解决方法

首先声明您的图像按钮如下

imageFb=(ImageButton)findViewById(R.id.imageButton);
        imageInsta=(ImageButton)findViewById(R.id.insta);

并使用OnClickListener

imageFb.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                flick(v);
            }
        });
        imageInsta.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                incline(v);
            }
        });

现在检查它应该工作!!你已经在xml中定义了你的onClick但没有使用它并将视图传递给方法,所以它崩溃了你的代码！

最终的MainActivity应该是这样的！
