从Android的意图打开多媒体应用程序 [英] Open gallery app from Android Intent

问题描述

我正在寻找一种方法来打开从意图安卓图库应用程序。

I'm looking for a way to open the Android gallery application from an intent.

我不想回的图片，而是只要打开库，让用户在使用它，如果他们选择了它从启动（浏览图片/文件夹）

I do not want to return a picture, but rather just open the gallery to allow the user to use it as if they selected it from the launcher (View pictures/folders).

我试图做到以下几点：

Intent intent = new Intent();  
intent.setAction(android.content.Intent.ACTION_GET_CONTENT);  
intent.setType("image/*");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

然而，这是导致应用程序关闭一旦我选择照片（我知道这是因为 ACTION_GET_CONTENT ），但我只是需要打开画廊。

However this is causing the application to close once I select a picture (I know this is because of the ACTION_GET_CONTENT), but I need to just open the gallery.

任何帮助将是巨大的。

感谢

推荐答案

我希望这会帮助你。这code对我的作品。

I hope this will help you. This code works for me.

Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
 startActivityForResult(i, RESULT_LOAD_IMAGE);

结果code用于选定的图像更新为画廊查看的

if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
            && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };
        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);

        if (cursor == null || cursor.getCount() < 1) {
            return; // no cursor or no record. DO YOUR ERROR HANDLING
        }

        cursor.moveToFirst();
        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

        if(columnIndex < 0) // no column index
            return; // DO YOUR ERROR HANDLING

        String picturePath = cursor.getString(columnIndex);

        cursor.close(); // close cursor

        photo = decodeFilePath(picturePath.toString());

        List<Bitmap> bitmap = new ArrayList<Bitmap>();
        bitmap.add(photo);
        ImageAdapter imageAdapter = new ImageAdapter(
                AddIncidentScreen.this, bitmap);
        imageAdapter.notifyDataSetChanged();
        newTagImage.setAdapter(imageAdapter);
    }
