如何在圆形图像视图中添加图标

Question

我有两个圆形图像视图，一个包含个人资料照片，另一个用于相机。以下是我的 XML 文件：

1. Welocome.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg"
    android:orientation="vertical"
    tools:context=".activity.WelcomeActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin40"
        android:text="Welcome to Almachat"
        android:textColor="#ffffff"
        android:textSize="25dp" />

    <FrameLayout
        android:layout_width="220dp"
        android:layout_height="220dp"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin10">

        <com.almabay.almachat.circularImageView.CircularImageView
            android:id="@+id/profilePic"
            android:layout_width="170dp"
            android:layout_height="170dp"
            android:layout_gravity="bottom|center_horizontal" />

        <com.almabay.almachat.circularImageView.CircularImageView
            android:id="@+id/iv_camera"
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:layout_gravity="top|right"
            android:layout_marginTop="@dimen/margin30"
            android:background="@drawable/color"
            />
    </FrameLayout>

    <TextView
        android:id="@+id/txtName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin20"
        android:textColor="#ffffff"
        android:textSize="30sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/txtSomeText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="Some static text will be here"
        android:textColor="#ffffff"
        android:textSize="20sp" />

    <Button
        android:id="@+id/btnContinue"
        android:layout_width="150dp"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin20"
        android:background="#F7AE21"
        android:padding="@dimen/padding20"
        android:text="Continue"
        android:textColor="#ffffff" />
</LinearLayout>

2.color.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval" >
    <gradient
        android:angle="270"
        android:endColor="#F7AE21"
        android:startColor="#F7AE21" />
    <stroke
        android:width="10dp"
        android:color="#F7AE21" ></stroke>
</shape>

这给我以下设计：

我想添加如下图的相机图标：

CircularImageView.java

public class CircularImageView extends ImageView {

    public CircularImageView(Context ctx, AttributeSet attrs) {
        super(ctx, attrs);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }

        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();

        Bitmap roundBitmap = getRoundedCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);
    }

    public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius) {
        Bitmap
                finalBitmap;
        if (bitmap.getWidth() != radius || bitmap.getHeight() != radius)
            finalBitmap = Bitmap.createScaledBitmap(bitmap, radius, radius,
                    false);
        else
            finalBitmap = bitmap;
        Bitmap output = Bitmap.createBitmap(finalBitmap.getWidth(),
                finalBitmap.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
                finalBitmap.getHeight());

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor("#BAB399"));
        canvas.drawCircle(finalBitmap.getWidth() / 2 + 0.7f,
                finalBitmap.getHeight() / 2 + 0.7f,
                finalBitmap.getWidth() / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(finalBitmap, rect, rect, paint);

        return output;
    }
}

如何在圆形图像视图中添加相机图标？如果我在后台设置相机图标，则只显示相机图标。没有圆形图像视图。

使用以下代码后：

<com.almabay.almachat.circularImageView.CircularImageView
    android:id="@+id/iv_camera"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:layout_gravity="top|right"
    android:layout_marginTop="@dimen/margin30"
    android:background="@drawable/color"
    android:src="@drawable/camera" />

我得到以下屏幕：

如何设置图像大小以适应内部 CircularImageView。

Answer 1

您正在使用 Circular ImageView 的库。所以你需要检查是否有任何属性可以在 ImageView 中设置一个图标。无论如何，这是您实现所需行为的方法。您可以添加内部带有相机图标的图像，而不是设置背景颜色。

<com.almabay.almachat.circularImageView.CircularImageView
    android:id="@+id/iv_camera"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:layout_gravity="top|right"
    android:layout_marginTop="@dimen/margin30"
    android:background="@drawable/image_with_camera" />

您可能会尝试获得此行为的另一种方法是将相机图像设置为 src 属性。

<com.almabay.almachat.circularImageView.CircularImageView
    android:id="@+id/iv_camera"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:layout_gravity="top|right"
    android:layout_marginTop="@dimen/margin30"
    android:background="@drawable/color"
    android:padding="5dp"
    android:src="@drawable/image_camera" />

使用这个，来自 melanke answer How to create a circular ImageView in Android?

public class MLRoundedImageView extends ImageView {

public MLRoundedImageView(Context context) {
    super(context);
}

public MLRoundedImageView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public MLRoundedImageView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
protected void onDraw(Canvas canvas) {

    Drawable drawable = getDrawable();

    if (drawable == null) {
        return;
    }

    if (getWidth() == 0 || getHeight() == 0) {
        return;
    }
    Bitmap b = ((BitmapDrawable) drawable).getBitmap();
    Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

    int w = getWidth(), h = getHeight();

    Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
    canvas.drawBitmap(roundBitmap, 0, 0, null);

}

public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
    Bitmap sbmp;

    if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
        float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
        float factor = smallest / radius;
        sbmp = Bitmap.createScaledBitmap(bmp, (int)(bmp.getWidth() / factor), (int)(bmp.getHeight() / factor), false);
    } else {
        sbmp = bmp;
    }

    Bitmap output = Bitmap.createBitmap(radius, radius,
            Config.ARGB_8888);
    Canvas canvas = new Canvas(output);

    final int color = 0xffa19774;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, radius, radius);

    paint.setAntiAlias(true);
    paint.setFilterBitmap(true);
    paint.setDither(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(Color.parseColor("#BAB399"));
    canvas.drawCircle(radius / 2 + 0.7f,
            radius / 2 + 0.7f, radius / 2 + 0.1f, paint);
    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
    canvas.drawBitmap(sbmp, rect, rect, paint);

    return output;
}}

这里逻辑是用frame布局

 <FrameLayout
                    android:layout_width="150dp"
                    android:layout_height="150dp"
                    android:layout_gravity="center"
                    android:layout_marginTop="10dp">

                    <xxx.xxxx.CircleImageView
                        android:id="@+id/profilePic"
                        android:layout_width="150dp"
                        android:layout_height="150dp"
                        android:src="@drawable/male"
                        android:layout_gravity="bottom|center_horizontal" />

                    <xxx.xxx.CircleImageView
                        android:id="@+id/iv_camera"
                        android:layout_width="40dp"
                        android:layout_height="40dp"
                        android:src="@drawable/editfloat"
                        android:layout_gravity="top|right"

                        />
                </FrameLayout>

Answer 6

您可以仅使用单个图像视图来完成此操作。不知道为什么每个人都建议对圆形内的单个相机图像使用两个图像视图。

创建圆形可绘制对象。
现在使用 src 属性将相机图标添加到 imageview。
使用背景属性将圆形可绘制对象添加到同一图像视图。也给它填充，使相机图标与边界几乎没有分离。
