Set background color of TableRow

问题

I try to set the background color of a TableRow. Currently I have this in my XML file:

android:background="@color/buttonBackground" 

and i work great. But when it run

row.setBackgroundColor(R.color.red);

the row disappears. Can someone explain why that is?

回答1:

I believe you need to do:

Resources resource = context.getResources();
row.setBackgroundColor(resource.getColor(R.color.red)

回答2:

You must be missing the alpha value in your color definition. Verify it has 4 bytes, like #FFFFFFFF.

回答3:

You can also try :

row.setBackgroundColor(Color.RED);

This works for me in Android Studio 2.2.3.

Just write: android:background="@android:color/buttonBackground"
