GridView can not display images, an error: outofMemory

This error always ran to:



This is my xml code

 xmlns: tools = "http://schemas.android.com/tools" 
android: layout_width = "match_parent" 
android: layout_height = "match_parent" 
android: paddingBottom = "@ dimen / activity_vertical_margin" 
android: paddingLeft = "@ dimen / activity_horizontal_margin" 
android: paddingRight = "@ dimen / activity_horizontal_margin" 
android: paddingTop = "@ dimen / activity_vertical_margin" 
tools: context = ". MainActivity"> 

android: id = "@ + id / gridview" 
android: layout_width = "fill_parent" 
android: layout_height = "fill_parent" 
android: numColumns = "3"> 
 

 

This is the code
my java source files

 package com.siyehuazhilian.gridviewdemo; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemClickListener; 
import android.widget.GridView; 

public class MainActivity extends Activity {
/ / Declare a control object 
private GridView gridView = null; 

@ Override 
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState); 
setContentView (R.layout.activity_main); 
/ / To get the corresponding controls 
 by idgridView = (GridView) findViewById (R.id.gridview); 

/ / Set the adapter for the control 
gridView.setAdapter (new ImageAdapter (this)); 

/ / Bind the GridView listener 
gridView.setOnItemClickListener (new OnItemClickListener () {

@ Override 
public void onItemClick (AdapterView  arg0, View arg1, int arg2, 
long arg3) {
System.out.println ("sub-element was clicked"); 
} 
}); 

} 

@ Override 
public boolean onCreateOptionsMenu (Menu menu) {
getMenuInflater () inflate (R.menu.main, menu);. 
return true; 
} 

} 

Which custom adapter code below:

 package com.siyehuazhilian.gridviewdemo; 

import java.lang.reflect.Field; 
import java.util.ArrayList; 

import android.content.Context; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.GridView; 
import android.widget.ImageView; 

public class ImageAdapter extends BaseAdapter {
/ / Resource id array 
private ArrayList  imgIds = new ArrayList  (); 
/ / Context object 
private Context context; 

public ImageAdapter (Context context) {
this.context = context; 
/ / Get resources through reflection and the id is stored in the id array 
Field [] fields = R.drawable.class.getDeclaredFields (); 
for (int i = 0; i / / Only the file name contains the img will be read 
if (fields [i]. getName (). contains ("img")) {
try {
imgIds.add (fields [i] getInt (R.drawable.class).); 
} Catch (IllegalArgumentException e) {
e.printStackTrace (); 
} Catch (IllegalAccessException e) {
e.printStackTrace (); 
} 
} 
} 
} 

@ Override 
public int getCount () {
return imgIds.size (); 
} 

@ Override 
public Object getItem (int position) {
return imgIds.get (position); 
} 

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

@ Override 
public View getView (int position, View convertView, ViewGroup parent) {
ImageView imageView; 
if (convertView == null) {
imageView = new ImageView (context); 
imageView.setLayoutParams (new GridView.LayoutParams (85, 85)); 
imageView.setScaleType (ImageView.ScaleType.FIT_CENTER); 
} Else {
imageView = (ImageView) convertView; 
} 

imageView.setImageResource (imgIds.get (position)); 
return imageView; 
} 

}
