如何为Android中的按钮指定宽度和高度？
我正在开发一个小型 Android 应用程序，其中包含一些从 Java 代码动态创建的方形按钮。我使用 Absolute.LayoutParams 方法为它们提供宽度和高度，但我收到弃用警告。
LayoutParams params = new LayoutParams(width,height, 0, 0);
button.setLayoutParams(params);
我也尝试过：
button.setHeight(height);
button.setWidth(width);
但它不起作用。还有第三种方法可以轻松清洁吗？
先感谢您！
I'm developing a little Android app with some square buttons created dynamically from Java code. I'm using the Absolute.LayoutParams method to give width and height to them, but I get deprecation warnings.
LayoutParams params = new LayoutParams(width,height, 0, 0);
button.setLayoutParams(params);
I tried this too:
button.setHeight(height);
button.setWidth(width);
But it is not working. There is a third way to do it easily and clean?
Thank you in advance!

使用
AbsoluteLayout，您需要使用AbsoluteLayout.LayoutParams，而不是ViewGroup.LayoutParams。另请注意，设置
View宽度和高度的正确方法是通过LayoutParams进行设置。请参阅ViewGroup.LayoutParams和View.getLayoutParams()。您不必像第二个示例中那样手动设置宽度和高度。不过，我强烈建议您使用
RelativeLayout（或LinearLayout等）来实现此功能...AbsoluteLayout已弃用，并且有充分的理由。现在有很多不同的 Android 设备具有不同尺寸的屏幕，AbsoluteLayout无法在所有设备上工作。永远、永远、永远使用AbsoluteLayout总是好的做法:)。Using an
AbsoluteLayout, you need to useAbsoluteLayout.LayoutParams, rather thanViewGroup.LayoutParams.Also note that the proper way to set the width and height of a
Viewis to do so via theLayoutParams. SeeViewGroup.LayoutParamsandView.getLayoutParams(). You shouldn't have to set the width and height manually as you do in your second example.I strongly suggest, however, that you implement this with a
RelativeLayout(orLinearLayout, etc.) instead...AbsoluteLayoutis deprecated, and for very good reason. There are so many different Android devices with different sized screens now,AbsoluteLayoutjust won't work across them all. Never, ever, ever usingAbsoluteLayoutis always good practice :).
