Android 裁剪ImageView的左边缘
我试着得到上面图像旋转30度的结果,我试过这个Android 裁剪ImageView的左边缘,android,canvas,imageview,Android,Canvas,Imageview,我试着得到上面图像旋转30度的结果,我试过这个 thumbnailView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { thumbnailView.getViewTreeObserver().removeOnGlo
thumbnailView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
thumbnailView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
thumbnailView.setPivotX(thumbnailView.getWidth() * 8 / 9);
thumbnailView.setPivotY(0);
thumbnailView.setRotation(30);
}
});
不幸的是,这不是我想要的结果,如果有人能指导我如何实现这一点,我将非常感谢通过画布或代码,或者我应该创建一个custim ImageView或其他一些建议

您可以在布局中使用
旋转
属性,如下所示:
<YourView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:rotation="30"/>
好的,那么您应该执行以下操作:
<YourView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:rotation="30"/>
首先,你应该考虑使用约束布局。在那里,您可以轻松地将图像的右侧与布局的左侧对齐。像这样:
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/progress_thumbnail"
android:layout_width="@dimen/view_work_item_image_width"
android:layout_height="wrap_content"
app:srcCompat="@drawable/yourSource"
android:adjustViewBounds="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="parent" />
</android.support.constraint.ConstraintLayout>
看起来有点复杂,但它应该可以工作。只有在xml中是一样的,我需要去掉那个空白哦,我搞错了。那么,是右下角,你想成为旋转的角度点吗?你能提供布局吗?我想图像的右角位于布局的左角,我编辑了这个问题;)Thx,我明天会试试这个;)
