You could modify it simply like this GradientDrawable bgShape = (GradientDrawable)btn.getBackground(); bgShape.setColor(Color.BLACK);
numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame – df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list(‘ABCD’)) Here – np.random.randint(0,100,size=(100, 4)) – creates an output array of size (100,4) with random integer elements between [0,100) . Demo – import numpy … Read more
It looks like you forgot the prefix on the color attribute. Try <stroke android:width=”2dp” android:color=”#ff00ffff”/>
I don’t think you can do this in XML (at least not in Android), but I’ve found a good solution posted here that looks like it’d be a great help! ShapeDrawable.ShaderFactory sf = new ShapeDrawable.ShaderFactory() { @Override public Shader resize(int width, int height) { LinearGradient lg = new LinearGradient(0, 0, width, height, new int[]{Color.GREEN, Color.GREEN, … Read more

Create rounded_corner.xml in the drawable folder and add the following content, <?xml version=”1.0″ encoding=”utf-8″?> <shape xmlns:android=”http://schemas.android.com/apk/res/android” > <stroke android:width=”1dp” android:color=”@color/common_border_color” /> <solid android:color=”#ffffff” /> <padding android:left=”1dp” android:right=”1dp” android:bottom=”1dp” android:top=”1dp” /> <corners android:radius=”5dp” /> </shape> Set this drawable in the TextView background property like so: android:background=”@drawable/rounded_corner” I hope this is useful for you.
Visual examples help with this kind of question. Boilerplate In order to create a gradient, you create an xml file in res/drawable. I am calling mine my_gradient_drawable.xml: <?xml version=”1.0″ encoding=”utf-8″?> <shape xmlns:android=”http://schemas.android.com/apk/res/android”> <gradient android:type=”linear” android:angle=”0″ android:startColor=”#f6ee19″ android:endColor=”#115ede” /> </shape> You set it to the background of some view. For example: <View android:layout_width=”200dp” android:layout_height=”100dp” android:background=”@drawable/my_gradient_drawable”/> type=”linear” … Read more
