Android：如何调整图像大小以自动适应视图

我有 png 楼层地图图像。我使用下面的代码来设置默认图像大小以适合视图。

imageView 是我的 ImageSwitcher 中的视图：

imageView.setImageMatrix(createDefaultMatrix());

private Matrix createDefaultMatrix() {
    Matrix matrix = new Matrix();
    matrix.setValues(new float[]{1.136f, 0.0f, -17.204117f,0.0f, 1.136f, 66.24078f,0.0f, 0.0f, 1.0f});
    matrix.postScale(1.1085271f, 1.1085271f, 198.08646f, 304.4192f);
    return matrix;
}

如果您注意到了，我使用固定值只是为了使图像与视图相匹配。

任何关于如何根据其视图自动安装它的指导都是值得赞赏的。

I have png floor map images. I am using the below code to set the default image size to fit with the view.

imageView is the view inside my ImageSwitcher:

imageView.setImageMatrix(createDefaultMatrix());

private Matrix createDefaultMatrix() {
    Matrix matrix = new Matrix();
    matrix.setValues(new float[]{1.136f, 0.0f, -17.204117f,0.0f, 1.136f, 66.24078f,0.0f, 0.0f, 1.0f});
    matrix.postScale(1.1085271f, 1.1085271f, 198.08646f, 304.4192f);
    return matrix;
}

If you have notice, I am using fix values just to fit the image with the view.

Any guidance on how to do it automatically fitted against its View is appreciated.
