我不知道我的代碼中存在什麼問題。我想在GridView中顯示一些圖像,但顯示的圖像非常小,高分辨率圖像也一樣。請幫忙。提前致謝。GridView單元格的尺寸不變

我不知道該怎麼做。我也張貼我的代碼。

activity_main.xml中文件

<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_height="match_parent" 
android:layout_width="match_parent"> 

<GridView 
    android:id="@+id/gridview_stickers" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:columnWidth="90dp" 
    android:numColumns="auto_fit" 
    android:horizontalSpacing="10dp" 
    android:verticalSpacing="10dp" 
    android:stretchMode="columnWidth" 
    android:gravity="center"> 

</GridView> 

gridview_items.xml文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:layout_gravity="center_horizontal" 
android:orientation="vertical" 
android:background="#000000"> 

<ImageView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/sticker" 
    android:scaleType="centerCrop" 
/> 

getView的AdapterClass

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

    View imageView = convertView; 
    ImageView picture; 


    if(imageView == null) { 
     imageView = inflater.inflate(R.layout.gridview_items, parent, false); 
     imageView.setTag(R.id.sticker, imageView.findViewById(R.id.sticker)); 
     imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); 
     imageView.setPadding(8, 8, 8, 8); 

    } 
     picture = (ImageView)imageView.getTag(R.id.sticker); 
     picture.setImageBitmap(img.get(position).imageBitmap); 

    return imageView; 
}

最後我想出了自己。我改變了

imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); 

imageView.setLayoutParams(new GridView.LayoutParams(300, 300)); 

,我得到了想要的結果。
