安卓聽衆內部的監聽器按鈕

我有以下代碼...此列表基本上是「監聽」要點擊的項目，並且一旦單擊，它就會打開一個帶有按鈕的對話框。我無法使按鈕聽...即使我這樣做...應用程序將崩潰。和Eclipse不會自動讓我「超馳」的的onClick（）安卓聽衆內部的監聽器按鈕

WeatherAdapter adapter = new WeatherAdapter(this,R.layout.listview_header_row, weather_data); 
      listView1 = (ListView)findViewById(R.id.listView1);

      //listView1.addHeaderView(header); 
      listView1.setAdapter(adapter);

替換此代碼..

因爲您的按鈕位於對話框內，因此您需要使用對話框視圖。

WeatherAdapter adapter = new WeatherAdapter(this,R.layout.listview_header_row, weather_data); 
     listView1 = (ListView)findViewById(R.id.listView1); 
     View header = (View)getLayoutInflater().inflate(R.layout.listview_header_row, null); 
     //listView1.addHeaderView(header); 
     listView1.setAdapter(adapter); 
     listView1.setClickable(true); 
     listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) { 

       Dialog dialog = new Dialog (Activity2.this); 
       dialog.setContentView(R.layout.dialogxml); 
       dialog.setCancelable(true); 
       ImageView dcover=(ImageView) dialog.findViewById(R.id.dimageView1); 
       TextView dtitle = (TextView) dialog.findViewById(R.id.dtextView1); 
       TextView dyear = (TextView) dialog.findViewById(R.id.dtextView2); 
       TextView ddirector = (TextView) dialog.findViewById(R.id.dtextView3); 
       TextView drating = (TextView) dialog.findViewById(R.id.dtextView4); 
       TextView len1 = (TextView) dialog.findViewById(R.id.textView77); 
       Button postbutton=(Button) dialog.findViewById(R.id.buttonfb); 

       InputStream is; 
       try { 
        is = (InputStream) new URL(full_data[position][0]).getContent(); 
        Drawable dd = Drawable.createFromStream(is, "src name"); 
        dcover.setImageDrawable(dd); 
       } catch (MalformedURLException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 


       dtitle.setText("Name: "+full_data[position][1]); 
       dyear.setText("Year: "+full_data[position][2]); 
       ddirector.setText("Director: "+full_data[position][4]); 
       drating.setText("Rating: "+full_data[position][3]+"/10"); 
       dialog.show(); 
      postbutton.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View v) { 

        } 
        }); 


      }

陷入錯誤

按鈕postbutton =（按鈕）findViewById（R.id.buttonfb）;應該是

Button postbutton =（Button）dialog.findViewById（R.id.buttonfb）;如果按鈕在對話框內。

非常感謝...工作！ –

-我覺得postbutton是dialog裏面，如果它的，所以你需要找到它id下列方式......

Button postbutton=(Button)dialog.findViewById(R.id.buttonfb);
