我怎样才能把可绘制的大图像到android的gridview？

-1

我想从可绘制到gridview设置大图像。我已经完成了这个代码，但我得到了错误。我怎样才能把可绘制的大图像到android的gridview？

这是我的片段布局名称color_fragment.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="@color/black_overlay"> 
    <GridView 
     android:id="@+id/gridview" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:numColumns="3" 
     android:columnWidth="90dp" 
     android:horizontalSpacing="10dp" 
     android:verticalSpacing="10dp" 
     android:gravity="center" 
     android:stretchMode="columnWidth" > 
    </GridView> 
</LinearLayout>

这里，是我的ColorFragment.java其中充气上述布局

public class ColorFragment extends Fragment { 
    View view; 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     view=inflater.inflate(R.layout.watercolor_fragment, container, false); 
     GridView gridView=(GridView)view.findViewById(R.id.gridview); 
     gridView.setAdapter(new ImageAdapter(view.getContext())); 
     return view; 
    } 
}

这里，是我的ImageAdapter

public class ImageAdapter extends BaseAdapter { 

    private Context context; 

    private Integer[] mThumbIds={R.drawable.natureone,R.drawable.naturetwo, 
           R.drawable.naturethree,R.drawable.naturefour, 
           R.drawable.naturefive,R.drawable.naturesix, 
           R.drawable.natureseven,R.drawable.natureight, 
      R.drawable.naturenine,R.drawable.natureten,R.drawable.natureleven,R.drawable.naturetwelve, 
      R.drawable.naturethrtineen,R.drawable.naturefourthyeen,R.drawable.naturefifteen,R.drawable.naturesixteen, 
      R.drawable.natureseventeen,R.drawable.natureone}; 
    public ImageAdapter(Context context){ 
     this.context=context; 
    } 
    @Override 
    public int getCount() { 
     return mThumbIds.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) { 
     ImageView imageView; 
     if(convertView==null){ 
      imageView=new ImageView(this.context); 
      imageView.setLayoutParams(new GridView.LayoutParams(85,85)); 
      imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
      imageView.setPadding(8,8,8,8); 
     } 
     else{ 
      imageView=(ImageView)convertView; 
     } 
     imageView.setImageResource(mThumbIds[position]);//Got Error here 
     return imageView; 
    } 
}

在上面的代码中，所有的图像都是高清的，它已经存在于xhdpi文件夹中。

我得到了错误

如何解决这个问题？我的问题是为什么我得到OOM错误？请帮助我解决这个错误。

您的图片可能是高分辨率图片。 – Piyush

你想调整图像位图吗？ –

如何使用位图调整图像大小以及如何放入imageView？ –

这将调整图像Bitmap。用于从drawable获取图像位图。

Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.yourImageName);

之后，重新大小，该图像位图使用下面的代码。

int height = (bitmap.getHeight() * 512/bitmap.getWidth()); 
Bitmap scale = Bitmap.createScaledBitmap(bitmap, 512,height, true);

创建图像位图后，使用下面的代码设置该位图。

imageview.setImageBitmap(scale);

但我有一个图像阵列。我不是在谈论单个图像。 –

如何在片段中调用 –

什么是getResources（）？ –

四件事情，我需要在ImageAdpter.java

添加

Bitmap bitmap=BitmapFactory.decodeResource(context.getResources(),mThumbIds[position]); 
     int height = (bitmap.getHeight() * 512/bitmap.getWidth()); 
     Bitmap scale = Bitmap.createScaledBitmap(bitmap, 512,height, true); 
     imageView.setImageBitmap(scale);

这条线之下，从我的岗位在ImageAdapter.java

imageview.setImageResources(mThumbIds[position]);//Remove this line

因为，我需要调整//删除所有的图像。位图提供了一种调整图像大小和存储到imageview的方法。
