Android 工作室设置背景色视图

Question

So I have a code

view.setBackground(ResourcesCompat.getColor(getResources(), R.color.blue, null));

And I have an error

error: incompatible types: int cannot be converted to Drawable
                        view.setBackground(ResourcesCompat.getColor(getResources(), R.color.blue, null));

So I have another code

view.setBackground(ContextCompat.getColor(MainActivity.this, android.R.color.blue));

And I have another error

error: cannot find symbol
                        view.setBackground(ContextCompat.getColor(MainActivity.this, android.R.color.blue));

So I have another code

view.setBackground(android.R.color.blue);

and I have another error

error: cannot find symbol
                        view.setBackground(android.R.color.blue);

Please help. I'm drowning in errors
