android调用系统的图片,视频，音频，录音，拍照

//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(MediaStore.Audio.Media.RECORD_SOUND_ACTION); startActivityForResult(intent, 0);

　　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);

//获取路径

Uri uri = data.getData();

String[] filePathColumn = { MediaStore.Audio.Media.DATA };

Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);

cursor.moveToFirst();

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

audioPath = cursor.getString(columnIndex);

cursor.close();

调用系统图库看图片

Intent intent = new Intent();

intent.setAction(android.content.Intent.ACTION_VIEW);

intent.setDataAndType(Uri.fromFile(file), "image/*");

startActivity(intent);
