Android 设置ImageView 宽高

1.在应用启动时获取屏幕宽高

DisplayMetrics metric = new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(metric);int width = metric.widthPixels;     // 屏幕宽度（像素）int height = metric.heightPixels;   // 屏幕高度（像素）

2.设置

iv_specialtyImage.setImageBitmap(btp);LayoutParams ps = iv_specialtyImage.getLayoutParams();ps.width = Global.screen_width;ps.height = Global.screen_height;iv_specialtyImage.setLayoutParams(ps);
