4 ways to get picture resources on Android

1. Picture in SDcard

Bitmap imagebitmap = bitmapfactory.decodefile (path) (paths are images, and directories are/sdcard)

2. Picture below the Res folder of the project

Get Application Object

ApplicationInfo appInfo = Getapplicationinfo ();

Get the image ID (name is the name of the picture, "Drawable" is the directory where the picture is stored, Appinfo.packagename is the app's package)

int resID = Getresources (). Getidentifier (Name, "drawable", appinfo.packagename);

The code is as follows

Public Bitmap getres (String name) {

ApplicationInfo appInfo = Getapplicationinfo ();

int resID = Getresources (). Getidentifier (Name, "drawable", appinfo.packagename);

Return Bitmapfactory.decoderesource (Getresources (), ResID);

}

3. The image is placed in the SRC directory

String Path = "Com/xiangmu/test.png"; Path of picture storage

InputStream is = getClassLoader (). getResourceAsStream (path); Get picture Stream

There is a assets directory in 4.android, where you can store read-only files

The way resources are obtained is

InputStream is = Getresources (). Getassets (). open (name);
