Android 调用系统相册选取视频,过滤视频(兼容小米)

老规矩先上图,注:我这个是其他类型设备的样式图,小米也一样的

由于小米手机可能对很多地方不见让,当然对调用系统相机时也跟其他设备不太一

样,一般情况下他都是底下弹出一个框,选取是否进入相册或者文件夹

下面就来贴一下代码

这是在选取相册选取视频的页面

                      if(PhoneInfo.isMIUI()){//是否是小米设备,是的话用到弹窗选取入口的方法去选取视频
                            Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                            intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"video/*");
                            startActivityForResult(Intent.createChooser(intent, "选择要导入的视频"), REQUEST_CODE_PICK);
                        }else{//直接跳到系统相册去选取视频
                            Intent intent = new Intent();
                            if (Build.VERSION.SDK_INT < 19) {
                                intent.setAction(Intent.ACTION_GET_CONTENT);
                                intent.setType("video/*");
                            } else {
                                intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
                                intent.addCategory(Intent.CATEGORY_OPENABLE);
                                intent.setType("video/*");
                            }
                            startActivityForResult(Intent.createChooser(intent, "选择要导入的视频"), REQUEST_CODE_PICK);
                        }

我们写一下在相册选取视频之后的回调

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == REQUEST_CODE_PICK && resultCode == RESULT_OK) {//从相册选取视频
            String videoPath = GetPathFromUri.getPath(this, data.getData());
            initVideo(videoPath);
        }
    }

在这里我把获取路径封装成了一个类,贴一下这个类的代吗

public class GetPathFromUri {

    @SuppressLint("NewApi")
    public static String getPath(final Context context, final Uri uri) {

        final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;

        // DocumentProvider
        if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
            // ExternalStorageProvider
            if (isExternalStorageDocument(uri)) {
                final String docId = DocumentsContract.getDocumentId(uri);
                final String[] split = docId.split(":");
                final String type = split[0];

                if ("primary".equalsIgnoreCase(type)) {
                    return Environment.getExternalStorageDirectory() + "/" + split[1];
                }

                // TODO handle non-primary volumes
            }
            // DownloadsProvider
            else if (isDownloadsDocument(uri)) {

                final String id = DocumentsContract.getDocumentId(uri);
                final Uri contentUri = ContentUris.withAppendedId(
                        Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));

                return getDataColumn(context, contentUri, null, null);
            }
            // MediaProvider
            else if (isMediaDocument(uri)) {

我在这里判断了是否是小米手机,判断识别是否是小米设备可以参考我的另一篇博客

Android 判断手机设备是否是小米设备,是因为我目前遇到的是小米设备会有这种问

题需要处理,其他手机如果用这种方法的话可能会多此一举了,具体也是看需求了,我们看下如果其他手机用这种方法的情况下的效果图.
