GridView图片溢出内存

如果GridView图片过多，连续几次打开关闭程序就会溢出内存

解决办法

@Override 
protected void onPause() { 
    GridView gridView = (GridView) findViewById(R.id.public_photos); 
    int count = gridView.getCount(); 
    for (int i = 0; i < count; i++) { 
        ImageView v = (ImageView) gridView.getChildAt(i); 
        if (v != null) {              if (v.getDrawable() != null) v.getDrawable().setCallback(null); 
        } 
    } 
    super.onPause(); 
}
