android 图片选择器 L-Picture

使用方法

1. 在项目的build.gradle添加如下代码

allprojects {
    repositories {
        ...
        maven { url 'https://www.jitpack.io' }
    }
}

2. 在app的build.gradle天下如下代码

implementation 'com.github.luqihua:L-Picture:1.0'

3. 配置图片显示器(根据不同的图片加载框架配置，可能是glide,picasso,imageloader)，demo使用简单的 picasso

public class MyApplication extends Application{
    @Override
    public void onCreate() {
        super.onCreate();
        //使用picasso，glide等框架的配置都类似
        LPicture.getInstance().init(new IPictureLoader() {
            @Override
            public ImageView createImageView(Context context) {
                return new ImageView(context);
            }

            @Override
            public void displayImage(Context context, ImageView view, String path) {
                Picasso.get().load("file://"+path).into(view);
            }
        });
    }
}

• 如果项目中使用的是fresco作为图片加载框架，配置代码如下

LPicture.getInstance().init(new IPictureLoader() {
            @Override
            public ImageView createImageView(Context context) {
                return new SimpleDraweeView(context);
            }

            @Override
            public void displayImage(Context context, final ImageView view, String path) {
                Uri uri = null;
                if (!path.startsWith("http")) {
                    if (!path.startsWith("file://") && !path.startsWith("content://")) {
                        path = "file://" + path;
                    }
                }
                uri = Uri.parse(path);
                if (view instanceof SimpleDraweeView) {
                    ((SimpleDraweeView) view).setImageURI(path);
                } else {
                    ImageRequest request = ImageRequest.fromUri(uri);
                    ImagePipelineFactory.getInstance()
                            .getImagePipeline()
                            .fetchDecodedImage(request, null)
                            .subscribe(new BaseBitmapDataSubscriber() {
                                @Override
                                protected void onNewResultImpl(@Nullable Bitmap bitmap) {
                                    view.setImageBitmap(bitmap);
                                }

                                @Override
                                protected void onFailureImpl(DataSource> dataSource) {

                                }
                            }, UiThreadImmediateExecutorService.getInstance());
                }
            }
        });

4. 在activity中使用

public class MainActivity extends AppCompatActivity {


    private RecyclerView rvImageListV;
    private ImageAdapter mAdapter;
    private PictureChooseDialog mPhotoDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        if (Build.VERSION.SDK_INT >= 23) {
            requestPermissions(new String[]{Manifest.permission.CAMERA,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
        }
    }

    private void initView() {
        rvImageListV = findViewById(R.id.rv_image_list);
        rvImageListV.setLayoutManager(new GridLayoutManager(this, 3));
        mAdapter = new ImageAdapter(this);
        rvImageListV.setAdapter(mAdapter);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (mPhotoDialog != null) {
            mPhotoDialog.onActivityResult(requestCode, resultCode, data);
        }
    }

    public void choose(View v) {

        PhotoOptions options = new PhotoOptions.Builder()
                .setMaxCount(6)//目标数量
                .setCurrentCount(mAdapter.getItemCount())//当前已有数量
                .setCompress(true)//选中图片后是否进行压缩
                .build();
        mPhotoDialog = LPicture.getInstance().createPicDialog(this, options, new IPicCallback() {
            @Override
            public void success(List paths) {
                mAdapter.update(paths);
            }

            @Override
            public void error(String msg) {
                Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
            }
        });
        mPhotoDialog.show();
    }
}
