这个问题最初是针对Android 1.6提出的.

我在我的应用程序中处理照片选项.

我的Activity中有一个按钮和一个ImageView.当我点击按钮时,它会重定向到图库,我可以选择一个图像.所选图像将出现在我的ImageView中.

我正在尝试将galery中的照片添加到a ImageView但是我收到此错误:

java.lang.RuntimeException:将结果ResultInfo {who = null,request = 1,result = -1,data = Intent {dat = content:// media/external/images/media/1}}传递给activity {hotMetter. pack/hotMetter.pack.GetPhoto}:java.lang.NullPointerException

这是我的代码:

      Intent intent = new Intent();
      intent.setType("image/*");
      intent.setAction(Intent.ACTION_GET_CONTENT);

      startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
Bitmap bitmap=null;
public void onActivityResult(int requestCode, int resultCode, Intent data)
{

    if (resultCode == Activity.RESULT_OK)
    {
        if (requestCode == SELECT_PICTURE) 
        {
             Uri selectedImageUri = data.getData();           
             selectedImagePath = getPath(selectedImageUri);             
             tv.setText(selectedImagePath);
             img.setImageURI(selectedImageUri); 
         }
    }


 public String getPath(Uri uri) 
    {
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(uri, projection, null, …
