将 ArrayList 值传递给 Intent.putExtra for Intent.ACTION_SEND [英] Passing ArrayList value to a Intent.putExtra for Intent.ACTION_SEND

问题描述

如何将 arraylist 值(samplename, samplequote )传递给 intent.putExtra.. 以共享文本..

在 MainActivity.java

 list = new ArrayList<>();

        //loading list view item with this function
        loadRecyclerViewItem();
    }

    private void loadRecyclerViewItem() {

        list.add(new MyQuote("sample name","sample quote"));

在 MyRecyclerViewAdapter.java

public void onBindViewHolder(final MyRecycleViewAdapter.ViewHolder myholder, int position) {
        final MyQuote myQuote = myQuoteList.get(position);
        myholder.tv_author.setText(myQuote.getAuthor());
        myholder.tv_quote.setText(myQuote.getQuotedesc());
       myholder.im_favlike.setImageResource(R.drawable.fav_border);
       myholder.buttonViewOption.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

               Intent intent = new Intent (Intent.ACTION_SEND);

               intent.setType("text/plain");
               view.getContext().startActivity(Intent.createChooser(intent,"send to"));

            }
        });
    }

编辑在 MyQuote 类中实现 Parcelable 之后.. 就像这样，当我使用 intent.putParcelableArrayListExtra("mani" , MyQuote);....我得到预期的表达......在 MyRecyclerViewAdapter.java 中"

public class MyQuote  implements Parcelable{

    private String author;
    private String quotedesc;

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {

        parcel.writeString(quotedesc);
        parcel.writeString(author);
        }

    private MyQuote(Parcel parcel){

        quotedesc = parcel.readString();
        author = parcel.readString();

    }
    public static final Parcelable.Creator<MyQuote> CREATOR = new Parcelable.Creator<MyQuote>(){

        @Override
        public MyQuote createFromParcel(Parcel parcel) {
            return new MyQuote(parcel);

        }
        public MyQuote[] newArray(int size){
            return new MyQuote[size];
        }
    };

    //constructor initializing values
    public MyQuote(String author, String quotedesc) {
        this.quotedesc = quotedesc;
        this.author = author;
    }

    //getters
    public String getAuthor() {
        return author;
    }

    public String getQuotedesc() {
        return quotedesc;
    }
}

我有一个回收器卡片视图，其中包含引号和作者......作为文本视图......和一个共享按钮......在每张卡片中......当用户想要分享报价时，特定卡片的作者......他可以将引用(字符串)与作者(字符串)一起分享给消息、whatsapp 等应用程序.我该如何解决这个问题?正在实施parcelable是正确的过程..为此目的与否..如果正确，我应该在点击共享按钮时使用什么代码

 @Override
    public void onBindViewHolder(final MyRecycleViewAdapter.ViewHolder myholder, int position) {
        final MyQuote myQuote = myQuoteList.get(position);
        myholder.tv_author.setText(myQuote.getAuthor());
        myholder.tv_quote.setText(myQuote.getQuotedesc());
       myholder.im_favlike.setImageResource(R.drawable.fav_border);
       myholder.buttonViewOption.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

               Intent intent = new Intent (Intent.ACTION_SEND);

intent.putParcelableArrayListExtra("mani" , MyQuote);
               intent.setType("text/plain");
               view.getContext().startActivity(Intent.createChooser(intent,"send to"));

            }
        });
    }

推荐答案

看看这个插件 Parcelable 代码生成器.

它将帮助您为 POJO 类自动生成可打包的样板，然后您可以按照 Abhishek 的建议直接使用它intent.putParcelableArrayListExtra(key_name, list);

It will help you to auto generate parcelable boilerplate for a POJO class and then you can directly use it as suggested by Abhishek intent.putParcelableArrayListExtra(key_name, list);
