通过Intent从一个类传递数据到另一个类并且无法捕获它？

Question

我有两个这样的String Arrays,

String[] htmlArray = {
      "file:///android_asset/Pinocchio/OPS/chapter-001.xml",
      "file:///android_asset/Pinocchio/OPS/chapter-002.xml",

      "file:///android_asset/Pinocchio/OPS/chapter-035.xml",
      "file:///android_asset/Pinocchio/OPS/chapter-035.xml" 
};

String[] htmlArray1 = {
      "file:///android_asset/Harry_Potter/OEBPS/part1.xhtml",
      "file:///android_asset/Harry_Potter/OEBPS/part2_split_000.xhtml",

      "file:///android_asset/Harry_Potter/OEBPS/part18_split_000.xhtml",
      "file:///android_asset/Harry_Potter/OEBPS/part18_split_001.xhtml", 
};

然后,我把两个ImageView放在另一个类中,

private void init() {
    pino_cover = (ImageView) findViewById(R.id.pino_cover);
    pino_cover.setOnClickListener(new View.OnClickListener() {

      @Override
      public void onClick(View v) {
        Intent reader=new Intent(instance,ReaderScreen.class);
        reader.putExtra("pino",true);
        startActivity(reader);
      }
    });

    harry_cover=(ImageView) findViewById(R.id.harry_cover);
    harry_cover.setOnClickListener(new View.OnClickListener() {

      @Override
      public void onClick(View v) {
        Intent reader=new Intent(instance,ReaderScreen.class);
        reader.putExtra("harry",true);
        startActivity(reader);
      }
    });
  }

然后,如果我点击Pino图像,我可以通过htmlArray获取数据.

Intent i=getIntent();
      Bundle b = i.getExtras();
       String newText = b.
       String setext=b.getString("harry");
      if (newText=="pino")    
        pages = htmlArray;    
      else
        pages = htmlArray1;

但是,如果我点击Harry图像,那么它也会被用来获取数据htmlArray.我想得到htmlArray1.我怎么能得到？

你只是为你的意图添加一个布尔值,但是你可以使用.putExtra(mStringArray, htmlArray1);这个方法存在来通过意图传递数组......？另外,比较在Java中的两个字符串,你不能这样做==,但.equals("").在你的情况下if(newText.equals("harry))......

编辑 好了,在一个更简单的版本中,你有:

Intent i=getIntent();
  Bundle b = i.getExtras();
   String newText = b.
   String setext=b.getString("harry");
  if (newText=="pino")    
    pages = htmlArray;    
  else
    pages = htmlArray1;

替换它:

Intent i=getIntent();
  Bundle b = i.getExtras();
   String newText = b.
   String setext=b.getString("harry");
  if (newText.equals("pino"))    
    pages = htmlArray;    
  else
    pages = htmlArray1;

这应该在逻辑上有效.
