窗口已滿應用程序啓動時使用GridView

以下是我的gridbuilder類正在啓動應用程序的mainactivity中使用。窗口已滿應用程序啓動時使用GridView

public class GridBuilderActivity extends BaseAdapter { 

    private Context mcontext; 
    private final String[] featurename; 
    private final int[] Imageid; 

    public GridBuilderActivity(Context context, String[] featurename, int[] Imageid) { 

     mcontext = context; 
     this.featurename = featurename; 
     this.Imageid = Imageid; 
    } 

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

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

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

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View grid; 
     LayoutInflater inflater = (LayoutInflater) mcontext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     if (convertView == null) { 
      grid = new View(mcontext); 
      grid = inflater.inflate(R.layout.grid_layout, null); 
      TextView textView = (TextView) grid.findViewById(R.id.gridtextview); 
      ImageView imageView = (ImageView) grid.findViewById(R.id.gridimage); 
      textView.setText(featurename[position]); 
      imageView.setImageResource(Imageid[position]); 


      //Density wise text size fixing 
      float density = mcontext.getResources().getDisplayMetrics().density; 
      if (density >= 4.0) { 
       //System.out.println("Ex"); 
       textView.setTextSize(15); 
      } 
      if (density >= 3.0) { 
       //System.out.println("hp"); 
       textView.setTextSize(14); 
      } 
      if (density >= 2.0) { 
       //System.out.println("xhp"); 
       textView.setTextSize(13); 

      } 
      if (density >= 1.5) { 
       //System.out.println("hpin"); 
       textView.setTextSize(12); 

      } 
      if (density >= 1.0) { 
       // System.out.println("mp"); 
       textView.setTextSize(11); 

      } 
//Fixing finished here 

     } else { 
      grid = (View) convertView; 
     } 
     return grid; 
    } 
}

在對應用程序啓動許多手機我m如果低於警告和電話保持後應用程序啓動幾秒鐘掛。

請幫助如何解決這個問題。這嚴重影響了應用程序的性能。我通過傳遞必要的參數來調用mainactivity。如下佈局

嘗試在清單文件中添加此在標記中的android：largeHeap =「true」。 –

這已經添加 – Panache

圖片你正在加載的是創建加載的問題 –

你可以試試這個它是我用過GridLayoutManager在RecyclerView更換的GridView

<android.support.v7.widget.RecyclerView 
    android:id="@+id/recycler_view_single_item" 
    android:layout_width="match_parent" 
    android:layout_height="400dp" 
    android:scrollbars="vertical" />

recycler_view_single_item.xml
