android 工作室中的自定义徽标作为进度条
Custom logo as progress bar in android studio
我想将我的徽标添加为进度条而不是圆角加载。我已经为徽标制作了 xml 文件，任何人都可以帮助我。要加载的徽标颜色是#4F576C

您将使用 AnimationDrawable 而不是 ProgressBar，从原始向量复制并修改为四元向量（如 drawable/phase1.xml ~ drawable/phase4.xml）并将它们列在动画列表中（如drawable/progress.xml)。例如：
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item
android:drawable="@drawable/phase1"
android:duration="100" />
<item
android:drawable="@drawable/phase2"
android:duration="100" />
<item
android:drawable="@drawable/phase3"
android:duration="100" />
<item
android:drawable="@drawable/phase4"
android:duration="100" />
</animation-list>
然后您可以将其加载到 ImageView 中并为其设置动画：
ImageView progress.setImageResource(R.drawable.progress);
((AnimationDrawable) progress.getDrawable()).start();
您的图像有四个部分：大头针和三个圆弧。由于这需要充当进度条，因此您需要一种方法来根据状态单独显示段。 （因为进度条是基于状态的，所以简单的动画是不合适的。）
首先，将每个片段分成一个单独的可绘制文件，然后将所有这些文件组合成一个 Layer List Drawable。
<layer-list>
<item android:drawable="@drawable/meter_pin" />
<item android:drawable="@drawable/meter_bottom_arc" />
<item android:drawable="@drawable/meter_middle_arc" />
<item android:drawable="@drawable/meter_top_arc" />
</layer-list>
现在，您可以单独访问每个图层来设置其 alpha 值。以下代码将查找将上述可绘制对象设置为背景的视图。然后代码将图钉和底部圆弧变为可见，而其他的不可见。
val view = findViewById<View>(R.id.view)
val bg = view.background as LayerDrawable
bg.getDrawable(0).alpha = 255
bg.getDrawable(1).alpha = 255
bg.getDrawable(2).alpha = 0
bg.getDrawable(3).alpha = 0
这会给我们这张图片：
您可以为从不可见到淡化到完全可见的任何组合设置 alpha 值。我会将此代码放入一个单独的 class 中以使其更易于管理，并创建一个 setProgress() 函数来更改其外观。
如果您想以更离散的步骤显示进度，可以使用 Clip Drawable。
