Android：如何使小部件在java中全屏显示

Question

我想在 JAVA CODE 中创建一个全屏的RelativeLayout。

在这个RelativeLayout里面，我想要2个ImaveView，一个位于左上方，50个高度和50个重量，另一个位于左上角，并且＃34; match_parent＆＃34 ;

现在我有了：

relativeLayout = new RelativeLayout(this);
    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
            ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.MATCH_PARENT);
    relativeLayout.setLayoutParams(lp);

    im = new ImageView(this);
    im.setLayoutParams(new LayoutParams(50,50));

    im2 = new ImageView(this);
    im2.setScaleType(ImageView.ScaleType.FIT_XY);
    im2.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));

    relativeLayout.addView(im2);
    relativeLayout.addView(im);

但是第一张图片没有显示，第二张图片只显示完整的重量。

这是我想要的图像：

您可以查看此代码吗？

 RelativeLayout relativeLayout = new RelativeLayout(this);
        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT);
        relativeLayout.setLayoutParams(lp);


        ImageView im = new ImageView(this);
        im.setLayoutParams(new RelativeLayout.LayoutParams(50, 50));
        im.setImageResource(R.color.accent);
        ImageView im2 = new ImageView(this);
        im2.setScaleType(ImageView.ScaleType.FIT_XY);
        im2.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
        im2.setImageResource(R.color.orderProcessing);
        relativeLayout.addView(im2);
        relativeLayout.addView(im);
        setContentView(relativeLayout);
