如何将LinearLayout或RelativeLayout对角分割成两种不同的大小,每种大小都有不同的子视图.上半部分中的ViewPager示例和底部中的不同LinearLayout.
这样的事情:
我怎样才能实现这一目标?请帮忙
解决方法
最简单的方法是用偏斜切割制作背景图像.如果您希望拥有动态布局并且想要真正剪切小部件,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,getWidth(),getHeight(),null,Canvas.ALL_SAVE_FLAG);
super.dispatchDraw(canvas);
paint.setXfermode(pdMode);
path.reset();
path.moveto(0,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);
}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:showIn="@layout/activity_main">
<com.example.marcin.splitlayout.CutLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:scaleType="centerCrop"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/mazda" />
</com.example.marcin.splitlayout.CutLayout>
<TextView
android:layout_margin="16dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Mazda 3" />
</LinearLayout>
顺便说一句.这个东西最近很受欢迎:)
