项目中有个图片在平板电脑中显示特别小的原因，一直苦于没找到原因，也没有平板电脑测试，今天找了个修改分辨率的，编写相关方法终于处理了，记录下比较： if (file.exists()) {
// 如果文件已经存在，直接返回
Drawable drawable = Drawable.createFromPath(savePath);
DisplayMetrics dm = new DisplayMetrics();
//获取手机屏幕分辨率
dm = context.getResources().getDisplayMetrics();
//屏幕实际大小
// int screenWidth = dm.widthPixels;
// int screenHeight = dm.heightPixels;
float density = dm.density;
//图片实际大小
int imgWidth = (int) (drawable.getIntrinsicWidth() *density);
int imgHeight = (int)( drawable.getIntrinsicHeight() * density);
//drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
drawable.setBounds(0, 0, imgWidth,imgHeight);
//}
return drawable;
}没有图片时加载
private void setDrawable(Drawable nDrawable) {
drawable = nDrawable;
//drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
//setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
DisplayMetrics dm = new DisplayMetrics();
//获取手机屏幕分辨率
dm = context.getResources().getDisplayMetrics();
//屏幕实际大小
// int screenWidth = dm.widthPixels;
// int screenHeight = dm.heightPixels;
float density = dm.density;
//图片实际大小
int imgWidth = (int) (drawable.getIntrinsicWidth() *density);
int imgHeight = (int)( drawable.getIntrinsicHeight() * density);
//drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
drawable.setBounds(0, 0, imgWidth,imgHeight);
setBounds(0, 0, imgWidth, imgHeight); //注意加上，不加会出现图片和文字混淆在一起
