為pre-Lollipop設備實現activity轉換：PreLollipopTransition

一個簡單的工具，能夠幫助針對為pre-Lollipop設備實現activity轉換效果。

Start Activity in first activity.

findViewById(R.id.imageView).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        final Intent intent = new Intent(MainActivity.this, SubActivity.class);
        ActivityTransitionLauncher.with(MainActivity.this).from(v).launch(intent);
    }
});

Receive intent in second activity.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sub);
        ActivityTransition.with(getIntent()).to(findViewById(R.id.sub_imageView)).start(savedInstanceState);
    }
