title: How to create multi color gradient drawable with percent per color and custom angle of gradient
body: <p>For example I have this block from CSS:</p>
  
  <pre><code>.Rectangle {
    width: 1000px;
    height: 500px;
    background-image: linear-gradient(60deg, #101010 30%, #151515 20%, #000000);
  }
  </code></pre>
  
  <p>How can I make it on android?
  One more thing. The angle value in GradientDrawable was always 45*x. How can I place it "60"?</p>
  
  <pre><code>&lt;gradient android:angle="45"
                android:startColor="#101010"
                android:centerColor="#151515"
                android:endColor="#000000"
                android:centerX="0.35"
                android:centerY="1"/&gt;
  </code></pre>
