将图片保存到本地相册

直接复制就行

只能在真机运行
权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.CAMERA"></uses-permission>

保存按钮监听里面：

//保存按钮

btn_save.setOnClickListener(newView.OnClickListener() {

@Override

public voidonClick(View v) {

Toast.makeText(context,"保存",Toast.LENGTH_SHORT).show();

InputStream is =context.getResources().openRawResource(ilist.get(position%ilist.size()));

Bitmap mBitmap = BitmapFactory.decodeStream(is);

File file =newFile("/sdcard/DCIM/camera");

///stystm/DCIM/camera

String str=file.getPath();

//调用保存相册的方法

saveFile(mBitmap,"c.jpg",str,context);

dialog.dismiss();

}

});

//把图片保存在相册中

public static voidsaveFile(Bitmap bm,String fileName,String path,Context context) {

try{

String subForder =SAVE_REAL_PATH+ path;

File foder =newFile(subForder);

if(!foder.exists()) {

foder.mkdirs();

}

File myCaptureFile =newFile(subForder,fileName);

if(!myCaptureFile.exists()) {

myCaptureFile.createNewFile();

}

BufferedOutputStream bos =newBufferedOutputStream(newFileOutputStream(myCaptureFile));

booleancompress = bm.compress(Bitmap.CompressFormat.JPEG,80,bos);

System.out.println("compress = " + compress);

bos.flush();

bos.close();

//发送广播更新相册

Intent intent =newIntent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);

Uri uri = Uri.fromFile(myCaptureFile);

intent.setData(uri);

context.sendBroadcast(intent);

}catch(IOException e) {

e.printStackTrace();

}

}
