在项目中,我必须在不同的shape中显示个人资料图片和其他图片。我不知道如何创建这样的形状,以及如何在其中显示图像。我也必须在列表视图中放置这种形状。请建议我。
提前致谢。

尝试类似的东西:
profileImageview=[[UIImageView alloc]initWithFrame:CGRectMake(2,10,100,80)];
UIBezierPath *path = [UIBezierPath new];
[path moveToPoint:(CGPoint){0, 0}];
[path addLineToPoint:(CGPoint){100, 0}];
[path addLineToPoint:(CGPoint){70, 80}];
[path addLineToPoint:(CGPoint){0, 80}];
[path addLineToPoint:(CGPoint){0, 0}];
CAShapeLayer *mask = [CAShapeLayer new];
mask.frame = profileImageview.bounds;
mask.path = path.CGPath;
// Mask the imageView's layer with this shape
profileImageview.layer.mask = mask;

根据需要使用bezier路径使用bazie rpaths并创建所需的形状图层,并将其作为子图层添加到图像视图中。
例如圆形imageView代码如下:
UIBezierPath *path = [UIBezierPath bezierPathWithArcCenter:CGPointMake(self.width/2, self.height/2) radius:MIN(self.width, self.height)/2 startAngle:0.0f endAngle:2 * M_PI clockwise:YES];
CAShapeLayer *maskCircularShapeLayer = [CAShapeLayer layer]; maskCircularShapeLayer.path = path.CGPath;
[self.layer addSublayer:maskCircularShapeLayer];

我试过并获得Android的解决方案。我正在分享我所做的一切。
以下是CustomShape类的代码:
public class CustomShape extends View {
Bitmap bitmap;
BitmapShader bitmapShader;
public CustomShape(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public CustomShape(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomShape(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
Paint p = new Paint(Paint.ANTI_ALIAS_FLAG | Paint.FILTER_BITMAP_FLAG);
Path pth = new Path();
pth.moveTo(0, 0);
pth.lineTo(100, 0);
pth.lineTo(70, 100);
pth.lineTo(0, 100);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.ppp);
bitmapShader = new BitmapShader(bitmap, Shader.TileMode.CLAMP,
Shader.TileMode.REPEAT);
p.setShader(bitmapShader);
canvas.drawPath(pth, p);
}
以下是MainActivity.java的代码
public class MainActivity extends Activity {
CustomShape customShape;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_main);
customShape = (CustomShape) findViewById(R.id.customeShape);
}
}
这是布局
<com.example.btndemo.CustomShape
android:id="@+id/customeShape"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
