使用不同的子视图对角拆分布局的自定义视图
Custom view that splits layout diagonally with different child views
我怎样才能将 LinearLayout
或 RelativeLayout
对角线分成两个不同的大小,每个都有不同的子视图。示例 ViewPager
在上半部分和不同的 LinearLayout
在下半部分。
像这样:
我怎样才能做到这一点?请帮忙
最简单的方法是只用那个倾斜的切口制作背景图像。如果你希望有一个动态布局并且你想真正地剪切小部件,请使用 Canvas.saveLayer/restore。像这样:
private Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
private Xfermode pdMode = new PorterDuffXfermode(PorterDuff.Mode.CLEAR);
private Path path = new Path();
protected void dispatchDraw(Canvas canvas) {
int saveCount = canvas.saveLayer(0, 0, getWidth(), getHeight(), null, Canvas.ALL_SAVE_FLAG);
super.dispatchDraw(canvas);
paint.setXfermode(pdMode);
path.reset();
path.moveTo(0, getHeight());
path.lineTo(getWidth(), getHeight());
path.lineTo(getWidth(), getHeight() - TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 50, getResources().getDisplayMetrics()));
path.close();
canvas.drawPath(path, paint);
canvas.restoreToCount(saveCount);
paint.setXfermode(null);
}

顺便说一句。这个东西最近很流行:)
您也可以尝试叠加底部背景并旋转它。也许您还必须在 x 方向上缩放它以避免在侧面剪裁。
我想我回答这个问题有点晚了,但是你应该看到 this amazing tutorial。
它很简单,没有任何外部库。
输出将类似于:
您需要添加layer-list
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/colorPrimary"/>
<item>
<bitmap android:src="@drawable/bebe" android:gravity="center" android:alpha="0.1"/>
</item>
<item android:top="300dp"
android:bottom="-300dp"
android:left="0dp"
android:right="-300dp">
<rotate
android:fromDegrees="-10"
android:pivotX="0%"
android:pivotY="100%">
<shape
android:shape="rectangle">
<solid
android:color="?android:colorBackground"/>
</shape>
</rotate>

</layer-list>
