以编程方式设置扩展ImageView的宽度和高度-android [英] set extended ImageView width and height programatically - android

问题描述

我有一个自定义类，该类可以扩展ImageView，并以编程方式将其放到RelativeLayout上.我希望每个图像都是特定的宽度和高度.我尝试使用LayoutParams和setMaxWidth/setMaxHeight在代码中设置宽度/高度...似乎都不起作用.

I have a custom class that extends ImageView that I'm programatically putting on to a RelativeLayout. I want each one of these images to be a specific width and height. I've tried setting the width/height in code with LayoutParams and with setMaxWidth/setMaxHeight...neither seem to be working.

这是来自该类的构造函数的代码:

Here is the code from the constructor of the class:

LayoutParams p = new LayoutParams(50,67);       
        this.setLayoutParams(p);
        this.setImageResource(WhichImage(wi));
        this.setMaxWidth(50);
        this.setMaxHeight(67);

我已经将对setImageResource()的调用移到了那里所有内容的上方和下方，并且仍默认为我的可绘制对象中的真实图像大小...

I've moved the call to setImageResource() above and below everything there and it still defaults to the true image size in my drawables...

推荐答案

您可能需要告诉ImageView如何缩放.尝试使用 ImageView#setScaleType .

You probably need to tell the ImageView how to scale. Try using ImageView#setScaleType.
