图片裁剪(基于RxPaparazzo)

前言：基于RxPaparazzo的图片裁剪，图片旋转、比例放大|缩小。

效果：

开发环境：AndroidStudio2.2.1+gradle-2.14.1

引入依赖：

     compile 'com.android.support:appcompat-v7:24.+'    //RxPaparazzo 拍照&相册//    compile "com.github.miguelbcr:RxPaparazzo:0.4.2-2.x"    compile ("com.github.miguelbcr:RxPaparazzo:0.5.2-2.x") {        exclude module: 'okhttp'        exclude module: 'okio'    }    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'    compile 'com.android.support:cardview-v7:24.+'//    compile 'com.android.support:customtabs:24.+'    compile 'com.android.support:design:24.+'    compile 'com.jakewharton:butterknife:7.0.1'

涉及知识：

1.Material Design（CardView+CoordinatorLayout+AppBarLayout+NestedScrollView+

CollapsingToolbarLayout+Toolbar+FloatingActionButton）使用

2.butterknife注解式开发

3.基于RxJava+RxAndroid的RxPaparazzo使用

部分代码：

public class MainActivity extends AppCompatActivity {    @Bind(R.id.iv_appbar)    ImageView iv_appbar;    @Bind(R.id.main_toolbar)    Toolbar toolbar; /*   @BindView(R.id.btn_float)    FloatingActionButton btn_float;*/    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        initToolBar();    }    private void initToolBar() {        this.setSupportActionBar(toolbar);        toolbar.setTitle("我的");    }    @OnClick({R.id.main_toolbar, R.id.btn_float})    public void onClick(View view) {        final UCrop.Options options = new UCrop.Options();        int color = ContextCompat.getColor(view.getContext(), R.color.colorPrimary);        options.setToolbarColor(color);        options.setStatusBarColor(ContextCompat.getColor(view.getContext(), R.color.colorPrimaryDark));        options.setActiveWidgetColor(color);        switch (view.getId()) {            case R.id.main_toolbar:                Toast.makeText(MainActivity.this, "Toolbar点击", Toast.LENGTH_SHORT).show();                break;            case R.id.btn_float: {                showDialog(view, options);                break;            }        }    }    private void showDialog(View view, final UCrop.Options options) {        final Context context = view.getContext();
