Android实现圆角图片的方法

本文实例为大家分享了Android实现圆角图片的具体代码，供大家参考，具体内容如下

效果图

创建类CustomRoundAngleImageView

public class CustomRoundAngleImageView extends AppCompatImageView { float width, height; public CustomRoundAngleImageView(Context context) {this(context, null);init(context, null); } public CustomRoundAngleImageView(Context context, AttributeSet attrs) {this(context, attrs, 0);init(context, attrs); } public CustomRoundAngleImageView(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);init(context, attrs); } private void init(Context context, AttributeSet attrs) {if (Build.VERSION.SDK_INT < 18) { setLayerType(View.LAYER_TYPE_SOFTWARE, null);} } @Override protected void onLayout(boolean changed, int left, int top, int right, int bottom) {super.onLayout(changed, left, top, right, bottom);width = getWidth();height = getHeight(); } @Override protected void onDraw(Canvas canvas) {if (width >= 20 && height > 20) { Path path = new Path(); //四个圆角 path.moveTo(20, 0); path.lineTo(width - 20, 0); path.quadTo(width, 0, width, 20); path.lineTo(width, height - 20); path.quadTo(width, height, width - 20, height); path.lineTo(20, height); path.quadTo(0, height, 0, height - 20); path.lineTo(0, 20); path.quadTo(0, 0, 20, 0); canvas.clipPath(path);}super.onDraw(canvas); }}

布局代码

<com.example.myapplication.CustomRoundAngleImageView android: android:layout_width='42dp' android:layout_height='42dp' android:layout_marginLeft='16dp' android:layout_marginTop='10dp' android:src='https://www.haobala.com/bcjs/@mipmap/ic_launcher' android:layout_marginBottom='10dp' android:layout_gravity='center' android:scaleType='centerCrop' />
