我试图在图像旋转 30 度的地方得到上面的结果,我试过了
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 Canvas 或代码,或者我应该创建一个 custim ImageView 或其他一些建议吗?

最佳答案
您可以在布局中使用 rotation
属性,如下所示:
<YourView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:rotation="30"/>
