8Query

Easy to build selection and selectionArgs for sql.

A SQLiteQueryBuilder.appendWhere(where) of whereClause alternative.

Usage

For example:

A = 1 AND B = 2 OR C = 3

Before:

String selection = "A = ? and B = ? OR C = ?"; String[] selectionArgs = new String[] {
 "1", "2", "3" 
}
;  getContentResolver().query(uri, projections, selection, selectionArgs, sortOrder);

After:

Squery squery = $.equal("A", 1).and().equal("B", 2).or().equal("C", 3);
  getContentResolver().query(uri, projections, squery.selection, squery.selectionArgs, sortOrder);
 // whereClause // String sql = squery.toString();
 // (A = '1') AND (B = '2') OR (C = '3')

Orderby:

squery = squery.desc("D").asc("E").limit(10);
  getContentResolver().query(uri, projections, squery.selection, squery.selectionArgs, squery.orderBy);

For another example about block:

(A = 1 and B = 2) OR (C = 3)
    1. Use of()
$.of(
  $.equal("A", 1).and().equal("B", 2) ).or().equal("C", 3);
    1. Use begin() + end()
$.begin()
.equal("A", 1).and().equal("B", 2)  .end()  .or().equal("C", 3);
    1. Structured or operator
$.or(
  $.equal("A", 1).and().equal("B", 2),
  $.equal("C", 3) );
    1. Structured and operator
$.and(
  $.equal("A", 1),
  $.equal("B", 2) ) .or() .equal("C", 3);
    1. Structured or + and operators
$.or(
  $.and(

$.equal("A", 1),

$.equal("B", 2)
  ),
  $.equal("C", 3) );

Operators

$.in()
squery = $.in("Id", Arrays.asList("1", "2", "3"));
 System.out.println(squery.toString());
 // (Id IN (1,2,3))

Installation

via jcenter

repositories {

  jcenter() 
}
  dependencies {

  compile 'com.infstory:squery:1.0.2' 
}

Or via jitpack.io

repositories {

  maven {

url "https://jitpack.io"
  
}
 
}
  dependencies {

  compile 'com.github.yongjhih:squery:-SNAPSHOT' 
}

For ActiveAndroid

List<Note> notes = new Select().from(Note.class)
  .where(squery.selection, squery.selectionArgs)
  .execute();

Test

$ ./gradlew test :squery:test  squery.MainTests > testEqual PASSED  squery.MainTests > testCascadedAndOr STANDARD_OUT
  (A = '1') AND (B = '2') OR (C = '3')
  (A = ?) AND (B = ?) OR (C = ?), [1, 2, 3]  squery.MainTests > testCascadedAndOr PASSED  squery.MainTests > testCombineCascadedStructuredAndOr STANDARD_OUT
  (((A = '1') AND (B = '2')) OR ((C = '3')))
  (((A = ?) AND (B = ?)) OR ((C = ?))), [1, 2, 3]
  (((A = '1')) AND ((B = '2'))) OR (C = '3')
  (((A = ?)) AND ((B = ?))) OR (C = ?), [1, 2, 3]
  (((((A = '1')) AND ((B = '2')))) OR ((C = '3')))
  (((((A = ?)) AND ((B = ?)))) OR ((C = ?))), [1, 2, 3]  squery.MainTests > testCombineCascadedStructuredAndOr PASSED  squery.MainTests > testIn PASSED

Resources

A simple easy-to-integrate Camera Fragment for Android.

CameraFragment preview directly the camera view, and provides a easy API to capture or manage the device.

You can setup your own layout and control the camera using CameraFragment.

Another approach to create NavigationDrawer with Material concepts.

async-expandable-list contains 2 View classes: CollectionView and AsyncExpandableListView.

AsyncExpandableListView displays a list of headers and loads a sub-list under a header when a header item is clicked. The loading of sub-items can be done asynchronously and there are callbacks to populate the data into the list when it's done loading.

This is a demo project on Flatbuffers. Flatbuffers is an android parsing library which is much faster then GSON.

This project explains how to setup flatbuffers and use them to serialize and deserialize the models.

Gradle script for downsizing graphical assets in development builds

Usually you don't care how big the deployed APK is. However, if you are using metered connection and remote ADB, it would be good idea to build possibly smallest APK file.

Uglyfier for Android is a gradle script which will shrink all image resources in your application during build. It will look ugly, but image files will be 10 times smaller. Ninepatch (9-patch) PNGs are fully supported, with transparency preserved!

Animated Time View like Timely app.
