How to change the EditText background Tint color in Android?

I am developing an app using Material theme. In my app, I'm having multiple edit texts to get the input from user.
I've divided the screen into two portions:
top portion background color is white background so it showing the default material theme style but
bottom portion I'm using the blue color,
If I'm using the same style in the bottom portion, EditText background tint not visible clearly. So I'm planning to change the background tint color.It supports the lollipop version. I want to show style for below versions also.
How can I do this?

Take a look at this. android.support.v4.graphics.drawable.DrawableCompat#setTint
With this you can set the tint to your EditText.

Give app widget button custom colour with rounded rectangle shape

I've got an app which creates widgets where the user can set the colour of the button's background via a colour picking dialog. However, the only way I can set the button in the remote view to have this colour is by doing this
rv.setInt(R.id.button, "setBackgroundColor", colour);
but this always makes the background a rectangle shape, replacing any previously set background drawable. What I would like to do is have the button as a rounded-corners rectangle shape which can be set to a custom colour. Is this possible, and if so how?

Changing background of dialog button panel

I'm trying to customise the DatePickerDialog so that the background is all white.
If I do
datePickerDialog.setInverseBackgroundForced(true);
the background is white but the panel behind the buttons remains gray.
How do I specify a colour for this panel?

Since DatePickerDialog extends Dialog, you can set the layout and theming that you want, overriding the existing theme. So, you could check about custom dialogs: http://developer.android.com/guide/topics/ui/dialogs.html#CustomDialog

How to Change the Color Behind Android Dialog

I would like to change the color of the dimmed background that surrounds an Android dialog (not the Window background drawable) programmatically. I am using a dialog themed activity. I do not want to dim it, nor blur it.
If you imagine a dialog with three buttons, I would like to have it do something like this:
Click A: background to translucent red
Click B: background to translucent yellow
Click C: background to translucent green

I'm not sure you can change the color of the background. The dimming is controlled by the dimAmount field of the layout for the dialog window (as well as the FLAG_DIM_BEHIND flag). dimAmount is just a float between 0.0 and 1.0 that controls the amount of dimming (transparent to totally opaque). I think it's just an alpha blend of the existing background; there's no control of coloring as far as I've been able to find.

If you're using Activity with Theme.Dialog then you should look into your xml file for layout and then change background color of outermost container.
