應用程序崩潰，因爲ImageAdapter /的GridView的

Question

每次測試我的應用程序，它在啓動畫面後崩潰，並讓這樣的錯誤：

02-14 13:03:29.305: A/libc(9935): Fatal signal 11 (SIGSEGV) at 0x0000015c (code=1), thread  9935 (ter.planyourday) 

和

02-14 13:03:29.260: E/dalvikvm-heap(9935): Out of memory on a 2381200-byte allocation. 

我ImageAdapter看起來是這樣的：

public class ImageAdapter extends BaseAdapter { 
private Context context; 
private final String[] buttonValues; 

public ImageAdapter(Context context, String[] buttonValues) { 
    this.context = context; 
    this.buttonValues = buttonValues; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 

    LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    View gridView; 

    if (convertView == null) { 

     gridView = new View(context); 

     // get layout from mobile.xml 
     gridView = inflater.inflate(R.layout.mobile, null); 

     // set image based on selected text 
     ImageView imageView = (ImageView) gridView 
       .findViewById(R.id.grid_item_image); 

     String button = buttonValues[position]; 

     if (button.equals("homework")) { 
      imageView.setImageResource(R.drawable.button_homework); 
     } else if (button.equals("schedule")) { 
      imageView.setImageResource(R.drawable.button_schedule); 
     } else if(button.equals("planner")) { 
      imageView.setImageResource(R.drawable.button_planner); 
     }else{ 
      imageView.setImageResource(R.drawable.button_settings); 
     } 

    } else { 
     gridView = (View) convertView; 
    } 

    return gridView; 
} 

@Override 
public int getCount() { 
    return buttonValues.length; 
} 

@Override 
public Object getItem(int position) { 
    return null; 
} 

@Override 
public long getItemId(int position) { 
    return 0; 
} 

    } 

而這裏的主要活動方法：

static final String[] MOBILE_OS = new String[] { "homework", "schedule", 
     "planner", "settings" }; 
private void setGridView() { 
    gridView = (GridView) findViewById(R.id.gridView1); 

    gridView.setAdapter(new ImageAdapter(this, MOBILE_OS)); 

    gridView.setOnItemClickListener(new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View v, 
       int position, long id) { 
      switch (position) { 
      case 0: 
       Intent startHomework = new Intent(HomeScreen.this, 
         HomeworkScreen.class); 
       HomeScreen.this.startActivity(startHomework); 
       break; 
      case 1: 
       Intent startSchedule = new Intent(HomeScreen.this, 
         ScheduleScreen.class); 
       HomeScreen.this.startActivity(startSchedule); 
       break; 

      case 2: 
       Intent startPlanner = new Intent(HomeScreen.this, 
         PlannerScreen.class); 
       HomeScreen.this.startActivity(startPlanner); 

       break; 

      case 3: 
       Intent startSettings = new Intent(HomeScreen.this, 
         SettingScreen.class); 
       HomeScreen.this.startActivity(startSettings); 
       break; 
      } 

     } 
    }); 

} 

我希望有人能幫助我！

Answer 1

這是因爲，你不使用圖像的延遲加載正確。

正確的方法是：

public View getView(int position, View convertView, ViewGroup parent) { 

    LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    View gridView; 

    ImageView imageView; 

    String button; 

    if (convertView == null) { 

      gridView = new View(context); 

      // get layout from mobile.xml 
      gridView = inflater.inflate(R.layout.mobile, null); 

      // set image based on selected text 
      imageView = (ImageView) gridView 
        .findViewById(R.id.grid_item_image);  
     } else { 
      gridView = (View) convertView; 
     } 
     button = buttonValues[position]; 

     if (button.equals("homework")) { 
       imageView.setImageResource(R.drawable.button_homework); 
      } else if (button.equals("schedule")) { 
       imageView.setImageResource(R.drawable.button_schedule); 
      } else if(button.equals("planner")) { 
       imageView.setImageResource(R.drawable.button_planner); 
      }else{ 
       imageView.setImageResource(R.drawable.button_settings); 
      } 

    return gridView; 
} 

編輯：現在有了這個getView取代你的getView（）（）。

即使這不是最好的方法。你應該創建一個持有人，以保持你的觀點正確。

如果您使用4.1.2或更高版本的ics，您的問題可能與此site的問題狀態有關。

這裏解釋說，最新版本的Android有一種不同類型的垃圾收集器，它以不同的方式處理大數據。我有同樣的問題，並通過使用較小的圖像解決。我希望這能解決你的問題。
