推荐答案

如何启动一个意图无论从画廊或相机或注册到浏览文件系统的任何应用程序中选择图像。

How to launch a single Intent to select images from either the Gallery or the Camera, or any application registered to browse the filesystem.

而不是意图的选项列表创建对话框，它可能更好，以获得进入图形图标和各种照相机的短名称，画廊，甚至第三方使用Intent.createChooser文件系统浏览器的应用程序，如天文，等等。

Rather than creating a Dialog with a list of Intent options, it is much better to use Intent.createChooser in order to get access to the graphical icons and short names of the various 'Camera', 'Gallery' and even Third Party filesystem browser apps such as 'Astro', etc.

本介绍如何使用标准的选择器意图并增加额外的意图了这一点。

This describes how to use the standard chooser-intent and add additional intents to that.

private Uri outputFileUri;

private void openImageIntent() {

// Determine Uri of camera image to save.
final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
root.mkdirs();
final String fname = Utils.getUniqueImageFilename();
final File sdImageMainDirectory = new File(root, fname);
outputFileUri = Uri.fromFile(sdImageMainDirectory);

    // Camera.
    final List<Intent> cameraIntents = new ArrayList<Intent>();
    final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    final PackageManager packageManager = getPackageManager();
    final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
    for(ResolveInfo res : listCam) {
        final String packageName = res.activityInfo.packageName;
        final Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
        intent.setPackage(packageName);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        cameraIntents.add(intent);
    }

    // Filesystem.
    final Intent galleryIntent = new Intent();
    galleryIntent.setType("image/*");
    galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

    // Chooser of filesystem options.
    final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");

    // Add the camera options.
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));

    startActivityForResult(chooserIntent, YOUR_SELECT_PICTURE_REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if(resultCode == RESULT_OK)
    {
        if(requestCode == YOUR_SELECT_PICTURE_REQUEST_CODE)
        {
            final boolean isCamera;
            if(data == null)
            {
                isCamera = true;
            }
            else
            {
                final String action = data.getAction();
                if(action == null)
                {
                    isCamera = false;
                }
                else
                {
                    isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                }
            }

            Uri selectedImageUri;
            if(isCamera)
            {
                selectedImageUri = outputFileUri;
            }
            else
            {
                selectedImageUri = data == null ? null : data.getData();
            }
        }
    }
}
