我想从MainActivity转到大学活动，但它总是给我这个错误。
我意识到错误的原因是GridView，但如果你能弄明白的话，我将不胜感激。
public class MainActivity extends AppCompatActivity {
ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.anasayfa);
imageView = (ImageView)findViewById(R.id.imageView);
View.OnClickListener clickListener = new View.OnClickListener() {
public void onClick(View v) {
if (v.equals(imageView)) {
Intent nextScreen = new Intent(getApplicationContext(), Universiteler.class);
startActivity(nextScreen);
}
}
};
imageView.setOnClickListener(clickListener);
}
}
Universiteler code:
public class Universiteler extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_universiteler);
GridView gridView = (GridView)findViewById(R.id.gridView);
gridView.setAdapter((BaseAdapter) new ImageAdapter(this));
}
public class ImageAdapter extends BaseAdapter {
Context mcontext;
public ImageAdapter(Context c)
{
mcontext=c;
}
public int getCount() { //eleman sayısını tutuyo
// TODO Auto-generated method stub
return dizi.length;
}
//secilen elemanın konumunu tutuyo
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ImageView imageview;
if(convertView==null){
imageview=new ImageView(mcontext);
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(dizi[position]);
return imageview;
}
private Integer[] dizi={
R.drawable.abantizzetuni,R.drawable.abdullahguluni,R.drawable.adanabilimuni,R.drawable.adnanmenderesuni,
R.drawable.afyonuni,R.drawable.agriibrahimuni,R.drawable.ahievranuni,R.drawable.aidyamanuni,R.drawable.akdenizuni,
R.drawable.aksarayuni
};
/*Burada ekranda gözükmesini istediğimiz resimleri bir diziye atıyoruz.Bu resimleri de drawable klasöründen çekiyoruz*/
}
}
这是我的LOGCAT：

答案 0 :(得分：2)
解决方案1：您可以在activity的清单中使用android：largeHeap =“true”来请求更大的堆大小，但这不适用于任何预装的Honeycomb设备。
解决方案2：使用像Universal Image Loader
这样的Image Loader库这使得加载大型图像文件时头痛不已，还支持一些额外的功能，如缓存和转换。
here是示例用法。
