解决方案   

我想从图库中选择图片，并试图在显示它   gridview的，但它未在gridview的设定

执行以下变化ImageAdapter类：

1 返回 ArrayList的大小从 getCount将方法：

 公众诠释getCount将（）{
    返回arrayList.size（）;
}
 

2 创建于当前适配器的数据源增加新的选择图像的方法：

 无效addToList（字符串strPath中）
{
    this.arrayList.add（strPath的）;
    this.notifyDataSetChanged（）;
}
 

现在在 onActivityResult 呼叫 addToList 方法来显示在GridView中所选图像：

 参数：columnIndex = cursor.getColumnIndex（filePathColumn [0]）;
字符串picturePath = cursor.getString（参数：columnIndex）;
objImageAdapter.addToList（picturePath）;
cursor.close（）;
 

I am trying to select image from gallery and trying to display it in gridview but it is not setting in gridview,following is my snippet code,can anyone tell me what is the issue with my code? Thanks in advance

public class MainActivity extends Activity {

private static int RESULT_LOAD_IMAGE = 1;
private ImageView imageView;
private Uri selectedImage;
private int columnIndex;
private GridView gridView;
private String picturePath;
private ImageView imageView11;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
    gridView = (GridView) findViewById(R.id.gridview);
    gridView.setAdapter(new ImageAdapter(this));

    gridView.setOnItemClickListener(new OnItemClickListener() 
    {
        public void onItemClick(AdapterView<?> parent, 
        View v, int position, long id) 
        {                
            Toast.makeText(getBaseContext(), 
                    "pic" + (position + 1) + " selected", 
                    Toast.LENGTH_SHORT).show();
        }
    });        
    buttonLoadImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setType("image/*");
            startActivityForResult(intent, 1);
        }

        Cursor cursor = getContentResolver().query(selectedImage,

        cursor.moveToFirst();



        imageView = (ImageView) findViewById(R.id.imgView);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

        columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        objImageAdapter.addToList(picturePath);
        cursor.close();


    }

I am trying to select image from gallery and trying to display it in gridview but it is not setting in gridview

Do following Changes in ImageAdapter class :

1. Return size of arrayList from getCount method:

public int getCount() {
    return arrayList.size();
}

2. Create a method for adding new selected image in current adapter data-source :

void addToList(String strPath)
{
    this.arrayList.add(strPath);
    this.notifyDataSetChanged();
}

Now in onActivityResult call addToList method to show selected image in GridView:

columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
objImageAdapter.addToList(picturePath);
cursor.close();
