昨晚我发布了一个有关这个问题的问题，但我认为我没有解释好，无法得到适当的帮助。所以基本上，我有一个应用程序，您可以按下按钮，选择来自您的图库的图像，并在应用程序中显示我显示的ImageView中显示它。这一切都很好。但是，当我再次按下按钮并选择不同的图片时，应用程序会强制关闭。
更新 现在，如果我从图库中下载照片文件夹中拍照，就可以正常工作，可以随意更换照片。但是当我回到我的相机相册中更改图片时，它会强制关闭。
更新2 它也可以在我在Gallery应用中拥有的任何其他文件夹中正常工作。唯一存在此问题（强制关闭）的是“相机”文件夹。
更新3 19660800字节的外部分配对于此进程过大，导致了此问题。有什么方法可以减小所选照片的大小吗？
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
private ImageView img;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img = (ImageView)findViewById(R.id.myimageview);
((Button) findViewById(R.id.taptoadd))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
