-------------------

###Run Demo

>./gradlew installDebug

###Quick Start
* Step 0
Add module `multi-image-selector` as your dependence. in your `build.gradle` :
```java
repositories {
    maven { url "https://jitpack.io" }
}

dependencies {
    compile 'com.github.lovetuzitong:MultiImageSelector:1.2'
}
```

* Step 1 
Set your `AndroidManifest.xml` as below:
```xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<application

    ...

    <!--Image Selector Entry-->
    <activity
        android:configChanges="orientation|screenSize"
        android:name="me.nereo.multi_image_selector.MultiImageSelectorActivity" />
</application>
```

* Step 2
Call image selector simplest in your code, eg. ( From `version-1.1` )

``` java
// Multi image selector form an Activity
MultiImageSelector.create(Context)
        .start(Activity, REQUEST_IMAGE);
```

Detail Api.
``` java
MultiImageSelector.create(Context)
        .showCamera(boolean) // show camera or not. true by default
        .count(int) // max select image size, 9 by default. used width #.multi()
        .single() // single mode
        .multi() // multi mode, default mode;
        .origin(ArrayList<String>) // original select data set, used width #.multi()
        .start(Activity/Fragment, REQUEST_IMAGE);
```

Also support traditional `Intent` :
``` java
Intent intent = new Intent(mContext, MultiImageSelectorActivity.class);
// whether show camera
intent.putExtra(MultiImageSelectorActivity.EXTRA_SHOW_CAMERA, true);
// max select image amount
intent.putExtra(MultiImageSelectorActivity.EXTRA_SELECT_COUNT, 9);
// select mode (MultiImageSelectorActivity.MODE_SINGLE OR MultiImageSelectorActivity.MODE_MULTI)
intent.putExtra(MultiImageSelectorActivity.EXTRA_SELECT_MODE, MultiImageSelectorActivity.MODE_MULTI);
// default select images (support array list)
intent.putStringArrayListExtra(MultiImageSelectorActivity.EXTRA_DEFAULT_SELECTED_LIST, defaultDataArray);
startActivityForResult(intent, REQUEST_IMAGE);
```

* Step 3
Receive result in your `onActivityResult` Method. eg.
```java
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == REQUEST_IMAGE){
        if(resultCode == RESULT_OK){
	        // Get the result list of select image paths
            List<String> path = data.getStringArrayListExtra(MultiImageSelectorActivity.EXTRA_RESULT);
            // do your logic ....
        }
    }
}
```

* Step 4
No more steps, just enjoy. :)

###Custom Activity Style
* Custome your own Activity
```java
class CustomerActivity extends Activity implements MultiImageSelectorFragment.Callback{
	@Override
    protected void onCreate(Bundle savedInstanceState) {
		// customer logic here...
		Bundle bundle = new Bundle();
        bundle.putInt(MultiImageSelectorFragment.EXTRA_SELECT_COUNT, mDefaultCount);
        bundle.putInt(MultiImageSelectorFragment.EXTRA_SELECT_MODE, mode);
        bundle.putBoolean(MultiImageSelectorFragment.EXTRA_SHOW_CAMERA, isShow);
        // Add fragment to your Activity
        getSupportFragmentManager().beginTransaction()
                .add(R.id.image_grid, Fragment.instantiate(this, MultiImageSelectorFragment.class.getName(), bundle))
                .commit();
	}
	@Override
    public void onSingleImageSelected(String path) {
        // When select mode set to MODE_SINGLE, this method will received result from fragment
    }

    @Override
    public void onImageSelected(String path) {
        // You can specify your ActionBar behavior here 
    }

    @Override
    public void onImageUnselected(String path) {
        // You can specify your ActionBar behavior here 
    }

    @Override
    public void onCameraShot(File imageFile) {
        // When user take phone by camera, this method will be called.
    }
}
```
