3 |

5 |
6 | Custom Image Picker is a popup image picker for quick selection of recent images. This photo chooser does not require a custom image provider. Custom Image Picker works great for choosing images in a chat app, selecting a profile image, or any quick image selection needs.

14 | This library is part of the [Custom UI](http://rayliverified.com/index.php/code/) collection of beautiful, minimalistic, and customizable Android UI components.
15 |
16 | # Gradle Dependency
17 |
18 | Add this line to your `build.gradle` project. Use the latest release version for the version code.
19 |
20 | ```java
21 | repositories {
22 | maven { url 'https://jitpack.io' }
23 | }
24 | compile 'com.github.searchy2:CustomImagePicker:latest-version'
25 | ```
26 | # Usage
27 |
28 | ### Code
29 |
30 | Custom Image Picker uses a Dialog popup to display the image gallery. Copy the following code into your project and you will have a working image picker. It's that simple!
31 |
32 | First, initialize the bottom sheet layout of our image picker gallery and create the popup dialogue.
33 |
34 | ```java
35 | final View bottomSheet = getLayoutInflater().inflate(R.layout.bottom_sheet, null);
36 | final Dialog mBottomSheetDialog = new Dialog(this, R.style.MaterialDialogSheet);
37 | mBottomSheetDialog.setContentView(bottomSheet);
38 | mBottomSheetDialog.setCancelable(true);
39 | mBottomSheetDialog.getWindow().setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
40 | mBottomSheetDialog.getWindow().setGravity(Gravity.BOTTOM);
41 | ```
42 |
43 | Next, create the image gallery adapter and show it to the user.
44 |
45 | ```java
46 | CustomImagePicker imagePicker = new CustomImagePicker();
47 | imagePicker.setHeight(100);
48 | imagePicker.setWidth(100);
49 | ImageAdapter adapter = imagePicker.getAdapter(MainActivity.this);
50 |
51 | TwoWayGridView gridview = bottomSheet.findViewById(R.id.gridview);
52 | gridview.getLayoutParams().height = Units.dpToPx(mContext, 200);
53 | gridview.setNumRows(2);
54 | gridview.setAdapter(adapter);
55 | gridview.setOnItemClickListener(new TwoWayAdapterView.OnItemClickListener() {
56 | public void onItemClick(TwoWayAdapterView parent, View v, int position, long id) {
57 | imageUri = ContentUris.withAppendedId(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id);
58 | //Do what you want with the returned imageUri here.
59 | mBottomSheetDialog.dismiss();
60 | }
61 | });
62 |
63 | mBottomSheetDialog.show();
64 | ```
65 |
66 | That's it! Now you have a fancy new image picker!
67 |
68 | # Customization
69 |
70 | ### Layouts
71 |
72 | Custom Image Picker is highly customizable. The default `bottom_sheet_default.xml` layout contains only an image gallery but you can design your own image picker layout or use an existing layout. Please view the sample app for an example image layout with action sheet buttons that capture a photo and open the device image gallery.
73 |
74 | ### Builder Attributes
75 |
76 | `getAdapter(Context context)` - default method to get adapter
77 |
78 | `getAdapter(Context context, String columns, String sort)` - filter available images and sort in `Descending` or `Ascending` order.
79 |
80 | `setDrawable(int drawable)` - set drawable resource Id to replace default placeholder image.
81 |
82 | `setHeight(int height)` - set image height (dp).
83 |
84 | `setWidth(int width)` - set image width (dp).
85 |
86 | `setPadding(int padding)` - set image padding (dp).
87 |
88 | `setSize(int size)` - set 1, 2, 3, 4 for image thumbnail quality. 1 is the best quality and 4 is the lowest quality. Default 1.
