Create Button with rounded corners in android

问题

I'm trying to create a button which looks as in the image above. Initially my idea was to create a 9 patch and set it as the button background. But since, this is a plain button, i think we can somehow draw this without using any images.

The button background color is #0c0c0c The border color is #1a1a1a The text color is #cccccc

I found a similar question on SO but that creates a gradient -

回答1:

The Android Developer's Guide has a detailed guide on this: Shape Drawbables.

You could also simply remove the gradient element from the link you provided:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="3dp" />
    <stroke android:width="5px" android:color="#1a1a1a" />
</shape>

   <Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/textView1"
    android:layout_alignLeft="@+id/textView1"
    android:layout_marginBottom="56dp"
    android:text="Button" 
    android:textColor="#FF0F13"
    android:background="@drawable/bbkg"/>//create bbkg.xml in drawable folder

bbkg.xml//button background

   <?xml version="1.0" encoding="utf-8"?>
  <selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true" 
    android:drawable="@drawable/pressed" />
  <item  android:state_focused="false" 
    android:drawable="@drawable/normal" />
  </selector>

normal.xml //button background normal state

  <?xml version="1.0" encoding="UTF-8"?> 
  <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"> 
  <solid android:color="#10EB0A"/>    
  <stroke android:width="3dp"

If you want something like this

Button preview

here is the code.

1.Create a xml file in your drawable folder like mybutton.xml and paste the following markup:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
 <item android:state_pressed="true" >
     <shape android:shape="rectangle"  >
         <corners android:radius="3dip" />
         <stroke android:width="1dip" android:color="#5e7974" />
         <gradient android:angle="-90" android:startColor="#345953" android:endColor="#689a92"  />            
     </shape>
 </item>
<item android:state_focused="true">
     <shape android:shape="rectangle"  >
         <corners android:radius="3dip" />
         <stroke android:width="1dip" android:color="#5e7974" />
         <solid android:color="#58857e"/>       
     </shape>
 </item>  
<item >
    <shape android:shape="rectangle"  >
         <corners android:radius="3dip" />
         <stroke android:width="1dip" android:color="#5e7974" />
         <gradient android:angle="-90" android:startColor="#8dbab3" android:endColor="#58857e" />            
     </shape>
 </item>
</selector>

2.Now use this drawable for the background of your view. If the view is button then something like this:

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:textColor="#ffffff"
    android:background="@drawable/mybutton"
    android:text="Buttons" />
