ImageView in zirkular durch xml
Ich möchte jedes Bild aus meiner ImageView so machen, dass es mit einem Rand kreisförmig ist.
Ich suchte, fand aber keine nützlichen Informationen (alles, was ich ausprobierte, funktionierte nicht).
Wie kann ich dies durch xml erreichen: Eine ImageView mit bestimmten src erstellen und mit einem Rahmen kreisförmig machen?
Sie können einen einfachen Kreis mit weißem Rand und transparenten Inhalt mit Form erstellen.
// res/drawable/circle.xml
<shape xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:innerRadius="0dp"
Android:shape="ring"
Android:thicknessRatio="1.9"
Android:useLevel="false" >
<solid Android:color="@Android:color/transparent" />
<stroke
Android:width="10dp"
Android:color="@Android:color/white" />
</shape>
Erstellen Sie dann eine Ebenenliste, die gezeichnet werden kann, und fügen Sie sie als Hintergrund für Ihre Bildansicht ein.
// res/drawable/img.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:Android="http://schemas.Android.com/apk/res/Android" >
<item Android:drawable="@drawable/ic_launcher"/>
<item Android:drawable="@drawable/circle"/>
</layer-list>
und legen Sie es als Hintergrund für Ihre Bildansicht.
<ImageView
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
Android:background="@drawable/img"/>
Du wirst so etwas haben.
Dies ist der einfachste Weg, den ich entworfen habe. Versuche dies.

compile 'com.Android.support:design:23.1.1'
compile 'com.Android.support:cardview-v7:23.1.1'

Android:layout_alignParentTop="true"
Android:layout_centerHorizontal="true">
</ImageView>
</Android.support.v7.widget.CardView>
Wenn Sie mit Android-Versionen über Lollipop arbeiten
<Android.support.v7.widget.CardView
Android:layout_width="80dp"
Android:layout_height="80dp"
Android:elevation="12dp"
Android:id="@+id/view2"

Android:layout_width="match_parent"

Android:scaleType="centerCrop"/>
</Android.support.v7.widget.CardView>

Die obigen Methoden scheinen nicht zu funktionieren, wenn Sie das src-Attribut verwenden. Was ich getan habe, ist, zwei Bildansichten in einem Frame-Layout so übereinander zu stellen:
<FrameLayout Android:id="@+id/frame"
Android:layout_width="40dp"
Android:layout_height="40dp">
<ImageView Android:id="@+id/pic"
Android:layout_width="40dp"
Android:layout_height="40dp"
Android:src="@drawable/my_picture" />
<ImageView Android:id="@+id/circle_crop"
Android:layout_width="40dp"
Android:layout_height="40dp"
Android:src="@drawable/circle_crop" />
</FrameLayout>
Fügen Sie einfach ein circular_crop.png in Ihren Zeichenordner ein, der die Form Ihrer Bildgröße (in meinem Fall ein Quadrat) mit weißem Hintergrund und einem transparenten Kreis in der Mitte hat. Sie können dieses Bild verwenden, wenn Sie eine quadratische Bildansicht wünschen.
Laden Sie einfach das Bild oben herunter.
Das Folgende ist eine der einfachsten Möglichkeiten, den folgenden Code zu verwenden:

Mit Hilfe von glide library und RoundedBitmapDrawableFactory class ist dies leicht zu erreichen. Möglicherweise müssen Sie ein kreisförmiges Platzhalterbild erstellen.
Gleiten V4:
Glide.with(context).load(url).apply(RequestOptions.circleCropTransform()).into(imageView);
Glide V3:
Glide.with(context)
.load(imgUrl)
.asBitmap()
.placeholder(R.drawable.placeholder)
.error(R.drawable.placeholder)
.into(new BitmapImageViewTarget(imgProfilePicture) {
@Override
protected void setResource(Bitmap resource) {
RoundedBitmapDrawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(),
Bitmap.createScaledBitmap(resource, 50, 50, false));
drawable.setCircular(true);
imgProfilePicture.setImageDrawable(drawable);
}
});
Ich benutze Shape = "Oval" anstelle des "Rings" unten. Es hat für mich gearbeitet. Um das Bild in Grenzen zu halten, verwende ich <padding> und setze <adjustViewBounds> in meinem <ImageView> auf true. Ich habe es mit Bildern mit einer Größe zwischen 50 x 50 px bis zu 200 x 200 px versucht.
Dies wird den Trick tun:
rechteck.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:shape="rectangle">
<solid Android:color="@Android:color/transparent" />
<padding Android:bottom="-14dp" Android:left="-14dp" Android:right="-14dp" Android:top="-14dp" />
</shape>
circle.xml
<shape xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:innerRadius="0dp"
Android:shape="oval"
Android:useLevel="false" >
<solid Android:color="@Android:color/transparent" />
<stroke
Android:width="15dp"
Android:color="@color/verification_contact_background" />
</shape>
profile_image.xml (Die Layerliste)
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:Android="http://schemas.Android.com/apk/res/Android" >
<item Android:drawable="@drawable/rectangle" />
<item Android:drawable="@drawable/circle"/>
</layer-list>
Ihr Layout
<ImageView
Android:id="@+id/profile_image"
Android:layout_width="match_parent"
Android:layout_height="match_parent"
Android:background="@drawable/default_org"
Android:src="@drawable/profile_image"/>
Sie können CardView einfach ohne externe Bibliothek verwenden
<androidx.cardview.widget.CardView
Android:id="@+id/roundCardView"
Android:layout_width="40dp"
Android:layout_height="40dp"
Android:layout_centerHorizontal="true"
Android:elevation="0dp"

Android:layout_height="40dp"

@Jyotman Singh, die Antwort ist sehr gut (für solide Hintergründe), daher möchte ich sie durch das Zeichnen von Vektorbildern verbessern, die für Ihre Anforderungen neu eingefärbt werden können. Außerdem ist es praktisch, da die einteilige Vektorform gut skalierbar ist.
Dies ist die Rechteck-Kreisform (@ drawable/shape_round_profile_pic):

Die Nutzung ist gleich:
<FrameLayout

Android:layout_height="70dp">

Android:layout_width="match_parent"
Android:layout_height="match_parent"
Android:background="@drawable/YOUR_PICTURE" />

Verwenden Sie diese Bibliothek (es gibt eine gute Dokumentation) und fügen Sie Ihr Bild als Hintergrund hinzu.
Tatsächlich können Sie das, was Google über die Unterstützungsbibliothek RoundedBitmapDrawableFactory ( hier und hier ) bietet, verwenden, anstatt eine Drittanbieter-Bibliothek zu verwenden:
Gradle:
implementation 'androidx.appcompat:appcompat:1.0.0-beta01'
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val originalDrawable = ContextCompat.getDrawable(this, R.drawable.avatar_1)!!
val bitmap = convertDrawableToBitmap(originalDrawable)
val drawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
drawable.setAntiAlias(true)
drawable.cornerRadius = Math.max(bitmap.width, bitmap.height) / 2.0f
avatarImageView.setImageDrawable(drawable)
}
companion object {
@JvmStatic
fun convertDrawableToBitmap(drawable: Drawable): Bitmap {
if (drawable is BitmapDrawable)
return drawable.bitmap
// We ask for the bounds if they have been set as they would be most
// correct, then we check we are > 0
val bounds = drawable.bounds
val width = if (!bounds.isEmpty) bounds.width() else drawable.intrinsicWidth
val height = if (!bounds.isEmpty) bounds.height() else drawable.intrinsicHeight
// Now we check we are > 0
val bitmap = Bitmap.createBitmap(if (width <= 0) 1 else width, if (height <= 0) 1 else height,
Bitmap.Config.ARGB_8888)
val canvas = Canvas(bitmap)
drawable.setBounds(0, 0, canvas.width, canvas.height)
drawable.draw(canvas)
return bitmap
}
}
}

Das Ergebnis:
Angenommen, Sie möchten einen Rand darüber hinzufügen, können Sie beispielsweise Folgendes verwenden:
stroke_drawable.xml
<shape xmlns:Android="http://schemas.Android.com/apk/res/Android" Android:shape="oval">
<stroke
Android:width="4dp" Android:color="@Android:color/black"/>
</shape>
Fügen Sie der ImageView in der XML-Layoutdatei Android:foreground="@drawable/stroke_drawable" hinzu, und Sie erhalten Folgendes:
Ich bin mir nicht sicher, wie man Schatten hinzufügt (das funktioniert bei älteren Android-Versionen). Mit FloatingActionButton (aus der "com.google.Android.material: material" -abhängigkeit ) konnte ich die Bitmap nicht ausfüllen, um die FAB selbst zu füllen. Stattdessen könnte es besser sein, wenn es funktioniert.
BEARBEITEN: Wenn Sie einen Höhenunterschied hinzufügen möchten (verfügbar über API 21), können Sie etwas ändern, was ich geschrieben habe:
In der XML-Layoutdatei:
<androidx.appcompat.widget.AppCompatImageView Android:padding="4dp"
Android:id="@+id/avatarImageView" Android:layout_width="100dp" Android:layout_height="100dp" Android:elevation="8dp"
Android:layout_gravity="center" Android:background="@drawable/stroke_drawable" tools:srcCompat="@drawable/avatar_1"/>
CircularShadowViewOutlineProvider.kt
@TargetApi(Build.VERSION_CODES.Lollipop)
class CircularShadowViewOutlineProvider : ViewOutlineProvider() {
override fun getOutline(view: View, outline: Outline) {
val size = Math.max(view.width, view.height)
outline.setRoundRect(0, 0, size, size, size / 2f)
}
}
In Code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Lollipop)
avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()
Ergebnis:
verwenden Sie einfach diesen einfachen Code: Fügen Sie zunächst die Abhängigkeit hinzu:
implementation 'de.hdodenhof:circleimageview:2.2.0'
fügen Sie dann im XML-Layout den folgenden Code hinzu: -
<de.hdodenhof.circleimageview.CircleImageView xmlns:app="http://schemas.Android.com/apk/res-auto"
Android:id="@+id/Imgshaligram"
Android:layout_width="96dp"
Android:layout_height="96dp"

und benutze diese ImageView im Layout wie:

Ich habe eine einfache Lösung. Erstellen Sie ein neues Image-Asset, indem Sie mit der rechten Maustaste auf Ihren Paketnamen klicken und Neu-> Image-Asset auswählen. Geben Sie den Namen (einen beliebigen Namen) und den Pfad (Speicherort des Bildes in Ihrem System) ein. Klicken Sie dann auf Weiter und Fertig stellen. Wenn Sie den Namen des Bildes als 'img' eingeben, wird automatisch ein rundes Bild mit dem Namen 'img_round' im Ordner mipmap erstellt.
Dann mach das:
<ImageView
Android:layout_width="100dp"
Android:layout_height="100dp"
Android:src="@mipmap/img_round"/>
Ihre Vorschau zeigt möglicherweise immer noch ein rechteckiges Bild. Wenn Sie die App jedoch auf Ihrem Gerät ausführen, ist sie rund.
Diese Klasse ist eine benutzerdefinierte kreisförmige Bildansicht mit Schatten, Strich und Sättigung. Mit dieser benutzerdefinierten kreisförmigen Bildansicht können Sie Ihr Bild in kreisförmiger Form mit Radius erstellen. Jungs für Circular Shadow ImageView Keine Notwendigkeit Github diese Klasse ist genug.
