置了内容区域，如图1所示。当前输出如图2所示。

我随时欢迎你的帮助。谢谢。

<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/balloonView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Title this is dummy text, this is dummy text, this is dummy text"
    android:textSize="13dp"
    android:textColor="@android:color/white"
    android:background="@drawable/balloon" />

我用9-patch复制粘贴了你的TextView (作为balloon.9.png添加到res > drawable中)，它工作了。

这是我的布局：

<?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:orientation="vertical"
    android:background="@color/colorPrimary"
    android:padding="50dp">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/balloon"
        android:text="Title this is dummy text, this is dummy text, this is dummy text"
        android:textColor="@android:color/white"
        android:textSize="13dp" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/balloon"
        android:text="Title this is dummy text, this is dummy text, Title this is dummy text, this is dummy text, Title this is dummy text, this is dummy text, Title this is dummy text, this is dummy text, Title this is dummy text, this is dummy text, Title this is dummy text, this is dummy text, Title this is dummy text, this is dummy text, Title this is dummy text, this is dummy text, this is dummy text"
        android:textColor="@android:color/white"
        android:textSize="13dp" />

    <TextView
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:background="@drawable/balloon"
        android:gravity="center"
        android:padding="40dp"
        android:text="Title this is dummy text, this is dummy text, this is dummy text"
        android:textColor="@android:color/white"
        android:textSize="13dp" />

</LinearLayout>

下面是(来自模拟器的)输出：
