代码中设置View

 layout = (FrameLayout) findViewById(R.id.framelayout);        //移除所有的view        //layout.removeAllViews();        //计算出屏幕的宽和高        int screen_w = getResources().getDisplayMetrics().widthPixels;        int screen_h = getResources().getDisplayMetrics().heightPixels;        image1 = new ImageView(Recycle.this);        //设置View的属性        FrameLayout.LayoutParams params1 = new FrameLayout.LayoutParams(screen_w/2,screen_h/2);        image1.setLayoutParams(params1);        image1.setImageResource(R.mipmap.banner_a);        layout.addView(image1);        image2 = new ImageView(Recycle.this);        FrameLayout.LayoutParams params2 = new FrameLayout.LayoutParams(screen_w/2,screen_h/2);        params2.leftMargin = screen_w/8;        image2.setLayoutParams(params2);        image2.setImageResource(R.mipmap.banner_b);        layout.addView(image2);
