Easy File/Folder Picker Dialog Fragment

An easy file / folder picker dialog fragment which is easily to implement. Nothing special is required, you just need to add few lines of code!!

Installing

Use Gradle:

compile 'com.kingfisherphuoc:easy-file-folder-picker-dialog:1.4'

How to use?

Look at this code below? Is this easy? Nothing special is require.
You just need using FilePickerDialogFragment.Builder() to create new instance of FilePickerDialogFragment and show it whenever you want. We handle runtime permission for you when showing the dialog.
The DialogConfig is optional. You can declare it or not, it's up to you.

 DialogConfig dialogConfig = new DialogConfig.Builder()
                .enableMultipleSelect(true) // default is false
                .enableFolderSelect(true) // default is false
                .initialDirectory(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "Android") // default is sdcard
                .supportFiles(new SupportFile(".3gpp", R.drawable.ic_audio), new SupportFile(".mp3", 0), new SupportFile(".pdf", R.drawable.ic_pdf)) // default is showing all file types.
                .build();

new FilePickerDialogFragment.Builder()
                .configs(dialogConfig) 
                .onFilesSelected(new FilePickerDialogFragment.OnFilesSelectedListener() {
                    @Override
                    public void onFileSelected(List<File> list) {
                        Log.e(TAG, "total Selected file: " + list.size());
                        for (File file : list) {
                            Log.e(TAG, "Selected file: " + file.getAbsolutePath());
                        }
                    }
                })
                .onFolderLoadListener(new FilePickerDialogFragment.OnFolderLoadListener() {
                    @Override
                    public void onLoadFailed(String path) {
                        //Could not access folder because of user permissions, sdcard is not readable...
                    }
                })
                .build()
                .show(getSupportFragmentManager(), null);

You can even customize everything in the dialog. Look at the exapmle MyExampleCustomDialog as below. Some properties are optional (like current folder path, toolbar, done button...).

public class MyExampleCustomDialog extends BaseFilePickerDialogFragment {
    @NonNull
    @Override
    protected int getLayoutId() {
        return R.layout.dialog_custom;
    }

    @NonNull
    @Override
    protected int getRecyclerViewId() {
        return R.id.recyclerview;
    }

    @Nullable
    @Override
    protected int getTextViewCurrentFolderId() {
        return 0;
    }

    @Override
    protected int getToolbarId() {
        return R.id.myToolBar;
    }

    @Nullable
    @Override
    protected int getDoneButtonId() {
        return 0;
    }

    @NonNull
    @Override
    protected int getLayoutRowId() {
        return R.layout.item_row;
    }

    @NonNull
    @Override
    protected int getImageViewIconId() {
        return R.id.ivImage;
    }

    @NonNull
    @Override
    protected int getTextViewNameId() {
        return R.id.tvName;
    }

    @NonNull
    @Override
    protected int getCheckBoxId() {
        return R.id.checkbox;
    }


    @Override
    protected RecyclerView.LayoutManager getInitialLayoutManager() {
        return new GridLayoutManager(getContext(), 3);
    }


    @Override
    protected void initView(View view) {
        super.initView(view);
        toolbar.inflateMenu(R.menu.menu_custom_dialog);
        toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.actionDone:
                        doneSelecting();//supported function to passed result to listener
                        break;
                    case R.id.actionList:
                        changeLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false));
                        break;
                    case R.id.actionGrid:
                        changeLayoutManager(new GridLayoutManager(getContext(), 3));
                        break;
                }

                return false;
            }
        });
    }

    public static MyExampleCustomDialog newInstance(FilePickerDialogFragment.OnFilesSelectedListener onFilesSelectedListener, DialogConfig dialogConfig) {
        MyExampleCustomDialog myExampleCustomDialog = new MyExampleCustomDialog();
        myExampleCustomDialog.onFilesSelectedListener = onFilesSelectedListener;
        myExampleCustomDialog.dialogConfig = dialogConfig;
        return myExampleCustomDialog;
    }
}

What's in the next version?

If I have free time, I will make this dialog more customizable:

1. Customizable dialog theme
2. Customizable dialog UI (recycler view's row, button, toolbar...)

Feel free to create an issue if you had any problem.
