Download

Gradle:

repositories {
    jcenter()
}

dependencies {
    compile 'com.zhihu.android:matisse:0.4.3'
}

ProGuard

If you use Glide as your image engine, you may need the following rules:

-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}

# for DexGuard only
-keepresourcexmlelements manifest/application/meta-data@value=GlideModule

If you use Picasso as your image engine, you may need the following rules:

-dontwarn com.squareup.okhttp.**

How do I use Matisse?

Permission

The library requires two permissions:

• android.permission.READ_EXTERNAL_STORAGE
• android.permission.WRITE_EXTERNAL_STORAGE

So if you are targeting Android 6.0+, you need to handle runtime permission request before next step.

Simple usage snippet

Start MatisseActivity from current Activity or Fragment :

Matisse.from(MainActivity.this)
        .choose(MimeType.of(MimeType.JPEG, MimeType.PNG, MimeType.GIF))
        .countable(true)
        .maxSelectable(9)
        .addFilter(new GifSizeFilter(320, 320, 5 * Filter.K * Filter.K))
        .gridExpectedSize(getResources().getDimensionPixelSize(R.dimen.grid_expected_size))
        .restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED)
        .thumbnailScale(0.85f)
        .imageEngine(new GlideEngine())
        .forResult(REQUEST_CODE_CHOOSE);

Themes

There are two built-in themes you can use to start MatisseActivity :

• R.style.Matisse_Zhihu (light mode)
• R.style.Matisse_Dracula (dark mode)

And Also you can define your own theme as you wish.

Receive Result

In onActivityResult() callback of the starting Activity or Fragment :

List<Uri> mSelected;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_CHOOSE && resultCode == RESULT_OK) {
        mSelected = Matisse.obtainResult(data);
        Log.d("Matisse", "mSelected: " + mSelected);
    }
}
