保存Bitmap到本地文件夹
[方法一]:
/** 保存方法 */
public void saveBitmap() {
Log.e(TAG, "保存图片");
File f = new File("/sdcard/namecard/", picName);
if (f.exists()) {
f.delete();
}
try {
FileOutputStream out = new FileOutputStream(f);
bm.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
Log.i(TAG, "已经保存");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
在这里还需要两个权限:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
[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();
- }
- }
