如何将vector drawable的大小设置为drawableLeft drawable？

Question

我尝试在我的Android应用中使用矢量绘图。我使用过http://android-developers.blogspot.com/2016/02/android-support-library-232.html。但是我需要在drawableLeft中设置矢量drawble。

这是我的矢量绘图

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
    android:viewportHeight="24.0">
<path
    android:fillColor="@color/colorPrimary"
    android:pathData="M12,17c1.1,0 2,-0.9 2,-2s-0.9,-2 -2,-2 -2,0.9 -2,2 0.9,2 2,2zM18,8h-1L17,6c0,-2.76 -2.24,-5 -5,-5S7,3.24 7,6v2L6,8c-1.1,0 -2,0.9 -2,2v10c0,1.1 0.9,2 2,2h12c1.1,0 2,-0.9 2,-2L20,10c0,-1.1 -0.9,-2 -2,-2zM8.9,6c0,-1.71 1.39,-3.1 3.1,-3.1s3.1,1.39 3.1,3.1v2L8.9,8L8.9,6zM18,20L6,20L6,10h12v10z"/>

布局

<android.support.design.widget.TextInputLayout
            android:id="@+id/textInputLayoutPassword"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <EditText
                android:id="@+id/password"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/prompt_password"
                android:imeActionId="@+id/login"
                android:imeActionLabel="@string/action_sign_in_short"
                android:imeOptions="actionUnspecified"
                android:inputType="textPassword"
                android:maxLines="1"
                android:singleLine="true" android:drawableLeft="@drawable/ic_lock" android:drawablePadding="4dp"/>

        </android.support.design.widget.TextInputLayout>

在上面的VectorDrawable文件中，pathdata不正确。它不包含pathdata中的控制字符。出于测试目的，请执行以下操作：

删除ic_lock.xml文件的所有内容。然后将以下代码（复制和粘贴）放入其中。

您必须在TextView的左侧看到多色图像。我在这里测试它，它正在工作。此图像中有九条路径。一两个就足以让你进行测试和调整。

顶部有width，height，viewportWidth和viewportHeight。两种情况下的宽高比应相同。然后保持纵横比。如果增加视口大小，则会导致缩小（图像大小）。你可以调整一下。

希望这有帮助。
