三、使用

1）基本使用

myDialog = new AlertDialog(this).builder();
myDialog.setGone().setTitle("提示").setMsg("仿iOS的弹窗").setNegativeButton("取消",null).setPositiveButton("确定", new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        
                    }
                }).show();

2）修改按钮文字颜色

 myDialog.setGone().setMsg("仿iOS的弹窗，看看实际效果如何呢，仿iOS的弹窗，仿iOS的弹窗").setNegativeButton("取消",R.color.colorAccent,null).setPositiveButton("确定",R.color.colorAccent,null).show();

3）弹窗一个按钮

  myDialog.setGone().setMsg("仿iOS的弹窗").setPositiveButton("确定",null).show();
    或
  myDialog.setGone().setMsg("仿iOS的弹窗").setNegativeButton("确定",null).show();

4）dialog完整代码
