android-file-chooser

Overview

android-file-library is a lightweight file/folder chooser.

Snapshots

Demo Application

A demo-app can be installed from Play Store.

Changes

Since 1.1.6, AS 3.0+ + Gradle 4.1+ + Android SDK & Building Tools 26.0+ are prerequisites.

Two withXXX calls added for AlertDialog icon and layout resource. See Also: withIcon(), withLayoutView()

NOTE:

minSDK will be moved up to 14+ at next release, since we like Android Supports Library 26.+.

Usage

Configuration

build.gradle

android-file-chooser was released at jcenter, declare deps with:

implementation 'com.obsez.android.lib.filechooser:filechooser:1.1.10'

taste the fresh

there is a way to taste the master branch with jitpack.io:

1. add the jitpack repository url to your root build.gradle:

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

2. import android-file-chooser

implementation 'com.github.hedzr:android-file-chooser:master-SNAPSHOT'
// implementation 'com.github.hedzr:android-file-chooser:v1.1.10'

Codes

FileChooser android library give a simple file/folder chooser in single call:

Choose a Folder

    new ChooserDialog().with(this)
            .withFilter(true, false)
            .withStartFile(startingDir)
            .withChosenListener(new ChooserDialog.Result() {
                @Override
                public void onChoosePath(String path, File pathFile) {
                    Toast.makeText(MainActivity.this, "FOLDER: " + path, Toast.LENGTH_SHORT).show();
                }
            })
            .build()
            .show();

Choose a File

    new ChooserDialog().with(this)
            .withStartFile(path)
            .withChosenListener(new ChooserDialog.Result() {
                @Override
                public void onChoosePath(String path, File pathFile) {
                    Toast.makeText(MainActivity.this, "FILE: " + path, Toast.LENGTH_SHORT).show();
                }
            })
            .build()
            .show();

Wild-match

    new ChooserDialog().with(this)
            .withFilter(false, false, "jpg", "jpeg", "png")
            .withStartFile(path)
            .withResources(R.string.title_choose_file, R.string.title_choose, R.string.dialog_cancel)
            .withChosenListener(new ChooserDialog.Result() {
                @Override
                public void onChoosePath(String path, File pathFile) {
                    Toast.makeText(MainActivity.this, "FILE: " + path, Toast.LENGTH_SHORT).show();
                }
            })
            .build()
            .show();

Regex filter

    new ChooserDialog().with(this)
            .withFilterRegex(false, false, ".*\\.(jpe?g|png)")
            .withStartFile(path)
            .withResources(R.string.title_choose_file, R.string.title_choose, R.string.dialog_cancel)
            .withChosenListener(new ChooserDialog.Result() {
                @Override
                public void onChoosePath(String path, File pathFile) {
                    Toast.makeText(NewMainActivity.this, "FILE: " + path, Toast.LENGTH_SHORT).show();
                }
            })
            .build()
            .show();

Date Format String

Since 1.1.3, new builder options withDateFormat(String) added.

    new ChooserDialog().with(this)
            .withFilter(true, false)
            .withStartFile(startingDir)
            .withDateFormat("HH:mm")    // see also SimpleDateFormat format specifiers
            .withChosenListener(new ChooserDialog.Result() {
                @Override
                public void onChoosePath(String path, File pathFile) {
                    Toast.makeText(MainActivity.this, "FOLDER: " + path, Toast.LENGTH_SHORT).show();
                }
            })
            .build()
            .show();

Modify Icon or View Layout of AlertDialog:

Since 1.1.6, 2 new options are available:

    new ChooserDialog().with(this)
            .withFilter(true, false)
            .withStartFile(startingDir)
            .withIcon(R.drawable.ic_file_chooser)
            .withLayoutView(R.layout.alert_file_chooser)
            .withChosenListener(new ChooserDialog.Result() {
                @Override
                public void onChoosePath(String path, File pathFile) {
                    Toast.makeText(MainActivity.this, "FOLDER: " + path, Toast.LENGTH_SHORT).show();
                }
            })
            .build()
            .show();

Customizable NegativeButton

1.1.7 or Higher, try withNegativeButton() and withNegativeButtonListener().

New calling chain

1.1.7+, new constructor ChooserDialog(context) can simplify the chain invoking, such as:

    new ChooserDialog(this)
            .withFilter(true, false)
            .withStartFile(startingDir)
            ...

And, old style is still available. No need to modify your existing codes.

withRowLayoutView(resId)

1.1.8+. Now you can customize each row.

withFileIcons

1.1.9+. withFileIcons(resolveMime, fileIcon, folderIcon) and withFileIconsRes(resolveMime, fileIconResId, folderIconResId) allow user-defined file/folder icon.

resolveMime: true means that DirAdapter will try get icon from the associated app with the file's mime type.

    new ChooserDialog(ctx)
            .withStartFile(_path)
            .withResources(R.string.title_choose_any_file, R.string.title_choose, R.string.dialog_cancel)
            .withFileIconsRes(false, R.mipmap.ic_my_file, R.mipmap.ic_my_folder)
            .withChosenListener(new ChooserDialog.Result() {
                @Override
                public void onChoosePath(String path, File pathFile) {
                    Toast.makeText(ctx, "FILE: " + path, Toast.LENGTH_SHORT).show();
                }
            })
            .build()
            .show();

withAdapterSetter(setter)

1.1.9+. a AdapterSetter can be use to customize the DirAdapter.

            .withAdapterSetter(new ChooserDialog.AdapterSetter() {
                @Override
                public void apply(DirAdapter adapter) {
                    adapter.setDefaultFileIcon(fileIcon);
                    adapter.setDefaultFolderIcon(folderIcon);
                    adapter.setResolveFileType(tryResolveFileTypeAndIcon);
                }
            })

withNavigateUpTo(CanNavigateUp)

1.1.10+. withNavigateUpTo

                .withNavigateUpTo(new ChooserDialog.CanNavigateUp() {
                    @Override
                    public boolean canUpTo(File dir) {
                        return true;
                    }
                })

withNavigateTo(CanNavigateTo)

1.1.10+. withNavigateTo

                .withNavigateTo(new ChooserDialog.CanNavigateTo() {
                    @Override
                    public boolean canNavigate(File dir) {
                        return true;
                    }
                })

Under Kotlin

class MyFragment : Fragment() {

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
        val root = inflater.inflate(R.layout.fragment_book, container, false)
        root.upload_button.setOnClickListener { _: View ->
            ChooserDialog().with(activity)
                    .withStartFile(Environment.getExternalStorageDirectory().absolutePath)
                    // .withStartFile(Environment.getExternalStorageState()+"/")
                    .withFilterRegex(false, false, ".*\\.(jpe?g|png)")
                    .withChosenListener { path, pathFile -> activity!!.toast("FILE: $path / $pathFile") }
                    .build()
                    .show()
        }

        return root
    }
}

And:

        ChooserDialog(context)
                .withFilterRegex(false, true, ".*\\.(jpe?g|png)")
                .withStartFile(startPath)
                .withResources(R.string.title_choose_file, R.string.title_choose, R.string.dialog_cancel)
                .withChosenListener { path, pathFile ->
                    Toast.makeText(context, "FILE: $path; PATHFILE: $pathFile", Toast.LENGTH_SHORT).show()

                    //_path = path
                    //_tv.setText(_path)
                    ////_iv.setImageURI(Uri.fromFile(pathFile));
                    //_iv.setImageBitmap(ImageUtil.decodeFile(pathFile))
                }
                .withNavigateUpTo { true }
                .withNavigateTo { true }
                .build()
                .show()

Build me

1. legacy

cat >keystore.properties<<EOF
keyAlias=youKeyAlias
keyPassword=password
storeFile=/Users/me/android-file-chooser.keystore
storePassword=password
EOF
git clone [email protected]:hedzr/android-file-chooser.git somewhere
cd somewhere
./gradlew assembleDebug

you'd better generate a new file android-file-chooser.keystore at homedir or else. such as: keytool -genkey -alias android.keystore -keyalg RSA -validity 20000 -keystore android.keystore, see also Sign an app. Or, erase the KS_PATH lines and signature section in app/build.gradle.

2. current

just fork me and build me currently.
