與spinners之間的數據傳輸

進出口試圖從多個旋轉器（搜索活性）選擇的數據傳輸到另一個活動（JSON搜索結果活性）

並在結束我有按鈕打開搜索結果

搜尋活動：我有java的微調

ArrayAdapter<CharSequence> whatlist = ArrayAdapter.createFromResource(this, 
R.array.whatlist, android.R.layout.simple_spinner_item); 
whatlist.setDropDownViewResource(R.layout.spinner_style); 
spwhat = (Spinner) findViewById(R.id.spWhat); 
spwhat.setAdapter(whatlist); 
spwhat.setOnItemSelectedListener(new MyOnItemSelectedListener());

和MyOnItemSelectedListener

public class MyOnItemSelectedListener implements OnItemSelectedListener { 
     public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) { 

      strs = new Bundle(); 
      Intent i = new Intent(SearchActivity.this, SearchResult.class); 
      strs.putString("setwhat", parent.getItemAtPosition(pos).toString()); 
      i.putExtras(strs); 

     } 
     public void onNothingSelected(AdapterView<?> arg0) {} 
    }

這是按鈕

btnsearch = (Button)findViewById(R.id.btnSearch); 
btnsearch.setOnClickListener(new View.OnClickListener() { 

     public void onClick(View v) { 

      Intent ia = new Intent(SearchActivity.this, SearchResult.class); 
      SearchActivity.this.startActivity(ia); 
     } 
    });

這是在搜索結果

Bundle extras = getIntent().getExtras(); 
    if(extras!=null){ 


      Integer item = extras.getInt("setwhat"); 
      //Use a switch(item) here to switch to different links based on selection 
      TextView tv = (TextView) findViewById(R.id.tvtv); 
      tv.setText("Another Activity, Item is :" + item.toString());

文本不會改變。我已經嘗試了網絡上的任何教程，並在這裏尋找一個解決方案的小時.. 任何人都可以幫忙嗎？

你甚至不需要你的微調監聽器。只需將您的按鈕的onclick更改爲：

btnsearch = (Button)findViewById(R.id.btnSearch); 
btnsearch.setOnClickListener(new View.OnClickListener() { 

    public void onClick(View v) { 

     Spinner spwhat = (Spinner) findViewById(R.id.spWhat); 

     Intent ia = new Intent(SearchActivity.this, SearchResult.class); 
     ia.putExtra("setwhat", spwhat.getSelectedItem().toString()); 
     startActivity(ia); 
    } 
});
