可以获取系统的图像文件、调用系统的照相程序、查看图像的缩略图;
可以获取系统的视频文件、调用系统的视频程序、查看视频的缩略图;
可以获取系统的音频文件、调用系统的音频程序、不知有无缩略图。。。
//选择图片—获取系统的图像文件 requestCode 返回的标识
Intent innerIntent = new Intent(Intent.ACTION_GET_CONTENT); //"android.intent.action.GET_CONTENT"
innerIntent.setType(contentType); //查看类型 String IMAGE_UNSPECIFIED = "image/*";
Intent wrapperIntent = Intent.createChooser(innerIntent, null);
((Activity) context).startActivityForResult(wrapperIntent, requestCode);
//视频—获取系统的视频文件
Intent innerIntent = new Intent(Intent.ACTION_GET_CONTENT);
innerIntent.setType(contentType); //String VIDEO_UNSPECIFIED = "video/*";
Intent wrapperIntent = Intent.createChooser(innerIntent, null);
((Activity) context).startActivityForResult(wrapperIntent, requestCode);
//添加音频—获取系统的音频文件
Intent innerIntent = new Intent(Intent.ACTION_GET_CONTENT);
innerIntent.setType(contentType); //String VIDEO_UNSPECIFIED = "video/*";
Intent wrapperIntent = Intent.createChooser(innerIntent, null);
((Activity) context).startActivityForResult(wrapperIntent, requestCode);
//录音—调用系统录音程序,不知这个有没有缩略图?
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(ContentType.AUDIO_AMR); //String AUDIO_AMR = "audio/amr";
intent.setClassName("com.android.soundrecorder",
"com.android.soundrecorder.SoundRecorder");
((Activity) context).startActivityForResult(intent, requestCode);
//拍摄视频—调用系统的录像机—可以查看缩略图的
int durationLimit = getVideoCaptureDurationLimit(); //SystemProperties.getInt("ro.media.enc.lprof.duration", 60);
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
intent.putExtra(MediaStore.EXTRA_SIZE_LIMIT, sizeLimit);
intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, durationLimit);
startActivityForResult(intent, REQUEST_CODE_TAKE_VIDEO);
//拍照--调用系统的的照相机—可以查看缩略图的:REQUEST_CODE_TAKE_PICTURE 为返回的标识
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //"android.media.action.IMAGE_CAPTURE";
intent.putExtra(MediaStore.EXTRA_OUTPUT, Mms.ScrapSpace.CONTENT_URI); // output,Uri.parse("content://mms/scrapSpace");
startActivityForResult(intent, REQUEST_CODE_TAKE_PICTURE); |
