小米系统相册是真的坑

系统相册做兼容性测试的时候，遇到神坑手机Redmi Note4。

先上调用的代码：

//调用相册
 private void go2Gallery() {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("image/*");
        try {
            startActivityForResult(intent, PICK_IMAGE_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }

在其他手机都能正确的打开相册，但是在这个手机会出现下面这个截图

然后点击相册，没有任何反应，看了log也没有任何的报错，然后就开始各种百度使用了下面的调用方式：

//调用相册
 private void go2Gallery() {
        Intent intent = new Intent();
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        intent.setType("image/*");
        if (Build.VERSION.SDK_INT < 19) {
            intent.setAction(Intent.ACTION_GET_CONTENT);
        } else {
            intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
        }
        try {
            startActivityForResult(intent, PICK_IMAGE_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }

怀着即将解决的心情，打开测试手机，尼玛这次直接打开的是个树形的文件管理器。内心奔溃中，差点怀疑人生。然后对比了前面的两个方法，无非就是intent的action不一样，然后就接着百度终于还有一个action叫做Intent.ACTION_PICK。然后换了下面的代码：

//调用相册
  private void go2Gallery() {
        Intent intent = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        try {
            startActivityForResult(intent, PICK_IMAGE_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }

哎呀妈呀，终于成了，然后又试了试其它的手机，包括6.0,7.0的Android手机，都正常。问题总算是解决了。

下面是完整的代码，仅供参考~

//调用系统相机
 private void doTakePhoto() {
        mCurrentPhotoFile = new File(yourpath);
        if (!mCurrentPhotoFile.exists()) {
            try {
                mCurrentPhotoFile.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE, null);
        intent.putExtra(MediaStore.EXTRA_OUTPUT,
                Uri.fromFile(mCurrentPhotoFile));
        try {
            startActivityForResult(intent, CAMERA_WITH_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }
