ScrollView nesting solution EditText associated with the slide

EditText slip event ScrollView solution nested, and unite with sliding between both of them. What is it associated with sliding, sliding in the end is when EditText part of the time, then they should be allowed to slide along the outside of ScrollView, so that the sliding event is complete continuity between them. Let's look at the effect.

Online could not find an example of a full implementation, he had his own line and the demo.
Annotated code, all code is as follows:

activity codes, the following is ImmersionBar of third-party libraries, used to monitor keyboard input method when disappear, so edittext loses focus, otherwise edittext cursor has been difficult to look at.

@Override
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initStatusBar(edittext1, edittext2, edittext3, edittext4, edittext5);
}
public void initStatusBar(final EditText... ets){
        ImmersionBar.with(this)
                .fitsSystemWindows(true)
                .statusBarColor(R.color.color1)
                .keyboardEnable(true)
                .setOnKeyboardListener(new OnKeyboardListener() {
                    @Override
                    public void onKeyboardChange(boolean isPopup, int keyboardHeight) {
                        if (!isPopup) {
                            for (EditText et:ets
                            ) {
                                et.clearFocus();
                            }
                        }
                    }
                })
                .init();
