EditText背景色

Question

I have an Activity that consists only of a huge EditText, full screen.

To match with my app's colours, i changed the background color of the EditText. But although it occupies the whole screen, it only changes the first line. Everytime i press enter i go to a new line and that line gets the background i want.

What propertie can i set in order to do this? I just can't see it!

Answer 1

我将用视图包装EditText并在视图上设置背景色。

Answer 2

为了更改已经带有背景的视图的背景，最好提供自己的图像，然后使用patch9进行适当的调整大小，希望对您有所帮助。

@everyone:

While searching for a solution for this same kind of problem i found this page. While reading the solutions i thought to myself: "There must be a better way to do this, instead of making your own styles and widgetborders, etcetera, etcetera, ....

Therefore, i present to you: the 1 LINE OF CODE SOLUTION!!! No trolling.

<your-widget-component-that-has-a-background-color>.getBackground().setColorFilter(Color.<your-desired-color>, PorterDuff.Mode.MULTIPLY);).

It works like this:

• "getBackground()" fetches the background from the component
• "setColorFilter" will call a filtering on the background image itself
• "Color." determines what color you want to pass onto the filter
• "PorterDuff.Mode." sets the kind of manipulation you would like to do with the given color and the fetched background image. People with knowledge of image editing software (GIMP, Photoshop, ...) might recognise these modes. Basically, each mode has a certain effect on how the color is applied to the background image. to simply "override" the color of the image, while preservind it's gradients, borders and such, use "MULTIPLY"

I haven't profoundly read the PorterDuff class documentation, but honestly, ain't it a powerful bit of code?

With kind regards,
