Android Custom Rounded Corners imageview_android

No more nonsense to say, directly to everyone paste code.

The Java classes are as follows:

Import Android.content.Context; 
Import Android.content.res.TypedArray; 
Import Android.graphics.Bitmap; 
Import Android.graphics.Bitmap.Config; 
Import Android.graphics.Canvas; 
Import Android.graphics.Color; 
Import Android.graphics.Paint; 
Import Android.graphics.Path; 
Import Android.graphics.PorterDuff; 
Import Android.graphics.PorterDuffXfermode; 
Import Android.graphics.RectF; 
Import Android.util.AttributeSet; 
Import Android.widget.ImageView; 
Import CN.DOTCREATE.TT.R; 
public class Roundangleimageview extends ImageView {private Paint Paint; 
private int roundwidth = 5; 
private int roundheight = 5; 
Private Paint Paint2; 
Public Roundangleimageview (context, AttributeSet attrs, int defstyle) {Super (context, attrs, Defstyle); 
Init (context, attrs); 
Public Roundangleimageview (context, AttributeSet attrs) {Super (context, attrs); 
Init (context, attrs); 
Public Roundangleimageview {Super (context); 
Init (context, NULL); } Private VOID init (Context context, AttributeSet attrs) {if (attrs!= null) {TypedArray a = Context.obtainstyledattributes (Attrs, 
R.styleable.roundangleimageview); 
Roundwidth= a.getdimensionpixelsize (R.styleable.roundangleimageview_roundwidth, roundWidth); 
Roundheight= a.getdimensionpixelsize (R.styleable.roundangleimageview_roundheight, roundHeight); 
}else {Float density = context.getresources (). Getdisplaymetrics (). density; 
Roundwidth = (int) (roundwidth*density); 
Roundheight = (int) (roundheight*density); 
} paint = new paint (); 
Paint.setcolor (Color.White); 
Paint.setantialias (TRUE); 
Paint.setxfermode (New Porterduffxfermode (PorterDuff.Mode.DST_OUT)); 
Paint2 = new Paint (); 
Paint2.setxfermode (NULL); @Override public void Draw (Canvas Canvas) {Bitmap Bitmap = Bitmap.createbitmap (GetWidth (), GetHeight (), config.argb_ 
8888); 
Canvas canvas2 = new Canvas (bitmap); 
Super.draw (CANVAS2); 
Drawliftup (CANVAS2); 
Drawrightup (CANVAS2); 
Drawliftdown (CANVAS2); 
Drawrightdown (CANVAS2); CanVas.drawbitmap (bitmap, 0, 0, Paint2); 
Bitmap.recycle (); 
private void Drawliftup (Canvas Canvas) {Path PATH = new Path (); 
Path.moveto (0, roundheight); 
Path.lineto (0, 0); 
Path.lineto (roundwidth, 0); 
Path.arcto (New RECTF (0, 0, roundwidth*2, roundheight*2),-90,-90); 
Path.close (); 
Canvas.drawpath (path, paint); 
private void Drawliftdown (Canvas Canvas) {Path PATH = new Path (); 
Path.moveto (0, GetHeight ()-roundheight); 
Path.lineto (0, GetHeight ()); 
Path.lineto (Roundwidth, GetHeight ()); 
Path.arcto (New RECTF (0, GetHeight ()-roundheight*2, 0+roundwidth*2, GetHeight ()), 90, 90); 
Path.close (); 
Canvas.drawpath (path, paint); 
private void Drawrightdown (Canvas Canvas) {Path PATH = new Path (); 
Path.moveto (GetWidth ()-roundwidth, getheight ()); 
Path.lineto (GetWidth (), getheight ()); 
Path.lineto (GetWidth (), getheight ()-roundheight); 
Path.arcto (New RECTF (GetWidth ()-roundwidth*2, getheight ()-roundheight*2, getwidth (), GetHeight ()), 0, 90); 
Path.close (); CanVas.drawpath (path, paint); 
private void Drawrightup (Canvas Canvas) {Path PATH = new Path (); 
Path.moveto (GetWidth (), roundheight); 
Path.lineto (getwidth (), 0); 
Path.lineto (GetWidth ()-roundwidth, 0); 
Path.arcto (New RECTF (GetWidth ()-roundwidth*2, 0, GetWidth (), 0+roundheight*2),-90, 90); 
Path.close (); 
Canvas.drawpath (path, paint);  } 
}

Define a Attr.xml file, placed under the values directory, as follows:

<?xml version= "1.0" encoding= "Utf-8"?>
<resources>
<declare-styleable name= " Roundangleimageview ">
<attr name=" Roundwidth "format=" Dimension "/> <attr" name= roundheight "
format= "Dimension"/>
</declare-styleable>
</resources>

Use the example below:

First, declare the name space of the property:

And then write the same as the general definition view:

<cn.dotcreate.tt.ui.roundangleimageview
android:id= "@+id/headiv"
android:layout_width= "75DP
" android:layout_height= "75DP"
android:layout_centervertical= "true"
android:layout_marginleft= "2DP"
app:roundwidth= "10DP"
app:roundheight= "10DP"
android:src= "@drawable/default_head_icon"/>

Effect as shown:

The above code briefly introduces the Android custom rounded corner imageview knowledge, hope this article to share to everybody to be helpful.
