このコードでギャラリーを開くことができますが、
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Video"), PICK_VIDEO_REQUEST );
Samsung Galaxy S5でうまく機能します。ただし、一部の携帯電話では、画像が画像とともに表示されます。
ギャラリーを開いてonlyビデオを表示するには、コードにどのような変更を加える必要がありますか?
結果が返されたときに、選択したビデオの実際のパスを取得するにはどうすればよいですか?
ギャラリーから選択した後にビデオパスを取得する完全なコードを次に示します。
Intent intent = new Intent();
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Video"),REQUEST_TAKE_GALLERY_VIDEO);
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_TAKE_GALLERY_VIDEO) {
Uri selectedImageUri = data.getData();
// OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
// MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
if (selectedImagePath != null) {
Intent intent = new Intent(HomeActivity.this,
VideoplayAvtivity.class);
intent.putExtra("path", selectedImagePath);
startActivity(intent);
}
}
}
}
// UPDATED!
public String getPath(Uri uri) {
String[] projection = { MediaStore.Video.Media.DATA };
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
if (cursor != null) {
// HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
// THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else
return null;
}
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent , SELECT_VIDEO);
このメソッドgetPathから実際のパスを取得します

これを使って

Intent.setType("video/*");
startActivityForResult(Intent.createChooser(intent,"SelectVideo"),REQUEST_TAKE_GALLERY_VIDEO);
@Override

super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
Uri selectedVideoUri = data.getData();
// OI FILE Manager
String filemanagerstring = selectedVideoUri.toString();
vidPath = filemanagerstring;
// MEDIA GALLERY
String selectedVideoPath = getPath(selectedVideoUri);
if (selectedVideoPath != null) {
vidPath = selectedVideoPath;
}
}
}
}
//this function returns null when using IO file manager
public String getPath(Uri uri) {
String[] projection = { MediaStore.Video.Media.DATA };
getContentResolver();
Cursor cursor = getApplicationContext().getContentResolver().query(uri, projection, null, null, null);
if (cursor != null) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else
return null;
}
getpath()関数が「null」を返している場合は、その権限が設定されていないため、権限がありません。マニフェストにこれを貼り付ける必要があります:
<uses-permission Android:name="Android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission Android:name="Android.permission.READ_EXTERNAL_STORAGE"/>
これを<application>
タグの前に貼り付け、アプリをロードしたら、設定->アプリケーション-> YourApp->権限に移動し、すべての権限をtrueに設定します。これを行うと、このコードは完全に機能するはずです。
以下のコードは私のために働く:
Intent videoPickIntent = new Intent(Intent.ACTION_PICK);
videoPickIntent.setType("video/*");
TheActivity.startActivityForResult(Intent.createChooser(videoPickIntent, "Please pick a video"), PickIntroductionVideo);
およびonActivityResultで:
if (requestCode != PickIntroductionVideo)
return;
if (resultCode != Activity.RESULT_OK)
return true;
String pickedVideoUrl = FarayanUtility.getRealPathFromUri(getContext(), data.getData());
方法 FarayanUtility.getRealPathFromUri
は:
public static String getRealPathFromUri(Context context, Uri contentUri) {
Cursor cursor = null;
try {
String[] proj = {MediaStore.Images.Media.DATA};
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} finally {
if (cursor != null) {
cursor.close();
}
}
}
