I want to add my logo as a progress bar instead of rounded circle loading. I’ve already made the xml file for the logo, can anyone help me with that. Logo color to load is #4F576C

I want to load from bottom, when it loads the logo should come only to that particular area and rest of the area should be white or I’ll give a faded color. Can anyone help me with this? Thanks in advance.

You would use AnimationDrawable instead of ProgressBar, copy and modify from the original vector to quadruple vectors (like drawable/phase1.xml ~ drawable/phase4.xml) and list them in an animation list (like drawable/progress.xml). For example:

<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>

Then you can load it into an ImageView and animate it:

ImageView progress.setImageResource(R.drawable.progress);
((AnimationDrawable) progress.getDrawable()).start();

Your image has four segments: The pin and three arcs. Since this needs to behave as a progress bar, you will need a method to make the segments appear individually based upon a state. (Because progress bars are state-based, a simple animation will not be suitable.)

First, separate each segment into an individual drawable file and combine all these files into a 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>
```
Now, you can access each layer individual to set its alpha value. The following code will look up a view that has the above drawable set as a background. The code then turns the pin and the bottom arc to be visible and the others invisible.
```
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
```
Which will give us this image:

You can set the alpha values for any combination from invisible to faded to fully visible. I would put this code into a separate class to make it more manageable and create a setProgress() function to change its appearance.

If you want to show the progress in more discrete steps, you can use a Clip Drawable.
