Comment ajouter de l'ombre autour de la circulaire imageview
je veux ajouter de l'ombre autour de l'imageView circulaire.
Voici mon code.
Je veux faire comme cette image
C'est mon .fichier xml
cochez cette image.
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:id="@+id/layoutTop"
android:layout_width="match_parent"
android:layout_height="200dp"
android:background="#355482" >
</RelativeLayout>
<RelativeLayout
android:id="@+id/layoutBottom"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_alignParentBottom="true"
android:layout_below="@+id/layoutTop"
android:background="@drawable/loading" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="113dp"
android:text="Profile"
android:textColor="#355482"
android:textSize="20dp"
android:textStyle="bold" />
</RelativeLayout>
<ImageView
android:id="@+id/overlapImage"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="132dp"
android:adjustViewBounds="true"
android:background="@drawable/round_image"
android:src="@drawable/ic_launcher" />
c'est round_image.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#ffffff" />
<corners android:radius="2dp"/>
<size
android:height="80dp"
android:width="80dp" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
</shape>
j'essaie un code pour l'effet d'ombre mais ça ne marche pas.

j'Espère que cela va vous aider:)
<?xml version="1.0" encoding="utf-8"?>

<solid android:color="@color/gray"/>
<!--shadow Color-->

android:bottom="3dp">
<shape android:shape="oval">
<solid android:color="@color/lightgrey"/>//Background Color
</shape>
</item>
</layer-list>
changez la couleur de fond et la couleur de L'ombre comme vous voulez..

avant de répondre, je veux vous donner un conseil. Vous avez juste à mettre le titre de votre question dans Google. J'ai essayé de chercher comme circulaire imageview avec l'ombre android:
Sans utiliser de Bibliothèque:
Modifier android:color="#BDBDBD"forme balise.
Votre round_image.xml sera de la forme:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#BDBDBD" />
<corners android:radius="2dp"/>
<size
android:height="80dp"
android:width="80dp" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
</shape>
Utilisation De La Bibliothèque:
Avez-vous essayé ce CircularImageView
Vous pouvez utiliser cette bibliothèque ou si vous ne voulez pas utiliser alors obtenez du code de cette bibliothèque interne res dossier.
je vous Remercie.

Créer un circle_shadow.xml file et utilise ce code ça marche bien pour moi. Apporter des modifications le rayon en fonction de votre exigence.
circle_shadow.xml
<!-- Drop Shadow -->
<item>
<shape android:shape="oval">
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<solid android:color="#00CCCCCC" />
<corners android:radius="3dp" />
</shape>
</item>

cette classe est L'Imageview circulaire personnalisée avec l'ombre,la course, la saturation et en utilisant cette ImageView circulaire personnalisée vous pouvez faire votre image en forme circulaire avec le rayon. Les gars de Circular Shadow ImageView N'ont pas besoin de Github cette classe est suffisante. Ajout dynamique de CircularImageView à votre disposition racine.
*Adding Circular ImageView to your layout dynamically*
RelativeLayout rootLayout= (RelativeLayout) findViewById(R.id.rootLayout);
rootLayout.addView(new CircularImageView(this,200,200,imageBitmap));
public CircularImageView(Context context, int width, int height, Bitmap bitmap) {
super(context);
this.context = context;
this.width = width;
this.height = height;
------> here "bitmap" is the square shape(width* width) scaled bitmap ..
this.bitmap = bitmap;
paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
paint3=new Paint();
paint3.setStyle(Paint.Style.STROKE);
paint3.setColor(Color.WHITE);
paint3.setAntiAlias(true);
paintBorder = new Paint();
imagePaint= new Paint();
paintBorder.setColor(Color.WHITE);
paintBorder.setAntiAlias(true);
this.setLayerType(LAYER_TYPE_SOFTWARE, paintBorder);
this.bitmap2 = Bitmap.createScaledBitmap(bitmap, (bitmap.getWidth() - 40), (bitmap.getHeight() - 40), true);
imagePaint.setAntiAlias(true);
invalidate();
}
@Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
Shader b;
if (bitmap3 != null)
b = new BitmapShader(bitmap3, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
else
b = new BitmapShader(bitmap2, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
imagePaint.setShader(b);
canvas.drawBitmap(maskedBitmap(), 20, 20, null);
}
private Bitmap maskedBitmap()
{
Bitmap l1 = Bitmap.createBitmap(width,width, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(l1);
paintBorder.setShadowLayer(radius, x, y, Color.parseColor("#454645"));
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
final RectF rect = new RectF();
rect.set(20, 20, bitmap2.getWidth(), bitmap2.getHeight());
canvas.drawRoundRect(rect, corner_radius, corner_radius, paintBorder);
canvas.drawRoundRect(rect, corner_radius, corner_radius, imagePaint);
if (strokeWidth!=0.0f)
{
paint3.setStrokeWidth(strokeWidth);
canvas.drawRoundRect(rect, corner_radius, corner_radius, paint3);
}
paint.setXfermode(null);
return l1;
}
------> use seekbar here, here you have to pass "0 -- 250" here corner radius will change ..

}

{
int w = src.getWidth();
int h = src.getHeight();
Bitmap bitmapResult =
Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888);
Canvas canvasResult = new Canvas(bitmapResult);

ColorMatrix colorMatrix = new ColorMatrix();
colorMatrix.setSaturation(settingSat);
ColorMatrixColorFilter filter = new ColorMatrixColorFilter(colorMatrix);
paint.setColorFilter(filter);
canvasResult.drawBitmap(src, 0, 0, paint);
return bitmapResult;
}
--------> use seekbar here, here you have to pass "0 -- 2.0f" here saturation will change
public void setSaturation(float sat)
{
System.out.println("qqqqqqqqqq "+sat);
