Usage

Steps

Add gradle dependecy

dependencies {
  compile 'com.github.pawanchauhan05:utility:0.0.3'
}

How to use ?

Shared Preference

Save and get boolean value from shared perference

• Save boolean type value

Utils.savePreferenceData(getContext(), "BOOLEAN_KEY", true);

• Get boolean type value

Utils.readPreferenceData(getContext(), "BOOLEAN_KEY", false);

Save and get int value from shared perference

• Save int type value

Utils.savePreferenceData(getContext(), "INT_KEY", 5);

• Get int type value

Utils.readPreferenceData(getContext(), "INT_KEY", 0);

Save and get String value from shared perference

• Save String type value

Utils.savePreferenceData(getContext(), "STRING_KEY", "STRING_VALUE");

• Get String type value

Utils.readPreferenceData(getContext(), "STRING_KEY", "");

Save and get custom object value from shared perference

• Save custom object value

Utils.savePreferenceData(getContext(), "CUSTOM_KEY", customObject);

• Get custom object value

Utils.readPreferenceData(getContext(), "CUSTOM_KEY", customObject, CustomObject.class);

Clear particular key data

Utils.removePreferenceData(getActivity(), "REMOVE_KEY");

clear all shared preference

Utils.clearPreferences(getActivity());

"in Utils.readPreferenceData() method third perameter is default value"

Runtime Permission for marshmallow and above SDK

RunTimePermission permission = new RunTimePermission(this, new RuntimePermissionInterface() {
            @Override
            public void doTaskAfterPermission() {
                Log.e("Task","Add you task which want to complete after getting permission");
            }
        });
permission.runtimePermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        permission.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

"To prevent application to crash you also have to add permission in application manifest file"

Download audio, video, image file

• Download Audio file

Utils.downloadMusicFile("music_url", "music_file_name", getActivity());

• Download Video File

Utils.downloadVideoFile("video_url", "video_file_name", getActivity());

• Download Image File

Utils.downloadImageFile("image_url", "image_file_name", getActivity());

Show or Hide custom or default progress dialog

• Show Custom Progress Dialog

ProgressDialog progressDialog = new ProgressDialog(getActivity());
Utils.showProgressBar(progressDialog);

• Show Default Progress Dialog

ProgressDialog progressDialog = new ProgressDialog(getActivity());
Utils.showProgressBar("progress_dialog_title", "progress_dialog_message", progressDialog);

• Hide Progress Dialog

Utils.hideProgressBar(progressDialog);

"use same progress dialog instance to hideProgressBar() that used for showProgressBar()"

Check app foreground state

Utils.hasAppInForeground(getActivity());

hasAppInForeground() method returns boolean value.

"true = app in foreground AND false = app in background"

Check internet connectivity

Utils.hasInternetAccess();

hasInternetAccess() method returns boolean value.

"true = having internet access AND false = do not have internet access"

Read and write custom object from file

• Write custom object to file

FileDBUtils<CustomObject> fileDBUtils = new FileDBUtils<>(getActivity(), "file_name", CustomObject.class, "/db/custom");
fileDBUtils.saveObject(customObjectInstance);

• Read custom object from file

FileDBUtils<CustomObject> fileDBUtils = new FileDBUtils<>(getActivity(), "file_name", CustomObject.class, "/db/custom");
fileDBUtils.readObject();

Create directory (from path) and delete directory with files

• Create directory form path

Utils.createDirectory(getActivity(), "top/main/sub");

• Delete directory including files

Utils.deleteDirectory(getActivity(), "top/main/sub");

Show short or long length toast

• Show Short Toast

Utils.generateShortToast(getActivity(), "toast_message");

• Show Long Toast

Utils.generateLongToast(getActivity(), "toast_message");

Show short or long length snack bar

• Show Short length Snack bar

Utils.showShortSnackBar(getActivity(), "Snack bar message");

• Show Long length Snack bar

Utils.showLongSnackBar(getActivity(), "Snack bar message");

Alert Dialog

• Show Single Button Alert Dialog

Utils.showSingleButtonAlertDialog(this, "button_text", "dialog_title", "dialog_message", new AlertDialogSingleInterface() {
    @Override
    public void doTaskOnClick() {
	    // TODO add code which want to execute on button click
    }
});

• Show Multi Button Alert Dialog

Utils.showMultiButtonAlertDialog(this, "positive_button_name", "negative_button_name", "dialog_title", "dialog_message", new AlertDialogInterface() {
            @Override
            public void positiveButtonPressed() {
                // TODO add code which want to execute on click positive button
            }

            @Override
            public void negativeButtonPressed() {
                // TODO add code which want to execute on click negative button
            }
        });

• Show Date picker dialog

Utils.showDatePicker(getSupportFragmentManager(), new DateInterface() {
    @Override
    public void setDate(Date date) {
    	// TODO get date after select from date picker dialog   
    }
});

• Show Time picker dialog

Utils.showTimePicker(getSupportFragmentManager(), new TimeInterface() {
    @Override
    public void setTime(int hour, int minute, String am_pm) {
	    // TODO get time after select from time picker dialog     
    }
});

Hide keyboard panel

Utils.hideKeyboard(getActivity());

Choose image from camera or gallery

public class TestFragment extends Fragment implements RuntimePermissionInitializerInterface {
    private RunTimePermission permission;

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if(getRuntimePermission() != null)
            getRuntimePermission().onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        AlertDialog.imageHelperInterface.onActivityResult(requestCode, resultCode, data);
    }

    @Override
    public void setRuntimePermission(RunTimePermission runTimePermission) {
        this.permission = runTimePermission;
    }

    @Override
    public RunTimePermission getRuntimePermission() {
        return permission;
    }

    @Override
    public void setBitmap(Bitmap bitmap) {
	    // TODO get select image file in bitmap format
    }
}

"implement RuntimePermissionInitializerInterface, override onRequestPermissionsResult(), onActivityResult() method is compulsory."

Endless Scroll for List View

listViewInstance.setOnScrollListener(new ListViewEndlessScrollListener() {
            @Override
            public boolean onLoadMore(int page, int totalItemsCount) {
                /*
                TODO
                1. show progress dialog
                2. Load data from api
                3. hide progress dialog
                */
                return false; // ONLY if more data is actually being loaded; false otherwise.
            }
        });

Endless Scroll for Recycler View

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getContext());
recyclerViewInstance.setLayoutManager(linearLayoutManager);
recyclerViewInstance.addOnScrollListener(new RecyclerViewEndlessScrollListener(linearLayoutManager) {
            @Override
            public void onLoadMore(int page, int totalItemsCount, RecyclerView view) {
            /*
            TODO
            1. Show progress Dialog
            2. load data from api
            3. Hide progress Dialog
            */
            }
        });

    android:id="@+id/circularImageView"
    android:src="@drawable/drawable_name"
    android:layout_width="wrap_content"

Contribution

I welcome and encourage all pull requests. It usually will take me within 24-48 hours to respond to any issue or request. Here are some basic rules to follow to ensure timely addition of your request:

1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (Reformat code) on Mac (not sure for Windows) with Android Studio defaults.
2. If its a feature, bugfix, or anything please only change code to what you specify.
3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge :)
4. Pull requests must be made against developer branch. Any other branch (unless specified by the maintainers) will get rejected.
5. Check for existing issues first, before filing an issue.
6. Have fun!
