我想让任何图像从我的ImageView是圆形的边界。
我搜索了一下,但没有找到任何有用的信息(我尝试的任何方法都不管用)。
如何通过XML实现这一点: 创建一个ImageView与某些src,并使它与边界圆形?

当前回答
这样就可以了:
rectangle.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(图层列表)
<?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>
你的布局
<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"/>
其他回答
我希望这对你有所帮助。
1) 可塑性图像视图
<com.google.android.material.imageview.ShapeableImageView
android:layout_width="250dp"
android:layout_height="250dp"
android:padding="5dp"
app:strokeWidth="10dp"
app:strokeColor="@android:color/darker_gray"
app:shapeAppearanceOverlay="@style/circleImageView"
android:src="@drawable/profile"
android:layout_margin="10dp"/>
Style add here: res/values/styles.xml
<style name="circleImageView" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">50%</item>
</style>

2) 圆图像视图
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="@drawable/profile"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"/>
别忘了实现:Gradle Scripts > build。gradle (Module: app) >依赖项
implementation 'de.hdodenhof:circleimageview:3.1.0'
完整的描述请查看这里:来源在这里。
3) 循环图像视图
<com.mikhaellopez.circularimageview.CircularImageView
android:layout_width="250dp"
android:layout_height="250dp"
android:src="@drawable/image"
app:civ_border_color="#3f51b5"
app:civ_border_width="4dp"
app:civ_shadow="true"
app:civ_shadow_radius="10"
app:civ_shadow_color="#3f51b5"/>
别忘了实现:Gradle Scripts > build。gradle (Module: app) >依赖项
implementation 'com.mikhaellopez:circularimageview:4.3.1'
完整的描述请查看这里:来源在这里。
创建一个CustomImageview,然后简单地覆盖它的onDraw()方法如下:
@Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
如果你想要的代码自定义小部件以及:-
CircularImageView.java
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Path;
import android.graphics.RectF;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
import androidx.annotation.Nullable;
public class CircularImageView extends ImageView {
private Drawable image;
public CircularImageView(Context context) {
super(context);
init(null, 0);
}
public CircularImageView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
init(attrs, 0);
}
public CircularImageView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs, defStyleAttr);
}
@Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
private void init(AttributeSet attrs, int defStyle) {
TypedArray a = Utils.CONTEXT.getTheme().obtainStyledAttributes(attrs, R.styleable.CircularImageView, 0, 0);
try {
image = a.getDrawable(R.styleable.CircularImageView_src);
} finally {
a.recycle();
}
this.setImageDrawable(image);
}
}
此外,在res/attrs.xml中添加以下代码来创建所需的属性
<declare-styleable name="CircularImageView">
<attr name="src" format="reference" />
</declare-styleable>
试试这个。
public class RoundedImageView extends android.support.v7.widget.AppCompatImageView {
private int borderWidth = 4;
private int viewWidth;
private int viewHeight;
private Bitmap image;
private Paint paint;
private Paint paintBorder;
private BitmapShader shader;
public RoundedImageView(Context context)
{
super(context);
setup();
}
public RoundedImageView(Context context, AttributeSet attrs)
{
super(context, attrs);
setup();
}
public RoundedImageView(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
setup();
}
private void setup()
{
paint = new Paint();
paint.setAntiAlias(true);
paintBorder = new Paint();
setBorderColor(Color.WHITE);
paintBorder.setAntiAlias(true);
this.setLayerType(LAYER_TYPE_SOFTWARE, paintBorder);
paintBorder.setShadowLayer(4.0f, 0.0f, 2.0f, Color.WHITE);
}
public void setBorderWidth(int borderWidth)
{
this.borderWidth = borderWidth;
this.invalidate();
}
public void setBorderColor(int borderColor)
{
if (paintBorder != null)
paintBorder.setColor(borderColor);
this.invalidate();
}
private void loadBitmap()
{
BitmapDrawable bitmapDrawable = (BitmapDrawable) this.getDrawable();
if (bitmapDrawable != null)
image = bitmapDrawable.getBitmap();
}
@SuppressLint("DrawAllocation")
@Override
public void onDraw(Canvas canvas)
{
loadBitmap();
if (image != null)
{
shader = new BitmapShader(Bitmap.createScaledBitmap(image, canvas.getWidth(), canvas.getHeight(), false), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
paint.setShader(shader);
int circleCenter = viewWidth / 2;
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter + borderWidth - 4.0f, paintBorder);
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter - 4.0f, paint);
}
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
int width = measureWidth(widthMeasureSpec);
int height = measureHeight(heightMeasureSpec, widthMeasureSpec);
viewWidth = width - (borderWidth * 2);
viewHeight = height - (borderWidth * 2);
setMeasuredDimension(width, height);
}
private int measureWidth(int measureSpec)
{
int result = 0;
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
if (specMode == MeasureSpec.EXACTLY)
{
result = specSize;
}
else
{
// Measure the text
result = viewWidth;
}
return result;
}
private int measureHeight(int measureSpecHeight, int measureSpecWidth)
{
int result = 0;
int specMode = MeasureSpec.getMode(measureSpecHeight);
int specSize = MeasureSpec.getSize(measureSpecHeight);
if (specMode == MeasureSpec.EXACTLY)
{
result = specSize;
}
else
{
result = viewHeight;
}
return (result + 2);
}
}
然后在布局中使用这个ImageView:
<com.app.Demo.RoundedImageView
android:id="@+id/iv_profileImage"
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_centerHorizontal="true"
/>
if you want to set edit icon on to circle imageview than put this below code.
<FrameLayout
android:layout_width="@dimen/_100sdp"
android:layout_height="@dimen/_100sdp"
android:layout_gravity="center"
android:layout_marginTop="10dp">
<de.hdodenhof.circleimageview.CircleImageView
android:id="@+id/profilePic"
android:layout_width="@dimen/_100sdp"
android:layout_height="@dimen/_100sdp"
android:layout_gravity="bottom|center_horizontal"
android:src="@drawable/ic_upload" />
<de.hdodenhof.circleimageview.CircleImageView
android:id="@+id/iv_camera"
android:layout_width="@dimen/_30sdp"
android:layout_height="@dimen/_30sdp"
android:layout_gravity="top|right"
android:src="@drawable/edit"/>
</FrameLayout>
