Example Image

Usage

app:build.gradle

dependencies {
    compile project(':graffiti')
}

graffiti: build.gradle (需要依赖fresco)

dependencies {
    compile 'com.facebook.fresco:fresco:0.12.0'
    compile 'com.facebook.fresco:animated-gif:0.12.0'// 支持 GIF 动图,需要添加
    compile 'com.facebook.fresco:imagepipeline-okhttp3:0.12.0+'
}

初始化:

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        GraffitiConfig.init(getApplicationContext());//只需要在使用前初始化就可以了
        //Fresco初始化
        ImagePipelineConfig config = OkHttpImagePipelineConfigFactory.newBuilder(getApplicationContext(), new OkHttpClient())
                .setDownsampleEnabled(true)
                .build();
        Fresco.initialize(getApplicationContext(), config);
    }
}

在代码中使用:

 mGraffitiView = new GraffitiView(getContext());
        mGraffitiView.setOnLoadFinishListener(this);
        mGraffitiView.setOnGraffitiViewOnClick(onGraffitiViewOnClickListener);
        mGraffitiView.setId(R.id.graffitiview);     //setId,当页面被移除后恢复时GraffitiView调用保存状态
        mGraffitiView.setSaveEnabled(true);

添加网络图片或本地图片:

    private void setImage(String path, String url) {
        //优先使用本地文件

        if (mGraffitiView == null) {
            mGraffitiView = new GraffitiView(getContext());
            mGraffitiView.setOnLoadFinishListener(this);
            mGraffitiView.setOnGraffitiViewOnClick(onGraffitiViewOnClickListener);
        }
        if (!TextUtils.isEmpty(path)) {
            mGraffitiView.setImageUri("file://" + path);
        } else {
            mGraffitiView.setImageUri(url);
        }
    }
