设置相对布局参数 [英] Setting relative layout parameters

问题描述

所以我想给的ImageView添加到我目前的XML设计 - 和它的工作体面。现在我的主要问题是，我似乎无法找到一种方法来设置图像的属性一样需要它显示等。

So I'm trying to add an imageview to my current xml design - and its working decently. Now my main problem is that I cant seem to find a way to set the attributes for the image like where it needs to be displayed etc.

RelativeLayout mRelativeLayout = (RelativeLayout) findViewById(R.id.board);

ImageView i = new ImageView(this);
i.setImageResource(R.drawable.blue_1);
i.setAdjustViewBounds(true);
mRelativeLayout.addView(i);
setContentView(mRelativeLayout);

我想瞎搞与setlayoutparams但得到完全不知道该怎么做了。

I tried messing around with setlayoutparams but got absolutely no clue what to do with it.

推荐答案

您确实有使用类的LayoutParams这样做，高效，方便地：

You actually have to use the class LayoutParams to do that efficiently and easily :

RelativeLayout mRelativeLayout = (RelativeLayout) findViewById(R.id.board);
ImageView i = new ImageView(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(40, 40);
params.leftMargin = 25;
params.topMargin = 25;
i.setImageResource(R.drawable.icon);
i.setAdjustViewBounds(true);
mRelativeLayout.addView(i, params);

这对我的作品，并把我的图标在屏幕的左上角具有指定保证金在屏幕的两侧。
这是否帮助？

This works for me and put my icon in the top left corner of the screen with the specified margin to the sides of the screen. Does that help?
