安卓網格視圖與圖像和子文本︰問題

嗨我已經開發了一個網格視圖與圖像，我已經寫了一個適配器，它工作正常，因爲網格只有一個圖像，現在我試圖把在網格只是在圖片下面的文字，從那時起，它崩潰，這裏是崩潰日誌安卓網格視圖與圖像和子文本︰問題

這裏是我的自定義適配器類

public class ImageAdapter extends BaseAdapter 
{ 
    private final String[] subText = {}; 
    Context mContext; 

    public ImageAdapter(Context _context, String[] subText) 
    { 
     super(); 
     mContext = _context; 
    } 

    public static String[] mThumbIds ={}; 
    public static String[] mVideoIds = {}; 

    public static final String[] SubText = new String[] { 
      "text1", "text2","text3", "text4","text1", "text2","text3", "text4" ,"text1", "text2","text3", "text4" ,"text1", "text2","text3", "text4" }; 

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

    @Override 
    public Object getItem(int position) { 
    return mThumbIds[position]; 
} 

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

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

     // Add The Image!!! 
     View gridView; 

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

     gridView = new View(mContext); 

     gridView = inflater.inflate(R.layout.grid_item,null); 

     //add Text 
     TextView textView = (TextView)gridView.findViewById(R.id.grid_item_text); 
     textView.setText(SubText[position]); 


     ImageView imageView = (ImageView) gridView.findViewById(R.id.grid_item_image); 
     imageView.setImageURI(Uri.parse(mThumbIds[position])); 
     imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
     imageView.setLayoutParams(new GridView.LayoutParams(150, 150)); 
     return gridView; 
    } 

}

可有人plase告訴我，正是我去錯誤。

此行

imageView.setLayoutParams(new GridView.LayoutParams(150, 150));

應改爲

gridView.setLayoutParams(new GridView.LayoutParams(150, 150));

這個錯誤是因爲您的自定義充氣視圖有LinearLayout PARAMS當GridView的期待GridView佈局PARAMS

由於一噸男人，我居然評論說，防止應用程序崩潰的行，我試過我們修復，現在工作正常。 –

問題很明顯：您正試圖將android.widget.AbsListView $ LayoutParams轉換爲android.widget.LinearLayout $ LayoutParams。

更改此：

imageView.setLayoutParams(new GridView.LayoutParams(150, 150));

有了這個：

imageView.setLayoutParams(new TheLayoutYouUseOnGrid_item.LayoutParams(150, 150));

我看到你正在爲網格的每個項目，R.layout.grid_item膨脹的自定義佈局。所以當你在你的ImageView中改變參數時，你必須將ImageView包含在其中的LayoutParams。

另外我認爲你不是很好地編寫getView方法。如果可以，發佈您的grid_item佈局。
