Android 实现图片的圆角，倒影，转换

核心提示：LinearGradient shader = new LinearGradient(0,bitmap.getHeight(), 0, bitmapWithReflection.getHeight()+ reflectionGap, 0x70ffffff, 0x00ffffff, TileMode.CLAMP);pai

LinearGradient shader = new LinearGradient(0,

bitmap.getHeight(), 0, bitmapWithReflection.getHeight()

+ reflectionGap, 0x70ffffff, 0x00ffffff, TileMode.CLAMP);

paint.setShader(shader);

// Set the Transfer mode to be porter duff and destination in

paint.setXfermode(new PorterDuffXfermode(Mode.DST_IN));

// Draw a rectangle using the paint with our linear gradient

canvas.drawRect(0, height, width, bitmapWithReflection.getHeight()

+ reflectionGap, paint);

return bitmapWithReflection;

}

}

修改main.xml布局文件,主要放了两个ImageView控件,代码如下:

Java代码

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:layout_height="wrap_content"
