Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);拍完照后就可以在onActivityResult(int requestCode, int resultCode, Intent data)中獲取到Bitmap對象了。Bitmap bitmap = (Bitmap) data.getExtras().get("data");

String sdStatus = Environment.getExternalStorageState();
if (!sdStatus.equals(Environment.MEDIA_MOUNTED)) { // 檢測sd是否可用
Log.v("TestFile",
"SD card is not avaiable/writeable right now.");
return;
}

File file = new File("/sdcard/myImage/");
file.mkdirs();// 創建文件夾
String fileName = "/sdcard/myImage/111.jpg";
try {
b = new FileOutputStream(fileName);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把數據寫入文件
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
try {
b.flush();
b.close();
} catch (IOException e) {
e.printStackTrace();
}
}
