## 怎么使用

>更多使用，请查看demo

**1.首先在跳转的Activity中**
> TransitionsHeleper.startActivity(this, ImageDetailActivity.class, view, load);

**2. 在目标Activity/Fragment中的onCreate中**
```
    TransitionsHeleper.build(this)
                .setShowMethod(new ColorShowMethod(R.color.bg_teal_light, R.color.bg_purple) {
                    @Override
                    public void loadPlaceholder(InfoBean bean, ImageView placeholder) {
                        Glide.with(ImageDetailActivity.this)
                                .load(bean.getLoad())
                                .centerCrop()
                                .into(placeholder);
                    }

                    @Override
                    public void loadTargetView(InfoBean bean, View targetView) {
                        Glide.with(ImageDetailActivity.this)
                                .load(bean.getLoad())
                                .centerCrop()
                                .into((ImageView) targetView);
                        tv.setText("immortalz");
                    }
                })
                .setExposeColor(getResources().getColor(R.color.bg_purple))
                .intoTargetView(ivDetail)
                .show();
```

**3. 为了避免内存泄漏，及时回收相关变量，在onPause中**
```
    @Override
    protected void onPause() {
        super.onPause();
        TransitionsHeleper.onPause(this);
    }
```
