1. 图片放在sdcard中,
Bitmap imageBitmap = BitmapFactory.decodeFile(path) (path 是图片的路径,跟目录是/sdcard)
2. 图片在项目的res文件夹下面
//得到application对象
ApplicationInfo appInfo = getApplicationInfo();
//得到该图片的id(name 是该图片的名字,"drawable" 是该图片存放的目录,appInfo.packageName是应用程序的包)
int resID = getResources().getIdentifier(name, "drawable", appInfo.packageName);
//代码如下
public Bitmap getRes(String name) {
ApplicationInfo appInfo = getApplicationInfo();
int resID = getResources().getIdentifier(name, "drawable", appInfo.packageName);
return BitmapFactory.decodeResource(getResources(), resID);
}
3. 图片放在src目录下
String path = "com/xiangmu/test.png"; //图片存放的路径
InputStream is = getClassLoader().getResourceAsStream(path); //得到图片流
4.android中有个Assets目录,这里可以存放只读文件
资源获取的方式为
InputStream is =getResources().getAssets().open(name);
