android 调用系统录像，录音等

1、调用系统拍照
[mw_shl_code=java,true]Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
//保存到指定目录
File file = new File("/mnt/sdcard/picture");
if (!file.exists()) {
file.mkdirs();
}
File out = new File("/mnt/sdcard/picture/123.jpg");
Uri uri = Uri.fromFile(out);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, 0);[/mw_shl_code]

2、调用系统录音
[mw_shl_code=java,true]
Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
startActivityForResult(intent, 1);[/mw_shl_code]

3、调用系统录像
[mw_shl_code=java,true]Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0.5);//画质0.5
intent.putExtra(android.provider.MediaStore.EXTRA_SIZE_LIMIT,768000);
intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 70000);//70s
File file = new File("/mnt/sdcard/video");
if (!file.exists()) {
file.mkdirs();
}
File tmpFile = new File("/mnt/sdcard/video/123.mp4");
Uri outputFileUri = Uri.fromFile(tmpFile);
// 设置视频的品质为高
mIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
// 设置视频文件名
mIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(mIntent, 2);[/mw_shl_code]
4、直接打开图库
[mw_shl_code=java,true]Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);[/mw_shl_code]

5、打开图库和文件夹选项
[mw_shl_code=java,true] Intent intent = new Intent();intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, PIC);[/mw_shl_code]
