https://github.com/gzu-liyujiang/androidpickerA comprehensive library of Android picker components providing bottom-sheet style selection interfaces. It includes specialized pickers for dates, time, addresses (Province/City/District), numbers, colors, files, and images. The library features a CalendarPicker with customizable color schemes, an ImagePicker with integrated camera/gallery access and cropping via ActivityBuilder, and an OptionPicker for custom object lists. Available modules include Common, WheelView, WheelPicker, AddressPicker, FilePicker, ColorPicker, CalendarPicker, and ImagePicker.
AndroidPicker provides a variety of wheel-style picker components for Android applications. Supported picker types include:
AndroidPicker is a comprehensive Android library providing various picker components, including:
AndroidPicker provides a unified interface for selecting images from the camera or gallery, followed by an optional cropping step.
Important: Permissions Before calling the picker, you must ensure your application has been granted the following permissions by the user:
CAMERAREAD_EXTERNAL_STORAGEWRITE_EXTERNAL_STORAGEAdd the specific picker modules you need to your module-level build.gradle file. Replace <version> with the desired version number.
Available Modules:
Common: Base window forms for custom popups.WheelView: Wheel controls for custom wheel pickers.WheelPicker: Single-item, number, multi-level linked, and date/time wheel pickers.AddressPicker: Province/City/District address picker.FilePicker: File and directory picker.ColorPicker: Color picker.CalendarPicker: Calendar date picker.ImagePicker: Image picker.There are two ways to customize styles:
picker.getWheelView().setStyle(R.style.YourStyle) to apply a specific style from res/values/styles.xml to a single instance.WheelDefault style in res/values/styles.xml to affect all pickers in the app.Since all XXXPicker classes inherit from android.app.Dialog, they can be easily integrated into an androidx.fragment.app.DialogFragment by returning the picker instance in onCreateDialog.
public class OptionPickerFragment extends DialogFragment {
@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
OptionPicker picker = new OptionPicker(requireActivity());
picker.setData("土人", "里民子", "羡民", "穿青人", "不在56个民族之内", "未定民族");
picker.setOnOptionPickedListener(new OnOptionPickedListener() {
@Override
public void onOptionPicked(int position, Object item) {
Toast.makeText(requireContext(), item.toString(), Toast.LENGTH_SHORT).show();
}
});
picker.getWheelView().setStyle(R.style.WheelStyleDemo);
return picker;
}
}Use ImagePicker.getInstance() to launch the selection flow. You must pass the current Activity, a boolean for whether to enable cropping, and your PickCallback implementation.
Required Activity Overrides
To ensure the picker functions correctly, you MUST forward the following activity lifecycle methods to the ImagePicker instance:
onActivityResult(int requestCode, int resultCode, @Nullable Intent data)onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)public class ImagePickerActivity extends FragmentActivity {
private final PickCallback cropCallback = new PickCallback() {
@Override
public void onPermissionDenied(String[] permissions, String message) {
// Handle permission denial
}
@Override
public void cropConfig(ActivityBuilder builder) {
builder.setMultiTouchEnabled(true)
.setGuidelines(CropImageView.Guidelines.ON_TOUCH)
.setCropShape(CropImageView.CropShape.OVAL)
.setRequestedSize(400, 400)
.setFixAspectRatio(true)
.setAspectRatio(1, 1);
}
@Override
public void onCropImage(@Nullable Uri imageUri) {
// Handle the cropped image Uri
}
};
public void onCamera(View view) {
// Start camera selection with cropping enabled
ImagePicker.getInstance().startCamera(this, true, cropCallback);
}
public void onGallery(View view) {
// Start gallery selection with cropping enabled
ImagePicker.getInstance().startGallery(this, true, cropCallback);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
ImagePicker.getInstance().onActivityResult(this, requestCode, resultCode, data);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
ImagePicker.getInstance().onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}
}READ_EXTERNAL_STORAGE permission by the user to comply with security requirements and allow reading from external storage.To use AndroidPicker, you must add the JitPack repository to your Gradle configuration. The method depends on your Gradle version.
For Gradle versions below 7.0:
Add the repository to your project-level build.gradle file.
For Gradle versions 7.0 and above:
Add the repository to your settings.gradle file within the dependencyResolutionManagement block.
// For Gradle < 7.0 in project-level build.gradle
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}
// For Gradle >= 7.0 in settings.gradle
dependencyResolutionManagement {
repositories {
maven { url 'https://jitpack.io' }
