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

- // 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)) {
- final String docId = DocumentsContract.getDocumentId(uri);
- final String[] split = docId.split(":");

-
- Uri contentUri = null;
- if ("image".equals(type)) {
- contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

- } else if ("audio".equals(type)) {
- contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
- }
-
- final String selection = "_id=?";
- final String[] selectionArgs = new String[]{split[1]};
-
- return getDataColumn(context, contentUri, selection, selectionArgs);
- }
- }
- // MediaStore (and general)
- else if ("content".equalsIgnoreCase(uri.getScheme())) {
- return getDataColumn(context, uri, null, null);
- }
- // File
- else if ("file".equalsIgnoreCase(uri.getScheme())) {
- return uri.getPath();
- }
-
- return null;
- }

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.
