android - 拍照，然后编辑保存的图片问题！

Question

我对编程非常陌生，正在尝试使用车载摄像头硬件制作应用程序，我的目的是拍照；然后，当您单击保存时，该图片会出现在要编辑的新活动中...我已经寻找了几天关于如何最好地使用相机硬件...有人告诉我startActivity(new Intent( android.provider.MediaStore.ACTION_IMAGE_CAPTURE));接下来会最简单地初始化相机。 ..我已经让相机启动甚至保存图片，但我的问题在于；一旦我在相机上按下保存，相机活动就会重新加载，而不是将保存的图片踢到可以编辑的新活动中......我知道我可能听起来像一个完整的菜鸟，但如果有人理解这一点并且可以帮助我会很感激。

Adam,

In my app I use the following code to Launch the camera:

public void imageFromCamera() {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    mImageFile = new File(Environment.getExternalStorageDirectory()+File.separator+"MyApp",  
            "PIC"+System.currentTimeMillis()+".jpg");
    mSelectedImagePath = mImageFile.getAbsolutePath();
    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mImageFile));
    startActivityForResult(intent, TAKE_PICTURE);
}

This will save the image to the path mSelectedImagePath which is /sdcard/MyApp/<systemtime>.jpg.

Then you capture the return of the IMAGE_CAPTURE intent in onActivityResult and launch your activity to edit the image from there!

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        switch(requestCode) {
        case TAKE_PICTURE:
                    //Launch ImageEdit Activity
            Intent i = new Intent(this, ImageEdit.class);
                    i.putString("imgPath", "mSelectedImagePath");
                    startActivity(i);
            break;
        }
    }
}

Hope this helps!
