Custom button Swift

Default button Swift look very simple.

To change text color, font size, use this

let at=NSMutableAttributedString(string: t, attributes: [NSForegroundColorAttributeName: UIColor.blueColor(), NSFontAttributeName: UIFont(name: "Arial", size: 15.0)!])

       button.setAttributedTitle(at, forState: .Normal)

To bold text

button.font = UIFont.boldSystemFontOfSize(17)

To set background color

button.backgroundColor = hex("#e6e6fa")

Hex function can see here.

To round corner

button.layer.cornerRadius = 20

Change number index to more or less round angle.

To make border, color border.

button.layer.borderColor = hex("#6699cc").CGColor

button.layer.borderWidth = 1

To make 3D button, make a 3D background image with png format. Drag it in to project, then declare an image above viewDidLoad.

let im = UIImage(named: "3Dfloat")

Set background to button like this.

bu1.setBackgroundImage(im, forState: .Normal)

Neutralize TextView, Button Android

We want button can’t click, add this line to below findViewByid.

button.setEnabled(false);

To make it clickable again, change to.

button.setEnabled(true);

To hide button or textview, add this line.

TextView.setVisibility(View.INVISIBLE);

To show it again.

TextView.setVisibility(View.VISIBLE);

To complete remove view.

TextView.setVisibility(View.GONE);

Custom button Android

Normal button android look very simple.

We want round corner button, with border, color as we choose. Let create a xml file name back.xml in folder drawable.

<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle">

<solid android:color="#E6E6FA"/>

<stroke

android:width="1dip"

 android:color="#4b5320" />

<corners android:radius="20dp"/>

</shape>

If don’t like border, remove the stroke, if want thin border, reduce the width value.

Add this line in file xml.

android:background="@drawable/back"

 Button now look like this.

If we want a round button, set width and height=50dp, change corner in file back.xml to

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

If we want button turn green when clicked, create a file name back2.xml in folder drawable.

<?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="20dip" />

    <stroke android:width="0.5dip" android:color="#6699cc" />

 <gradient android:angle="-90" android:startColor="#66ff00" android:endColor="#bcd4e6"  />           

 </shape>

 </item>

<item android:state_focused="true">

  <shape android:shape="rectangle"  >

  <corners android:radius="20dip" />

 <stroke android:width="0.5dip" android:color="#6699cc" />

  <solid android:color="#afeeee"/>      

 </shape>

 </item> 

<item >

 <shape android:shape="rectangle"  >

 <corners android:radius="20dip" />

 <stroke android:width="0.5dip" android:color="#6699cc" />

<gradient android:angle="-90" android:startColor="#E6E6FA" android:endColor="#e6e8fa" />           

</shape>

</item>

</selector>

Set background of button to back2, when you click button, it will look like this.

When put button above another view like imageView, we will want it transparent. Add this line in to xml file.

android:background="@android:color/transparent"

To make 3D button, create an image like this, you can do it in word art.

Copy image in to drawable folder, set background for button.

android:background="@drawable/image"

If you want button with blur color, create a file name bu.xml in drawable.

<?xml version="1.0" encoding="UTF-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"

    android:shape="rectangle" >

    <stroke

        android:width="2dp"

        android:color="#FFFFFFFF" />

    <gradient

        android:angle="225"

        android:endColor="#DD2ECCFA"

        android:startColor="#DD000000" />

    <corners

        android:bottomLeftRadius="7dp"

        android:bottomRightRadius="7dp"

        android:topLeftRadius="7dp"

        android:topRightRadius="7dp" />

</shape>

And set background for button.

android:background="@drawable/bu"

Button now look like this.

If you change file bu.xml to this.

<?xml version="1.0" encoding="utf-8"?>

<layer-listxmlns:android="http://schemas.android.com/apk/res/android">       

    <item>      

        <shape>

            <corners

                android:radius="5dp" />

            <gradient

                android:angle="270"

                android:startColor="#8BB6F5"

                android:centerColor="#DFE8F9"

                android:endColor="#3F83E9"

                android:centerY="0.2"

                android:type="linear"

            />          

        </shape>

    </item>

</layer-list>

Button now look like this.
