1.首先調用使用隱式Intent 獲取本機相機

Intent it = new Intent();
it.setAction(MediaStore.ACTION_IMAGE_CAPTURE);

file = new File(Environment.getExternalStorageDirectory().getPath(), "h"+(++a)+".png");
imageUri = Uri.fromFile(file);
// 以鍵值對的形式告訴系統照片保存的地址，鍵的名稱不能隨便寫
it.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);

// 使用該API，it所對應的Activity銷燬時會回調MainActivity的onActivityResult方法
// 第二個參數就是一個請求碼，當有多個startActivityForResult方法的時候，就在onActivityResult用請求碼判斷是哪個Activity返回的數據
startActivityForResult(it, TAKE_PHOTO);
