无法在 Android 应用程序中获取意图附加内容

我正在尝试将额外内容（字符串）放入意图中。我使用 startActivityForResult 和 onActivityResult 在另一侧获取额外内容。

但我不明白为什么它不起作用！这是我的代码：

    buttonCamera.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra("abc", "test");
            startActivityForResult(intent, PHOTO_RESULT);

        }
    }); 

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PHOTO_RESULT) {
        if (resultCode == RESULT_OK) {

            Bundle extras = data.getExtras();
            if (extras != null) {
                String abc = extras.getString("abc");
                Toast.makeText(getApplicationContext(), abc, Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getApplicationContext(), "can't get", Toast.LENGTH_SHORT).show();
            }

        }
    }
}

我总是得到一个空的吐司，所以额外的不为空..但我无法获取字符串..

谢谢！

I'm trying to put extras (string) in an intent. I use startActivityForResult and onActivityResult to get my extras on the other side.

But I can't get why it doesn't works ! Here's my code :

    buttonCamera.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra("abc", "test");
            startActivityForResult(intent, PHOTO_RESULT);

        }
    }); 

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PHOTO_RESULT) {
        if (resultCode == RESULT_OK) {

            Bundle extras = data.getExtras();
            if (extras != null) {
                String abc = extras.getString("abc");
                Toast.makeText(getApplicationContext(), abc, Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getApplicationContext(), "can't get", Toast.LENGTH_SHORT).show();
            }

        }
    }
}

I always get an empty toast, so the extra is not null.. But I cant't get the String..

Thanks !

要告诉相机文件名，您可以使用以下命令：

File mFile = new File(path, filename);
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mFile));
activity.startActivityForResult(intent, TAKE_PHOTO_CODE);

相机活动将获取额外的意图数据，但不会返回“abc”字符串。您无法告诉相机活动返回“abc”以获得结果。你想用这个 abc 字符串做什么？

edit:
To tell the camera the file name you can use this:

File mFile = new File(path, filename);
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mFile));
activity.startActivityForResult(intent, TAKE_PHOTO_CODE);

The camera activity will get your extra intent data, but it won't return that "abc" string. You can't tell the camera activity to return "abc" for results. What are you trying to do with that abc string?
