Java多维数组-如何从微调器读取值

Question

Hello i have 2 drop downs .First drop down[Spinner1] has 4 values , second[Spinner2]has 5 values. 您好，我有2个下拉菜单。第一个下拉[Spinner1]有4个值，第二个[Spinner2]有5个值。

Now when user selects values from first drop down and another value from second drop down , a fragment shows up in a part of screen with a webview text. 现在，当用户从第一个下拉菜单中选择值，然后从第二个下拉菜单中选择另一个值时，屏幕上将显示一个带有Webview文本的片段。

This is my code 这是我的代码

import android.R.string;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.widget.AdapterView;

public class WebViewerFragment extends Fragment {

    private WebView mWebView;
    // a two dimensional array representing the data to put in the WebView

String SurgEqui="<html><body><h2>Equipment</h2><ul><li><p>IV catheter :Be certain that IV is in place and flushing easily</p></li></body><html>";

     String[][] mData      = new String[4][5]; 




    /*   String [][]mData={{Surg,Surg,Surg,Surg,Surg},{Surg,Surg,Surg,Surg,Surg}
{Surg,Surg,Surg,Surg,Surg}{Surg,Surg,Surg,Surg,Surg}{Surg,Surg,Surg,Surg,Surg}}

  */


    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View mainView = (View) inflater.inflate(R.layout.frag_layout, container, false);
        mWebView = (WebView) mainView.findViewById(R.id.webView1); 
        return mainView;
    }

    public void updateWebView(int firstSelection, int secondSelection) {
         if (firstSelection == AdapterView.INVALID_POSITION || secondSelection == AdapterView.INVALID_POSITION) {
              return;  
         } else {
              if (mWebView != null) {
                   mWebView.loadData(mData[firstSelection][secondSelection], "text/html", null);
              }
         }

    }


}

Now there are 20 html string combinations for these 2 drop downs.How can i use this array for storing and retrieving values.How can i insert 20 HTML strings into array so that i can use mWebView.loadData(mData[firstSelection][secondSelection], "text/html", null); 现在这20个下拉列表有20个html字符串组合。如何使用此数组存储和检索值。如何将20个HTML字符串插入数组，以便可以使用mWebView.loadData（mData [firstSelection] [secondSelection] ，“ text / html”，null）； method to read values to display in webview. 读取要在webview中显示的值的方法。

wouldn't it be best to just use 2 arrays? 最好只使用2个数组？ or even just 1 array with 20 entries? 甚至只有1个数组和20个条目？ If you must use your method, what issues are you running into exactly? 如果必须使用您的方法，那么您到底遇到了什么问题？ what you commented out is almost correct: 您评论的内容几乎是正确的：

String [][] mData= {
        {Surg,
            Surg,
            Surg,
            Surg,
            Surg},
        {Surg,
            Surg,
            Surg,
            Surg,
            Surg}, //<-- need comma between brackets
        {Surg,
            Surg,
            Surg,
            Surg,
            Surg}, 
        {Surg,
            Surg,
            Surg,
            Surg,
            Surg},
        {Surg,
            Surg,
            Surg,
            Surg,
            Surg}
        }; // <-- don't forget the semicolon
