保存图片到手机内存

方法一：
public void saveFile(Bitmap bm, String fileName)
throws IOException {
File dirFile = new File(ALBUM_PATH);
if (!dirFile.exists()) {
dirFile.mkdir();
}
File myCaptureFile = new File(ALBUM_PATH + fileName);
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(myCaptureFile));
bm.compress(Bitmap.CompressFormat.JPEG, 80, bos);
bos.flush();
bos.close();
}
 
方法二：
////////
public void saveMyBitmap(String bitName, Bitmap mBitmap) throws IOException {
File f = new File("/sdcard/" + bitName + ".png");
f.createNewFile();
FileOutputStream fOut = null;
try {
fOut = new FileOutputStream(f);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
try {
fOut.flush();
} catch (IOException e) {
e.printStackTrace();
}
try {
fOut.close();
} catch (IOException e) {
e.printStackTrace();
}
}
