Question

这是我的主要活动请帮我例如，当我触摸家庭秀活动家 IDE（Android Studio） http://flameit.ir/MainActivity.java

Answer 1

在适配器中声明新变量

Context mContext;

替换你的适配器构造函数

 MyAdapter(String Titles[], int Icons[], String Name, String Email, int Profile) {
        mNavTitles = Titles;
        mIcons = Icons;
        name = Name;
        email = Email;
        profile = Profile;

    }

以下

 MyAdapter(String Titles[], int Icons[], String Name, String Email, int Profile,Context cntx) {
        mNavTitles = Titles;
        mIcons = Icons;
        name = Name;
        email = Email;
        profile = Profile;
        mContext=cntx;
    }

初始化您的适配器

mAdapter = new MyAdapter(TITLES,ICONS,NAME,EMAIL,PROFILE,MainActivity.this);

现在你要调用新活动的地方

Intent itt=new Intent(mContext,YourNew.class);
mContext.startActivity(itt);

如果你想在你的适配器下面的recycleview适配器上调用新活动

public ViewHolder(View itemView, int ViewType) {
            super(itemView);


            if (ViewType == TYPE_ITEM) {
                textView = (TextView) itemView.findViewById(R.id.rowText);
                imageView = (ImageView) itemView.findViewById(R.id.rowIcon);
                Holderid = 1;
            } else {


                Name = (TextView) itemView.findViewById(R.id.name);
                email = (TextView) itemView.findViewById(R.id.email);
                profile = (ImageView) itemView.findViewById(R.id.circleView);
                Holderid = 0;
            }
        itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        Intent itt=new Intent(mContext,YourNew.class);
        mContext.startActivity(itt);

        }
    });

        }

代码转到main activty Adapter
