creator的Editbox挡住问题

Editbox是creator的老问题，各个版本都有各种各样的bug，处理creator的Editbox顶的太高问题，挡住都看不到内容了，新的creator2.2.1-2.4.3都有顶太高的问题，不能选择黏贴问题。
解决方案如下：

1）js代码添加：

if (cc.sys.os == cc.sys.OS_ANDROID && cc.sys.isNative) {
    cc.EditBox.prototype._onTouchBegan = function (event) {
        let touch = event.touch
        let node = event.target
        let upLoadY = touch.getLocationY()
        let nodePos = node.convertToNodeSpaceAR(touch.getLocation())
        upLoadY -= nodePos.y + node.height / 2
        console.log('up Y', upLoadY)
        jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "upLoadEditBoxY", "(Ljava/lang/String;)V", upLoadY * cc.view.getScaleY())
    }
}

2)java更改1，代码更改，找到文件C:/CocosCreator2.2.1/resources/cocos2d-x/cocos/platform/android/java/src/org/cocos2dx/lib/Cocos2dxActivity.java文件修改349行，改为这个

window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING)

继续添加添加

public static float mEditBoxY = 0;

继续修改init函数，添加一行mEditBox = new Cocos2dxEditBox(this, mFrameLayout);隐藏自带的输入框，下面还有一行不用管。

mEditBox = new Cocos2dxEditBox(this, mFrameLayout);
Cocos2dxRenderer renderer = this.addSurfaceView();

3）java更改2，AppActivity.java添加函数

// 接收Y坐标
public static void upLoadEditBoxY(String y){
    mEditBoxY=Float.parseFloat(y);
}

4）java更改3，Cocos2dxEditBox.java文件,修改registKeyboardVisible方法

private void registKeyboardVisible() {
    getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            Rect r = new Rect();
            getWindowVisibleDisplayFrame(r);
            int heightDiff = getRootView().getHeight() -(r.bottom-r.top);
            // if more than a quarter of the screen, its probably a keyboard
            if (heightDiff > mScreenHeight/4) {
                if (!keyboardVisible) {
                    keyboardVisible = true;

                    if(heightDiff>Cocos2dxActivity.mEditBoxY){
                        GLSurfaceView gl=mActivity.getGLSurfaceView();
                        Log.i(TAG, "Cocos2dxActivity.mEditBoxY: "+Cocos2dxActivity.mEditBoxY);
                        float moveY=-(heightDiff-Cocos2dxActivity.mEditBoxY);
                        gl.setY(moveY);
                    }
                }
            } else {
                if (keyboardVisible) {
                    keyboardVisible = false;
                    Cocos2dxEditBox.this.hide();
                    GLSurfaceView gl=mActivity.getGLSurfaceView();
                    gl.setY(0);
                }
            }
        }
    });
}

5）继续修改Additems方法，注释这行layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
6）搞定！试试看吧。
