Android屏幕适配的一个另类方法....

关于android手机屏幕适配，我至今没找到一个合适的方法....于是自己想了一个歪招。

原理也比较简单，例如大多手机的标准分辨率是1920 * 1080或1280 * 720

但是遇到1800 * 1080或1184 * 720的就麻烦了（何况有些手机还有虚拟按键状态栏）,其实也简单,把1800当1920来用，1184当1280来用就OK了

使用代码如下：

//宽度默认为null既是全满，在findViewById时去适配，最后得到适配成功的View对象

ImageView img_two = (ImageView) (ScreenUtils.setViewHeight(context, findViewById(R.id.img_two), null, 0.16f);

本人菜鸟，大家有更好的方法，欢迎指点....

/** * View比例适配 * @return */public static View setViewHeight(Context context, final View view, Float width, float height) {   L.i("父类布局："+view.getParent().getClass().toString());   //这里计算了不标准分辨率屏幕，强制把它当作变准的1920或1280的高度来适配，后续需要其他分辨率的话可以再添加   int totalHeight = 0;   if(ScreenUtils.getTotalHeight(context) > 1700 && ScreenUtils.getTotalHeight(context) < 1920) {      totalHeight = 1920;   }else if(ScreenUtils.getTotalHeight(context) > 1100 && ScreenUtils.getTotalHeight(context) < 1280) {      totalHeight = 1280;   } else {      totalHeight = ScreenUtils.getTotalHeight(context);   }   if(width == null) {      if(view.getParent().getClass().toString().equals("class android.widget.LinearLayout")) {         LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(               LinearLayout.LayoutParams.MATCH_PARENT,               (int) (totalHeight * height + 0.5f));         view.setLayoutParams(params);         return view;      }      if(view.getParent().getClass().toString().equals("class android.widget.RelativeLayout")) {         RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(               RelativeLayout.LayoutParams.MATCH_PARENT,               (int) (totalHeight * height + 0.5f));         view.setLayoutParams(params);         return view;      }      if(view.getParent().getClass().toString().equals("class android.widget.FrameLayout")) {         FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(               FrameLayout.LayoutParams.MATCH_PARENT,               (int) (totalHeight * height + 0.5f));         view.setLayoutParams(params);         return view;      }   }else {      if(view.getParent().getClass().toString().equals("class android.widget.LinearLayout")) {         LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(               (int) (ScreenUtils.getScreenWidth(context) * width + 0.5f),               (int) (totalHeight * height + 0.5f));         view.setLayoutParams(params);         return view;      }      if(view.getParent().getClass().toString().equals("class android.widget.RelativeLayout")) {         RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(               (int) (ScreenUtils.getScreenWidth(context) * width + 0.5f),               (int) (totalHeight * height + 0.5f));         view.setLayoutParams(params);         return view;      }      if(view.getParent().getClass().toString().equals("class android.widget.FrameLayout")) {         FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(               (int) (ScreenUtils.getScreenWidth(context) * width + 0.5f),               (int) (totalHeight * height + 0.5f));         view.setLayoutParams(params);         return view;      }   }   return null;}
