本文实例讲述了Android中简单调用图片、视频、音频、录音和拍照的方法。分享给大家供大家参考，具体如下：
//选择图片 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 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 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 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 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 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);
希望本文所述对大家Android程序设计有所帮助。
