Android image picker (select multiple images)

I haven't written an article for a long time. Recently, I have been busy with some things about the company's desktop maintenance. A few days ago, I received a task to write a copy of WeChat to select multiple pictures. Today, I will summarize it. I found a very useful image selection library. Let's talk about the usage of this library:

1. Grab and import the Jar package through Gradle (Glide and RecyclerView, there is a connection at the end of the article)

 

compile 'com.yancy.imageselector:imageselector:1.1.0'

2. Add the following permissions to AndroidManifest.xml

<!-- Permission to read data from sdcard-->  
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />  
<!-- Permission to write data to sdcard-->  
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  

3. Create an image loader (Glide is recommended ) 

public class GlideLoader implements com.yancy.imageselector.ImageLoader {  
 @Override  
 public void displayImage(Context context, String path, ImageView imageView) {  
  Glide.with(context)  
    .load(path)  
    .placeholder(com.yancy.imageselector.R.mipmap.imageselector_photo)  
    .centerCrop()  
    .into(imageView);  
 }  
  
}  

4. Configure ImageSelector

ImageConfig imageConfig  
  = new ImageConfig.Builder(MainActivity.this , new GlideLoader())  
  // If it is above 4.4, modify the status bar color (default black)  
  .steepToolBarColor(getResources().getColor(R.color.blue))  
  // background color of the title (default black)  
  .titleBgColor(getResources().getColor(R.color.blue))  
  // The color of the submit button font (default white)  
  .titleSubmitTextColor(getResources().getColor(R.color.white))  
  // title color (default white)  
  .titleTextColor(getResources().getColor(R.color.white))  
  // Enable multiple selection (multiple selection by default) (singleSelect for single selection)  
  .mutiSelect()  
  // Maximum number of multiple selections (default 9)  
  .mutiSelectMaxSize(9)  
  // selected image path  
  .pathList(path)  
  // The image path stored after taking a photo (default /temp/picture)  
  .filePath("/ImageSelector/Pictures")  
  // Enable the camera function (off by default)  
  .showCamera()  
  .build();  
  
  
ImageSelector.open(imageConfig); // Open the image selector  

5. Get the selected photo path array in onActivityResult:

@Override  
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
  super.onActivityResult(requestCode, resultCode, data);  
  if (requestCode == ImageSelector.IMAGE_REQUEST_CODE && resultCode == RESULT_OK && data != ) {  
  
  
   // Get Image Path List  
   List<String> pathList = data.getStringArrayListExtra(ImageSelectorActivity.EXTRA_RESULT);  
  
  
   for (String path : pathList) {  
    Log.e("The path of the selected picture is -----", path);  
   }  
  
  
  }  
 }
