Android button background color

问题

I am trying to set the background color of a button in my app and I am unable to achieve the result that I want...

The color that I am trying to set is holo_green_light(#ff99cc00). In order to do it, I am using setColorFilter(0xff99cc00, PorterDuff.Mode.MULTIPLY);

The color that I get is not the holo_green_light but a mix of lightgrey and holo_green_light.

I have tried using the LightingColorFilter without much success.

Is there a way to do it programatically, so that the button appears like a button and not a flat rectangle with the color that I need.

回答1:

Buttons are more complex than just changing one color...

Android buttons are made using quite a few 9-patches and state drawables. You should take a look at Android Holo Colors to generate those, you would want to select "Color Button" and it will generate the necessary images & xml for you...

This is my way to do custom Button with different color.`

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<stroke android:width="3dp"
        android:color="#80FFFFFF" />

  <corners android:radius="25dp" />

  <gradient android:angle="270"
            android:centerColor="#90150517"
            android:endColor="#90150517"
            android:startColor="#90150517" />
</shape>

This way you set as background.

<Button android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        android:layout_marginBottom="25dp"
        android:layout_centerInParent="true"
        android:background="@drawable/button"/>

回答3:

If you want to keep the general styling (rounded corners etc.) and just change the background color then I use the backgroundTint property

android:backgroundTint="@android:color/holo_green_light"

回答4:

If you don't mind hardcoding it you can do this ~> android:background="#eeeeee" and drop any hex color # you wish.

Looks like this....

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/textView1"
    android:text="@string/ClickMe"
    android:background="#fff"/>

回答5:

Create /res/drawable/button.xml with the following content :

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<!-- you can use any color you want I used here gray color-->
 <solid android:color="#90EE90"/> 
    <corners
     android:bottomRightRadius="3dp"
     android:bottomLeftRadius="3dp"
  android:topLeftRadius="3dp"
  android:topRightRadius="3dp"/>
</shape>

And then you can use the following :

<Button
    android:id="@+id/button_save_prefs"
    android:text="@string/save"
    android:background="@drawable/button"/>

回答6:

No need to be that hardcore.
Try this :

YourButtonObject.setBackground(0xff99cc00);

回答7:

Why not just use setBackgroundColor(getResources().getColor(R.color.holo_light_green))?

Edit: If you want to have something which looks more like an Android button you are going to want to create a gradient and set it as the background. For an example of this, you can check out this question.

回答8:

In order to keep the style, use:

int color = Color.parseColor("#99cc00");
button.getBackground().mutate().setColorFilter(new PorterDuffColorFilter(color, PorterDuff.Mode.SRC));

回答9:

In addition to Mark Proctor's answer:

If you want to keep the default styling, but have a conditional coloring on the button, just set the backgroundTint property like so:

android:backgroundTint="@drawable/styles_mybutton"

Create the associated file /res/drawable/styles_mybutton.xml, then use the following template and change the colors as per your tastes:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Disabled state-->
    <item android:state_enabled="false"
        android:color="@android:color/white">
    </item>
    <!-- Default state-->
    <item
        android:color="#cfc">
    </item>
</selector>
